Marginal bone loss around mandibular implant-retaining overdentures versus implant supported fixed hybrid prosthesis: A 5-year follow-up.

Description :

After having determined the size of the sample and the number of subjects necessary in each group according to the prosthetic treatment undergone, the patients having undergone one of the 2 treatments and having a post-loading retro-alveolar X-ray will be called for a control visit in order to assess peri-implant health, and peri-implant bone loss clinically and radiologically. Once the 2 X-rays available, a comparison of the bone level can be carried out and the statistical study established.
