Brief 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.

Outcome Measures

Primary Outcomes (1)

  • Fixed efficiency

    Fixed effective as the affected tooth loosening does not exceed the physiological degree of movement, X-ray examination periodontal membrane without widening without abnormal shadow of the root tip

    four weeks

Study Arms (2)

digital impression module

EXPERIMENTAL

In the experimental group, digital impressions and 3D printed models were used and fitted pads were made. Patients were instructed to wear the hinge pad for 24 hours, and x-rays were taken and intraoral examinations were performed at 2 weeks and 4 weeks.

Procedure: digital impression

ordinary impression group

ACTIVE COMPARATOR

The control group used alginate impression and plaster model infusion to make the model and make the fitting pad. Patients were instructed to wear the pad for 24 hours, and x-rays and intraoral examinations were taken at 2 and 4 weeks.

Procedure: alginate impression

Interventions

3D printed models after digital impressions

digital impression module

Alginate impressions after plaster model infusion to make models
