Current trends to measure implant stability

ABSTRACT

Implant stability plays a critical role for successful osseointegration. Successful osseointegration is a prerequisite for functional dental implants. Continuous monitoring in an objective and qualitative manner is important to determine the status of implant stability. Implant stability is measured at two different stages: Primary and secondary. Primary stability comes from mechanical engagement with cortical bone. Secondary stability is developed from regeneration and remodeling of the bone and tissue around the implant after insertion and affected by the primary stability, bone formation and remodelling. The time of functional loading is dependent upon the implant stability. Historically the gold standard method to evaluate stability were microscopic or histologic analysis, radiographs, however due to invasiveness of these methods and related ethical issues various other methods have been proposed like cutting torque resistance, reverse torque analysis, model analysis etc. It is, therefore, of an utmost importance to be able to access implant stability at various time points and to project a long term prognosis for successful therapy. Therefore this review focuses on the currently available methods for evaluation of implant stability.

Mentions: Quantifies the mobility of an implant by measuring the reaction of the peri-implant tissues to a defined impact load. The Periotest was introduced by Schulte to perform measurements of the damping characteristics of the periodontal ligament, thus assessing the mobility of natural tooth.[2728] Periotest® [Figures 1 and 2] uses an electro-magnetically driven and electronically controlled tapping metallic rod in a handpiece. Periotest value range from −8 (low mobility) to +50 (high mobility). It can measure the bone density at the time of implant placement and postsurgical placement of the implant. Response to a striking or “barking” is measured by a small accelerometer incorporated into the head. The reliability of this method is questionable because of poor sensitivity, susceptibility to many variables.[29]
