چکیده

The aim of present study is to evaluate the implant stability, operative time and patient satisfaction of short dental implants (6mm) alone, short dental implants (8mm) combined with OSFE and standard dental implants (10mm) combined with OSFE for treating atrophic posterior maxilla of partially edentulous. 33 patients with 33 implants (Group 1: 9, Group 2: 12, Group 3: 12) were included in the present study. Implant survival rate, RFA measurements, operative time and patient satisfactory were evaluated. Comparison will be made among the 3 groups using ANOVA. The implant survival rates were 100% in all three groups. At implant placement, the mean ISQ values were 66.56 in group 1, 69.22 in group 2 and 70.78 in group 3. At implant impression, the mean ISQ values were 72.15 group 1, 70.67 in group 2, and 71.78in group 3. The operative time in group 1 (mean: 529.3±27.6) was significantly shorter than those in group 2 (mean 781.3±43.5) and group 3 (mean 820.8±54.1) (P<0.01). No significant difference of the intraoperative discomfort and postoperative pain scores was found among three groups. High survival rates, enough primary and secondary implant stability and excellent patient satisfactory can be achieved in all three groups. Short-6-mm implants group showed significantly shorter operative time. Future studies with large sample size should explore the difference of patient satisfactory among the three treatment strategies.

Outcome of short implants as an alternative to sinus lift surgery and standard-length implants for rehabilitation of atrophic posterior maxilla: A clinical trial

Background and Aims: The aim of this study was to assess the outcome of short implants (<8 mm length) as an alternative to sinus lift surgery and placement of standard-length implants (10-12 mm length) for rehabilitation of atrophic posterior maxilla. Materials and Methods: In this prospective clinical trial, 26 patients with 6-7 mm of residual alveolar bone height in their atrophic posterior ...

Clinical evaluation of short 6-mm implants alone, short 8-mm implants combined with osteotome sinus floor elevation and standard 10-mm implants combined with osteotome sinus floor elevation in posterior maxillae: study protocol for a randomized controlled trial

BACKGROUND Nowadays, short dental implants are being increasingly applied in extremely resorbed posterior regions. The recent studies have indicated that short implants present a similar success rate to conventional implants. It is assumed that short implants can avoid additional surgical morbidity and are less technically demanding. However, high-quality evidence (≥ Ib: evidence from at least ...

Paradigm Shift in the Management of the Atrophic Posterior Maxilla

When the posterior maxilla is atrophic, the reference standard of care would be to perform sinus augmentation with an autologous bone graft through the lateral approach and delayed implant placement. However, placement of short implants with the osteotome sinus floor elevation technique and without graft can be proposed for an efficient treatment of clinical cases with a maxillary residual bone...

Localized sinus elevation and osteocompression with single-stage tapered dental implants: technical note.

In the atrophic posterior maxilla, placement of longer (at least 10 mm) and wider diameter implants may significantly improve long-term results, but sinus grafting is often necessary to provide sufficient bone volume for implant support. The crestal approach to sinus augmentation requires penetration of the sinus floor with surgical instruments that are often difficult to control; there is a hi...
