Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing dental prosthesis installation processes are time-consuming, costly, and require a waiting period for bone integration, often leading to patient discomfort and potential misalignment or damage due to unguided drilling.

Innovation Solution

A multi-piece dental prosthesis system that allows concurrent installation with the implant, featuring a guided drill path and removable components for easy replacement, utilizing a ti-base with a central opening and threads for secure attachment, enabling a regular dentist to perform the procedure.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a conventional implant design with separate components is used, then the implant can be manufactured using standard procedures, but the implant lacks adaptability to different patient anatomies and requires multiple separate surgical steps

Engineering Contradiction:

Improveadaptability to patient anatomyVSAvoidimplant structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines the implant body, abutment, and crown into a single monolithic structure that can be customized for each patient's anatomy. This merging eliminates the need for multiple separate components and surgical steps, while providing full adaptability to individual patient requirements through custom fabrication methods

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The single-piece implant design serves multiple functions simultaneously: it acts as the implant body for osseointegration, the abutment for supporting the crown, and the crown itself for restoration. This multi-functionality provides universal applicability across different patient anatomies without requiring separate components

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If multiple separate implant components are used, then manufacturing and inventory management is simplified, but the risk of complications from multiple surgical steps and component assembly increases

Engineering Contradiction:

Improvereliability of implant integrationVSAvoidmanufacturing process

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

By merging all functional components into a single monolithic structure, the patent eliminates interfaces between components that could fail or become infected. The single-piece design reduces surgical complexity and improves reliability by removing potential failure points associated with multiple components and assembly steps

Inventive Principle:

Principle #5Merging (Combining)

3Productivity

If traditional multi-step implant procedures are used, then standardized treatment protocols can be followed, but the treatment time and patient discomfort are increased

Engineering Contradiction:

Improvetreatment efficiencyVSAvoidtreatment duration

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The implant is designed and fabricated before the surgical procedure, with the final crown structure already in place. This preliminary action allows the entire restoration to be completed in a single surgical step, eliminating the need for multiple follow-up procedures and significantly reducing total treatment time

Inventive Principle:

Principle #10Preliminary action

AI summary

A multi-piece dental prosthesis system is provided. The system includes an implant which can be implanted into a bone of the patient, an abutment removably connected to the implant by a prosthetic screw, and a ti-base removably connected to the abutment. The system may be used to hold a crown, denture, or partial denture in place.
