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.
Impact of Implant Mesiodistal Distance on Peri-Implant Bone Loss: A Cross-Sectional Retrospective Study.

Department of Periodontics and Oral Medicine, The University of Michigan School of Dentistry, Ann Arbor, Michigan, USA.
Purpose: The purpose of this study was to verify the effect of our previously proposed mesiodistal distance for multiple posterior implants on preserving peri-implant bone, and to provide a measurable criterion for predicting implant prognosis.
Methods: One hundred and two patients with dental implants placed in the posterior free-end edentulous arches were recruited in this cross-sectional study. Calibrated X-rays (peri-apical [PA] or bite-wing x-ray) were collected to measure the mesiodistal space as well as the corresponding bone resorption of implants after prosthesis placement.
Icariin Facilitates Osteogenic Differentiation and Suppresses Adipogenic Differentiation of Bone Marrow Mesenchymal Stem Cells by Enhancing SOST Methylation in Postmenopausal Osteoporosis.

Department of Orthopedic Surgery, The Seventh Affiliated Hospital, Sun Yat-sen University, Shenzhen City, Guangdong, China.
Purpose: Postmenopausal osteoporosis (PMO) is mainly concerned with the imbalance of bone resorption and bone formation. Icariin (ICA) plays a vital role in bone protection. This study investigated the mechanism of ICA in PMO rats.

Department of Prosthodontics and Periodontology, Piracicaba Dental School, University of Campinas (UNICAMP), Piracicaba, SP, Brazil.
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: To study the clinical effect of the L-shape technique combined with concentrated growth factor on the horizontal bone defects of maxillary anterior teeth.
Methods: Twenty-five implants from 25 patients who underwent single maxillary anterior tooth implantation with simultaneous bone grafting were selected as the study subjects. Based on the bone grafting techniques, the patients were divided into a test group (L-shaped technique with guided bone regeneration combined with concentrated growth factor, 11 cases) and a control group (traditional guided bone regeneration combined with concentrated growth factor, 14 cases).
