锥形束CT联合静态导板技术在基层医院口腔种植修复中的临床应用OA

Objective:To evaluate the clinical efficacy of cone beam computed tomography(CBCT)combined with static surgical guide technology in dental implant restoration at primary-level hospitals.Methods:A retrospective analysis was conducted on 22 patients(38 implants)treated with CBCT and static surgical guide technology(guide group)and 22 patients(36 implants)treated with conventional freehand implant surgery(control group)from January 2022 to June 2024.Implant placement accuracy(coronal deviation,apical deviation,angular deviation)and postoperative complications were compared.Results:The guide group demonstrated significantly superior implant placement accuracy with coronal deviation(0.68±0.21)mm,apical deviation(0.92±0.28)mm,and angular deviation(2.14±0.73)° compared to the control group[(1.43±0.37)mm,(1.87±0.42)mm,and(4.76±1.24)°]respectively(all P<0.05).The complication rate was similar between the guide group and the control group.Conclusion:CBCT combined with static surgical guide technology significantly improves the precision and safety of dental implant restoration in primary hospitals,it has an advantage in improving the accuracy of planting and may also help reduce the risk of dissection,warranting broader clinical application.
