    Clinical Effectiveness Of Buccally And Palatally Anchored Maxillary Molar Distalization: The Miniscrew-Supported 3-Dimensional Maxillary Bimetric Distalizing Arch Vs The Beneslider
    (2022) Tuncer, Nilufer Irem; Arman-Ozcirpici, Ayca; 36457217
    Introduction: This study aimed to investigate the dentoalveolar and skeletal changes achieved with a novel miniscrew-supported 3-dimensional maxillary bimetric distalizing arch (3D-MBDA) and the Beneslider. In addition, the study aimed to compare these changes between each other and with an untreated control group. Methods: Sixty-five patients with bilateral Class II molar relationship and fully-erupted maxillary second molars were included in the study. Of these patients, 23 received the miniscrew-supported 3D-MBDA (group 1), 21 received the Beneslider (group 2), and 21 served as untreated control subjects (group 3). Lateral cephalometric films and dental casts, taken at the beginning and the end of maxillary molar distalization, were analyzed to study the differences between the groups. Results: The crown distalization of the first molars was similar between the treatment groups (group 1, 3.1 mm; group 2, 3.3 mm); however, root distalization was significantly more in group 1 (5 mm) when compared with group 2 (1.7 mm). The first molars tipped 6.2 degrees in the mesial direction in group 1 and 8.2 degrees in the distal direction in group 2. The mesiobuccal cusp tip of the first molars extruded for 1.2 mm and increased vertical dimensions in group 2, whereas it intruded for 1.7 mm in group 1. Meanwhile, aforementioned parameters presented insignificant changes throughout the observation period in the control group. Inter-first molar width increased significantly in group 2 (2.7 mm). Distalization time was similar between the groups (group 1, 14 months; group 2, 15 months). The distalization rate was higher in group 2 (0.27 mm/mo) than in group 1 (0.23 mm/mo) measured from the crowns; however, it was similar between the groups (group 1, 0.25 mm/mo; group 2, 0.19 mm/mo) when measured from the trifurcation point. Conclusions: The miniscrew-supported 3D-MBDA was more effective in distalizing molar roots and maintaining vertical parameters and dental arch width while tipping the molars mesially. In contrast, the Beneslider distalized molar crowns faster, resulting in significant distal tipping. (Am J Orthod Dentofacial Orthop 2022;162:e337-e348)

    Treatment efficiency of activator and skeletal anchored Forsus Fatigue Resistant Device appliances
    (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

    Treatment of an adult skeletal class II patient with a modified surgery-first approac
    (2020) Ince-Bingol, Sinem; Arman-Ozcirpici, Ayca; 32354667
    This case report presents an 18-year-old female patient who had skeletal Class II relationship due to a mandibular retrognathia, decreased lower anterior facial height and proclined incisors with increased overjet and overbite. Her main complaints were protruding upper incisors and decreased distance between the tip of the nose and chin. A modified surgery-first approach was performed with two months of presurgical orthodontics to achieve 8 mm mandibular advancement. The total treatment time was 11 months. Improved aesthetics, a balanced facial profile and a stable and functional occlusion were obtained in less treatment time due to accelerated tooth movement.
