NCT ID: NCT05216874 Recruiting - Clinical trials for Class III Malocclusion

The Effect of Splint Usage in Laterognathic Cl III Orthognathic Surgery Patients

TMJ
Start date: January 13, 2022
Phase: N/A
Study type: Interventional

It is crucial to maintain the anatomic condylar positions during orthognathic surgery. Condylar positions are affected directly under general anesthesia because of joint and muscle relaxation. Possible unwanted changes in the joint position may cause incorrect positioning of the jawbones. This could affect the success of the surgery in terms of function and facial aesthetics causing the need for a second surgery. Our aim is to evaluate whether the use of MR Splint has a statistically significant effect on muscle relaxation-induced condyle position deviations under general anesthesia in Class III Laterognathia patients.

NCT ID: NCT04354116 Recruiting - Clinical trials for Cleft Lip and Palate

MARPE in Patients With Cleft Lip and Palate

Start date: January 10, 2020
Phase: N/A
Study type: Interventional

The objective of this randomized controlled study will be to evaluate the dental and skeletal effects of maxillary protraction with a facemask, associated with MARPE and Class III elastics in patients with unilateral cleft lip and palate (CLP) with maxillary retrusion, compared to HYRAX type maxillary expanders. The investigators will examine differences in treatment times, along with skeletal, dental and soft tissue changes.

NCT ID: NCT04117360 Recruiting - Malocclusion Clinical Trials

Orthognathic Speech Pathology: Phonetic Contrasts of Patients With Dental Discrepancies Pre- and Post-Treatment Analyses

OSP
Start date: September 11, 2019
Phase:
Study type: Observational

The investigators are studying how speech is effected by jaw and tooth position in jaw surgery patients. Eighty percent of our jaw surgery patients have speech pathologies, compared to five percent of the general population, but speech pathologists do not understand why. The investigators hypothesize that open bites and underbites prevent most patients from being able to pronounce words normally and surgical correction will lead to improvement in speech. Patients will be audio recorded speaking and patients' tongue gestures ultrasound recorded before and after their jaw surgeries to observe what changes occur in their speech and tongue movements.
