Abstract

Discontinued and abandoned cases are an undesirable outcome of orthodontic treatment. The first of this 2-part series will detail the different factors that play a role in this phenomenon. The second paper will describe a study that attempts to identify specific factors that are implicated in discontinued treatment within a specialist orthodontic practice.

CPD/Clinical Relevance: Discontinued treatment is an unwelcome aspect of orthodontic practice. By having a better understanding of the factors that may be relevant, clinicians can be more careful in their selection and management of patients.

Article

Orthodontic treatment, in common with other medical interventions, carries with it a number of potential negative consequences which must be balanced against the benefits that treatment offers. Discontinued and abandoned cases are those that are terminated prematurely, before the intended outcome of treatment has been achieved. Discontinuation rates (DR) of up to 40% have been previously reported,1 but in the UK they generally range from 8–14% (Table 1). A study of UK-based orthodontic consultants showed a DR of 9.2%,2 with a more recent audit of early debonded cases reporting a DR of 11.2%.3 Older papers on NHS services show DRs of between 12% and 20%.4,5 NHS general and community services have shown DRs of 13.1% and 12.5%, respectively.6 Outside the UK, Swedish papers report DRs of between 4% and 15%;7,8 German studies show DRs ranging from 10–20%.9,10
