Abstract

Mandible defects could be caused by congenital malformations, trauma, osteomyelitis, tumor resection. If large areas are included for reconstruction, those are primarily due to tumor resection defects. The large jaw defect results in a problem about mastication, swallowing, occlusion and phonetics, and poor esthetics causes a lot of inconvenience in daily life. It is almost impossible to be a part underwent mandibular resection completely reproduced, should be rebuilt artificially. This case is of a patient who was diagnosed with squamous cell carcinoma pT1N0M0, stage I in February 2004 and received surgery (combined mandibulectomy and neck dissection operation (COMMANDO) in oromaxillofacial surgery) in March 2004, by implant assisted removable partial denture. We could obtain good retention and stability through sufficient coverage and implant holding. Follow up period was about four years. Mandibular left third molar regions have been observed to have resorption of surrounding bone, and periodic check-ups are necessary conditions.

하악골의 결손은 선천적 기형, 외상, 골수염, 종양 절제술 등에 의하여 초래될 수 있는데, 이중 결손부위가 큰 경우는 주로 종양절제술에 의한 결손이다. 악골 결손 부위가 커질수록 저작, 연하, 교합, 발음 등에 큰 지장을 초래하게 되며 심미적으로도 불량하여 일상생활에 많은 불편을 주게 된다. 하악골이 절제된 후 그 자리에 완전히 재생되는 경우는 희박하며 인공적으로 재건해 주어야 한다 일반적으로 자가골 이식을 이용한 재건술을 시행하며, 통상적인 부분의치 혹은 총의치를 시행하거나, 지지할 수 있는 골을 얻은 상태에서 임플란트 고정성 보철, 임플란트 보조 국소의치 혹은 피개의치 등을 시행할 수 있다. 본 증례는 2004년 2월 25일, 편평세포암종 pT1N0M0, stage I로 진단 받고 구강악안면외과에서 동년 3월, 하악 좌측 부위 COMMANDO 수술(combined mandibulectomy and neck dissection operation), 광범위 절제술(wide excision), 하악골 변연절제술(marginal mandibulectomy), 견갑 설골 상부 경부청소술(supraomohyoid neck dissection, SOHND), 시행받은 환자를 하악 좌측 중절치, 하악 좌측 제3대구치 부위에 임플란트 식립하여 임플란트 보조 국소의치로 수복하였고 충분한 피개와 임플란트로의 적절한 교합력 분산을 통해 통상적인 국소의치보다 더 이로운 지지, 유지, 안정을 얻을 수 있었다. 현재까지 경과 관찰 기간은 4년 정도 되었으며, 하악 좌측 제3대구치 부위에는 주위골의 흡수양상이 관찰되어 주기적인 검진이 필요한 상황이다.
