Abstract

Implant fixed prosthesis for the complete edentulous maxilla provides significant benefits in the aspects of functions and esthetics compared with the conventional denture. Implant supported fixed prosthesis are totally supported by implant, and thus stabilizes the prosthesis to the maximum degree as possible. Also, the improved retention and stability of fixed prosthesis enhance patients' psychological and psychosocial health. This clinical presentation describes a maxillary full arch implant-supported fixed prosthesis in complete maxillary edentulous patient who showed vertical and horizontal alveolar bone resorption in the anterior ridge. To rehabilitate the esthetics and proper lip support, the zirconia framework was fabricated and the pink porcelain was veneered to reproduce the natural gingival tissue. After 9 months of follow up, the restorations were maintained without complications and the patient was satisfied with the restoration both functionally and esthetically.

상악무치악 환자에서 임플란트를 이용한 고정성 보철 수복 치료는 전통적인 가철성 의치에 비해 안정성과 유지력이 개선되어 저작, 발음 등의 기능적인 면과 환자의 심리적 안정성 및 만족도에서 이점을 갖는다. 본 증례에서 환자는 치주질환에 이환된 국소의치의 지대치를 모두 발거한 상악무치악 상태로, 7개의 임플란트를 식립하여 임플란트 지지 고정성 보철물로 수복하였다. 잔존 치조골의 흡수가 심한 전치부 골 결손부위에는 적절한 상순 지지를 얻기 위해 부피가 큰 지르코니아 하부구조물을 제작하였고, 치경부에 분홍색 도재를 축성하여 치은 연조직의 색조 및 외형을 재현하였다. 치료 후 9개월간의 임상 관찰에서 환자는 심미적, 기능적으로 만족하였고, 보철물은 합병증 없이 안정적으로 유지되었기에 이에 보고하고자 한다.
