Solution Overview

Problem

Existing methods for inserting digital replicas of dental implants in oral models risk damaging the replicas due to high pressure exertion, especially when there are inaccuracies in the oral model derived from digital printing processes, leading to potential damage of the replica's critical connection surfaces.

Innovation Solution

A tool with a long, threaded inner shaft and a short outer sleeve is used to facilitate the insertion and positioning of digital replicas in oral models, allowing precise placement without applying direct pressure, using complementary threading to secure the replica in place.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Force

If direct pressure is applied to insert the digital replica into the oral model, then insertion force is sufficient to overcome friction and fit the replica in the housing, but the replica's critical connection surfaces may be damaged

Engineering Contradiction:

Improveinsertion forceVSAvoiddamage to replica surfaces

Core Design Contradiction:

ForceVSObject-affected harmful factors

Solution Approach 1:

The patent introduces a specialized insertion tool as an intermediary device between the operator and the digital replica. This tool features a threaded shaft that engages with the replica's internal thread and a compression element that applies controlled force. The intermediary tool distributes the insertion force through the replica's robust body rather than concentrating it on the delicate connection surfaces, thereby achieving sufficient insertion force while preventing damage to critical surfaces.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Manufacturing precision

If high pressure is exerted to overcome friction during insertion due to imprecisions in the oral model, then the replica can be inserted despite manufacturing tolerances, but the replica's connection surfaces are at risk of damage

Engineering Contradiction:

Improveoral model precisionVSAvoiddamage to replica surfaces

Core Design Contradiction:

Manufacturing precisionVSObject-affected harmful factors

Solution Approach 1:

The patent employs parameter changes by introducing a threaded engagement mechanism and a controlled compression system. The threaded shaft engages with the replica's internal thread, allowing for controlled advancement and positioning. The compression element can be adjusted to apply gradual, controlled pressure rather than sudden high force. This changes the insertion parameters from direct high-force impact to controlled threaded advancement with gradual compression, accommodating manufacturing imprecisions while protecting the replica surfaces.

Inventive Principle:

Principle #35Parameter changes

3Ease of operation

If a simple insertion method is used, then the process is quick and easy, but precise positioning of the replica in the oral model cannot be ensured

Engineering Contradiction:

Improveinsertion simplicityVSAvoidreplica positioning precision

Core Design Contradiction:

Ease of operationVSMeasurement precision

Solution Approach 1:

The patent introduces a specialized insertion tool as an intermediary device that provides both ease of operation and precise positioning. The tool's threaded shaft engages with the replica's internal thread, allowing for controlled advancement. The compression element can be adjusted to apply gradual, controlled pressure. This intermediary tool maintains simplicity of operation while ensuring accurate positioning through its controlled mechanical engagement and gradual compression mechanism.

AI summary

The present invention relates to a tool for insertion and positioning of a digital replica of a dental implant in an oral model that facilitates the method for insertion and positioning of a digital replica of a dental implant in an oral model in the laboratory. The tool has a long, threaded inner shaft at the end for coupling to the replica, allowing same to be held, and a short outer sleeve that moves over a thread on the long shaft to ensure the correct positioning of the replica, as it allows the elimination of the space between the replica and the hole in the oral model intended for the housing of the replica itself.
