Initial stability of placed implants and development of osseointegration are two major issues in patients. Implant stability is a position-related mechanical phenomenon which is related to the Bone. Bone quantity and quality, surgical technique including surgeon skill,implant (shape, length, diameter and surface features) are the main factors affecting initial stability. Primary stability, bone modeling and reconstruction, and implant surface condition are the main parameters affecting secondary stability. As briefly discussed implant RFA is influenced by many factors, including implant surface characteristics and placement location, bone quality, bone mass, marginal mucosa cushioning effect, and osteoimplant contact. may receive Effective implant length and connection to transducer. RFA as a technique for measuring the stability of dental implants has attracted considerable scientific interest in recent years since its initial introduction.
