The pedestal oral cavity pile body relates to one kind of dental appliance and particular relates to one kind of tooth pile. For releasing stress concentration too much of the joint with pile body and alveolar bone, ensuring rich-looking and prolonging the service life of embedded body, the invention supplies one kind of pedestal oral cavity pile body, which comprises capitutum (1), cervical part (2) and base (3); the horizontal projected area of capitutum (1) and cervical part (2) is less than that of base (3). The cervical part of pile body in this invention adopts column form; the whole adopts narrow-end-up mould, which is the arbitrary shape pile body that the bottom horizontal projected area of embedded body is more than that of top. The pile body structure in this invention breaks through traditional concepts of gradually diminishing from top to bottom for common pile body, adopts enlarged pile base on bottom of pile body and cylindrical pile body on the top, which can release the case in large degree of stress concentration too much of the joint with cervical part of pile body and alveolar bone. |
