Bioactive Fixation

Bioactive fixation refers to stabilization involving direct physical and/or chemical attachment mechanism(s) between biological tissues and a dental implant surface at the ultra-structural level. Materials such as zirconia are often used in dental implants, however, they can require surface treatment in order to stimulate osseointegration. Studies have shown that the creation of a nano-porous surface on such materials allows for the chemical coating of different bioactive substances which has led to increased implant osseointegration and fixation. Other materials used are directly bioactive meaning they require no additional treatments for the enhancement of fixation. These include bioactive glass which has the capacity to bond with soft and hard tissues for stable fixation. In addition, bioactive glass is biocompatible, strong but lightweight, and can be used as a support structure as long as needed. The use of bioactive materials for fixation of dental implants can lead to increased stability, attachment, and success of the implant.
