Por qué importa

Este estudio aborda la influencia de la técnica de preparación del sitio del implante, específicamente el sobredimensionamiento del orificio, en la estabilidad primaria del implante. Se comparó la técnica convencional con una técnica de sobredesgaste, evaluando la estabilidad mediante el torque de inserción y el análisis de frecuencia de resonancia (RFA). Los hallazgos indican que el sobredesgaste resulta en menores valores de torque de inserción, sin afectar significativamente las mediciones de estabilidad obtenidas por RFA. Estos datos son relevantes para los clínicos al considerar los protocolos de preparación del sitio, sugiriendo que las diferencias en la preparación ósea pueden manifestarse de manera distinta en las dos metodologías de medición de la estabilidad primaria.

Abstract original

BACKGROUND: This study evaluated the influence of implant site preparation depth on primary stability measured by insertion torque and resonance frequency analysis (RFA). MATERIAL AND METHODS: Thirty-two implant sites were prepared in eight veal rib blocks. Sixteen sites were prepared using the conventional drilling sequence recommended by the manufacturer to a working depth of 10mm. The remaining 16 sites were prepared using an oversize drilling technique (overpreparation) to a working depth of 12mm. Bone density was determined using cone beam computerized tomography (CBCT). The implants were placed and primary stability was measured by two methods: insertion torque (Ncm), and RFA (implant stability quotient [ISQ]). RESULTS: The highest torque values were achieved by the conventional drilling technique (10mm). The ANOVA test confirmed that there was a significant correlation between torque and drilling depth (p<0.05). However, no statistically significant differences were obtained between ISQ values at 10 or 12 mm drilling depths (p>0.05) at either measurement direction (cortical and medullar). No statistical relation between torque and ISQ values was identified, or between bone density and primary stability (p >0.05). CONCLUSIONS: Vertical overpreparation of the implant bed will obtain lower insertion torque values, but does not produce statistically significant differences in ISQ values. KEY WORDS: Implant stability quotient, overdrilling, primary stability, resonance frequency analysis, torque.
