Abstract

Summary The purpose of this follow‐up study was to measure the resonance frequency of Astra Tech TiO2 blasted implants at second surgery, at one and 3 years of loading. Secondly, it was investigated whether resonance frequency at second surgery could discriminate between successful implants and those that will fail over a 3‐year period. Fifty titanium dioxide‐blasted implants in eight consecutive patients with edentulous maxillas seeking fixed rehabilitations, were included in the study at abutment connection after 6 months of healing. Resonance frequency, clinical and radiographic records were obtained at abutment connection and after one and 3 years of loading. The cumulative survival rate after 3 years was 100%. The mean resonance frequencies were 65 ± 4·8 implant stability quotient (ISQ) at second surgery (range 50–78 ISQ), 66 ± 3·4 ISQ after 1 year of loading (range 53–76 ISQ) and 64 ± 3·8 ISQ after 3 years of loading (range 53–77 ISQ). No significant differences resulted between these three time points. The marginal bone level decrease of 0·6 mm between the second surgery and the 3‐year follow‐up was observed. One limitation of the study is that no late failures were encountered in this relatively small sample. Consequently, it was not possible to establish a cut‐off ISQ for implants that, after abutment connection, would maintain their stability over a 3‐year period. Nevertheless, it might be concluded that following the first year of loading the range of 53–76 ISQ describes the stability of osseointegrated Astra Tech TiO2 blasted implants.

<abstract>Summary  The purpose of this follow‐up study was to measure the resonance frequency of Astra Tech TiO2 blasted implants at second surgery, at one and 3 years of loading. Secondly, it was investigated whether resonance frequency at second surgery could discriminate between successful implants and those that will fail over a 3‐year period. Fifty titanium dioxide‐blasted implants in eight consecutive patients with edentulous maxillas seeking fixed rehabilitations, were included in the study at abutment connection after 6 months of healing. Resonance frequency, clinical and radiographic records were obtained at abutment connection and after one and 3 years of loading. The cumulative survival rate after 3 years was 100%. The mean resonance frequencies were 65 ± 4·8 implant stability quotient (ISQ) at second surgery (range 50–78 ISQ), 66 ± 3·4 ISQ after 1 year of loading (range 53–76 ISQ) and 64 ± 3·8 ISQ after 3 years of loading (range 53–77 ISQ). No significant differences resulted between these three time points. The marginal bone level decrease of 0·6 mm between the second surgery and the 3‐year follow‐up was observed. One limitation of the study is that no late failures were encountered in this relatively small sample. Consequently, it was not possible to establish a cut‐off ISQ for implants that, after abutment connection, would maintain their stability over a 3‐year period. Nevertheless, it might be concluded that following the first year of loading the range of 53–76 ISQ describes the stability of osseointegrated Astra Tech TiO2 blasted implants.</abstract>
