초록

목적: 본 후향적 연구의 목적은 의도적 재식술로 치료한 상하악 대구치의 단기간의 치료 결과를 평가하고자 하는 것이다. 환자 및 방법: 본 연구의 대상은 해부학적인 접근의 어려움 및 두꺼운 피질골 또는 하치조 신경, 상악동등과의 근접으로 인해 통상적인 치근단 수술이 불가능하거나 환자가 거부하는 경우 의도적 재식술을 시행한 35개의 상하악 대구치를 대상으로 하였다. 증례들의 경과 관찰 기간은 1년에서 2년 4개월이었다. 성공률은 임상적 성공과 방사선학적 성공을 기준으로 평가하였다. 결과: 의도적 재식술 과정중 발치 실패가 1증례(3%), 치주 질환 및 염증성 흡수로 발치한 경우가 2증례(6%)였고 구강내에서 기능하고 있으나 약간의 동요도와 치근의 흡수상이 관찰되는 경우가 3증례(9%)였고 특이한 이상없이 잘 유지되고 있는 경우는 29증례(82%)였다. 결론: 의도적 재식술은 접근성 및 해부학적인 구조등으로 인해 치근단 수술이 불가능한 경우 적절한 증례 선택과 숙련된 술자에 의해 시술이 이루어진다면 재현성 있고 예지성있는 치료가 될 수 있다.

Objectives: This retrospective study evaluated the therapeutic effects of the intentional replantation (IR) procedure performed on the maxillary and mandibular molars of 35 patients. Materials and Methods: For the subjects, IR was performed due to difficulties in anatomically accessing the lesions and/or close proximity to the thick cortical bone, inferior alveolar nerve, or maxillary sinus, which rendered the ordinary periradicular surgery impossible. The patients'progress was followed for a year and up to 2 years and 4 months. The success of the procedure was evaluated in terms of clinical and radiographic success (%). Results: The results revealed the following: (a) 1 case (3%) of failed tooth extraction during IR; (b) 2 cases (6%) of extraction due to periodontal diseases and inflammatory root resorption; (c) 3 cases (9%) of normally functioning teeth in the oral cavity with minor mobility and apical root resorption, and; (d) 29 cases (82%) of normally functioning teeth without obvious problems. Conclusions: IR was confirmed to be a reliably repeatable, predictable treatment option for those who cannot receive conventional periradicular surgery because of anatomic limitations or patient factors.
