Aspects of the present disclosure relate to systems, devices and methods for performing a surgical step or surgical procedure with visual guidance using an optical head mounted display. Aspects of the present disclosure relate to systems, devices and methods for displaying, placing, fitting, sizing, selecting, aligning, moving a virtual implant on a physical anatomic structure of a patient and, optionally, modifying or changing the displaying, placing, fitting, sizing, selecting, aligning, moving, for example based on kinematic information.

Medical or dental cleaning and/or care device for cleaning and/or care of at least one instrument, comprising: a housing, a plurality of chambers, each of the plurality of chambers configured to accommodate at least one instrument, wherein each chamber has at least one dispensing element for dispensing at least one cleaning agent and/or care agent into the respective chamber and/or to the instrument accommodated in the respective chamber, an opening in the housing, through which the plurality of chambers can be loaded with instruments, and a cover for closing the opening and the plurality of chambers, wherein only a part of the opening can be closed by the cover so that when at least one of the plurality of chambers is completely closed, at least another one of the plurality of chambers is not completely closed.

The invention relates to a protective device, which in particular prevents a dental surgeon from being contaminated by a patient during dental treatment device.

To be more specific, this protective device comprises: a transparent shield (1); a flexible support (3) connecting the transparent shield (1) to a chair (2), the means for attaching (4,5) the flexible support (3) to the chair (2).

The invention pertains to the use of such a device.

A mixer assembly with a static mixing element arranged within a mixing channel. The mixer assembly has an inlet end, for receiving components of a substance and a dispensing end for dispensing a mixture from the components. The inlet end comprises for each component an inlet and an associated non-return valve. Each of the inlets is connectable for fluid communication with the mixing channel via the associated non-return valve.

An air treatment device having a flexible air hose, duct or gooseneck member. The air hose, duct or gooseneck member permits an inlet end thereof to be positioned in proximity to a patient so that a negative pressure can be created around the patient so that air can sucked or vacuumed into the system whereupon it is treated as the air flows through the system.

A three-dimensional dental device is fabricated in a layer-by-layer approach using a support material. The support material is deposited in a liquid form on a surface, hardened by cooling or ultraviolet (UV) curing, and selectively ablated to create an area within which the desired structure of the dental device will be formed. Active dental material is deposited into this area, and the layer-by-layer process repeated until the three-dimensional dental device has been completed. Thereafter, any remaining support material is removed by water or other solvent.

A dynamic seal for use in a dental handpiece is disclosed. The dynamic seal includes a seal carrier including a first portion having a first feature for receiving a first compliant member and a second portion having a second feature for receiving a second compliant member, and a flange disposed between the first feature and the second feature.

A medical treatment instrument temperature information management device includes: a wireless tag that is disposed at an instrument; and a reader-writer as a reading unit that reads data from the wireless tag. The wireless tag includes: a temperature sensor; and an IC chip including a storage part. The wireless tag makes the storage part store therein temperature information on temperature of the instrument based on a value detected by the temperature sensor. This makes it possible to manage the temperature information on temperature of the instrument such as a medical treatment instrument with reliability.
