Resumo
Background: The osteotome maxillary sinus floor elevation technique (OSFE) consists in the realization of a bed at the top of the ocean where the Schneider’s membrane is detached and raised using the osteotomes in order to place implants in a lesser invasive manner, reducing the time of surgery and reducing postoperative discomfort. There are different factors when performing the technique, such as the amount of residual bone that has the maximum flow type or the type of injection that will be placed in the breast. The main objective is to evaluate the survival rate of implants placed simultaneously in atrophic maxillae of ≤ 5 mm RBH (residual bone) and without graft placement in the sinus cavity. Material and methods: The study consists of a systematic review approach on the performance of crestal elevations ≤ 5 mm of residual bone without the use of grafts. This analysis is based on 7 studies, 2 RCT (randomized clinical trials), 3 retrospective studies and 2 prospective studies. Results: There were 24 implants lost, 17 in the short-term (prior to a year) from the 379 implants placed. Obtaining survival rates of between 91.4% to 100% for the cases analyzed. The marginal bone loss of the injected group and non-injected group was similar. Sinus bone gain was greater in the group that participated in the non-graft group. Conclusions: The survival rate of crestal elevations with the simultaneous placement of implants ≤ 5 mm of residual bone was a safe and effective work, although greater detailed investigations are required.
