Grafting of deproteinized bone particles inhibits bone resorption after maxillary sinus floor elevation

Abstract

Slowly resorbed deproteinized bone particles contribute to stable augmentation of the maxillary sinus floor by inhibiting bone resorption.

Insulin promotes bone formation in augmented maxillary sinus in diabetic rabbits

“…Insulin treatment reversed the decrease in bone formation, blood vessels, osteoblasts, collagen I and serum osteocalcin (P < 0.01). Insulin treatment also promoted osteogenesis in the augmented space of the diabetic rabbits, which might have resulted from promotion of osteoblast differentiation and upregulation of neovascularization.The maxillary sinus graft procedure, also referred to as maxillary sinus floor elevation, is a well-established technique for increasing bone volume in the posterior edentulous maxilla before dental implant insertion 22,23,26,30,31 . This technique has been performed by increasing numbers of implant surgeons because of its effectiveness and relatively low risk, but it is now known that uncontrolled diabetes is a contraindication for dental implants 18 .…”

SEM-EDX Study of the Degradation Process of Two Xenograft Materials Used in Sinus Lift Procedures

“…The crystallinity, grain size, surface bioactivity and density of the surface seem to have a less significant effect on osteoclastic activity. In addition, the topography of the scaffold surface can be tailored to affect the development and spread of osteoclast cells [75]. This suggests that resorption of collagen deproteinized bone material occurs more quickly than bone formation.…”

Elevación de piso de seno maxilar con técnica de Osteótomos

“…Tanto en casos en los que la técnica se haga de forma inmediata es decir la colocación de los implantes en la misma cirugía, como en los que la colocación se realiza en forma diferida, los tejidos blandos podrán ser manipulados y obtener así un perfil de emergencia correcto (15,18). Barone et al en el 2008, evaluó el éxito clínico de la colocación de implantes en alveolos frescos con elevación de piso de seno simultanea usando la técnica del osteótomo.…”

“…Es decir que la elevación de la membrana el seno tiene un comportamiento similar a la ROG; los injertos osteoconductores son el soporte para evitar el colapso de la membrana permitiendo además que en sus intersticios se forme una red vascular y la formación de nuevo hueso fase I embrionario o inmaduro, que por mecanismos de reabsorción y reemplazo se transforma en hueso fase II laminar o maduro (4,14,15).…”
