Abstract

A tissue borne stackable foundation guide is provided. The foundation guide may include a main body; first connectors formed on and spaced about an outer surface of the main body; one or more ports spaced about the main body and forming a passage therethrough; and protrusions formed on an inner surface of the main body and extending in a generally perpendicular direction therefrom.

Claims (24)

1. A foundation guide, comprising:

a. a main body;

b. first connectors spaced about the main body, wherein the first connectors are connected to the main body at an upper portion of the first connectors and a lower portion of the first connectors extend below a lower surface of the main body, and wherein each of the first connectors comprise a connection sleeve comprising a vertically extending cylindrical passageway therethrough;

c. fixation ports spaced about the main body, the fixation ports forming a passage through the main body; and

d. protrusions formed on an inner surface of the main body and extending in a generally perpendicular direction therefrom, wherein the protrusions are disposed proximate to and distributed at least partially about a periphery of each of the fixation ports.

2. The foundation guide of claim 1 , wherein the protrusions comprise conical shaped bodies tapering to a point at a distal end, and are distributed at least partially about the periphery of each of the fixation ports in a generally triangular pattern.

3. The foundation guide of claim 1 , wherein the protrusions comprise a length, such that when the foundation guide, configured to be seated on a patient's gum tissue, is fully seated on the patient's gum tissue distal ends of the protrusions do not engage underlying bone of the patient.

4. The foundation guide of claim 1 , wherein the fixation ports are configured to receive a device therethrough for fixating and anchoring the foundation guide to a maxillary or mandibular bone of a patient.

5. The foundation guide of claim 4 , wherein the device comprises at least one of a fixation pin and screw.

6. The foundation guide of claim 1 , wherein the first connectors each comprise a first coupling hole, wherein the first coupling hole forms a passageway through the first connector that is substantially perpendicular to a length of the first connector.

7. The foundation guide of claim 1 , wherein the main body comprises a generally curved shape in a general shape configured to be located on a gum line of a patient.

8. The foundation guide of claim 1 , further comprising a stackable component, the stackable component comprising:

a. a component body; and

b. second connectors spaced about an outer edge of the component body, wherein the second connectors are configured to engage with the first connectors.

9. The foundation guide of claim 8 , wherein the second connectors each comprise a second coupling hole, wherein the second coupling hole forms a passageway through the second connectors that is substantially perpendicular to a length of the second connector.

10. The foundation guide of claim 9 , wherein the first connectors and second connectors are configured such that when engaged the second connectors seat into voids formed in corresponding ones of the first connectors, and wherein when the second connectors are seated into the first connectors, the second coupling holes are aligned with first coupling holes formed in the first connectors.

11. The foundation guide of claim 10 , wherein the stackable component is secured to the foundation guide via one or more coupling mechanisms inserted through the aligned first and second coupling holes.

12. The foundation guide of claim 8 , wherein the stackable guide is configured to facilitate a dental procedure.

13. The foundation guide of claim 12 , wherein the stackable guide further comprises one of a surgical component or a prosthetic component formed thereon.

14. A foundation guide, comprising:

a. a main body;

b. first connectors spaced about the main body, wherein the first connectors are connected to the main body at an upper portion of the first connectors and a lower portion of the first connectors extend below a lower surface of the main body, and wherein each of the first connectors comprise a connection sleeve comprising a vertically extending cylindrical passageway therethrough, and wherein the first connectors are generally uniform in shape and size;

c. fixation ports, the fixation ports forming a passage extending from an outer surface of the main body through an inner surface of the main body, the fixation ports configured for receiving a fixation mechanism for fixating the foundation guide to a patient's bone; and

d. protrusions formed on the inner surface of the main body and extending in a generally perpendicular direction therefrom, wherein the protrusions are disposed proximate to and distributed about a periphery of each of the fixation ports.
