摘要: 目的: 研究比较数字化先锋钻导板和全程导板在全口种植手术中的精度,以提高全口种植手术的疗效。方法: 收集2016年10月~2020年10月在天津医科大学口腔医院种植科行数字化导板辅助下全口种植的患者15例,年龄(57.5±6.3)岁,男12例,女9例。6例为上下颌全牙列缺失,9例为单颌牙列缺失,其中上颌牙列缺失11例,下颌牙列缺失10例,共21例。11例应用数字化先锋钻导板,植入56颗种植体,另外10例应用全程导板,植入65颗种植体,共计植入121颗种植体。对比术后与术前设计的种植体三维位置,评估两种数字化导板精度以及种植手术时长。结果: 121颗种植体全部在数字化导板的引导下顺利植入。其中1例上颌牙列缺失患者,1颗种植体在临时修复体戴入3个月后脱落,随后利用剩余的5颗种植体顺利完成最终修复。无论在上颌或下颌,全程导板引导下的种植体植入轴向角度、颈部和根端偏差均小于先锋钻导板(P<0.05)。应用全程导板的病例手术时长无论是在上颌或下颌,均明显短于应用先锋钻导板的病例。结论: 应用数字化导板可更好的实施全口种植手术,数字化全程导板比先锋钻导板具有更高的精准性,且耗时更短。

Abstract: Objective: To evaluate the clinical outcome of full arch implant placement using digital pioneer drilling guide and full guide. Methods: The present study was conducted on 15 patients who received full arch implant placement in the Department of Implantology School and Hospital of Stomatology, Tianjin Medical University between October 2016 to October 2020. There were 6 males and 9 females aged (57.5±6.3) years. There were 6 cases of complete dentition loss and 9 cases of single arch dentition loss. For specific surgical site, 11 were maxilla edentulous and 10 were mandible. 11 cases were conducted with the help of digital pioneer drilling guide and the other 10 cases were accomplished using digital full guide. A total of 121 implants were placed. Three dimensional positions of implants were compared pre- and post-surgery to assess the accuracy of these digital guides. The accuracy of the two digital guides and the duration of implant operation were evaluated. Results: 121 implants were placed under digital guide. One implant disloaded three months after provisional prosthesis and the patient was subsequently loaded on the rest 5 implants. All other cases were finished according to the original plan and no failure happened during the review period. For maxillary and mandible fully guided implant placement, the implant insertion axial direction angulation, and cervical and apical deviation were significantly smaller than digital pioneer drilling guided surgery (P<0.05). The operation time of patients with full digital guide was significantly shorter than that of patients with pioneer drill guide, no matter in maxilla or mandible. Conclusion: Full guided system is more accurate and reduced the operation time in contrast to pioneer drilling guided for full arch implant placement.
