View clinical trials related to Malocclusion, Angle Class III.
Filter by:twenty-four patients with dentoskeletal deformity of class III will be divided equally into two groups and will be subjected to orthognathic surgeries group A; will be treated by mandibular setback surgery while group B will be treated with bimaxillary orthognathic surgery in the form of mandibular setback and maxillary advancement surgeries. the total pharyngeal airway will be measured on lateral cephalometric radiographs, integrating retro-palatal and retro-glossal area, and statistically will be compared preoperative, immediate postoperative, and at 6 months post-surgically
The aim of this randomized controlled trail is to compare the efficacy of an intraoral device (the Carriere® Motion 3D™ Class III Appliance) with the facial mask for the early treatemnt of Class III malocclusion. This is a monocentric, parallel, controlled trial with blinded examiner.
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.
A clinical study to test the capability of the mini-screws inserted in the Mandibular buccal shelf area as an anchorage unit to distalize mandibular first molar for correction of mild to moderate Class III cases. The second aim was to detect if there is a difference in the amount of distalization in the presence of unerupted mandibular third molars, using the same technique.
The aim of this study is to evaluate the levels of pain, discomfort and acceptance between two treatment modalities of Class III correction of growing patients in the late mixed dentition period.
The study product is a Cold Ablation Robot-guided Laser Osteotome (CARLO®) robotic surgery device. It is a device that removes hard tissue such as bone by means laser ablation - it is therefore an alternative to Piezo-Electric osteotomes and/or oscillating saws or other mechanical instruments for bone cutting. In this study, the CARLO device is integrated with a computer-assisted pre-operative planning and intra-operative navigation, and will be used for Patients requiring an orthognathic procedure with a mid-face osteotomy, for whom a procedure plan is defined based on preoperative imaging.
Two groups with mandibular prognanthism indicated for mandibular setback by intraoral vertical ramus osteotomy . first group will fixed with maxillomandibular fixation and the second group will fixed by customized plate
This study evaluates the dentoskeletal effects produced by two maxillary protraction protocols in adolescent patients. Half of participants will be treated with a tooth-borne and tooth-bone-borne expanders as anchorage in the maxillary arch. Miniscrews will be used as anchorage in the mandibular arch for both groups.
This experimental study aims to evaluate the efficiency of the Modified Fixed Mandibular Retractor Appliance in the treatment of skeletal class III malocclusion. The study sample will consist of 44 patients with skeletal class III malocclusion. The sample will be allocated randomly into two groups: experimental group and untreated control group. The soft and hard tissue changes will be assessed using lateral cephalometric radiographs before the treatment and after obtaining 3mm positive overjet.
The investigator will assess the inverted sequence approach in the treatment of class III patient undergoing bimaxillary orthognathic surgery
