Transmandibular implants are used limitedly such as on remaining symphyseal basal bone of atrophic mandible, on the bony defect of symphyseal area due to trauma or tumor as surgical implants. Among the more recent advances in oral implantology are the Fixed Mandibular Implant (FMI)based on the pioneering studies and clinical applications by Irwin Small of the USA and the development very high success rates for providing attachments and abutments in areas of the oral cavity severely compromised by either atrophy or surgical loss of osseous tissues. We will present a case report of regabilitation of totally edentulous mandible with advanced alveolar atrophy using Fixed Mandibular implant (F.M.I).
THE TRANSMANDIBULAR IMPLANT SYSTEM
문홍석,Moon, Hong-Seok 대한치과보철학회 1997 대한치과보철학회지 Vol.35 No.3
Transmandibular implant system은 하악골이 심하게 흡수된 환자에게 특히 유용하게 사용할 수 있다. 또한 여러 문헌에서도 높은 성공률을 보이고 있다. 저자가 시행한 증례에서도 환자는 높은 만족감과 의치의 안정성 및 저작효율의 증대를 보였다. 하지만 성공적인 보철물의 제작을 위해서는 신중한 진단과 치료계획 및 위에서 열거한 여러 가지 고려사항들을 참고해야 한다. Many of the problems which are faced to the edentulous patients are related to a minimal amount of available mandibular bone volume and height. Most of the patients with mild atrophy of the mandible are treated using endosseous implant prosthodontics. TMI(Trans-mandibular Implant) can be used in case of severe mandibular atrophy, poor bone quality, atrophy of the mandible with exposed of inferior alveolar nerve, osteoporosis and the fracture of the atrophic mandible. Also it can eliminate the need for bone grafting and vestibuloplasty. The TMI is a rigid box frame structure which controls and distribute the masticatory force over the severely resorbed mandible. The box frame structure consist of a superstructure, baseplate, 4 transosseous posts, and 5 cortical screws. This is a case report that also describes about the transmandibular implant reconstruction system.
