The records of 500 consecutive Saudi Arabian patients referred for orthodontic treatment were examined clinically and cephalometrically for Class III malocclusion. A control group was drawn at random from the same sample. The incidence of Class III was 9·4 per cent, with mandibular prognathism being the commonest presentation of the malocclusion. The upper and lower incisors exhibited a marked degree of dentoalveolar compensation, on dental bases having mean values of SNA—78·77° and SNB—81·17°. The maxillary length was reduced, as were the saddle and maxillary—mandibular plane angles. The gonial angle (ArGoMe), anterior and posterior facial heights, and mandibular lengths (ArGo, ArPo) were all significantly larger than the control group. The cephalometric values of the control group showed the increased tendency to bimaxillary protrusion in the Saudi Arabian sample.

BACKGROUND Facial prognathism may be because of prognathic maxilla, prognathic mandible or aggregate of both. Numerous studies performed to diagnose a single morphological feature commonly producing protrusive relationship, revealed that ‘a single morphological feature does not ordinarily produce a protrusive relationship. Existence of structural imbalance in one area also affects the nature of balance in other areas. A number of separate but inter-related cause and effect factors tend to augment each other in a cumulative and composite manner. Effect of marked discrepancy of an individual’s facial part could be cancelled or nullified by deviation of another part in opposite direction, ultimately resulting in good facial harmony. In this study by means of cephalometric roentgenography, the relation between Angle SNA and Angle NSAr was assessed in Vidharbhites, having normal occlusion, Class II division I and class III malocclusion. METHODS 40 individuals of normal occlusion, Class II division I and Class III Malocclusion, each between 16 and 25 years were analysed. These subjects were selected from patients reporting the outpatient department of Government Dental College, Nagpur. Statistically correlation between angles SNA and NSAr at level of significance 5 % was assessed. RESULTS After data collection a thorough observation & analysis was done and co-relation coefficient between SNA angle & NSAr (F--1.054 M--0.7981), also standard deviation of angular cephalometric measurement between males & females was found out in the population, leading to discussion on topic ‘Facial prognathism is due to maxillary prognathism, mandibular prognathism or combination of both’. In Females SNA was found to be 81 - 800 1.91310 and in males SNA was 82.1660 4. 380 respectively. CONCLUSIONS The results inferred that “Marked part of variation in Angle SNA can be explained by variation in Angle NSAr. KEY WORDS Angle SNA, Angle NSAr, Correlation

Objective: This longitudinal retrospective cephalometric study was undertaken in an attempt to evaluate the effect of Class III activator on the soft tissue structures in subjects with skeletal Class III. Methods: The material consisted of cephalometric films of 26 Class III patients (13females and 13 males, with a mean age of 13.58±4.38 years). Each treated patient was matched before treatment with Class III subject for sex and age. Differences at T1 and T2 were examined using paired t-test. Results: After treatment the patients' soft tissue profile improved significantly compare with before treatment. Conclusion: Soft tissue changes were found in patients treated by Class III activator in skeletal Class III patients. Clinical relevance: Class III activator may be an efficient method to improving soft tissue facial profile in Skeletal Class III malocclusion.

Cephalometric Study

A retrospective cephalometric study investigated the differences in the skeletal pattern of the Class III malocclusion. Thirty Caucasian adolescents with an anterior mandibular displacement on closure were compared to an equal number without such a displacement before treatment, at the end of treatment and at least 1 year out of retention.
