COMPUTER-BASED QUANTIFICATION OF AN ATRAUMATIC SINUS AUGMENTATION TECHNIQUE USING CBCT

Our group recently developed an innovative maxillary sinus augmentation technique without the need of sinus membrane elevation, termed as “IPG” DET protocol. This technique utilizes autologous platelet concentrates(including platelet rich plasma (PRP), platelet rich fibrin (PRF), growth factors (GFs) and CD34+ stem cells), togrther with bone grafting aterialspositionedthrough intentionally perforated Schneider's membrane for flapless implant placement. A total of eighty-five implants were placed with “IPG” DET protocol in combination with autologous platelet concentrates. CBCT (cone beam computed tomography) was performed at two different time points: pre-operatively and at 8 months post-op. CBCT images were then compared by an intensity-based image algorithm to assess the newly formed bone in terms of gray scale values. Additionally, implant stability quotient (ISQ) was used to estimate implant osseointegration and success rate. The average new bone formation was 5.9±0.9 mmq per implant. According to the result of this study, “IPG” DET protocol in combination with autologous platelet concentrates is a successful technique forimplant-supported rehabilitation of the edentulus posterior maxilla without the need of sinus floor elevation.
