【摘要】：目的通过建立两组临床种植修复模型,采用影像学方法比较平台转移设计的骨水平种植体与软组织水平种植对种植体颈部骨量保存的影响。方法选择2009年1月-2012年12月60例在滨州市人民医院口腔科门诊就诊的单颗后牙缺失的患者,随机分为A、B两组,均采用种植修复。对照组A组应用的是韩国DIO公司生产的软组织水平种植体(IFI),实验组B组植入的是韩国DIO公司生产的平台转移设计的骨水平种植体(SM)。修复后观察12个月并于12个月时拍摄根尖片,与修复后即刻拍摄的根尖片相比较,观察种植体颈部骨量吸收的情况。结果两组患者种植体均无松动,种植体周围软组织无红肿、溢脓等感染的现象发生,种植体与骨组织形成良好的骨结合,成功率100%,患者对种植效果满意。种植体颈部骨组织保存的评价:修复前A、B两组种植体颈部周围骨吸收比较差异无统计学意义(P0.05),修复后1年种植体颈部骨吸收存在明显差异(P0.05)。结论在本实验观察范围内,平台转移设计的骨水平种植体在对后牙修复后种植体颈部骨量保存方面优于软组织水平种植体,其远期效果有待进一步观察。
[Abstract]:Objective to establish two groups of clinical implant restoration models and to compare the effects of horizontal bone implants and soft tissue implants designed by platform transfer on bone mass preservation in the neck of implants.Methods from January 2009 to December 2012, 60 patients with missing posterior teeth from outpatient department of Stomatology Department of Binzhou people's Hospital were randomly divided into two groups: group A and group B, all of which were treated with implant prosthesis.The control group A was treated with the soft tissue level implant made by DIO Company of Korea, and the experimental group B was implanted with the bone level implant designed by the DIO Company of Korea.The apical films were taken at 12 months after restoration and compared with those taken immediately after restoration to observe the absorption of bone mass in the implant neck.Results there was no loosening of implants, no swelling of soft tissue around implants, infection of abscess and so on. The implant and bone tissue formed a good bone union, and the success rate was 100%. The patients were satisfied with the effect of implantation.Evaluation of bone tissue preservation in implant neck: there was no significant difference in bone resorption between the two groups before and after repair (P 0.05), but there was a significant difference in bone resorption in implant neck one year after repair.Conclusion in the range of this experiment, the bone level implant designed by platform transfer is superior to the soft tissue horizontal implant in the preservation of the neck bone mass of the implant after posterior tooth restoration, and the long-term effect needs to be further observed.
