Immediate provisional implant
First Claim
1. A restorative dental method for treating a partially or fully edentulous patient, comprising the following steps:
- providing one or more permanent implants extending through the crestal bone of a patient'"'"'s mouth at one or more permanent implant sites for supporting one or more final dental restorations; and
providing one or more provisional implants extending through the crestal bone in the patient'"'"'s mouth adjacent the permanent implant sites for supporting one or more provisional dental restorations, each of the one or more provisional implants including a threaded segment;
drilling an osteotomy adjacent the permanent implant site;
twisting the provisional implant into the osteotomy;
bending a segment of the provisional implant adjacent the threaded segment; and
whereby one or more provisional dental restorations may be supported by the provisional implants during an initial healing period while substantially avoiding forces being exerted on said permanent implants.

Abstract
An immediate provisional implant is provided, and method of use therefor, that serves to protect permanent dental implant anchors and overlying tissue during the healing and osseointegration process. Potentially damaging forces resulting from patient use of a temporary prosthesis during the osseointegration period are carried by the immediate provisional implant, rather than impinging upon non-osseointegrated permanent implant anchors or overlying tissue. The immediate provisional implants are self-threading and are inserted in osteotomies located near permanent dental implant anchors. The temporary prosthesis is removed after a period allowed for osseointegration of the permanent implant anchors, and the provisional implants can also be removed at the same time. The immediate provisional implants are non-linearly tapered from a maximum thread diameter near the bone surface to a more narrow distal end, providing immediate stability without the benefit of osseointegration.

3. The method of claim 2, further comprising removing the provisional implants prior to bearing the permanent prosthesis.
-
4. The method of claim 2, wherein bearing the provisional implant comprises receiving forces acting on the provisional prosthesis while the permanent implant osseointegrates.
-
5. The method of claim 2, further comprising, after providing the provisional implant and prior to bearing the temporary prosthesis, temporarily attaching an extender to the provisional implant in order to better display its orientation.
-
6. The method of claim 1, further comprising removing the provisional implant after a period during which the permanent implant osseointegrates.
-
7. The method of claim 1, wherein twisting comprises engaging with a torque providing tool a portion of the provisional implant between a threaded segment and an opposite end.
-
8. The method of claim 1, wherein bending is performed after the provisional implant has been placed in the osteotomy.
-
9. The method of claim 1, wherein providing the provisional implant is performed after providing the permanent implant.
-
10. The method of claim 1, wherein the provisional implant has a maximum width of less than about 3.5 mm.
-
11. The method of claim 10, wherein the provisional implant is provided at a provisional implant site at least about 3 mm from the permanent implant site.
-
12. The method of claim 1, wherein said provisional prosthesis is attached to the immediate provisional implants using a temporary adhesive.
-
13. The method of claim 1, further comprising creating a temporary dental prosthesis for engagement with the provisional implant.
-
14. The method of claim 13, wherein creating the temporary dental prosthesis comprises adapting an existing denture to be attached to engage the provisional implant.
-
15. The method of claim 13, wherein said creating comprises the steps of approximately shaping an autopolymerizing, tooth-colored acrylic within the patient'"'"'s mouth after providing the provisional implant and further refining this acrylic before temporarily attaching the prosthesis to the provisional implant.
-
16. The method of claim 13, further comprising closing a patient'"'"'s gum over the permanent implant prior to temporarily attaching the prosthesis to the provisional implant.
-
17. The method of claim 13, wherein said creating comprises
taking an in-mouth impression with a resilient impression material after the immediate provisional implants are inserted; - and
shaping the provisional dental prosthesis outside of the patient'"'"'s mouth, based on information obtained from the in-mouth impression.
- and
-
18. A method for providing a fixed, temporary dental prosthesis during a healing period for allowing osseointegration of two or more permanent implants implanted into the jaw bone of a patient, comprising:
-
implanting one or more provisional implants in the jaw bone at positions generally between the permanent implants, each of the provisional implants including abutment protruding out of the bone;
temporarily attaching an extender to one or more of the provisional implants to better display its orientation;
bending at least one of the one or more provisional implants with a bending tool; and
adhering a temporary dental prosthesis to the abutments such that it is supported by the provisional implants during the healing period while substantially preventing mastication forces from being exerted on said permanent implants. - View Dependent Claims (19, 20, 21, 22, 23)
