RESUMO

INTRODUCTION: The primary stability of dental implants is related to the bone in contact with the latter, and can be evaluated by resonance frequency analysis. MATERIAL AND METHODS: Measurements were made in 133 implants (62 in the upper jaw and 71 in the mandible) of resonance frequency and insertion force to determine implant stability on the day of surgery, with an evaluation of its relationship to different variables. RESULTS: The stability quotient of the implants on the day of surgery was 62.1, with an insertion force of 35.7 N. The insertion force was proportional to the resonance frequency, with an increasing stability quotient with growing insertion force. The stability quotient was greater in the larger diameter implants, shorter implants, in mandibular placement and in areas of more compact bone. CONCLUSIONS: The stability quotient on the day of implant placement is greater in higher bone density areas.

RESUMO

Introducción: La estabilidad primaria del implante dental está relacionada con el hueso que se encuentra en contacto con él y se puede medir mediante el análisis de frecuencia de resonancia. Material y métodos: En 133 implantes (62 en maxilar y 71 en mandíbula) se midió la frecuencia de resonancia y la fuerza de inserción para conocer la estabilidad de los implantes el día de la cirugía, y estudiar su relación con distintas variables. Resultados: El cociente de estabilidad del implante obtenido el día de la cirugía fue de 62’1 y el de la fuerza de inserción fue de 35’7 Nw. La fuerza de inserción fue proporcional al análisis de la frecuencia de resonancia, a mayor fuerza de inserción mayor cociente de estabilidad. El cociente de estabilidad fue mayor en los implantes de diámetro mayor, en longitudes más cortas, en las fijaciones colocadas en mandíbula y áreas de hueso más compacto. Conclusiones: El cociente de estabilidad el día de la colocación de los implantes es mayor en zonas óseas de mayor densidad
