Maxillary Sinus Membrane Repair With Amnion–Chorion Barriers: A Retrospective Case Series

Abstract

This retrospective case series shows nine perforations during 104 lateral window maxillary sinus augmentation procedures. A total of 23 dental implants were placed in the augmented sinuses with perforated Schneiderian membranes, and one failure was noted according the Albrektsson success criteria. A total of 158 dental implants were placed in non-perforated augmented sinuses, with a total of three failures noted.

Does intraoperative perforation of Schneiderian membrane during sinus lift surgery causes an increased the risk of implants failure?: A systematic review and meta regression analysis

“…At this stage of the analysis, 42 studies were excluded because they did not meet inclusion criteria. Finally, a total of 58 studies met the inclusion criteria and were processed for critical review …”

“…A total of 2947 patient enrolled in 58 studies (35 RCTs and 23 unrandomized studies) . A total of 7358 implants were installed in posterior atrophic maxillae following 3884 SFE, either via lateral approach ( n = 3438) or crestal ( n = 446). The follow‐up time was varied from 4 months to 5 years.…”

“… The follow‐up time was varied from 4 months to 5 years. A total of 859 lateral approach were performed using piezosurgical in nine studies or rotary burs ( n = 2541) . Crestal sinus lift were performed using osteotome according to summer technique in 14 studies .…”

“…A total of 1291 patients with 1657 sinuses involving 4814 implants enrolled in 13 studies compared to perforated sites against nonperforated sites in term of implants loss before and after functional loading . The follow‐up time ranged from 6 months to 8 years.…”

A clinical case of perforation of the maxillary sinus membrane during sinus lift surgery and a proposed methodology for the management of subsequent complications

“…For instance, utilizing titanium pins to fix the collagen membrane covering the rupture (13), using amnion-chorion membranes (14), platelet-rich fibrin (15), or a suturing technique to close large sinus mucosa perforations (16). Each of these methods has its application in clinical cases.…”
