    Non-Surgical Treatment of a Class III Malocclusion Using Buccal Shelf Miniscrews
    (2023) Ersay, Sevgi; Meriç, Pamir
    Class III malocclusions can be treated with orthopedic, camouflage, or orthognathic surgical methods, depending on the severity of the problem. This case report describes the non-surgical correction of a Class III problem using a buccal shelf miniscrew. In a 15-year-old female patient, bilateral 2x12 mm stainless steel screws were inserted into the mandible to distalize the lower teeth. A power chain from miniscrews was applied to the lower teeth, and the anterior crossbite was corrected 3 months later. In addition, improvement was observed in the soft tissue profile of the patient. After 13 months of treatment, the patient achieved an aesthetic and functional occlusion. The buccal shelf miniscrew-supported mandibular arch distalization treatment applied in “borderline” Class III malocclusion cases offers a successful alternative because it eliminates the side effects seen in other camouflage treatment options.

    Retention in Orthodontics: A review
    (2022) Yurdakul, Melis Seki; Meriç, Pamir
    Skeletal and dental correction obtained by orthodontic treatment may tend to return to the pre-treatment state. This condition is defined as relapse. The retention phase applied after treatment is important to obtain stable results. Periodontium, soft tissue pressures, growth and occlusion are among the factors affecting stability. In the last decade, interest in retention procedures has increased and it has been found that retention regimes differ from country to country. Although retention affects nearly every patient, there is minimal agreement on the most appropriate approach to be taken in an individual case. The many variations of the retention procedure, the introduction of different materials for retention, or individual patient factors are among the reasons that lead to difficulties in selecting retention protocols. Basic retention protocol is provided with removable and fixed retention appliances. For removable retention, hawley, wraparound, vacuum formed retention appliance and positioners are used. For fixed retention, rigid steel retention wire bonded to terminal teeth or flexible retention wires bonded to all teeth between 3-3 can be preferred. NiTi retention wires produced with CAD / CAM technology are also among the current materials. While fixed retention appliances do not require patient cooperation, periodontal follow-up is recommended. Patient cooperation is needed for the use of removable retention appliances, but easy cleaning of removable appliances is an advantage. ‘Adjunct’ procedures may also be applied to the teeth or surrounding periodontium to assist the retention process. For example, it involves reshaping teeth such as interproximal reduction or circumferential supracrestal fiberotomy. In this review, information about retention is discussed in the light of current literature.

    Thesis Trends in Postgraduate Orthodontic Education in Turkey Between 2017-2021: A Pilot Study
    (2022) Meriç, Pamir; Kılınç, Delal Dara
    Introduction: The aim of this study was to examine the theses made in orthodontic postgraduate education and to analyze the trends in terms of selected topics. Methods: Doctoral (PhD), master's (MSc) and specialization theses completed between 2017- 2021 in the field of orthodontics in Turkey were examined. Turkish National Thesis Center database was searched online. Theses completed at both public and private universities were included in the study. Results: A total of 563 theses were analyzed. 24 (4.2%) of the theses were master's, 125 (22.2%) doctorate and 424 (73.6%) specialization thesis. 173 (30.7%) of the thesis were reports the treatment outcome, 170 (30.2%) were diagnostic, 147 (26.1%) were material studies, 27 (4.8%) of theses were on finite element analysis, 22 (3.9%) were on animal experiment and 5 (0.9%) were about education. According to the methodology, it was found that 235 (41.7%) of theses were based on clinical studies, 121 (21.5%) were laboratory studies, 126 (22.4%) were measurement studies (models, films, photographs etc), 45 (8%) were questionnaires and 33 (5.9%) were computer-based studies. Discussion and Conclusion: Due to the widespread use of 3- D imaging methods, most of the theses were made using these technologies. Deep bite, artificial intelligence, vibration therapy, lingual orthodontics and aligners were the least studied subjects.
