A method for fabrication of extraoral verification template for implant master cast
An accurate intraoral impression of the 3-dimensional position of dental implants and peri-implant tissues is essential when fabricating an implant-supported fixed dental prosthesis. It is equally important to transfer this information precisely to the definitive cast.1,2 Different impression transfer techniques for implant-supported restorations, including splinting impression copings, surface treatment of impression copings, direct or indirect impression techniques, and different impression materials, are available.A cost-effective and straightforward technique to fabricate an intraoral photographic contraster
Dental photography is a routine procedure in contemporary dental practice.1 A photographic black contraster is a tool for dental photography that provides a black background to isolate the teeth of interest. The black color neutralizes the background, making it easier to visualize color matches or mismatches.2 Digital photographs aid in transferring information about shade, enamel staining, characterization, and incisal edge translucency between the dentist and the dental laboratory technician.3 High-quality images can impress patients and can be used for professional instruction and publications.Accurate repositioning of an implant interim restoration into the definitive impression to obtain an exact reproduction of tissue contours in the soft tissue cast
Detailed reproduction of the soft tissue surrounding the implant is essential to the passive fit of implant restorations, and even small discrepancies may result in complications during the fabrication and insertion of the definitive crown. A method is presented here for transferring precise tissue contours to the definitive cast by using the interim restoration as an impression coping, simultaneously helping to mold the peri-implant tissue.1,2 Soft tissue becomes modifiable after controlled and constant compression.Fabricating short-term interim restorations from edentulous tissue conditioner material
The fabrication of interim restorations is a critical step in fixed prosthodontic treatment.1,2 In an extensive treatment, creating proper margins and adequate emergence profiles requires time and precision.3,4 However, if a rehabilitation appointment needs to be shortened unexpectedly and the relined interim shell still needs to be refined, the use of a short-term interim restoration is convenient for both the patient and clinician. This article describes a technique for fabricating a rapid and esthetic short-term interim device from a tissue conditioner and a vacuum-formed matrix.
