Book excerpt: Assessment of implant stability by resonance frequency analysis in anterior and posterior segments of mandibulary edentuolus ridgesOne of the most important inventions in modern dentistry are dental implants. The process of osteointegration is a result of the initial mechanical stability complemented with biological stability. Osstell device was invented to measure the stability of dental implants at any time of the treatment.Aim/Hypothesis: The aim of this study was to analyze the implant stability quotient (ISQ) results of the resonance frequency (RF) in anterior and posterior segments of the lower jaw at the first day of placement of dental implants and 3 months after the surgery.Materials and Methods: This study was approved by forty patients with total or partial edentulous mandibular jaws underwent with 76 dental implants. The ISQ values were measured at the day of surgery and 3 months after placement. Osttell Mentor device was used to measure the RF value of the implant fixture through the transducer or pin. Measurements were taken four times in each direction of inserted oral dental implant.Results: The ISQ primary stability at the day of surgery had a mean value of 63.81 (SD 9.48) for dental implants in anterior segment of lower jaw and the secondary stability was 70.25. The mean ISQ of primary stability of the posterior segments of lower jaw was 63.89 (SD 6,99) while the secondary stability 69.43. Differences between primary and secondary mean ISQ values were statistically significant (p
