Donnenfeld, WO, Hoag, PM, and Weissman, DP. A clinical study on the effects of osteoplasty. J Periodontol, 41:131, 1970.

Aims

This study was done in order to investigate the effects of contouring the alveolar bone profile in the absence of intraosseous defects with respect to pocket elimination, location of the epithelial attachment and alveolar bone height.

Materials and Methods

• 4 patients were selected for a split-mouth design study. One side received a full thickness flap surgery where the granulation tissue was removed and the roots planed. The experimental side received the same procedure but osteoplasty was performed. No attempt was made to treat intraosseous defects. All areas were reflapped 6 months later.
• Measurements taken included location of the epithelial attachment and height of the interradicular bone as well as pocket depth.

Results

• Three out of the four patients received reentry surgeries. Pocket elimination was similar for both groups.
• The epithelial attachment was located 0.6 mm apical for the control and 1 mm apical for the experimental group.
• There was a loss of interproximal bone height for both procedures: 0.4 mm (E) X 0.6 mm (C).
• Radicular bone (straight buccal and lingual) was of 0.8 mm for control and 1.0 mm for the experimental group.

The results were not statistically significant when comparing control and experimental sites. Other changes that were not measured occurred in the area and could be observed by photographs. Remodeling toward ideal architecture occurred on both control and experimental sites.
