Abstract

A dental implant delivery system and assembly for inserting a dental implant into a pre-drilled bore in the jawbone is discussed. The dental implant assembly system includes an implant body to which is attached a healing cap for covering the central socket in the implant body during the healing period. The healing cap is mechanically coupled to the implant body before the insertion procedure by a coupling screw extending through bore in the healing cap into the central socket of the implant body. A recess in the bottom of the healing cap mates with a protrusion on the top of the implant body such that the healing cap is prevented from rotating relative to the implant body. A torque drive adapter engages the top of the healing cap for easy manipulation of the implant body/healing cap during the insertion procedure. The dental implant, healing cap, coupling screw and torque drive adapter are packaged together in a sterile package. Removing the top portion of the sterile package exposes the top of the torque drive adapter. A tool is attached to the adapter and used to transfer the implant to the jawbone and to insert the implant into the pre-drilled bore. The torque drive adapter is disengaged from the healing cap after the insertion procedure thereby leaving the implant body and healing cap in the jawbone.

Claims

1. A method for inserting a dental implant comprising the steps of:

drilling a hole in the jawbone below the gums;

removing a top portion of a package,

securing a tool to the implant while the dental implant is supported by a remaining portion of the package,

removing the dental implant from the remaining portion of the package;

transporting the dental implant to the hole in the jawbone;

applying torque to the dental implant via the tool; and

disengaging the tool from the dental implant.

2. The method of

claim 1

, wherein the removing a top portion step includes unscrewing the top portion from the remaining portion.

3. The method of

claim 1

, wherein the removing a top portion step includes unsnapping the top portion from the remaining portion.

4. The method of

claim 1

, wherein the removing a top portion step of the package includes exposing a top portion of an adapter that is pre-attached to the dental implant.

5. The method of

claim 4

, wherein the securing a tool to the implant step includes attaching the tool to the top portion of the adapter and the disengaging the tool from the dental implant steps includes disengaging the adapter from the dental implant.

6. The method of

claim 1

, wherein the removing a top portion step of the package step includes exposing a top portion of an adapter that is pre-attached to a healing cap, which is pre-attached to the dental implant.

7. The method of

claim 6

, wherein the securing the tool to the dental implant step includes attaching the tool to the top portion of the adapter and the disengaging the tool from the dental implant step includes disengaging the adapter from the healing cap, which is attached to the dental implant.

8. The method of

claim 1

, wherein the securing the tool to the dental implant step includes holding the remaining portion of the package in one hand while holding the tool in another hand.

9. The method of

claim 1

, wherein the tool is a dental handpiece.

10. The method of

claim 1

, wherein the tool is an implant carrier.

11. The method of

claim 1

, wherein the tool is a friction handpiece driver.

12. A package for storing a dental implant assembly in a sterile environment comprising a first portion and a second portion that is attached to the first portion, the dental implant assembly including at least a dental implant and an adapter that is secured to the dental implant, the package being configured such that when the first portion is separated from the second portion an upper portion of the adapter is exposed while the dental implant remains contained within the second portion.

13. The package according to

claim 12

, wherein the dental assembly further includes a healing cap that is pre-attached to the dental implant.

14. The package according to

claim 12

, wherein the adapter is secured to the dental implant via the healing cap.

15. The package according to

claim 12

, wherein the package is conically shaped.

16. A dental implant delivery system to be used in implanting a dental implant within an osteotomy formed in a jawbone, comprising:

a dental implant having a top end and a bottom end, the bottom end being insertable into the osteotomy, the dental implant further having a threaded central socket extending from the top end toward the bottom end, the socket being open at the top end of the dental implant;

a healing cap having a top and a bottom and a central bore extending therethrough, the healing cap sized and shaped so as to sealingly engage the top end of the dental implant to substantially prevent bacteria or debris from entering the central socket during an initial healing period, the healing cap further comprising a first connector for receiving a torque drive adapter;

the torque drive adapter having a top end and a bottom end, the bottom end of the adapter being formed with a second connector which is engageable with the first connector in the top of the cap for engaging and applying torque to the cap to thread the dental implant into the hole formed in the jaw bone;

the top end of the dental implant and/or the bottom of the healing cap further having a rotational lock to prevent relative rotation of the healing cap and the dental implant when the healing cap is engaged with the dental implant;

a coupling screw having a head seated against the top of the healing cap and a shaft extending through the central bore in the healing cap and threading into the threaded socket in the dental implant, the coupling screw securely coupling the healing cap to the implant body; and

a package that includes a top piece and a bottom piece;

wherein the dental implant, the healing cap, the coupling screw, and the torque driver adapter are pre-assembled and packaged and supported in the package such that when the top piece is removed the top end of the torque driver adapter is exposed.

17. The dental implant delivering system as in

claim 16

, wherein the sterile package is cylindrically shaped.

18. The dental implant delivering system as in

claim 16

, wherein the sterile package is conically shaped.

19. The dental implant delivery system as in

claim 16

, wherein the bottom portion of the sterile package includes a retainer that has a bore with a tapered section configured to support the healing cap.

20. The dental implant delivery system as in

claim 19

, wherein the retainer further includes an O-ring that is configured to secure the dental implant within the bottom portion of the two-piece package.

21. The dental implant delivery system as in

claim 19

, wherein the first connector comprises a plurality of slots formed along the periphery of the top of the healing cap and the second connector comprises a plurality of prongs insertable into the slots.
