Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
2. In the experimental group, digital impressions + 3D printed models were used and fitted pads were made; in the control group, alginate impressions + plaster model infusion were used to make models and fitted pads were made. The included subjects were routinely examined intraorally before and after treatment. Patients were instructed to wear the hinge pad for 24 hours and X-ray films were taken and intraoral examination was performed at 2 weeks and 4 weeks.
3. The observation indexes included： (1) operation time: operation time for the child's chair position, (2) comfort index: pain assessment of patients using visual analog scale, (3) efficacy indexes: a. tooth sensitivity, gingival margin irritation, and lip irritation were assessed using visual analog scale (VSA); B. fixation efficiency.
