“…Quesada-García et al [30] reported that a larger implant diameter had a positive effect on initial stability, while Boronat López et al [31] claimed that there was no association between implant diameter and stability. In our study, among SLA implants, the 5-mm implants had a significantly higher mean ISQ, suggesting that a larger implant diameter had a positive effect on initial stability.…”

PurposeThe possibility of immediate or early loading has become popular in implant dentistry. A prerequisite for the immediate or early loading of an implant prosthesis is the achievement of initial stability in the implant. Moreover, in response to clinicians' interest in verifying clinical stability to determine the optimal time point for functional loading, a non-invasive method to assess implant stability has been developed on the basis of resonance frequency analysis (RFA). The primary objective of this study was to monitor the stability of sandblasted, large-grit, and acid-etched (SLA) implants with different diameters during the early phases of healing by RFA. The secondary objective was to evaluate how the initial stability of implants varied depending on different surface modifications and other contributing factors.MethodsThirty-five implants (25 SLA implants and 10 resorbable blasting media [RBM] implants) placed in 20 subjects were included. To measure implant stability, RFA was performed at baseline and at 1, 2, 3, 4, 6, and 10 weeks after surgery.ResultsThe longitudinal changes in the implant stability quotient (ISQ) values were similar for the SLA implants with different diameters and for the RBM implants. During the initial healing period, the ISQ decreased after installation and reached its lowest values at 1 week and 2 weeks, respectively. The mean ISQ values in the SLA implants were significantly higher in Ø 5.0 mm implants than in Ø 4.0 mm implants. Men showed a higher ISQ than women. Mandibular sites showed a higher ISQ than maxillary sites.ConclusionsAll implants used in this study are suitable for immediate or early loading under appropriate indications. A wider diameter and SLA surface treatment of implants could improve the stability, if the implant is fixed with at least 30 Ncm of insertion torque.

“…This finding has been attributed by several authors to the presence/absence of cortical bone, which is 10 to 20 times stiffer than trabecular bone, which most likely also explains differences between mandibular and maxillary implants, since maxillary bone is often softer owing to lesser extents of cortical bone [8][9][10][11] (Chart 3).…”

“…From a clinical standpoint, it is important to realize that during the early weeks of healing, a decrease in implant stability may have to be ex pected owing to the loss of mechani cal stability. Following this period, an increase in clinical stability should be achieved by biological bonding [8][9][10].…”

Implant stability plays a critical role for successful osseointegration, which has been viewed as a direct structural and functional connection existing between bone and the surface of a load-carrying implant. Achievement and maintenance of implant stability are prerequisites for successful clinical Outcome. Therefore, measuring the implant stability is an important method for evaluating the success of an implant.The aim of this clinical study was to measure the implant stability quotient using a method called resonance frequency analysis of dental implants during the healing period. Material and methods:A number of 43 patients received 152 Shark AL-Technology implant system either in the maxillary or in the mandibular arch. Implant stability was measured with an Osstell Mentor device (Osstel, AB, Sweden) using the resonance frequency analysis at the time of implant placement, 0, 2, 4, 8 and 12 weeks post insertion. Results:The mean implant stability quotient for all implants placed was 72,18. The lowest value of the implant stability quotient was at 2 weeks post insertion measuring 60,78. Conclusions:In relation to the gender the implants placed in female patients showed a higher mean value of the implant stability quotient. In relation to the location within the dental arch the implants placed in the anterior areas had a higher implant stability quotient than the ones places in the posterior areas of the arch.
