Relationship between patient discomfort, appliance acceptance and compliance in orthodontic therapy.

Abstract

Orthodontic treatment is occasionally a discomfort to patients, due to pain or functional restrictions. In this context, several retrospectively planned studies were performed in the 1980s, but correlations between different aspects of patient discomfort were not investigated. The present study aimed at examining and structuring the psychogenic dimensions of patient discomfort. Furthermore, the impact of the patient's attitude on the intensity of discomfort was to be evaluated in addition to the influences of appliance therapy. The study was performed with 67 patients aged from 9 to 32 years. Prior to insertion of a new appliance, psychogenic scales reflecting their attitude towards orthodontic therapy were submitted to them. They were instructed to keep a discomfort log during the first 7 days after insertion. After 6 months they were given lists for retrospective assessment of discomfort and an appliance-acceptance scale to be filled in. At the same time, the respective orthodontist assessed his patient's compliance on a cooperation scale. The factor analysis revealed 3 levels of patient discomfort: feelings of tension, functional restrictions and aversion to wearing an orthodontic appliance in public. Appliance acceptance after 6 months could be predicted from the attitude towards treatment and the experienced discomfort. Patient compliance also correlated with these factors, so that causal flow diagrams of the investigated variables could be produced. Giving detailed information on any discomfort occurring and explaining how to reduce or eliminate it are vital factors in good treatment cooperation.
