目的就传统取模的治疗方式和三维数字化取模的治疗方式在临床中应用的对比研究。方法随机收集临床131例行固定义齿修复患者,均采取印膜材取模石膏灌制模型制作义齿和口内3 Shape数字化扫描后制作的义齿进行临床比较。结果临床中有79例患者采用了数字化模型所制作的义齿,52例患者采用了传统治疗方式所制作的义齿。两组数据进行统计学分析,显示:两种治疗方式有显著性差异。结论临床中经口内数字化扫描取模制作的义齿适应性优于传统印模材取模制作的义齿。
Objective To compare the clinical application of traditional modal treatment and three-dimensional digital modal treatment. Methods A total of 131 patients undergoing fixed prosthesis were collected randomly, and the denture made by printing and die-casting cast gypsum irrigation model and digital denture made by digitizing 3 Shape in the mouth were collected for clinical comparison. Results In the clinic, 79 patients used dentures made by digital models and 52 patients used dentures made by traditional treatments. Two groups of data for statistical analysis showed that: the two treatment methods were significantly different. Conclusions The denture adaptability obtained by digital intracamera scanning in clinical practice is better than that of the traditional impression material.
