Dental stabilization blocks, systems and methods

Abstract

One of the objects of the present invention is to provide a dental stabilization device, which prevents the patient from easily releasing the teeth from the device during dental procedures. For this purpose, the inventor proposes a dental stabilization block with an internal channel that opens on the face of the dental stabilization block that contacts the patient's teeth. The internal channel is connected to an inlet through which a bite registration material can be injected, which hardens and molds to the patient's teeth. In this way, it becomes more difficult for the patient to release the teeth from the dental stabilization block when the bite registration material hardens and molds around the teeth.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0023] Description of the embodiments SUMMARY OF THE PRESENT EMBODIMENTS One object of the present invention is to provide a dental stabilization device that prevents a patient from easily removing his or her mouth from the device during a dental procedure.

[0024] For this reason, the inventor proposes a dental stabilization block that is provided with internal channels that open on the face of the dental stabilization block that is in contact with the patient's teeth, these internal channels being connected to inlets through which a bite registration material can be injected that hardens and molds to the patient's teeth.

[0025] In this manner, once the bite registration material has hardened and molded around the teeth, it becomes more difficult for the patient to separate the teeth from the stabilizing block.

[0026] Thus, as shown in FIG. 1, the present invention is directed to a dental stabilization block 100 .

[0027] In practice, the dental stabilization block 100 is intended to be bitten on only one side of the oral cavity, between the patient's upper and lower molars and / or premolars (hereinafter referred to as "teeth").

[0028] That is, when the dental stabilization block 100 is in place in the patient's mouth, the patient can bite down on the dental stabilization block 100 with only the upper and lower molars, or only the upper and lower premolars, or with both the upper and lower molars and the upper and lower premolars.

[0029] In a preferred embodiment of the present invention, different sizes of dental stabilization blocks 100 can be provided depending on the patient's dental morphology, i.e. the arrangement of the teeth in the upper and lower jaws.

[0030] For example, a child model and an adult model may be provided.

[0031] However, other arrangements may be considered depending on the needs and taking into account the patient's dental morphology without requiring significant modification of the present invention.

[0032] FIG. 2 shows the dental stabilization block 100 when placed on the lower teeth located on the left side of a patient's mouth.

[0033] In effect, the dental stabilization block 100 allows the patient's mouth to be kept open during a dental procedure to prevent the teeth from meeting.

[0034] In this manner, the dental stabilization block 100 allows access to the teeth and gums located on the opposite side and the front of the oral cavity without being significantly obstructed by the dental stabilization block 100 .

[0035] That is, when the dental stabilization block 100 is in place in the patient's oral cavity, the practitioner performing the dental procedure can access not only the teeth and gums in the anterior portion of the oral cavity, but also the portion of the oral cavity that is opposite the position of the dental stabilization block 100.

[0036] Thus, in the first example, when the dental stabilization block 100 is placed on the teeth located on the right side of the patient's oral cavity, the practitioner can access the teeth and gums located at the front of the oral cavity, as well as the teeth located on the left side of the oral cavity.

[0037] Similarly, in the second embodiment, when the dental stabilization block 100 is placed on the teeth located on the left side of the patient's oral cavity, the practitioner can also access the teeth and gums located on the front of the oral cavity as well as the teeth located on the right side of the oral cavity.

[0038] Returning to the present invention, the dental stabilization block 100 comprises a body 110 having a generally parallelepiped shape.

[0039] The body 110 therefore has the shape of a parallelepiped, ie a six-sided polyhedron whose six faces are pairwise parallel.

[0040] In practice, the shape of the body 110 is substantially curved to correspond to the approximate curve of the upper and lower teeth of the human jaw.

[0041] In particular, as shown in Figures 1, 3, 7 and 9, when the dental stabilization block 100 is placed in the patient's oral cavity, the body 110 has an upper wall 111, a lower wall 112, a first side wall 113, a second side wall 114, a front end wall 115 and a rear end wall 116.

[0042] In practice, the upper wall 111 has an upper outer fastening surface designed to contact the upper teeth.

[0043] As shown in FIGS. 1, 3, 4, 5, 6, 7 and 9, in one particular embodiment of the upper outer fastening surface, the upper outer fastening surface comprises an upper peripheral rim 1111.

[0044] In particular, the upper peripheral rim 1111 is configured to hold bite registration material, as described below.

[0045] In one particular embodiment of the upper outer fastening surface shown in FIGS. 1, 3, 4, 5, 6, 7 and 9, the latter comprises a plurality of fluid flow disruption ribs 1112.

[0046] In practice, each fluid flow disrupting rib 1112 is configured to cause a disruption in the flow of fluid passing over the upper outer clamping surface when the dental stabilization block 100 is in place in a patient's mouth.

[0047] In a first example of this particular embodiment, the fluid flow disruption ribs 1112 extend upwardly from the upper outer fastening surface.

[0048] In a second example of this particular embodiment, the fluid flow disruption ribs 1112 extend through the fluid flow axis of the upper outer fastening surface.

[0049] In a third example of this particular embodiment, the fluid flow disruption ribs 1112 have an upper outer turbulence surface selected from a stepped surface, a raised surface, a recessed surface, or a roughened surface.

[0050] Additionally, as shown in FIGS. 1, 3, 4 and 5, the upper outer clamping surface includes at least a first exit orifice 1113 .

[0051] In one particular embodiment of the first exit orifice 1113, as shown in FIG. 4, the first exit orifice 1113 has a peripheral internal recess 1113a so as to form at least a first peripheral decoupling surface disposed below the upper outer fastening surface.

[0052] Like the upper wall 111, the lower wall 112 also has a lower outer fastening surface designed to contact the lower teeth.

[0053] In one particular embodiment of the lower outer fastening surface, the latter comprises a plurality of fluid flow disrupting ribs similar to the fluid flow disrupting ribs 1112 of the upper outer fastening surface.

[0054] In a first example of this particular embodiment, the fluid flow disruption ribs extend downwardly from the lower outer fastening surface.

[0055] In a second example of this particular embodiment, the fluid flow disruption ribs extend through the fluid flow axis of the lower outer fastening surface.

[0056] In a third example of this particular embodiment, the fluid flow disruption rib has a lower outer turbulence surface selected from a stepped surface, a raised surface, a recessed surface, or a roughened surface.

[0057] Additionally, the lower outer clamping surface includes at least a second exit orifice 1123 .

[0058] As shown in FIG. 5, in one particular embodiment of the second exit orifice 1123, similar to the first exit orifice 1113, the latter is provided with a peripheral internal recess so as to form at least a second peripheral decoupling surface disposed below the lower outer fastening surface.

[0059] As shown in FIG. 2, with reference to FIGS. 1, 3, 4, 5, 6, 7 and 9, when the dental stabilization block 100 is in place in the patient's mouth: The first side wall 113 faces the inside of the oral cavity; The second side wall 114 faces the inner cheek surface, in particular the inner cheek surface located on the side of the oral cavity on which the dental stabilization block 100 is placed. Thus, when the dental stabilization block 100 is placed on the right side of the patient's oral cavity, the second side wall 114 faces the inner surface of the patient's right cheek. Furthermore, when the dental stabilization block 100 is placed on the left side of the patient's oral cavity, the second side wall 114 faces the inner surface of the patient's left cheek. The front end wall 115 faces forward of the oral cavity; The rear end wall 116 faces toward the rear of the oral cavity.

[0060] Additionally, as shown in FIG. 5, the body 110 includes at least a first internal passage 117, at least a second internal passage 118, and a first internal bond region 119.

[0061] In particular, the first internal passage 117 located inside the body 110 opens towards the outside of the body 110 at least at the level of the first outlet orifice 1113 and / or at least at the level of the second outlet orifice 1123 .

[0062] That is, the first internal flow passage 117 can open outward by passing only through the first exit orifice 1113, by passing only through the second exit orifice 1123, or by passing through both the first exit orifice 1113 and the second exit orifice 1123.

[0063] Additionally, the first internal channel 117 defines a flow path configured for the passage of at least a bite registration material intended to harden and mold onto the teeth.

[0064] In a first embodiment of the bite registration material, the bite registration material is selected from wax.

[0065] For example, it is possible to choose from mineral waxes (e.g. alkanes such as paraffin), waxes of natural origin (e.g. esters such as carnauba wax, beeswax), waxes of synthetic origin (e.g. polyethylene waxes, polyethylene glycol waxes, hydrogenated or halogenated hydrocarbon waxes), and any combination thereof.

[0066] In a second embodiment of the bite registration material, the bite registration material is selected from zinc oxide-eugenol paste.

[0067] In a third embodiment of the bite registration material, the bite registration material is selected from addition silicone elastomers.

[0068] In a fourth embodiment of the bite registration material, the bite registration material is selected from polyester elastomers.

[0069] However, if necessary, it is also conceivable to use other dental materials capable of deformation under occlusal stress, to obtain this deformation and then restore it as is, without significantly modifying the invention.

[0070] A second internal passage 118 located inside the body 110 opens towards the outside of the body 110 at the level of an inlet orifice 1131 .

[0071] The entrance orifice 1131 is configured to receive at least one end of a device for injecting bite registration material.

[0072] In one example, the end according to the present invention is a mixing tip of a bite registration material injector of known type.

[0073] In one particular embodiment of the entrance orifice 1131, as shown in Figures 5 and 8, the entrance orifice 1131 comprises a shoulder 1132 against which the end of a device for injecting the bite registration material can abut.

[0074] Further, in the present invention, the inlet orifice 1131 is located on the outer surface of the first side wall 113 and / or the front end wall 115 .

[0075] That is, the inlet orifice 1131 may be located only on the outer surface of the first side wall 113 , or only on the outer surface of the front end wall 115 , or on both the outer surface of the first side wall 113 and the outer surface of the front end wall 115 .

[0076] Finally, first internal bond region 119 is configured to establish fluid communication between first internal flow passage 117 and second internal flow passage 118 .

[0077] Thus, when bite registration material is injected into the entrance orifice 1131 , it can come out at the level of the exit orifices 1113 , 1123 .

[0078] FIG. 5 shows the exit orifices 1113,1123.

[0079] In a first embodiment of the present invention, the body 110 includes a plurality of first internal passages 117 and a plurality of second internal bond regions.

[0080] In practice, the plurality of first internal channels 117 located inside the body 110 are arranged such that in response to injection of the bite registration material, the bite registration material is produced substantially simultaneously at the level of the outlet orifices 1113, 1123.

[0081] Additionally, the plurality of second internal bond regions are arranged such that each second internal bond region establishes fluid communication between at least two of the first internal flow paths 117 .

[0082] That is, each second internal bond region can establish fluid connections between two, three, four, or more than three first internal flow paths 117.

[0083] In a second embodiment of the present invention, the first side wall 113 and the second side wall 114 are designed to extend beyond the upper outer fastening surface and / or the lower outer fastening surface, respectively, toward the top and / or bottom of the oral cavity.

[0084] That is, in a second embodiment of the present invention, the first side wall 113 and the second side wall 114 extend only toward the upper part of the oral cavity, or only toward the lower part of the oral cavity, or toward both the upper and lower parts of the oral cavity.

[0085] This arrangement is such that when the dental stabilization block 100 is in place in the patient's mouth, it can cover the upper and / or lower teeth to form upper and / or lower housings of U-shaped cross section that can hold bite registration material and the upper and / or lower teeth.

[0086] That is, if the first sidewall 113 and the second sidewall 114 extend only toward the upper part of the oral cavity, they form an upper housing. Further, if the first sidewall 113 and the second sidewall 114 extend only toward the lower part of the oral cavity, they form a lower housing. Finally, if the first sidewall 113 and the second sidewall 114 extend toward both the upper and lower parts of the oral cavity, they form an upper housing and a lower housing.

[0087] In particular, as shown in FIG. 6, in the upper housing 1114 and the lower housing, the base of the U-shaped cross section of the upper housing 1114 or the lower housing includes an upper outer fastening surface or a lower outer fastening surface, respectively.

[0088] Furthermore, the wings of the U-shaped cross section of the upper housing 1114 or the lower housing respectively include a first side wall 113 and a second side wall 114 .

[0089] Thus, the upper housing 1114 has a U-shaped cross-section, the base of which includes the upper outer fastening surface and the wings of which include the first 113 and second 114 side walls.

[0090] Furthermore, like the upper housing 1114 , the lower housing also has a U-shaped cross-section, the base of which includes a lower outer fastening surface and the wings of which include a first side wall 113 and a second side wall 114 .

[0091] In one particular embodiment, as shown in FIGS. 1, 3, 4 and 6, the second sidewall 114 extends higher than the first sidewall 113.

[0092] In a third embodiment of the present invention, the second side wall 114 is provided with a cheek retraction 130 for retracting the inner cheek surface of the second side wall 114 .

[0093] As shown particularly in Figures 1, 2, 3, 6, 7, 8 and 9, cheek indentations 130 protrude from second sidewall 114 towards the inner cheek surface.

[0094] Additionally, as shown in FIGS. 7 and 9, when the dental stabilization block 100 is in place in the patient's mouth, the cheek indentation 130 has an L-shape with a rounded bend 131 .

[0095] In practice, as shown in Figs. 7 and 9, one branch portion (hereinafter referred to as the "bearing branch portion") 132 of cheek retraction portion 130 and rounded bent portion 131 are held against the inner cheek surface.

[0096] Furthermore, the other branch (hereinafter referred to as the “cantilever branch”) 133 of cheek retraction portion 130 is cantilevered and is at least partially supported by rear end wall 116 .

[0097] In a first embodiment of the third aspect of implementing the present invention, as shown in FIG. 8, the cheek retraction portion 130 comprises at least a third internal passage 134 that is at least partially disposed inside the rounded bend portion 131.

[0098] In a first embodiment of the third aspect of carrying out the invention, the internal passage 134 is disposed inside the rounded bend 131 and inside the bearing branch 132 .

[0099] In a second embodiment of the first embodiment of the third aspect of carrying out the present invention, the internal flow channel 134 is disposed inside the rounded bend 131 and inside the cantilever branch 133 .

[0100] In a first embodiment of the third aspect for carrying out the present invention, the internal flow passage 134 is disposed inside the rounded bend portion 131, inside the bearing branch portion 132, and inside the cantilever branch portion 133.

[0101] In practice, the third internal passage 134 opens towards the outside of the body of the bearing branch 132 at the level of the suction orifice 1341 and at the level of the discharge orifice 1342 .

[0102] In particular, as shown in FIG. 8, a suction orifice 1341 is disposed on the cantilever branch 133 upstream of the rear end wall 116 relative to the patient's oral cavity.

[0103] Additionally, an outlet orifice 1342 is disposed on the bearing branch 132 downstream of the suction orifice 1341 relative to the patient's oral cavity.

[0104] In one particular embodiment of the first embodiment of the third aspect of the present invention, as shown in FIG. 8, the bearing branch 132 is provided with a suction cannula guide portion 1321 that opens toward the second side wall 114 and extends axially from the discharge orifice 1342 to the free end of the bearing branch 132.

[0105] In a second embodiment of the third aspect of implementing the present invention, as shown in FIG. 9, the dental stabilization block 100 further comprises an extension branch 140 extending obliquely or vertically from the free end of the bearing branch 132 toward the outside of the oral cavity.

[0106] In practice, the extension prong 140 is designed to form a redirection region 141 that presents an outer surface that covers the labial commissure of the oral cavity when the extension prong 140 is deflected out of the patient's oral cavity.

[0107] Furthermore, at least one free end region of the extension branch 140 comprises at least one support element 142, 143 adapted to support at least one position reference element.

[0108] In the present invention, the position reference elements are designed to act as guide elements for a dental surgical navigation system of known type.

[0109] By "dental surgery navigation system" is meant a computer-aided navigation system that allows for providing visual assistance to the practitioner during dental surgery. Although several guidance techniques exist (e.g., by optical or electromagnetic fluoroscopy), the goal is the same, i.e., to provide accurate feedback of the position of the dental stabilization block 100 using medical images.

[0110] In practice, the positional reference element is adapted to trigger registration of one or more dental images associated with the patient based on movements of the patient's head when the positional reference element is moved in response to at least one movement of the patient's head.

[0111] The present invention is also directed to a first dental stabilization system.

[0112] In practice, the first dental stabilization system comprises a dental stabilization block 100 according to the second embodiment of the third aspect of implementing the invention and the position reference element described above.

[0113] In particular, the position reference element is configured to be coupled to at least one support element 142 , 143 in a free end region of the extension branch 140 .

[0114] The present invention is also directed to a second dental stabilization system.

[0115] In practice, the second dental stabilization system comprises two dental stabilization blocks 100 according to any one of the variants of the invention.

[0116] In particular, the two dental stabilization blocks 100 of the second dental stabilization system are configured to be placed on opposite sides of the patient's oral cavity.

[0117] Finally, as shown in FIG. 10, the present invention is directed to a method 200 for dental stabilization during a dental procedure.

[0118] First, the method 200 includes step 210 of placing at least one dental stabilization block 100 according to any one of the variations of the present invention on the patient's upper and lower molars and / or premolars (hereinafter referred to as "teeth") in the patient's oral cavity.

[0119] Next, the method 200 includes the step 220 of introducing into the entrance orifice 1131 the end of an instrument for injecting a bite registration material that hardens and molds to at least the teeth.

[0120] Finally, the method 200 includes the step 230 of injecting a bite registration material into the entrance orifice 1131 .
