An inversion maintenance device has a case, an inverting mechanism, and a control system. The case forms an inversion space. The inverting mechanism has an inverting base and multiple adapting modules. The inverting base is pivotally mounted in the inversion space. The adapting modules are mounted on the inverting base. Each of the adapting modules has an adapting port. The inverting base is capable of inverting to make the adapting port face downward and cover the inversion space. Dental handpieces can be mounted on the adapting modules. The control system has a control module and an operation input terminal. The operation input terminal is electrically connected to the control module and is capable of controlling the control module to inject a working fluid with pressure into the dental handpiece via the adapting module.

A medical, in particular dental-medical, fan for extracting or compressing a gaseous working fluid, in particular air, comprises a compressor unit with an outer housing, which comprises an inlet opening for the working fluid and an outlet opening for the working fluid, which are fluidically connected to one another, and which defines a compressor sector and a drive sector.

A patient safety shield, and its method of use, features a deflector shield that closes gaps between the bottom profile of safety eyewear worn by the patient and the patient's cheek area. The deflector shield, when positioned, oriented, and profiled across the bridge of the patients nose and under the patient's eyewear , deflects fine infectious and or injurious debris, which originates in the patient's oral cavity, from being ejected off moving parts of dental tools during a dental procedure. The deflection by the deflector shield prevents potentially infectious or injurious debris from reaching and harming the eyes of the patient that may enter through the bottom gaps.

The present invention is an improved dental drill and system of assisting patients with anxiety due to dental visits. The Audio Drill system collects data such as music and time for the purposes of receiving audio data packets from a mobile device. Mobile devices such as smart phones, tablets, Internet computers, and other hand-held mobile devices are ideal for submitting music to the proposed invention. The affiliations are determined based upon the audio date and other critical markers. The system may even be enhanced by use of features tailored by the user.

An intraoral imaging system comprising an intraoral adapter. The intraoral adapter may be operably coupled to a mobile device. The intraoral adapter may comprise an elongated housing comprising a viewing channel. The viewing channel may define a field of view of an intraoral region of a subject's mouth for intraoral scanning using a camera of a mobile device. The elongated housing may comprise a flange that is positioned outside of the field of view of the intraoral region of the subject's mouth. The intraoral imaging system may further comprise an image processing unit configured to (i) process a plurality of intraoral images and/or videos captured using the camera of the mobile device, and (ii) determine a dental condition of the subject based at least in part on the plurality of intraoral images and/or videos.

The invention relates to a device for shielding teeth to be treated in order to prevent an inflow of liquid, such as saliva or blood for example, and to a use of the device according to the invention. The invention relates to a partial dental dam (1) for protecting teeth to be treated, comprising a tensioning cloth (2) made of an elastic material and two actuation elements (3) arranged on opposing ends of the tensioning cloth (2). The tensioning cloth (2) is designed to be introduced into at least one intermediate tooth space (11) from the occlusal side in a first tensioned state, which can be achieved by pulling apart the actuation elements (3) in a tensioning direction (90), and to sealingly rest against the interdental gingiva and the approximal surfaces of the teeth (10) forming the at least one intermediate tooth space (11) in a second state after being introduced into the at least one intermediate tooth space (11). Each actuation element (3) rests against at least one tooth (10) and/or against the surrounding gingiva in the second state. The invention further relates to the use of the partial dental dam according to the invention. The tensioning cloth (2) is elongated by pulling the actuation elements (3) in the tensioning direction (90); the tensioning cloth (2) is introduced into at least one intermediate tooth space (11) from the occlusal side in the elongated state; and the tensioning cloth (2) is brought to rest against the interdental gingiva and the approximal surfaces of the teeth (10) forming the at least one intermediate tooth space (11) by releasing the tensioning force. Each of the actuation elements (3) rests against at least one tooth (10) and/or against the surrounding gingiva.
