Publication Open Access Does surgically assisted maxillary protraction with skeletal anchorage and Class III elastics affect the pharyngeal airway? A retrospective, long-term study(2023-01-01) YILMAZ, HANİFE NURAY; Ozbilen E. O., Papaefthymiou P., YILMAZ H. N., Küçükkeleş N.© 2023 The Korean Association of Orthodontists.Objective: Surgically assisted maxillary protraction is an alternative protocol in severe Class III cases or after the adolescent growth spurt involving increased maxillary advancement. Correction of the maxillary deficiency has been suggested to improve pharyngeal airway dimensions. Therefore, this retrospective study aimed to analyze the airway changes cephalometrically following surgically assisted maxillary protraction with skeletal anchorage and Class III elastics. Methods: The study population consisted of 15 Class III patients treated with surgically assisted maxillary protraction combined with skeletal anchorage and Class III elastics (mean age: 12.9 ± 1.2 years). Growth changes were initially assessed for a mean of 5.5 ± 1.6 months prior to treatment. Airway and skeletal changes in the control (T0), pre-protraction (T1), post-protraction (T2), and follow-up (T3) periods were monitored and compared using lateral cephalometric radiographs. Statistical significance was set at p 0.05). No statistically significant changes were observed in the airway parameters in the follow-up period either. However, Sella to Gonion distance increased significantly (p < 0.05) during the follow-up period. Conclusions: No significant changes in pharyngeal airway parameters were found during the control, maxillary protraction, and follow-up periods. Moreover, the significant increases in the skeletal parameters during maxillary protraction were maintained in the long-term.Publication Open Access Occlusal plane rotation and orthodontic decompensation: influence on the outcome of surgical correction of class III malocclusion(2022-03-01) YILMAZ, HANİFE NURAY; ŞEKER E. D., SUNAL AKTÜRK E., YILMAZ H. N., Kucukkeles N.Purpose The aim of this retrospective multicenter study is to evaluate the influence of surgical manipulation of the upper occlusal plane (UOP) and orthodontic decompensation on the outcome of class III orthognathic surgery. Methods Incisor inclinations, occlusal plane inclination as well as skeletal and soft tissue changes were assessed in lateral cephalograms of 85 class III patients who had previously undergone orthognathic surgery. Fourteen linear and eight angular measurements were performed on each radiograph at the beginning of treatment (T0), before surgery (T1) and at the end of treatment (T2) using imaging software. After measurement of variables, Mann-Whitney U-test, repeated-measures analysis of variance (ANOVA) with Bonferroni multiple comparison test, and Spearman\"s correlation analysis were performed. Results A statistically significant improvement was observed in both sagittal skeletal and soft tissue measurements (p < 0.05). Surgical change in UOP was significantly correlated with changes in overbite, upper lip strain and soft tissue B-point change in the sagittal direction (p < 0.05). Overjet change was significantly correlated with changes in the soft tissue and all sagittal skeletal parameters except for SNA. Changes in the incisor inclinations was significantly correlated with changes in the sagittal skeletal parameters and lower facial height. Significant differences were also observed between the groups with induced clockwise or counterclockwise rotation of the mandible in terms of IMPA (long axis of LI to mandibular plane), overbite, upper lip strain and position of soft tissue B-point (p < 0.05). Conclusion Sufficient dental decompensation is crucial for controlling the sagittal as well as the vertical relationship during surgery. Counterclockwise rotation provides an increase in sagittal projection of the mandibular body at the soft tissue B-point.Publication Metadata only Postoperative evaluation of Er:YAG laser, piezosurgery, and rotary systems used for osteotomy in mandibular third-molar extractions(CHURCHILL LIVINGSTONE, 2021) YILMAZ, HANİFE NURAY; Civak, Tayfun; Ustun, Tugba; Yilmaz, Hanife Nuray; Gursoy, BaharObjective: This study compared patient postoperative pain, swelling, and trismus after usage of rotary instruments, piezosurgery, and Er:YAG lasers in mandibular third-molar extraction. Materials and methods: This prospective study was executed with class II and position B vertically impacted mandibular third molars. Patients were divided into three groups according to the osteotomy system used to remove retentive bone: rotary instruments, piezosurgery, and Er:YAG laser. Postoperative painwas evaluated using VAS questionnaires at 12 h, 24 h, 48 h, and 7 days after procedures. Trismus was evaluated by measuring the distance between the maxillary and mandibular incisors at maximum mouth opening, and comparing preoperative measurements with those for postoperative days 2 and 7. Analyses of swelling were carried out via a stereophotogrammetry system. Operation times were measured using a digital stopwatch from the initial incision to the final suture. Results: There were no statistically significant differences between the groups in terms of pain, trismus, or swelling (p > 0.05). Pain persisted more in the rotary instrument group 24 h later (0 +/- 1.3; p = 0.001). The pain scores obtained after 48 h for the piezosurgery (1.81 +/- 2.29) and rotary (2.2 +/- 2.12) groups were observed at 24 h in the laser group (2.19 +/- 1.52). The mean operation time was highest using the laser (19.1 +/- 3.85 min; p = 0.001) and lowest using rotary instruments (9.88 +/- 2.97 min; p = 0.001). Conclusion: Piezosurgery and Er:YAG laser are good alternatives to rotary instrument systems in third-molar extraction, but both systems are slower than traditional rotary instruments.

Materials and Methods: The study group consisted of 19 patients with a mean age of 13.12 +/- 1.28 years. Initially, patients were monitored for 5 months before treatment to evaluate growth changes. Changes during control, protraction and fixed orthodontic treatment periods were compared with the cephalometric radiographs taken initially, before protraction, after protraction, and after fixed orthodontic treatment. Treatment outcomes also were compared with the growth effects. Results: Sagittal measurements of maxilla showed significant improvements (3.59 +/- 1.32 mm) during the protraction period (3.85 +/- 1.12 months) whereas no significant changes were seen during the control period. Upper and lower incisor inclinations were increased, and the upper occlusal plane angle showed significant counterclockwise rotation during protraction. Significant soft-tissue changes also reflected the underlying skeletal changes. Maxillary advancement was stable during fixed orthodontic treatment. Conclusion: Compared with control period of the patients, this protocol produced significant improvements in skeletal and soft-tissue structures.Publication Metadata only Three-dimensional evaluation of surgically assisted asymmetric rapid maxillary expansion(MOSBY-ELSEVIER, 2019) UĞURLU, FAYSAL; Karabiber, Gulden; Yilmaz, Hanife Nuray; Nevzatoglu, Sirin; Ugurlu, Faysal; Akdogan, TunaIntroduction: Unilateral posterior crossbite is classified as true unilateral posterior crossbite (TUPC) or functional posterior crossbite (FPC). The differential diagnosis between TUPC and FPC is of utmost importance for the decision of expansion protocol because conventional expansion methods have some shortcomings for TUPC. The aim of this retrospective study was to 3-dimensionally evaluate the effects of asymmetric rapid maxillary expansion combined with unilateral osteotomy. Methods: This study sample comprised 16 patients (mean age 18.38 +/- 6 1.45) with TUPC. A Hyrax acrylic cap included the maxillary premolars and molars on the constricted side, and all teeth up to the central incisor were included on the other side to increase anchorage. Unilateral surgically assisted rapid maxillary expansion was performed and included anterior (aperture piriformis), lateral (zygomatic buttress), and posterior (pterygomaxillary junction) osteotomies on the constricted side and separation of the midpalatal suture. Cone-beam computed tomographic scans taken just before the operation and after 6 months of retention were used to assess skeletal, dental, and periodontal changes. Results: Expansion was seen on both sides; however, the amount of expansion and tipping was higher on the osteotomy+ side. Because the canines were not included in the acrylic cap on the osteotomy+ side, they did not present the same amount of tipping as the ipsilateral posterior teeth. More teeth were affected periodontally on the osteotomy- side; however, there were no clinically significant differences between the osteotomy+ and osteotomy+ sides (mean differences range +10.54 to -0.57 mm). The aperture piriformis width increased significantly on the osteotomy+ side. Conclusions: The treatment mechanics had no clinically detrimental effects on the supporting alveolar bone of the maxilla on either side, and it was thought to be effective in cases with TUPC; however, case selection is crucial.Publication Metadata only Do we pay for maxillary protraction? Evaluation of the effects of Alt-RAMEC protocol and face mask treatment on root development(SPRINGER HEIDELBERG) YILMAZ, HANİFE NURAY; Yilmaz, Berza Sen; Seker, Elif Dilara; Yilmaz, Hanife Nuray; Kucukkeles, NazanObjectives To evaluate root development of pediatric patients treated with Alt-RAMEC + Face mask therapy. Material and methods The 19 subjects (9 girls, 10 boys; mean age: 8.6 +/- 1.1 years) treated with Alt-RAMEC and a Petit-type face mask were included to the study. The cone-beam tomography (CBCT) records of these patients were used to quantify the root length. The root length measurements of 456 permanent teeth (maxillary-mandibular incisors, canines, premolars, and first molars) were performed at the beginning of the treatment (T0), after the Alt-RAMEC protocol (T1), and at the end of the face mask treatment (T2) using Planmeca Romexis software. Results Tooth length values increased significantly in the maxillary teeth except the central incisors, left lateral incisor, the palatal root of the right first molar, and distal and palatinal roots of the left first molar (p < 0.05). Mandibular teeth also showed significant increase in the root length except mandibular central incisors and the distal root of left first molar (p < 0.05). The change in tooth lengths from T0 to T1 showed positive delta values. The comparison of the change in tooth lengths after the Alt-RAMEC protocol and after the face mask therapy showed that increment T2-T1 was statistically significantly higher compared with increment T1-T0 (p < 0.05). Conclusions Alt-RAMEC + Face mask therapy seem not to inhibit root development of maxillary and mandibular teeth in the mixed dentition.Publication Metadata only Candida Albicans’ların Nazoalveoler şekillendirme (NAŞ) aygıtlarına yapışma sıklığı(2014-10-29) YILMAZ, HANİFE NURAY; CAN, BANU; KADİR, TANJU; NEVZATOĞLU Ş., YILMAZ H. N., CAN B., KADİR T.Publication Open Access Comparison of the effects of rapid maxillary expansion and alternate rapid maxillary expansion and constriction protocols followed by facemask therapy(KOREAN ASSOC ORTHODONTISTS, 2019) ÖNEM ÖZBİLEN, ELVAN; Ozbilen, Elvan Onem; Yilmaz, Hanife Nuray; Kucukkeles, NazanObjective: The aim of this retrospective study was to evaluate and compare the changes in the pharyngeal airway (PA), maxillary sinus volume, and skeletal parameters after rapid maxillary expansion (RME) and alternate rapid maxillary expansion and constriction (Alt-RAMEC) followed by facemask (FM) therapy. Methods: The records of 40 patients with skeletal Class lll malocclusion due to maxillary retrognathism were collected, and the patients were assigned into two groups. The first group comprised 8 male and 12 female patients (mean age, 10.0 +/- 1.1 years) treated using RME/FM for an average of 10 months. The second group comprised 10 male and 10 female patients (mean age, 9.64 +/- 1.3 years) treated using Alt-RAMEC/FM for an average of 12 months. Cone-beam computed tomography images acquired before (TO) and after treatment (T1) were evaluated. Results: Regarding the skeletal effects, significant differences between the groups were the increase in ANS-HRP (perpendicular distance of ANS to the horizontal reference plane, 0.99 mm, p <0.05) in the Alt-RAMEC/FM group and the decrease in PP-SN (palatal plane to Sella-Nasion plane, 0.93 degrees, p < 0.05) in the RME/FM group. Maxillary sinus volumes increased significantly in both the groups, and the increase was statistically significantly higher in the AltRAMEC/FM group. Although no significant intergroup differences were observed in PA volumes, both lower (1,011.19 mm(3)) and total (1,601.21 mm(3)), PA volume increased significantly in the Alt-RAMEC/FM group. Conclusions: The different expansion devices and protocols used with FM therapy do not seem to affect the forward movement of the maxilla and PA volumes. In contrast, the increase in maxillary sinus volume was greater in the Alt-RAMEC/FM protocol.Publication Metadata only Maternal and paternal anxiety levels through primary lip surgery(ELSEVIER, 2020) ABUHAN, ECE; Yilmaz, Hanife Nuray; Abuhan, EceAim: The aim of this study was to evaluate the anxiety levels of the parents of infants with cleft lip and palate (CLP) before and after primary lip surgery. Materials and method: Forty mothers (mean ages: 31.9 +/- 6.16 years) and 40 fathers (mean ages: 34.6 +/- 5.91 years) of infants with CLP were included in this study. They were asked to answer the Amsterdam Preoperative Anxiety and Information Scale (APAIS) and Spielberger's State-Trait Anxiety Inventory (STAI) just 1 h before the primary lip surgery (T0) and 1 month after (T1) surgery. Student t-test and Mann-Whitney U test were used for inter-group comparison, the paired-sample t was used for the intragroup comparisons (p < 0.05). Results: There were no statistically significant differences for the comparisons of state (STAI-S) and trait (STAI-T) anxiety or APAIS scores between the parents. While state anxiety scores of the mothers increased significantly post-surgically, APAIS scores showed significant decreases in both parents (p < 0.05). APAIS scores of the fathers with bilateral CLP infants were significantly higher (p < 0.05) than the fathers of unilateral ones. The parents with local anesthesia experience showed significantly lower APAIS scores (p < 0.05). A negative correlation was present between maternal age and STAI-T, whereas a positive correlation was present between paternal age and the anxiety. Conclusions: The anxiety levels of the parents were similar. Parents asked for more information about the anesthesia than the surgery, therefore communication with the anesthesiologist in the preoperative period is important. Routine assessment of parents' stress and psychosocial support should be provided by the cleft team. (C) 2020 Elsevier Masson SAS.

N.Objective To investigate the distribution of dental anomalies between non-syndromic orofacial cleft patients and their association with the cleft type and gender. Design Retrospective cross-sectional study involving examination of intraoral dental records and radiographs. Patients 300 non-syndromic orofacial cleft patients included (161 males and 139 females, mean age: 10.23 +/- 2.3 years). Main Outcome Measures: Variables analyzed: tooth agenesis, microdontia, and supernumerary teeth. Data analysis: Chi-square and Fisher\"s exact tests to investigate the correlation between dental anomalies, cleft type, and gender. Results Agenesis occurred in 66% of the subjects, supernumerary teeth in 19.6%, and microdontia in 18.3%. In females with unilateral left cleft lip and palate (CLP), agenesis was significantly higher compared to males. Both genders presented significant agenesis of maxillary lateral incisors and right central incisor. Significant agenesis of central incisor, canine and second premolar on the upper left side and lower second premolars were observed only in males, with significant microdontia for maxillary lateral incisors and left central incisor. Significant agenesis of maxillary first premolars was seen only in females. Agenesis in maxillary quadrants was significant for patients with unilateral right and left CLP, and bilateral CLP. In mandibular quadrants, agenesis was substantially higher for patients with isolated CP. Conclusions Results suggest that tooth agenesis and microdontia might not be directly associated with the cleft area\"s anatomical irregularity but are affected by gender and other genetic factors that regulate the development of the anomaly and the orofacial clefting mutually.
