There are orthodontic closure, surgincal closure, prosthetic solution in the treatment of diastema. The orthodontic closure has been widely used owing to its conservative nature, but retention after treatment has been difficult and problematic. So, authors observed relapse and retention after the orthodontic closure of 3 diastema cases. The results might be summarized as follows : The space that had been approximated between central incisors, was reopened by the use of retention appliance which did not join two central incisors together though fixed prothesis. By the frenectomy, circumferential supracrestal fibrotomy and lingual bonded retainer which joined two central incisors together after the orthodontic closure of diastema, were good results obtained. The frenectomy, fibrotomy, and the fixed retention appliance which joined two central incisors together must be needed after the orthodontic closure of diastema.
