Detailed Description

The relationship among occlusion, condylar position and temporomandibular disorders (TMDs) has been part of an extensive discussion in the dental field. There is a strong belief that the discrepancy between the centric relation (CR) and the intercuspal position (ICP) could predispose to the presence of TMDs . It was suggested in the past in the earlier studies that TMD is more common among the individuals who have Angle class II and class III , malocclusion , open bite , and cross bite . In the 1990s, studies suggested that some occlusal and skeletal characteristics as anterior open bite, unilateral posterior crossbite, overjet greater than 6-7mm, absence of five or more posterior teeth and CR to maximum intercuspation (MI) discrepancy greater than 2mm could be considered occlusal risk factors for TMDs . In their study, Oyetola et al. reported that 25% of the evaluated TMD patients had malocclusion Yet, recently with studies and systematic reviews , this idea ( alocclusion is the main cause of TMD) started to lose its support, and many studies showed that sensitivity to nociceptive stimulations and psychological factors are of more importance in the etiology of TMD

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Prevalence of ADDwR in patients with class III malocclusion
Time Frame: baseline

baseline

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Prevalence of ADDwR in patients with class I and class II malocclusion
Time Frame: baseline
lateral cephalometry will be taken for patients with TMDs and then measurements will be done to calculate SNA and SNB to see Prevalence of ADDwR in patients with class I and class II malocclusion
