Abstract
Abstract: Objectives: The aim of this study was to analyze the bone density around immediately loaded oral implants by a new volumetric CT scan (Maxiscan) and to compare it with that of unloaded implants.

Quatre patients de 44 à 65 ans ont été sélectionnés pour cette étude. Ils nécessitaient tous une prothèse dans la partie postérieure du maxillaire ou de la mandibule. En tout, douze implants ont été placés chez ces quatre patients. Six de ces implants ont été mis en charge immédiatement et six ont eû une charge postposée. Six mois après le placement, les implants buccaux immédiatement chargés et ceux sans charge ont été analysés par un scanCT volumétrique. Le taux de succès général de cette étude avec des implants immédiatement mis en charge était de 100%. L'évaluation radiologique a montré un profil de densitométrie moyen, c'est‐à‐dire une mesure de la minéralisation osseuse, qui était supérieure dans le groupe avec charge immédiate par rapport au contrôle. Les différences observées entre les deux groupes étaient caractéristiques (p<0,05). L'os était significativement plus dense autour des implants immédiatement mis en charge qu'autour des contrôles sur base de l'évaluation radiologique.

<hi rend="italic">Objetivos</hi>: La intención de este estudio fue analizar la densidad del hueso alrededor de implantes inmediatamente cargados por medio de un nuevo escáner CT volumétrico (Maxiscan) y compararla con aquella de implantes sin cargar. <hi rend="italic">Material y Métodos</hi>: Se seleccionaron para este estudio cuatro pacientes con edades desde 44 a 65 años.
