The invention relates to a computer-implemented method for providing a holding splint for holding one or more restoration forms. The holding splint is configured for being arranged in a patient's oral cavity on a set of teeth comprising one or more teeth to be restored. The holding splint comprises one or more holding sections configured to hold the one or more restoration forms in order to shape restoration material applied onto one or more surfaces of the one or more teeth to be restored into a predefined form using the one or more restoration forms.

Apparatus comprising: a holder for receiving a mouldable element and for insertion into a user's mouth to allow the user to apply a biting force to the mouldable element to provide close adaptation to the user's teeth, the holder comprising: opposed sidewalls extending from a base, wherein at least one of the opposed sidewalls is configured to move inwards when the user applies a biting force to the mouldable element received by the holder.

A dental impression tray device for taking a dental impression is provided. The dental impression tray device includes a dental impression tray main body and a handle bar connected to the dental impression tray main body. The dental impression tray main body includes a cavity which is formed by an outer curvature wall surface and a base surface. The outer curvature wall surface includes a first finger rest and a second finger rest positioned in a first symmetrical half and a second symmetrical half, respectively, of the dental impression tray device. Each of the first finger rest and the second finger rest has a flat surface shaped as a semi ellipse which has a height less than half of a diameter thereof. Further, the semi ellipse is positioned at a first angle with respect to a line of symmetry.

A finger rest clip, a method of using a finger rest clip and a system for taking an impression of a tooth structure are described, the finger rest clip including an attachment portion which fits over a flange of a dental impression tray and a finger rest portion which extends outwardly from the flange at an angle. The finger rest is designed to prevent the fingers a dentist from being bitten as the dental impression tray is positioned in the mouth of a patient. Two or more finger rest clips are used on the dental impression tray in opposing positions on the flange to enable balanced positioning. The finger rest clips have an attachment part which conforms to the shape of the flange, and may have gripping features. The attachment part and/or the finger rest may be covered with a hydrophilic coating or a biocompatible coating.

The invention relates to a method for producing an individualized dental impression tray and to one such impression tray, wherein a digital impression tray model of an individualized impression tray is created on the basis of a digital jaw model, the impression tray model has a carrier with at least one inner surface which at least partially corresponds to a negative form of the jaw model, at least one surface subregion on the inner surface is marked by hand or automatically detected, a retaining structure is arranged above and/or below the surface subregion, the impression tray model is stored with the retaining structure as a production template, and the impression tray is produced by machining according to the production template. The retaining structure has a first surface which extends substantially parallel to the surface subregion or substantially in line with the surface subregion and has at least one recess running through it, wherein a depression adjoins each recess of the first surface, the depression extends from the recess in the direction of the carrier and/or into the carrier, and each depression has at least one undercut.

Provided is a reference denture alignment jig which guides reference dentures into an oral cavity or to an articulator in which upper and lower edentulous jaw models are fixed, and aligns the reference dentures in the oral cavity or in the articulator in which upper and lower edentulous jaw models are fixed, the jig having a reference denture holding portion for holding reference dentures.

An assembly type rod for an occlusal plane taking is presented. An assembly type rod according to one embodiment comprises: a bite rod of which the middle portion thereof is placed between the upper and lower anterior teeth of a patient to obtain information of the frontal occlusal plane parallel to the interpupillary line; and an extension portion which is coupled to the bite rod in the form of a ball-and-socket through a ball-shaped coupling portion and is rotatable in a state of being coupled with the bite rod such that information of a lateral occlusal plane according to Camper's line on both sides can be acquired.

A blockout putty for use in creating smooth finished molds, such as for use in creating a stone, gypsum, plaster, or other type cast of an impression such as, but not limited to, dental impressions of teeth and/or gums. The putty may comprise a first stage material, diluent, and lubricant. The first stage material may comprise: 0.10 to 30% by weight non-crosslinked polar polymeric resin; 1.25 to 75% by weight filler; 0.0125 to 7% by weight thickening agent; 0 to 45% by weight humectant; and 5 to 85% by weight water. For every 30 to 60 ounces of first stage material, the putty may comprise 4 to 12 fluid ounces of the diluent and 0.5 to 2.75 fluid ounces of the lubricant. The putty may further comprise dye, scent, antibacterial/antiviral/antimicrobial inhibitors, ingredients to control odor, and/or surface disinfection technologies.

The present disclosure provides an implant surgery guiding method of guiding a position, direction and depth of a fixture to a dentist by real-time images. The implant surgery guiding method includes: (a) generating a 3D oral cavity image for a patient; (b) designing a target placement including a target position and a target orientation of a fixture based in the 3D oral cavity image; (c) attaching an oral marker comprising a first pattern to a jawbone or a surrounding body portion of the patient, determining a spatial relationship between the oral marker and the jawbone, attaching a handpiece marker comprising a second pattern on a handpiece of a dentist, and determining a spatial relationship between the handpiece marker and the handpiece; and (d) estimating positions and orientations of the jawbone and the handpiece based on changes in positions and orientations of the oral marker and the handpiece marker while tracking the motions of the oral marker and the handpiece marker, and displaying a jawbone image portion and a handpiece image portion on a screen reflecting real-time changes in the positions and orientations of the jawbone and the handpiece.
