摘要:
The invention could be categorized as a telescopic crown, the purpose of which is the attachment of a dental prosthesis to a dental implant, and it can be used in the procedures of dental prosthesis or dental implantation. The fixation of this new telescopic crown to a dental implant provides the possibility to prevent any damage to and maintain the integrity of a dental prosthesis when placing it on or removing it from a dental implant. The purpose of the invention is to develop a telescopic crown for the attachment and fixation of the dental prosthesis to the dental implant, that could increase the reliability and efficiency of the removal/ attachment procedure of the dental prosthesis, in particular, that could increase the efficiency of the service of the dental prosthesis, and thereby solving the problems, especially related to one-piece dental implants and the service of their dental prosthetics. The innovation in telescopic crown, having a bowl-shaped hood (1), is that the cover (3) has the uplifting thread (4) with windings (5) that allow removing the telescopic crown from the implant abutment (14) with the help of fixating screw (15), and the cavity with the internal thread (6) for fixation of the crown to the implant abutment (14) with the fixating screw (15) is designed, and a cone-shaped cavity (2) is designed in the inner wall (8) of the hood (1), and supporting steps (10) are designed in the lower part of the hood for finishing and supporting the prosthesis, and they can have different height depending on the thickness of the soft tissues, and indicative grooves (13) are designed while their number depends on the height of the steps, and fixating grooves (9) from the middle part of the crown towards the upper slope of the step are designed. The uplifting thread (4) has 1-20 windings (5), its diameter is not more than 5.00 mm, the thickness of the hood (1) wall (8) is at least 0.1 mm, the angle of conical connection is 1-20 degrees, and it is parallel t
