【摘要】：目的：观察环状植骨术同期牙种植短期临床效果并总结其相关手术操作要点,为临床操作提供指导。方法：7例牙槽骨严重吸收的患者接受环状植骨术同期植入种植体,术后五个月行上部修复。分别于术前和术后3-5个月时拍口腔CT,测量牙槽骨增加高度和唇舌侧骨吸收量。于上部冠修复后3个月时,对其牙龈附着水平、牙龈乳头分级和牙周探诊深度进行测量分析。比较唇舌侧骨吸收量和种植牙位与邻牙牙周探诊深度的差异。统计骨环的成活率及种植体的存留率,同时观察术后并发症并了解患者的满意度。结果：术后3-5个月复查,骨环成活率为89%,种植体的存留率为100%。骨高度平均增量为6.94mm,骨吸收量平均为2.64mm,种植体颈部平均骨厚度为7.52mm,平均附着龈水平近中为1.94mm,远中为1.81mm,唇舌侧骨吸收量比较及种植体与邻牙龈沟探诊深度的比较均无统计学差异。术后无明显的并发症,修复效果好,患者满意度高。结论：环状植骨术同期植入种植体,手术操作相对容易,缩短了治疗疗程,近期效果可靠,远期效果有待进一步观察。
[Abstract]:Objective: to observe the short-term clinical effect of dental implants in annular bone grafting and summarize the relevant operative points to provide guidance for clinical operation. Methods Seven patients with severe alveolar bone resorption underwent annular bone grafting and implants were implanted at the same time. The upper part was repaired 5 months after operation. Oral CTS were taken 3-5 months before and 3-5 months after operation to measure the height of alveolar bone and the bone resorption of lip and tongue. Gingival attachment level, gingival papilla grading and periodontal probing depth were measured and analyzed 3 months after upper crown restoration. To compare the amount of bone resorption and the depth of periodontal diagnosis between the implant and adjacent teeth. The survival rate of bone ring and the survival rate of implant were counted, and the postoperative complications and patients' satisfaction were observed. Results: the survival rate of bone ring was 89 and the survival rate of implant was 100. The average increment of bone height was 6.94 mm, the average bone resorption was 2.64 mm, the average bone thickness of implant neck was 7.52 mm, the average attachment gingival level was 1.94 mm in the middle and 1.81 mm in the distal. There was no significant difference in the amount of bone resorption in the lip and tongue and the depth of probing between the implant and the adjacent gingival sulcus. There were no obvious postoperative complications, good repair effect and high patient satisfaction. Conclusion: the implantation of implants with annular bone graft is relatively easy to operate and shortens the course of treatment. The short term effect is reliable and the long-term effect needs further observation.
