概要	Resonance Frequency Analysis (RFA) is a non-invasive, objective method for assessing dental implant stability and osseointegration. Introduced by Meredith and colleagues in 1996, RFA measures the stiffness of the implant-bone interface by analysing the frequency response of an implant abutment to vibration. The Implant Stability Quotient (ISQ), derived from RFA, enables quantitative monitoring of implant stability at insertion, during healing, and post-integration, facilitating clinical decision-making regarding loading timing and success prediction.	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.
