Relationship Between Laterality of Orthodontic Miniscrew Failure and Clinical Variables.

: Many reports on orthodontic miniscrew insertion focus on insertion conditions, such as technique, but not on the insertion environment, such as the operator's dominant hand. This study aimed to ascertain whether the operator's dominant hand affects laterality in the success rate of manual and motorized miniscrew insertion methods. : This study retrospectively investigated the medical records of 250 Japanese patients, aged ≥15 years, who underwent miniscrew implantation in the maxilla by right-handed operators with at least 3 years of experience.

Effects of Occlusal Contact on Maxillary Alveolar Bone Morphology in Patients with and without Anterior Open Bite: A Cross-Sectional Study.

Anterior open bite (AOB) is characterized by the absence of occlusal contact between the maxillary and mandibular anterior teeth, while the posterior teeth are in contact when occluded. Here, we aimed to clarify the difference in maxillary alveolar bone morphology in adult patients with and without AOB. This cross-sectional study was conducted on 50 adults aged 18-39 years: 25 patients without AOB (control group; 13 males and 12 females; age: mean ± standard deviation [SD], 22.
