DESCRIPTION OF CERTAIN EMBODIMENTS OF THE PRESENT INVENTION

(7) In the following detailed description of the preferred embodiments, reference is made to the accompanying drawings, which form a part of this application. The drawings show, by way of illustration, specific embodiments in which the invention may be practiced. It is to be understood that other embodiments may be utilized and structural changes may be made without departing from the scope of the present invention.

(8) The present invention 10 could comprise of bone foundation guide 20 that can accommodate and support a dental implant surgical guide 50 and a respective method or process of such use 100. Both the bone foundation guide body 22 and the dental implant surgical guide 50 may be designed and created together through digital dentistry in which scans of patient's mouth (along with impressions and castings thereof) may be used to create a virtual model of the patient's existing mouth; to develop a virtual model of the patient's mouth both pre-dental and post-dental surgery; and to develop a dental surgical plan that connects the two patient-specific virtual models. In this manner, the dental surgical planning can provide for the manufacture of the two respective guides so that the contours of the bone foundation guide body 22 may be created to fit upon the bone 14 of the dental surgical site 12 and as well as properly interact with the contours of the dental implant surgical guide 50 enabling the dental implant surgical guide 50 to fit upon the bone foundation guide body 22.

(9) As substantially shown in FIGS. 1 and 2, the bone foundation guide 20, as substantially used by a dental surgeon (not shown) to substantially reduce or augment the bone structure of the dental surgical site 12 as needed for a successful dental surgery, could comprise a bone foundation guide body 22 with a buccal wall 24 and lingual wall 26 connected together at their respective ends by a first end 28 and a second end 30. The first end 28 and the second end 30 could be holding the walls 24, 26 apart from one and other, in a substantially parallel fashion, to generally create and define an open surgical space 32 (e.g., generally passing through the bone foundation guide body 22 to generally continuously connect a portion of the top 34 with a portion of the bottom 36).

(10) The bone foundation guide body 22 may be penetrated by one or more attachment apertures 38 to generally continuously connect the top 34 and bottom 36, although in some embodiments the attachment apertures 38 may be oriented to pass through a buccal 24 wall and/or lingual wall 26. Fasteners 40 may pass through the attachment apertures 38 to substantially anchor into the bone 14 of the dental surgical site 12 (e.g., alveolar ridge) to reversible secure the bone foundation guide body 22 to dental surgical site 12. The attachment aperture 38 could further feature a reinforcement collar (not shown) to support and guide the fastener 40 through the attachment aperture 38.

(11) In some embodiments, the bone foundation guide body 22 may further comprise a first alignment feature such as a bridge 42 that connects the buccal wall 24 with the lingual wall 26 between the first end 38 and the second end 30 and effectively bisecting the open surgical space 32 in some versions of the embodiment. The bridge 42 in such embodiments may also have an attachment aperture 38 penetrating it as well.

(12) As substantially shown in FIGS. 3 and 4, the dental implant surgical guide 50 could be generally used to guide and locate the placement of dental implants in dental surgical site 12. The dental implant surgical guide 50 could comprise a dental implant surgical guide body 52 having a first end side 53 and second end side 54 that terminates the dental surgical guide body 52 and along with a top side 58 and a bottom side 60 that continuously connect a buccal side 62 with a lingual side 64. The bottom side 60 could be designed and/or contoured to receive the top 34 of the bone foundation guide 20 to allow the dental implant surgical guide 50 to be combined with and attached to the bone foundation guide 20.

(13) The dental surgical guide body 52 can be further penetrated by implant apertures 66 that could continuously connect the top side 58 to the bottom side 60 to guide implant preparation and attachment to the dental surgical site 12. The dental surgical guide body 52 could additionally have fastener apertures 68 penetrating the dental surgical guide body 52. The fastener apertures 68 may align up with the respective attachment apertures 38 on the bone foundation guide body 22 so that an extended fastener 70 may pass through both the dental implant surgical guide 50 and the bone foundation guide 20 to attach to the bone 14 relative to the dental surgical site to combine the two guides 20, 50 in place at the dental surgical site 12. In other embodiments, the fastener apertures 68 may align up with respective receptacles in the bone foundation guide body 22 to allow the fasteners 40 passing through the dental surgical guide 20 to anchor into the bone foundation guide body 22 to combine the bone foundation guide 20 with the dental implant guide 50. In this manner, the dental implant surgical guide 50 could: attach directly to the dental surgical site 12; attach to the dental surgical site 12 through the bone foundation guide 20; attach to just the bone foundation guide 20; or combinations thereof.

(14) The bottom side 60 of the dental implant surgical guide 50 can be digitally designed/manufactured to have a contour (e.g., top side 58) that substantially matches the top 34 of the bone foundation guide 20. Conversely, or conjointly, the top 34 of the bone foundation guide body 22 may be digitally designed and created to substantially match and to receive the bottom side 60 of the reciprocal dental surgical guide body 52 to allow the dental implant surgical guide 50 to be mounted to the bone foundation guide 20 so that the bone foundation guide 20 can be joined with the dental implant guide 50 to act as a base for the dental implant surgical guide 50. This conjoining of guides 20, 50 could alleviate the need to remove the bone foundation guide 20 from the dental surgical site 12 prior to attaching the dental implant surgical guide 50 to the dental surgical site 12 as well as alleviate the need to attach the dental implant surgical guide 50 directly to the dental surgical site 12 and the like. In this manner, the dental implant surgical guide 50 generally encloses the open surgical space 32 to allow implants/implant accessories (e.g., implant preparation tools)(not shown) passing though the dental implant surgical guide 50 to be generally pass through an open surgical space 32 of the bone foundation guide 20.

(15) In one possible embodiment, the bottom side 60 of the dental implant surgical guide 50 could have a second alignment feature such as a recess 72 that could accommodate the bone foundation guide's bridge 42. If the bridge 42 was penetrated by an attachment aperture 38, the dental implant surgical guide body 52 could have a respective fastener aperture 68 that could align together to allow passage of the extended fastener 70. Similarly, if an implant aperture 66 penetrated the recess 72 then a suitable aperture or channel could penetrate the bridge 42 to allow implant preparation and attachments to penetrate the bridge 72 as well. In another possible embodiment, the bridge 72 could be cut and removed from the bone foundation guide body 22 so that any implant/implant preparation (e.g., drills, reamers, etc.) could pass unimpeded through that opened-up portion of the open surgical space 32.

(16) As substantially shown in FIG. 5, one other possible embodiment of the invention 10 could further comprise a tissue spacing gasket 80 that fits between the dental surgical site 12 and the bottom 36 of the bone foundation guide 20. The tissue spacing gasket 80 could be used to set apart the bottom 36 of the bone foundation guide from the dental surgical site 12 to properly replicate the positioning of the dental implant surgical guide 50 (as placed on top 34 of the bone foundation guide 20) as if the gum tissue 16 had been reattached to the surgical (bared bone) site. The thickness of the tissue spacing gasket 80 could be set to the thickness of the gum 16 at that dental surgical site 12 while the gasket bottom 82 can be designed/manufactured to have a contour that matches that of the dental surgical site 12 while the gasket top 84 is contoured to match the bottom 36 of the bone foundation guide 20.

(17) The tissue spacing gasket 80 could be designed and constructed to have own a gasket open surgical space that could generally match the footprint of open surgical space 32 of the bone foundation guide 20. Alternatively, the tissue spacing gasket 80 could have individual gasket apertures (not shown) that could be in alignment with the dental implant surgical guide's implant apertures 66. Other versions of the tissue spacing gasket 80 could have additional apertures (not shown) as needed to be in alignment with any fastener apertures/attachment apertures as needed.

(18) As substantially shown in FIG. 6, one possible method or process 100 for the use of the invention could start with step 102, digital scanning and modeling for the patient-specific dental surgery. In this step, dental digital methods (digital dentistry) may be used in creating patient-specific map of the patient's mouth (which could include the digital scanning of analogue appliances such as patient specific castings and impressions); in creating models for patient-specific bone remodeling (e.g., foundation and re-contouring) of the upper and/or lower dental arches in the patient's mouth; in creating models for dental implant surgical guides/bone foundation guides and prosthetics used post-patient-specific bone remodeling; in creating a patient specific model of the patient's mouth post dental surgery. After this step is substantially completed, the process 100 could proceed to step 104, creation of the guides and other dental appliances.

(19) In step 104, creation of the guides and other dental appliances, the acquired and processed modeling data can be used to create the patient-specific bone foundation guide and patient-specific dental implant surgical guide that can work in combination as one unit. In this manner, the contours of the bottom side of the dental implant surgical guide can be substantially designed and manufactured generally match the top of the bone foundation guide to allow the two guides to mate together. This mating capability could allow the two guides to come together to form a single apparatus to generally create a dental implant surgical guide that could attach to the bone foundation guide (e.g., as already secured to the dental surgical site). This ability could allow the implant/implant apparatuses being guided through the dental implant surgical guide/the open surgical space to properly interact with the dental surgical site. After this step is substantially completed, the process 100 could proceed to step 106, surgical prep.

(20) In step 106, surgical prep, the dental health care professional could (after properly anesthetizes the patient and instituting other required dental surgical pre-operation protocols) could make incisions in the gum area of the dental surgical site, and peel back the gum to expose the portion of bone being operated upon. After this step is substantially completed, the process 100 could proceed to step 108, use of the bone foundation guide.

(21) In step 108, use of the bone foundation guide, the bone foundation guide is properly placed upon to the dental surgical site (e.g., its bottom being contoured to match and receive the exposed bone portion) and properly secured to the site (e.g., fasteners passing through the bone foundation guide to anchor into the bone structure of the dental surgical surgical site). The dental health care professional can then use the bone foundation guide (e.g., BFG) to reduce or augment the bone structure as required utilizing known dental techniques for same to prove the proper bone contour. Once this step is substantially completed, the process 100 could proceed to step 110, use of the dental implant surgical guide.

(22) In step 110, use of the dental implant surgical guide, the dental health care professional could place the bottom side of the dental implant surgical guide upon the top of the bone foundation guide generally enclosing the open surgical space. Fasteners could then penetrate through the surgical guide to embed themselves into the body of the bone foundation guide to secure the surgical guide into place upon the bone foundation guide. In addition or alternatively to this attachment, the fasteners could pass through dental implant surgical guide to directly secure the surgical guide into place upon the dental surgical site. In addition to or alternatively to this attachment, extended fasteners could penetrate through the both bodies of the bone foundation guide and the dental implant surgical guide and into bone of the dental surgical site.

(23) In one embodiment of the invention, prior to the attachment of the dental implant surgical guide to the bone foundation guide, a tissue spacing gasket may be inserted between the prepared dental surgical site and the bottom of the bone foundation guide. This tissue spacing gasket adjusts the combination for the depth of the gum tissue normally present at the dental surgical site but that has been peeled back at the onset of surgical operations.

(24) The dental healthcare professional could use the two guides combined to substantially direct and operated implant preparation accessories or implements (e.g., drills, reamers, and the like) to properly prepare the dental operation site to receive the implant(s) (e.g., pass through the dental implant surgical guide and into the open surgical space. This preparation could ensure the proper orientation and telemetry of the implant accessories into the bone of the dental surgical site. Once the bone is properly prepared, the implant(s) could then pass through the combination to be anchored into the bone. Once this step is substantially completed, the process 100 could proceed to step 112, removal of the guides.

(25) In step 112, removal of the guides, once the implant(s) is (are) properly located in place within the dental surgical site, the fasteners for the bone foundation guide and/or the dental implant surgical guide could be removed to generally allow the combined guides or the guides individually (as well as any tissue space gasket, if used) to be removed from the dental site.

(26) This process 100 could now allow the attachment of trans mucosal abutment, use of temporary cylinder/associated seal/additional filling methods to properly prepare the dental implant for the attachment of prosthesis and the like. At that time, the dental prosthetics could be checked for fitting upon the placed implant(s). If the prosthetics do not need adjustment, they can be removed from the implant and healing abuts can be fitted in their place as required. The gum tissues can then be sutured or otherwise cover-up the exposed bone to meet up with the abutment/implants. If abutments are not required, then the prosthetic could be placed upon the implants in a secure fashion. If the gum tissues need to heal or need to heal around the healing abutments or the implants require ossification to secure them in place to the bone, then after these event(s) have occurred/or a suitable amount of healing time has passed then the prosthetic could be placed upon the implants in a secure fashion. After this step is substantially completed, the process 100 could proceed back to step 102 as needed.

CONCLUSION

(27) Although the description above contains many specifications, these should not be construed as limiting the scope of the invention but as merely providing illustrations of some of the presently preferred embodiments of this invention. Thus, the scope of the invention should be determined by the appended claims and their legal equivalents rather than by the examples given.

(28) As shown in the specification, drawings, claims and abstract, the invention provides for the combining together as one unit, a bone foundation guide and a dental implant surgical guide that generally are otherwise used separately. By digitally designing the two guides to be combined together, the time, effort, cost and patient recover time can be reduced for dental implant procedure. In further combining the two guides with a tissue spacing gasket, the combination can now take into account the depth of the tissue that otherwise would be present at the dental surgical site. The guides reversibly combination consequentially properly places and secures a dental implant-retained prosthesis in a manner that reduces patient stress and bruising that may occur if the two guides were applied separately. The designing of the guides (and gasket) to be conjoined to generally allow implant appliances, implants and securing/attachment fasteners to pass through the combination onto the bone at a dental surgical guide.
