Statement of problem: Crestal bone loss, a common problem associated with dental implant, has been attributed to excessive bone stresses. Design of implant's transgingival (TG) part may affect the crestal bone stresses. Purpose: To investigate if concavely designed geometry at a dental implant's TG ...

치과용임플란트의경부를둘러싸고있는조직 중, 연조직과 경조직은 어떤 손상을 받을 수 있는가? | 치과용임플란트의경부를둘러싸고있는조직은대단히 가혹한 조건에 노출된다. 이 부위의 연조직과 경조직은 임플란트 식립시 피판 거상 등 수술에 따른 조직손상,1,2 drilling에 의한 열손상3 등을 받을 수 있고, 구강환경의 생화학적 자극과 저작압에 따른 응력을 지탱하여야 한다. 외부자극이 생리적 허용치를 넘는 경우 조직의 퇴축이생길수있고, 임플란트지지골, 특히경부골의퇴축이 관리되지 않으면 장기적으로 임플란트의 실패로 이어질 수 있으므로 유의를 요한다. | |
임플란트경부골의퇴축원인에는 어떤 것들이 있다고 거론되는가? | 임플란트경부골의퇴축원인에대해서는아직학문적 논란이 진행되고 있다. 주요 인자로 거론되어온 것들에는 외과시술에 의한 손상, 1 과하중, 5 임플란트 주위염, 6 고 정체/지대주 연결부의 미세한 틈새, 6-8 생물학적 폭경, 9-11임플란트 경부의 디자인, 12 등이 포함된다. 구강조건에서는 여러 인자들이 중첩하여 작용하므로 각 인자들간의 상호관계를 정량적으로 규명하기 위해서는 아직 많은 노력이 필요할 것이다. | |
