数字化口腔种植技术的临床应用分析

Clinical application of digital dental implant technology

目的研究数字化口腔种植技术的临床效果与优势,为提高种植手术的精确度寻找可靠依据。方法以2015年~2016年我院口腔外科行种植手术的50例牙列缺损患者为研究对象,随机分为A、B两组,其中A组行无种植导板辅助植入种植体,B组行快速成型技术制作数字化导板,辅助植入种植体,术后对两组患者行口腔颌面部锥形束CT检查,并比较术前和术后的图形配准融合差异。结果 A组患者种植体顶部、根尖部、深度、角度偏差均显著大于B组(P<0.001),且治疗总有效率低于B组(P<0.001),桩核脱落和刺激痛则明显高于B组(P<0.05),差异有统计学意义。结论数字化导板辅助种植手术能将种植体植入口腔内,精确度高,效果良好,是一种值得临床推广的治疗方式。

Objective To study the clinical effect and advantage of digital dental implant technology and to find a reliable basis for improving the accuracy of implant surgery. Methods From 2015 to 2016, 50 patients with dental defects undergoing dental implant surgery in our hospital were randomly divided into two groups： group A and group B. In group A, no implant guide plates were used to implant the implants; In group B, rapid prototyping techniques were used to create digital guide plates and implants were implanted.After operation, two groups of patients were examined by CT of oral and maxillofacial conical beam, and the difference of image registration and fusion before and after operation was compared. Results In group A, the apical, depth and angle deviations of implants were significantly higher than those in group B（P〈0.001）, and the total efficiency of treatment was lower than that of group B（P〈0.001）.Post-core detachment and irritation pain were significantly higher than that in group B（P〈0.05）, the difference was statistically significant. Conclusion Digital guide plate assisted implant technology could complete implantation in the oral cavity with high accuracy and good effect. It is a clinically popular treatment method.
