ORIGINAL ARTICLE
Flexural properties of polyamide versus injection-molded polymethylmethacrylate denture base materials
Shivani Kohli, Shekhar Bhatia, Shivani Kohli, Shekhar Bhatia

DOI:10.4103/2347-4610.119792  
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.

Case report of a 70-year-old female patient showing the effective rehabilitation of function and esthetics with the help of a fixed bridge in which an autotransplanted tooth was used as abutment in the upper arch. The case report emphasizes the possibility of using autotransplants - in geriatric patients; and - as an abutment for fixed prosthesis in rehabilitating occlusion.

Prosthodontic management of microstomia employing sectional impression tray
Sukant Sahoo, Suraj Suvarna, NS Vineeth, Prince Kumar, Sukant Sahoo, Suraj Suvarna, NS Vineeth, Prince Kumar

Prosthetic rehabilitation of microstomia patients presents difficulties at all stages as the maximal oral opening is smaller than the size of a complete denture. Such a condition may often result from the surgical treatment of orofacial cancer, cleft lip, trauma, burns, Plummer-Vinson syndrome or scleroderma. Microstomia frequently leads to several incapacitating sequelae such as the inability to masticate, speech problems, impaired delivery of oral hygiene or dental care, and psychological problems secondary to facial disfigurement. Several techniques have been described to use when either standard impression trays or the denture itself becomes too difficult to place and remove from the mouth. This article focuses on a novel fabrication of maxillary sectional trays that could enable easier and competent impression making in a patient with limited oral opening.

Myths about prosthodontics
Sagar J Abichandani, Sagar J Abichandani
September-December 2013, 1(3):49-55

Prosthodontics like many other clinical procedures lacks support of good evidence. The main aim of this paper is to check current evidence for selected procedures. A MEDLINE/PubMed search was conducted for articles on the selected items. Many opinions are based more on belief rather than scientific evidence; hence, many "old truths" regarding prosthodontic interventions can be called dogmas. Many common clinical procedures lack scientific support; this is one of the observations revealed while inspecting prosthodontic literature.
