Por qué importa

Este estudio prospectivo evalúa los cambios en la estabilidad de los implantes dentales, medidos mediante análisis de frecuencia de resonancia (RFA) con Osstell Mentor, durante el proceso de oseointegración. Se compararon implantes con carga inmediata frente a implantes control sin carga en pacientes. La medición del cociente de estabilidad del implante (ISQ) se realizó al inicio, a las 6 y a las 8 semanas. Los resultados indican que la carga inmediata puede aplicarse con valores de estabilidad primaria de ISQ superiores a 60 y una fuerza de inserción de al menos 30 N. El método RFA se presenta como una herramienta objetiva para determinar la idoneidad de la estabilidad del implante antes de proceder a la carga inmediata, lo cual es fundamental para optimizar los resultados clínicos y la planificación del tratamiento en la práctica diaria.

Abstract original

Aim: The aim of this prospective clinical study was to evaluate the changes in resonance frequency analysis (RFA), assessed by Osstell Mentor, obtaining information on the implant stability quotient (ISQ) during implants tissue integration for immediately loaded and non-loaded control implants. Materials and methods: A total of 40 implants, 20 implants with no immediate loading (control) and 20 immediately loaded implants (test), were placed in 15 patients. ISQ implants was evaluated at baseline and at 6 and 8 weeks. Provisional crowns were removed at 8 weeks, when the definitive restoration was placed. Data of control and test implants and maxillary and mandibular areas were statistically compared. Results: At 8 weeks, all implants were integrated and there were no major postoperative complications. A statistically significant difference was found only at baseline between test and control maxillary implants (p=0.009) but not at 6 or 8 weeks (p>0.05). Conclusion: Immediate loading procedures may be applied with primary stability ISQ values >60 and inserted with a force of ≥30 N. The Osstell Mentor RFA may offer an objective method to determine when implant stability is adequate for immediate loading.
