Peri-implant bone loss around platform-switched Morse taper connection implants: a prospective 60-month follow-up study

The aim of this study was to measure the crestal bone level changes at 60 months of follow-up and to evaluate the influence of biologically relevant, anatomical, and implant-related variables. A prospective study design was used. STROBE guidelines were followed. A total of 576 implants were inserted in 270 patients needing an implant-supported, partial, fixed dental prosthesis or a single crown. Standardized peri-apical radiographs were obtained at 2 months (time of implant–abutment connection and prosthetic loading) and 60 months of follow-up.
