Adult orthodontic retreatment: A survey of patient profiles and original treatment failings

Differences in nickel ions released from nickel-titanium arch wire after immersion in detergent and non-detergent toothpaste

“…As a result, more metal ions undergo oxidation which speeds up the corrosion pro cess, resulting in the release of nickel ions. 1,4,[22][23][24] NiTi arch wire has a titanium element which will form a thin passive layer in the form of a layer of TiO2 on the wire surface. This passive layer serves to protect NiTi arch wire from corrosion process, but if there is a damage to the passive layer it will cause the release of nickel ions on the surface (especially TiO2) of NiTi arch wire.…”

“…Orthodontic treatment in adult is growing steadily in the last 3 decades. 1 In the United States, orthodontic treatment in adult was reported to increase from 15.4% to 21.0% between 1981 and 2017. 1 In 2018, a survey done by the British Orthodontic Society showed that members treated 5% more adult patients in the private clinic than in 2016.…”

Orthodontic retention and the role of the general dental practitioner

“…A similar, though less convincing, trend was also seen in a follow-up study focusing on upper incisal irregularity. 6 Chow et al (2020) 7 investigated factors that may have led to relapse in patients who were seeking re-treatment, comparing the original malocclusion to their relapsed state. The factors that were thought to contribute to relapse once again included poor original treatment, maturational changes, unfavourable growth and inadequate retention.…”
