A novel dental minipin implant fixture with detachable heads to accommodate either o-ring ball head retainers or a semi-permanently bonded overcase designed to replace a temporary denture. The dental practitioner can offer the economical choice of a removable acrylic denture to be replaced at a later date by a semi-permanently bonded porcelain prosthesis. Simply by changing the abutment head, the implanted minipin serves to anchor either choice of dental appliance.
