Implant and surrounding tissue after implantation of the interface with the success or failure is directly related to planting, the emergence of bio-active material has opened up to address the interface with a new way, on the basis of domestic and foreign scholars to design a variety of shapes and composite materials dental implant. This paper is a brief overview.

After implantation of the implant stability is the key to successful cultivation, its interface with the organization to determine whether the morphology is the basic means to achieve growing success and key indicators.

Branemark in the late 1960s made osseointegration (Osseo_integration) concept: meaning that the activity of dental implant and bone tissue with persistence of bone contact interface without fiber intervention

1. Titanium is the first clinical application of planting material, Young and other animals implanted titanium bone implant, bone to obtain a good combination of interface, ie osseointegration

2. Clinical studies have confirmed that the titanium implant and bone to achieve a higher osseointegration

3. In recent years, the rise of the use of the implant surface micro-structure of the combination of technology to solve the interface problem. The common technique is to allow the porous surface of the implant, the surrounding tissue grew into the pores to be formed after the organization intertwined with the How to do porcelain dental inflammation implant interface, so that the porous surface and produces mechanical lock between the results of bone strength (mechanical interlock), increased the stability of the implant, Zhanghui Qiu et al experiment also confirmed this

4. Biologically active materials (bioactive materials) the emergence of combination to address the interface opens up a new way. Such materials can be controlled by surface chemical reactions have a choice, the organization formed with the biochemical binding. Planting material in the bone, generally that the calcium phosphate glass type and class of biological activity of biological material, Yang Xiaodong (1987) tested the smooth surface of the dense type of bioactive glass ceramic and zirconia ceramic and hydroxyapatite bone interface shear strength , and the results compared with the control of the cobalt-chromium-molybdenum alloy to be 7-9 times higher.

5. Suggesting the formation of chemical combination. Kay (1988) further proposed a biological combination Biointegration) concept, which can not provide sufficient mechanical combination lock knot strength is the combination of biological [6]. The past 20 years, scholars integrated the advantages of various materials, shapes and design a variety of dental implant composite materials, including bioactive implant to Implant the life of any decision adapt the direction of the development of Oral Implantology, and has broad application prospects. At present, mainly used in clinical and research focus on the biological activity of dental implant are: Hydroxyapatite coating of titanium core surface (HA) implants, titanium core bioactive glass ceramic implants, titanium core with bone morphogenetic protein composite implant , titanium porous bioactive ceramics and bone morphogenetic protein composite dental implant, dental implant titanium nitride. This paper on the biological activity and bone implant interfacial bonding between the histological response to the situation and make a brief review.
