Definitions

  • the disclosure relates generally to the field of dental devices and related assemblies and methods.
  • the disclosure relates to molds or matrices for preparing restorations of one or more teeth, and related assemblies and methods.
  • Broken, chipped, small, narrow, or deteriorated teeth may need to be rebuilt or repaired to restore the tooth to its original shape and/or appearance.
  • Restoring a tooth to its original shape may repair the bite of a patient and protect the original tooth.
  • Restoring a tooth may also correct speech problems experienced by the patient due to broken teeth.
  • Restorations may also be utilized to close gaps between adjacent teeth and increase the size of the tooth ( e.g ., the length and/or width of the tooth).
  • a broken tooth may be repaired through a filling process such as composite bonding.
  • a surface of the tooth may be etched to create a retentive surface.
  • An adhesive material may then be applied followed by a resin.
  • the resin is generally hardened using a curing light.
  • a larger repair to an anterior broken tooth may include applying a dental cap or crown.
  • Crowns may be made from metal, porcelain, porcelain fused to metal, or resin, and require preparation to the tooth and removal of tooth structure.
  • a pin or post may be inserted into the root of the tooth, for retention, and a core is built up. The crown or cap may then be cemented to the post and core.
  • a temporary crown will be temporary cemented on the tooth stamp.
  • a permanent indirect crown will be created and secured to prepared tooth stamp at a later time.
  • Another method that may be used to repair a broken tooth or change its morphology is composite resin.
  • a common method to assist in building the missing palatal area is to create a prefabricated silicon stent. First, a mold may be taken from the patient’s teeth. Then a cast model is formed from the mold and a wax-up is shaped for the broken portion of the patient’s tooth. A silicon mold is created from the wax up. The silicon mold is positioned on top, in front, or behind the tooth to be repaired. The dental professional then proceeds to build up the tooth with a resin or composite resin material filling the damaged area between the damaged tooth and the silicon mold.
  • the build-up material may be applied to the silicon stent or into the tooth and cured in stages (e.g ., layers) using a specialized light (e.g, Plasma, LED light). Once the area is filled and light cured, the mold may be removed. Or can be removed after curing the first layer. This is method requires two appointment and involves many steps.

  • the practitioner may use a finger to form the composite rather than a silicon mold.
  • a dental indirect veneer is a thin shell of porcelain or resin composite material that covers the whole front of the broken tooth.
  • the dental veneer generally requires a mold (e.g, impression) of the teeth to be taken to create the veneer.
  • the veneer is generally created in a dental lab. Once the veneer is created, a front surface of the broken tooth may first be etched to provide a rough surface. The veneer may then be applied to the rough front surface of the broken tooth with bonding cement.

  • a difference between the distances between the top portion 112a and the base 102, and the bottom portion 114a and the base 102 may be defined by the angle Q extending between the side structures 116a and the base 102.
  • the angle Q may vary between molds for different types of teeth.
  • the angle Q may define an angle that the palatal side of the tooth extends from the gum line to a lower or incisal portion of the tooth.
  • the dental professional may also adjust the angle of the palatal side of the tooth for different patients by securing the mold 100a with the base at an oblique angle.
  • FIG. 4B illustrates a mold 100b with a saddle 104b having side structures 116b.
  • at least one of the side structures 116b, the top portion 112b, and the bottom portion 114b may define a substantially concave surface curving toward the front portion of the mold 100b configured to be complimentary to a shape of the base or top portion of the tooth.
  • the side structures 116b may define another angle Q or multiple angels, as depicted, at an interface of the side structures 116a and the base 102 extending between the top portion 112a and bottom portion 114a.
  • the angle Q may vary due the contour of the palatal side of the tooth and may define at least a portion of the palatal side of the tooth as it extends from the gum line.
  • FIG. 4C illustrates a mold 100c having side structures 116c defining saddle 104c.
  • the substantially planar side structures 116c may extend at an angle Q with respect to the base 102, where the angle Q is relatively greater than the angle Q of the molds 100a and 110b.
  • FIG. 5 depicts a perspective view of a dental accessory (e.g ., dental tool 200) for manipulating a mold, such as, for example, the mold discussed above.
  • a portion of a mold e.g., the base 102 of mold 100 as shown in FIGS. 1 and 2 may act as an anchoring structure (e.g, connection point) to secure the mold 100 to the dental tool 200 during a procedure.
  • the dental tool 200 may be a handheld tool (e.g, dental tweezers, clamp, combination thereof, etc.).
  • the dental tool 200 may include a body portion 202 that may enable a practitioner to grip and manipulate the dental tool 200 (e.g, via an uneven gripping surface with one or more indents for receiving a portion of the practitioner’s fingers).
  • One end of the dental tool 200 e.g, a first end 204
  • may include a receiving feature e.g, receiving ring 206, for example, at a distal end of a necked portion of the first end 204.
  • the receiving ring 206 may define an aperture 208 in which at least a portion of the base 102 of mold 100 (FIGS. 1 and 2) may be received in order to secure the mold 100 during a dental procedure.
  • an opposing end of the dental tool 200 may include another implement that may be related to, or separate from, the securing of the mold 100 (FIGS. 1 and 2) during the dental procedure.
  • the second end 210 may include another tool (e.g, flanged or angled portion 212, which may function as, for example, an application instrument, a carver instrument, etc.) at a distal end of a necked portion of the second end 210.
  • a flanged or angled portion 212 may be utilized for manipulation and/or finishing of the molded replacement tooth (e.g, once the mold 100 is removed).
  • material e.g, matrix material, such as, for example, cellulose strips, silicon, Teflon®, or any other suitable separation material
  • the matrix material may define a portion of, or an extension of, the side portions or wings 108, 110 of the mold 100.
  • the matrix material may be integral with or separate from ( e.g ., temporarily attached to) the mold 100.
  • the matrix material may be inserted and/or embedded into the mold 100 (e.g., which may comprise a relatively flexible material, such as silicon) where the matrix material may extend from one or more of the mesial or distal sides of the mold 100.
  • the dental practitioner may press the mold 100 and the matrix material (e.g, defining side portion(s) 108, 110) into one or more of the adjacent teeth or the tooth being formed in order to assist in forming a desired gap between the tooth being formed and one or more of the adjacent teeth.
  • Such a configuration may enable the subject to maintain (e.g, floss and/or clean) the tooth after it is formed.
  • Embodiments of the molds, sets of molds, and related systems and methods may provide similar benefits and advantages to restorations, such as crowns, caps, veneers, or other types of restorations without requiring multiple visits to take impressions and verify fitment of custom shaped elements.
  • the embodiments of the molds may enable generic molds to be used when repairing and/or modifying teeth (e.g, to repair a damaged tooth, to modify the size of a tooth, to modify a gap between teeth, to provide a class 3 filing to, for example, repair a cavity between two front teeth, etc.) rather than custom fit elements.
  • Generic molds may decrease the cost of repairs as well as seat time required to make the repair.
  • the molds described herein may be used by pediatric dentists, general dentists, orthodontists, implant surgeons and/or periodontists.
  • Embodiments of the molds, sets of molds, and related systems and methods may enable practitioners to provide more composite fixes and relying less fixes involving crowns and porcelain veneers.
  • the subject’s healthy tooth structure may be retained and utilized in comparison to crowns and porcelain veneers that generally involve the removal or diminishing of such structure.
  • embodiments of the instant disclosure enable the use of advanced composite materials to create a precise replica of the missing part of the tooth and create additive procedure dentistry in a faster and more predictable way.
