Abstract

Surgical management of oral cancer results in compromised masticatory and swallowing function which affects patient in social and psychological aspects due to reduced phonetic ability and facial deformity, thus, it is imperative to provide applicable prosthetic treatment to overcome such complications. This clinical study describes rehabilitation of a patient with squamous cell carcinoma treated with marginal mandibulectomy and implantation on preserved posterior portion of mandible to provide stability and support for subsequent denture treatment. Kennedy class IV removable partial denture has provided satisfactory results in esthetics and function. Bone level stability around implants was reported to be maintained during eight months of clinical observation.

구강암에 의해 하악골 절제술을 받은 환자들은 저작 및 연하 기능의 저하와 같은 문제가 발생하며 동반된 안모의 변화와 발음의 문제로 인하여 사회적, 심리적인 영향을 받게 된다. 따라서 보철적인 수복을 통해 하악골 변연절제술 환자의 문제를 개선해 나아가는 것이 무엇보다 중요하다. 본 증례는 편평세포암으로 인하여 하악골 변연절제술을 받은 환자에서 골결손이 일어나지 않은 후방부위에 전략적으로 임플란트를 식립하였고 임플란트를 통해 의치의 유지와 지지를 담당할 수 있도록 보철물을 설계하였다. 이를 바탕으로 Kennedy class IV 국소의치를 제작하여 만족스런 심미적, 기능적 결과를 얻었으며, 8개월 간의 임상 관찰 동안 임플란트 주변 골의 안정적인 유지가 관찰되는 바 이를 보고하고자 한다.
