초록

This report presents two cases concerning strategies for improving denture retention in pediatric patients with oligodontia caused by hypohidrotic ectodermal dysplasia (HED). Both patients presented with multiple missing teeth, conical canines, alveolar bone atrophy, and a skeletal Class III tendency. In the first case, a modified form of conical-crown-retained denture was used to cover the canines. This approach was carried out without tooth extraction or coping. In the second case of severe alveolar bone resorption and a distally tilted lower left canine, the tooth was restored with a hybrid ceramic crown. It was subsequently converted into a clasp-retained removable partial denture, utilizing a suction mechanism. Both patients are currently receiving regular check-ups for the maintenance of their prosthetic appliances and the evaluation of their growth patterns. This study presents innovative prosthetic treatment methods for pediatric patients with HED who have inadequate denture retention.

이 논문은 저한성 외배엽 이형성증(Hypohidrotic Ectodermal Dysplasia, HED)으로 인한 부분무치증을 가진 소아 환자에게 의치의 유지력 증가 방법에 관한 두 가지 증례를 보고한다. 두 환자 모두 다수의 치아 결손 및 원추형의 견치와 치조골 위축, 골격적 III급 경향이 나타났다. 첫 번째 증례에서는, 변형된 형태의 Conical-Crown Retained Denture (CCRD)를 이용해 견치를 피개하였다. 이 방법은 치아를 삭제하거나 코핑 없이 진행되었다. 두 번째 증례에서는, 심한 치조제 흡수와 함께 하악 좌측 견치가 원심으로 경사지어 맹출한 상황에서, 하이브리드 세라믹 크라운을 사용하여 견치를 수복한 후, 흡착성 원리를 이용한 클라스프 유지 가철식 의치로 변경하였다. 두 환자는 현재 보철물 유지 관리 및 성장양상을 평가하기 위해 주기적으로 치료를 받고 있다. 이 증례는 HED로 인하여 의치의 유지력이 부족한 소아 환자에게 적용된 창의적인 보철 치료 방법을 제시하였다.
