Abstract

The present invention relates to dental implants and abutments and comprise a set of surgical navigation guided abutments having an indicator, used for alignment of dental implants and dental abutments with neighboring teeth or another abutments.

Description

SURGICALLY GUIDED AND NAVIGATED ABUTMENTS FIELD OF THE INVENTION

The present invention relates to dental implants and abutments.

BACKGROUND OF THE INVENTION

A dental prosthesis for replacing one or more missing teeth may be accomplished by placement of one or more dental implants in the jawbone and corresponding number of abutments to which the dental prosthesis is secured thereto. The abutment is normally screwed or bonded into the implant. The implant is generally made from a titanium alloy or other rigid materials which are non-reactive with human tissue or fluid.

It is well known that the angle of a dental abutment must be aligned with the intended angle of the path of insertion of the restoration and must be maintained from abutment to abutment, in cases where multiple implants are employed, to facilitate a smooth and nontraumatic insertion and function of a removable or a fixed appliance. The determination of the most desirable path of insertion of the appliance may be governed by factors such as the position of adjacent natural teeth, arc of closure, ridge contour and the patient's dexterity.

Various attempts have been made in the past to properly align the dental abutment so that a prosthetic tooth, which is to be formed on the dental abutment, properly aligns with the neighboring teeth.

One example of the prior art system for adjustably aligning the prosthetic tooth is the "Paraguide System for Implant Parallelism" by ALPHA-BIO Tec Ltd. (shown on http://alpha-bio.net/_Uploads/dbsAttachedFiles/Catalog.pdf ). The "Paraguide System" comprise one straight abutment, two angled abutments (15°, 25°) and a rotation tool. The use of this system is as follows: the implant is placed at the alveolar crest level, the specific "Paraguide" abutment (0°, 15°, 25°) is inserted into the implant, the implant is screwed into the bone with the help of the "Paraguide" abutment and the rotation tool (which is inserted into perpendicular hole of "Paraguide" abutment), until the "Paraguide" abutment is parallel to other abutments.

While this prior art "Paraguide System" make provision for aligning a prosthetic tooth with the neighboring teeth, there are several disadvantages. These would include a necessity to use a special rotational tool, more complex abutments (i.e. abutments having a perpendicular hole) and et cetera.

In short, the prior art system do not present a simple, practical method for alignment of implants.

SUMMARY OF THE INVENTION

The purpose of present invention is to provide a simple, practical method for alignment of dental implants and dental abutments. The present invention comprise a set of surgical navigation guided abutments, which may be manufactured from sturdy stainless steel and which are analogous to standard titanium or zirconium abutments.

This set comprise three abutments: one straight (0°) and two angled (15°, 25°) surgical navigation guided abutments.

The straight surgical navigation guided abutment comprise a cylindrical body having a male rotational engagement surface (said engagement surface may be a polygonal surface, such as hexagonal protrusion) at the apical end and female rotational engagement surface (said engagement surface may be a polygonal surface, such as hexagonal depression) at the coronal end. Said cylindrical body has at least one notch or groove on its outer surface and said notch or groove corresponds to one facet of said engagement surface.

The angled surgical navigation guided abutment comprise a cylindrical body having a male rotational engagement surface (said engagement surface may be a polygonal surface, such as hexagonal protrusion) at the apical end, angled protrusion ( of 15° or 25°) and female rotational engagement surface (said engagement surface may be a polygonal surface, such as hexagonal depression) at the coronal end. Said cylindrical body has at least one notch or groove on its outer surface and said at least one notch or groove corresponds to one facet of said engagement surface.

The present invention also comprise a method of aligning dental implant and dental abutment, so that a prosthetic tooth, which is to be formed on the dental abutment, properly aligns with the neighboring teeth.

In order to align dental implant and/or dental abutment to desired position, the surgical navigation guided abutment is inserted into dental implant and said implant is screwed into the bone with the help of surgical navigation guided abutment and standard driver tool (which is engaged with female rotational engagement surface of the surgical navigation guided abutment) until alignment achieved between guided abutment and the neighboring teeth or another abutment.
