Abstract

A structural/biological implant and method of use. The implant being utilized as a single or multiple staged system that is designed to encourage new alveolar bone growth with or without the need to obtain autologous bone. The implant has an apical portion that is fastened into existing bone, with the remainder of the implant left outside of existing bone. The exposed portion of the implant may have an external shape or configuration with a variety of attached and/or integrally formed mechanical retention and stability elements. Osteotropic/angiotropic material may be associated with the implant to induce and or conduct new bone growth and possible vascularization, thus, rather than fitting the implant into the bone, the bone is grown integratively with the implant.

Claims30

Dependent claims

An implant for promoting the growth of new vertical bone beyond existing bone level, comprising:

an initial implant portion having at its apical end a fastening means for directly embedding into direct contact with existing bone and having a coronal end that is configured to be proximal to existing bone level;
an osteointegrative portion disposed at the coronal end of the initial implant portion and which is configured to be substantially situated beyond the existing bone level, wherein said osteointegrative portion further comprises an osteotropic/angiotropic material disposed thereon;
and
an osteotropic/angiotropic stabilizer disposed at the coronal end of the osteointegrative portion and which prevents movement of the osteotropic/angiotropic material;
and
a preliminary stabilizer disposed generally at the coronal end of the initial implant portion for providing lateral and/or retentive stability to the initial implant portion during and/or after growth of new bone on the implant;
wherein said implant promotes the growth of new vertical bone along the osteointegrative portion beyond the existing bone level.
