A retrospective analysis of the results obtained from regenerative surgery performed utilizing a minimally invasive surgical approach was performed. Bone grafting procedures were performed at 194 sites in 87 patients using small incisions and minimal flap reflection. There were 44 females with a mean age of 52.7 years and 43 males with a mean age of 54.9 years. The mean healing time at which data were collected was 21.7 months. Postsurgical data were collected at the time of routinely scheduled supportive periodontal therapy (SPT) appointments by 2 evaluators. Mean changes in probing depth and attachment levels were evaluated utilizing a Wilcoxon sign rank test. Mean improvement in probing depth was 4.58 mm (P <0.0001) and attachment level was 4.87 mm (P <0.0001). These improvements were seen for all levels of initial prognosis (good to poor) and appeared to be stable over time. The postsurgical gingival margin was at or within 1 mm of the cemento-enamel junction (CEJ) for 58% of the sites treated. This was interpreted to indicate good retention of soft tissue height postsurgically. It was concluded that the minimally invasive approach for bone grafting yielded results that were equivalent to more traditional surgical approaches utilizing longer incisions and greater reflection.
对采用微创外科手术方法进行的再生手术结果进行了回顾性分析。在87例患者的194个部位进行了骨移植手术，采用小切口和最小程度的皮瓣翻起。有44名女性，平均年龄52.7岁，43名男性，平均年龄54.9岁。收集数据时的平均愈合时间为21.7个月。在常规安排的支持性牙周治疗（SPT）预约时，由2名评估人员收集术后数据。使用Wilcoxon符号秩检验评估探诊深度和附着水平的平均变化。探诊深度的平均改善为4.58mm（P<0.0001），附着水平为4.87mm（P<0.0001）。在所有初始预后水平（从良好到不良）均可见到这些改善，并且随着时间推移似乎保持稳定。58%接受治疗部位的术后牙龈边缘位于牙骨质-釉质界（CEJ）处或在其1mm范围内。这被解释为表明术后软组织高度保持良好。得出的结论是，骨移植的微创方法产生的结果与采用更长切口和更大翻起的更传统手术方法相当。
