Résumé

The influence of dental implant length and diameter on primary stability in various bone densities is not well understood. To in vitro study the effect of length and diameter on resonance frequency analysis (RFA), insertion torque (IT) and displacement (DP) measurements of dental implants in different implant site densities. Dental implants of four different diameters (Ø 3.5, 4.0, 4.5 and 5.0 mm) and three different lengths (7, 11 and 15 mm) (Neoss Ltd, Harrogate, UK) were placed in polyurethane blocks of three different densities (Sawbones Europe AB, Malmö, Sweden). The primary stability was assessed by RFA (ISQ) (Osstell, Osstell AB, Gothenburg, Sweden) and insertion torque measurements (IT Implant length, diameter and block density were found to be significant independent predictors of RFA, IT Implant length affects primary stability more than implant diameter in polyurethane blocks of uniform density along the whole length of the tested implants.

BACKGROUND BACKGROUND

The influence of dental implant length and diameter on primary stability in various bone densities is not well understood.

AIM OBJECTIVE

To in vitro study the effect of length and diameter on resonance frequency analysis (RFA), insertion torque (IT) and displacement (DP) measurements of dental implants in different implant site densities.

MATERIALS AND METHODS METHODS

Dental implants of four different diameters (Ø 3.5, 4.0, 4.5 and 5.0 mm) and three different lengths (7, 11 and 15 mm) (Neoss Ltd, Harrogate, UK) were placed in polyurethane blocks of three different densities (Sawbones Europe AB, Malmö, Sweden). The primary stability was assessed by RFA (ISQ) (Osstell, Osstell AB, Gothenburg, Sweden) and insertion torque measurements (IT

RESULTS RESULTS

Implant length, diameter and block density were found to be significant independent predictors of RFA, IT

CONCLUSIONS CONCLUSIONS

Implant length affects primary stability more than implant diameter in polyurethane blocks of uniform density along the whole length of the tested implants.
