This patent application is assigned to
The following quote was obtained by the news editors from the background information supplied by the inventors: "Dental implants are commonly used as anchoring members for dental restorations. The dental implant is typically threaded into a bore which is drilled into the patient's mandible or maxilla. The implant provides an anchoring member for a dental abutment, which in turn provides an interface between the implant and a dental restoration. It may be desirable to provide a multi-unit dental implant system which provides a clinician much versatility of component selection while reducing the total number of components required, therefore simplifying the entire system."
In addition to the background information obtained for this patent application, NewsRx journalists also obtained the inventors' summary information for this patent application: "The disclosure is directed to several alternative designs, materials and methods of manufacturing medical device structures and assemblies.
"Accordingly, one illustrative embodiment is a multi-unit dental implant system. The system includes a dental implant including a threaded shaft having external threads and a central bore including an internal threaded portion. The system also includes a straight abutment and an angled abutment. The straight abutment includes an external threaded portion complementary to the internal threaded portion of the dental implant. The straight abutment includes a cone-section configured to receive a coping thereon. The angled abutment includes a body portion and a retaining screw insertable into a bore of the body portion. The body portion includes an anti-rotation feature configured to be inserted into the bore of the dental implant which prevents relative rotation between the angled abutment and the dental implant while the retaining screw secures the body portion to the dental implant with an external threaded portion complementary to the internal threaded portion of the dental implant. The body portion of the angled abutment includes a cone-section configured to receive a coping thereon. The system also includes a plurality of copings configured to universally fit on the cone-section of the straight abutment and the cone-section of the angled abutment.
"The above summary of some example embodiments is not intended to describe each disclosed embodiment or every implementation of the invention.
BRIEF DESCRIPTION OF THE DRAWINGS
"The invention may be more completely understood in consideration of the following detailed description of various embodiments in connection with the accompanying drawings, in which:
"FIG. 1 is a perspective exploded view of a straight abutment and a dental implant;
"FIG. 2 is a perspective view of a straight abutment coupled to a dental implant;
"FIG. 2A is a cross-sectional view of the straight abutment coupled to the dental implant of FIG. 2;
"FIG. 3 is a perspective exploded view of an angled abutment and a dental implant;
"FIG. 4 is a perspective view of an angled abutment coupled to a dental implant;
"FIG. 4A is a cross-sectional view of the angled abutment coupled to the dental implant of FIG. 4;
"FIG. 5 is a first perspective view of an angled abutment for use with a dental implant;
"FIG. 6 is a second perspective view of the angled abutment for use with a dental implant;
"FIG. 7 is a front view of the angled abutment for use with a dental implant;
"FIG. 8 is a back view of the angled abutment for use with a dental implant;
"FIG. 9 is a first side view of the angled abutment for use with a dental implant;
"FIG. 10 is a second side view of the angled abutment for use with a dental implant, which is a mirror image of the first side view;
"FIG. 11 is a top view of the angled abutment for use with a dental implant;
"FIG. 12 is a bottom view of the angled abutment for use with a dental implant;
"FIG. 13 illustrates an exemplary placement of the angled abutment and dental implant in the anatomy;
"FIG. 14 illustrates an exemplary placement of the straight abutment and dental implant in the anatomy; and
"FIG. 15 illustrates additional components which may be universally used with either the straight abutments or angled abutments described herein.
"While the invention is amenable to various modifications and alternative forms, specifics thereof have been shown by way of example in the drawings and will be described in detail. It should be understood, however, that the intention is not to limit aspects of the invention to the particular embodiments described. On the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the invention."
