DESCRIPTION OF CERTAIN EMBODIMENTS OF THE PRESENT INVENTION
(13) 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.
(14) The present invention 10 could comprise an attachment system 20 and method or process 200 for operating same to attach a dental implant surgical guide to one or more dental implants located at a dental surgical site in a patient's mouth. The employment of the attachment system could allow the dental implant surgical guide to anchor a dental prosthesis to a patient's mouth.

(19) As substantially shown in
(20) The first fastener 40 could be a threaded fastener and have a first fastener head 42 being large enough so that the first fastener head 42 does not pass through the abutment body 32. The first fastener 40 could be further capable of engaging the implant aperture 112 (e.g., threaded) of an implant recess 108 to initially secure the abutment 40 to the dental implant 100. In one possible embodiment, the first threaded fastener 40 could be generally held captive by the abutment body 32 for safety and efficiency reasons. The first fastener 40 could further be a bolt wherein the bolt's head is shaped with flats for removable engagement by a suitable wrench (not shown). The first fastener head 42 could further feature an open-ended fastener recess 44 to which a second fastener 68 could be attached and generally allowing for the attachment of the implant mount 50 to the abutment 30 (as substantially shown in
(21) As substantially shown in
(22) The second mount end 58 could have a mount depression 60 that could accommodate the second fastener head 70 so that second fastener head 70 may not protrude above the second mount end 58 when the second fastener 68 is connected to the first fastener 40. The mount depression 60 could be further suitably fashioned to removably accept a tool 14 that can rotate the assembled or completed implant configuration 90 relative to the dental surgical guide 120, as well as implant shaft 18 (as substantially shown in
(23) The second mount end 58 may have an outwardly projecting protrusion such as a lip or rim 62 whose overall size is too large to allow the rim 62 fit into or through the guide channel 128 but the remainder of the mount body 52 is sized to pass though the guide channel 128. The rim 62 could have a rim circumference 64 that is generally greater than the circumference of the guide channel 128 but not greater than the circumference of the guide cylinder top 126 to provide sufficient implant mount retention capability.
(24) The second fastener 68 could be also threaded (e.g., be a threaded bolt) and have a second fastener head 70 being large enough so that the second fastener head 70 does not pass through the mount body 52. The second fastener 68 could be further capable of engaging the fastener recess 44 so as to connect (e.g., removably) the second fastener 68 to the first fastener 40. This fastener-to-fastener connection could allow the implant mount 50 to be removably attached to the abutment 30 and further provide for the unification of the implant mount 50, abutment 30 and dental implant 100 when assembled into the implant combination 90 outside the patient's mouth. In this manner, the assembled implant combination 90 can then be inserted into the guide channel 128 and rotated as an single unit to drive and anchor the dental implant 100 into a previously prepared dental surgical site 12 (e.g., implant shaft 18) and to generally bring the rim 62 into contact with the guide cylinder 124 (as substantially shown in
(25) As substantially shown in
(26) The cap 72 could further have a suitable cap fixture 84 (e.g. such as a hexagon-shaped tool aperture in the center of the enclosed end 76) that can accept a suitable tool (e.g., a wrench—not shown) that can be used to attach (e.g., rotate) the cap 72 onto the dental implant surgical guide 120. In some embodiments, the cap 72 may be removably attached to the dental implant surgical guide 120.
(27) As substantially shown in
(28) As substantially shown in
(29) As substantially shown in
(30) The cap attachment could be one of the last steps under taken prior to the attachment of the prosthesis 140 to the dental implant surgical guide 120. In that manner, the attachment of caps 72 to the respective implant combinations 90 as place through the guide channels 128 of the dental implant surgical guide 120 could be accomplished using an alternating sequence, such as tightening first the caps 72 located proximate to the back of the mouth 16 and moving towards those caps 72 located proximate to the front of the mouth 16.
(31) As substantially shown in
(32) As substantially shown in
(33) In step 204, the assembling of the implant combination, the abutment can be first attached to the implant with the first abutment end being placed into the implant recess for a generally conical fit that can result in a taper interference fit or Morse's taper connection. The first fastener movably located through the abutment can then attach to the implant aperture at the tip of the conical fit to further hold the abutment and implant together. The implant mount can be connected to the abutment by placing the second abutment end within the abutment cavity of the implant mount so that the flats of the abutment cavity may be aligned with the flats of the second abutment end. The second fastener, movably located in the implant mount, may removably attach to the head of the first fastener to generally hold the implant mount in place upon the second abutment end and to generally complete the assembly of the implant combination. Depending on the number of dental implants that are needed, this step can be repeated several times to complete several implant combinations. Once this step is substantially completed, process 200 could proceed to step 206, placing the dental implant.
(34) In step 206, placing the dental implant, the implant combination could be guided through the guide cylinder top to pass at least a portion of the implant combination through a respective guide channel (and through the bottom prosthesis half). The tip of the implant could initially engage the respective previously prepared implant shaft at the dental surgical site. If an implant analogue is used instead of the dental implant in the assembly of the implant combination, the implant analogue could be directed to an implant analogue shaft at a dental surgical site model. A suitable tool could be attached the second mount end (e.g., a wrench attached to the mount fixture) and the operator such as a dental health care professional can rotate the entire implant combination within the guide cylinder to drive the implant (e.g., or implant analogue) into the implant shaft. Once the implant and hence implant combination is firmly and properly seated within the dental surgical site, the step can be repeated for each additional implant combination that needs to be attached to the dental surgical site (or the dental surgical site model). Generally during this action, the second mount end is substantially brought into closer proximity to the respective cylinder, namely the rim may make contact with guided cylinder top. As this step is substantially completed, the process 200 may proceed to step 208, making adjustments.
(35) In step 208, making adjustments, this is an optional step wherein the implant mount may need to be released from a placed implant combination to allow for removal of the dental implant surgical guide (prosthesis bottom half) from the implant combination. In such a situation, the second fastener may be disconnected from the first fastener so that the implant mount may be removed from the abutment. Depending on the number of implant combinations being located at that time, their respective implant mounts may need to be removed to allow for the full detachment of the dental implant surgical guide from the dental surgical site (or the dental surgical site model).
(36) Once the adjustment, correction, fitting, or the alike has been be made, the dental implant surgical guide could be replaced over the abutments and the implant mounts could be suitably reattached to their respective abutments. This step can be repeated as needed to make the many adjustments, corrections, fittings, or the alike as needed. Once this step is substantially completed, the process 200 could proceed to step 210, fitting the cap.
(37) In step 210, fitting the cap, the cap could be applied to a respective guide cylinder. A suitable tool (e.g., wrench) could be applied to mount fixture on the cap's enclosed end. The cap open end could be directed to and engage the top of the respective cylinder (e.g., the cylinder substantially holding the placed implant combination) so that the cap locking interface (e.g., cap threads) can engage the guide cylinder's locking interface (guide threads). Once the cap has fully engaged the guide cylinder, the tool can be removed. For multiple cap/guide cylinder applications, the caps can be applied and tighten in sequenced order that substantially eliminates possible warped placement of the dental implant surgical guide to the implants and to generally ensured dental implant surgical guide achieves the desired telemetry and position relative to the implants (and patient's mouth).
(38) It should be noted that if needed the caps could be removed from guide cylinders, the implant mounts from the abutments, to release the dental implant surgical guide from the implants (or implant analogues).
(39) As this step is substantially completed, the process 200 could proceed to step 212 attaching the prosthesis. In one version of the prosthesis, the dental implant surgical guide could be attached to the base channel. For the encapsulating or enveloping prosthesis, the prosthesis top half could be attached to the combined dental implant surgical guide and prosthesis bottom half to secure and envelope the dental implant surgical guide within the prosthesis. At the substantial completion of this step, the process 200 could proceed back to step 202 as needed.
CONCLUSION
(40) 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.
(41) As substantially shown in the drawings and generally described in the description, the invention could be a system for attachment of a dental implant surgical guide to one or more implants that allow the dental implant surgical guide to support a prosthesis and secure the prosthesis to the patient's mouth. The system could provide an implant combination that can be used to rotate an implant into place in a dental surgical site. In doing so the implant combination can bring a rim from the implant combination into contact with the guide cylinder top of the dental implant surgical guide. A cap attaching to the rim and dental implant surgical guide can then lock the dental implant surgical guide in place with one or more implant combinations to appropriately attach the dental implant surgical guide to the patient's mouth, allowing the dental implant surgical guide to anchor and support a dental prosthesis.
