Full mouth rehabilitation of non-vertical stop occlusion with resilient telescope over-dentures and implants

Abstract

OHIP-14 The patient presented with a chief complaint of ill-fitting denture and masticatory disturbance by loss of the posterior occlusion. An intraoral observation found posterior occlusal support lost and the relation of the front teeth which originally was assumed to be the angle class III. The maxillary left anterior teeth, the abutment of the old denture, presented with mobility and plaque control was poor. Due to the patientʼs medical history of apical hypertrophic cardiomyopathy, the surgical invasion had to be minimized and a resilient telescope overdenture was designed preserving the remaining teeth. After confirming occlusal stability by treatment denture, the final prosthesis was fabricated based on the occlusion of the treatment denture. The score of OHIP-14, which evaluates QOL, improved and stabilized from 44 at the initial examination to a score of 13, but deteriorated to a score of 29 one year later. The implants placed in advance were employed in rescue, helping the score improve to 6. Currently, the dentures, the implants, and the abutment teeth are in stable condition, and the OHIP-14 score remains good, which contributes to the improvement of the patient's QOL.
