Effects of modified and conventional facemask therapies with expansion on dynamic measurement of natural head position in Class III patients

TANCAN UYSAL

Introduction: The aim of this prospective clinical trial was to assess the effects of varying force directions on the dynamic measurement of natural head position and orofacial airway dimensions of Class III patients during maxillary orthopedic protraction compared with an untreated control group. Methods: The conventional facemask group comprised 15 patients (8 girls, 7 boys; mean age, 9.6 6 1.3 years), the modified facemask group comprised 15 patients (7 girls, 8 boys; mean age, 9.5 6 1.5 years), and the control group comprised 15 subjects (7 girls, 8 boys; mean age, 9.8 6 1.6 years).

Ethnic differences in dentofacial relationships of Turkish and Saudi young adults with normal occlusions and well-balanced faces

TANCAN UYSAL

Objectives: The aims of the present study were (1) to determine ethnic differences in craniofacial dimensions between Turkish and Saudi populations and (2) to identify possible gender differences between males and females, based on a sample of untreated young adult subjects with normal occlusions and well-balanced faces. Methods: In total, 163 cephalometric radiographs were traced and evaluated to compare untreated adults of Turkish and Saudi ethnicity. The Turkish group comprised 86 subjects; 45 females and 41 males. The Saudi group comprised 77 subjects; 39 females and 38 males. For st ...Daha fazlası

Comparison of craniofacial morphology, head posture and hyoid bone position with different breathing patterns

TANCAN UYSAL

Objectives: The aim of this study was to evaluate differences in craniofacial morphology, head posture and hyoid bone position between mouth breathing (MB) and nasal breathing (NB) patients. Methods: Mouth breathing patients comprised 34 skeletal Class I subjects with a mean age of 12.8 ± 1.5 years (range: 12.0–15.2 years). Thirty-two subjects with skeletal Class I relationship were included in the NB group (mean 13.5 ±1.3 years; range: 12.2–14.8 years). Twenty-seven measurements (15 angular and 12 linear) were used for the craniofacial analysis. Additionally, 12 measurements were evalu ...Daha fazlası

Low-shrinking composites. Are they reliable for bonding orthodontic retainers?

TANCAN UYSAL

To evaluate the shear bond strength (SBS), fracture mode, wire pull out (WPO) resistance and microleakage between low-shrinking and conventional composites used as a lingual retainer adhesive. Methods: A total of 120 human mandibular incisor teeth, extracted for periodontal reasons, were collected. Sixty of them were separated into two groups. To determine the SBS, either Transbond-LR (3M-Unitek) or Silorane (3M-Espe) was applied to the lingual surface of the teeth by packing the material into standard cylindrical plastic matrices (Ultradent) to simulate the lingual retainer bonding area. To t ...Daha fazlası

OPG and RANKL levels around miniscrew implants during orthodontic tooth movement

İLKNUR VELİ | ŞÜKRÜ ENHOŞ

Introduction: The aim of this study was to determine the peri-miniscrew implant crevicular fluid receptor activator of nuclear factor-lB ligand (RANKL) and osteoprotegerin (OPG) levels around loaded and unloaded miniscrew implants at different time intervals. Methods: Twenty loaded and 16 unloaded miniscrew implants were included in this study. All miniscrew implants were placed bilaterally between the maxillary second premolars and first molars as anchorage units for canine distalization. Peri-miniscrew implant crevicular fluid was taken from the mesiobuccal aspects of the loaded and unl ...Daha fazlası
