Abstract

Severe cases of mandibular prognathism can be treated with orthodontic therapy or surgical correction, but there are situations where only prosthetic improvement is possible. An understanding of class III patients is needed, including a vertical chewing pattern and the absence of anterior guidance. Additionally, it is relatively easy to increase occlusal vertical dimension to correct the anterior crossbite, but this approach can sometimes lead to unfavorable results, necessitating careful diagnosis and treatment planning. In this case report, oral rehabilitation was conducted in a patient with mandibular prognathism and asymmetry, utilizing implants and fixed dental prosthesis. Through a step-by-step treatment approach, the existing occlusal vertical dimension was maintained, and the final fixed dental prosthesis restoration was completed. Accordingly, it shows functional and aesthetically appropriate results, and reports on the patient's diagnosis and treatment process.

심한 하악 전돌증이 있는 환자의 경우 교정치료나 악교정수술을 활용하여 치료를 시도할 수 있으나, 장기간의 교정치료 및 수술의 침습적인 거부감이 있는 환자에서 보철적으로만 개선해야 하는 상황이 존재할 수 있다. 골격성 III급 부정교합 환자는 전방유도가 없으며, 수직적인 저작 양식을 보여주기 때문에 이러한 측면을 고려하여 치료하는 것이 중요하다. 또한, 전치부의 반대교합을 개선하기 위한 방법으로 교합수직고경을 거상하는 술식을 선택하기 쉬운데, 이는 종종 불리한 결과를 야기할 수 있으므로 신중한 진단 및 치료계획의 수립이 필요하다. 본 증례에서는 하악 전돌 및 비대칭을 가진 환자에서 단계적인 치료과정을 통하여 기존의 교합수직고경을 그대로 유지하며 임플란트 및 자연치를 이용한 최종 고정성 보철 수복을 진행하였다. 이에 기능적이고 심미적으로 적절한 결과를 보여, 환자의 진단 및 치료 과정에 대해 보고하고자 한다.
