ABSTRACT

The purpose of this study was to identify the cephalometric skeletal morphological features of anterior open-bite [AOB] in adult Pakistanis. It was a cross sectional descriptive study having quantitative study design. Lateral cephalograms of 30 pre treatment anterior open-bite patients with the age range 17 to 27 years, coming to the department of Orthodontics were taken [18 females and 12 males]. Subjects of study sample were clinically diagnosed as having open bite.In addition the subjects were considered as having skeletal AOB when SN-GoGn angle was equal to or more than 32.5 degree. Ten linear and angular measurements were recorded. The results showed significantly increased values of linear measurements [PHF, AFH, UFH] and angular measurement[SN-GoGn].One angular measurement[SN-PP] was closer to the mean Caucasian sample values but there was more obliquity to the Gonial angle. The ratio PFH/AFH was small as compared to white anterior AOB subjects. Sexually dimorphic variables were also identified by independent sample t-test

ABSTRACT

Orthodontic treatment can improve mastication, speech and appearance, as well as overall health, comfort, and self-esteem. However, like many other interventions, orthodontic treatment has inherent risks and complications. Best way to avoid orthodontic treatment complications is to stay away from orthodontic appliances. Thus, if correcting malocclusion is to be of benefit, the advantages it offers should outweigh any possible damage. It is also important to implement risk control procedures during and after orthodontic treatment. Patient selection always plays a vital role in minimizing risks. In this article two cases illustrate the effective treatment in class 2 div 1 malocclusion with single arch treatment. This approach may reduce risk of orthodontic treatment. Observational Study. This study was conducted at the Orthodontics Dept., Islam Dental College, Sialkot. She 22 year old female having history of thumb sucking presented with class II incisors, canines and molars relationship on skeletal class II bases and convex profile. She also have anterior dental open bite with low vertical skeletal relationship.[pre-treatment photographs a-f]. All teeth are erupted except 3[rd] molars at [OPG][Pre-treatment radiographs I]. Cephalometrically Skeletal class 2 with low angle and bimaxillary dental proclination [Pre-treatment radiographs j]. Single arch treatment can be use in selected class 2 cases, where lower arch can be accepted as such, which can give maximum wanted effects of esthetic and function with minimum treatment
