Solution Overview

Problem

The manufacturing of ceramic dental implants is inefficient and costly due to the brittle nature of ceramic materials, which makes traditional machining techniques like grinding time-consuming and expensive, especially for creating inner contours and structures.

Innovation Solution

A method using a rotating disc advanced perpendicularly to its rotation axis to remove ceramic material efficiently, creating inner structures such as insertion geometries, rotation locks, and positioning structures in ceramic implants and attachment elements, allowing for faster and more cost-effective production.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If traditional grinding methods are used to create inner contours of ceramic implants, then manufacturing precision can be achieved, but production time and cost significantly increase

Engineering Contradiction:

Improveinner contour precisionVSAvoidproduction speed

Core Design Contradiction:

Manufacturing precisionVSProductivity

Solution Approach 1:

The patent inverts the conventional grinding approach by using a rotating disc that removes material radially from the inner surface rather than using end-face or peripheral grinding. This inversion of the grinding direction enables efficient material removal while maintaining precision, directly resolving the contradiction between production speed and manufacturing precision for inner contours

Inventive Principle:

Principle #13The other way round (Inversion)

2Ease of manufacture

If ceramic material is removed using conventional machining techniques, then inner structures can be created, but the brittle nature of ceramic makes the process time-consuming and expensive

Engineering Contradiction:

Improveinner structure creationVSAvoidmachining time

Core Design Contradiction:

Ease of manufactureVSLoss of time

Solution Approach 1:

The patent transitions from conventional one-dimensional end-face grinding to a two-dimensional radial cutting approach using a rotating disc. This dimensional change allows simultaneous engagement of multiple cutting points on the ceramic surface, dramatically reducing machining time while maintaining ease of manufacture for inner structures

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

AI summary

A method for manufacturing an inner structure as an insertion geometry and/or as a rotation lock of a ceramic implant or of a ceramic attachment element. Thereby, a rotating disc for removing ceramic material is advanced in an advance direction of the rotating disc perpendicular to the rotation axis of the disc, into a proximally accessible surface of the ceramic implant or into an end surface of a ceramic attachment element.
