摘要

目的:设计修复体仍然具有挑战性,因为过程耗时,需要操作人员的技能和经验。本临床研究评估了基于web的3D生成人工智能设计(GAID)方法与传统计算机辅助设计(CCAD)方法制备的聚合全冠的拟合精度。材料和方法:纳入62例上颌、下颌前磨牙和磨牙需要全冠的患者。牙齿准备后,使用口内扫描仪进行数字印模。每位患者设计了两个冠:一个使用基于网络的自动3D GAID软件程序,另一个使用标准的人为驱动的CCAD软件程序。这些牙冠是3d打印出来并送到患者手中的。使用数字三重扫描技术评估边缘和内部差异和咬合接触。统计学分析采用配对样本的两个单侧t检验来评估两种方法的冠准确性(α = 0.05)。结果:两种方法制备的冠边缘间隙在颊、中、远端均相等;然而,在舌区,GAID方法产生了更高的边际差异(P < 0.001)。对于内部间隙,两种方法之间无显著差异。GAID法制作的冠与CCAD法制作的冠的咬合差异较大(P < 0.001)。结论:生成式人工智能制作的冠体与人工输入计算机设计方法制作的冠体吻合精度相当。虽然边缘和咬合差异在临床可接受范围内,但必须仔细注意自动设计结果,考虑各种牙齿准备形状,解剖结构和临床变化。

Fit accuracy of complete crowns fabricated by generative artificial intelligence design: a comparative clinical study.

Purpose: Designing restorations remains challenging because the process is time-consuming and requires operator skill and experience. This clinical study evaluated the fit accuracy of polymerized complete crowns fabricated using a web-based 3D generative artificial intelligence design (GAID) method compared to crowns fabricated using a conventional computer-aided design (CCAD) method.

Materials and methods: Sixty-two patients requiring complete crowns in maxillary and mandibular premolars and molars were enrolled. After tooth preparation, digital impressions were taken using an intraoral scanner. Two crowns per patient were designed: one used a web-based automatic 3D GAID software program, and the other used a standard human-driven CCAD software program. The crowns were 3D-printed and delivered to the patients. Marginal and internal discrepancies and occlusal contacts were evaluated using a digital triple scan technique. Statistical analysis used two one-sided t-tests for paired samples to assess crown accuracy in both methods (α = .05).

Results: Marginal gaps of crowns made by both methods showed equivalence in the buccal, mesial, and distal regions; however, in the lingual region, the GAID method produced higher marginal discrepancies (P > .001). Regarding internal gaps, no significant difference was observed between the two methods. Crowns produced by the GAID method exhibited larger occlusal discrepancies than those made by the CCAD method (P < .001).

Conclusion: The fit accuracy of crowns fabricated using generative artificial intelligence was equivalent to those produced using the manual-input computer design method when the margins were well defined. While marginal and occlusal discrepancies were within clinically acceptable range, careful attention must be given to automated design outcomes, considering various tooth preparation shapes, anatomical structures, and clinical variations.
