Functional appliance therapy is frequently indicated in the mixed dentition to restore normal function and to correct skeletal discrepencies. Twin block is the most widely used functional appliance, with excellent clinical results and very good clinical compliance.
It consists of a maxillary and mandibular bite blocks at an incline and is designed for full time wear. We have devised a simple procedure to overcome this problem. By adding modeling wax or dental stone over the occlusal surface of an erupting tooth before acrylisation of the twin block will solve the problem.
