The objective of this study was to establish the frequency of intraoral imaging at the time of insertion of implant supported restorations at University of Louisville School of Dentistry (ULSD). After IRB approval (14.1215), patients on whom an implant-supported single unit fixed restoration was placed were identified from the electronic health record over a 4-year period. Type of prosthesis retention (cement vs. screw) and discipline responsible for crown placement was recorded. Bitewing (BWx) or periapical (pa) images taken at the time of prosthesis placement were accessed and reviewed. Overall radiographic frequency according to modality was tallied and compared using Chi-square (p ≤ 0.05). 269 patients had 425 implants restored with single unit crowns (74% cement retained, 26% screw retained). Only 61% (259) of implants had images taken at the time of prosthesis placement. More implants had a pa image (38% [163]) than BWx image (23% [96]) at the time of crown delivery (X2=42.03, p2=27.75, p2=6.45, p=0.01). More than 1/3rd of implant supported restorations are not imaged at the time of insertion. Both BWx and pa radiography is used to image crown placement. A greater percentage of cement retained prosthesis were imaged at time of insertion compared to screw retained. Specific imaging protocols should be implemented across disciplines to standardize teaching strategies for clinical faculty and to ensure quality control.
