OBJECTIVE To analyze the reliability and reproducibility of a simplified method for analysis of dental angulation using digital photos of plaster dental casts. METHODS Digital and standardized photographs of plaster casts were performed and posteriorly imported to an angle reading graphic program in order to have measurements obtained. Such procedures were repeated to evaluate the random erro...

The intrusion of an overerupted maxillary molar using traditional orthodontic treatment is a real challenge. The aim of this study was to investigate the envelope of intrusive movements of a maxillary molar in cases using mini-implants as anchorage with partial or full-mouth fixed edgewise appliances. The cusp tips of the pretreatment and postintrusion dental casts were recorded by a three-dime...

The fundamental factors in the diagnosis in the orthodontic treatment are the spacing condition, tooth size, arch form and its dimensions. Plaster model analysis is a time-consuming procedure. Dividers, calipers, and Boley gauges have provided the standart of measurement against which newer methods have been evaluated [1]. Various scanning techniques, including laser scans, structured light, de...

Relationships between changes in arch perimeter and arch width resulting from rapid palatal expansion with the Hyrax appliance were analyzed with the use of dental study casts of 21 adolescent patients. Photographs and measurements from the dental casts obtained before treatment and approximately 3 months after stabilization were used. Regression analysis indicated that changes in premolar widt...

The aim of this study was to evaluate the effects of an asymmetrical maxillary expansion (AMEX) appliance. Patients with true unilateral posterior crossbites were included in the study. The treatment group consisted of 18 patients who had a mean age of 14 +/- 2.3 years. Treatment effects were evaluated on posteroanterior radiographs, dental casts, and photographs of the dental casts. All unilat...
