Abstract

When a maxillary implant-supported fixed prosthesis is planned for anterior partially edentulous region, the degree of atrophy of the residual ridge, prospective location of the implants and inclination of the implant axis, soft tissue volume dimensions, esthetics, and phonetics of the patient should be considered. The signs of osteoarthritis and deviation in form on the left condyle head were found in the temporomandibular joint radiogram of the patient reported herein due to her habit of unilateral chewing for 20 years. Furthermore, the patient had loss of left mandibular posterior teeth, an unequal occlusal plane, extruded and rotated mandibular anterior teeth, a high smile line, and high expectations. This report describes the treatment procedure for establishing occlusal plane, physiologic occlusion with stabilized posterior tooth contact and anterior guidance, and equilibration in centric relation-maximum intercuspation discrepancy using zirconia restorations with a computer-aided design/computer-aided manufacturing system in an adapted centric posture.
