Adult treatment is often hindered by the psychological, periodontal, articular and/or muscular context. Denture is often incomplete, and malocclusion is more varied.
Analysis of orthodontic mechanics is thus essential to reduce unwanted displacements and achieve treatment objectives. Mini-screws are often very useful here, ensuring rigid anchorage and enhancing treatment efficacy.
Benefit is discussed, based on two case reports: one using a slide mechanism and the other a frictionless mechanism.
Key words: Biomechanics / mini-screw / adult treatment / friction
