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.

Hygiene regulations and social distancing are very effective in blocking short distance infections. During the lockdown, the distance rules can usually be adhered to, but what happens when the actual lockdown is over and the people meet again in a confined space? Then additional effective and efficient protection is essential to stabilize infection rates. Since the viruses are spread by contact and droplet infection, technical devices are required that effectively intervene in the chain of infection and effectively block infection. An effective protection is the respiratory mask as known since 100 years. An alternative to mask is an aerosol protection system for various applications in environment. The protection system consists of adjustable air sucking device and air blowing device in different form factors based on application. The aerosol protection system uses either an air curtain or air shield to prevent the aerosol going from one side of the curtain or shield to the other side.

A contaminate shield for protecting dentists and patients from harmful emissions during dental procedures is disclosed. The contaminate shield can include apertures allowing the dentist to access the patient's mouth through the contaminate shield. Further, the contaminate shield can include an aperture connectable to an air exchange system that provides clean air to the patient or removes contaminated air expelled by the patient. Additionally, the contaminate shield can be secured to the patient's face such that it covers the patient's nose and mouth to provide a physical barrier between the patient and a dentist.

The present disclosure relates to a patient anxiety management system for managing patient anxiety during a dental procedure. In one example, a patient anxiety management system is presented. The patient anxiety management system includes a control module that a patient can use to disactivate a medical device used by a dental professional by way of a trigger mechanism. Upon deactivating the medical device, a recording device, in communication with the control module, plays a recorded message to the patient during a programmable timeframe. Once the patient is calm, the system resets the medical device to an initial operation state by reconnecting but not reactivating the medical device so that the dental professional may resume the procedure when it is safe to proceed.

A dental aerosol protection system for controlling dispersion of aerosol and splatter particles produced during dental procedures, the system including a ring assembly, a support mask for supporting the ring assembly on a patient, and a suction generating device, the ring assembly and support mask having suction ports which are connectable to the suction generating device to provide a negative suction force around the oral cavity, wherein the ring assembly and support mask can be connected or used separately to control dispersion of aerosols depending upon the requirements of the dental procedure, and one or more flexible extensions connectable to the ring assembly and support mask extending superiorly away from the patient around and over the oral cavity, the flexible extensions forming an adjustable physical barrier between the dental professional and the patient's oral cavity.

The invention relates to a method for the repeated activation of orthodontic correction devices with a known critical temperature (Tkrit) and a glass transition temperature (Tg) lying above the critical temperature. In the method according to the invention, in order to guarantee gentle repeated activation, an orthodontic correction device is heated to a temperature that lies above the critical temperature but below the known glass transition temperature. The invention also relates to a device for performing the method.

The present invention relates to an fastening system (100) for a dental object, comprising a transverse connector (101) for passing through an interdental space (103); and a support member (105) for supporting the transverse connector (101) against the teeth (107-1, 107-2) laterally of the interdental space (103).
