目的:评价双皮质骨种植应用于下颌后牙区萎缩牙槽骨的临床效果。方法:15例下颌磨牙区牙槽骨中重度萎缩病例,倾斜双皮质骨植入22枚种植体,随访2年,行X线片、问卷调查等随访。结果:第1年骨丧失为(0.635±0.139)mm,第2年骨丧失为(0.141±0.032)mm;15名患者均没有疼痛不适、口唇麻木或感觉减退,满意率达93%。结论:双皮质骨种植应用于下颌后牙区萎缩牙槽骨取得了满意的治疗效果。
Objective: To evaluate the clinical effect of double cortical bone implantation in the alveolar bone in the mandibular posterior teeth. Methods: Fifteen cases of moderate to severe alveolar bone atrophy in mandibular molar area and 22 implanted double cortical bone implants were followed up for 2 years. X-ray films and questionnaires were followed up. Results: The bone loss in the first year was (0.635 ± 0.139) mm and in the second year was (0.141 ± 0.032) mm. No pain or discomfort was found in all 15 patients, numbness or sensation of the lips was diminished, and the satisfaction rate was 93%. Conclusion: The double cortical bone implantation in mandibular posterior teeth area atrophy of alveolar bone and achieved satisfactory results.
