Implant Placement in Maxillary Esthetic Zone
Conditions
Brief summary
Immediate implant placement has a success rate from 94-100 % . After tooth extraction there is a loss in the horizontal and vertical dimension by about 3-6 mm and 1-2 mm respectively and alveolar crest resorption of about 44% especially through 6 months after extraction. After immediate implant placement there is usually a void between the implant and the socket walls which is called jumping distance or gap which may heal spontaneously or need bone graft to bridge the space. If the gap is 1-2 mm it may heal spontaneously more than that this will need bone graft. There is no evidence that the graft impairs osseointegration Development of artificial bone has increasingly progressed in the last few years. Nanobone nanocrystalline hydroxyapatite embedded in a porous silica gel matrix bone graft is introduced which has osseoconductive and biomimetic properties .the sub-micron modification in the bone substitute will enhance osteogenic property. It bind to the bone by stimulation of osteoblast activity and enhance growth factors which improve bone healing and provide more strength and stability to the implant.
