Abstract

The invention relates to an adaptor system for a dental prosthesis. The adaptor system comprises an abutment and an adaptor, wherein said adaptor is adapted to connect to a prior art or new implants and is also connected to the abutment by a rotational connection. The adaptor and the abutment are secured to the implant by a screw that retains the angular position of the abutment.

Description

ADAPTOR SYSTEM FOR DENTAL PROSTHESIS
BACKGROUND Technical Field
This disclosure relates to dental structures in general and more specifically to an adaptor mechanism for attachment of a dental prosthesis.
Description of the Related Art
Dental implant systems are widely used for replacing damaged or lost natural teeth. In such systems, a dental implant is placed in the jawbone of a patient in order to replace the natural tooth root and to preserve the current rehabilitation of the teeth. An abutment structure comprising one or several parts may then be attached to the implant in order to build up a core for the part of the prosthetic tooth protruding from the bone tissue, through the soft gingival tissue, and into the mouth of the patient. On said abutment, the prosthesis or crown may finally be seated.
The final prosthesis should be sized and configured so as to naturally fit with the remaining teeth of the patient, for both functionality and aesthetics. To this end a dental technician may try out a proper prosthesis for the individual patient, using a model of the jaw of the patient. The dental technician may also digitally work out a proper prosthesis based on a digital model of the jaw of the patient.
Many abutment/implant interfaces are designed with hexagonal protrusions and matching hexagonal recesses. For instance, the abutment may be provided with a hexagonal protrusion that is adapted to mate with a corresponding hexagonal recess in the implant when the two components are to be joined.
Dentists sometimes experience difficulties with axial alignment of the abutment, as the hexagonal protrusion mating with the hexagonal recess allows only six possible axial positions of the abutment. The common abutment with hexagonal protrusion has no adjustment ability and after the abutment placed there is no adjustment ability that allows to get to an accurate placement relating the final desire work .
l An object of the invention is to make it possible for dentists to connect a dental component, such as an abutment, to an implant at any axial position. As a consequence, that allows to fit a prosthesis (such as a dental bridge) without making any adjustments to it, even if the spatial positions of the abutments were changed from the time when the measurements were taken for making the prosthesis. As a result, the invention provides a more accurate and less time consuming method for dental restorations.
SUMMARY OF THE INVENTION
According to a first aspect of the invention, an adaptor system for a dental prosthesis is provided. The adaptor system comprises an abutment and an adaptor connected to each other and to an implant by mating connections and a screw. The abutment is connected to the adaptor by a mating connection that allows axial rotation of said abutment when the screw is untightened. This allows a dentist to rotate the abutment to a desired angle for attaching a prosthesis or any other dental structure to it.
According to a second aspect of the invention, a method for aligning a dental abutment is provided. In this method when there is a need to align the abutment to a desired angle, the screw is untightened and the abutment is rotated to a desired axial position. After that the screw is tightened again.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. l is an exploded view of the components of at least one embodiment of the invention.
FIG.2 illustrates an adaptor according to at least one embodiment of the invention.
FIG.3 illustrates an abutment according to at least one embodiment of the invention.
FIG.4 illustrates another view of an abutment according to at least one embodiment of the invention. DETAILED DESCRIPTION
Beginning with FIG. 2, an adaptor 30 according to an embodiment of the invention is illustrated. The adaptor 30 comprises a hexagonal protrusion 31, said hexagonal protrusion 31 is adapted to mate with a hexagonal recession of an implant 40. The adaptor 30 additionally comprises an annular ledge 32 that is adapted to mate with an annular recession of the implant 40 and to cover the top surface of the implant 40. The adaptor 30 additionally comprises a connector 33 with an annular protrusion 34 on its edge. The connector 33 has a cylindrical form and comprises at least two bendable sections 35 separated by a slit 36.
FIG. 3 and FIG. 4 depict an abutment 20 with a through-hole 22 that mates with the connector 33 of the adaptor 30. Additionally, the abutment 20 also comprises an annular groove 21 located on the inner surface of the hole 22. The groove 21 is adapted to mate with the annular protrusion 34 when the connector 33 is inserted into the hole 22. The groove 21 and the protrusion 34 create a so called snap or "click" connection. The mating between the protrusion 34 and the groove 21 prevents vertical displacement of the abutment 20 while preserving a rotational freedom of said abutment 20.
The adaptor 30 and the abutment 20 are provided with a central through-hole, through which a screw 10 is inserted and connected to an internal thread of the implant 40. The screw 10 comprises a tapered upper part 11 that is adapted to press on the inner surface of the bendable sections 35 of the connector 33, thus creating friction between said bendable sections 35 and the inner surface of the hole 22 of the abutment 20. Said friction prevents a rotation of said screw 10 and abutment 20, and maintains the abutment 20 in the preferred radial position.
The present invention also comprises a method for aligning a dental abutment. Initially, an abutment 20 is connected to an adaptor 30 and both of them are secured to an implant 40 by a screw 10. When there is a need to align the abutment 20 to a desired angle, the screw 10 is untightened and the abutment 20 is rotated to a desired axial position. After that the screw 10 is tightened again. Although the drawings illustrate dental components provided with mating elements in the form of hexagonal projections and hexagonal recesses, it should be understood that in other embodiments, the mating elements of the dental components may have any other forms.
Furthermore, although the drawings illustrate the adaptor as a male component having a protrusion to be inserted into a socket or recession of the implant, other embodiments are also conceivable.
