ABSTRACT

Altuğ Type Maxillar Expander and Distalization Appliance Part 1 Sagittal Dimension Evaluation Altuğ Type Maxillar Expander and Distalization appliance, which is composed of an intraoral acrylic appliance and a combined headgear, is used to restrict maxillary sagittal growth and expand maxilla to koordinate Angle Class I occlusion. Second used of this aplliance is to distalize the maxillary premolar and molar teeth bodily at the same time.The aim of this study is to examine the skeletal , dentoalveolar and soft tissue effects of the Altuğ Type Maxillar Expander and Distalization appliance. The study material consisted of lateral cephalometric and hand-wrist films taken from 30 individuals of the treatment group before and after treatment and from the 17 individuals of the control group before and after the control period. The statistical significance of the changes in the measurements during the observation period of each patient in both groups was determined by paired t-test. The statistical significance of the differences between the treatment and the control groups was compared by Student's t-test. It has been observed that by the effect of Altuğ Type Maxillar Expander and Distalization appliance maxillary sagittal growth was restricted and transversally expanded and all the maxillary posterior teeth were distalized at a considerable degree. During treatment, some amount of distal tipping was seen at the maxillary premolar and molar teeth and extrusion of the posterior teeth was restricted.
