A dental implant with expandable engagement portions hinged on the bottom of the implant. The expandable engagement portions may be made of gold and may have a smooth or contoured outer surface and expand outward when an expander is inserted into the implant. To receive the implant, an implant site is created in the jawbone which is wider at the bottom, having a shape similar to the implant when expanded, so that once the expandable engagement portions expand outward, they fill the bottom of the implant site and thereby result in strong mechanical engagement between the implant and the jawbone. The implant is further anchored by horizontal anchoring apparatus configured for insertion into the bone and the implant. Each of the horizontal anchoring apparatus may anchor the implant onto only one wall, making it possible to use such anchoring apparatus in the event that a wall is missing.
