    Evaluation of Soft Tissue Differences between Different Skeletal Anomalies in Sagittal Direction
    (Aves Press Ltd, 2008) Gunduz-Arslan, Seher; Keskin, Kamile; Akkurt, Abhm; Devecioglu-Kama, Jalen
    The aim of this study is to evaluate the cephalometric soft tissue differences of early adults in sagittal direction. Our study consists of 63 patients' lateral cephalograms who referred to University of Dicle Faculty of Dentistry for orthodontic treatment (Class I: 23, Class II: 19, Class III: 21). The main age was 19.28 years. 24 angular and linear measurements were performed in cephalometric radiographs of patients. According to Mann Whitney U test only the PMA angle showed statistically significant differences in comparison of Class I and II patients. In comparison of adult Class I and III patients; Class III patients were showed greater values in; A-UpSulcus, Uplip-E Line, MLA and PMA parameters. In comparison of adult Class II and III patients with normal vertical pattern, PTV-Nasaltip and PTV-UpSulcus parameters were greater for Class II patients. Regardless of abnormality in skeletal tissue of underlying soft tissue it still has a great tendency to return to normal. We observed that compensatory mechanism works remarkably especially for soft tissues of Class II anomaly groups.

    Soft Tissue Profile Changes Associated with the Treatment of Class III Anomalies with Maxillary Constriction and Retrusion
    (Aves Press Ltd, 2007) Gunduz-Arslan, Seher; Devecioglu-Kama, Jalen; Genc, Celal; Dari, Osman
    The aim of this study was to evaluate soft tissue profile changes of Class III patients with maxillary constriction and retrusion with area measurement method, following rapid maxillary expansion (RME) + Petit type face mask and fixed orthodontic appliance treatment. Cephalometric radiographs taken from 37 treated and 21 untreated Class III patients were used for this study. These radiographs were taken before and after treatment in test and control groups. Soft tissues were traced on these cephalometric radiographs. Nose, upper and lower lips, chin and free space areas were measured between the E-line and Juanita line. T-tests used to assess these parameters statistically. Significant changes in nose, upper lip, chin and free space areas were observed in the treatment group. The only mean increase occurred in chin area in control group. Increases of nose and upper lip areas were significantly different between treatment and control groups (P<0.001). Present study shows that the treatment with, RME + petit face mask and fixed appliances have an important role in profile improvement.

    Treatment of an Adult Patient with Skeletal Class II and Unilateral Cross-bite
    (Aves Press Ltd, 2007) Gunduz-Arslan, Seher; Devecioglu-Kama, Jalen; Akkurt, Atilim
    The purpose of this case report is to represent the treatment of adult sketetal Class II malocclusion with posterior cross-bite. Our patient was 24.2 years old a female. According to intraoral observation, a maxillary protrusion and posterior cross-bite were determined with Angle Class I motar relationship. Due to the cephalometric analysis, ANB and SNGoGn angles were 7 degrees and 50 degrees respectively. And also she had a Bolton discrepancy of 6 mm. The patient refused orthognathic surgery procedure, so her orthodontic problem was decided to achieve orthodontically without surgery. For elimination of posterior cross-bite rapid maxillary expansion (RME) appliance was used, however maxillary expansion could not accomplished. Thus, a quad-helix was used for maxillary expansion with an occlusal bite plane on the upper left molars side to prevent the expansion on this side. After expansion, fixed orthodontic appliances were applied with an occipital headgear. The cooperation of our patient was quite well. She has been wearing the extraoral appliances more than asked. Because of this a baldness which called traumatic areata were occurred on her occipital scalp region. Bolton discrepancy was compensated with a little amount of diastema behind the upper canines. Finally; maxillary protrusion and posterior cross-bite were treated with 3,5 degrees reduction of vertical dimension. At the end of the treatment, an acceptable occlusion and facial esthetic were obtained
