Techniques to facilitate provisionalization of implant restorations

Purpose: The aim of this article was to review current methods for immediate provisionalization of single unit implant restorations. Methods: Four methods are discussed and illustrated in detail, including: preoperative preparation of an abutment and provisional crown using diagnostic models; abutment placement and modification at the time of implant placement; the use of 1-piece or non-prepable abutments; and methods of indexing. Material characteristics for indexing are presented to provide the clinician with an understanding of material handling in relation to accuracy of indexing. Conclusion: Depending on clinician and patient case specific criteria, immediate provisionalization of implant restorations can be performed in an efficient manner.
