Abstract

Orthodontic miniscrews are temporary anchoring devices that help as adjuvants in orthodontic treatment and whose use has increased in recent times. Miniscrew failures can happen during the first week of insertion, so improving stability is an important step to enhance treatment reliability. A possible solution to this issue is to modify the miniscrew surface.
Objective:
To identify in the current literature the most widely used surface treatments that favor the primary and secondary stability and success of orthodontic miniscrews.
Material and method:
A search was made in Pubmed and EBSCO with the English terms “miniscrew”/”mini implant” AND “surface”, “treatment” and “stability”. In vivo studies were included with the aim of comparing and/or evaluating the effect of the treatments performed on the miniscrew’s surface and their success or stability, articles available in English and Spanish. Studies performed in dental and/or medical implants, in vitro, clinical studies without control group were excluded.
Results:
25 publications were used in the review, with 11 types of surface treatment studied. The generation of titanium oxide nanotube matrices, ultraviolet-mediated photofunctionalization and surface anodizing showed an increase in the stability of the miniscrews. The use of conventional techniques: acid etching, sandblasting-acid etching, is inconclusive as to its effect on stability.
Conclusion:
There is little evidence of surface treatments performed on orthodontic miniscrews to improve their stability. Pioneering techniques such as the generation of titanium oxide nanotube matrices, ultraviolet-mediated photofunctionalization and surface anodizing showed increased stability of the miniscrews, and require their replication on human studies. The use of conventional techniques such as acid etching and acid sandblasting-etching is inconclusive as to its effect on the stability of the miniscrews.
