OBJECTIVE The objective of this study was to investigate the differences in masticatory efficiency among patients with different Angle's classes of malocclusion and to assess the correlation between masticatory efficiency and the occlusal contact area. METHODS The mixing ability index (MAI) was calculated for measuring masticatory efficiency of 61 adult patients according to Angle's classific...

This study evaluated the relationship among malocclusion, number of occlusal pairs, masticatory performance, masticatory time and masticatory ability in completely dentate subjects. Eighty healthy subjects (mean age = 19.40 ± 4.14 years) were grouped according to malocclusion diagnosis (n = 16): Class I, Class Class II-2, Class III and Normocclusion (control). Number of occlusal pairs was deter...

background: the extraction of teeth for orthodontic purpose has always been a controversial subject in the speciality. the aesthetics impact of the soft-tissue profile might play a key role in deciding on premolar extraction or non-extraction (ne) treatment, particularly in borderline patients. the purpose of this cephalometric study was to examine the soft-tissue treatment effects of class ii ...

OBJECTIVE To determine the prevalence of tooth size discrepancies (TSDs) in an Irish orthodontic population among different malocclusion groups. MATERIALS AND METHODS From 850 pretreatment sets of orthodontic models at a university clinic, 240 were selected with 30 female and 30 male sets for each malocclusion (Class I, Class II division 1, Class II division 2, and Class III). Digital models ...

A study was undertaken to determine the prevalence of malocclusion in Jaipur city, India. A total of 700 subjects, in the age group of 16-26 years were divided into five groups of normal occlusion, Angle's Class I, Class II Div 1, Class II Div 2 and Class III malocclusion. The results revealed that the prevalence of malocclusion was 66.3%, with the majority of them having Class I malocclusion (...

Early treatment for Class II malocclusion was undertaken with the objective of correcting skeletal disproportion by altering the growth pattern. A case of Class II, Division 1 malocclusion in the mixed dentition was corrected to Class I molar relationship using orthopedic cervical headgear, with nonextraction edgewise therapy. Cephalometric analysis indicated a reduction in the maxillomandibula...

UNLABELLED Four premolar extractions is a successful protocol to treat Class I malocclusion, but it is a less efficient way when compared with other Class II treatment protocols. OBJECTIVE The objective of this study was to evaluate the influence of anteroposterior discrepancy on the success of four premolar extractions protocol. For that, treatment efficiency of Class I and complete Class II...

AIM The aims of this study were to evaluate the dental changes brought about by activator and activator headgear combination (ACHG) and to determine whether we can achieve control over the lower incisor proclination which is a side effect of using functional appliances; or not, while treating cases of skeletal class II malocclusions. METHODS Lateral cephalograms of 45 skeletal class II divisi...

A number of authors have suggested that there is a relationship between the degree of cranial base flexion and type of malocclusion, with the angle becoming increasingly obtuse from class III through class I to class II subjects. A retrospective cephalometric study was carried out to examine the contribution of cranial base angle in the four groups of malocclusion as classified by the British S...
