DETAILED DESCRIPTION
[0032] The present invention may be described herein in terms of various components. It should be appreciated that such components may be realized by any number of structural materials and components configured to perform the specified functions. For example, the present invention may be practiced in any number of dental contexts and the exemplary embodiments relating to a positioning system for implant supported dentures are merely a few of the exemplary applications for the invention. For example, the principles, features and methods discussed may be applied to any crown and bridge restorative dentistry, orthodontics or dental treatment application.
[0033] In accordance with various aspects of the present invention, an implant-supported denture placement and alignment system is provided to accurately position the temporary or final implant-supported denture.
[0034] Recent developments in fully milled monolithic dentures have led to the creation of stronger dentures. For instance, various related systems and methods for manufacturing layered dentures are provided in pages 3-24 of U.S. patent application Ser. No. 14/195,348, entitled SYSTEM AND METHOD FOR MANUFACTURING LAYERED DENTURES and filed on Mar. 3, 2014 and pages 3-18 of U.S. patent application Ser. No. 13/830,963, entitled SYSTEM AND PROCESS FOR MANUFACTURING OF DENTURES and filed on Mar. 14, 2013, and are incorporated by reference herein. For instance, various systems and methods of positioning implant support dentures as discussed herein may be applied to the layered dentures incorporated by reference.
[0035] Similarly, various systems and methods for molding thermosetting plastics, such as to form various features of the system disclosed herein are provided in pages 2-11 of U.S. patent application Ser. No. 13/369,238, entitled PROCESS AND SYSTEMS FOR MOLDING THERMOSETTING PLASTICS and filed on Feb. 8, 2012 and are incorporated by reference.
[0036] Moreover, various systems and methods for reference and registration of implant supported dentures such as for use in combination with various teachings herein are provided in pages 3-22 of U.S. patent application Ser. No. 14/013,295, entitled DENTURE REFERENCE AND REGISTRATION SYSTEM and filed on Aug. 29, 2013 and are incorporated by reference, as are various systems and methods for reference and registration of implant supported dentures such as for use in combination with various teachings herein which are provided in pages 3-22 of U.S. patent application Ser. No. 14/698,649, entitled DENTURE REFERENCE AND REGISTRATION SYSTEM and filed on Apr. 28, 2015, and which are also incorporated by reference.
[0037] Thus, in accordance with various aspects of the present invention, a permanent implant-supported denture denture may also comprise an implant-supported denture, such that a single denture may serve as both the temporary post-operative denture, and the patient's permanent denture. For instance, such a denture may in various embodiments omit a custom support bar and yet, exhibit sufficient strength and durability to serve as a final detachable permanent implant-supported denture.
[0038] In accordance with various aspects of the present invention, a method of positioning implant-supported dentures is provided. In various embodiments, implants may be placed in a patient's jaw. The implant installation sites may be established by use of a surgical guide. For instance, a surgical guide may guide a drill to bore holes in the bone of the patient's jaw and may also guide positioning of the implants. The surgical guide may be positioned in a patient's mouth and anchored prior to drilling. The surgical guide may be positioned and anchored by at least one of buccal and labial pins anchoring the surgical guide in the jaw.
[0039] The surgical guide may be scanned to collect a digital model of the surgical guide, or the electronic data used to create the surgical guide may be used to collect a digital model of the surgical guide. Based on the digital model, the positioning of the at least one buccal and labial pin may be copied to a digital model of an implant-supported denture, such as to create corresponding apertures in the model of the implant-supported denture. The implant-supported denture may be manufactured, and the corresponding apertures may permit the surgeon to easily position the implant-supported denture using the same buccal and/or labial pin positioning as in the surgical guide. In this manner, the implant-supported denture may be positioned precisely and accurately corresponding to the location digitally modeled and corresponding to the surgical guide.
[0040] The surgeon may anchor the implant-supported denture using the labial and/or buccal pins. Upon anchoring, temporary copings and/or abutments on the implants may be bonded to the implant-supported denture. Because the temporary denture has apertures corresponding to the buccal and/or labial pins of the surgical guide, the implant-supported denture has been positioned precisely and accurately according to the intended position electronically modeled to facilitate the proper relationship of the implant-supported denture to the implants. In this manner, when the temporary copings and/or abutments are bonded to the implant-supported denture, they are bonded at the desired sites to allow the implant-supported denture to be installed and exhibit proper balanced occlusion.
[0041] The implant-supported denture can now be removed, such as by the removal of buccal and/or labial pins, and released from the jaw. In various embodiments, the apertures corresponding to the buccal and/or labial pins of the surgical guide are oriented in a portion of the implant-supported denture that can be broken off prior to use by the patient. For instance, the positioning system may be removable in accordance with the systems and methods for dentures and for surgical guides disclosed in pages 2-12 of PCT Application No. PCT/US2014/017136, entitled REMOVABLE SYSTEM AND METHOD FOR DENTURES AND SURGICAL GUIDES and filed on Feb. 19, 2014, which are incorporated by reference as well as the systems and methods for dentures and for surgical guides disclosed in pages 2-12 of U.S. Provisional Patent Application No. 61/766,660, entitled REMOVABLE SYSTEM AND METHOD FOR DENTURES AND SURGICAL GUIDES and filed on Feb. 19, 2013, which are also incorporated by reference.
[0042] Accordingly, with reference to
[0043] Having disclosed an exemplary method of positioning a temporary and/or permanent implant-supported denture, with reference now to various Figures, the positioning system for implant-supported dentures is discussed in greater detail below. For example, with reference to
[0044] An implant-supported denture placement and alignment system 10 may be used to both site implants being installed in a patient's jaw, and to then transfer the implant sites to an implant-supported denture to be installed on the implants and to be worn by the patient. However, as discussed above, fully milled dentures may omit the use of a custom support bar to connect the implant-supported denture to the implants. As also discussed, it is desirable to match the implant sites both accurately and precisely to the denture base and account for any variations that may have arisen between the models used to create the surgical apparatus 18, and the actual patient outcome that includes the actual positioning of implants in the patient's jaw. Similarly, it is desirable that the denture base be installed immediately after surgery but also be usable as the permanent denture base 20 for long-term patient usage.
[0045] A surgical apparatus 18 may comprise a surgical guide 2 and a surgical guide positioning system 50. The surgical guide 2 may attach to a patient's jaw 1 and may provide guidance to the surgeon when drilling the jaw to accommodate implants. For instance, the surgical guide 2 may rest against a patient's edentulous ridges and/or jawbone and provide guidance to a drilling rod entering the jawbone. Surgical guide positioning system 50 may comprise an apparatus whereby the surgical guide 2 may be positioned relative to the jaw 1 and retained in fixed position relative to the jaw 1 while the surgeon is drilling the implant sites.
[0046] A denture apparatus 7 may be at least a portion of a denture prosthesis installed for patient wear such as a part of a temporary implant-supported denture or a permanent implant-supported denture. The denture apparatus 7 may comprise a denture base 20. The denture base 20 may provide support to artificial teeth making up a patient's denture. The denture base 20 may be positioned relative to a patient's edentulous ridges by a denture base positioning system 30. The denture base positioning system 30 may comprise a positioning aid that corresponds to the surgical guide positioning system 50. In this manner, the denture apparatus 7 may be aligned to correspond to the surgical apparatus 18, such as so that the implant sites may be transferred to the denture apparatus 7. For instance, the denture base positioning system 30 and the surgical guide positioning system 50 may comprise similar features so that each are aligned similarly to a patient's jaw 1. In various embodiments, the denture base positioning system 30 comprises similar features to the surgical guide positioning system 50, except that the denture base positioning system 30 comprises enlarged features, such as enlarged apertures, thereby permitting compensation of slight variations in the intended placement and actual placement of implant sites. In various embodiments, because variations between the intended placement and the actual placement of implants may arise, variations may be compensated by various mechanisms, such as wherein the implant sites may be transferred from the actual implants installed with aid of the surgical apparatus 18 to the denture apparatus 7, rather than the intended placement being transferred directly from the surgical apparatus 18 itself to the denture apparatus 7. In various embodiments, the denture base positioning system 30 also comprises enlarged features, such as enlarged apertures (relative to the surgical guide positioning system 50), further facilitating this compensation. In this manner, a denture apparatus 7 may be positioned both accurately and precisely relative to a patient's implants.
[0047] For example, with reference
[0048] Various configurations and designs of surgical apparatus 18 are possible. For instance, various positioning members 8a may have various configurations. For instance, with reference to
[0049] A buccal pin 3 may comprise a pin, screw, shaft, mini-implant, or other member connectable to an aperture defined by a positioning member 8a (or positioning member 8b according to
[0050] Similarly, a labial pin 4 may comprise a pin, screw, shaft, mini-implant or other member connectable to an aperture defined by a positioning member 8a (or positioning member 8b according to
[0051] A surgeon may use the surgical apparatus 18 to assist in positioning implants 5 in a jaw 1 such as an edentulous jaw. For instance, with reference to
