Success of complex or basic implant treatments based on providing implant stability. Every stage of the treatment, stability stands as a criterion for planning.  The overall stability of the implant combines with the mechanic and biological stages. Primary stability comes from mechanical engagement of implant with cortical bone while secondary stability develops after tissue regeneration and remodeling [1]. Driving force of the secondary stability is the adequate primary stability [1].

Stability tends to be evaluated with combining patient parameters, surgical protocols, and clinician parameters [2]. Primary stability is affected by bone quantity and quality, surgical technique the professional follows and implant characteristics as geometrical features, surface characteristics etc. whereas secondary stability is affected by primary stability. [1,3]

Stability has been hot topic for research on implantology field. As a result, many methods are improved for measure implant stability. The gold standard method of evaluating osseointegration depends on histologic or histomorphometric analysis [1,3]. It is not widely used technique regarding to unnecessary biopsies for stability assessment [4]. There are many methods used for evaluating the stability with quantitative and qualitative measurements in practice. As the dental technology opens the door for welcoming digital innovation for more specific findings, prediction methods are designed with the help of physics and field of electronics.

Radiographic evaluation is the non-invasive method that protects its validity within all the treatment stages [3]. Cutting torque resistance analysis (CRA), on the other hand, determines low density bone area and quantifies bone hardness by using electric motor at the surgery time simultaneously [1]. After the adaptation of vibrational methods into the dental field, the modal stability measurement tools were joined in the literature and in practice as well. In the vibrational or modal analysis, measures the natural frequency or displacement signal of a system in resonance, which is initiated by external steady-state waves or a transient impulse force by theorical and experimental models [1]. They are both used to quantify the degree of osseointegration and implant stability [4]. Percussion test, impact hammer test (periotest etc.) and more trend one as RFAs (resistance frequency analysis) used this technological basis [3]. Measurement procedures finalize with numeric values as PVC or ISQ from Periotest and RFA respectively [3].

Implant stability is an important and required milestone for patient’s implant journey from beginning to end. For primary stability, implant related factors should be considered. NUVO InternalFIT and ConicalFIT implant families have tapered implant design with proven Ti Gr4 material in different diameter and height options.  For more information about us, please visit NUVO implants website from here.
