Embodiment Construction

[0115] Figure 1 shows a covering device according to the invention. exist Figure 1a A covering device (100) can be seen in Fig. 4 , comprising a lip expansion element (110) shaped as an expander ring, a vestibular expansion element (120) and a membrane (130). The lip opening element (110) is at least nearly planar by plastic forming, although said lip opening element is made of a flexible material and is thus flexible, while the vestibular opening element (120) has a three-dimensional Basic shape with two sections (121, 122) which are oriented in the direction of the lip opening element (110) and thereby narrow the covering device in this area or respectively form a concave inner Reduction portion (124, 125). The curved section ( 121 , 221 , 321 ) can occupy between 10% and 60% of the circumference of the vestibular expansion element ( 120 , 220 , 320 ), but also between 20% and 50%. A preferred value may be around 40%. The circumference can be, for example, 30 cm, and th...

Abstract

The invention relates to cover device for covering the lips and labial commissures, and for holding the lips, cheeks and labial commissures away from the rows of teeth in a patient's mouth, having: an elastic lip clamping element to be placed externally on the mouth opening; at least one elastic vestibular clamping element for insertion into the patient's vestibulum oris; and a film connecting the clamping elements, wherein the clamping elements are arranged along two opposite end regions of the film such that the inserted cover device is open towards the mouth cavity and wherein the vestibular clamping element has at least one portion which runs in the sagittal direction anterior to the vestibular fold when the cover device is inserted.

Description

technical field [0001] The present invention relates to an improved lip-cheek dilator in the form of a covering device for covering the lips and corners of the mouth and for keeping the lips, cheeks and corners of the mouth away from the dentition in the patient's mouth. Background technique [0002] Covering devices used to hold the lips, cheeks, and mouth corners away from the dentition in the patient's mouth are called cheek retractors, retractor hooks, or spreader forceps. Furthermore, WO 03 / 051185 A1 and DE 10 2014 109 023 A1 describe devices in which the lips, cheeks and corners of the mouth are not only kept free of the dentition in the patient's mouth, but also cover the lips and corners of the mouth at the same time. Such devices are known for example under the trade name It is marketed by the company Ivoclar Vivadent AG and has two flexible rings as an expansion frame, which are connected to each other by a cover film. One of the two splay frames is placed entir...
