Problems solved by technology

Placing a denture over ball attachments which are connected to not parallel implants causes difficulties in the insertion and removal of the denture and causes damage to the ball and transfers damaging forces to the dental implants and the bone.
Placing a regular ball attachment over a misplaced implant causes difficulties in the fabrication of the denture.
A conventional ball attachment, as illustrated in FIG. 1a, has no anti-rotational element and therefore, it can not be used as an angulated ball attachment because the correct angle can not be determined by the doctor.
The use of two parts increases the risk of the screw loosening and assembly in the patient's mouth is more difficult for the doctor.
Further, if the screw becomes loose, the non-rotational connection between base 6 and plate 9 will not be maintained, which may lead to breakage of one of the parts or damage to the surrounding area of the mouth.

Embodiment Construction

[0043]The present invention is second preferred embodiment of an angulated ball attachment device constructed and operational according to the teachings of the present invention.

[0044]The principles and operation of second preferred embodiment of an angulated ball attachment device constructed and operational according to the teachings of the present invention according to the present invention may be better understood with reference to the drawings and the accompanying description.

[0045]By way of introduction, the present invention relates an angulated ball attachment device which is deployed such that the ball component is off-set from the central axis of the implant. The ball component and the abutment base element form a single rigid unit that is stable even in case the attachment screw of the device becomes loosened.

[0046]In some preferred embodiments the abutment base element is deployed at least partially inside the dental implant.

[0047]The angulated ball attachment device of...

Abstract

The present invention relates an angulated ball attachment device which is deployed such that the ball component is off-set from the central axis of the implant. The ball component and the abutment base element form a single rigid unit that is stable even in case the attachment screw of the device becomes loosened.

Description

FIELD AND BACKGROUND OF THE INVENTION[0001]The present invention relates to dental attachment devices and, in particular, it concerns second preferred embodiment of an angulated ball attachment device constructed and operational according to the teachings of the present invention.[0002]In many cases of dental implants the implants are inserted in a non-parallel manner, due to bone architecture. Placing a denture over ball attachments which are connected to not parallel implants causes difficulties in the insertion and removal of the denture and causes damage to the ball and transfers damaging forces to the dental implants and the bone. In some cases the implant are located buccally or lingually to the desired location of the ball. Placing a regular ball attachment over a misplaced implant causes difficulties in the fabrication of the denture.[0003]In cases of regular implants for fixed restorations, when the implants are inserted at an angle to the prosthetic element other than the ...
