Application of Digital Impression Technology in Children's Dental Trauma

Status Recruiting

Clinical Trial Summary

We will Choose patients with tooth loosening caused by tooth trauma and requiring fix in the department of Pediatric Dentistry and emergency of Stomatology Hospital, Zhejiang University School of Medicine, from July 2022 to May 2025. These patients will be randomly divided into digital impression module (experimental group) and ordinary impression group (control group).The operation time, comfort index and efficacy index of the two groups were compared to investigate the advantages of digital impressions in the application of traumatic dental injuries in children.

Clinical Trial Description

1. Information on medical history, physical examination, and ancillary tests were collected and recorded by the pediatric dentistry and emergency department to determine the inclusion subjects, and the grouping was determined according to a randomized controlled design. 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. ;
