Abstract
Patients: She was 43 years old at the time of her first visit. She requested to replace metal teeth with ceramics. Her facial appear-ance showed lip incompetence, intraoral examination revealed an open bite between canine teeth, mild crowding, numerous prosthetic devices on the molars and unstable intercuspal position. Based on the cephalometric findings, a mild skeletal Class II
open bite due to retroversion of the mandible was diagnosed. After adjusting the occlusion to the position where the canine teeth occlude, orthodontic treatment of the mandibular anterior teeth and restorative treatment such as non-prep veneers on the maxillary lateral incisors were performed. Four years later, the composite resin on the canine incisor had been lost and was
replaced with veneer tips. Four years later, the occlusion is stable.
Discussion: Slight counterclockwise rotation of the mandible was observed and lip closure was achieved.
Conclusion: Traces of abrasion were indicative of the height of the occlusion. Non-prep veneers may be effective in improving the esthetics and anterior coupling in the case of mild open bite and plexus.
