概要	Bone density assessment in dentistry evaluates the quantity and quality of alveolar bone supporting teeth or serving as an implant site. Assessment integrates radiographic imaging (panoramic radiographs, periapical films, and cone-beam computed tomography) and clinical examination to classify bone density into four categories (Type I to IV) and to quantify bone loss. Accurate bone density assessment is critical for implant planning, predicting implant success, and adjusting surgical and loading protocols to account for bone quality variations.	Occlusal analysis is a systematic clinical and instrumental examination that evaluates the relationships between the maxillary and mandibular teeth, the temporomandibular joint, and the muscles of mastication. Comprehensive occlusal analysis informs diagnosis of malocclusion, temporomandibular disorders, and guides prosthodontic and orthodontic treatment planning. The analysis integrates static occlusal relationships (centric relation, centric occlusion) with dynamic occlusal patterns (jaw movements) to assess functional harmony and identify occlusal interferences.
