Compositions comprising one or more chelating agents and optionally zinc ion salts are used to inhibit the growth or biofilm formation in bacteria associated with personal care products such as ophthalmic, pedicure, manicure or podiatric solutions. The compositions of the present application can also comprise gelling agents, antimicrobials, antibiotic or a pH adjuster. The compositions may be in the form of a solution, a gel, a cream, a jelly, a powder, a paste, a lotion, soap and a cleaner.

Disclosed is a method for determining the geometrical relationship between a patient's dental structure and a reference feature on the head of the patient, the method including obtaining a first digital representation of a facebow including a fiducial marker, an adjustable pin member attached to the facebow and an attachment section of the facebow for placing the facebow in relation to the reference feature, the attachment section having a geometrical relationship with the fiducial marker; obtaining a second digital representation comprising a part of the patient's dental structure, a part of the pin member, and part of the facebow including the fiducial marker; obtaining information about the placement of the attachment section relative to the reference feature; and determining the geometrical relationship between the patient's dental structure and the reference feature based on the first and second digital representations and the placement of the attachment section.

A facebow-free transfer method includes: registering virtual upper and lower casts respectively to an upper teeth part of a virtual maxilla model and a lower teeth part of a virtual mandible model so as to form a virtual teeth and jaw model; mounting the virtual teeth and jaw model on a virtual articulator; generating a virtual occlusion transfer module that is mounted on the virtual articulator and that has a part extending to and fitting in an in-between space of virtual upper and lower casts of the virtual teeth and jaw model; and creating an actual occlusion transfer device that is to be mounted on an articulator based on the virtual occlusion transfer module.

The invention concerns methods and a device for the determination of the centric position of a human set of teeth with improved precision. This is needed for the adjustment of an articulator in the production of dentures. For this purpose a plurality of successive bite movements or displacement movements of the lower jaw are recorded in form of electronic signal data and evaluated for the determination of the centric position.
