onto an implant surface and into an implant structure.

Three-dimensional Three-dimensional space (also: 3D space, 3-space or, rarely, tri-dimensional space) is a geometric setting in which three values (called ''parameters'') are required to determine the position of an element (i.e., point). This is the informal ...

, porous implantable materials used in the orthopedic and dental implant industries offer the potential for ingrowth as well as ongrowth or osseoincorporation.

Comparison to osseointegration

Conventional textured or coated implant surfaces are designed to achieve bone-to-implant contact, which is called ''ongrowth''.

Per-Ingvar Brånemark Per-Ingvar Brånemark (May 3, 1929 – December 20, 2014) was a Swedish physician and research professor, acknowledged as the "father of modern dental implantology". The ''Brånemark Osseointegration Center'' (BOC), named after its founder, was fo ...

, they osseointegrate. Porous implantable materials are designed for bone to grow not only onto the material but also into its pores, and in some cases interconnecting within the material’s structure, in a process called ''osseoincorporation''.

Complications

In some cases, the patient has periodontal defects (damaged or poor bone structure) which hinder osseointegration. Guided tissue and/or bone regeneration may be necessary before the bone can osseointegrate with the

. In this case a combination of barrier membranes, bone tacks, and supplemental autogenous bone may be required to promote proper osseointegration. In addition, implant surface modification has been studied and now integrated, thus promoting an optimal tissue-implant interface (i.e. osseointegration, implant-gingival seal).F. Rupp, L.
