Öğe Arch Dimension Changes Associated with the Treatment of Class III Cases(Aves Press Ltd, 2007) Gunduz-Arslan, Seher; Deveciolu-Kama, Jalen; Ozer, Torun; Dari, OsmanThe aim of this study was to investigate the dentoalveolar changes associated with the treatment class III anomalies characterized with maxillary narrowness and retrusion. Orthodontic study models of 20 patients before and after treatment were used. Distance and area measurements of these models are considered. The study models of 20 patients that were not treated served as a control group. Fourteen parameters were investigated on study models. Paired t test was used in group comparisons and independent student t test was used in between group comparisons. Palatal shelf area measurement in the premolar region was increased in both groups but the increases of the treatment group were larger (P<0.001-P<0.05). The changes in the other parameters were different from each other. Upper and lower arch perimeters (P<0.05), lower canine to canine distances (P<0.01), upper (P<0.001) and lower (P<0.05) premolar to premolar distances, palatal shelf area measurements in the molar region (P<0.001) increased significantly but premolar angulations (P<0.05) decreased significantly. Dentoalveolar changes were occurred as a result of modifications in the direction of growth.Öğe 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, JalenThe 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.Öğe Impact of Buccal Corridors on Smile Esthetics(Aves, 2011) Basaran, Guvenc; Veli, Ilknur; Genc, Celal; Gunduz-Arslan, SeherAim: The purpose of the present study was to investigate the influence of buccal corridors on smile esthetics. Subjects and Methods: For this purpose, 10 individuals with following criteria were included to this study; to have an esthetic smile arc, no excessive gingival exposure, ages between 18 and 30 years and equal distribution of the sexes. These criteria and only the perioral photographs were used to limit the scope of the variables and to decrease the dilution of the results. A photo editing software was used to produce 5 varying sizes of buccal corridors and the pictures were classified as Narrow smile, Medium-narrow smile, Medium smile, Medium-broad smile and Broad smile. Altered five smile images of the individuals were showed to the panels consisted of orthodontists, prosthodontists, general dentists, lay people and drawing artists each numbered 10 juries. They were asked to rate that five images from 1 to 5. ANOVA and Tukey tests were used to make a statistical analysis. Results: All of the panels evaluated the smile images in the same manner. The broader the smile it is the more attractive. The most attractive smile was the broad smile and the least attractive was the narrow smile. All panel groups evaluated the smile images in the same manner and there were not statistically significant differences between the groups. Conclusion: These results indicate that; to gain an esthetic smile after orthodontic treatment, clinician must avoid causing broad buccal corridors.Öğe The Level of IL-1? In Orthodontically Treated Osteopototlc Rats(Aves Press Ltd, 2008) Gunduz-Arslan, Seher; Kaya, Filiz Acun; Arslan, Huseyin; Kaya, Can Ayhan; Hamamci, OrhanThis study aims to evaluate the levels of IL-1 beta, in samples taken from the gingival crevicular fluid (GFU) of osteoporotic rats during orthodontic treatment. 33 adult female Spraque-Dawley rats were divided into 2 groups. (15 control and 18 study group) In study group bilateral ovariectomy was carried out to create osteoporotic rats. And also in control group sham operation was carried out. Two months following the operation, an open coil spring applying 10g force, was placed actively between the upper incisors of the rats Shortly after activation, samples were taken from the gingival crevicular fluid from the vestibular surface of appliance fixed teeth on the 3rd,7th and 10th days. Samples were analyzed biochemically. The statistical analysis of data acquired from the samples was carried out by using ANOVA test. The evaluation of the changes between the groups was carried out by using Mann Whitney U test. It was observed that the level of IL-1 beta were high on the 3rd and 7th in both groups. In the comparison of control and study groups there were significant differences between the working days.Öğe Nonsurgical Correction of Severe Anterior Openbite Malocclusion(Aves Press Ltd, 2008) Gunduz-Arslan, Seher; Ozant, Ahmet; Hamamci, OrhanThis case report describes the treatment of a 17 years and 2 months old male patient presenting vertical discrepancy, with severe anterior open bite and Class II subdivision malocclusion with a history of dummy sucking and mouth breathing. The patient showed a straight type in lateral profile and his lips were incompetent at rest. He had an anterior open bite of 8 mm, an overjet of 6 mm. In consultation with the patient and his parents, a nonsurgical therapy was elected and the goals were; to close the anterior open-bite and to achieve a good function and esthetic. By extraction of maxillary and the first molar, usage of maxillary bite plate with occipital headgear and usage of the rectangular arch wire with reverse curve of Spee applied to the mandible and increased curve of Spee (0.016x0.022 '') rectangular arch wire applied to the maxillary arch open bite was eliminated.As a result,the patient was treated successfully with suitable nonsurgical treatments.Öğe 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, OsmanThe 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.Öğe Treatment of an Adult Patient with Skeletal Class II and Unilateral Cross-bite(Aves Press Ltd, 2007) Gunduz-Arslan, Seher; Devecioglu-Kama, Jalen; Akkurt, AtilimThe 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
