Corrosion of Titanium Dental Implants : a Systematic Review of Literature
Objectives: The aim of this work is to determine the risks of corrosion of dental implants made of titanium and its alloys, the different forms of this corrosion and to establish a strategy to prevent this phenomenon. The answers to these questions were sought through a systematic review of the literature.
Methods: The search was conducted on MEDLINE, using Pubmed by three Boolean formulas:
1- ((("Titanium"[Mesh]) OR "titanium alloy (TiAl6V4)" [Supplementary Concept]) AND"Dental Implants"[Mesh]) AND "Corrosion"[Mesh]) AND prevention
2- ((("Titanium"[Mesh]) OR "titanium alloy (TiAl6V4)" [Supplementary Concept]) AND"Dental Implants"[Mesh]) AND "Corrosion"[Mesh]
3- ((("Titanium"[Mesh]) OR "titanium alloy (TiAl6V4)" [Supplementary Concept]) AND"Dental Implants"[Mesh]) AND "Corrosion"[Mesh]AND surface treatment
In addition, an ad hoc search was conducted on Google Scholar in order to make the study as exhaustive as possible.
Results: seventy-five articles were retained. 58 articles identified the corrosion of dental implants and its alloys,of which 48 articles mentioned the risk of electrochemical corrosion which manifested itself in different forms and 10 articles reported the risk of tribocorrosion, 17 articles reported the corrosion resistance of implants.
The factors triggering corrosion have been grouped into chemical factors, biological factors and mechanical factors. Clinical manifestations of corrosion were highlighted by 46% articles. These manifestations concern the loss of the implant, peri-implantitis, osteolysis, dental pain, fracture of the implant, allergy and also pigmentation of the gums. Different treatment methods have been elucidated whose resistance to corrosion has been demonstrated.
These treatments aimed at surface modifications by: surface coating, acid etching, anodic oxidation, modified sandblasting and porous titanium.
Conclusions: Knowing the factors involved in the corrosion of dental implants helps to establish treatments that improve corrosion resistance and optimize the osseointegration of implants.
