To compare the relative efficacy of different cooling techniques which can be used during direct fabrication of provisional restorations. Trim, polish, and evaluate provisional restoration. The standard procedure of fabrication of Implant supported provisional restoration is by using either temporary abutments or copings [1]. To evaluate, if … Because of these disadvantages with manufacturer's protective cap, provisional restorations for ITI solid abutments have been fabricated by alternative techniques, such as modifications of burn out coping, resin coping, impression cap, and protective cap.3,4  Many techniques advocate the chair side fabrication of provisional restorations. Prepare and dispense Protemp provisional material. This phase of restorative treatment should not be merely considered a temporary treatment but as a template for the ensuing prosthesis. Once the material reaches an initial set, the matrix can be removed. place provisional restoration and subsequently replace it with permanent restoration. The full-contour restoration was then placed over the coping to verify the fit. The provisional restoration must fit and be contoured to allow for tissue healing and optimal contour formation. Sign In; Create an Account "Never doubt that a small group of thoughtful, committed citizens can change the world. The IWDT can be used to fabricate provisional restorations in advance of a patient's dental appointment. The provisional restoration should be an intra-oral prototype for the proposed restoration. Provisional restorations can be placed and readily modified after tooth preparation but before fabrication of the definitive restoration. However, both the techniques require Dr. Vikram Jay. Patients and methods. [4] Lewinstein I, Chweidan H, Matalon S, Pilo R. Retention and marginal leakage of provisional crowns cemented with provisional cements enriched with chlorhexidine diacetate.
