“…It has clearly been shown to accurately assess implant osseointegration, since it has been positively correlated to bone‐to‐implant contact (BIC) in the course of the biological integration process (Meredith, Shagaldi, Alleyne, Sennerby, & Cawley, ). This finding was further evidenced in the clinical setting (Monje, Suarez, et al, ), where the healing pattern conditioned by the maxillary/mandibular implant site dictated the implant stability quotient (ISQ) (Huwiler, Pjetursson, Bosshardt, Salvi, & Lang, ). However, more controversial evidence is found on assessing the accuracy of RFA in predicting implant failure (Huwiler et al, ; Monje, Ortega‐Oller, et al, ), questioning the usefulness of its routine use in monitoring implant stability over time.…”

Objectives: To investigate the impact of progressive bone loss in an experimental peri-implantitis model in the dog upon the implant stability quotient (ISQ) measured in the course of induced and spontaneous conditions of disease, and to evaluate the association between the clinical parameters and ISQ. Materials and Methods: Seventy-two implants were placed in 12 Beagle dogs. Of these, 36 implants in six dogs were assessed during ligature-induced peri-implantitis (three timepoints) and at one timepoint following a period of spontaneous progression. The ISQ was recorded using resonance frequency analysis (RFA). Furthermore, the clinical peri-implant parameters were registered at four sites per implant at each timepoint. Marginal bone loss (MBL) was determined using computed tomography at four sites per implant and bone-to-implant contact (BIC) was assessed from histological samples. A linear regression model was estimated by generalized estimation equations (GEEs) in order to study the MBL-ISQ values at each measurement timepoint. Pearson's correlation test was applied.Results: None of the implants failed during the study period. At implant level, a strong negative correlation was found for all timepoints between ISQ and MBL (r = −0.58; p < 0.001). Accordingly, as follow-up progressed, lower ISQ and higher MBL values were observed. A prediction of MBL depending on the ISQ values and timepoints showed a decrease in one ISQ unit to be related to ~1 mm of MBL.Likewise, a statistically significant correlation was found between BIC and ISQ evaluated after spontaneous chronification of peri-implantitis (r = 0.34; p = 0.04).Nevertheless, the ISQ values failed to correlate to any of the clinical parameters recorded.Conclusion: Resonance frequency analysis seems accurate in diagnosing progressive bone loss, as a statistically significant decrease in ISQ was recorded in the course of peri-implant disease. Nevertheless, the clinical relevance of this observation as a diagnostic tool is debatable, since implant stability remains high.

“…An implant-supported full bridge or full denture may be the ideal therapy to resolve problems that can arise due to the use of conventional dentures. Although the cost is relatively high, numerous advantages of using dental implants make this therapy the first choice for the replacement of missing teeth [23,24]. The present study emphasizes the importance of maintaining the jawbone height after tooth extraction through the proposed ideal therapy toward the minimization of the rate and amount of mandibular bone atrophy in elderly patients.…”

Objectives: The severity of jawbone atrophy differs among individuals and even within an individual. This study investigated the relationship between vertical mandibular bone atrophy and the number of remaining teeth in elderly Indonesian individuals. Material and methods: A total of 148 panoramic radiographs of patients aged ≥ 50 years were selected from dental records at the Radiology Department, Dental Hospital Faculty of Dentistry, Universitas Indonesia, in 2017. To measure vertical mandibular bone atrophy, a vertical line was created running from the crest of the alveolar ridge to the most inferior point of the mandibular inferior cortex through the center of the mental foramen. Subjects were first divided into four groups based on the number of remaining teeth: group I had 1-8 remaining teeth, group II had 9-16, group III had 17-24, and group IV had 25-32. Results: The number of remaining teeth was significantly associated with vertical mandibular bone atrophy. Mean differences and standard deviations for vertical mandibular bone atrophy were significantly higher in groups III and IV patients than in group I and II patients (group I vs. group III: 5.2 ± 1.7, p = 0.016; group I vs. group IV: 5.8 ± 1.6, p = 0.005; group II vs. group III: 3.2 ± 1.1, p = 0.023; and group II vs. group IV: 3.8 ± 1.1, p = 0.003). Patients with fewer remaining teeth were 1.78 times more at risk for a decrease in their mandibular bone volume than those with more remaining teeth. Males were 1.78 times more likely to have a higher mandibular bone volume than females. Conclusion: Mandibular bone atrophy was significant in patients with fewer than half of the total number of teeth remaining.
