Abstract

BACKGROUND: Sinus augmentation technique has been reported to be associated with a predictable implant survival in posterior atrophic maxilla. However there is insufficient literature in regards to implant survival without the use of bone replacement graft. The purpose of the present study is to evaluate the clinical & radiological outcomes and post-operative morbidity of indirect sinus floor elevation procedures with simultaneous implant placement without the use of Bone replacement graft. MATERIALS & METHODS: Ten systemically healthy patients (5 males and 3 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 RVG and residual bone height was measured. Sinus lift procedure under local anesthesia was done by a transcrestal approach using osteotomes and simultaneous implant placement was done without bone graft. Survival of implant and postoperative morbidity were recorded. The parameters assessed were length of implant protruded into sinus and Crestal bone height were observed at base line, 3rd month and 6th month using OPG and RVG and the results were analyzed. Statistical analysis was done using “One way Anova , Post Hoc test and Paired t test”. RESULTS: Clinically, no complications were observed during or after the surgical procedure. There was no significant change in the length of implant protruded into the sinus over a period of 6 months, demonstrated that there was no change in sinus floor level (P>0.05).Mesial crestal bone height in group I which is the measurement from implant collar to first crestal contact, showed 2.10±1.10mm at baseline,3.38±0.74mm at 3 months and 4.00±0.63mm at 6 months which was statistically significant (P<0.001).Two early implant failures were reported and Seven implants out of ten were successfully restored in function. CONCLUSION: Within the limits of this study, it can be concluded that indirect sinus lift with simultaneous implant placement without bone graft can be successfully used for augmentation of maxillary sinus in posterior atrophic maxilla . However, further controlled clinical trials are needed to evaluate the effectiveness and safety of this technique compared to other sinus floor elevation procedures.
