Prosthetic rehabilitation of pseudo-Class III malocclusion using tooth- and implant-supported prosthetic restoration in centric relation (CR): a case report

This report presents the management of a patient with pseudo Class III malocclusion and unstable mandibular movements caused by the lack of a stable occlusal stop.Without posterior support, the mandibular incisors slid along the labial surfaces of the maxillary incisors during centric relation (CR) guidance, resulting in anterior mandibular closure.This pattern presented as a habitual anterosuperior mandibular displacement during voluntary closure.Provisional prostheses for the maxillary anterior teeth and mandibular posterior implants were concurrently positioned in the appropriate CR position.Following the immediate establishment of a stable stop for proper CR, stable mastication in this position was achieved.The findings suggest that the patients with unstable CR guidance due to insufficient occlusal stabilization can attain immediate functional stability through a reliable teeth stop in the corrected CR position.(
