The posterior palatal seal: Its rationale and importance: An overview
Shelly Goyal, Mukesh K Goyal, Dhanasekar Balkrishanan, Veena Hegde, Aparna I Narayana
May-August 2014, 2(2):41-47
The location and preparation of the posterior palatal seal is frequently neglected procedure. This seal contributes significantly to the retention of a maxillary complete denture. Hundreds of dentures have failed due to the improper establishment of the distal limit and to an improper posterior palatal seal. Its location and preparation on the master cast are often done by the dentist or dental technician without reference to anatomical landmarks of the mouth. Various methods of achieving posterior palatal seal and reproducing it in the maxillary denture have been described in the literature. This article aims toward rationale and importance of posterior palatal seal, anatomical reference landmarks, functions, methods to record, and discusses various problems associated with recording posterior palatal seal.

Implant protected occlusion: A comprehensive review
Sagar J Abichandani, Nandakishore Bhojaraju, Satyabodh Guttal, J Srilakshmi
May-August 2013, 1(2):29-36
Complexities in the study of occlusion have set tough challenges for both under graduate and post-graduate students and the introduction of osseointegrated implants has further complicated these challenges. The principles of occlusion are applied by dentists for the natural dentition directly to implant-supported and retained restorations. Although successful, this rationale at times may result in overly complex or simplified treatment protocols and outcomes. The focus of this review is mainly on currently available scientific literature involving dental implant occlusion. The authors reviewed the English peer-reviewed literature prior to 1996 in a comprehensive manner, and the material post 1996 was reviewed electronically using MEDLINE. Electronic searches of the literature were performed in MEDLINE using key words - cohort studies, complete denture occlusion, clinical trial, case studies, dental implant function, dental implant occlusion, dental implant occlusion research, dental implant functional loading, dental implants, dental occlusion, dental occlusion research, denture function, denture occlusion, dentures, implant function, implant functional loading, implant occlusion, occlusion, and removable partial denture occlusion - in various combinations to obtain potential references for review. A total of 4445 English language titles were obtained, many of which were duplicates due to multiple searches. Manual hand searching of the MEDLINE reference list was performed to identify any articles missed in the original search.

Sagar J Abichandani, Ramesh Nadiger, Abhishek S Kavlekar
January-April 2013, 1(1):1-10
The implant evolution has become a "restorative driven" field, and it is therefore important to know the designing principles of abutments and its connection to the implants and its rationale for use in clinical practice. The key is to have an optimum selection and designing of the implant to meet the implant position and angulation in the clinical scenario. A search was conducted both manually and electronically to find terms that included dental implants, dental abutments, custom abutments, cast abutments, abutment-implant interface, emergence profile, soft tissue profile, provisional restoration, CAD/CAM abutments, abutment innovations, abutment designing, abutment selection, and abutment materials. A total of 4332 English titles were obtained in various combinations and were repeated and duplicated due to multiple searching. Proper short-listing of the articles was done and a comprehensive review was formulated. This review article highlights various methods and rationale behind selection, designing of various abutments, its influence on emergence profile, and the newer advances and trends that have emerged in the field of implant dentistry.

Intricate relations and concepts of reference points in prosthodontics: A literature review
Deepti Raghav, Karan Kapoor, Abdullah Ali Alqahtani, Mohammed Zaheer Kola, Fawaz Alqahtani
January-April 2016, 4(1):1-6
Oral rehabilitation presents a variety of clinical situations needing fabrication of prostheses that could satisfy the overall requirement of the patients. In various prosthodontic procedures, exact articulation of the maxillary cast to the articulator necessitates minimum three reference points that could decide the plane to which maxillary cast is mounted. Therefore, the correct choice of reference points in anterior and posterior areas is very crucial failing which one can end up with fabricating intolerable prosthesis. This reference plane is usually created by two points located posterior to the maxillae and one point located anterior to them. In general, the two posterior points are located by measuring prescribed distances from the skin surface landmarks. Literature has well evidenced various anterior and posterior points of reference used for mounting the maxillary cast on the different type of articulator systems. The most common reference plane is the Frankfort plane, which has been assumed to be horizontal when the patient is in the natural head position. However, this relationship is not simply opening or closing, but a complex relationship which exists in three dimensions. Variations may occur in any direction – superoinferior, anteroposterior, or mediolateral. Thus, it is essential to record this relationship with the least possible error to obtain a successful prosthesis.

Preventive aspect of prosthodontics: An overview
Rina Singh, Jagjit Singh, Ramandeep Singh Gambhir, Kavalbir Singh Bhinder
January-April 2015, 3(1):10-15
Prosthetic dentistry is one of the fundamental pillars of dentistry. The most effective prosthetic prophylaxis could be the prevention of causes leading to tooth extractions. As a dentist our main aim should be prevention, which not only includes prevention of caries and or periodontal disease but also prevention of residual alveolar bone loss after teeth are extracted Modern treatment options improve the overall prognosis of the stomatognathic system and the quality of life of the affected patients significantly. Preventive prosthodontics highlights the importance of any procedure that can delay or eliminate future prosthodontic problems. The present review was conducted after doing extensive literature search of peer-reviewed journals and extracting information on the concept of preventive prosthodontics. The present paper discusses the concept of preventive prosthodontics engaging all the three levels of prevention-primary, secondary and tertiary. Procedures and prosthetic interventions that can be undertaken in each level are discussed.

Conventional methods for selecting form, size, and color of maxillary anterior teeth: Review of the literature
Aysegul Kurt, Gulbahar Isik-Ozkol
September-December 2015, 3(3):57-63
One of the most confusing and difficult aspects of complete denture prosthodontics is the selection of appropriately maxillary anterior denture teeth when no preextraction records are available. Dental literature indicates that varied methods have been proposed for artificial tooth selection. The aim of this article is to review the conventional methods for maxillary anterior tooth selection and their reliabilities. A search of the dental literature in PubMed was completed for the years 1955–2015 with an emphasize on peer-reviewed dental journals limited to studies in the English language and using tooth selection and complete denture as keywords. The study works on three aspects of tooth selection: (1) Form, (2) size, and (3) color. This review of the literature demonstrates no universally reliable method of determining form and color for maxillary anterior denture teeth. But, interalar distance, interpupillary distance, and distance between the medialis angles of the eyes appear to be a reliable guide for selecting the size of maxillary anterior teeth. Information of racial differences may help identify esthetic modifications to treatment plans to include the multiple racial groups within modern societies.

Hasan Onder Gumus, Hasan Huseyin Kocaagaoglu, Tugrul Aslan, Haydar Albayrak, Burak Sagsen
May-August 2014, 2(2):48-52
Purpose: The purpose of this study was to record the prevalence of pulp exposures occurring during preparation of vital abutment teeth. Materials and Methods: 2527 patients (1495 female, 1032 male) who received metal-ceramic fixed partial dentures or single crowns were included in the study. Teeth were prepared using diamond burs in a high speed hand piece under air and water coolant. If pulpal exposure occurred, data of the patient's gender and age, tooth number, tooth position (normal vs malpositioned) and exposure time were recorded, and the patients were referred for immediate endodontic treatment. Data were analyzed using Chi-square test, with a confidence level set at 95% (P < 0.05). Results: Pulpal exposure occurred in 80 teeth (0.66%), Chi-square demonstrated no difference (P > 0.05) male-female exposure ratio (1:1.5). The difference in exposure between maxillary and mandibular teeth was statistically significant (P < 0.05). Only 28.75% of exposed tooth was malposed. The majority (n = 49, 61.25%) of exposures occurred in mandibular teeth and this was statistically significant (P < 0.05). Overall the most frequently exposed tooth was mandibular canine (20%), followed by the maxillary central incisor (13.75%) and mandibular lateral incisor (10%). Conclusions: Clinicians should undertake greater care in preparing teeth, especially mandibular canines, for fixed prosthetics. The majority (62.5%) of patients in which pulpal exposure occurred during tooth preparation were between 30-50 years old.

Kishan Singh, Suraj Suvarna, Yoshaskam Agnihotri, Sukant Sahoo, Prince Kumar
January-April 2014, 2(1):15-22
Accurate shade matching of tooth colored restoration with the adjacent dentition is essential not only at the time of fabrication but also for the life time durability. This is a factual truth for dental porcelain but in contradiction, color instability in porcelain restoration is a common dilemma nowadays, especially when they are exposed to routinely consumable beverages, which sever its nature of being tooth colored. Here the authors have attempted to highlight the historical outlooks, researches on color stability and difficulties, and current trends for color stability in tooth colored restorative materials, predominantly dental ceramics. A methodical literature search was performed using MEDLINE/PubMed and other scholarly research bibliographic databases using Medical Subject Headings (MeSH) from 1953 to 2013. Most of the studies suggest and evidence that there is no ceramic available, which could be classified as total stain free; however, there is wide diversity in their color stability and surface characteristics seen with different oral conditions both qualitatively and quantitatively.

Applications of silver nanoparticles in prosthodontics: An overview
Rajashree Dhananjay Jadhav, Shreenivas V Bhide, B. L. V. Prasad, Jayesh Shimpi
September-December 2016, 4(3):45-50
Silver (Ag) has been in use in medicine since time immemorial because of its antimicrobial properties. However, due to the emergence of antibiotics, the use of Ag has been declined. Several pathogenic bacteria have developed resistance against various antibiotics. This has led to the reemergence of Ag. Recently, nanoscience and nanotechnology are gaining tremendous popularity. The small size of nanoparticles provides larger surface area and hence increases the effectiveness of nanoparticles. Ag nanoparticles (AgNPs) are used in medical and dental applications ranging from Ag-based wound dressings, Ag-coated medical devices such as catheters, bone cements, in gels, lotions, cosmetics, in dental restorative materials, endodontic cements, dental implants' caries inhibitory agents, and in prosthesis. This paper reviews the use of AgNPs as an antimicrobial in oral prosthesis.

Deepti Raghav, Satyavir Singh, Mohammed Zaheer Kola, Altaf Hussain Shah, Hesham Saleh Khalil, Prince Kumar
September-December 2014, 2(3):76-81
Aim: Gingival deflection techniques can be classified as mechanical, mechanochemical, surgical, or any combination. Comparative evaluations of gingival retraction systems are done rarely mainly because there is no consensus on the evaluation criteria. Therefore, this study aimed to evaluate the efficacy of three different gingival retraction systems, i.e., Magic Foam Cord, expasyl paste, and aluminium chloride-impregnated retraction cord. Materials and Methods: Following impressions, obtained casts were measured for gingival sulcus opening width under optical microscope (with imaging system software). The presence of bleeding after removal of material, ease of procedure, and patient's comfort were also evaluated. The data collected were tabulated and subjected to statistical analysis. Results and Conclusion: Evaluation of the clinical efficacy is relatively difficult because of the lack of appropriate measuring tool. In addition, choice of appropriate gingival retraction system is still a dilemma for the operator. Moreover, a particular clinical situation may indicate the specific technique.

Devvrat Singh, Sumita Giri Nishad, Mohit Sharma, Anurag Sareen
January-April 2014, 2(1):7-14
Precise marginal seating of fixed prosthesis over prepared abutments is crucial to fulfill biological, physical, and cosmetic requirements. Accurate fit of the restoration margins to the prepared finish line is necessary to prevent gingival inflammation, secondary caries acting as an important indicator of the overall acceptability of the cast restoration. The clinical success with porcelain fused to metal restorations lies in achieving both predictable esthetics and function. The design of the tooth preparation can have an effect upon laboratory and clinical success of individual restorations and types of restorations. The accuracy of casting holds the key to long-term success with these restoration. The presented literature review is an attempt to highlight the historical approaches, various pioneer researches, different controversies, difficulties, and current trends for casting of metal employing various techniques. A detailed literature search was conducted using MEDLINE/PubMed databases and other scholarly research bibliographic databases using Medical Subject Headings (MeSH). Studies describing research studies and in vitro studies were retrieved and evaluated from 1955-2013.

Shivani Kohli, Shekhar Bhatia, Shivani Kohli, Shekhar Bhatia
September-December 2013, 1(3):56-60
Although polymethylmethacrylate is the most commonly used denture base resin, its limitation of compromised flexibility has promoted the use of nylon-based denture resins. Aims: The purpose of this study is to evaluate and compare flexural strength and flexural modulus of two commercially available nylon-based flexible denture base materials, Valplast and Lucitone FRS, and injection-molded SR Ivocap polymethylmethacrylate denture base resin. Materials and Methods: A total of 15 samples of each group (Group A, B, C [Valplast, Lucitone FRS, SR Ivocap]) were prepared. All the samples were subjected to three-point bending test on an Instron Universal Testing machine to test their flexural strength and flexural modulus. Results: The results were statistically analyzed using SPSS Version 12. The difference in flexural modulus and flexural strength of all the three groups was statistically significant, P < 0.05. Conclusion: The mean flexural modulus of Valplast was significantly lower than Lucitone FRS, indicating that Valplast is less rigid, more flexible than Lucitone FRS, and hence more useful in conditions where flexibility in denture base is desired. SR Ivocap displayed flexural strength comparable with Lucitone, but less than Valplast.

Multidisciplinary approach in rehabilitating flabby ridge in completely edentulous patient
Poonam K Khinnavar, BH Dhanya Kumar, HR Shivakumar, DB Nandeeshwar
May-August 2015, 3(2):51-55
Hypermobile ridges or flabby edentulous ridges are a common occurrence. The mucostatic or minimally displacive impression technique is one of the treatment options in this scenario. Conventional mucostatic methods like employing a window tray technique, double spacers, multiple relief holes, can be utilized. Even the manual placement and manipulation of a custom tray may distort the tissues. This may violate the principles of mucostatic impression technique. Flabby ridges can be managed surgically by excision, ridge augmentation, injection of sclerosing solutions and also by implant retained prosthesis. Proper recording of these hypermobile tissues and stable occlusal contacts can help to manage flabby tissues to certain extent. This case report is about surgical and prosthodontic approach for management of a maxillary flabby edentulous ridge with the aid of a minimally displacive impression technique.

Gurminder Singh, Ramandeep Singh Gambhir, Rina Singh, Harpreet Kaur
January-April 2014, 2(1):23-27
Objectives: To know the various prosthodontic techniques followed by the private dental practitioners as compared withthe techniques taught to them in the dental schools. Materials and Methods: A survey was done to determine the prosthodontic techniques by private practitioners in India. A pretested questionnaire performa containing questions on complete denture, removable partial denture, and fixed partial denture fabrication was prepared for the private practitioners to be filled up. A total of 700 subjects were included in the final study (70% response rate). Results: A total of 80.4% of the practitioners used to do the whole prosthetic treatment themselves. A total of 61.7% used to make study casts before the treatment. And, 85% of the practitioners preferred to make complete dentures using double impression technique. Most practitioners faced problems during fabrication of complete dentures, removable partial denture, and fixed partial prosthesis. Conclusion: The findings from this study showed that the respondents did not follow the techniques and procedures which were being taught in the dental schools which had been deemed to be clinically essential for the successful prosthodontic treatment and there was a need for continuing dental education programs for the private practitioners for upgradation of their clinical skills.

September-December 2014, 2(3):82-85
Background: Removable partial denture (RPD) is a versatile, cost-effective, and reversible treatment method for replacing missing teeth in partially edentulous patients. It serves the purpose of improving patients' appearance, speech, mastication, confidence, and physchological well-being. Aims: Determining the patterns and reasons for demand of RPDs, including their relation to the socio-economic status among patients attending a teaching hospital dental center. Settings and Design: A retrospective study. Materials and Methods: Records of partial denture patients who attended the prosthetic dental clinic of the University College Hospital, Ibadan between January 2006 and December 2010 were retrieved. Information obtained included demographic data, occupation, and type of partial edentulous arch based on Kennedy classification. Statistical Analysis Used: Data were analyzed using SPSS version 20. Level of significance was set at P ≤ 0.05. Frequency and means were used for continuous variables, while Chi-square was used for categorical variables. Results: Nine hundred and sixty-three patients in the age range of 7-99 years and a mean of 45.1 ± 18.9 years were given RPDs during the period; 37% of the patients were young adults (21-40 years), 51.7% were male, and 31.9% were civil servants. Aesthetics was the main reason (60.2%) for seeking RPD and was statistically significant in relation to age group (P = 0.00). Majority [525 (54.5%)] demanded for maxillary RPD. There was increase in demand for both upper and lower dentures among the older age groups (P = 0.00). Majority (56.9%) of the dentures demanded were for Kennedy class III edentulous arches. Conclusions: Kennedy class III dentures were the highest in demand than any other class both in the maxilla and mandible, and the main reason for RPDs was aesthetics.

Repair of porcelain restorations: Four case reports
Hasan Hüseyin Kocaagaoglu
May-August 2015, 3(2):42-46
Porcelain has been used with prosthetic restorations for many years. Although their long term success has been demonstrated, failures may occur in metal-porcelain restorations due to trauma, laboratory failures or premature contacts. Damaged porcelain restorations can cause serious clinical and esthetic problems. In some situations, the production of a new restoration is difficult because of the high treatment costs. Porcelain repair may provide a practical alternative for patients and clinicians, especially those restorations with minor porcelain cracks. In the present series of case reports, repair of the fractured metal-porcelain restorations, using porcelain repair system and composite resin were demonstrated.

Platform switching: A step away from the gap
Shefali Singla, Manu Rathee, Lalit Kumar, Mili Gupta
January-April 2015, 3(1):1-9
To maintain long-term stability of dental implants, it is important to minimize bone loss around an implant. Several clinical studies have shown a mean crestal bone loss of 1.5-2 mm around dental implants, in the first year after prosthetic restoration, as clinically acceptable. To limit this crestal bone resorption, several modifications are being tried in the implant systems. Platform Switching is one such concept, which uses prosthetic abutments with reduced diameter in relation to the implant platform diameter. This moves the implant abutment junction and supposedly the inflammatory reaction medially, away from the crestal bone, and may thus, minimize the crestal bone loss. Although, it was a serendipitous finding, an increasing number of implant systems have incorporated Platform Switching into their designs, as an innovative feature for preserving the peri-implant bone. A Medline search was carried out using the Pubmed search engine, with keywords Platform Switching in Dental Implants. Twenty-one studies (12 random-controlled trials, fourprospective-controlled clinical studies, and five clinical case series) were selected for review after screening of a total of 123 articles on the basis of the inclusion and exclusion criteria. A detailed review of these articles gave a clear tendency toward the positive impact of Platform Switching on crestal bone preservation, but further long-term, randomized-controlled trials, with uniform criteria, are required to confirm these results.

Rehabilitation of a partial maxillary defect with magnet retained two-piece hollow bulb obturator
Suryakant C Deogade, Sneha S Mantri
May-August 2014, 2(2):62-66
A restricted mouth opening in hemimaxillectomy patients can create a significant problem with insertion and removal of the obturator prosthesis. A two-piece obturator is an alternative management for such patients. The treatment of a patient with a hemimaxillectomy due to squamous cell carcinoma is presented in this clinical report. A sectional obturator prosthesis retained by magnets was fabricated to deal with trismus, fibrosis, and microstomia. The patient's esthetic and functional expectations were satisfied. The new generation of magnets with improved technology provides sufficient denture retention for clinical application. However, further follow-up may be necessary to ascertain the long-term usefulness of the magnet-retained obturator prosthesis, because of corrosion and further loss of magnetism.

September-December 2015, 3(3):64-70
Context: The rapid provision of high.quality complete dentures is an unmet clinical need in some populations. Novel procedures may simplify this service but require validation against existing methods. Aims: The aim of this trial was to evaluate the clinical acceptability of complete dentures fabricated using the biofunctional prosthetic system. (BPS) when compared with conventional methods. Materials and Methods: This study was designed as a crossover trial. The patients wore either a complete denture, which was made using the biofunctional prosthetic system biofunctional prosthetic system complete denture (BPSCD) or a complete denture made with conventional procedures conventional complete denture (CCD) for 3. months before switching to the other dentures. The patients were asked to report their satisfaction levels in an abbreviated version of the Oral Health.Related Quality of Life questionnaire, specifically designed for edentulous patients. (Oral Health Impact Profile for edentulous subjects. [OHIP-EDENT]). Furthermore, the number of adjustments required for each technique to deliver pain.free fitting was noted. Finally, the patients were asked to state which denture gave them superior occlusal feel, comfort, esthetics, and retention and which denture they wished to keep for the long-term. Results: Although the satisfaction score and the OHIP.-EDENT scores showed no significant differences, the majority of patients preferred the BPSCD over the CCD in terms of occlusal feel, comfort, esthetics, and retention. Nine out of 10 patients chose to keep the BPSCD rather than the CCD, with one patient choosing the CCD for purely esthetic reasons. Conclusions: Within the limitation of this study, the BPS produced high.quality complete dentures with satisfactory results and was just as efficient as conventional procedures.

Ozlem Kara, Necla Demir, A Nilgun Ozturk, Mustafa Keskin
January-April 2015, 3(1):23-25
Malignant tumors of the nose occasionally require rhinectomy. Facial defects can cause not only functional problems but also some serious physchological problems that could cause the individual to avoid social contact. In view of this, the first aim of maxillofacial rehabilitation should be solving esthetic problems. Implant retained prostheses can give good esthetic results. Predictable biomechanical retention of nasal prostheses can be achieved using osseointegrated implants and intra-oral and craniofacial implants have been used previously. These prostheses are tissue compatible, simple in design and easy to place, can be worn independently of spectacles and in the majority of cases can be provided soon after surgical excision. In this case report, a nasal prosthesis was fabricated for a patient who lost his nose due to the basal cell carcinoma. Extra-oral implants and magnet retention for the proper connection of the nasal prosthesis were used. This prosthesis was acceptable for the patient because of excellent support, retentive abilities and the patient's appearance.
