Por qué importa

Un estudio reciente ha investigado la conexión entre la estabilidad inicial de los implantes dentales, medida mediante el torque de inserción y la frecuencia de resonancia (ISQ), y la micromovilidad que experimentan bajo carga oclusal. Los hallazgos demuestran una correlación inversa significativa entre los valores de ISQ y el torque de inserción, y la cantidad de micromovilidad del implante. Es decir, a mayor estabilidad inicial, menor será el movimiento del implante bajo carga. Comprender esta relación es fundamental para predecir la posible estabilidad a largo plazo de los implantes y optimizar los resultados de los tratamientos, permitiendo tomar decisiones clínicas más informadas durante la planificación y la fase protésica.

Abstract original

PURPOSE: To evaluate the micromobility of dental implants under occlusal loading in relation to stability measurements of resonance frequency analysis and insertion torque. MATERIALS AND METHODS: The sample comprised of 24 implants inserted in 12 fresh cow ribs. Insertion torque and Osstell implant stability quotient (ISQ) measurements were recorded. An "ad hoc" acrylic premolar was made on a temporary abutment and screwed to each implant, and a force of 100 N was subsequently applied at an angle of 6 degrees. Implant micromotion was measured using a Questar microscope with a resolution of 2 μm and an image analysis program. RESULTS: Data show a statistically significant inverse correlation between the ISQ values and implant micromotion under a load of 100 N (R = 0.86, P < 0.0001). The same relationship is found between insertion torque and implant micromotion, although the relationship is linear up to 34 N·cm and becomes exponential for higher values (R = 0.78, P < 0.0001). A direct correlation is established between insertion torque and ISQ values. CONCLUSION: There is an inverse relationship between both ISQ and insertion torque values and implant micromotion under a load of 100 N.
