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 self-grinding occlusal plane template to help modify an uneven occlusal plane before providing definitive restorations
Uneven alignment of the natural teeth is a common clinical occurrence, which may be caused by eruption, wear, or drifting of teeth.1 A normal occlusal plane, such as with a curve of Monson,2,3 is a primary objective of restorative procedures and facilitates natural mandibular movements and mastication.1 Devices and techniques have been described to evaluate and correct the occlusal plane, including the Broderick occlusal plane analyzer,4 the Yurkstas metal occlusal template,5 and the custom made occlusal plane template (OPT).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.Alternative technique for handling indirect restorations during evaluation and cementation
Inlays, onlays, and porcelain veneers are small, fragile, and prone to accidental swallowing by the patient during the evaluation or cementation procedure.1 Evaluation of restoration fit and restoration placement also are challenging tasks.2 Once these restorations are fitted into the cavity preparation, they may be difficult to remove, especially class I inlays. Some clinicians have advocated special carrying devices (Optrastick; Ivoclar Vivadent), sticky wax, or dental adhesive.3,4 An alternative technique for handling the restorations with the help of a microbrush tip and composite resin is proposed.A radiographic measurement technique for crest bone changes related to dental implants
The evaluation of crestal bone loss to assess implant success rate with radiographs and/or computerized tomography scans has been well described.1 After implant placement and at subsequent recall appointments, clinicians typically make an intraoral periapical radiograph. However, at each appointment, there are changes in the radiographic image.2,3 Conventionally, the distance between the first screw thread to the top of the alveolar crest in the parallel periapical radiograph is measured to assess crestal bone changes.
