Abstract  

Objectives: To assess primary and secondary stability of titanium-zirconium alloy dental implants using resonance frequency analysis, and to identify factors influencing implant stability.

Materials and Methods: This was a longitudinal, prospective study utilizing the Straumann® implant system with either conventional or guided implant bed preparation techniques. Implant stability was measured using the Osstell ISQ® system (Integration Diagnostics AB, Gothenburg, Sweden) and analyzed in relation to patient-specific, implant-related, and surgical variables using multilevel modeling and multiple linear regression.

Results: A total of 274 implants were placed in 107 patients. Primary stability was positively correlated with bone density and insertion torque (p < 0.05). Higher primary stability was observed with 10 mm and 12 mm implants compared to 8 mm implants. Guided implant bed preparation resulted in higher and more consistent primary stability than conventional techniques. Patients with endocrine disorders demonstrated a reduction in ISQ values, with decreases of 5.63 units in the vestibular/palatal (ISQ Vb/PLv) and 6.07 units in the mesial/distal (ISQ M/Dv) directions. Greater increases in stability were observed in cases of caries-related tooth loss compared to periodontal disease, and with the use of longer and wider-diameter implants.

Conclusions: These findings underscore the value of standardized methods for assessing implant stability and highlight the relevance of patient-, implant-, and procedure-related factors in predicting implant success.
