Title:
RETAINER FOR AN ORTHODONTIC TREATMENT AND METHOD FOR PRODUCING A RETAINER OF THIS TYPE
Document Type and Number:
WIPO Patent Application WO/2022/242800
Kind Code:
A3
Abstract:
A retainer (5) generally consists of a plurality of individual or optionally contiguous double wings (6). Each double wing (6) consists of a middle piece (7) and two wings (8), which laterally adjoin the middle piece and are designed for surface-to-surface adhesive bonding to the peripheral surface of a tooth (1, 2). This middle piece (7) is set, approximately at half the height of the tooth crown, between two teeth (1, 2), where the middle piece extends, as far as possible and sharply, into the gap between the teeth (1, 2). The two wings (8) follow the gingival margin (4) and end approximately in the sagittal plane (9) of a tooth. In order to produce a retainer (5), an electronic image of the intraoral side of a tooth-row contour is captured and said electronic image is used to produce a customized retainer (5), for example by means of a 3D printer or a 3D milling machine, i.e. for example to print or to mill the customized retainer. If the adhesive bond of a double wing (6) loosens over time, the adhesive bond of said double wing can be restored without the entire retainer (5) having to be detached from the teeth (1, 2). If a double wing is damaged or lost, the function of the retainer is substantially maintained even at the affected tooth.
