  • 통상적인 임플란트 치료는 식립 후 약 3 - 5개월 뒤 임플란트 상부 보철물을 제작한다. 이러한 치료과정의 단점으로는 환자가 임플란트 식립 후 보철물이 장착되는 최종 치료 시점까지의 기간 동안 유지력과 저작능력이 떨어지는 임시의 치를 사용하여 생활해야 한다는 것이다. 최근의 임플란트 식립 후 즉시 부하 보철물 치료는 시술 적응증에 따른 제한이 있긴 하지만, 잦은 치과 방문이 어렵고 진료에 대한 협조도가 낮은 정신적, 신체적 장애 환자들에게 더욱 유용하다고 생각된다. 본 증례에서는 삼차원 컴퓨터 유도 수술법을 이용한 임플란트 식립 후 즉시 부하 보철치료를 정신지체장애 환자에서 시행하였으며, 시술 후 좋은 경과를 보였기에 이를 보고하는 바이다.

  • Objectives: This study was performed to evaluate patterns of failure time after insertion, failure rate according to loading time after insertion, and the patterns of failure after loading. Materials and Methods: A total of 331 mini-implants were classified into the non-failure group (NFG) and failure group (FG), which was divided into failed group before loading (FGB) and failed group after loading (FGA). Orthodontic force was applied to both the NFG and FGA. Failed mini-implants after insertion, ratio of FGA to NFG according to loading time after insertion, and failed mini-implants according to failed time after loading were analyzed. Results: Percentages of failed mini-implants after insertion were 15.79%, 36.84%, 12.28%, and 10.53% at 4, 8, 12, and 16 weeks, respectively. Mini-implant failure demonstrated a peak from 4 to 5 weeks after insertion. The failure rates according to loading time after insertion were 13.56%, 8.97%, 11.32%, and 5.00% at 4, 8, 12, and 16 weeks, respectively. Percentages of failed mini-implants after loading were 13.79%, 24.14%, 20.69%, and 6.9% at 4, 8, 12, and 16 weeks, respectively. Conclusion: Mini-implant stability is typically acquired 12 to 16 weeks after insertion, and immediate loading can cause failure of the mini-implant. Failure after loading was observed during the first 12 weeks.

  • 치조골의 흡수와 치주조직의 염증을 동반한 심한 치주질환 환자에서 임플란트를 통한 구강 회복은 임상적으로 어려움이 있다. 하지만 골 형태에 따른 적절한 임플란트 식립 위치를 선정한다면 불필요한 골 이식이나 연조직 수술을 최소로 할 수 있다. 최근에는 cone beam CT 촬영과 소프트웨어를 이용하여 환자의 해부학적 형태와 보철적인 위치를 고려하여 임플란트 식립 위치를 선정할 수 있게 되었고 3D printing 기술을 통해 제작된 surgical guide를 통해 계획된 위치로 정확한 수술이 가능하게 되었다. 본 증례는 70세 여성 환자로 심한 치주질환으로 인해 전악 치아의 발치가 필요하였으며 임플란트 지지 고정성 보철물로 전악 구강회복을 시행하였다. 수술 시에는 보철적인 위치를 고려한 surgical guide를 이용해 flapless 방식으로 임플란트를 식립하였고 수술 전에 CAD/CAM 방식으로 제작된 임시보철물을 즉시 부하하였다. 이후 맞춤형 지대주와 지르코니아를 이용한 보철물을 제작하였으며, 만족스러운 심미 및 기능 회복을 보였기에 보고하는 바이다.

  • Purpose: This study evaluated the associations of the dental arch form, age-sex groups, and sagittal root position (SRP) with alveolar bone thickness of the maxillary central incisors using cone-beam computed tomography (CBCT) images. Materials and Methods: CBCT images of 280 patients were categorized based on the dental arch form and age-sex groups. From these patients, 560 sagittal CBCT images of the maxillary central incisors were examined to measure the labial and palatal bone thickness at the apex level and the palatal bone at the mid-root level, according to the SRP classification. The chi-square test, Kruskal-Wallis test, and multiple linear regression were used for statistical analyses. Results: Significant differences were found in alveolar bone thickness depending on the arch form and SRP at the apex level. The square dental arch form and class I SRP showed the highest bone thickness at both levels of the palatal aspect. The taper dental arch form and class II SRP presented the highest bone thickness at the apex level of the labial aspect. No association was found between the dental arch form and SRP. Elderly women showed a significant association with thinner alveolar bone. Age-sex group, the dental arch form, and SRP had significant associations with alveolar bone thickness at the apex level. Conclusion: The patient's age-sex group, dental arch form, and SRP were associated with alveolar bone thickness around the maxillary central incisors with varying magnitudes. Therefore, clinicians should take these factors into account when planning immediate implant placement.
