The bone lid technique in lateral sinus lift: a systematic review and meta-analysis

Abstract

Objective This systematic review aimed at assessing the effect of the repositioned bone lid on bone augmentation in lateral sinus lift in pre-clinical in vivo and clinical studies. Secondary aims were to report on the healing of the bone window and to assess the implant survival rate. Material and methods Animal and human studies comparing lateral maxillary sinus floor elevation in combination or not with the repositioned bone lid were retrieved from MEDLINE (PubMed), Web of Science and Cochrane online library. Studies published in English up to April 2022 and reporting on histological and/or radiographic outcomes were considered. Case reports, case series and reviews were excluded. A hand search was also conducted. Risk of bias was assessed and meta-analysis performed to investigate the effect of the bone lid on new bone formation. Results After screening, 5 animal studies (4 in rabbits, 1 in sheep) and 2 clinical studies (1 RCT, 1 case–control) were included. Meta-analysis confirmed a higher new bone formation in rabbits at 2 and 8 weeks using the bone lid. The two clinical studies investigated lateral sinus lift with concomitant implant placement and reported similar results and high short-term implant success rate in both test and control groups. Conclusions The meta-analysis provided moderate evidence that the repositioned bone lid favored the formation of new bone to a higher extent as compared to resorbable membranes in animal studies. Implant success seems not to be influenced by the technique in the short term.

Simultaneous placement of short implants (≤ 8 mm) versus standard length implants (≥ 10 mm) after sinus floor elevation in atrophic posterior maxillae: a systematic review and meta-analysis

“…After tooth loss, alveolar ridge resorption and maxillary sinus pneumatization result in poor bone quality and insufficient residual bone height (RBH) in the posterior maxilla [1]. When placing standard implants directly in an atrophic posterior maxilla, maxillary sinus floor elevation (SFE) was routinely used to increase bone volume [2]. Standard implants placed after SFE can achieve a high implant survival rate (94-100%) [3][4][5].…”

Is one-stage lateral sinus lift and implantation safe in severely atrophic maxillae? Results of a comparative pilot study

“…All biomaterials used in this study are well-documented in the current literature and have multiple applications in oral surgery [ 24 ], but the application of a one-stage lateral sinus lifting approach with simultaneous implantation for cases with a residual crestal bone height of less than 3 mm has been less investigated. A recent meta-analysis provided moderate evidence that the repositioned bone lid favored the formation of new bone to a higher extent as compared to resorbable membranes [ 25 ]. Another solution for limited alveolar bone heights is the usage of short implants.…”
