双侧唇腭裂新生儿数字化模型与硬石膏模型的比较

目的： 比较双侧唇腭裂新生儿口内扫描数字化模型和硅橡胶制取灌注的超硬石膏模型的可靠性和稳定性。方法： 收集19例双侧唇腭裂新生儿病例,分别制取口内扫描数字化模型和硅橡胶取模超硬石膏灌注模型,对上颌牙槽骨长度、上颌牙槽骨宽度、腭裂宽度及上颌中线偏斜量等指标进行测量。采用SPSS 24.0软件包对测量结果进行统计学分析。结果： 2种方法上颌牙槽骨长度、上颌牙槽骨宽度、腭裂宽度及上颌中线偏斜量3次测量间均无统计学差异（P>0.05）,2种方法的测量值无统计学差异（P>0.05）。结论： 双侧唇腭裂新生儿口内扫描获取的数字化模型与硅橡胶取模超硬石膏灌注获取的石膏模型各测量项目之间无显著差异。口内数字化扫描操作过程简便,可以提高诊疗效率,新生儿承受痛苦少,风险小,可广泛用于唇腭裂患儿的研究、诊断分析及临床治疗。

Comparison of digital model and dental plaster model in evaluation of bilateral cleft lip and palate

PURPOSE: To compare the reliability of digital model and plaster model on evaluation of bilateral cleft lip and palate. METHODS: Nineteen pairs of digital and plaster model obtained from bilateral cleft lip and palate patients were measured, including nine measurements, such as maxillary alveolar length, width, cleft width, the deviation of maxillary middle line. One-way ANOVA was conducted for statistical analysis with SPSS 24.0 software package. RESULTS: There was no significant difference between the repeated measurements of the two types of models, there was no significant difference in the measurements between two types of models used in clinic. CONCLUSIONS: Both methods are suitable for evaluation of bilateral cleft lip and palate patients. Compared with conventional plaster model, digital model provides a safer and convenient way to obtain useful information both for research and clinical need.
