Solution Overview

Problem

Current dental implant connection platforms lack a robust anti-rotational structure and effective indexing function, and are not adaptable for switching between single-tooth and multiple-teeth restorations, which limits their clinical versatility and osseointegration with the alveolar bone.

Innovation Solution

A dental implant design featuring a conical portion with a conical half angle between 10-20 degrees, an interlock recess with flat sides forming a hexagonal or octagonal shape, and a threaded portion, providing a tapered fit and enhanced seal, while allowing for multiple types of dental restorations and improved osseointegration.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If an internal connection platform is used with a conical upper portion and internally-threaded shaft, then the connection provides structural support, but it does not tolerate misalignment and cannot switch between different types of dental restorations

Engineering Contradiction:
Improveadaptability to different restoration typesVSAvoidconnection stability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The connection platform is divided into distinct functional zones: a conical upper portion for alignment and sealing, a substantially cylindrical middle portion for anti-rotational engagement, and a lower threaded portion for secure fastening. This segmentation allows each zone to perform its specific function optimally while working together to provide both versatility and reliability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The connection platform is designed with multiple functional capabilities within a single structure: the conical portion provides alignment and sealing, the cylindrical portion with flat sides provides anti-rotational engagement, and the threaded portion provides secure fastening. This multi-functionality enables the same implant to accommodate various restoration types (single crowns, bridges, dentures) while maintaining connection stability.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Stability of the object's composition

If a hexagonal protrusion external connection platform is used, then the anti-rotational structure is provided, but the sealing between components is compromised

Engineering Contradiction:
Improveanti-rotational stabilityVSAvoidsealing deficiency
Core Design Contradiction:
Stability of the object's compositionVSObject-generated harmful factors

Solution Approach 1:

The invention merges the anti-rotational function (typically provided by hexagonal protrusions) with the sealing function (typically provided by conical interfaces) into a single integrated connection platform. The conical upper portion provides the seal, while the substantially cylindrical middle portion with flat sides provides anti-rotational engagement, eliminating the need to choose between one function or the other.

Inventive Principle:
Principle #5Merging (Combining)

3Object-generated harmful factors

If the connection platform is designed for precise alignment, then the sealing is enhanced, but the tolerance for misalignment during installation is reduced

Engineering Contradiction:
Improvesealing qualityVSAvoidinstallation tolerance
Core Design Contradiction:
Object-generated harmful factorsVSEase of operation

Solution Approach 1:

The conical upper portion of the connection platform performs the preliminary action of self-alignment during insertion. The conical geometry naturally guides the abutment into proper alignment as it is inserted, ensuring the sealed interface is achieved without requiring precise pre-alignment by the operator. This preliminary self-alignment action maintains both sealing quality and installation ease.

Inventive Principle:
Principle #10Preliminary action

AI summary

A dental implant, components, and kit are provided. The implant can comprise a body, attachment means for attaching the implant to bone, and a recess. The recess can be disposed within the body and open towards a proximal end thereof. The recess can comprise a proximally-disposed receiving chamber and a distally-disposed threaded chamber. The receiving chamber can comprise an interlock chamber, which can be disposed at a distal end of the receiving chamber and have a polygonal cross-section. The implant can be multi functional such that components for various dental prostheses and procedures can be provided having portions that can, for example, engage the interlock chamber of the implant, mate with the receiving chamber of the implant, and/or mate with the proximal end the implant for supporting the prosthesis and/or facilitating the procedure.
