임프란트 지지 오버덴쳐를 이용한 무치악 하악의 수복

There are treatment alternatives that aid in increasing retention and stability when conventional denture therapy is in adequate in the edentulous mandible. The implant-supported overdenture is an especially attractive treatment because of its relative simplicity, minimal surgical trauma and economy. Existing complete denture can be converted and maintain facial support with denture flange when moderate to extreme alveolar ridge resorption is present. The implant-supported overdenture is supported by both implant and mucosa and therefore fewer implants are necessary than for the prosthesis supported only by implants. Numerous studies of implant-supported overdentures in the mandible with good results have been reported. Clinical studies indicate that overdenture treatment has a good prognosis in the mandible. Rehabilitation of the edentulous mandible with implant-supported overdenture is a good choice of treatment.
