ALTHOUGH extensive buccal and lingual denudation of the alveolar process has been abandoned, bone is often exposed at the alveolar crest and in interproximal areas during periodontal surgery.The purpose of the present investigation was to study the healing after surgical denudation of small areas of the alveolar process in humans. MATERIALTen immediate denture patients at The University of Michigan, School of Dentistry, participated in the study.The patients were in good health and varied from 26 to 57 years of age.Dental records, roentgenograms and clinical pictures of the patients were available.The periodontal health status varied from clinically normal gingiva to moderately advanced periodontitis.A block section of the experimental tooth with adjacent buccal soft tissues and alveolar process, at least to the middle of the root, was obtained from each patient at the time of insertion of the immediate denture. METHODA standard record was kept providing detailed information about periodontal status and functional relations of the experimental teeth.A transverse horizontal notch extending into dentin was made on the labial surface of the experimental tooth, to serve as reference for clinical measurements before, during and after the surgery. 1 The notch was made with a small diamond wheel, about 2 mm incisally to the free gingival margin.Measurements from the gingival margin of the notch to the free gingival margin, and to the bottom of the gingival sulcus or pocket were obtained with a blunted no. 2 silver point of the type used for root canal therapy.A cotton plier was used to grasp the point at the spot where the beaks of the plier fit into the reference notch.The measurements were made with a Boley gauge.A labial and interproximal gingivectomy was then performed on the experimental tooth and the immediate
