Background: Although small perforation of the maxillary sinus schneiderian membrane is a well-documented complication during lateral sinus floor elevation (LSFE), complete perforations larger than 10 mm often result in discontinuation of surgery. Reports on reentry LSFE and its long-term outcomes are sparse. Purpose: To evaluate the long-term outcomes of reentry LSFE following complete membrane perforation to elucidate the technical details of the reentry procedure.

Background: Bone ring (BR) grafts have been introduced to reconstruct alveolar ridge defects with simultaneous implant placement, but its clinical effectiveness remains undetermined. This systematic review aimed to comprehensively investigate BR grafts in diverse scenarios of ridge defect with simultaneous or staged implant placement. Methods: Electronic retrieval of MEDLINE, Embase, Cochrane Library(CENTRAL), Web of Science, Scopus, and citation search until August 3, 2023, was used to identify relevant clinical articles that utilized BR grafts for ridge defect reconstruction. The quality of evidence in the studies reviewed was assessed with the Joanna Briggs Institute Critical Appraisal tool. The protocol was registered in Prospective Register of Systematic Reviews (CRD42023453943). Results: Fourteen studies with 251 BRs were identified, of which 8 studies were for alveolar ridge augmentation, 4 studies were for extraction socket augmentation, and 2 studies were for sinus floor elevation. Reported sources of BRs included autografts, allografts, and xenografts. The follow-up period ranged from 4 months to 4.7 years. Regarding the primary outcomes, the utilization of BR grafts demonstrated favorable bone gain along with acceptable graft absorption and marginal bone loss. Regarding the secondary outcomes, satisfactory bone mineral density and implant stability were confirmed, accompanied by a recorded incidence of postoperative complications (20 cases) and an implant failure rate of 5.58%. Conclusions: BR grafting with simultaneous or staged implant insertion is an effective approach for reconstructing alveolar ridge deficiencies. The BR grafts demonstrate favorable bone remodeling and osteointegration with the alveolar bone and implant; however, its success may be compromised by complications. Future studies should further investigate the clinical efficacy of BR grafting comparing to other bone augmentation techniques in diverse scenarios.

Challenging Issues on Paranasal Sinuses

“…formation surrounding the graft material can impair the blood supply coming from the walls of the sinus, thus representing an impediment for the maturation of the graft and the recovery period [67]. More recently, "the intrasinusal locking technique" has been proposed by Sindel et al [68], which allows for simultaneous implant placement in the presence of a large membrane perforation aiming to decrease the number of surgical interventions and the complications related to surgery. In this technique, autogenous bone ring blocks harvested from mandibular symphysis are placed internal to the floor of the maxillary sinus and stabilized with the simultaneously installed dental implant, using a mechanism similar to that of a screw and nut ( Figure 5).…”

Dental implant rehabilitation of the posterior maxillary region has always been a challenging issue due to both alveolar ridge atrophy and sinus pneumatization. Maxillary sinus augmentation is a well-known and predictable procedure in vertical deficiencies of the posterior maxilla. To date, various techniques have been described based on the physiology of intrasinus bone repair to obtain better outcomes. Nevertheless, these procedures could also be associated with several intra-and postoperative complications such as perforation of the sinus membrane, hemorrhage, infection, graft resorption, and loss of the graft or implants. The aim of this chapter is to review the contemporary methods for maxillary sinus augmentation and to present both recommendations for prevention and management of the associated complications.
