A New Method for Achieving Passive Fit of an Interim Restoration Supported by Brånemark Implants: A Technical Note

When carrying out restorations supported by dental implants, it is advisable to have a temporary method that offers the possibility of evaluating and/or creating a proper emergence profile, peri-implant health, occlusion, esthetics, acceptable phonetic response, and hygiene, as well as one that facilitates progressive loading of the implants during the bone maturation period. To maintain osseointegration it is essential that a prosthesis fit with total passivity, since the lack of a periodontal ligament renders the implant unable to modify its position. Gold cylinders for EsthetiCone abutments, which were modified following a previously reported technique, were used so that provisional prostheses could be fixed to the cylinders in the mouth by means of an alternative cementing technique. By this way, a provisional prosthesis with total circumferential fit, maintaining the option of retrieval, could be routinely obtained. Keywords: interim prostheses, osseointegration, passive fit
