Solution Overview
Problem
Current tooth removal tools face challenges in efficiently pre-loosening teeth by fracturing the bond between the tooth and alveolar bone, particularly in accessing curved or pointed molars and maintaining effective contact surfaces.
Innovation Solution
A kit and method using a power tool to apply alternating, rotating, or vibratory forces to the tooth root surface through reconfigurable attachments, including elongate stems and two-piece constructions, to generate linear, rotary, or translational forces that fracture the bond between the tooth and bone, facilitating tooth extraction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional dental pliers are used to grasp and remove teeth, then the tooth can be removed, but the bond line between the tooth and alveolar bone cannot be effectively fractured, making removal difficult and traumatic
Solution Approach 1:
The attachment applies preliminary forces (oscillatory, vibratory, rotating, or linear) to the tooth root surface before extraction to fracture the bond line between the tooth and alveolar bone. This preliminary action weakens the strong bond, making subsequent removal easier and less traumatic.
Solution Approach 2:
The attachment can apply oscillatory or vibratory forces to the tooth root surface, causing mechanical vibration that helps fracture the bond line between the tooth and bone, facilitating easier removal while reducing trauma.
2Productivity
If force is applied to curved or pointed molars to fracture the bond line, then pre-loosening is achieved, but maintaining effective contact surfaces becomes difficult
Solution Approach 1:
The attachment features a reconfigurable body with movable engagement surfaces that can adapt to curved or pointed molar geometries. The dynamic adjustment of contact surfaces allows effective force application to various tooth shapes while maintaining proper engagement throughout the pre-loosening process.
Solution Approach 2:
The attachment body is divided into multiple reconfigurable components including movable engagement surfaces and adjustable elements, allowing the device to be configured for different tooth geometries and access requirements, thereby maintaining effective contact on curved or pointed molars.
3Productivity
If alternating bi-directional forces are applied to fracture the bond line, then tooth pre-loosening is achieved, but the application requires precise control over force direction and cycles
Solution Approach 1:
The attachment applies periodic alternating bi-directional forces to the tooth root surface for a predetermined number of cycles. This periodic action systematically fractures the bond line through repeated loading in opposite directions, achieving reliable pre-loosening with controlled force application.

AI summary
The present invention discloses a tool, kit and method for applying loading, torsional/twisting, oscillatory or vibration induced forces to a bond line established between a tooth root surface and an associated bone defined socket within which the tooth is held. Forces are applied typically for a given number of cycles or iterations in order to adequately pre-loosen the tooth from the bone. In a most basic variant, a body is adapted to being engaged by an output portion of a force applying tool. The body includes a pair of tooth engaging portions adapted to being inserted into contact with opposite surfaces of the tooth root surface and opposing surfaces associated with the bone receiving socket. The tool introduces loading forces to the engaging portions, causing the tooth to displace within the socket sufficiently to fracture the bond with the bone, thereby facilitating tooth removal.
