  • Interproximal contact loss (ICL) is the most frequent complication in partially edentulous patients treated with implant-supported prostheses. However, in most cases, ICL occurs between the implant prosthesis and the natural tooth due to the movement of the natural tooth. There are several causes of ICL that occur between an implant prosthesis and a natural tooth. There are only a few reported cases of ICL occurring between implant prostheses, and explaining the causes of ICL between implant prostheses and natural teeth is challenging. This clinical report describes cases of ICL between implant prostheses and discusses its causes and countermeasures.

  • When treating partial edentulous patients, it is important to use an appropriate restorative materials. Inappropriate restorative materials can adversely affect the outcome of prosthetic restorations. Zirconia and dental metal, which are currently and widely used materials, have a higher elastic modulus than cortical bone, so when an external force is generated, a harmful force can be applied to the implant and the bone around the implant. Polyetherketoneketone (PEKK), a recently introduced material, has a elastic modulus similar to that of cortical bone, and has many advantages in terms of physical properties and biocompatibility. This case report describes that implant-supported fixed prosthetic treatment using PEKK was performed, and functional and esthetic satisfactory results were obtained.

  • Compared with traditional full dentures, mandibular implant overdentures have the advantage in that good support and retention can be obtained even with two implants. When manufacturing a mandibular implant overdenture using two implants, it is important to place the implant in the correct position. The long-term prognosis of overdenture is good when two implants are placed in the direction vertical to the occlusal plane and parallel to each other at the canine position. However, it is difficult to place two implants in the correct position in edentulous patients, and if you use surgical guides in these cases, you can get help in placing the implants in a prosthetically advantageous position. This case, a 57-year-old male patient, came to our hospital with all upper and lower teeth removed due to periodontal disease. Therefore, the maxilla was restored with a traditional full denture and the mandible was restored with an implant overdenture using two implants, which resulted in satisfactory functional and esthetic results.

  • 치과용 임플란트(Implant)란 상실된 자연치아를 대신하여 골 내에 매식하는 인공치근을 말한다. 임플란트는 인접 자연치아의 보호, 심미적 안정 등의 장점으로 인해 그 수요가 늘어나고 있으며, 단일치아 임플란트의 경우, 부분 무치악 환자들에게 있어서 우수한 치의학적 해법이 되어왔다. 대부분의 임플란트는 두 개 이상의 구성요소로 이루어져 있으며, 각각의 구성요소는 나사에 의해 결합되어 있다. 많은 연구결과를 통해, 임플란트의 나사 풀림 현상(Screw loosening)은 임플란트와 관련하여 가장 흔한 문제로 나타나고 있다.(중략)

  • Since the implant became the important treatment modality in dentistry, the research and clinical effort to mimic natural tooth appearance have been pursued. While the rehabilitation of mastication and occlusal appearance was focused in the past, more esthetic and functional restoration was preferred recently. To fulfill this demand, the clinicians should consider the axial contour, papilla space, subgingival appearance, as well as the shape of occlusal surface. In the surgery part, there have been significant advances in the adequate formation of bone and soft tissue through the careful reflection on the surgery time and incision. When the dentist has good knowledge about this aspect and passion for the final product, he or she can acquire better results.

  • 인류의 평균수명이 지속적으로 연장되고 삶의 질을 향상시키려는 욕구가 증가함에 따라 고급 의료기술에 관한 관심이 크게 증가하고 있다. 기존에는 치아가 결손되었을 때 브릿지라는 보철물이나 틀니를 사용하였으나 인접 치아 및 잇몸에 손상을 주는 부작용이 있었다. 최근 널리 보급되고 있는 임플란트 시술법은 결손된 치아 자리에 인공치아를 심는 방법으로서, 치아가 소실된 부분에 치아뿌리 모양의 임플란트를 매식하여 턱뼈에 고정시킨 후 여기에 크라운을 연결하여 보철을 완성한다.(중략)
