Implant Provisional Fixed Partial Denture: Any Advice?

Dr AJK You did not mention whether the provisional resin fixed partial denture was going to be placed after the implants osseointegrated or after the implants were placed and immediately temporized. Do not be concerned about damaging the threads in the situation you describe, because neither hand tightening nor torquing to 15 Ncm is enough to damage threads. Measuring the torque with a torque wrench while tightening screws or while placing implants is always a good idea. Tightening the screws without properly engaging the threads is more likely to be the cause of damaged threads. In that area of the mouth, the implants are subjected to lateral, off-angle loads and depending on the particular situation in your patient's case such as the size and length of the implants planned, grinding or clenching habits, inclination of the incisors, interincisal angle, etc.. you may want to consider an additional implant in one of the central positions. Good luck.

One more thing. Also make sure the case has posterior teeth in occlusion for adequate posterior support, or the forces while functioning may make the case fail prematurely. Thanks for posting.

The implants were placed 8 months ago. 4&6 11& 12 teeth are present and they will be crowned ( eMax). In addition to mentioned above implants Noble biocare 7&10, I will be restoring 13, 14,15 ,3 and 4. My plan was to temporize 4 6,11 12 and implant bridge and after that the posterior segments in couple months. The Tx will be split due to financial consideration. Any advice on this case? Will be enough of support for posterior occlusion on these existing teeth?

Dr AJK If there is a similar complement of posterior teeth in the mandible, and both upper and lower posteriors have stable periodontal status, sounds like you have enough posterior support.
