Background: To improve the success rate of mini-implants, some surgical guides have been developed through digital technologies to achieve three-dimensional (3D) guided mini-implants insertion. However, there is no a surgical guide which can be applied for the insertion of infrazygomatic mini-implant. In this study, we introduced a two-trajectories surgical guide and investigated the success rate of infrazygomatic mini-implants under the guidance of the template.

Disuse bone loss is prone to occur in individuals who lack mechanical stimulation due to prolonged spaceflight or extended bed rest, rendering them susceptible to fractures and placing an enormous burden on social care; nevertheless, the underlying molecular mechanisms of bone loss caused by mechanical unloading have not been fully elucidated. Numerous studies have focused on the epigenetic regulation of disuse bone loss; yet limited research has been conducted on the impact of RNA modification bone formation in response to mechanical unloading conditions. In this study, we discovered that mA reader IGF2BP1 was downregulated in both osteoblasts treated with 2D clinostat and bone tissue in HLU mice.

To investigate the bone augmentation effects of domestic decellularized porcine small intestinal submucosa (PSIS) absorbable biomembrane and domestic bovine pericardium tissue (BPT) absorbable biomembrane in guided bone regeneration (GBR) for single-tooth implantation in diabetic patients. A prospective case-control study was conducted with 48 diabetic patients who received single-tooth implant restoration at the Department of Prosthodontics, School of Stomatology. The Fourth Military Medical University, between January 2023 and January 2024.

Implant failure remains a significant challenge in oral implantology, necessitating a deeper understanding of its risk factors to improve treatment outcomes. This study aimed to enhance the clinical outcomes of oral implant restoration by investigating the factors contributing to implant failure in patients with partial dentition defects within two years of treatment. Additionally, the study sought to develop an early risk prediction model for implant failure.

Department of Otomicrosurgery, Sixth Medical Center of The PLA General Hospital, Beijing, China.
Background: In some rare cases of congenital aplasia of the oval window (OW), malformed facial nerve (FN) locations covering the most or entire OW present a challenge to hearing reconstruction, there is no a highly effective surgical hearing reconstruction methods.
Aims/objectives: To update a Scala tympani drill-out technique (SDT) for abnormal FN course covering the OW.
Material And Methods: All patients of congenital atresia of the OW was recruited between August 2014 and July 2023 in a tertiary-care center.
