A comparison of treatment impacts between Invisalign aligner and fixed appliance therapy during the first week of treatment

Objective: To compare patients' perceptions of fixed and removable appliance therapy for correction of anterior crossbite in the mixed dentition, with special reference to perceived pain, discomfort, and impairment of jaw function. Materials and Methods: Sixty-two patients with anterior crossbite and functional shift were recruited consecutively and randomized for treatment with fixed appliances (brackets and archwires) or removable appliances (acrylic plates and protruding springs). A questionnaire, previously found to be valid and reliable, was used for evaluation at the following time points: before appliance insertion, on the evening of the day of insertion, every day/evening for 7 days after insertion, and at the first and second scheduled appointments (after 4 and 8 weeks, respectively). Results: Pain and discomfort intensity were higher for the first 3 days for the fixed appliance. Pain and discomfort scores overall peaked on day 2. Adverse effects on school and leisure activities were reported more frequently in the removable than in the fixed appliance group. The fixed appliance group reported more difficulty eating different kinds of hard and soft food, while the removable appliance group experienced more speech difficulties. No significant intergroup difference was found for self-estimated disturbance of appearance between the appliances. Conclusions: The general levels of pain and discomfort were low to moderate in both groups. There were some statistically significant differences between the groups, but these were only minor and with minor clinical relevance. As both appliances were generally well accepted by the patients, either fixed or removable appliance therapy can be recommended. (Angle Orthod. 2016;86:324-330.)

A randomized controlled trial of self-perceived pain, discomfort, and impairment of jaw function in children undergoing orthodontic treatment with fixed or removable appliances

“…The weakest (although significant) correlation was seen between pain and discomfort the first week with braces and treatment satisfaction, which is interesting because there is general agreement that the level of pain is highest on days 2 through 4 after bonding. [16][17][18] Because almost all patients wore a thermoplastic retainer (Raintree Essix, Los Angeles, Calif) as a retention device in the upper jaw, it is logical that the patients experienced some pain and discomfort. This type of retention is semielastic and can therefore cause tension on newly debonded teeth, which could explain the effect on treatment satisfaction.…”

“…However, the type of appliance did have an effect on impaired speech and swallowing. 19 Miller et al 20 carried out a comparison of treatment impacts between Invisalign2 aligners and fixed appliance therapy during the first week of treatment and found that adults treated with Invisalign2 aligners experienced less pain and fewer negative impacts on their lives during the first week of orthodontic treatment than did those treated with fixed appliances. 20 Thus, the type of appliance might affect some aspects of OHRQoL, but the relationship is not as yet clear.…”
