Resumen:
Introduction: The aim of this retrospective study was to analyze the radiographic periimplant bone loss of bone level implants and tissue level implants with a convergent neck in
screw-retained single crowns and in screw-retained fixed partial prostheses, after two years of
functional loading. Materials and methods: The sample was divided into two groups according
to their type: Group I: supracrestal implants with convergent transmucosal neck; Group II: crestal
implants. In each group we distinguish two subgroups according to the type of prosthetic restoration:
single crowns and a three-piece fixed partial prosthesis on two implants. To quantify bone loss,
parallelized periapical radiographs were analyzed at the time of implant placement and after two
years of functional load. Results: A total of 120 implants were placed in 53 patients. After statistical
analysis it was observed that for each type of implant bone loss was 0.97 ± 0.91 mm for bone level
and 0.31 ± 0.48 mm for tissue level. No significant differences were found regarding the type of
prosthesis and the location (maxilla or mandible) of the implants. Conclusions: Tissue level implants
with a convergent transepithelial neck exhibit less peri-implant bone loss than bone level implants
regardless of the type of prosthesis.
