Abstract
BACKGROUND: The posterior maxillary segment frequently has insufficient bone mass to support dental implants. Sinus floor grafting has been proposed as a viable treatment option in such situations. The purpose of the present study is to present data on the clinical & radiological outcomes and post-operative morbidity of sinus floor elevation procedures performed using the “Sinu-lift™ system” utilizing Cersorb®M and PRP prior to implant placement. MATERIALS & METHODS: Ten systemically healthy patients (6 males and 4 females) within the age group of 25-55 years requiring maxillary sinus augmentation for implant placement were selected for the study. Pre-operative diagnostic evaluation was done using OPG and Computerized tomography scans and bone parameters were measured (Bone Height, Bone Volume & Bone Density). Sinus lift procedure under local anaesthesia was done using the “sinu-liftTM system” by a transcrestal approach and bone augmentation was done using Cerasorb®M and PRP mix. The study was evaluated upto a 6 months period with bone related parameters being assessed at base line,1st month,2nd month, 3rd month and 6th month using OPG, while CT scans were taken at base line and 6th month and the results were analyzed. Statistical analysis was done using “Wilcoxson Signed Rank Sum test”. RESULTS: Clinically, no complications were observed during or after the surgical procedure. All patients healed uneventfully, and no signs and symptoms of maxillary sinus related complications were observed during the six months period following surgery. There was a significant increase in the bone parameters at the “desired grafted region”. The mean gain in bone height as observed in OPG was 11.50mm±1.68 from 7.05mm±1.09. Similarly, CT Scan had revealed increased measurements from 5.80mm±0.98 to 10.20mm ±1.68 at the 6th month evaluation. This was statistically significant. The mean bone volume attained in G.B region was higher 98.90mm3±54.08 than the N.B region 60.32 mm3±14.39. The mean bone density of G.B region recorded an higher density of 537.59HU±148.97 when compared to the N.B region 378.02HU±90.27 after six months in CT Scan evaluation. CONCLUSION: Within the limits of this study, it can be concluded that β-Tricalcium phosphate in combination with PRP can be successfully used for augmentation of maxillary sinus in atrophic maxilla prior to implant placement. The “Sinu-lift ™ system” with a controlled working action resulted in high procedural success and because it is minimally invasive, this procedure may be an alternative to the currently used surgical methods. However, further controlled clinical trials are needed to evaluate the effectiveness and safety of this technique compared to other sinus floor elevation procedures.
