Modified clear silicone index for light-polymerizing direct composite resin restorations
Light-polymerizing composite resins have been commonly used to restore the esthetics and function of anterior and posterior teeth1,2 Creating an ideal tooth morphology with direct composite resin is challenging, time consuming, and requires artistic skill, especially when multiple teeth are being restored. The procedure is simplified with the use of an index.3 Conventionally, a putty elastomeric impression material is adapted to a waxed cast to fabricate an index.3 However, light cannot pass through the opaque material.A technique for registering the peri-implant soft-tissue profile with an interim restoration
Creation of a pleasing peri-implant soft-tissue architecture in an esthetic zone is a challenging task. To develop a predictable gingival architecture during the healing process, the contours of the implant-supported fixed interim restoration requires careful modification.1 Once an appropriate gingival profile has been achieved, it must be recorded in the definitive impression. Different techniques have been proposed to replicate the peri-implant soft-tissue profile by using a custom impression coping,2 by inserting autopolymerizing acrylic resin into the sulcus,3,4 and by using an interim restoration transfer protocol.
