“…They concluded that the sinus membrane perforation was not shown to be a significant factor in the rate of implant complications. Numerous case reports of accidental sinus perforation during implant placement conclude that the perforation did not lead to any serious sequela or morbidity [8] [9].…”

Purpose: To assess surgical success rate of placing dental implants in the atrophic posterior maxilla engaging the maxillary sinus floor in patients with inadequate posterior maxillary alveolar bone height (PMABH). Methods: 26 patients with PMABH of 7 -10 mm had 39 implants placed between July 2012 and June 2014. These implants were placed protruding apically 1 -3 mm into the maxillary sinus engaging the sinus floor. At stage one, implants and cover screws were placed, followed by stage two, 5 -6 months later. The implants were considered osseo-integrated in the absence of symptoms, mobility and inflammation. Periapical radiographs were taken to rule out peri-implant radiolucency. Restorative treatment was completed 2 months thereafter. Patients were scheduled to have a dental exam (6 -12 months after delivery of prosthesis) and the implants were evaluated clinically and radiographically. A retrospective review was conducted to assess the surgical success rate of this treatment modality. Clinic charts, radiographs and digital implant log were reviewed for all patients with PMABH of 7 -10 mm who received dental implants in the posterior maxilla to determine the success rate of this treatment modality. Results: 26 patients who had 39 implants placed were included in the study. All implants (100%) were osseo-integrated at the time of uncovering (stage 2). None of the implants (0%) had mobility or inflammation around them. Stage 2 was successfully performed on all 39 implants (100%). All implants (100%) in these patients had been restored, and were in good condition 114without mobility or inflammation, and had been functioning well 6 -12 months after restoration. Conclusion: This study suggests that a high success rate can be attained placing dental implants in the posterior maxilla while perforating and engaging the cortical maxillary sinus floor. A future prospective study that compares this technique with the internal sinus lift would likely help elucidate this suggestion.

“…However, with large sinus membrane perforations, some authors recommend aborting the sinus augmentation procedure due to the higher percentage of implant failures associated with such large perforations [6,7,9,16,29,[38][39][40]. An alternative strategy is to repair the large sinus membrane tear or perforation using a bioresorbable collagen membrane and platelet rich plasma, but without adding the bone graft material.…”

“…Die Perforation der Schneider-Membran ist mit 12-44 % die häufigste intraoperative Komplikation. Bei adäquater Versorgung scheinen Perforationen die Implantatüberlebensrate jedoch nicht negativ zu beeinflussen (Becker et al 2008 sind Mund-Antrum-Verbindungen (10 %), Hämatome (7,4 %), Sinusitis (7,3 %), Wundinfektion (5,0 %), Verlust des Augmentats (3,1 %), Verschluss des Ostium naturale (2,5 %) und Zystenbildung in der Kieferhöhle (1,2 %;Schwartz-Arad et al 2005).…”

Zusammenfassung: Die dentale Rehabilitation teilbezahnter oder unbezahnter Kiefer durch implantatprothetischen Zahnersatz hat sich nahezu weltweit als Routineverfahren mit hoher Nachhaltigkeit etabliert. Dabei geht es nicht nur um eine funktionelle Versorgung mit ansprechender Ästhe-tik, sondern auch um den langfristigen Erhalt kaufunktionell wichtiger Strukturen (Alveolarkamm, Restbezahnung). Jedoch wird die Indikation zur Implantation häufig durch ein insuffizientes Knochenangebot infolge physiologischer Alveolarkammatrophie, Parodontopathien oder Traumata eingeschränkt. Daher entsteht in vielen Fällen die Indikation zur Augmentation vor oder simultan mit der Implantation, um dentale Implantate in prothetisch optimaler Position inserieren zu können und somit ein langfristiges funktionell-ästhe-tisches Ergebnis zu erzielen. Im folgenden Beitrag werden derzeitig gängige chirurgische Methoden der Alveolarkammaugmentation sowie deren Komplikationsbehandlung praxisrelevant dargestellt.

Prospective observation of 41 perforations of the Schneiderian membrane during sinus floor elevation

Abstract: With appropriate treatment, intraoperative sinus membrane perforations did not represent an elevated risk for implant loss, infectious complications or displacement of graft material in the investigated population.
