To evaluate and analyze the clinical effect of CBCT imaging technology on the restoration of upper anterior teeth of the elderly.
36 elderly patients with upper anterior teeth loss in our hospital from January 2018 to January 2020 were selected for implant restoration. Patients were equally randomized into a curved tomographic restoration group (TR group) and a CBCT restoration group (CR group). Patients in the two groups underwent traditional implant restoration. Then we compared and analyzed the implant migration, the adjustment time of first wearing, and the success rate of axial gingival recession and restoration satisfaction of patients in the two groups.
The neck offset and the root offset of the implants in the CR group was (0.77±0.15) mm and (0.83±0.17) mm, respectively, which were significantly lower than (1.25±0.27) mm and (1.73±0.29) mm in the TR group (t=6.593, t=11.359, all P<0.01). The initial wearing adjustment time of patients in the CR group [(8.73±1.94) min] was significantly less than (18.79±4.85) min in the TR group (t=8.171, P<0.01); the CR group had a significantly higher success rate of axial gingival recession as compared to the CR group (94.44% vs 61.11%, χ=6.0857, P<0.05); The restoration satisfaction rate of patients in the CR group was 100%, which was significantly higher than 77.78% of the TR group (χ=8.7429, P<0.05).
The CBCT imaging technology has a significant clinical effect on the restoration of the upper anterior teeth of the elderly, which effectively reduces the deviation of implant placement, shorten the adjustment time of their initial wearing, and greatly improves the success rate of axial gingival recession, effectively guarantees the long-term stability and aesthetics of dental implant restoration, and significantly enhances the satisfaction of patients.
评估和分析CBCT成像技术对老年患者上前牙修复的临床效果。
选取2018年1月至2020年1月在我院就诊的36例上前牙缺失的老年患者进行种植修复。将患者随机分为曲面断层扫描修复组（TR组）和CBCT修复组（CR组），每组各18例。两组患者均接受传统种植修复。然后比较分析两组患者种植体的迁移情况、初次佩戴的调整时间、轴向牙龈退缩成功率及修复满意度。
CR组种植体颈部偏移量和根部偏移量分别为（0.77±0.15）mm和（0.83±0.17）mm，显著低于TR组的（1.25±0.27）mm和（1.73±0.29）mm（t=6.593，t=11.359，P均<0.01）。CR组患者初次佩戴调整时间为（8.73±1.94）min，显著少于TR组的（18.79±4.85）min（t=8.171，P<0.01）；CR组轴向牙龈退缩成功率显著高于TR组（94.44%比61.11%，χ=6.0857，P<0.05）；CR组患者修复满意度为100%，显著高于TR组的77.78%（χ=8.7429，P<0.05）。
CBCT成像技术对老年患者上前牙修复具有显著临床效果，能有效减少种植体植入偏差，缩短初次佩戴调整时间，大幅提高轴向牙龈退缩成功率，有效保证种植牙修复的长期稳定性和美观性，显著提高患者满意度。
