Biomechanical evaluation between orthodontic attachment and three different materials after various surface treatments: A three-dimensional optical profilometry analysis
(2019) Kurt, Irem; Cehreli, Zafer Cavit; Ozcirpici, Ayca Arman; Sar, Cagla; 30855180
Objectives: To determine the best bonding method of orthodontic attachment among monolithic zirconia, feldspathic porcelain, hybrid porcelain, and the impact of surface-conditioning methods using a three-dimensional optical profilometer after debonding. Materials and Methods: 56 feldspathic porcelain, 56 monolithic zirconia, and 56 hybrid porcelain samples were divided into four surface treatment subgroups: (1) hydrofluoric (HF) acid etch + silane, (2) Al2O3 sandblasting + silane, (3) silicoating (SiO2), and (4) diamond bur + silane. The specimens were tested to evaluate shear bond strength (SBS). Residual composite was removed after debonding. Three-dimensional white-light interferometry was used to obtain quantitative measurements on surface roughness. Results: The highest SBS value was found for the HF acid-etched feldspathic porcelain group. The average surface roughness values were significantly higher in all material groups in which diamond bur was applied, while roughening with Cojet provided average surface roughness values closer to the original material surface. Conclusions: Variations in structures of the materials and roughening techniques affected the SBS and surface roughness findings.
Dental and Dentofacial Problems in A Female Child With Toriello-Carey Syndrome: Changes in 3 Years
(2016) Tirali, Resmiye Ebru; Ilhan, Banu; Sar, Cagla; Cehreli, Sevi Burcak; 0000-0001-6487-3984; 0000-0003-4966-9779; 27159668; HZK-4947-2023; AAD-2907-2020; AAD-6138-2021
Toriello-Carey syndrome is a rare disease whose clinical manifestations are midline facial defects, laryngeal and pharyngeal hypoplasia, cardiac defect, and corpus callosum hypoplasia. Literature states that clinical manifestations are more evident in males. This is the second report in the literature which describes the dental and dentofacial features in an 8-year-old female patient with Toriello-Carey syndrome.
Dentofacial Effects of Skeletal Anchored Treatment Modalities For The Correction of Maxillary Retrognathia
(2014) Sar, Cagla; Sahinoglu, Zahire; Ozcirpici, Ayca Arman; Uckan, Sina; https://orcid.org/0000-0003-4966-9779; https://orcid.org/0000-0002-9250-3689; 24373654
Introduction: The aim of this clinical study was to investigate the skeletal, dentoalveolar, and soft-tissue effects of 2 skeletal anchorage rationales for Class III treatment compared with an untreated Class III control group. Methods: Fifty-one subjects who were in the prepubertal or pubertal growth period were included in the study. In group 1 (n = 17), facemasks were applied from miniplates placed in the lateral nasal walls of the maxilla, and intermaxillary Class III elastics were applied from symphyseal miniplates to a bonded appliance on the maxilla in group 2 (n = 17). These skeletal anchored groups were compared with an untreated control group (n = 17). Lateral cephalometric radiographs were obtained at the beginning and the end of the observation periods in all groups and analyzed according to the structural superimposition method. Differences between the groups were assessed with the Wilcoxon signed rank test or the paired-samples t test. Results: The treatment periods were 7.4 and 7.6 months in groups 1 and 2, respectively, and the untreated control group was observed for 7.5 months. The maxilla moved forward by 3.11 mm in group 1 and by 3.82 mm in group 2. The counterclockwise rotation of the maxilla was significantly less in group 1 compared with group 2 (P < 0.01). The mandible showed clockwise rotation and was positioned downward and backward in the treatment groups, and it was significantly greater in group 2 compared with group 1 (P < 0.01). Changes in the maxillary incisor measurements were negligible in group 1 compared with group 2. A significant amount of mandibular incisor retroclination was seen in group 1, and a significant proclination was seen in group 2. The maxillomandibular relationships and the soft-tissue profiles were improved remarkably in both treatment groups. Conclusions: The protocols of miniplates with facemasks and miniplates with Class III elastics offer valid alternatives to conventional methods in severe skeletal Class III patients. However, the 2 maxillary protraction protocols demonstrated significant skeletal and dentoalveolar effects. The miniplate with facemask protocol is preferred for patients with severe maxillary retrusion and a high-angle vertical pattern, whereas in patients with a decreased or normal vertical pattern and retroclined mandibular incisors, miniplates with Class III elastics can be the intraoral treatment option. Therefore, the exact indication of the procedure should be considered carefully.
Psychosocial and Functional Outcomes of Orthognathic Surgery: Comparison with Untreated Controls
(2015) Sar, Cagla; Soydan, Sidika Sinem; Ozcirpici, Ayca Arman; Uckan, Sina; 0000-0002-9250-3689
Objectives: Orthognathic surgery is a procedure for patients with dentofacial deformities and provides dramatical dentofacial and psychological alterations. The aim of this controlled study was to evaluate how orthognathic surgery affects patients' psychosocial well-being and compare them with patients having dentofacial discrepancies and with individuals who do not have any skeletal discrepancies. Methods: Hundred and sixty-three adult individuals were included in this study as three groups: patients who underwent orthognathic surgery, patients having skeletal discrepancies and individuals who do not have any skeletal discrepancies. Patients in all groups were asked to fill out two questionnaires concerning the psychological and physical status of the patients at that moment and additional questions were asked to patients in post-surgical phase regarding post-surgical satisfaction. Categorical variables were statistically evaluated by Fisher Exact and chi-square tests. Results: Patients who were going to seek orthognathic surgery were significantly concerned about their dentofacial appearance, body image and psychosocial status when compared with patients in the post-surgical phase and the individuals who did not have skeletal discrepancies. The results of the patients who underwent orthognathic surgery were approximated to the results of non-patient control group and had high degrees of satisfaction with improvement in appearance brought about by surgery at 6-month post-operatively. Conclusion: Following orthognathic surgery, patients had better psychosocial status when compared to patients without skeletal deformities. Patients in the pre-surgical phase were not only functionally but also psychosocially the least satisfied group of individuals. (C) 2014 Asian AOMS, ASOMP, JSOP, JSOMS, JSOM, and JAMI.
