Compliance to delivery of orthodontic appliances within specified times and factors which influenced compliance by dental technicians in Selangor was evaluated. This is a prospective 8-month study of 18 trainee/ trained technicians from 4 main government dental laboratories in Kajang, Klang, Tanjong Karang and Shah Alam. Delivery times specified by orthodontists were 1 day for plastic retainer, 3 days acrylic retainer, 5 days active plates (URA), 10 days functional appliances (FA), 10 days transpalatal arch (TPA) and 10 days for quadhelix. Punctual delivery was recorded as ‘compliant’. Compliance was compared between appliances, clinics, technicians, orthodontists and seniority of technicians. The sample comprised appliances from 365 patients; 38 (10.4%) Tanjong.Karang, 114 (31.2%) Kajang, 191 (52.3%) Klang and 22 (6.0%) Shah Alam. The majority of appliances were retainers (66.3%), followed by URA (13.4%), functionals (9.3%), TPA (9.0%) and quadhelix (1.9%). Mean compliance for all appliances in Selangor was 55%. Plastic retainers had highest compliance (77.8%), followed by acrylic retainers (59.9%), quadhelix (57.1%), FA (47.1%), TPA (45.5%) and URA (24.5%). Senior technicians (>3 years in service) were more compliant than juniors (
