Different impression techniques have been given in literature for the fabrication of ocular prosthesis. An accurate impression is required for the perfect fitting of the prosthesis. This article describes a modified impression with the help of dispensing gun with simple, accurate and time saving technique.
Keywords: Custom tray, eye prosthesis, orbital impression

Various impression techniques had been suggested for making the ocular impressions. Brown  suggested syringe technique and Jethwani et al. suggested hollow handle technique for making impression, but drawback with this techniques was that the impression materials had to be loaded in the syringe before making impression. This article describes a simple, accurate, and time-saving technique, where the impression can be made directly with the dispensing gun using mixing tip without the need of attaching and loading the syringe.
| Procedure|| |
- Make the primary impression of the defect with putty consistency addition silicone (Reprosil, Dentsply, Milford, USA) impression material, and pour the impression with type II dental plaster (Kalabhai, Mumbai, Maharashtra, India)
- Fabricate the special tray with cold cure clear acrylic resin (DPI, Mumbai, India) and make escape vents for the escapement of excess impression material
- Attach a mixing tip (Reprosil, Dentsply, Milford, USA) to the special tray [Figure 1]a
- Place the special tray in the ocular socket for making the final impression of the ocular defect. Connect the dispensing gun (Heraeus Kulzer, Dormagen, Switzerland) to the mixing tip attached to special tray and inject the impression material (Regular viscosity addition silicone, Reprosil, Dentsply, Milford, USA) [Figure 1]b
- The patient was instructed to do ocular movements to get functional impression of the socket. Removed the impression and checked for its accuracy [Figure 2].
