DETAILED DESCRIPTIONS OF THE EMBODIMENTS

[0072] FIG. 1A illustrates a qube having a size, shape and color that has been selected in accordance with a specific use and function during an oral surgery in accordance with an example embodiment.

[0073] FIG. 1B illustrates three qubes having different sizes and shapes selected, and optionally cut from, a larger qube, such as that illustrated at FIG. 1A, each for a specific intended use during an oral surgery in accordance with example embodiments. Several qubes of each of several types, shapes, sizes, and compositions are illustrated and described in example embodiments herein.

[0074] In some example embodiments, a qube may relate to an article for application to human and animal teeth and human and animal dental implants as a medicated and non-medicated space maintainer and/or retraction medium (referred to herein as a QUBE, a Qube, or a qube). A Qube may include, in an example embodiment, a synthetic sponge-like material with a 1) specific porosity size 2) which is autoclavable 3) which can be colored 4) which can be used a vehicle to carry a medicament 1.2% Chlorohexidine, 5) which can be used a vehicle to carry a medicament Calcium hydroxide Ca(OH), 6)which can be used a vehicle to carry a medicament Povodine-Iodine solution, 7) which can be used a vehicle to carry a medicament 2% Iodine Potassium Iodide, 8) which can be used a vehicle to carry a Sterile saline. The Qube is to be applied as an interappointment dressing for endodontically treated teeth in the access cavity to serve as a barrier from microbial invasion of the canal space as well as a mechanism to prevent damage to surrounding tooth structure when a dentist reaccesses the tooth for permanent restoration. The Qube can also be used as a barrier from microbial invasion within the internal aspect of the coronal access of screw retained dental implants.

[0075] The Qube can also be used as a retraction medium for gingival flaps during dental surgery. The Qube can be contoured in specific shapes. The Qube can be impregnated with barium sulfate so it can be visible radiographically. The Qube can be inserted and compacted against gingival soft tissue to allow for atraumatic retraction.

[0076] FIGS. 2A-2G illustrate examples of qubes for use in various roles during oral surgical procedures, including as dental implant spacer qubes at FIG. 2A, and as grafting qubes in FIG. 2B, and as exo socket medicated qubes as in FIG. 2C, and as tapered endoQubes in FIGS. 2D-2G.

[0077] FIGS. 2A-2C illustrate multiple examples of each of three different qube types, including implant cubes, grafting qubes and endo-socket medicated qubes in accordance with example embodiments.

[0078] FIG. 2D-2G illustrates multiple examples of a fourth qube type, including tapered endo qubes in accordance with example embodiments.

[0079] The tapered shape of the wedge shaped qube of FIG. 3 renders it advantageous for insertion into a dental implant space reserved for coupling with an abutment component or an abutment space reserved for coupling with a crown component for a duration of an osseointegration of the implant. The wedge of FIG. 3 has four long sides and a square or rectangular base. Two long sides are parallel, tapered and/or triangularly-shaped and the other two sides are rectangular and form an acute angle at the tapered end.

[0080] One or both of the rectangular long sides may also be tapered or be triangularly-shaped, and a pyramidal qube or tetrahedral qube or truncated pyramid or truncated tetrahedron or cone-shaped, four or five sided pyramid, or pentagonal cone, pentagonal pyramid, truncated cone, half ellipsoid or partial ellipsoid or truncated ellipsoid. One or more of the long sides of a regular rectangular box, cube or polyhedron may be tapered or compressed spatially at one end.

[0081] An implant qube may be more densely-weighted at a tapered end, which may taper to a point or may round off or may be truncated such that a plane at a tapered end may be parallel to a base plane of greater area of a truncated implant qube, which may have small and large diameter circular end planes, or an elongated end plane quadrilateral having at least one short dimension which may taper to a point in one or both cross-plane dimensions.

[0082] FIGS. 4A-4F illustrate seven types of qubes in accordance with example embodiments. Different qubes may have different physical, chemical or biological properties, different functions, different uses, different roles to play within oral surgical applications, different compositions (polymer units or polymer side chains, molecular component monomers or side chains, monomer units or monomer side groups, different sizes (millimeters to centimeters) and shapes (spheres, ellipsoids, cubes, polyhedrons with four to twenty-four sides, wedges, pyramids, tetrahedrons, tapered polyhedrons, truncated polyhedrons, ovoid) and being grouped according to anticipated, intended or scheduled uses, functions, or specific applications among multiple example oral surgical applications in accordance with example embodiments.

[0083] Other qube types may include qubes having different colors or color distributions or different weights, or different overall weight densities (10 kg/m3, 15 kg/m3, 20 kg/m3, 25 kg/m3, 30 kg/m3, 35 kg/m3, 40 kg/m3), or different weight or weight density distributions (20&30 kg/m3, or different porosities, autoclavabilities (thermal: 250 F-300 F, 225 F-325 F, 200 F-275 F, 200 F-280 F, 270 F-280 F, 275 F-300 F, 275 F-325 F; pressure: 20 psi-30 psi, 25-35 psi, 25-30 psi, 23-28 psi, 24=27 psi, 28-36 psi, 24-38 psi)-indentation force deflection (IFD) capabilities, cell openness, cell densities (15-16 cells/cm, 10-20 cells/cm, medicament chemistry (calcium hydroxide CaOH, barium sulfide BaS, titanium dioxide TiO2, silver nitride Ag3N, silver nitrate AgNO3, silver ion Ag+, silver ion Ag−, 1.2% chlorohexidine, povodine-iodine 2% iodine potassium iodide, sterile saline), or medicament biology (bacteriocidal, medicament combinational process types (e.g., soaking, coating, encapsulating, embedding, integrating, release rate).

[0084] FIGS. 5A-5G illustrates a qube placement tool having smooth, blunt appendages for placement of a qube for retraction, or for spacing, cushioning, bandaging, or protecting gum tissue around a bone graft site, tooth extraction site or other oral surgical site in accordance with an embodiment. The blunt appendages of the qube placement tool may be fixed or may be movable towards or away from each other at one end. Examples include plyers without sharp edges or forks with two or more prongs having rounded ends.

[0085] FIGS. 6A-6F illustrates a qube removal tool having sharp, jagged and/or barbed appendages for removing a qube from an oral surgical retraction site, or from a dental implant, or following use during oral surgery cushioning, bandaging, and/or protecting gum tissue at a bone graft site, a tooth extraction site, a dental implant site, or another oral surgical site in accordance with embodiments. An example qube removal tool may articulate such that the barbed ends of two appendages may be safely enclosed or sheathed or enfolded or interlocked in a “safety-on” position and may be actuated or articulated into a “safety-off” position such as to emerge to grab a qube for removal from a retraction site, or a space maintaining site or a tissue protection side or from a dental implant site or other oral surgical qube use site.

[0086] FIGS. 7A-7G illustrate a qube placement and/or removal tool that may have articulated arms or articulated ends or both for, respectively, pushing, maneuvering, reorienting or bluntly pinching or holding a qube for placement at an oral surgical site as a qube placement tool and/or for grabbing, entangling or adhering to a qube to remove it from an oral surgical site as a qube removal tool.

[0087] The photographs of FIGS. 8A-8I illustrate certain steps in a process leading incrementally to completion of the coupling of a dental implant at a site of tooth extraction, tooth absence, tooth loss or tooth decay. Advantageously, only minimal tissue trauma was caused by use of the qube.

[0088] Moreover, in certain example embodiments, use of a qube during an oral surgery or during a step or subset of steps of an oral surgery, e.g., a dental implant surgery, a tooth or jawbone grafting surgery, or another oral surgery involving one or more retraction uses of one or more cubes. In example embodiments, a dental impression may be made, formed, generated or located such as to make a dental impression for molding a synthetic tooth, a grown organic tooth or a tooth graft or set of teeth to replace a tooth or teeth that may have become decayed or that may be colliding with another tooth or gum, cheek, tongue or lip area causing pain or that may be rooted unevenly within an upper or lower jaw in the front or back of the mouth or may have fallen out such that a synthetic replacement tooth or a grown organic replacement dental implant or similar oral constituent may be desired to take its place.

[0089] Example embodiments are provided herein that may involve one or more oral surgical steps, sequences of two or more steps, subsets of multiple steps or several steps, or complete oral surgical processes that involve use of a qube for retraction, maintaining space above or within a dental implant, abutment or crown, or providing temporary structural integrity support for a tooth, gum, dentin, pulp, root, enamel, bone-cementum, crown or combinations or component parts thereof, or for catching, filtering, redirecting, accumulating, or stabilizing or controlling flow rate, area coverage or contained volume density of bodily fluids, saliva, blood, mucous, water, partly digested food or dislodged food fragments or combinations or evolving quantities or components thereof during an oral surgery.

[0090] Example embodiments may advantageously further involve reduced pain, reduced swelling, and reduced tearing, scratching, slicing, stabbing or poking by sharp edges or jagged components of dental instruments, and reduced time to heal and enhanced effectiveness by placement and use of one or more qubes for protecting, cushioning, deflecting, bandaging, or covering one or more exposed, wounded, inflamed or otherwise sensitive areas within a patient's mouth during an oral surgery.

[0091] Example embodiments of dental processes, both surgical and non-surgical, advantageously include sequences of steps involving use of one or more qubes for retraction, maintaining space, cushioning, absorbing, softening, providing flexibility, strength without rigidity, and cohesiveness. After any of a wide variety of oral surgical steps, and in various orders and sequences of oral surgical steps, use of qubes throughout the surgical processes characteristically maintains an availability of choices of next steps, when to stop, how to provide a first dental care process and transition to a different oral state prepared to provide a second dental care process, while continuously, discretely, periodically and/or increasingly having an ability to return, and/or returning, suturing or positioning or orienting tissue to an original position or orientation due to no distortion or damage being caused by this retraction method involving use of a qube rather than a conventional retraction cord or other conventional retraction device or component.

[0092] FIG. 8A includes a photograph that illustrates an incision site reflected in a mirror in accordance with an example embodiment.

[0093] FIG. 8B includes a photograph of a retraction qube inserted into an underside of a surgical flap for retraction in accordance with an example embodiment.

[0094] FIG. 8C includes a photograph of a qube further inserted under a flap in accordance with an example embodiment.

[0095] FIG. 8D includes a photograph including qubes placed on both sides of an incision to retract a surgical flap and expose underlying bone in accordance with an example embodiment.

[0096] FIG. 8E includes a photograph of a visible qube retracting a flap in accordance with an example embodiment.

[0097] FIG. 8F includes a photograph that illustrates retraction qube allowing access to osteotomy for implant site preparation and better visibility in accordance with an example embodiment. A floor of a maxillary sinus is visible in the photograph of FIG. 8F as the grey circular area in the image. Post-operatively, however, the patient had minimal pain, swelling and inflammation due to use of a qube retraction medium in an advantageous form of retraction during an oral surgery. There was also a strong unobstructed healing response due to lack of trauma during the surgery.

[0098] FIG. 8G includes a photograph wherein the retraction qube of FIG. 8F has been removed in accordance with an example embodiment.

[0099] FIG. 8H includes a photograph of a qube removed from an opposite side of an implant in place below a gingival surface in accordance with an example embodiment.

[0100] FIG. 8I includes a photograph of a surgical flap closed and sutured around a dental implant site in accordance with an example embodiment. In fact, a pair of surgical flaps are shown sutured in place on opposite sides of a dental implant site that includes an abutment component coupled to a dental implant that is secured to the jawbone of a dental customer or orthodontal patient. A crown may be next coupled to the abutment component of the example embodiment that is illustrated photographically at FIG. 8I.

[0101] FIGS. 9A-9U illustrate photographically examples of endocubes and/or dental implant cubes in accordance with example embodiments.

[0102] FIGS. 10A-10I include surgical photographs that include qubes in place and in use during performance of various oral surgical steps. In these example embodiments, the Qube material exhibits advantageous usefulness and functionality as a demonstrably suitable retraction medium.

[0103] FIGS. 10A-10I are photographs illustrating multiple uses of qubes of different sizes and shapes specifically configured for a planned use during one or more scheduled oral surgeries in accordance with example embodiments. FIGS. 10A-10H include multiple photographs that include one or more qubes each in place performing a retraction function. Other uses of qubes include performing a spacer or space-maintaining function during an oral surgical procedure that includes two or more subsets of an overall surgery or of a complete procedure, such as between coupling a dental implant at a grafted or ungrafted jawbone socket site which has become decoupled from a tooth suddenly or gradually over time, or a jawbone site that is at risk of becoming decayed unless a rotting tooth is extracted or repaired.

[0104] The two or more subsets of sequential oral surgical steps, processes, actions or modifications may, in one example embodiment, be spaced apart in time. In an example embodiment, a time delay advantageously allows for sufficient osseointegration of a bone graft within a jawbone socket, or socket graft, for example, prior to a dental implant procedure. Such a dental implant procedure may itself follow a sudden, unexpected tooth loss collision event or a long and steady incremental tooth decay process, or an ordinary tooth extraction, or a drawn-out, crumbling tooth disintegration lasting perhaps years or another tooth and/or jawbone volume reducing event.

[0105] The two or more surgical process subsets may, in another example embodiment, be spaced apart in time in order to allow sufficient osseointegration of a dental implant inserted within a jawbone socket at a depth below a gingival margin anywhere in a range between a shallow implant coupling location through an average implant depth location to a deep implant coupling location that may be significantly below a gingival margin. In this example embodiment, a second surgical process subset may involve coupling within a dental implant component for maintaining a space for attaching an abutment after sufficient osseointegration of the implant has occurred over the passage of time.

[0106] FIGS. 10A-10H include surgical photographs that include qubes in place and in use during performance of various oral surgical steps. In these example embodiments, the Qube material exhibits advantageous usefulness and functionality as a demonstrably suitable retraction medium.

[0107] FIGS. 11A-11K illustrate example embodiments of example retraction steps and example retraction qubes useful in multiple roles during a dental implant procedure involving a screw-coupled dental implant in accordance with example embodiments.

[0108] FIGS. 12A-12J illustrate example embodiments of example retraction steps and example retraction qubes useful in multiple roles during a dental implant procedure involving a cement-coupled dental implant in accordance with example embodiments.

[0109] FIGS. 13A-13G photographically illustrate further example qube uses and applications and example qubes. One or more qubes may be used to retract a rubber dam. A qube may be used to retract soft tissue as well. A qube may be used to protect cheek tissue, tongue tissue, lip tissue, gum tissue, tonsil tissue, and/or tissue at the roof of the mouth or under the tongue from a surgical drill or other surgical instruments. A qube may protect tissues of the mouth from encountering tooth or implant fragments which may have sharp or jagged edges by adhering, blocking or deflecting such items.

[0110] FIG. 14A-14T illustrate photographically an example procedure using retraction qubes in accordance with another embodiment.

[0111] FIG. 15A schematically illustrates a decayed tooth 1512, which may also be a deformed tooth, a misplaced tooth, a misoriented tooth, a pain-producing tooth, an outsized molar or an otherwise unwanted tooth 1512, which is located between a pair of healthy teeth 1511, 1513, and which is prior to extraction of the decayed tooth 1512, or prior to a collisional tooth loss, a disintegrational or naturally decaying tooth loss, or another unintended tooth loss, in accordance with example embodiments.
