of ER―a was already observed on day 0 and increased slightly during bone formation whereas ER―b was hardly detected throughout this process. After osteoclasts appeared on the medullary bone surface, this type of bone disappeared from the bone marrow cavity (days 7∼15). ER―a expression simultaneously decreased slightly and ER―b levels remained very low. These results suggest that estrogen activity mediated by ER―a not only affects medullary bone formation but also bone resorption. -

distoapical third of the distal roots. However, there was no significant difference in the amount of root resorption between the two experimental groups. The control group did not exhibit any active root resorption lacunae. Conclusions: Periapical root resorption was induced by continuous extrusive tipping force and occlusal interference in rat mandibular molars. These data suggest that we orthodontists had better take care not to induce occlusal interference during our orthodontic treatment. -

치과 임플란트는 완전 무치악, 부분 무치악, 단일 치아 결손 환자 들의 보철 수복물로 널리 사용되고 있다. 비록 임플란트의 초기 성공 률이 90% 이상으로 대단히 높게 보고되고 있지만 사용 중에 임플란 트의 실패 및 파절이 발생되기도 한다1,2). 5년간의 임상적 연구에서 임플란트의 파절률은 0.2∼3.5%로 비교적 낮게 나타나고 있으나 15년 동안의 장기간 추적 연구에서는 기능하는 기간이 길어짐에 따 라 임플란트의 파절률이 증가되는 경향이 보고되었다. -

한국은 2019년에는 65세 이상 노인인구가 전체 인구의 14%로 예상 되는 고령화 속도가 가장 빠른 나라 중의 하나이다. 2006년 국민구강건 강 실태조사결과에 따르면 65∼74세 노인의 현존 영구치아 수가 1995 년 16.9개, 2000년 16.3개, 2003년 12.1개, 2006년 17.2개로 나타나 건강한 삶을 위해 필요한 20개에 미달하였으며, 65~74세 노인의 20개 이상 치아보유율도 2000년 46.9%, 2006년 49.5%로 절반에 못 미치는 것으로 조사되었다1). 즉, 노인의 현존 영구치아 수는 증가했지만 저작불편감을 느끼는 노 인의 비율은 크게 증가하는... -

implants2). Wilson et al. stated that the use of barrier membrane is not necessary if the distance between the implant surface and surrounding bone walls is below 1.5 mm3). Although, this protocol has obvious advantages, immediate implant installation may not prevent post-extraction site from remodeling process. According to Araujo et al4), in the animal test, the placement of an implant in the fresh extraction site failed to prevent the re-modeling that occurred in the walls of the socket. -

임플란트학의 주요 관심사가 임플란트의 식립이나 보철치료에서 임플란트의 유지관리로 변화함에 따라 최근 임플란트 주위염 (peri-implantitis)이 임상가들 사이의 화두로 떠오르고 있다1). 임플 란트에서는 치아에서 발생하는 치주염과 같은 염증성 질환이 발생하 지 않을 것이라는 근거 없는 기대들을 비웃기라도 하듯이 수많은 연구 들이 임플란트 주위 점막염(peri-implant mucositis)과 임플란트 주위염에 대한 보고들을 하루가 다르게 쏟아 내고 있다. 지금까지 밝혀 진 바에 따르면, 임플란트 주위염은 일종의 세균성...
