摘  要:目的探讨不同种植设计软件对种植体位置偏差的影响。方法选取16位患者的颌骨CBCT数据,导入不同种植设计软件中进行方案设计,分别设计53颗种植体,在软件中依据种植体位置生成导板,采用光固化成型技术加工导板。将通过Sim Plant软件设计制造的导板分为A组,通过6D Implant软件设计制造的导板分为B组。导板佩戴在石膏模型上进行CBCT扫描,将获取的数据进行三维重建并配准到种植方案,依据实际的导板位置模拟确定实际的种植体位置,分析种植体实际位置与设计位置的偏差。实验获取的数据采用SPSS 11.0统计学软件进行统计分析,并进行单侧t检验。结果 A组所引起的种植体实际与设计位置颈部中心偏差为(0.582±0.216)mm,水平向偏差为(0.226±0.132)mm,垂直向偏差为(0.522±0.213)mm;种植体顶端中心偏差为(0.643±0.256)mm,水平向偏差为(0.332±0.222)mm,垂直向偏差为(0.524±0.214)mm;体积重合度为(88.7±4.6)%。B组种植体颈部中心偏差为(0.456±0.222)mm,水平向偏差为(0.193±0.123)mm,垂直向偏差为(0.388±0.238)mm;种植体顶端中心偏差为(0.515±0.233)mm,水平向偏差为(0.277±0.190)mm,垂直向偏差为(0.390±0.236)mm;体积重合度为(91.1±4.0)%。结论不同种植设计软件对种植体位置偏差的影响差异具有统计学意义。Objective To evaluate the influence of different dental implant simulation software on the accuracy of surgical template. Methods Sixteen healthy people were chosen for the analysis. All the patients were scanned with cone beam computerized tomography( CBCT) and the data were imported into the different dental implant simulation software,53 implants were planned and the stereolithographic( SLA) surgical templates were made with the technology of SLA. The surgical templates designed by Simplant were group A,designed by 6D implant were group B. A CBCT scan of the surgical template fitted on plaster model was performed,and the images were matched with the virtual implant plan images,the actual implant position was acquired from the position of surgical template. The deviation between the actual and planned implant position was analyzed. Results Group A: the deviation at the hex was( 0. 582 ± 0. 216) mm,horizontal deviation was( 0. 226 ± 0. 132) mm,vertical deviation was( 0. 522 ± 0. 213) mm; apex deviation was( 0. 643 ± 0. 256) mm,horizontal deviation was( 0. 332 ± 0. 222) mm,vertical deviation was( 0. 524 ± 0. 214) mm; contact radio was( 88. 7 ± 4. 6) %.Group B: the deviation at the hex was( 0. 456 ± 0. 222) mm,horizontal deviation was( 0. 193 ± 0. 123) mm,vertical deviation was( 0. 388 ± 0. 238) mm; apex deviation was( 0. 515 ± 0. 233) mm,horizontal deviation was( 0. 277 ± 0. 19) mm,vertical deviation was( 0. 39 ± 0. 236) mm; contact radio was( 91. 1 ± 4. 0) %. Conclusion The influence of different implant simulation software on the accuracy has statistical significance.
