A dental instrument is described. The dental instrument includes a shaft including a graspable end and a usable end. The dental instrument also includes a splatter shield. The splatter shield comprises a pliable sheet material having within the sheet material an aperture formed therethrough. The aperture is sized and shaped in a way to be frictionally and selectively coupled to the usable end of the shaft of the dental instrument.

Methods, apparatus, and systems for reducing transmission of aerosol droplets in a medical or dental procedure are described. In one example aspect, a protective shield system comprises a base plate with a first cover and a second cover. The first cover and the second cover are configured to form at least part of a pipe system when coupled together. The pipe system includes two ducts and an interface configured to be connected to a vacuum suction system. The protective shield system includes two suction tubes removably coupled to the two ducts of the pipe system and a shield having at least one transparent section. The shield configured to be removably coupled to the base plate so as to allow attachment of the shield to the base plate prior to the medical or dental procedure and removal of the shield from the base plate after the medical or dental procedure.

Disclosed is a denture tray for visual marking and a manufacturing method thereof. The method comprises: establishing a three-dimensional model of a target dentition of a target patient; obtaining a three-dimensional model of a substrate of a denture tray based on the three-dimensional model of the target dentition; providing a through hole at a preset position on the three-dimensional model of the substrate of the denture tray; establishing a three-dimensional model of a fixed connection portion on an outer side surface of the three-dimensional model of the substrate of the denture tray to form a three-dimensional model of the denture tray, wherein the three-dimensional model of the fixed connection portion is integrally connected with the three-dimensional model of the substrate of the denture tray; and manufacturing the denture tray based on the three-dimensional model of the denture tray.

A vacuum film (100) for scanning an oral cavity (101), having a perforation layer (103); a fiber layer (105) arranged on the perforation layer (103); and a texture layer (107) arranged on the fiber layer (105).

Disclosed is a multi-functional visual electric toothbrush, including a main unit, an oral viewer, an interdental cleaning appliance and an electric toothbrush head. The oral viewer is connected to the main unit, the interdental cleaning appliance is connected to the front end of the oral viewer, and the electric toothbrush head is connected to a toothbrush driving mechanism. A circuit system and a control system of the main unit can not only transfer the energy of a power supply to the toothbrush driving mechanism, so as to drive the electric toothbrush head to work for large-area oral cleaning, but also connect a lighting system, an observation system and a switch of the oral viewer to control the oral viewer to work. The interdental cleaning appliance may be used cooperatively with the oral viewer to perform targeted cleaning on difficult-to-clean food debris in an oral cavity.

The invention is an assortment of apparatuses to magnetically tether a dental hygienist's hand to the utility tubes and hoses commonly found in a dental office. In a preferred embodiment, this is a ring containing a magnet which is worn by the hygienist. This tethers him or her finger to a utility hose or tube, which has a clasp that contains a reciprocal magnet. In another embodiment, the invention is a finger hold which contains a magnet that tether to the utility hose or tube via the magnetized clasp.

There is disclosed a dental device configured to be coupled to a vacuum. In at least one embodiment the device comprises at least one channel coupled to the vacuum and in fluid communication with the vacuum. In addition, there can be at least one hood coupled to the channel, and covering the channel wherein the hood is in fluid communication with said at least one channel. In addition, there can be at least one clip coupled to the hood. Furthermore, said at least one clip extending substantially perpendicularly to said at least one hood and substantially parallel to said at least one channel, wherein the vacuum is configured to create a negative pressure inside of said at least one hood, and wherein said at least one clip is configured to couple to a user's mouth, wherein said hood is positioned adjacent to a user's mouth.
