The objective of this study is to evaluate installed implants survival in maxillary sinus lift surgeries after 24 months of function. Twenty-eight maxillary sinus lift were performed using resorbable synthetic hydroxyapatite (Osteogen®) as filling material. In these reconstructions, 48 implants were installed, 23 at the time of reconstruction (Group 1) and 25 implants, 5 months after grafting (Group 2). The mean vertical bone increase was 8.01mm in Group 1 and 9.15mm in Group 2. After 24 months control, only one implant was lost in Group 2 and no one in Group 1. Installed implants survival index in maxillary sinus lift after 24 months of function was 97.91%.
