Additive Surface Treatment

A crucial component of implant dentistry is the topography of the dental implant surface. The texture of a dental implant surface can be modified in a variety of ways with the addition or removal of a material or chemical. Additive surface treatment occurs when a material or chemical is added to a dental implant to change the topography of the surface. Different surface textures can help increase the rate of healing and osseointegration and reduce the risk of dental implant failure. One example of additive surface treatment is acid-etching. An acid-etched implant has been treated with acid to change the implant topography and ideally improve retention of the implant once it is placed. What type of additive surface implant is used for a procedure depends on the patient’s unique needs, their bone quality in the area receiving the implant, and the preferences of the treating periodontist.
