Outcomes of implants placed after osteotome sinus floor elevation without bone grafts: a systematic review and meta-analysis of single-arm studies

Abstract

Background The aim of this study is to evaluate the implant survival/success rate, gain in alveolar bone height, crestal bone loss, and complications associated with implants placed in the posterior maxilla after osteotome sinus floor elevation without bone substitutes. Methods The electronic databases, such as MEDLINE, EMBASE, CENTRAL, and SCOPUS were systematically and manually searched for publications in peer-reviewed journals. The included articles were subjected to qualitative and quantitative analyses, and the meta-analysis was carried out for single-arm studies. Methodological quality assessment was made for all the included studies. Results The included studies were of moderate quality, with the overall implant success and survival rates of 98.3% and 97.9% respectively. The most frequent intra-surgical complication was sinus membrane perforation, accounting for 3.08% of the total implants with reported perforations. The overall crestal bone loss in patients with immediate implants placed with OSFE after a 5-year follow-up was 0.957 mm 95%CI (0.538, 1.377). Conclusion Within the limitations of this review, it can be concluded that the survival and success rates of implants placed immediately along with OSFE without any bone substitutes are acceptable and show adequate implant stability with less crestal bone loss over 5 years.

Clinical efficacy of transcrestal sinus floor augmentation, in comparison with lateral approach, in sites with residual bone height ≤6 mm: A systematic review and meta‐analysis

“…The meta‐analysis showed a high implant survival rate in TSFA procedures. The results of this paper were quite close to previous systematic reviews (Călin et al, 2014; Ye et al, 2021), which showed the overall implant survival of 96.15%–97.9%. But those described the comparison without regard to the RBH, which was different form the present review.…”

Osseointegration at Implants Installed in Composite Bone: A Randomized Clinical Trial on Sinus Floor Elevation

“…Sinus floor elevation through a lateral access is a well-documented procedure used to increase bone volume in the posterior segments of the maxilla [ 1 ]. This approach includes the elevation of the sinus mucosa and the immediate placement of biomaterial [ 2 , 3 ], devices [ 4 , 5 , 6 ], implants alone [ 7 , 8 ], or in conjunction with biomaterial [ 9 ], aiming to maintain over time the elevated volume and allow bone growth within the subantral space [ 10 , 11 , 12 , 13 , 14 ]. The use of a membrane to cover the lateral bone window has been suggested to improve implant success [ 1 ] and might decrease both the dislodgment of the biomaterial through the access window [ 15 , 16 ] and the post-surgical morbidity [ 16 ].…”

Dental Implants in People with Osteogenesis Imperfecta: A Systematic Review

“…Although sinus floor elevation and ridge augmentation are now standardized procedures when insufficient bone is available prior to implant placement, the present study provided little information on these procedures in an OI population [45][46][47][48]. Sinus elevation was performed in 19 implants prior to implant placement and ridge augmentation was reported for 30 implants.…”
