Résumé
Objectif de l’étude : Comparer l’impact de deux macro-conceptions d’implants différentes sur la stabilité primaire.
Matériel et méthodes: Les patients ont reçu des implants dans la mâchoire postérieure inférieure (os de type II et III). Deux implants macro-design différents ont été insérés au hasard conformément à un protocole de forage conventionnel, le premier est l’implant autotaraudeur hybride: Straumann® BL au niveau osseux et le second est un implant autotaraudeur conique: Straumann® BLT conique au niveau osseux.
16 implants (3,3 et 4,1 mm de diamètre, longueur comprise entre 8 et 10 mm) de chacun des deux implants susmentionnés ont été utilisés. L’évaluation primaire de la stabilité de chaque conception d’implant a été réalisée à l’aide de deux méthodes, enregistrant le couple d’insertion maximal IT (dispositif DTA) et enregistrant le quotient de stabilité de l’implant ISQ à l’aide de l’analyse de fréquence de résonance RFA (avec le dispositif Osstell).
Résultats : Dans tous les types d’os, les implants BLT ont montré un couple d’insertion moyen IT significativement plus élevé par rapport au BL avec respectivement 46,67±6,85 Ncm et 35,77±6,72 Ncm pour (p = 0,01 selon le test Anova), et un QIS moyen plus élevé avec respectivement 77,15±5,16 et 70,74±4,83. (p = 0,01 selon le test Anova).
Conclusion: Dans les os de type II et III, l’implant autotaraudeur conique (Straumann® BLT a statistiquement montré une meilleure stabilité primaire par rapport à l’implant autotaraudeur hybride: Straumann® niveau osseux BL. Dans les limites de la présente étude, on peut conclure que la macro-conception de l’implant peut être considérée comme un paramètre fiable pour atteindre une stabilité primaire acceptable des implants dentaires dans les zones à faible densité osseuse. Dans la présente étude, les deux méthodes utilisées pour évaluer la stabilité primaire des différents macro-modèles, l’évaluation du couple et l’appel de demandes, ont montré une faible corrélation. La macro-géométrie est essentiellement conçue pour satisfaire les besoins dans certaines situations osseuses critiques et dans le protocole de chargement immédiat.
