The Effects Of Modified Sandblasting Treatment On The Osteocompatibility Of Titanium Imlpant

Dental implants have been widely used in the clinics and more and more patients receive this treatment each year.However,there still exsita lot of problems which lie in the implant—tissue interface. The fundamental way to resolve it is to improve the biocompatibilities of biomaterials.Reviewing the biomaterial science's status quo,the author puts forward 'osteocompatibility' and defines it as the fact that the endosseous implant materials should favor the osseointegration in the bio—tissue compatibility ,and favor the stress distribution and mechanical transferring at the bone interface in the biomechanical compatibility , besides the prerequisite of meeting the basic biocompatibility.Furthermore,the author also brings forward 'biomaterial surface science',assuming that the surface characteristics of biomaterial be the main factors to determine the biological response to it.Of all the surface characteristics,the surface topography is the prevailing one to affect the osteocompatibility. We do know rough surface is advantageous,but we don't know which form is the perfect one. We employed the sandblasting technique modified with acid attack to improve the osteocompatibility of c.p.titanium and the possibility of its application in the dental titanium implant area was evaluated.Our study also revealed the mechanisms of its effects on the osteocompatibility to some extent.This paper is divided into five parts:...
