무치악은 총의치나 임플란트 보철물로 수복이 가능하며 임플란트를 이용한 피개의치는 총의치보다 유지와 안정이 우수하고, 임플란트 고정성 보철물에 비해 저렴하고 심미적이다. CM $LOC^{(R)}$ $Pekkton^{(R)}$ 어태치먼트는 여자부가 poly-ether-ketone-ketone으로 마모저항성이 뛰어나다. 한편, SR Ivocap system은 가압주사성형법으로 의치의 수직고경 변화가 적고 강도가 우수하다. 본 증례에서 상악은 4개의 임플란트 식립 후 CM $LOC^{(R)}$ $Pekkton^{(R)}$ 어태치먼트와 SR Ivocap system을 이용한 임플란트 유지 피개의치를, 하악은 가철성 국소의치를 제작하였고 심미적 및 기능적으로 만족스러운 결과를 얻었기에 이를 보고하는 바이다.

Construction of an obturator for rehabilitation of a patient who underwent a maxillectomy is vital. Routinely a constructed obturator includes denture portion. A patient who may present anatomical limitations due to surgical or radiotherapy complications often challenges the clinician. Purpose: This clinical report describes a patient with severe trismus after surgical resection and radiotherapy treatment of a tumor in the upper left maxilla. Conclusion: This report describes the concepts of using a rotational path insertion for an obturator and a separately constructed maxillary denture. The stability and retention of the obturator were obtained from anatomical features. Where as these were achieved through magnetic attachments and the remaining edentulous ridge to ensure esthetic and function of the prosthesis.

Purpose: The aim of this case report is to present the longitudinal results of sinus grafting using a new demineralized bovine bone material (DBBM) in human cases. Methods: A patient with a resorbed maxilla was treated by maxillary sinus grafting using a new deproteinized bovine bone material. After a healing period of 6.5 months, three implants were placed and restored. The patient was periodically recalled and followed up for 5 years after restoration. Results: Twelve partially edentulous patients (average age, 55.7 years) were followed up. All patients had insufficient residual height in their maxillary posterior area and underwent maxillary sinus graft surgery to increase the height of their maxilla. In all, 27 fixtures were placed in the augmented bone area. On average, 8.6 months later, implants were loaded using provisional or final restorations. The observation period ranged from 27 to 75 months (average, 43.3 months), and the patients did not show any severe resorption of the graft material or any infection during this time. Conclusions: Our results show that the new DBBM is useful for a maxillary sinus graft procedure. Good healing responses as well as reliable results were obtained for an average follow-up period of 43.3 months.

PURPOSE. The aim of this study was to determine the frequency of significant panoramic radiographic findings and eventual treatment requirements before conventional or implant supported prosthetic treatment in asymptomatic edentulous patients. MATERIALS AND METHODS. A total of 743 asymptomatic edentulous patients were retrospectively evaluated using a digital panoramic system. We analyzed the radiographic findings, including impacted teeth, retained root fragments, foreign bodies, severe atrophy of the posterior maxillary alveolar bone, mucous retention cysts, soft tissue calcifications and radiopaque-radiolucent conditions. RESULTS. Four-hundred-eighty-seven (65.6%) patients had no radiographic finding. A total of 331 radiographic findings were detected in 256 (34%) patients. In 52.9% (n=175) of these conditions, surgical treatment was required before application of implant-supported fixed prosthesis. However, before application of conventional removable prosthesis surgical treatment was required for 6% (n=20) of these conditions. CONCLUSION. The edentulous patients who will have implant placement for implant-supported fixed prosthesis can frequently require additional surgical procedures to eliminate pathological conditions.

In the case of failed fixed implant prosthesis accompanied by abutment screw fracture, fractured screw fragment must be removed to use the existing implant fixtures. A 61-year-old male patient, who had a failed maxillary fixed implant prosthesis accompanied by three abutment screw fracture, hoped to reconstruct the maxillary implant prosthesis, while maintaining the existing implant fixtures. To use the existing implant fixtures, fractured screw fragments were removed. A maxillary implant overdenture using available existing implants was planned. Bar-attachment with Locator was used for implant splinting, denture stability, and retention. Final impression was taken after treatment of peri-implantitis. Jaw relation registration was taken to evaluate available interarch space for bar-attachment. After fabricating bar-attachment, centric relation was taken. Implant overdenture using bar-attachment with Locator was delivered after wax-denture evaluation. This case report showed that a satisfactory clinical result was achieved by implant overdenture using existing implant fixtures in a maxillary edentulous patient.

기존의 의치 인상채득 방법은 치조제 흡수가 심한 환자에게 사용하기에 한계점이 있으며, 의치상을 과도하게 연장하여 문제를 발생시킬 수 있다. 특히나 가동성조직이 존재하는 경우에는 정확한 인상 채득을 하기가 어렵고, 따라서 총의치의 적절한 안착을 방해할 수 있다. 치조제 흡수가 심한 환자에서 폐구법 인상을 이용하여 총의치를 제작하면 더 나은 안정성과 유지를 얻을 수 있다. 본 증례는 86세의 여자환자로 상악 전치부에 치은열성비대가 존재하며 하악의 심한 치조제 흡수를 보이는 무치악 환자이다. 따라서 Centric tray를 이용하여 잠정적인 교합고경을 결정 후 고딕아치 장치를 부착한 맞춤형 트레이를 제작하였고, 폐구법 인상채득을 시행하여 상하악 총의치를 제작하였으며, 의치의 충분한 안정성과 유지력을 얻어 환자의 만족도를 높였다.

수술로 인한 상악골 결손 환자는 저작, 발음, 연하의 기능적 손상과 안모 변형으로 인한 어려움을 겪게 된다. 보철 치료의 목적은 폐쇄 장치를 통해 가능한 한 정상적인 기능과 안모를 회복하는 것이다. 이러한 목표는 재건에 대한 보철과 의사와 외과 의사의 술 전 의사소통을 통해 성취할 수 있다. 본 증례에서는 우측 상악동에 편평상피암 진단을 받은 환자에서 수술 전 치과 검진을 통해 보철적 재건에 대한 계획을 수립하였다. 상악골 절제술 4개월 후 수술용 폐쇄장치, 이행 폐쇄장치를 거쳐 최종 폐쇄장치를 제작하였다. 이를 통해 환자는 저작, 발음, 연하, 안모의 만족스러운 개선을 얻었기에 보고하고자 한다.

This report describes two cases of complete arch implant-supported restorations. The first patient had seven dental implants in each arch with monolithic zirconia frameworks. At four weeks' follow-up, the one-piece maxillary framework was fractured, which was re-designed and re-fabricated using laser-sintered cobalt-chrome alloy. The second patient had four implants in the mandible only. A mandibular monolithic zirconia framework and a maxillary conventional complete denture were fabricated and delivered. At five years' follow-up, the patient reported no significant discomfort. Careful consideration and monitoring of the status of antagonistic arches and stress distribution on zirconia frameworks were suggested for complete arch implant-supported fixed restorations.

Flabby ridges commonly occur in edentulous patients. Inadequate retention and stability of a complete denture are the often encountered problems in these patients. A liquid supported denture due to its flexible tissue surface allows better distribution of stress and hence provides an alternate treatment modality in such cases. This case report presents the use of a liquid supported denture in a patient with completely edentulous maxillary arch with flabby tissue in anterior region opposing a partially edentulous mandibular arch.
