Role of primary stability for successful osseointegration of dental implants: Factors of influence and evaluation

Abstract

A secure implant primary (mechanical) stability is positively associated with a successful implant integration and long-term successful clinical outcome. Therefore, it is essential to assess the initial stability at different time-points to ensure a successful osseointegration. The present study critically reviews the factors that may play a role in achieving a successful initial stability in dental implants. Databases were searched from 1983 up to and including October 2013 using different combinations of various keywords. Bone quality and quantity, implant geometry, and surgical technique adopted may significantly influence primary stability and overall success rate of dental implants.

Differentiation of Osteoblast and Osteoclast Cells on Hydrogenated-Tetrahedral Amorphous Carbon Coated Titanium

“…It is considerably important to acquire the early and strong osseointegration and the long-term stability for success of the implant treatment [22,23]. there are numerous reports regarding modification of titanium to obtain stronger osseointegration to improve the bone compatibility.…”

Overview of Nanoparticle Coating of Dental Implants for Enhanced Osseointegration and Antimicrobial Purposes

“…Such a fixation is considered to be a requirement for implantsupported prostheses and their long-term success (10). The properties of bone surroundings extensively influence implant osseointegration and then, affect the shape and contour of the overlying soft tissues and therefore, the esthetic outcome (11). To achieve successful functional and esthetic treatment results, careful consideration of biologic principles of peri-implant soft and hard tissues, as _________________________________________ well as suitable selection of implant type and location are necessary (12).…”

Combining the effects of undersized drilling and bone density on implant insertion torque

“…The insertion torque obtained during the surgical moment of implant placement is essential to improve the primary stability, and consequently, to generate a successful osseointegration, especially during the immediate loading procedure 1,2 . Primary stability is defined as the absence of implant movement achieved after implant placement, and it depends of the implant design, bone density and surgical preparation technique 3,4 .…”

“…Therefore, the undersized drilling technique recommends a site preparation smaller than the diameter of the implant, providing a press-fit situation in which strain propagates into the supporting bone. This so-called undersized drilling technique was introduced with the aim to locally optimize bone density and consequently improve the insertion torque and the primary stability of the implant 2,[12][13][14] . This possibility becomes interesting mainly in situations of low bone density, where the direct contact with the implant surface will be smaller.…”
