Abstract
AIM: The purpose of this study was to evaluate a new surgical concept with new tools utilized for crestal sinus elevation to determine the incidence of sinus membrane perforation during surgery. A completely new approach, associated with new instruments, allows sinus bone grafting in all cases of atrophy of the posterior maxilla.
BACKGROUND: Crestal sinus augmentation is frequently required for implant placement in the maxillary molar sites to provide sufficient crestal height to permit implant placement. This is performed in conjunction with implant placement at the same surgical appointment but has the potential for sinus membrane perforation and may be technique sensitive for some practitioners. The technique and instrumentation discussed in the article simplify the procedure and greatly diminish the potential of sinus perforation during treatment. Clinical technique: Two Kits are discussed, with Kit A utilized to treat maxillary atrophy presenting less than 4 mm of sub-sinus bone height, and Kit B to treat maxillary atrophy presenting more than 4 mm of sub-sinus bone height. The technique involves minimally invasive, simple surgery, using a very precise protocol and instrumentation to permit sinus elevation via a crestal approach, to eliminate sinus membrane perforation potential.
DISCUSSION: The results of this article focused on 100 cases for Kit A and 300 for Kit B, obtaining 97% success in avoiding sinus membrane perforation.
CONCLUSION: Transcrestal sinus elevation provides a very good alternative utilizing the All Secure Sinus Elevation Kit (ASSEK) A compared to older techniques that have proven themselves to have associated complications, including sinus membrane perforation. The ASSEK B allows you to perform a Summer's sinus elevation approach in direct vision for added safety Clinical significance: The design of the Kit's components avoids any complications of sinus membrane perforation. The Kit uses a minimally non-invasive surgery, avoiding any healing complications that present with more extensive surgical approaches. Sinus augmentation is frequently required for implant placement in the maxillary molar sites, especially when ridge resorption has occurred. The technique and instrumentation discussed provide a simpler surgical procedure to achieve increased crestal height with significantly decreased sinus perforation potential.
