Objective: To classify the paths of mandibular movements of patients with malocclusion.
Methods: 223 patients were examined clinically and mandibular Kinesiograph(MKG) was applied.
Results: Each kind of malocclusion has its corresponding characteristic paths of mandibular movement. The paths of mandibular movements of patients with the same class of malocclusion are similar. It was also found that the mandibular movement was related not only with occlusion but also with jaws, muscles, and joints. Meanwhile, they affect each other.
Conclusion: Functional malocclusion classification includes functional class I, II, III and IV malocclusion.

Introduction: Fiber posts present significant challenges for nonsurgical endodontic retreatment, as improper removal may result in iatrogenic root perforation or even root fracture. Recently, robotic technology has attracted considerable attention in dentistry and active dental robotic (ADR) systems can perform procedures based on preset instructions, minimizing reliance on the dentist's experience. This case report describes the application of an ADR system for fiber post removal through an existing zirconia crown.

Materials And Methods: Records of extraction (EXT) and nonextraction (NE) adult patients were identified from all patients treated with fixed appliances through the National Dental Practice-Based Research Network. Photographic Openbite Severity Index was used to assess treatment success and stability.
Jawline improvement using patient-specific angle implants with virtual planning in orthognathic surgery.

Department of Oral and Maxillo-Facial Surgery, Head and Neck Institute, University Hospital Center of Nice, 31 avenue de Valombrose, 06100, Nice, France; Nice Côte d'Azur Clinical Research Unit (UR2CA), France. Electronic address:
There has been a recent increase in the global demand for jawline augmentation. Managing angle definition in patients undergoing orthognathic surgery remains challenging owing to the characteristics of classic mandibular osteotomy, which mostly allows sagittal mandibular movements but cannot modify the ramus height. The advent of computer-assisted surgical planning and computer-aided design/computer-aided manufacturing techniques for patient-specific implant fabrication has introduced new methods for jawline management.

Department of Orthodontics, School of Dental Medicine, University at Buffalo, 3435 Main Street, Buffalo, NY 14214, United States.
Objectives: This study determined the prevalence and risks of definite sleep bruxism (SB) among children and adolescents presenting for orthodontic treatment.
Methods: This was a cross-sectional study of 7-16-year-old subjects pursuing orthodontic treatment for the first time. The presence or absence of SB was determined using an overnight mandibular movement monitoring inertial measurement sensor, worn by each participant for two consecutive nights.
