Early review of the OMSFE/PRF technique presented for localized sinus floor elevation and implant placement demonstrates a high degree of safety and success at sites with 5- to 8-mm residual subantral bone height.

This retrospective case series from clinical private practices confirmed that a lateral window approach to sinus elevation incorporating piezoelectric technology in conjunction with hand instrumentation was an effective means to achieve sinus elevation while minimizing the potential for intraoperative complications. Further prospective and randomized controlled studies are warranted to qualify these observations.

Introduction: Combination guided tissue regeneration (GTR) for the treatment of periodontal intrabony defects has been an accepted treatment modality for nearly 30 years and has undergone a number of changes during this time, including the use of multiple different barrier membrane materials. Amnion–chorion membrane (ACM) is a placental‐derived tissue that has been used in medicine for >100 years and recently introduced for combination GTR use in dentistry. This retrospective observational report documents use of ACM for combination GTR treatment of periodontal intrabony defects with a minimum of 12‐month post‐surgical observation. Case Series: Review of the practice's electronic database revealed that 114 patients were treated with GTR therapy from March 2010 to October 2011. Of these patients, 64 were treated with ACM combination GTR therapy and had ≥12 months of follow‐up. All patients were diagnosed with localized moderate‐to‐severe chronic periodontitis and exhibited radiographic evidence of ≥1 vertical osseous defect. All patients were treated by thorough degranulation of intrabony periodontal defects and placement of bone allograft covered by ACM. Clinical measurements 12 months after surgery revealed an average probing depth reduction of 5.06 ± 1.37 mm and clinical attachment level improvement of 4.61 ± 1.29 mm. Conclusion: The results of this retrospective observational report are promising and warrant additional controlled, long‐term studies to further evaluate the effectiveness of ACM for combination GTR treatment of periodontal intrabony defects.

This retrospective observational report demonstrates that the piezoelectric hinge-assisted ridge split procedure can achieve substantial gains in horizontal ridge width of the edentulous posterior mandible without associated morbidity. Further prospective and larger observational studies are warranted to see if this is true over a larger patient population and to compare this technique to other more traditionally used approaches.
