Abstract

BACKGROUND:

There are different techniques for the sinus augmentation; the factors that contribute to the survival rate of sinus augmentation and dental implant placement are still the subject of discussion. So we compare the two different ways of sinus floor elevation: a) Lateral antrostomy as a one or two step procedure as direct method. b) Osteotome technique with a crestal approach as indirect method.

MATERIALS AND METHODS:

A total of twenty partially edentulous patients in maxillary posterior region who opted for implant retained prosthesis but had a low sinus and deficient alveolar ridge within the age group of 20-55 years were taken up, 25 implants were placed in combination with bone grafting material for sinus augmentation. The final bone height was measured from Orthopantomogram. Post-operative Clinical Evaluation was based on pain, gingival inflammation status, stability, swelling and bone height. Statistical analysis was done by using Statistical Package for Social Sciences (version 15.0) (SPSS Inc., Chicago, IL, USA).

RESULTS:

The gain in bone height was significantly greater in direct procedure through lateral antrostomy (mean 8.5 mm) than in indirect method through crestal approach by osteotome technique (mean 4.4 mm).

CONCLUSIONS:

Osteotome technique can be recommended when more than 6 mm of residual bone height is present and an increase of 3-4 mm is expected. In case of more advanced resorption direct method through lateral antrostomy has to be performed. Both sinus elevation techniques did not seem to affect the implant success rate.
