Abstract

In the mandibular posterior molar area, ridge deficiency is an unfortunate obstacle in the field of implant dentistry. Many techniques are available to rebuild the deficient ridge. Selection and necessity of these techniques are associated with significant morbidity and often require a second surgical site. With the advent of guided bone regeneration (GBR), one may now graft the deficient ridge with decreased morbidity and without a second surgical site. In this case, guided bone regeneration procedures were performed with a combination of allograft, xenograft, and alloplast, excepting autogerous bone at severe defected mandibular alveolar ridge and then placed to the implant successfully. We report that implant placement were good in two cases.

하악 구치부에 있어서 치조제 결손은 임플란트 치과학에 있어서 큰 장애물이라 할 수 있다. 이러한 치조제를 재건하는데 있어서 여러 가지 술식이 활용되고 있다. 술식들의 선택 및 필요성은 현저한 질병의 이환률과 관련이 있으며, 2차적인 수술 부위를 요구하는 경우도 있다. 골 유도 재생술(GBR, guided bone generation)의 발전은 결손이 존재하는 치조제의 이환률을 낮추며, 2차적인 수술 부위를 요구하지 않는 경우로 볼 수 있다. 본 증례에서는 심하게 결손된 하악 치조골에 자가골을 제외한 동종골, 이종골, 합성골 입자형 골이식재를 조합하여 골 유도 재생술(GBR)을 진행한 후에 임플란트를 성공적으로 식립을 하였다. 두 증례에서 양호한 식립을 보였음에 보고하는 바이다.
