Brief Summary

Dental implants are currently accepted as a most predictable treatment option for the rehabilitation of both partial or total edentulous patients. During the early phases of healing, dental implants should be protected from detrimental micromovements which, according to the literature, should not exceed values ranging from 50 and 150 μm to avoid risks for the osseointegration. When exceeding this threshold, there is a concrete possibility that the bone implant interface could be colonized by fibroblasts from the overlying connective tissue, with consequent implant encapsulation in fibrous tissue and clinical failure.

Numerous noninvasive methods have been proposed to evaluate implant stability, but the most widespread techniques are implant insertion torque measurement (IT) and resonance frequency analysis (RFA).

Till date, insertion torque value (ITV) and implant stability quotient (ISQ) obtained by the Osstell instrument are common clinical methods to assess the initial stability of an implant for a predictable loading procedure. Primary stability is described as the result of bone compression during implantation. Good primary stability is essential for the prevention of implant micro-movements and in order for bone remodeling and osseointegration around the implant to be achieved.

Secondary stability is referred to as biological stability that develops as a consequence of the formation and remodeling of alveolar bone on the implant surface .

There are three protocols for implant loading:

(1) immediate loading, prosthesis may be placed in occlusion up to 72 hours after implant placement.

(2) early loading, prosthesis may be placed in occlusion between 1 week and 2 months after implant placement.

(3) delayed loading, prosthesis may be placed in occlusion from 3 to 8 months after implant placement.

Insertion torque was developed by Johansson and Strid and improved by Frieberg in the 1990s.According to Baldi et al, the insertion torque is applied with a torque wrench, and it is the measure of the frictional resistance encountered by the implant while moving forward apically through a rotatory movement on its axis. Thus, this method provides information about bone quality at the implant placement site and implant primary stability. The RFA was developed in the late 1990s by Meredith.

The RFA methodology is based on the quantitative assessment of implant micro deflection. According to Herrero-Climent et al, the RFA is a noninvasive diagnosis technique that uses a piezoelectric transducer, which emits a sinusoidal signal within a specific frequency, resulting in implant vibration. The implant resistance to vibration is measured by the device and transformed into the implant stability quotient (ISQ, within a 0–100 scale; 100 being maximum implant stability). Clinically, RFA has been used to assess the implant primary stability and stability over time. Therefore, the RFA allows to check and identify the risk of failure of an implant before it occurs.
