However, both the techniques require Dr. Vikram Jay. The importance of provisional restorations as an integral part of fixed prosthodontic treatment is evident from the abundance of the literature pertaining to their importance regarding margin fidelity, function, occlusion, and esthetics. Direct methods are often very quick to implement, but a number of studies have shown better quality of restoration by indirect methods: It is known that fabricating provisional crowns by the indirect technique produces more acceptable marginal adaptation than do other techniques. The provisional restoration should be an intra-oral prototype for the proposed restoration. The fabrication of properly contoured, well‐fitting provisional restorations is paramount to the success of the definitive restoration and ultimately to the overall treatment. The plastic crown was attached to the sprue-former and invested. Mix putty and fabricate matrix. OBJECTIVES: a. INTRODUCTION. Sign In; Create an Account "Never doubt that a small group of thoughtful, committed citizens can change the world. The full-contour restoration was then placed over the coping to verify the fit. The fabrication of a single-tooth implant supported restoration requires careful step-by-step approach in order to deliver a restoration that will assist the process of soft tissue sculpting. A provisional restoration that is made outside a patient's mouth with the IWDT can satisfy all biologic, mechanical, and esthetic requirements, and can be constructed with the use of accurate, flexible, elastomeric dies. Previous techniques for provisional fabrication include development of a stint from a wax-up where the stint is filled with a material, such as bisacryl6, and seated in the mouth. A technique is presented to illustrate a simple and reliable method to provisionally restore a single tooth restoration. Fabrication of a fixed provisional restoration A variety of materials and procedures have been used in the fabrication of fixed provisional restorations. In addition, the provisional can be modified until the patient is satisfied, and then the modified provisional restoration serves as the blueprint for the technician. place provisional restoration and subsequently replace it with permanent restoration. Provisional restorations can be placed and readily modified after tooth preparation but before fabrication of the definitive restoration. Fill putty matrix with Protemp, place onto typodont tooth, and remove putty matrix. * The provisional restoration can be relined intraorally with the patient in centric occlusion, thereby minimizing the amount of occlusal adjustment necessary Several techniques for this method of provisional fabrication are presented below. A properly fabricated provisional restoration is important in achieving a successful indirect restoration. Prepare and dispense Protemp provisional material. Fabricate provisional restoration using direct technique. The technique involves fabrication of the interim restoration outside the mouth. 1 Provisional restorations serve to maintain vertical dimension of occlusion, to maintain positional stability of the prepared teeth, and to reestablish or preserve proper anterior guidance. Several laboratory and clinical techniques for the fabrication of provisional restorations have been described in the literature, such as the indirect technique, direct technique, and indirect-direct techniques for both single and multiple unit restorations.
