Abstract

BACKGROUND: The present study was to evaluate the clinical and spiral computer tomographic outcome of Misch & Judy Division B Ridge defects following reconstructive surgery with the use of corticocancellous block autograft harvested from the symphysis region and were followed for 6 months interval. MATERIALS & METHOD: Nine patients selected from the Outpatient Department of Periodontics, Ragas Dental College & Hospital, Chennai, were included in this clinical trial for horizontal ridge augmentation using corticocancellous block autograft obtained from the symphysis region. These patients exhibited with Misch & Judy Division B ridge defect, with missing single tooth in the maxillary and mandibular region. All these patients were assessed clinically and with spiral Computer Tomography at baseline and 6 months. The clinical parameters assessed were mean width of keratinized gingiva, mean changes in the horizontal ridge dimension using spiral computer tomography and mean changes in the vertical bone height at the edentulous site using radiographs were done at baseline and 6 months. Statistical analysis was done using paired T test. RESULTS: At the end of 6 month period there was no significant difference in the mean width of keratinized gingiva at the augmented sites. Spiral Computer Tomographic analysis at the augmented sites exhibited an average increase of 1.6 mm at the crest level, 2.9mm at 2mm level from the crest and 2.8mm at 4mm from the crest level 6 months post operatively. In terms of radiographs at the vertical bone changes at the augmented sites most of the sites exhibited loss of crestal bone at 6 months with a change of 2.5mm. CONCLUSION: The present clinical study clearly demonstrates the use of corticocancellous autogenous block graft in horizontal ridge augmentation of Misch & Judy Division B ridge defects as a predictable treatment modality.
