الملخص	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.	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.
