Advances in orthodontic treatment, particularly with the use of temporary anchorage devices (TADs), have significantly improved outcomes for adult patients with skeletal Class II malocclusion. Traditionally reliant on orthognathic surgery, these malocclusions can now benefit from non-surgical options like maxillary molar distalization. Bone screws offer superior anchorage compared to conventional methods, enabling precise tooth movement without undesirable side effects. This case report explores the efficacy of TAD-assisted maxillary molar distalization in an adult patient while focusing on a 50-year-old female who sought orthodontic treatment for Class II malocclusion, characterized by deep bite and increased overjet. Treatment involved the use of an infra-zygomatic crest (IZC) bone screw for maxillary molar distalization as a camouflage strategy to achieve optimal dento-skeletal and soft tissue profile improvements. The case also discusses the key considerations and benefits of utilizing bone screws in adult orthodontic treatment, particularly in minimizing reciprocal effects and reducing dependence on patient compliance.

Introduction: This study evaluated the dentoskeletal effects of miniscrew-anchored maxillary protraction, which included a mandibular anchorage bar and a night facemask in adolescents.
Methods: A total of 20 growing patients with Class III malocclusion and maxillary deficiency were treated with a hybrid hyrax expander with 2 miniscrews in the maxilla and a mandibular anchor bar supported in 2 miniscrews in the anterior region of the mandible. Class III elastics were used from the maxillary first molars to the mandibular anchorage bar, joining the mandibular miniscrews installed between permanent incisors and canines.

Objectives: The purpose of this retrospective study was to compare the dento-skeletal changes observed in growing Class III patients treated with the Face Mask Protocol (FMP) with and without Bite Block (BB).
Materials: Thirty subjects (12 f, 18 m) who underwent FM/BB therapy were compared to a matched group (FM) of 29 patients (15 f, 14 m) treated without BB. All patients were evaluated before treatment (T0), at the end of active treatment (T1), and at a post-pubertal follow-up observation (T2).
The orthodontic management of patients with Class III malocclusion poses numerous treatment challenges. Various removable, fixed, orthopedic, and myofunctional appliances have been recommended for its correction. The Reverse Twin Block is a removable appliance which has been used for the early management of such cases.

Background: The maxillary sinus, which is crucial for craniofacial growth, is the largest and earliest sinus to develop among the paranasal sinuses. Our study aimed to evaluate the maxillary sinus volume (MSV) in individuals with different sagittal skeletal patterns via cone beam computed tomography (CBCT).
Materials And Methods: In this study, CBCT images of 106 retrospectively selected patients (62 females and 42 males) were included.

Objective: To assess whether there is any difference in the genetic association between Class II division 1 (div. 1) and division 2 (div. 2) malocclusions using PAX9 (rs8004560) gene single nucleotide polymorphism (SNP).
