LEIGHTON, Y et al. Prosthetic protocol - surgery in the immediate temporization of a single tooth using a multifunctional removable tray. Rev. Clin. Periodoncia Implantol. Rehabil. Oral [online]. 2010, vol.3, n.1, pp. 34-38. ISSN 0719-0107. doi: 10.4067/S0719-01072010000100006.
Purpose: This clinical report is the description of a prosthetic protocol - surgery which allows direct visualization of the operative site and the correct positioning of the prosthetic-implantation of a screw retained temporary crown constructed immediately following the insertion of the implant. Methods: 10 patients, whose main inclusion criterion was having a partially edentulous posterior unit with an opposing natural tooth, were selected from the specialized program of Maxillofacial Implantology at the University of Chile. As diagnostic protocol was requested, laboratory tests, radiographic examinations and impressions of dental arches were recorded in order to obtain plaster models for the study and which were positioned in a semi-adjustable articulator type Whip Mix, which produced a diagnostic wax-up tooth replacement, free of occlusal contact in the maximal intercuspal (MIC) and mandibular excursions. Based on the diagnostic wax-up one can design a multi-functional removable tray (U. de Chile), whose key feature is that it merges a surgical guide and a prosthetic assembly guide for the correct immediate temporization. The procedure starts with a full thickness flap positioned in the mouth of the multi-functional guide of the surgical phase to allow the implant site drilling and implant insertion. The surgical site is sutured with black braided silk and you immediately draw up the screw retained temporary crown using the multi-functional guide in the prosthetic loading phase. Results: A total of 12 Renova Tapered implants (Lifecore) were installed using the multi-functional tray which provided the direction of the drilling and construction of its acrylic- resin temporary crowns without segmented screws. Conclusions: With the limitations of this study, the merging of both procedures provide a predictable safe alternative treatment that is quick and easy to implement for the clinician allowing the immediate temporization of the implant.
