Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for inserting digital replicas of dental implants in oral models risk damaging the replicas due to high pressure exertion, especially when the oral model has inaccuracies from printing processes, leading to friction issues.
Innovation Solution
A tool with a long inner shaft and a short outer sleeve is used to facilitate the insertion and positioning of digital replicas, utilizing complementary threading to avoid direct pressure on the replica, ensuring precise placement without damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If pressure is applied to insert the digital replica into the oral model, then the replica can be positioned in the housing, but the replica surface may be damaged
Solution Approach 1:
The patent introduces a specialized insertion tool as an intermediary device between the operator and the digital replica. This tool includes a pressing element that applies force through a distributed surface area rather than a concentrated point, and a threaded engagement mechanism that gradually advances the replica into the housing. The tool acts as a mediator that transfers the insertion force while protecting the replica's critical surface areas from direct contact and damage.
Solution Approach 2:
The insertion tool is divided into distinct functional segments: a pressing element with a broad contact surface, a threaded engagement section that interfaces with the replica, and a handling portion. This segmentation allows each component to perform its specific function - the pressing element distributes force, the threaded section provides controlled advancement, and the handling portion allows operator control - thereby enabling precise positioning without surface damage.
2Ease of operation
If high pressure is exerted to overcome friction during insertion, then the replica can be inserted despite printing inaccuracies, but the replica may be damaged
Solution Approach 1:
The insertion tool employs a dynamic insertion process where the threaded engagement mechanism allows for gradual, controlled advancement of the replica into the housing. Rather than applying static high pressure, the tool enables dynamic adjustment - the operator can rotate the threaded section to incrementally advance the replica, overcoming friction and printing inaccuracies through a progressive motion that maintains control and prevents sudden damage.
Solution Approach 2:
The threaded engagement mechanism serves as a mechanical intermediary that converts rotational motion into linear advancement. This intermediary mechanism allows the operator to overcome friction and positioning inaccuracies through a controlled screwing motion, distributing the force application over multiple small increments rather than requiring a single high-pressure application, thereby preventing replica damage.
3Manufacturing precision
If the oral model has printing inaccuracies, then the housing may not fit the replica perfectly, but forcing insertion can damage the replica
Solution Approach 1:
The insertion tool provides a dynamic adjustment mechanism through its threaded engagement system. When printing inaccuracies prevent a perfect fit, the operator can use the threaded section to gradually advance the replica into the housing, making real-time adjustments to accommodate variations in the housing dimensions. This dynamic process allows the system to adapt to manufacturing tolerances without requiring forceful insertion that would damage the replica.
Solution Approach 2:
The pressing element of the insertion tool is designed with a broad contact surface that distributes insertion forces over a larger area of the replica. This design provides a form of prior cushioning by preventing concentration of stress at any single point on the replica surface, thereby protecting against damage even when high forces are required to overcome fitting difficulties caused by printing inaccuracies.

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.
