Restoration of the occlusal relationship is the key point in the treatment of maxillofacial fractures. Poor restoration of the occlusal relationship seriously impacts oral function as well as physical and mental health. This study combines virtual surgical technology with model surgery, uses computed tomography data to establish a maxillofacial bone model, and performs a virtual reduction of fractures. The upper and lower dentition models after reconstruction were intercepted and 3-dimensional printed. After the occlusal relationship was reconstructed by the prosthodontist using the model, an occlusal reduction guide was designed and manufactured based on the reconstructed occlusal relationship to accurately reduce the occlusal relationship in patients with maxillofacial fractures. This study proposes an occlusal guide design process for maxillofacial fractures and optimizes the traditional model surgical process to provide a convenient surgical strategy. This study provides new ideas for the design of personalized surgical guides for maxillofacial fractures.

Background: Bite force is one of the important factors that determine the chewing efficiency of molars. This study aimed to investigate the relationship of the maximum bite force (MBF) to the 3-dimensional (3D) arrangement of the first mandibular molars in Angle's class I healthy adults using a digital protocol.
Material And Methods: Subjects were 33 adults (16 males and 17 females) aged 18-25, with Angle's class I occlusions and healthy dentitions.

Clinic of Reconstructive Dentistry, Center for Dental Medicine, University of Zurich, Plattenstrasse 11, CH-8032, Zurich, Switzerland.
Objectives: To evaluate clinical outcomes (restoration survival, technical and biological complications), and patient-reported outcome measures (PROMs) of full mouth rehabilitation with minimally invasive glass-ceramic restorations after up to 12 years of clinical service.
Materials And Methods: Twenty individuals (12 females, 8 males) received full-mouth rehabilitation with minimally invasive tooth-supported glass-ceramic restorations during the years 2009 - 2017 and agreed to participate in a follow-up visit. Full dental and periodontal examinations were completed, and the restorations were evaluated according to United States Public Health Service (USPHS) criteria.
Non-surgical correction of an adult Class II high-angle with occlusal plane cant by four compromised permanent first molars extraction, preadjusted lingual appliance and miniscrews: A case report.

Private Practice, Osaka, Japan.
This case report describes a complex full-step asymmetrical Class II division 1 high-angle in an adult patient treated by extraction of compromised first molars with a preadjusted lingual appliance. Since the patient presented severe sagittal and vertical discrepancies combined with an Izard orthofrontal profile with upper lip protrusion, an extraction camouflage was performed with the twofold aim of obtaining ideal occlusal relationship and profile improvement, correcting occlusal plane cant by selective intrusion with interradicular miniscrews. Appropriate biomechanical strategies, including extraction choice and anchorage control during space closure, were needed to achieve the planned results.

This research explores the types and effectiveness of occlusal splints in managing temporomandibular disorders (TMDs). TMDs encompass a range of musculoskeletal and neuromuscular conditions affecting the jaw, causing pain, limited movement, and discomfort. Occlusal splints, also known as bite guards, are commonly used in dentistry to alleviate TMD symptoms by relaxing jaw muscles, preventing joint trauma, and protecting teeth.

Objectives: To investigate the influence of different facial scanners and integration approaches on the accuracy of virtual dental patients (VDPs).
Methods: Forty VDPs were generated using a head mannequin and two facial scanners: 1) an industrial scanner and 2) a smartphone scanner. For each scanner, two integration methods were applied: 1) integration by virtual facebow scan and 2) integration by nose-teeth scan.
