下颌后牙缺失,尤其是下颌第一磨牙缺失最为常见,对患者的口颌功能造成明显损害。快速、有效地修复缺失的后牙成为医生和患者关注的主要焦点,也是口腔种植修复领域研究的热点[1]。经典的口腔种植修复为二阶段埋入式种植修复,即一期植入种植体,愈合6个月,二期手术连接愈合基台,再愈合2个月开始种植修复,是目前常用的种植方式[2]。另一种为非埋入式种植修复,即在种植体植入即刻连接愈合
Mandibular loss of the posterior teeth, especially the loss of the first mandibular first most common molars, causing significant damage to the patient’s jaw function. Rapid and effective repair of missing posterior teeth has become a major focus of attention of doctors and patients and is also a hot area of research in the field of dental implants [1]. The classic oral implants for two-stage implant implant repair, that is, a period of implants, healing for 6 months, the second stage of operation to connect the healing abutment, and then healing for 2 months to start planting and repairing, is currently used in planting methods [2]. The other is non-embedded implant repair, that is implanted in the implant immediately connected heal
