This study was done in order to monitor human osseous remodeling following periodontal surgery including osseous recontouring.
26 sites in 17 patients presenting pockets ranging from 4 to 7 mm received an apically positioned flap including osteoplasty and ostectomy. A stent was used for the clinical measurements during surgery. The measurement taken was the distance between the base of the stent to the crest of the alveolar bone at the mesio-facial, mid-facial, and distofacial site. This measurement was taken before and after bone recontouring and after 3 and 6 months.
Results showed that the amount of bone resected for both groups was similar. There was an interradicular bone reduction of 0.38 mm at 3 mo. and 0.23 mm at 6 mo. At the radicular site, the loss was 0.84 mm at 3 mo. and 0.55 mm at 6 mo. In the furcation site the loss was 0.79 mm at 3 mo. and 0.88 mm at 6 mo. All these differences were significant as compared to measurements taken right after bone recontouring.
The bone was recontoured in favor of scalloping and grooved areas presented buttressing bone formation.
