In this blog Aljeeta Kadam looks at a review of adjuncts or alternatives to mechanical retention in preserving post orthodontic treatment outcomes. Only 7 studies were included in the review providing very low quality evidence about the use of adjuncts and alternatives.

This review of canine retraction after maxillary first premolar extraction in adolescent and adult orthodontic patients using fixed appliances included 50 RCTs. However only a small number of studies contributed to the estimate of 4.98 months (95%CI; 2.92 to 12.88 months) to complete canine retraction.

This review of the effects of micro-osteoperforation on the rate of tooth movement in patients undergoing orthodontic treatment included 6 RCTs. Although meta-analysis found a small statistical benefit in favour of micro-osteoperforation in the short term the clinical benefits particularly over the duration of a course of treatment remain unclear.

14 studies ( 6 RCTs) were included in this review of corticotomy for facilitating orthodontic treatment. While the results found produce statistically and clinically meaningful temporary increases in the rate of orthodontic tooth movement the studies were small and of low quality.

This Cochrane review only identified 4 small short-term trials providing limited evidence for the effectiveness of surgical approaches to accelerate orthodontic treatment. Further research with longer follow up is needed to confirm any possible benefit.

With typical orthodontic treatment taking 18-24 months there is pressure to reduce the time it takes. This review considers a range of potential options but there is limited quality evidence for most of the techniques identified.

In treating orthodontic problems in late adolescents and adults there is pressure to shorten treatment time. Surgical techniques such as corticotomy and dental distraction have been proposed as potential approaches. The aim of this review was to address 3 questions; Does surgically facilitated orthodontic treatment significantly increase the velocity of tooth movement and shorten treatment [read the full story…]
