Solution Overview

Problem

Existing dental implant procedures require multiple steps involving scanning abutments, which cause patient discomfort and disrupt the healing process, and require expensive intraoral scanning equipment, while existing systems lack accurate post-operative virtual data for creating permanent prostheses.

Innovation Solution

A robotic system with a grounding arm and working arm, equipped with sensors, is used to install dental implants and generate positional data for creating a post-operative virtual three-dimensional model, eliminating the need for scanning abutments and intraoral scanning.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If scanning abutments are used to obtain implant position data, then accurate virtual three-dimensional model data is obtained, but patient discomfort increases and the healing process is disrupted

Engineering Contradiction:
Improveaccuracy of implant position dataVSAvoidpatient discomfort and disruption to healing
Core Design Contradiction:
Measurement precisionVSObject-affected harmful factors

Solution Approach 1:

The robotic system performs preliminary registration and tracking setup before the implant procedure. The system establishes a virtual model and tracks the surgical plan in advance, allowing the implant to be placed directly without requiring subsequent scanning abutment procedures. This preliminary action eliminates the need for patients to undergo additional invasive procedures after the initial surgery.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent replaces the mechanical scanning abutment system with a robotic tracking system that uses sensors and virtual modeling. Instead of physically scanning the implant site with abutments after surgery, the system uses pre-operative imaging, robotic arm tracking, and virtual three-dimensional modeling to capture and process implant position data non-invasively.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Measurement precision

If intraoral scanning equipment is used to create virtual models, then accurate post-operative data is obtained, but system cost increases

Engineering Contradiction:
Improveaccuracy of post-operative virtual modelVSAvoidcost of scanning equipment
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The robotic system performs multiple functions: it guides the surgical procedure, tracks implant placement in real-time, and generates the virtual three-dimensional model. This multi-functional approach eliminates the need for separate expensive intraoral scanning equipment, as the same robotic system with its sensors and tracking capabilities accomplishes all tasks.

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

Solution Approach 2:

The robotic system uses its own positional data and pre-operative imaging to automatically generate the post-operative virtual model. The system self-determines implant location and orientation through its tracking sensors and registration process, eliminating the need for external scanning services or equipment.

Inventive Principle:
Principle #25Self-service

3Reliability

If multiple procedures including scanning abutment replacement are performed, then complete dental restoration is achieved, but treatment time increases

Engineering Contradiction:
Improvecompleteness of dental restorationVSAvoidtreatment duration
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

All necessary measurements, planning, and virtual modeling are performed before the surgical procedure. The robotic system is pre-registered with the patient's anatomy, and the surgical plan is predetermined. This allows the actual surgery to proceed efficiently without interruptions for additional scanning or measurement procedures that would extend treatment time.

Inventive Principle:
Principle #10Preliminary action

AI summary

A robotic system includes a base, a grounding arm, a working arm, and one or more sensors. The grounding arm extends from the base and is configured to be coupled to a fixed structure within the mouth of the patient for establishing an origin for the robotic system. The working arm extends from the base and is configured to be coupled with one or more tools for use during an installation of a dental implant in the mouth. The one or more sensors are for monitoring positions of the grounding arm and/or the working arm and to generate positional data that is used to create a post-operative virtual three-dimensional model of at least a portion of the mouth of the patient.
