Factors Affecting DecisionMaking For Congenitally Missing Permanent Maxillary Lateral Incisors: A Retrospective Study

Abstract

Implant-supported overdenture is a well-established treatment option for many patients who have functional problems with conventional dentures. It may be primary choice for patients with altered jaw anatomy, neuromuscular disorders, pronounced gag reflex, severe residual ridge resorption and oral tissue defects. In this article we describe a case report, where tongue cancer patients occlusion was rehabilitated with an implantretained overdenture. In 2001 patient was operated for squamous cell carcinoma on the left side of the tongue. Before preoperative radiation therapy, small residual mandibular dentition was removed because of its poor prognosis. Radiation dose on mandible was 57-66 Gy. After tumor surgery patient received conventional complete dentures. Ten
years later, the patient was referred again to the Turku University Central Hospital due to constant ulceration under the mandibular denture. The residual ridge of the mandible was severely resorbed. Patient’s existing lower complete denture was replaced with a milled bar-retained overdenture on four implants. Treatment turned out to be challenging due to severely restricted tongue movement and tissue defects.
