摘要： A method is provided for designing and fabricating a removable partial denture (RPD) framework including clasp retainers configured for removable engagement with abutment teeth of a patient. The method includes obtaining an initial digital model of the RPD framework based on patient image data. For each clasp retainer, a set of relevant geometric parameters is identified, each relevant geometric parameter being provided with a nominal value, and a target value of dislodging force is provided. The method further includes performing a force analysis on the initial digital model to determine corrected values for the relevant geometric parameters of each clasp retainer such that when the corrected values are assigned to the relevant geometric parameters, the dislodging force matches its target value. The method also includes obtaining a corrected digital model based on the corrected values, and fabricating the RPD framework based on the corrected digital model.

摘要： The invention relates to a specimen part (1) for creating a stress-free fit, a so-called passive fit, of implant-supported and/or abutment-supported bridges (2) and bars (3) by means of a CAD/CAM tool for the creation of restorations (5), and to a method for creating a restoration from a digital model (15) of a patient's jaw provided with at least two implants and/or abutments, wherein the model (15) is determined by means of an intraoral scan (14). In order to improve the precision of restorations and to shorten the production process, provision is made that the specimen part (1) per implant (4) and/or abutment has a scannable structure (6), preferably at a defined distance (7) and angle (8) to the implant (4) and/or abutment. In the method according to the invention, a specimen part (1) is produced from the model (15) by means of CAD/CAM, the specimen part (1) is checked in terms of its dimensional match to at least two implants (4) and/or abutments and if necessary is corrected, the specimen part (1) is scanned, and a digital model (15) of the optionally altered specimen part (1) is generated, which model is used to generate a restoration (16) manufactured by CAD/CAM.

摘要： A precision attachment system for mounting a dental prosthesis (1) to a retention bar (2) having a round section (2a) and an off-centred support section (2b), and a C-shaped retention clip (3) which is incorporated into the dental prosthesis (1) and encloses the round section (2a). A spacer clip (4) is adapted for both the retention clip (3) and the retention bar (2). The contact of the dental prosthesis (1) with the indirect retainer surface (8) of the support section (2b) prevents the free-end saddles from lifting off the alveolar ridge (10). The resilience of the dental prosthesis (1) in the direction of the atrophying alveolar ridge (10) remains possible. The indirect retainer surface (8) and the slotted flange (12) of the housing (11) guide the retention clip (3) to the round section (2a) when assembled with the retention bar (2).

摘要： A non-removable bridge dental prosthesis includes an artificial tooth to be inserted into a region from which a tooth has been lost, a bridge tightly fixed to the rear surfaces of the teeth on either side of the region from which the tooth was lost, and a coupling member for coupling the artificial tooth to the bridge. The coupling member is integrally installed on the rear surface of the artificial tooth, and has a catching piece and a coupling projection. A coupling hole is formed in the bridge in a shape corresponding to the coupling projection and is located at a position where the coupling projection of the coupling member is formed. The coupling projection is inserted in the coupling hole of the bridge and simultaneously, the catching piece is caught on the top end of the bridge.

摘要： A flexible clasp for removable mounting of a partial dental prosthesis to an abutment tooth is disclosed. The clasp includes a retention arm (42) formed to extend around at least a portion of the side of an abutment tooth (27) to retain the prosthesis in an edentulous space (26). In the improved clasp (41), the retention arm (42) is coupled to the prosthesis at a location in the edentulous space, preferably about one tooth width from abutment tooth (27) so as to cantilever support the retention arm (42) for resilient lateral displacement with respect to the abutment tooth. Preferably, a resiliently displaceable tubular member (51) is mounted to the retention arm (42) which is held to the prosthesis by a clip (43) surrounding the tubular member (51) and arm (42). The method of the present invention includes coupling the prosthesis to the clasp (41) through the retention arm portion (42) of the clasp while maintaining the resilient displaceability of the retention arm (42) to provide both a retention function and a stress relieving function.
