임플란트 고정성 보철물 수복을 위한 최소 교합 고경에 대한 고찰

Abstract

Background: The purpose of this review is to exmanine the minimal interocclusal distance required for implant placement for each implant manufacturer without surgery. Materials and methods: “Minimal interocclusal distance” was defined as the distance from the edentulous alveolar crest to the functional cusp of the opposing teeth or to the contact surface facing the central fossa of implant prosthesis. 15 journals were searched by “Pubmed”, and specifications were inquired by manufacturer. Result: Implants were classified into bone level and soft-tissue level implant. The bone level was divided into external connection type and internal connection type. Implants were categorized into cement-retention type and screw-retention type according to the fastening method of the prosthesis. For the cement-retention type, the bone level implant required 6 mm interocclusal distance and the soft-tissue level implant 8 mm, regardless of manufacturer. For the screwretention type, minimal interocclusal distance were 1.5~4.5 mm for internal connection type, 3.65~4.5 mm for external connection type, 4.3~6.5 mm soft-tissue level implant. Conclusion: There were differences in each manufacturer, but implantation can be performed when the minimum interocclusal distance of 1.5 mm is secured.
