“…In our study, no postoperative complications were observed resulting from the perforated Schneiderian membrane. This was in line with a previous meta‐analysis that refuted the “panic” over membrane perforation (Díaz‐Olivares et al, 2021). A total of 1598 MSFA operations were included, and the perforation group had no statistically significant lower implant survival rate.…”

Objectives: To retrospectively compare multilevel volumetric changes in both hard and soft tissues between antral pseudocyst (AP) removal and retainment before maxillary sinus floor augmentation (MSFA) and immediate implant placement. Material and methods:Twenty-six patients with 38 implants placed from 2016 to 2021 were included and divided according to a cohort design as follows: 13 removing the cyst (RC group) and 13 "leaving alone" the cyst (LC group). 3D radiographic parameters (primary outcome), 2D parameters and clinical records (secondary outcome) involving both hard and soft tissues were evaluated for four periods (T1: immediate postoperative, T2: 6-month, T3: 12-month, and T4: 2-to 5-year follow-up). Possible confounding factors, including sinus anatomical features and implant distribution, were also analyzed to eliminate their disturbance. Results:The 3D volumetric change rate of bone grafts in the RC group (−9.32% ± 10.01%) from T2 to T3 was significantly lower than that in the LC group (−19.8% ± 10.59%) (p < .05). The change rate of apical bone height (ABH), endo-sinus bone gain (ESBG) and other 2D parameters were not significantly different between the two groups.5.3% implants in RC group and 9.1% implants in LC group failed during follow-ups. 0% postoperative complications were observed in RC group. The Schneiderian membrane of RC group was significantly thinner than that of LC group at two measuring points in sinus. Conclusion:The present study demonstrated that compared to AP retainment, AP removal before MSFA and immediate implant placement can obtain higher bone graft volumetric stability and favorable prognosis.

“…Another retrospective study demonstrated that the implant survival rate in the perforation and non-perforation groups were 100% and 95.5%, respectively [ 54 ]. The review of Díaz-Olivares LA et al reported that there was no significant difference in implant survival rate between the perforation group (97.68%) and non-perforation group (98.88%) ( p = 0.229) with appropriate management to perforation [ 55 ]. Perforation might not affect implant survival rate but it could cause postoperative complications [ 46 , 56 ].…”

Purpose The objective of this meta-analysis was to compare the clinical outcomes of using short implants (≤ 8 mm) inserted with osteotome sinus floor elevation (OSFE) and standard implants (≥ 10 mm) inserted with sinus floor elevation (SFE) in atrophic posterior maxillae with insufficient residual bone height (RBH). Methods An electronic search was performed on PubMed, EMBASE, and the Cochrane Library from 1994 to July 2022, in combination with a manual search of references in relevant articles. Randomized controlled trials (RCTs) that compared the clinical results between short and standard implant placement with SFE were included. The primary outcomes were implant survival rate and marginal bone loss (MBL); the secondary outcome was complication rate. Results Three RCTs were included, totaling 138 short and 156 standard implants. The results of the meta-analysis showed no significant differences between the short and standard implant groups in survival rate (RR = 1.02, 95% CI 0.96–1.08, p = 0.570), MBL (MD = − 0.13, 95% CI − 0.32 to 0.07, p = 0.190) and complication rate (intra-surgical complication: RR = 1.14, 95% CI 0.46–2.83, p = 0.770; post-operative complication: RR = 1.34, 95% CI 0.71–2.55, p = 0.370). Conclusions Using short implants (≤ 8 mm) combined with OSFE might be an alternative to standard implants (≥ 10 mm) with SFE when the RBH of the posterior maxilla is insufficient. Based on a short-term clinical observation, short implants with OSFE show good results in terms of survival rate, MBL, and complication incidence. Graphical Abstract

“…The present study does not supply long-term outcomes either. However, a systematic review with a meta-analysis reported that the collagen membrane is the most used method for protecting sinus mucosa perforations [ 41 ]. The same review also concluded that such perforations do not entail a risk factor for dental implant survival.…”

Background: Perforation of the sinus mucosa is quite a frequent complication that might occur during sinus floor elevation. The perforation is often protected with a collagen membrane to avoid the extrusion of graft particles within the sinus. However, this procedure might hinder the innate osteogenic potential of the sinus mucosa. Hence, the aim of the study was to evaluate the influence of a placement of a collagen membrane subjacent the Schneiderian membrane during sinus floor elevation on implant bone healing. Methods: Twenty volunteers took part in the trial. Ten were randomly included in the group that received a collagen membrane subjacent the sinus mucosa (Mb group), and ten did not receive the membrane (non-Mb group). A collagenated corticocancellous porcine bone was used to fill the elevated space. Six 6 months after the sinus floor elevation, a mini implant was placed transcrestally and retrieved after a further 3 months. Histological analyses were then performed on the full body of the mini implant as well as on its coronal and apical portions. Results: The new bone apposition proportion onto the implant surface was similar in the Mb and non-Mb groups, both in the apical and coronal portions of the mini implants. A lesser amount of graft was found in contact with the surface. New bone density around the mini implants were similar both in the apical and coronal portions. However, a statistically higher proportion of graft particles was found in the Mb group compared to the non-membrane group. Conclusions: The placement of a collagen membrane subjacent the sinus mucosa did not affect bone healing at implants and bone density.
