Aesthetic Effect of 3D-Printed Dental Implant Guide Under CBCT Guidance in the Restoration of Anterior Tooth Defect and Its Influence on Patients' Pe-riodontal Health Status
目的 探讨锥形束CT(CBCT)引导下3D打印种植牙导板修复前牙缺损的美学效果及对患者牙周健康状态的影响.方法 选取岳阳市口腔医院2023年1月至2025年9月收治的65例前牙缺损患者为研究对象,按照治疗方式分为对照组(32例,CBCT辅助规划下常规自由手种植修复)与研究组(33例,CBCT引导下3D打印种植牙导板修复).比较两组的种植精准度、牙齿修复效果、牙周健康状态、美学效果.结果 研究组的颈部距离、根尖部距离、深度及角度偏差均低于对照组(P＜0.05).术后6个月,两组的改良版美国公共卫生署(USPHS)各维度评分均较术前明显降低,且研究组USPHS各维度评分明显低于对照组(P＜0.05).术后1周,两组的菌斑指数(PLI)、牙龈指数(GI)及龈沟出血指数(SBI)评分均较术前明显降低,且研究组的PLI、GI、SBI评分均明显低于对照组(P＜0.05).术后6个月,两组的粉色美学评分(PES)及白色美学评分(WES)均较术后1周明显升高,且研究组的PES、WES均明显高于对照组(P＜0.05).结论 CBCT引导下3D打印种植牙导板修复前牙缺损可提升种植精准度与修复质量,改善患者的牙周健康状态,获得更佳美学效果.
Objective To explore the aesthetic effect of 3D-printed dental implant guide under cone beam computed tomography(CBCT)guidance in the restoration of anterior tooth defect,and its influence on patients' periodontal health status.Methods A total of 65 patients with anterior tooth defects treated at Yueyang Stomatological Hospital from January 2023 to September 2025 were selected as study subjects.According to treatment regimens,they were divided into the control group(32 cases,conventional free-hand implant restoration under CBCT-assisted planning)and the study group(33 cases,restoration with 3D-printed dental implant guide under CBCT guidance).The implant accuracy,tooth restoration effect,periodontal health status and aesthetic effect were compared between the two groups.Results The deviations of cervical distance,apical distance,depth and angle in the study group were all significantly lower than those in the control group(P＜0.05).At 6 months after operation,the scores of each dimension of modified United States Public Health Service(USPHS)in both groups significantly decreased compared with baseline,and the scores of each dimension of USPHS in the study group were significantly lower than those in the control group(P＜0.05).At 1 week after operation,the scores of plaque index(PLI),gingival index(GI)and sulcus bleeding index(SBI)in both groups significantly decreased compared with pre-operation,while the scores of PLI,GI and SBI in the study group were significantly lower than those in the control group(P＜0.05).At 6 months after operation,the pink esthetic score(PES)and white esthetic score(WES)of both groups were significantly higher than those at 1 week after operation,while the PES and WES in the study group were significantly higher than those in the control group(P＜0.05).Conclusions 3D-printed dental implant guide under CBCT guidance applied in anterior tooth defect restoration can improve implant accuracy and restoration quality,ameliorate patients' periodontal health status,and achieve better aesthetic effect.
