To accurately acquire an image of an inside of an oral cavity of a person to be treated, there is provided a dental retractor including a retracting base portion that includes an inner retracting portion extending in an arch-shaped profile to surround an inner portion of gum at any one side of an upper jaw and a lower jaw inside an oral cavity and having a pressing holding portion formed at an outer peripheral surface so that a tongue is accommodated therein and an outer retracting portion integrally extending from both ends of the inner retracting portion and extending in an arch-shaped profile to surround an outer portion of the gum, and a handle portion including a grip portion connected outward from the retracting base portion.

An aqueous high-viscosity gingival hemostatic retraction paste includes greater than 45% by weight kaolin clay, greater than 20% by weight aluminum chloride hexahydrate, and less than 25% by weight water. The paste may also include a thickening agent. The paste may include thickening agent in an amount of between approximately 0.25% and 1% by weight. The paste may also include a desensitizer. The paste may include desensitizer in an amount between approximately 0.5% and approximately 5% by weight. A compression cap for application to a prepared tooth during a gingival retraction procedure includes a body having a first end with an opening and defining a hollowed-out center extending into the body from the opening, wherein the compression cap comprises a wax compound. A method for applying desensitizer to a prepared tooth during a gingival retraction procedure includes applying a desensitizer compound to an inner surface of the compression cap.

The invention relates to a curable dental retraction composition comprising alginate and a solvent, with the proviso that essentially no crosslinker in an amount effective to start setting of the curable dental retraction composition is present. The invention also relates to a container containing said composition and to a kit comprising two parts, wherein the first part comprises the curable dental retraction composition of the present invention and the second part comprises a crosslinker being able to start setting of the dental retraction composition.

Provided is a rolled retraction cord, which has flexibility and is made of a sheet rolled into a non-firm multilayer strip. The sheet has a first side edge and a second side edge, the first side edge and the second side edge are opposite and parallel to each other, and the rolled retraction cord is formed by rolling the first side edge of the sheet toward the second side edge of the sheet. Further provided is a method for manufacturing the rolled retraction cord.

A custom tool for forming a dental restoration in a mouth of a patient includes a one-piece mold body providing for a customized fit with at least one tooth of the patient, the one-piece mold body including an occlusal portion forming an occlusal surface corresponding with an occlusal surface of the tooth, a mesial proximal portion forming a mesial proximal surface corresponding with a mesial proximal surface of the tooth, and a distal proximal portion forming a distal proximal surface corresponding with a distal proximal surface of the tooth. The mold body is configured to combine with the tooth of the patient to form a mold cavity encompassing missing tooth structure of the tooth. The occlusal portion, the mesial proximal portion, and the distal proximal portion are based on three-dimensional scan data of the mouth of the patient

A dental preparation cuff is used to expose a transition region (preparation margin) between a tooth neck of a prepared tooth and surrounding gums. The preparation cuff has a tooth opening to place on the tooth, having a peripheral wall with a cross-sectionally wedge-shaped, radially inwardly tapering edge region. The preparation cuff is manufactured from a material with a Shore hardness in the range between 70A and 95A. This results in a preparation cuff providing improved patient tolerability.

The invention is directed to a process for taking a dental impression and/or conducting a dental retraction, the process comprising the steps of (a) providing a composition (A) having the consistency (a1), composition (A) comprising curable components, and a catalyst suitable to initiate or catalyze the curing of the curable components, composition (A) being contained in a device, (b) applying a portion (I) of composition (A) with a consistency (a2) into the sulcus of a tooth, (c) applying a portion (II) of composition (A) with a consistency (a1) in contact with composition (A) applied in step (b), (d) removing portion (I) together with portion (II) of composition (A) from the surface of the tooth, consistency (a2) being higher than consistency (a1).

A gingival retraction cord using microfiber includes a microfiber cord, which is knitted with a plurality of microfiber strands, of 83 to 95 wt %, a dye of 0.01 to 0.10 wt % for dyeing the microfiber cord, and hemostatic agent of 4.9916.99 wt % which is soaked into the microfiber cord. A thickness of the microfiber cord is 0.45 to 1.35 mm. The microfine cord is classified into a green microfiber cord, a brown microfiber cord, a purple microfiber cord, a blue microfiber cord, and an orange microfiber cord, depending on thicknesses of the microfiber cords, and the microfiber cords are dyed by using dyes.

A dental instrument having a working end that can be easily rotated into a desired position in the mouth of a patient while the handle of the instrument is held in place by the user. The dental instrument has a handle and a working end that is rotatably coupled to handle by a rotational joint formed by a housing having a cavity and a member positioned in the cavity so that the housing and the member are free to rotate relative to each other. The housing may include one or more finger rests for easily manipulation. The rotational joint may be connected to the handle via a bend so that the working end extends obliquely relative to the handle. The working end may a cord packer, a Woodson end, a periotome end, and a periosteal end and the instrument may be formed from an autoclavable material disposable or plastic or other medical grade material.

A custom tool for forming a dental restoration in a mouth of a patient includes a one-piece mold body providing for a customized fit with at least one tooth of the patient, the one-piece mold body including an occlusal portion forming an occlusal surface corresponding with an occlusal surface of the tooth, a mesial proximal portion forming a mesial proximal surface corresponding with a mesial proximal surface of the tooth, and a distal proximal portion forming a distal proximal surface corresponding with a distal proximal surface of the tooth. The mold body is configured to combine with the tooth of the patient to form a mold cavity encompassing missing tooth structure of the tooth. The occlusal portion, the mesial proximal portion, and the distal proximal portion are based on three-dimensional scan data of the mouth of the patient.
