A nice beginning to end documentation of a standard maxillary molar case. Very standard. We always use a CT to verify bone depths. This case was done flapless because of the great bone dimensions. I try to always use a screw retained prosthesis now because its so easy to restore. No cement. No cleanup. Plus no need to temporize. Just take an open tray impression then place the healing abutments back into place and wait a week for the lab to fabricate the restoration. The one drawback is the contacts must be perfect. There is no margin for space or error in screw retained contacts as parallelism is a must. In my earliest cases I didn’t realize this. Now you need to make sure you communicate with the lab to perfect your contacts. Or you will do alot of chairside adjusting. Cement retained obviously can get away with imperfection but you know if you have less that perfect contacts on a implant cement restoration, you have an open margin somewhere. Also I find capturing the margin tough on implant impressions for cement retained abutments because the gingival height varies so much. I place implants slightly sub-crestal so its tough. Srew retained eliminates all that hassle.
