目的评价前牙区牙槽骨水平宽度不足的患者联合应用骨劈开、骨挤压和骨引导再生术行同期种植体植入的临床效果。方法 2004—2009年福州市第一医院口腔科就诊的前牙区牙缺失伴前牙区牙槽骨水平宽度不足的种植患者28例,联合应用骨劈开、骨挤压,填入骨粉,行骨引导再生术后同期植入40颗种植体,术后4～6个月内完成上部修复。术后1年,通过临床检查、全景片等观察效果。结果术前、后牙槽骨平均宽度分别为(3.2±0.89)mm、(6.5±0.75)mm,平均增加了(3.3±0.34)mm。术后牙槽骨宽度与术前相比,差异有统计意义(t=2.47,P<0.05)。术后无明显并发症发生,种植体行使功能良好,仅1例患者的1颗牙种植失败,种植近期成功率达97.5%。结论对前牙区牙槽骨水平宽度不足的患者,联合应用骨劈开、骨挤压和骨引导再生术行同期种植体植入,可增加骨量,获得种植体的同期植入,减少患者痛苦,改善种植修复的临床效果。
OBJECTIVE: To evaluate the clinical effect of simultaneous implantation of bone splitting, bone compression and bone guided regeneration in patients with an insufficient level of alveolar bone in anterior teeth. Methods From 2004 to 2009, Fuzhou First Hospital Stomatology treatment of anterior teeth missing with anterior teeth alveolar bone width less than 28 cases of planting patients, the combined application of bone splitting, bone extrusion, filling the bone meal, line After the bone-guided regeneration, 40 implants were implanted in the same period and the upper repair was completed within 4 to 6 months after the operation. After 1 year, through clinical examination, panoramic film and other effects observed. Results The average width of anterior and posterior alveolar bone were (3.2 ± 0.89) mm and (6.5 ± 0.75) mm respectively, with an average increase of (3.3 ± 0.34) mm. The width of the alveolar bone after operation was significantly higher than that before operation (t = 2.47, P <0.05). No postoperative complications occurred and the implants performed well. Only one patient had failed dental implants and the immediate success rate was 97.5%. Conclusions For patients with insufficient level of alveolar bone in the anterior teeth, simultaneous application of osteotomy, osteosynthesis and bone-guided regeneration during the same period of implantation can increase the bone mass, achieve simultaneous implantation of implants and reduce the patients’ Pain, improve the clinical effect of implant repair.
