Abstract

To enhance the predictability of aesthetic treatment outcomes in aesthetic prosthetic restorations, considerations must include analysis of facial features, the relationship between teeth and lips, proportions of tooth width/length, gingival form, and more. Traditional diagnostic wax-ups have limitations in considering the patient's facial features and are unable to facilitate rapid form modifications. With recent advancements in digital technology, it is now possible to digitize the patient's facial features in three dimensions, enabling the design of restorations that harmonize with facial features. These digital workflows not only improve efficiency but also provide patients with faster visualization of treatment outcomes, thereby enhancing motivation. Therefore, in this case, a treatment plan is devised to utilize digital diagnostic wax-ups considering the patient's facial features for the final prosthetic design.

심미 보철 수복에서 심미적인 치료 결과의 예지성을 높이기 위해서는 안모 분석과 치아와 입술과의 관계, 치아의 형태 너비/길이 비율, 치은의 형태 등을 고려해야 한다. 기존에 사용되는 전통적인 진단 왁스업은 환자의 안모를 고려할 수 없으며, 빠른 형태 수정이 불가하다는 한계가 있다. 최근에는 디지털 기술을 이용하여 환자의 안모를 3차원화한 가상 환자를 제작하여 안모와 조화되는 수복물을 디자인할 수 있게 되었다. 이러한 디지털 작업은 효율적일 뿐만 아니라 환자에게 빠르게 시각화된 치료 결과를 제시하여 동기 부여의 효과를 줄 수 있다. 따라서 본 증례는 환자의 안모를 고려한 디지털 진단 왁스업을 통해 심미적인 전치부 보철 수복을 시행하였다.
