In many cases it is necessary to perform a frenectomy to prevent reopening of a midline diastema following closure by orthodontic therapy. Often the loss of the interdental papilla between the maxillary incisors during the classic frenectomy creates an unacceptable esthetic result. A surgical technique combining a frenectomy with a laterally positioned pedicle graft is presented. The interdental papilla is left surgically undisturbed if it is of physiologic size. If it is enlarged, gingivoplasty is performed to reduce it to an appropriate size. Closure across the midline by laterally positioning gingiva and healing by primary intention results in attached gingiva across the midline. This attached gingiva may have a bracing effect and thus aid in preventing orthodontic relapse (reopening of the diastema). Twenty-seven cases were treated. No relapse was found in 24 cases and in 3 cases only minimal relapse was noted (less than 1 mm). The esthetic result is superior to that obtained with the classic frenectomy technique.
在许多情况下，有必要进行系带切除术，以防止正畸治疗关闭中线间隙后重新张开。经典的系带切除术中，上颌切牙之间的龈乳头缺失常常会导致美学效果不佳。本文介绍了一种将系带切除术与侧向带蒂移植相结合的手术技术。如果龈乳头大小正常，则手术时不扰动它。如果龈乳头增大，则进行牙龈成形术将其缩小至合适大小。通过侧向定位牙龈并一期愈合来关闭中线，可形成跨越中线的附着龈。这种附着龈可能具有支撑作用，从而有助于防止正畸复发（间隙重新张开）。共治疗了27例患者。24例未发现复发，3例仅出现轻微复发（小于1毫米）。美学效果优于经典系带切除术技术。
