During restorative dental procedures, complete control over the operative site is critical for patient comfort, safety, and the operator's access and visibility. The success of a fixed prosthesis depends on accurate impression making of the prepared finish lines on the abutment teeth. To optimise long-term outcomes for the fixed restoration, gingival retraction techniques should be used to decrease the marginal discrepancy among the restoration and the prepared abutment. Accurate marginal positioning of the restoration along the prepared finish line of the abutment is essential for therapeutic, preventive, and aesthetic purposes.
在牙齿修复手术过程中，对手术部位的完全控制对于患者的舒适度、安全性以及术者的操作便利性和视野至关重要。固定修复体的成功取决于对基牙预备完成线的精确印模制取。为了优化固定修复的长期效果，应采用牙龈退缩技术来减少修复体与预备基牙之间的边缘差异。修复体沿基牙预备完成线的精确边缘定位对于治疗、预防和美观目的而言至关重要。
