This study presents the clinical results of a surgical technique that expands a narrow ridge when its orofacial width precludes the placement of dental implants. In 170 people, 329 implants were placed in sites needing ridge enlargement using the endentulous ridge expansion procedure. This technique involves a partial-thickness flap, crestal and vertical intraosseous incisions into the ridge, and buccal displacement of the buccal cortical plate, including a portion of the underiying spongiosa. Implants were placed in the expanded ridge and allowed to heal for 4 to 5 months. When indicated, the implants were exposed during a second-stage surgery to allow visualization of the implant site. Occlusal loading was applied during the following 3 to 5 months by provisional prostheses. The final phase was the placement of the permanent prostheses. The results yielded a success rate of 98.8%.
本研究展示了一种外科技术的临床结果，该技术用于在口腔面部宽度妨碍种植体植入时扩展狭窄的牙槽嵴。在170例患者中，采用无牙颌牙槽嵴扩展术在需要牙槽嵴扩大的部位植入了329颗种植体。该技术包括一个部分厚度的皮瓣、牙槽嵴顶和垂直的骨内切口，以及颊侧皮质骨板（包括部分下方松质骨）的颊向移位。将种植体植入扩展后的牙槽嵴并使其愈合4至5个月。如有需要，在二期手术中暴露种植体以观察种植体部位。在接下来的3至5个月内通过临时修复体施加咬合负荷。最后阶段是植入永久性修复体。结果成功率为98.8%。
