The present invention provides for a hybrid dental implant having a screw body with at least one external thread, which includes an upper portion with an open ceiling configured to receive one or more bone inducing agents and/or therapeutic agents, a middle portion having a hollow inner channel connected to side openings, and a lower portion with a closed floor. The bone inducing agents and/or therapeutic agents are introduced through the open ceiling into the hollow inner channel into the side openings, which enables the bone tissue ingrowth into the hollow inner channel and bone tissue outgrowth from the hollow inner channel to the surrounding bone. It also provides for a method of installing and using the hybrid dental implant thereof.

1. A hybrid dental implant comprising: a dental implant body having an external thread on an external surface of the dental implant body, the dental implant body having a length of 15.0 mm or less and a diameter of 5.0 mm or less,the dental implant body comprising an upper portion with an open ceili
1. A hybrid dental implant comprising: a dental implant body having an external thread on an external surface of the dental implant body, the dental implant body having a length of 15.0 mm or less and a diameter of 5.0 mm or less,the dental implant body comprising an upper portion with an open ceiling, a middle portion having a hollow inner channel, and a lower portion with a closed floor;the hollow inner channel comprising a) one portion connected to the open ceiling, which is configured to receive one or more injectable bone inducing agents;b) a lower portion terminating at the closed floor; andc) one or more side openings extending from the hollow inner channel, rotating in a helix-like shape in an opposing direction from that of a plurality of turns of the external thread, wherein the dimensions of the side openings are of sizes designed to enable bone ingrowth into the hollow inner channel and bone outgrowth from the hollow inner channel to the surrounding bone. 2. The hybrid dental implant in accordance with claim 1, wherein the upper portion, the middle portion and the lower portion of the dental implant body located successively along the length of the dental implant body in a longitudinal direction, the upper portion occupying the upper 40% to 50% of the length of the dental implant body, the adjacent middle portion occupying the middle 40% to 50% of the length of the dental implant body, and the lower portion is adjacent to the middle portion, occupying the lower 10 to 20% of the lower or bottom portion of the length of the dental implant body. 3. The hybrid dental implant in accordance with claim 1, wherein the hollow inner channel has a diameter in the range of about 0.5 mm to about 2.0 mm. 4. The hybrid dental implant in accordance with claim 1, wherein the one or more side openings have a width on a surface of the dental implant body in the range of about 0.6 mm to about 1.5 mm. 5. The hybrid dental implant in accordance with claim 1, further comprising a plug-in screw, a healing cap screw, or an abutment screw connected to the open ceiling, extending into the hollow inner channel. 6. The hybrid dental implant in accordance with claim 1, wherein the lower portion comprises one or more self-tapping cuts at a front end of the lower portion. 7. The hybrid dental implant in accordance with claim 1, wherein the bone inducing agent includes bone morphogenetic proteins. 8. The hybrid dental implant in accordance with claim 1, further comprising a hydrogel loaded with bone inducing agents. 9. The hybrid dental implant in accordance with claim 8, further comprising one or more therapeutic agents. 10. A method for installing a hybrid dental implant into a bone, the method comprising: a) screwing a hybrid dental implant with a dental implant body having at least one external thread into a bored hole in the bone, the dental implant body having a length of 15.0 mm or less and a diameter of 5.0 mm or less; andb) injecting a suitable amount of bone inducing agent loaded hydrogel into an open ceiling of the implant, thereby delivering the hydrogel into an upper portion of the implant, whereby the hydrogel moves into a hollow inner channel in a middle portion of the implant with one or more side openings extending from the hollow inner channel, rotating in a helix-like shape in an opposing direction from that of a plurality of turns of the external thread, wherein the one or more side openings extend from a beginning end of the middle portion to a lower end of the middle portion, and through which the bone inducing agent enables bone ingrowth into the hollow inner channel. 11. The method in accordance with claim 10, further comprising a step of injecting medicinal or therapeutic agent into the hollow inner channel. 12. The method in accordance with claim 10, further comprising steps of waiting for a period of time after implantation, and injecting one or more doses of bone inducing agents in the hydrogel into the hollow inner channel. 13. The method in accordance with claim 10, further comprising a step of introducing one or more therapeutic agents into the hollow inner channel of the implant during the implantation. 14. The method in accordance with claim 10, further comprising a step of introducing one or more therapeutic agents into the hollow inner channel of the implant after the implantation. 15. A hybrid dental implant comprising: a dental implant body having an external thread on an external surface of the dental implant body, the dental implant body having a length of 15.0 mm or less and a diameter of 5.0 mm or less,the dental implant body comprising an upper portion with an open ceiling, a middle portion having a hollow inner channel, and a lower portion with a closed floor;the hollow inner channel comprising a) one portion connected to the open ceiling, which is configured to receive one or more injectable bone inducing agents;b) a lower portion terminating at the closed floor; andc) one or more side openings extending from the hollow inner channel, rotating in a helix-like shape in an opposing direction from that of a plurality of turns of the external thread, wherein the dimensions of the one or more side openings are of sizes designed to enable bone ingrowth into the hollow inner channel and bone outgrowth from the hollow inner channel to the surrounding bone, wherein the one or more side openings extend from a beginning end of the middle portion to a lower end of the middle portion.
