Anterior maxillary osteotomy is a traditional operation in the treatment of maxillary protrusion. Varies fields about operation have been changed or improved in those years to avoid different kinds of complications. In our study, the authors would present 1 kind of improved anterior maxillary osteotomy surgical method. The study was conducted at the Department of Oral and Maxillofacial Surgery, Guanghua School of Stomatology, Hospital of Stomatology, Guangzhou, Guangdong province. Patients are divided into improved group and general group. Patients after surgery were claimed to have regular return visits. Occlusion, tooth vitalities, postoperative complications would be well evaluated. The operative time, blood losses, complications showed no different at maxillary operation. Our procedure could give much better and direct sight of anterior maxillary bone, and the simplified osteotomy lines could help maxilla move, reduce the times spent on hard tissue cut off or grind. The modified procedure can meet clinical command, improve dentofacial deformities, and gives convenience to surgeon.

Objective: Miniscrews are commonly utilized as temporary anchorage devices (TADs) in cases of maxillary protrusion and premolar extraction. This study aimed to investigate the effects and potential side effects of two conventional miniscrew configurations on the maxillary incisors.
Methods: Eighty-two adult patients with maxillary dentoalveolar protrusion who had undergone bilateral first premolar extraction were retrospectively divided into three groups: non-TAD, two posterior miniscrews only (P-TADs), and two anterior and two posterior miniscrews combined (AP-TADs).
Evaluation of the Changes in the Alveolar Bone and Root Length after Maxillary Anterior Tooth Retraction and the Factors Influencing Them.

Introduction: There is a scarcity of studies in which both alveolar bone remodeling and root resorption are simultaneously assessed and compared against possible influencing factors such as rate of retraction and change in inclination. The aim of our study was to assess the changes in the alveolar bone thickness and root length of the maxillary anterior teeth after retraction and correlate it to the potential influencing factors, namely rate of retraction and change in inclination.
Subjects And Methods: Ten patients requiring upper premolar extraction as part of their treatment were included in the study.

Objective: This longitudinal clinical study monitored annually the maxillary and mandibular bone remodeling and masticatory function in complete denture (CD) wearers rehabilitated with implant-retained mandibular overdentures (MO) over three years and combined radiographic and masticatory function data to assess the correlation between bone remodeling and masticatory function.
Design: Thirty-nine MO wearers were monitored annually to assess changes in: i) residual ridge in the anterior and posterior maxillary region; ii) posterior height and posterior area index (PAI) in the mandible; and iii) masticatory function. Bone remodeling was measured through linear and angular measurements using panoramic radiographs.

Objectives: This study aimed to investigate the clinical characteristics of deciduous fused teeth and their inherited permanent-tooth performance type by using panoramic radiographs.
Methods: A total of 14 404 panoramic radiographs of 3- to 6-year-old children with deciduous dentition were collected from January 2023 to July 2024. The incidence of deciduous fused teeth was observed, and the abnormality of permanent teeth was recorded.
