Abstract:

This case report focused on a patient with supraeruption of the first and second mandibular molars as a result of loss of the first and second maxillary molars for a long time. We adopted a combination of a vacuum-formed removable appliance and elastics to intrude the first and second mandibular molars by using a continuous, light force to acquire sufficient restoration space for maxillary molars. Thus, the dental-implant treatment was successful, and a good and stable occlusal relationship was established.

Key words: molar intrusion, removable appliance, dental implant treatment
