THIS PHASE I RESEARCH AIMS TO DEVELOP AN ORTHODONTIC APPLIANCE THAT WILL APPLY A DETERMINED AMOUNT OF POTENTIAL ELASTOMERIC ENERGY TO MALOCCLUDED TEETH, BRINGING THEM TO A PREDETERMINED OCCLUSION THAT IS ACCEPTABLE WITH GNATHO- LOGICAL PRINCIPLES.

THIS PHASE I RESEARCH AIMS TO DEVELOP AN ORTHODONTIC APPLIANCE THAT WILL APPLY A DETERMINED AMOUNT OF POTENTIAL ELASTOMERIC ENERGY TO MALOCCLUDED TEETH, BRINGING THEM TO A PREDETERMINED OCCLUSION THAT IS ACCEPTABLE WITH GNATHO- LOGICAL PRINCIPLES. THE COMPLETE ORTHODONTIC POSITIONER ELASTIC (COPE) IS BASICALLY CLEAR, INCONSPICUOUS, AND REMOVABLE. DEVELOPMENT INTENDS TO DEMONSTRATE PERFORMANCE CAPABILITY THAT IS EFFECTIVE AND SIMPLER THAN THE PROGRESSION OF CONVENTIONAL ORTHODONTIC APPLIANCES. DURING PHASE I, RESEARCHERS WILL . STUDY SELECTED ELASTOMERS AND TEST AND EVALUATE THEIR CHARACTERISTICS . DEVELOP COPE-BORNEATTACHMENTS THAT ARE SECURELY BONDED TO THE BASE ELASTOMER AND WHICH WILL EFFECTIVELY GRASP TEETH TO TRANSFER FORCE . DEVISE A TECHNIQUE TO DIRECTLY MEASURE APPLIED FORCES WITHWITH MINIFORCE TRANSDUCERS AND CONVENTIONAL SOLID-STATE ELECTRONICS . DETERMINE COPE'S RANGE OF TOOTH MOVEMENT, IN VITRO, UNDER SELECTED MALOCCLUSION CONDITIONS. PHASE II EFFORTS, BASED ON PHASE I RESULTS, WILL INCLUDE IN VIVO TESTS CATEGORIZING COPE CAPABILITY, PATIENT COOPERATION, ANDCOMFORT AND IN VIVO MEASUREMENT OF APPLIED FORCES. PHASE IIWILL ALSO EXAMINE COPE POTENTIAL AND ORTHODONTIST AND PATIENT ACCEPTANCE.
