Description

Attorney Docket No.: 048794-0914SCREW AND DRIVER FOR DENTAL IMPLANT APPLICATIONSCROSS REFERENCE TO RELATED APPLICATIONS

[0001] The present application claims the benefit of U.S. Patent Application No. 63 / 718,928, entitled “SCREW AND DRIVER FOR DENTAL IMPLANT APPLICATIONS” filed on 11 November 2024, which is incorporated herein by reference in its entirety.FIELD OF THE INVENTION

[0002] The present invention is in the field of dentistry, and, more particularly, is in the field of prosthetic dentistry.BACKGROUND

[0003] One of the clinical limitations for the construction of a prosthesis to restore masticatory function is having adequate engagement between the driver and the screw to secure the prosthesis into the implant or abutment when angulated screw access channels are required. Several screws and drivers exist in the marketplace to allow for angulated engagement of driver into the screw. Some off-axis drivers have a multi-curving shape with polygonal cross-section to engage a corresponding screw with a polygonal inner feature, such as US 11,382,725 B2. The polygonal engagement typically has a hexagonal shape that offers a small intersection between the driver and the screw engaging features causing the potential premature rounding off the conners of the driver and or damaging of the screw. Other drivers have a substantially spherical configuration with hexalobular shape engaging the screw having a corresponding hexalobular inner feature, such as US 10,470,852 B2 and 11,045,288 B2.

[0004] Although the hexalobular engagement having six rounded engaging features provides a slightly higher drive strength than the hexagonal drive system, the drawback of the hexalobular drive system is that it offers tangent points of contact to drive the screw and when the driver is tilted away from the axis of the screw some of the contact points may be lost and or premature deformation of the mating features may occur at required fixation torque. The current off-axis drivers in the marketplace having reduced surface contact between the fastening features when driver is at needed angulated position from the main axis of the screw can cause the components to strip prematurely creating delays and extra cost of the procedure.Attorney Docket No.: 048794-0914In some cases, users may place the screw access channel within the prosthesis at a non-optimal clinical angle to compensate for the limited angle to fasten the screw at the needed torque to prevent screw loosening. Furthermore, the drivers in the marketplace lack the ability to hold the screw tight during handling to prevent these small components from being swallowed or aspirated by the patient. All these drivers and screws have limitations; and a need exists for a driver having adequate surface engagement with the screw at clinically acceptable angulated access channels.SUMMARY

[0005] Disclosed herein are approaches for addressing various of the problems and shortcomings of the state of the art, as identified above. More particularly, disclosed herein is a dental drive system for dental implant applications.

[0007] According to a second aspect of the present disclosure, there is provided a dental drive system comprising a driver comprising a coronal end configured to be engaged by a mechanical or electrical mechanisms, an apical end comprising a substantially rounded outer shape comprising plurality of complementary engaging features, wherein each of the plurality of complementary engaging features comprises a pair of curved flat bearing surfaces, and a body connecting the coronal end and the apical end, and a screw comprising an apical end configured to couple into an abutment or an implant, and a coronal end comprising a plurality of engaging features configured to removably engage with the plurality of complementary engaging features disposed on the apical end of the driver, where each of the plurality of engaging features comprises a pair of independent angled flat bearing surfaces and a middle surfaceAttorney Docket No.: 048794-0914 configured to interact with each of the plurality of complementary engaging features of the driver and where the driver is configured to removably engage with the screw at a substantial angle from a vertical axis of the screw to affix the screw into the abutment or the implant.BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The detailed description set forth below is intended as a description of various configurations of the subject technology and is not intended to represent the only configurations in which the subject technology may be practiced.

The detailed description may include specific details for the purpose of providing a thorough understanding of the subject technology. However, the subject technology is not limited to the specific details set forth herein and may be practiced without these specific details. In some instances, structures and components are shown in block diagram form in order to avoid obscuring the concepts of the subject technology.
