A technique for augmentation of the severely atrophic edentulous maxilla is presented. This technique combines the mobilization of the available soft tissue of the labial vestibule with a subperiosteal reflection and "filleting" of the redundant crestal soft tissue to create ample space to accommodate the insertion of the desired amount of hydroxylapatite. The surgical development of a distinct labial periosteal flap by both a subperiosteal and supraperiosteal dissection allows a two-layered lapped closure of the mucosal and periosteal flaps. Fourteen patients were treated with this technique and have been observed for period of 8 to 40 months. Arch form was dramatically improved in all cases. Observation of panoramic radiographs disclosed an average initial increase in ridge height of 11.8 mm in the midline and 7.6 mm in the first premolar regions. During the first 6 months, consolidation of the ridge occurred, but the diminution in ridge height never exceeded 15%.
本文介绍了一种用于严重萎缩无牙上颌骨增量的技术。该技术将唇侧前庭可用软组织的松动与骨膜下翻瓣及多余嵴顶软组织的“切除”相结合，以创造足够的空间来容纳所需量的羟基磷灰石植入。通过骨膜下和骨膜上剥离形成独特的唇侧骨膜瓣，可实现黏膜瓣和骨膜瓣的两层重叠缝合。14例患者接受了该技术治疗，并进行了8至40个月的观察。所有病例的牙弓形态均得到显著改善。全景X线片观察显示，中线处牙槽嵴高度平均初始增加11.8mm，第一前磨牙区增加7.6mm。在最初的6个月内，牙槽嵴发生巩固，但牙槽嵴高度的减小从未超过15%。
