title: An alternative maxillary sinus lift technique - sinu lift system.
abstract: OBJECTIVE
  Maxillary sinus augmentation surgical techniques have evolved greatly allowing successful placement of dental implants in the atrophic posterior maxillary region. The purpose of the present study is to evaluate the clinical and radiological outcomes and postoperative morbidity of sinus floor elevation procedures performed using the minimally invasive surgical technique the Sinu lift system.
  
  
  METHODS
  Sinus lift procedure was done using the sinu lift system by a transcrestal approach and bone augmentation was done on ten systemically healthy patients using β- tricalcium phosphate and platelet rich plasma mix. The study was evaluated upto six months period with bone related parameters being assessed at base line using CT scan, OPG and after six months the results were analysed using SPSS Version 18.0 software (p < 0.01 (0.005). Wilcoxson signed rank sum test was used to correlate between preoperative and postoperative measurements. Implant placements were done at the desired area of sinus augmentation with a two year follow up. (Nobel Biocare, Nobel Biocare Holding AG, Zürich-Flughafen, Switzerland) Results: The augmented sites had a significant increase in the bone parameters at the desired grafted region. The mean gain in bone height as observed in CT Scan had revealed increased measurements from 5.80mm±0.98 to 10.20mm±1.68 at the sixth month evaluation. This was statistically significant (0.005). Clinically, no complications were observed during or after the surgical procedure.
  
  
  CONCLUSIONS
  Within the limitations of this study, the Sinu lift system with a controlled working action resulted in high procedural success and this procedure may be an alternative to the currently used surgical methods.
