Objective: This observational study investigated the relationship between occlusal balance and the tightness of restorative-contralateral occlusal contact in patients undergoing dental implant restorations.

Methods: A total of 100 patients who received dental implant restorations at our hospital between July 2022 and July 2023 were included. Patients were divided into two groups based on occlusal closeness: an observation group (using 12 μm occlusal paper for occlusion) and a control group (using 20 μm occlusal paper for occlusion).

Objective: This case report presents the interdisciplinary retreatment of a patient with a worn full-mouth rehabilitation using defect-oriented restorations, horizontal preparations, and vertical dimension of occlusion (VDO) increase.

Clinical Considerations: A 58-year-old woman with a previous full-mouth rehabilitation presented with worn dentition, loss of VDO, and reduced posterior support. Examination revealed signs of parafunctional habits, tetracycline-stained teeth, and compromised aesthetics with exposed discolored teeth and open embrasure spaces.

Transient Receptor Potential (TRP) channels are a family of ion channels that play pivotal roles in various physiological processes, including sensory transduction, temperature regulation, and inflammation. In the context of dentistry, recent research has highlighted the involvement of TRP channels in mediating sensory responses and inflammation in dental tissues and temporo-mandibular joint (TMJ) structure. TRP channels have emerged as major contributors in the development of inflammatory conditions and pain affecting the oral cavity and related structures, such as periodontitis, dental erosion cause hypersensitivity, pulpitis, and TMJ disorders.

Background: Examining stress distributions in abutment teeth with periapical lesions is essential for understanding their biomechanical impact on dental structures and tissues. This study uses finite element analysis (FEA) to evaluate these stress patterns under occlusal forces, aiming to enhance treatment strategies and prosthetic designs.

Methods: Three FEA models were created: a healthy mandibular premolar (Model 1), a premolar with a single crown and a lesion repaired using a fiber-post (Model 2), and 3) a premolar with a lesion repaired using fiber-post to support a four-member bridge (Model 3).

Objective: To evaluate the clinical efficacy of clear aligner therapy in patients with severe periodontitis accompanied by pathological tooth displacement in the anterior region.

Methods: This retrospective study analyzed patients diagnosed with severe periodontitis and pathological displacement in the anterior region, who visited both the Periodontics and Orthodontics Departments at Peking University School and Hospital of Stomatology between 2019 and 2022. A total of 26 eligible cases were included in this study.
