    Corticotomy-assisted maxillary protraction with skeletal anchorage and Class III elastics
    (E H ANGLE EDUCATION RESEARCH FOUNDATION, INC, 2015-01) GARİP, HASAN; Yilmaz, Hanife Nuray; Garip, Hasan; Satilmis, Tulin; Kucukkeles, Nazan
    Objective: To analyze the treatment effects of corticotomy-assisted maxillary protraction with skeletal anchorage and Class III elastics in patients with Class III malocclusions. 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.

    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, Nazan
    Objective: 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.
