Fabrication of a single complete denture opposite natural dentition is a common practice in general dentistry. Patients undergoing extraction of all teeth of a single arch experience a lot of discomforts while eating, speaking, and swallowing due to impingement of teeth on the mucosa adjacent to fresh extraction sockets. To avoid this, we advocate fabrication of a immediate ridge guard using Sof-Tray sheets (Ultradent Products, Inc.). The sheets are available in various thicknesses and 6 square inch form. A 2 mm thick sheet is optimum for fabricating a ridge guard since 1 mm thick sheet is sharp and thicker sheets (3 and 4 mm) are harder and used to fabricate mouth guards and occlusal splints [Figure 1].{Figure 1}


The process of thermoforming involves the placement of the sheet in a clamping frame of a vacuum forming machine (UltraVac vacuum former/Accuvac). The cast is placed underneath it and over the vacuum plate. The sheet starts sagging towards the cast by the heat conducted from the heating element when the unit is switched on. When the sheet comes closer to the edentulous cast, the clamping frame is lowered manually, and the vacuum is activated simultaneously to ensure good adaptation. The material is allowed to cool to room temperature. It is subsequently trimmed to the desired extension with sharp scissors. The edges of the ridge guard are smoothened by slight flaming using micro torch.[1]

Apart from preventing trauma, ridge guard prevents food lodgment in the extraction sockets [Figure 2]. The ridge guard functions similar to an immediate denture with a soft lining and acts as a splint covering the edentulous area. The material is inert and has been used for fabrication of bleaching trays, soft splints, and night guards since decades.[2] Due to its transparent nature, it does not compromise on esthetics, and hence can be worn during the daytime. This appliance should be worn during the transitional period between extraction and denture fabrication, which usually ranges between 2 and 3 months. Since the guard is constructed in a thermoplastic material (ethyl vinyl acetate), patients should be instructed not to eat or drink very hot food to avoid deformation of the guard.{Figure 2}
