The purpose of this investigation was to examine the regeneration of alveolar bone following surgical and non-surgical periodontal treatment. A total of 16 patients who had advanced periodontitis and demonstrated angular bony defects on radiographs participated in the study. After the initial examination, they received instruction in oral hygiene and had their teeth thoroughly scaled. When the individual patient at 2 succeeding appointments had plaque on less than 20% of the tooth surfaces, one maxillary and one mandibular quadrant was treated with the modified Widman flap procedure while one of the remaining quadrants was treated with the reverse bevel flap procedure. The last quadrant was treated with root planing under local anesthesia. None of these procedures included bone contouring. Following treatment, the patients were recalled every 2 weeks for professional tooth cleaning. Radiographs taken 12 months following treatment revealed that only minor changes in the bone level had occurred in areas with horizontal bone loss following the various treatment modalities. Following the modified Widman flap procedure, however, a statistically significant coronal regrowth of bone (0.5 mm) had occurred in angular bony defects. The majority of the angular bony defects persisted following all 3 treatment modalities.
本研究的目的是检查手术和非手术牙周治疗后牙槽骨的再生情况。共有16名患有重度牙周炎且在X线片上显示有角形骨缺损的患者参与了该研究。在初始检查后，他们接受了口腔卫生指导，并对牙齿进行了彻底的洁治。当个体患者在连续两次就诊时牙面菌斑少于20%时，一个上颌象限和一个下颌象限采用改良Widman翻瓣术治疗，而其余象限之一采用反斜面翻瓣术治疗。最后一个象限在局部麻醉下进行根面平整。这些操作均未包括骨轮廓修整。治疗后，每2周召回患者进行专业的牙齿清洁。治疗后12个月拍摄的X线片显示，在采用各种治疗方式后，水平骨吸收区域的骨水平仅发生了微小变化。然而，在改良Widman翻瓣术后，角形骨缺损处出现了具有统计学意义的骨冠向再生（0.5毫米）。在所有三种治疗方式后，大多数角形骨缺损仍然存在。
