托槽在数字化牙颌模型上位置与间接粘结转移后实际位置的一致性研究
Study on the consistency of the position of the brackets on the digital occlusal model and the actual position af-ter indirect bonding
摘要
Abstract
Objective To provide the experimental basis for the coherence of the indirect bond position by compar-ing the position of the bracket on the digital occlusal model and the position of the transfer to the initial plaster model. Methods Fifteen digitized models were selected for the brackets on the dental denture model, the brackets were trans-ferred to the initial plaster model by indirect bond transfer trays, The line distance between each bracket position in dig-ital dental model and initial plaster model was measured with OrthoRx software. Results The difference between the position of the orthodontic brackets and the position of the initial plaster model was less than 0.20 mm, and the differ-ence was statistically significant (P < 0.05). Conclusion The position of the bracket on the digital occlusal model is consistent with that of the original plaster model, which provides a theoretical basis for digital indirect bonding.关键词
