Appraisal of the relationship between tooth inclination, dehiscence, fenestration, and sagittal skeletal pattern with cone beam computed tomography
(2019) Coskun, Ipek; Kaya, Burcak; 30741575
Objectives: To examine the relationship between sagittal facial pattern and dehiscence/fenestration presence in conjunction with buccolingual tooth inclination by using cone beam computed tomography. Materials and Methods: The study was carried out on the cone beam computed tomography scans of the following three groups of patients (n = 20 in each group): Class I, Class II, Class III. Buccolingual tooth inclination, buccal dehiscence/fenestration presence, and lingual dehiscence/fenestration presence were evaluated on each tooth. Analysis of variance, Kruskall-Wallis H, Scheffe, and chi-square tests were used for statistical comparisons. Results: Differences (P<.05) were observed between the groups for inclination of upper incisors and all lower teeth except for second molars. Dehiscence prevalence in the upper buccal and posterior buccal regions was higher (P<.05) in the Class I group when compared with the other groups. Lower buccal and anterior buccal regions showed higher (P=.0001) dehiscence prevalence in all groups. No difference was observed in fenestration prevalence between the groups. The upper buccal and anterior buccal regions showed higher (P=.0001) fenestration prevalence in all groups. Conclusions: Orthodontists must consider concealed alveolar defects in treatment planning to avoid gingival recession or tooth mobility.
Comparative evaluation of periodontal effects and survival rates of Memotain and five-stranded bonded retainers A prospective short-term study
(2020) Kartal, Yasemin; Kaya, Burcak; Polat-Ozsoy, Omur; 32780168
Purpose To prospectively compare the short-term periodontal effects and survival rates of mandibular lingual canine-to-canine Memotain (CA-Digital, Mettmann, Germany) and five-stranded bonded retainers. Methods In all, 52 patients requiring retention after orthodontic treatment were assigned to 2 study groups (n = 26 in each group). Retention was provided by Memotain retainers which were fabricated digitally using CAD-CAM (computer-aided design and computer-aided manufacturing) technology in the first group and by five-stranded retainers which were fabricated manually using a conventional bending method in the second group. The patients were examined at the following time points: 1 week, 1 month, 3 months and 6 months. Plaque index, gingival index, probing depth, marginal recession, bleeding on probing, failure rate per tooth, and survival rate of retainer wires were analyzed by Mann-Whitney U, Friedman, Wilcoxon signed-rank, and chi(2) tests. Results The differences between the groups were nonsignificant for plaque index, gingival index, probing depth, marginal recession, bleeding on probing, failure rate per tooth and survival rate of retainer wires. Significant differences were observed within the groups throughout the follow-up period for plaque index and probing depth. The survival rates of retainer wires were 77% for the Memotain retainers and 73% for the five-stranded retainers for the 6-month follow-up period. Conclusions Periodontal outcomes and survival rates of Memotain and five-stranded mandibular lingual bonded retainers were similar. Furthermore, periodontal health was maintained and considerably high survival rates were achieved with both retainer types.
Cone Beam Computed Tomography in Orthodontics
(2018) Kaya, Burcak; Coskun, Ipek; 30112468
Orthodontists treat malocclusions by applying three-dimensional forces. For years, the diagnosis of this three-dimensional condition and the related treatment plan has been based on two-dimensional imaging. Lateral and anteroposterior cephalometric, panoramic, and periapical radiographs are some of the two-dimensional radiographs routinely used in orthodontics. Despite being highly beneficial in evaluating skeletal and dental relations, these radiographs fail to provide sufficient two-dimensional information in certain cases. The purpose of this compilation is to review the use of cone-beam computed tomography in orthodontics.

Effect of maxillary incisors, lower lip, and gingival display relationship on smile attractiveness
(2020) Tosun, Hande; Kaya, Burcak; 32115112
Introduction: This study aimed to evaluate the effect of the relationship between maxillary incisors and lower lip in conjunction with the maxillary gingival display on perception of smile attractiveness. Methods: The frontal intraoral photograph of ideally aligned teeth was modified using image processing software. Twenty different smiles were obtained with a combination of 10 different maxillary incisor edge-lower lip distances and 10 different maxillary gingival display amounts. Attractiveness of these 20 smiles was evaluated by orthodontists (n = 101), dentists (n = 107), and laypersons (n = 105). Two-way ANOVA was used to compare alterations on smile esthetics, and repeated measures ANOVA was used to evaluate the interaction between the variables. Bonferroni-adjusted pairwise comparisons were applied for determining the differences between the rater groups. Results: Maxillary incisor edge-lower lip distance (P < 0.01), maxillary gingival display amount (P < 0.001), and rater group (P < 0.01) had statistically significant influences on perception of smile attractiveness. Orthodontists prefer to see a minimal amount of mandibular incisor exposure and almost full crowns of maxillary central incisors. Dentists and laypersons are more tolerant of mandibular incisor exposure and maxillary central incisor coverage by the upper lip. None of the rater groups preferred the coverage of maxillary incisor edges or maxillary gingival display. Conclusions: Elimination of maxillary gingival display helps to improve smile attractiveness, whereas the coverage of maxillary incisor edges has a negative influence.
Factors That May Increase The Risk of External Apical Root Resorption During Orthodontic Treatment Retrospective Clinical Investigation
(2024) Kaya, Burcak; Gulsahi, Ayse; Turkyilmaz, Gizem
PurposeTo determine the correlation between external apical root resorption and malocclusion-related variables in patients treated with fixed orthodontic appliances.MethodsIn all, 103 patients aged 12-15 years and treated with edge-wise appliances either without extractions or with four premolar extractions were included in this retrospective cohort study. External apical root resorption was assessed in the pre- and posttreatment panoramic radiographs of these patients for incisors, canines, premolars, and first molars. A total of 2332 teeth were evaluated in 206 panoramic radiographs obtained from 103 patients. The gender of the patients, duration of orthodontic treatments, presence of premolar extractions, Angle classification, overbite, overjet and amount of crowding were assessed. Wilcoxon signed-rank test, Mann-Whitney U test, and Kruskal-Wallis test were used for statistical analysis of the data.ResultsStatistically significant (p < 0.001) root resorption occurred in all examined teeth during orthodontic treatment. The degree of root resorption observed in the premolars was significantly greater in premolar extraction cases than in nonextraction cases. Statistically significant negative correlations were found between the degree of root resorption of the maxillary lateral teeth and between the maxillary first premolar teeth and the amount of maxillary crowding.ConclusionsThe orthodontic treatment protocols and the amount of tooth movements achieved were shown to be dependent on the severity of dental malocclusions and they have an influence on the amount of external apical root resorption that occurs during the course of orthodontic treatment.
Fixed Orthodontic Retainers: A Review
(2019) Kartal, Yasemin; Kaya, Burcak; 31294414
Orthodontic retention is defined as maintaining teeth in optimal aesthetic and functional position after treatment. Despite the necessity of retention phase and the factors influencing the stability of the teeth after orthodontic treatment was discussed by the orthodontist for a long time, it is accepted that a retention phase is essential for stability of orthodontic treatment results nowadays. Therefore, the application of a suitable retention method is important both for prevention of relapse after orthodontic treatment and for increasing patient satisfaction. Removable appliances had been used for many years for retention purposes. Later, fixed retainers were introduced to prevent relapse as having a number of advantages, such as better aesthetics, no need for patient cooperation, effectiveness, and suitability for lifelong retention. However, their need for precise bonding technique, fragility, and tendency to cause periodontal problems by weakening oral hygiene are some of their disadvantages.
Multidisciplinary management of an adult skeletal Class III patient with generalized aggressive periodontitis and canine-premolar transposition
(2021) Ince Bingol, Sinem; Nisanci Yilmaz, Mediha Nur; Kaya, Burcak
This case report presents orthodontic camouflage treatment and the correction of transposed canine-first premolar teeth in a patient who presented with a skeletal Class III and familial periodontal problem. A 28-year-old female patient who was diagnosed with generalised aggressive periodontitis was treated by scaling and root planing plus the adjunctive use of systemic antibiotics and surgical therapy prior to referral to the orthodontic department. After the progression of the disease was controlled, orthodontic treatment was commenced to correct the dental transposition by using a modified Nance-TPA appliance and sectional arch mechanics. A non-extraction orthodontic camouflage treatment was planned to eliminate the anterior crossbite and to establish a proper occlusion by closing the multiple diastemata. Treatment outcomes remained stable in the 2-year follow-up period. Severe orthodontic-periodontal problems can be successfully treated by oral hygiene motivation, an interdisciplinary approach, and the selection of appropriate biomechanics.
Periodontal effects and survival rates of different mandibular retainers: comparison of bonding technique and wire thickness
(2019) Gokce, Begum; Kaya, Burcak; 31365926
Objectives: This non-randomized prospective cohort study aimed to compare the periodontal effects and success rates of mandibular canine-to-canine fixed retainers having different bonding techniques and wire thicknesses. Materials and methods: Hundred patients requiring retention after orthodontic treatment were assigned to five study groups (n = 20 in each group, 61 females/39 males, median age range 16.5-18.0 years). Retention was provided by 0.0215"/direct, 0.0215"/indirect, 0.0175"/direct, 0.0175"/indirect bonded multistranded wires and removable Essix appliances. The primary and secondary outcomes were periodontal effects and success rates. The patients were examined in 1 week, 1 month, 3 months and 6 months follow-up appointments. Plaque index, gingival index, probing depth, marginal recession, bleeding on probing, failure rate per retainer wire and survival of retainer wires were analysed by Kruskal-Wallis H, Mann-Whitney U and chi-square tests. Results: Significant differences were observed between the fixed retainer (FR) and Essix (E) groups in gingival index scores at 1 month [mean FR: 1.13 (95% confidence interval (CI): 0.81-1.44), mean E: 0.40 (95% CI: 0.14-0.69), mean difference: 0.73, P < 0.01], 3 months [mean FR: 0.97/1.01 (95% CI: 0.65-1.30/0.72-1.30), mean E: 0.52 (95% CI: 0.25-0.82), mean differences: 0.45/0.49, P < 0.05], 6 months [mean FR: 0.94 (95% CI: 0.62-1.27), mean E: 0.35 (95% CI: 0.15-0.58), mean difference: 0.59, P < 0.05] and in bleeding on probing scores at 1 month [mean FR: 3.05 (95% CI: 2.12-3.98), mean E: 1.15 (95% CI: 0.42-1.88), mean difference: 1.90, P < 0.01]. The survival rates of retainer wires were 85 per cent for the 0.0215" direct/indirect and 90 per cent for the 0.0175" direct/indirect groups for the 6 months follow-up. Limitations: Six months follow-up period, which demonstrates only short-term outcomes. Conclusions: The periodontal outcomes or survival rates of mandibular fixed retainers were not affected by bonding technique or wire thickness, whereas gingival health improved with Essix retainers but not with fixed retainers.
Pharyngeal airway and hyoid bone position changes of skeletal anchored Forsus Fatigue Resistant Device and activator appliances
(2021) Ince-Bingol, Sinem; Kaya, Burcak; https://orcid.org/0000-0002-7014-0784; 33449194
Objectives To evaluate the effects of miniplate anchored Forsus Fatigue Resistant Device (MAF) and activator treatments in the pharyngeal airway dimensions and hyoid bone position. Materials and methods Thirty-eight patients with mandibular retrusion who were treated with either MAF or activator were selected retrospectively and compared with an untreated control group. The data of 114 lateral cephalograms, comprising those taken before treatment (T1) and at the end of functional treatment (T2), were evaluated with regard to their linear, angular, and area measurements. Results The mandibular length increased and the hyoid bone moved forward with both treatments (P < 0.05). The horizontal change in the hyoid bone position with MAF treatment was correlated with changes in the point B and ANB angle. Increases of 1.8 mm, 1.4 mm, and 1.8 mm in the pharyngeal airway dimensions were obtained at the levels of the second, third, and fourth cervical vertebra, respectively, with the MAF treatment. On the other hand, an increase of 1.9 mm was found at the level of the fourth cervical vertebra with the activator treatment. The greatest vertical movement in the Menton and the highest increase in the oropharyngeal area were observed in the MAF group (P < 0.05). Conclusion Both the MAF and activator treatments caused favorable maxillomandibular changes; however, the MAF treatment provided a greater increase in the oropharyngeal area according to both the increase in mandibular length and the change in the vertical position of the mandible. Clinical relevance Functional appliances were found to be useful in increasing the pharyngeal airway dimensions in the shortterm. The skeletal anchored fixed functional appliance caused a greater increase in the oropharyngeal airway area that may be beneficial for Class II patients who carry a risk of having respiratory problems.
Relationship between alveolar bone thickness, tooth root morphology, and sagittal skeletal pattern: A cone beam computed tomography study
(2019) Coskun, Ipek; Kaya, Burcak; 30980091
PurposeThe goal of this work was to examine the relationship between sagittal facial pattern and thickness of alveolar bone in conjunction with root morphology of teeth by using cone beam computed tomography (CBCT).MethodsThe study was carried out on the CBCT scans from 3group of patients (n=20 in each group). The first group involved skeletal class1, the second group involved skeletal class2, and the third group involved skeletal class3 patients. In all, 14permanent teeth and interdental regions in the maxilla and mandible were evaluated. Root length and root width were measured on each tooth. Buccal cortical bone thickness, cancellous bone thickness, and lingual cortical bone thicknesses were measured in each interdental region. Analysis of variance, Kruskall-WallisH and Mann-WhitneyU tests were used for statistical comparisons.ResultsNo significant difference was found between the groups for root length, root width, buccal cortical bone and lingual cortical bone thickness. A significant difference was observed between the groups for cancellous bone thickness as it was thicker in skeletal class2 group. Cortical bone was thicker in the mandible compared to maxilla on both buccal and lingual sides and it was thicker in the posterior region compared to the anterior region on the buccal side.ConclusionsDifferences in cancellous bone thickness between different sagittal facial patterns and differences in cortical bone thickness between different alveolar regions should be taken into consideration when planning orthodontic tooth movements and anchorage mechanics..

(2019) Cubuk, Secil; Kaya, Burcak; Sahinoglu, Zahire; Ates, Ufuk; Ozcirpici, Ayca Arman; Uckan, Sina; 30413832
ObjectivesAim of this study is to evaluate success rates and complications related with symphyseal miniplate anchorage systems used for treatment of Class2 and Class3 deformities.MethodsAtotal of 58miniplates applied to 29growing patients were evaluated. The first group comprised 24symphyseal miniplates applied to 12patients and Forsus Fatigue Resistant Devices were attached to the head of the miniplates for mandibular advancement. The second group consisted of 34symphyseal miniplates applied to 17patients and intermaxillary elastics were applied between acrylic appliances placed on the maxillary dental arch and the symphyseal miniplates for maxillary protraction. Success rate and complications of the symphyseal plate-screw anchorage system were evaluated.ResultsThe overall success rate of symphseal miniplates was 87.9%. Six miniplates showed severe mobility and 2miniplates broke during orthodontic treatment. Infection, miniplate mobility and mucosal hypertrophy were statistically different between the two groups.ConclusionsSymphyseal miniplates were generally used as successful anchorage units in most patients. Infection, mobility, and mucosal hypertrophy occurred more frequently in Class2 deformity correction. However, the success rates regarding the two treatment modalities were comparable. ZusammenfassungZieleZiel der vorliegenden Studie ist es, Erfolgsraten und Komplikationen im Zusammenhang mit symphysealen Miniplattenverankerungssystemen zur Behandlung von Klasse-II- und -III-Anomalien zu bewerten.MethodenAusgewertet wurden insgesamt 58Miniplatten, die bei 29Patienten im Wachstum inseriert wurden. In der ersten Gruppe wurden 24symphyseale Miniplatten bei 12Patienten inseriert. Zur Korrektur der Unterkieferrucklage wurden Forsus-Apparaturen an den Miniplatten verankert. In der zweiten Gruppe wurden 34symphyseale Miniplatten bei 17Patienten inseriert. Zur Protraktion des Oberkiefers wurden intermaxillare Elastics verwendet, die zwischen Acrylgeraten im Oberkiefer und den symphysealen Miniplatten eingehangt wurden. Untersucht wurden Erfolgs- und Komplikationsraten des symphysealen Platten-Schrauben-Verankerungssystems.ErgebnisseDie Gesamterfolgsrate der symphsealen Miniplatten betrug 87,9%. Bei 6Miniplatten zeigte sich eine hohe Mobilitat, 2frakturierten wahrend der kieferorthopadischen Behandlung. Das Auftreten von Infektion, Miniplattenmobilitat und Schleimhauthypertrophie war zwischen den beiden Gruppen statistisch unterschiedlich.SchlussfolgerungenSymphyseale Miniplatten wurden in der Regel bei den meisten Patienten als erfolgreiche Verankerungseinheiten eingesetzt. Infektion, Mobilitat und Schleimhauthypertrophie traten haufiger bei Klasse-2-Korrekturen auf, die Ergebnisse beider Behandlungsmethoden unterschieden sich jedoch nur geringfugig.
The Impact Of Dentofacial Characteristics And Malocclusions On Dissatisfaction With Dentofacial Appearance
(CLINICAL ORAL INVESTIGATIONS, 2024-11-28) Ince-Bingol, Sinem; Kaya, Burcak
ObjectivesTo assess how, and to what extent, dentofacial features and malocclusions affect the perceived dissatisfaction with the appearance of dentofacial region in different age groups.Materials and methodsDissatisfaction with dental appearance (DDA) and facial appearance (DFA) of 430 patients were assessed using self-reported 5-point Likert scores (1: very satisfied - 5:very dissatisfied). Number of decayed, filled, and missing teeth, oral hygiene status, crowding in the upper/lower arches, molar relationship, overjet, overbite, posterior-crossbite, upper/lower midline deviations, face type, profile, nasal tip and chin deviations were assessed by an experienced orthodontist. Ordinal logistic regression analysis was performed to determine how the examined variables affected DDA and DFA scores.ResultsThe median age of the 430 patients (271 female, 159 male) was 23.0 years. 60.9% of the patients had Angle Class I, 32.3% had Angle Class II, and 6.7% had Angle Class III molar relationship. According to the IOTN (DC), 37.4% of the patients had grade 4 and grade 5. Gender had no impact on DDA and DFA. Being young (teenagers OR = 4.78, CI:2.43-9.40, young adults (OR = 3.15, CI: 1.70-5.83), having poor oral hygiene (OR = 2.32, CI: 1.37-3.92), missing teeth (OR = 1.19, CI:1.10-1.29), convex profile (OR = 1.94, CI:1.03-3.67), diastema (OR = 3.18, CI:1.33-7.61), crowding in the upper arch (moderate: OR = 2.10, CI:1.30-3.68, severe: OR = 5.94, CI:3.15-11.19) affected the DDA scores negatively. Class III malocclusion (OR = 5.60, CI:1.85-16.91), decreased overbite (OR = 2.44, CI:1.21-4.89), and increase in DDA scores (OR = 1.88, CI: 1.50-2.35) all increased the DFA scores.ConclusionCertain dentofacial characteristics and age of the patients significantly affect self-reported dissatisfaction with dental and facial appearance levels, with varying degrees of severity.Clinical relevanceAwareness of the impacts of malocclusions and dentofacial features that result in patient dissatisfaction among those who apply for dental treatment at the clinic enables a deeper understanding of the patient's priorities, expectations from orthodontic treatment, and satisfaction with the outcome.

(2020) Ince-Bingol, Sinem; Kaya, Burcak; Bayram, Burak; Arman-Ozcirpici, Ayca; 0000-0002-7014-0784; 32671559
Objectives The aim of the study was to investigate the treatment efficiency of miniplate anchored Forsus Fatigue Resistant Device (MAF) as compared with the activator appliance. Materials and methods Mandibular retrognathia was treated with two methods, the MAF group (8 girls, 11 boys, mean age 13.03 +/- 0.69 years) and the activator group (7 girls, 12 boys, mean age 12.68 +/- 0.73 years). An untreated control group (9 girls, 10 boys, mean age 12.95 +/- 0.73 years) was constructed to eliminate growth-related changes through the American Association of Orthodontists Foundation Legacy Collection. Data of 114 lateral cephalograms were analyzed. Results The inhibition of the maxillary growth was greater in the MAF group, whereas forward displacement of the mandible was higher in the activator group (P < 0.05). Sagittal maxillomandibular relation was improved similarly in both treatment groups (P < 0.05). Mandibular length was increased in both treatment groups with the highest increase in the activator group (P < 0.05). Retroclination of the incisors was observed in the MAF group (P < 0.05). The upper lip was retruded in the MAF group and lower lip was protruded in the activator group (P < 0.05). Conclusion The activator created greater mandibular changes, whereas the MAF provides somewhat smaller mandibular changes due to the restriction caused by retroclined maxillary incisors
