About

This study conducted a randomized controlled clinical trial to evaluate the effect of the the therapeutic position of the anterior repositioning splint determined by VTO analyse compared with traditional method for the treatment of the Anterior Disk Displacement with Reduction of the Temporomandibular Joint.

Full description

A randomised clinical trial was conducted with 20 patients diagnosed with ADDWR through RDC/TMD and they were randomly allocated into the group 1(traditional group):the therapeutic position of the ARS were determinded by the "minimum protrusive position",which was the traditional method to fabricate the anterior repositioning splints;group2(digitial group): the therapeutic position of the ARS were determinded by the VTO analyse,first,the participants were constructed to take CBCT and MRI scans,the ideal therapeutic position of the ARS were located in which the temporomandibular joint space distribute well and the condylar recapture the disc,the dentist could determine the amount of condylar movement and performed VTO analyse by assessing the CBCT and MRI scans ,then it could easily realize the final condylar movements with the application of the dental articulator.

They were followed-up in the baseline,1 month,2 and 3 months after the inserted of the splints using the Craniomandibular Index (CMI) for temporomandibular joint function and PHQ-9,GAD-7 for psychological assessments,the tmj space and disc-condylar angle were measured through the CBCT and MRI scans,before and after ARS therapy.

---

20 participants in 2 patient groups

the therapeutic position of the ARS were determinded by the "minimum protrusive position"

Active Comparator group

Description:

the therapeutic position of the ARS were determinded by the "minimum protrusive position",which was the traditional method to fabricate the anterior repositioning splints,the patients were instructed to protrusive the mandible in a therapeutic position in which the click is eliminated.

Treatment:

Procedure: therapeutic position of the anterior repositioning splints

the therapeutic position of the ARS were determinded by the VTO analyse

Experimental group

Description:

the therapeutic position of the ARS were determinded by the VTO analyse,first,the participants were constructed to take CBCT and MRI scans,the ideal therapeutic position of the ARS were located in which the temporomandibular joint space distribute well and the condylar recapture the disc,the dentist could determine the amount of condylar movement and performed VTO analyse by assessing the CBCT and MRI scans ,then it could easily realize the final condylar movements with the application of the dental articulator.

Treatment:

Procedure: therapeutic position of the anterior repositioning splints
