Abstract

Crossed occlusion can be treated either by overdenture and telescopic denture or by placing an implant at the edentulous area to reestablish the support on the occlusion. If alveolar bony support is sufficient and an the environment where an implant is inserted is favorable to restoring the masticatory and aesthetic function of a patient, the implant-supported fixed prosthesis can provide more definitive occlusal support and more aid for other oral functions. In this case report, a patient with a severe residual alveolar bone resorption following the extraction of teeth and who had a crossed occlusion was treated with sinus bone graft and alveolar bone augmentation in order to place the implants at prosthetically position. The definitive restoration was made to reflect the patient's occlusal and aesthetic function using the CAD/CAM double scanning method. Finally, the treatment had the masticatory and aesthetic function adequately restored, which is reported here.

엇갈린 교합 환자의 치료 방법은 피개의치, 이중관 의치를 사용하여 치료하거나 결손 부위에 임플란트를 식립함으로써 교합 지지를 회복해주는 방법이 있다. 잔존 치조골의 양이 양호하고 심미적, 기능적으로 임플란트 식립이 가능한 경우 임플란트 고정성 보철물 수복을 통해 환자에게 적절한 교합지지 및 기능, 편안함을 제공할 수 있다. 이 증례는 발치 후 심한 치조골 흡수가 동반되어 좌우 엇갈린 교합이 된 환자에서 상악동 골이식술 및 수직, 수평적 치조골 증대술을 실시하였다. 이후, 보철적으로 이상적 위치에 임플란트를 식립하였고 임시 보철물로 환자의 고유의 기능 및 심미를 평가한 후 이를 반영할 수 있는 double scanning technique을 사용하여 최종 보철물을 제작하였다. 이를 통해 엇갈린 교합을 성공적으로 극복하였으며, 저작 및 심미를 회복하여 만족스러운 결과를 얻었기에 이를 보고하고자 한다.
