Adjustment and/or activity prior to use of parallel alignment tool assembly 200,205, is collectively referred to as a single preliminary stage 700 to collectively refer to the stages for properly placing and/or loading the implant anchor with optional abutment assembly members 10, for example as described in the greater detail in the various stage of FIG. 8 prior to stage 1510b. Most preferably tool 200, 205 may be utilized at the final stages of placement of restoring by means of dental implant, most preferably to affix and/or set an abutment in a parallel position about other abutments and/or teeth.

(88) Although the proceeding description reiterates use of alignment tool assembly 200,205 is provided with respect to a sleeve member 50, the use of tool 200,205 is not limited to use with a sleeve member and may be utilized with any prosthodontic restoration member for example including but not limited to a member of dental implant system 30, a member of abutment assembly 10, post, sleeve 50, 50s, 52, 54, over-denture abutments (for example including but not limited to ball attachments, snap attachments, telescopes), or the like.

(89) Initially in stage 701, at least one or more alignment arm members 220, 222, 224, 226, 228 are coupled with at least one prosthodontic restoration member to be positioned.

(90) Next in stage 704 parallel bridge 210, 218 may be mounted and/or slid over alignment arm member 220 about central recess 216, 218r. As previously described alignment arm members 220 may be introduced into recess 216, 218r optionally by maneuvering or threading bridge 210,218 over alignment arm member 220 through recess 216. 218r. Optionally, according to an optional embodiment of the present invention, bridge 210 comprising an optional hinge member and bridge closing member 214 may be snapped and/or closed over extensions members 220 by assuming an open configuration of bridge 210 (open hinge) and then closing bridge 210 with closing member 214 over alignment arm member 220.

(91) Next in stage 705 filling material (composite material) and/or curable material is introduced into the lumen of sleeve 50 in order to affix and/or set assembly members position. Optionally if abutment assembly 10 includes a locking nut 70 then it is removed from the assembly prior to filling sleeve 50 with the curable materials and then reintroduced over occlusal portion 12a so that occlusal portion 12a may be centered within sleeve 50 and set into the aligned parallel position. Next in stage 707 the curable composite material is allowed to cure, as is known in the art, to set the position of sleeve 50.

(92) Finally in stage 708 once curing is complete, as is known in the art, alignment tool 200,205 and its components bridge member 210,218 and alignment arm members 220, 222, 224, 226, 228 are disassociated from sleeve 50 now in its securely and firmly affixed in final clinical required position.

(93) Now referring to FIG. 8 showing a flowchart depicting an optional methods for placing a dental implant system 30 comprising an abutment assembly 10 while utilizing tool 200 during the advanced stages of the implant restorative process for example as described in greater detail in FIG. 7.

(94) First in stage 1500, the implant anchor 32 is placed within the jawbone according to methods as known in the art.

(95) Optionally placement of the implant anchor may be followed with an optional and appropriate healing time, as depicted in stage 1500a. Optionally the placement of the implant anchor into the jaw bone may be guided with the help of tools such as 200, 205. Optionally locations about recess 220r, 220r, 222r, 224r, 226r, 228r and/or bore 220b, 220S, 220L, 222b, 224b, 226b, 228b may be utilized as guides for drilling a borehole for introducing and implant anchor into a jawbone.

(96) Optionally tool 200,205 according to the present invention may be utilized to determine and/or depict where to place the implant anchor within the jaw bone.

(97) Next in stage 1502 implant anchor 32 is loaded with an optional abutment assembly 10 according to the present invention. Implant's anchor loading comprises an initial sub-stage 1502a for coupling and/or otherwise associating an interface member 40, optionally and preferably comprising an elevated rim 47, with the implant anchor 32 most preferably about bore 36. Next in a secondary sub-stage 1502b abutment pivot 12 is coupled or otherwise associated with anchor 32, with pivot mounting member 16, for example utilizing optional threading 19, 68 or the like threading and/or coupling means. Most preferably abutment pivot 12 is placed through interface member 40 aperture 43 to allow for coupling while stabilizing portion 15 interfaces with internal surface 44 of interface member 40.

(98) Next in stage 1504 the position of abutment assembly 10 is determined, particularly by evaluating the individual's morphology and related prosthodontic requirements to determine the end position of restoration 5 that is to be mounted on abutment assembly 10.

(99) Next in stage 1506, a practitioner adjusts abutment assembly 10 about abutment pivot 12 about any of its portions for example about occlusal portion 12a, adjustment portion 14, or the like. Most preferably adjustment of abutment pivot 12 is provided in accordance with the position determined in stage 1504 therein accounting for and customizing and/or adjusting in accordance with the individual morphology and related prosthodontic requirements of the patient. Preferably, pivot 12 is positioned to protrude substantially perpendicularly to the occlusal plane, and align substantially parallel with abutments and/or teeth of the same jaw. Preferably pivot 12 may be positioned during the procedure by clinician and/or practitioner by adjusting its angle and direction in relation to at least one or more of pivot mounting member 16, the axis of anchor 32, other abutments and/or residual teeth. Preferably, the vertical dimension of abutment 10 assembly may be determined by occlusal reduction of pivot 12, for example by filing or cutting, Optionally vertical dimension of abutment 10 may be extended by extending pivot 12 as necessary, for example with pivot extender 12e, as previously described, to provide the necessary space about the occlusal plane for the structural durability of restoration 5. Optionally and preferably abutment 10 and in particular pivot 12 may be adjusted about occlusal portion 12a with off the shelf tools and/or dedicated and/or proprietary tools and/or pivot or abutment manipulators.

(100) Once abutment pivot 12 is defined in accordance with individual morphology and related prosthodontic requirements to enable optimal positioning and vertical dimension of restoration 5, then interface member 40 is adjusted accordingly in stage 1508. Optionally stage 1506 and 1508 may be performed simultaneously and/or incrementally and/or interchangeably so as to ensure corresponding and/or correlated adjustment to pivot 12 and interface member 40.

(101) In stage 1508 interface member 40 is adjusted to adapt between implant anchor 32, the perio-implant tissues, abutment assembly 10 and/or restoration's margins. Interface member 40 may be individually adjusted, optionally and preferably the adjustment is provided on line and/or in real time, during and/or while the procedure is carried out by the clinician and/or practitioner. Optionally and most preferably interface member 40 is adjusted about rim 47 of interface member 40, such that it is apically reduced by cutting and/or filing in relation to the gingiva, and is adjusted to most preferably be substantially perpendicular (at about a right angle and/or orthogonal) with respect to pivot 12. Therefore most preferably adjusting rim 47 defines and forms the contour of flange 46a therein forming and defining a smooth finish line. Optionally and preferably smoothing the finish line may be provided with standard tool and or dedicated tools. Most preferably a smooth finish line provides for properly engaging and closely fitting the apical end 50a of optional sleeves 50 or sleeve assembly 50s members including sleeves 52, 54, 52b, 54b and/or the apical surface and margins of restoration 5. Optionally the finish line may be defined by rim 53 as previously described.

(102) Most preferably the finish line defined by flange 46, 46a or rim 53 will most preferably be substantially parallel to the occlusal plane, and substantially perpendicular to pivot 12. Preferably the finish line will be located in an area that may be inspected easily by a clinician, cleaned while providing sufficient distance from the alveolar crest to allow the combined epithelial and connective tissue attachment to generate a healthy biologic width. The perpendicular positioning of abutment assembly 10 in relation to the occlusal plane, and the perpendicular positioning of sleeve 54 and/or restoration 5 in relation to the finish line about flange 46, 46a, rim 53, preferably enables for passive support and passive retention increasing resistance form. In addition to being perpendicular to occlusal plane and finish line, the parallel positioning of abutment assembly 10 and the parallel opposite walls of the sleeve determines one path of insertion and retrieval for restoration 5, providing passive support and retention for restoration 5.

(103) Next in stage 1510 the geometry of abutment assembly 10 is determined by adjusting interface member 40 and sleeve 50 or members of sleeve assembly 50s. In sub-stage 1510a interface member 40 is adjusted further to finalize its geometry, shape and length. Most preferably the diameter of the transgingival portion (collar) 49 of interface member 40 may be adjusted. Optionally and preferably the diameter of transgingival portion (collar) 49 of interface 40 may be adjusted so as to be smaller than the diameter of implant anchor 32.

(104) Most preferably adjusting interface member 40 about collar 49 defines a free space along the external anchor's platform providing for a free circular shoulder (also referred to as platform switching or platform shifting as a term of art). Most preferably such fee spaces (shoulder) about collar 49 allows a space onto which hard tissue may proliferate overlapping the implant's contour and improving its fixation and seal, preserving alveolar bone level and providing better support for the papillae. Optionally the reduced diameter of transgingival portion of interface member 40 at collar 49 restricts the contact surface between implant and perio-implant tissue, therein significantly improving the marginal seal of the implant. Most preferably the length of the transgingival portion defined between the alveolar ridge and finish line is optionally and preferably adjusted to ensure the integrity of the biologic width.

(105) Next in stage 1510b following adjustment of the transgingival portion of interface member 40 as described in stage 1510a, sleeve 50 or sleeve assembly 50s members are similarly adjusted about at least one of the sleeve's end, occlusal end 50b and/or apical end 50a. Optionally both ends of sleeve 50 and/or sleeve assembly 50s members may be adjusted as necessary. More preferably, adjustments are made about the occlusal end 50b and optionally to the apical end 50a. Most preferably, the adjustments about sleeve 50 and/or assembly 50s may be provided so as to form an occlusal surface 50b that is substantially parallel with the finish line surface for example defined by flange 46, 46a or rim 53. The length of sleeve 50 may be determined by the distance between the finish line and the required gap about the occlusal plane. Most preferably the length of sleeve 50 is optimized to provide a larger surface area to ensure better retention between abutment assembly 10 members and restoration 5 via the intervening sleeve 50, 52. Most preferably while the length of sleeve 50 is optimized a required gap about the occlusal plane should be provided to ensure the structural durability of the restoration. Preferably the length of sleeve 50 may be adjusted about its occlusal extremity 50b to become substantially parallel with the finish line defined by flange 46, 46a, rim 53. Therein the surface of occlusal end 50b and flange 46a, are most preferably adjusted to form substantially parallel surfaces. Optionally the apical extremity 50a of sleeve 50 may also be adjusted to closely fit the finish line. Next in stage 1512 abutment assembly 10 may be mounted so as to prepare it to receive restoration 5. Most preferably abutment assembly 10 is mounted about pivot 12 that may be accomplished by optional means for example including but not limited to composite build up about pivot 12 or by coupling at least one or more sleeve 50,52 about pivot 12.

(106) Optionally, a buildup about pivot 12 over occlusal portion 12a may be provided, as previously described, wherein filling materials, and/or composite materials may be shaped over pivot 12, for example about engageable portion 13. Optionally buildup about pivot 12 provides for molding and forming composite materials that may later be directly coupled with restoration 5 about bore 5a.

(107) Optionally pivot 12 may be mounted with sleeve 50, 52, 52b or members of sleeve assembly 50s. Optionally the method of coupling sleeve 50 or sleeve assembly 50s about pivot 12 depends on the type of sleeve utilized. Optionally sleeve 50 or inner sleeve 52, 52b comprising inner threading 52t about the luminal surface, be threaded over pivot 12 to couple with engageable portion 13. Optionally sleeve 50 or inner sleeve 52, 52b may be mounted and/or coupled over pivot 12 with filling materials, composite materials or the like. Most preferably sleeve 50 or inner sleeve 52, 52b may be disposed over pivot 12 where the filling material is provided such that the inner lumen 50c is filled with filling materials and/or composite materials to allow the coupling of sleeve 50, 52 with pivot 12.

(108) Preferably coupling sleeve 50, 52 provides for firmly engaging the inner surface 43 of interface member 40 and/or the inner contour of the finish line defined about flange 46, 46a. Most preferably, after coupling sleeve 50 onto pivot 12 the outer contour of the finish line defined by flange 46a, 46, rim 53 is left with substantial width to receive restoration 5 and/or additional sleeves, such that the finish line properly fits with restoration 5 both horizontally and vertically defining a proper emerging profile. Optionally and most preferably once sleeve 50 is introduced over pivot 12 and prior to filling sleeve 50 lumen with filling material alignment tool assembly 200,205 is utilized to ensure proper abutment assembly 10 positioning and parallel alignment as described in greater detail in FIG. 7.

(109) Next stage 1514 restoration 5 is retained to abutment assembly 10. Most preferably restoration 5 may be coupled to abutment assembly 10 by optional means for example including but not limited to telescopic association, cementing, or rigid retainment or the like.

First, the occlusal end 50b of outer sleeve 54 is adjusted such that it is slightly longer then sleeve 52. After length adjusted sleeve 54 is mounted over sleeve 52 so that sleeve 54 engages the finish line defined by flange 46a, 46, rim 53. Next restoration 5 is mounted over sleeve 54 and its profile adjusted about adjacent and opposite teeth and/or restorations until its apical margins passively engages the finish line. Restoration 5 is then passively cemented onto sleeve 54. Optionally and preferably once the adjustment to sleeve 54 is finalized sleeve 54 may be cast and/or integrated with restoration 5 about bore 5a and thereafter mounted onto sleeve 52, 52b. Most preferably, retention of restoration 5 about sleeve assembly 50s is achieved by the passive contact and friction fitting between the surfaces of sleeves 52 and 54, where sleeve 54 slides over sleeve 52 along the path of insertion and retrieval.

(111) Optionally mounting restoration 5 by way of cementing is most preferably provided by cementing restoration 5 with sleeve 50, 52 that are coupled and/or otherwise associated over pivot 12 as described in stage 1512.

(112) Optionally and preferably sleeve 50, 52 may acts as a mold for composite materials and may be removed once composite material hardens and/or cures, therein leaving the molded composite material built up over pivot 12. Next, restoration 5 is mounted over the composite built up and its profile is adjusted about adjacent and opposite teeth and/or restorations until the build up's apical margins passively engages the finish line defined about flange 46, 46a. Finally, restoration 5 is most preferably passively bonded and/or cemented to build up of abutment assembly 10.

(113) A further optional method for retaining restoration 5 over abutment assembly 10 by way of cementing, may be provided by maintaining sleeve 50 intact, not removing it as described above, and directly cementing restoration 5 onto sleeve 50 over bore 5a. Optionally cementing restoration 5 via bore 5a, may be provided with a plurality of sleeves 50 bonded and/or fixed and/or otherwise coupled onto one another so as to provide a proper marginal fit between sleeve 50 and bore 5a of restoration 5.

(114) A further optional method for retaining restoration 5 over abutment assembly 10 may be provided by way of rigid retainment. Preferably the occlusal extremities of abutment assembly 10 including sleeve 52 are adjusted such that sleeve 52 is reduced to lie slightly under the last occlusal threaded engageable portion 13 of pivot 12. Next locking nut 70 is threaded to engage engageable portion 13 of pivot 12. Optionally and preferably locking nut 70 may be threaded with pivot 12 through an aperture provided on the occlusal table of restoration 5. Most preferably locking nut 70 securely locks one or more of sleeve assembly member 50s, 52, 52b, 54, 54b, 50r and/or restoration 5 over pivot 12, most preferably over apical end 70a. Optionally and preferably locking nut 70 also provides for centering sleeve 52, sleeve assembly 50s with respect to the axis of pivot 12 via its external surface 70c comprising an appropriate profile, for example a stepped profile as shown, so as to fit the diameter of the sleeve being centered.
