Abstract

After tooth extraction, alveolar bone is resorbed over time. Loss of alveolar bone and reduction of upper soft tissue poses difficulties in future implant placement and long-term survival of the implant. This case report focuses on increasing the soft and hard tissues at the implant placement site by using alveolar ridge augmentation and a xenogeneic collagen matrix as a soft tissue substitute in an extraction socket affected by periodontal disease. In each case, the width of the alveolar bone increased to 6 mm, 8 mm, and 4 mm, and regeneration of the interdental papilla around the implant was shown, as well as buccal keratinized gingiva of 4 mm, 6 mm, and 4 mm, respectively. Enlarged alveolar bone facilitates implant surgery, and interdental papillae and keratinized gingiva enable aesthetic prosthesis. This study performed alveolar ridge augmentation on patients with extraction sockets affected by periodontal disease and additionally used soft tissue substitutes to provide a better environment for implant placement and have positive effects for aesthetic and predictive implant surgery.

발치 후 시간이 지남에 따라 치조골이 흡수되는 것은 자연스러운 현상이다. 치조골 소실과 상부 연조직의 감소는 추후 임플란트 식립 및 임플란트의 장기 생존 가능성에 어려움을 준다. 이번 증례보고는 치주질환에 이환된 발치와에 치조제 증강술과 연조직 대체제 중 이종 콜라겐 기질을 함께 이용하여 임플란트 식립 부위의 연조직과 경조직을 증가시키는 데 중점을 둔다. 각각의 증례에서 치조골의 너비가 6 mm, 8 mm, 4 mm로 증가하였고, 임플란트 주변으로 치간 유두의 재생과 각각 4 mm, 6 mm, 4 mm의 협측 각화치은을 보여준다. 증대된 치조골은 임플란트 수술을 용이하게 하며 치간 유두와 각화치은은 심미적인 보철이 가능하게 한다. 이 연구는 치주질환이 이환된 발치와를 가진 환자에게 치조제 증강술을 시행하고 연조직 대체제를 추가로 사용함으로써 임플란트 식립을 위한 보다 나은 환경을 제공하고 심미적이고 예지성 있는 임플란트 수술을 위한 긍정적인 효과를 보여준다.
