摘要:
目的：探讨3D椅旁计算机辅助设计和制作（Computer aided design/manufacturing,CAD/CAM）全瓷高嵌体修复后牙 大面积缺损的临床效果。方法：回顾性分析2019年9月-2022年10月笔者医院收治的86例后牙大面积缺损患者，依据治疗方 式不同分成对照组（传统印模全瓷修复）41例和观察组（CAD/CAM全瓷高嵌体修复）45例，记录两组临床指标，分析两组术 后即刻与术后6个月的修复效果，观察两组修复前与修复后6个月龈沟液量与碱性磷酸酶（Alkaline phosphatase，ALP）、 天门冬氨酸转氨酶（Aspartate transaminase，AST）水平及口腔卫生指数。结果：观察组平均备牙时间、平均调牙合时间均 短于对照组，差异具有统计学意义（P＜0.05）；修复即刻，两组修复效果比较差异无统计学意义（P＞0.05）；修复6个月 后，观察组边缘密合性、修复体完整性、修复体颜色、继发龋、修复体形态及食物嵌塞A级患者占比均高于对照组，差异具 有统计学意义（P＜0.05）；修复6个月后，观察组龈沟液量、ALP及AST水平均低于对照组，简化牙石指数、简化软垢指数得 分低于对照组，差异具有统计学意义（P＜0.05）。结论：对于后牙大面积缺损患者使用3D椅旁CAD/CAM全瓷高嵌体修复美学 效果较高，且操作时间短，对牙周组织影响小，有利于口腔卫生。
Abstract:
Objective To investigate the oral aesthetic value of 3D chairside computer-aided design/computer-aided manufacturing (CAD/CAM) all-ceramic onlays in repairing large defect of posterior tooth. Methods A total of 86 patients with large defect of posterior tooth who were admitted to the author’s hospital from September 2019 to October 2022 were reviewed. 41 patients treated with traditional impression all-ceramic restoration and 45 patients treated with CAD/CAM all-ceramic onlay restoration were defi ned as the control group and the observation group, respectively. Clinical indicators in the two groups were recorded. Repair eff ects in the two groups immediately and 6 months after operation were analyzed. Gingival crevicular fl uid volume, the levels of alkaline phosphatase (ALP) and aspartate transaminase (AST), and oral health index in the two groups before repair and at 6 months after repair were recorded. Results The average tooth preparation time and average occlusion adjustment time in the observation group were shorter than those in the control group (P＜0.05). There was no statistically signifi cant diff erence in repair eff ect between the two groups immediately after repair (P ＞0.05). Six months after repair, the proportions of grade A marginal fi t, prosthesis integrity, prosthesis color, secondary caries, prosthesis shape, and food impaction in the observation group were higher than those in the control group (P＜0.05). Six months after repair, gingival crevicular fl uid volume, ALP and AST levels in the observation group were smaller/lower than those in the control group. The calculus index simplifi ed score and debris index- simplifi ed score were lower than those in the control group (P ＜0.05). Conclusion Applying 3D chairside CAD/CAM all-ceramic onlays in repairing large defect of posterior tooth can achieve good aesthetic eff ects, and the operation time is short, with little infl uence on periodontal tissues, which is benefi cial to oral hygiene.
