Solution Overview

Problem

The invasive and costly surgical removal of third molars, commonly known as wisdom teeth, results in significant pain, complications, and unnecessary healthcare costs due to the inability to predict which teeth will cause future pathology, leading to elective surgeries with high complication rates.

Innovation Solution

A minimally invasive tooth bud ablation (TBA) procedure using microwave or radio frequency ablation guided by custom surgical stents and precise ablation probe tips to eliminate tooth buds before they fully form, reducing the need for traditional extractions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional surgical removal of third molars is performed, then teeth are removed, but significant pain, complications, and high costs result

Engineering Contradiction:
Improvecomplication rateVSAvoidpain and complications
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent performs ablation of the third molar tooth bud before it fully develops and erupts. By taking preventive action during the bud stage (when the tooth is still forming), the procedure eliminates the need for future extraction surgery, thereby avoiding the pain and complications associated with traditional surgical removal while maintaining high reliability

Inventive Principle:
Principle #10Preliminary action

2Reliability

If prophylactic extraction of all third molars is performed, then future pathology is prevented, but unnecessary surgeries and high healthcare costs occur

Engineering Contradiction:
Improveprediction accuracy of future pathologyVSAvoidhealthcare resource utilization
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent applies different approaches to different third molars based on individual assessment. Instead of universally extracting all third molars, the system uses imaging and clinical evaluation to identify which specific tooth buds pose a risk of future pathology, and only those are ablated. This localized, targeted approach prevents unnecessary procedures while maintaining high reliability in preventing actual pathology

Inventive Principle:
Principle #3Local quality

3Ease of operation

If traditional extraction surgery is performed, then teeth are removed, but significant post-operative discomfort and disability result

Engineering Contradiction:
Improveprocedure simplicityVSAvoidpost-operative discomfort
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent replaces the mechanical surgical extraction process with a minimally invasive ablation procedure. Instead of using surgical instruments to cut and remove developed teeth, the system uses energy-based ablation (such as laser or electro-surgical ablation) to selectively remove tooth bud tissue through a small access opening. This substitution dramatically reduces post-operative discomfort while maintaining procedural simplicity

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

AI summary

A method for volume scanning of both hard tissues (126) and gingival tissues (122) of a patient is proposed. The method includes comprising the steps of using an impression (84) of a material visible in a volume scan, generating a volume scan in which hard tissue (126) is visible and said impression (84) is visible, and gingival tissue (122) being represented as the space between the visible hard tissue (126) and the visible impression (84). The volume scan includes a surgical site (162) to receive an ablation probe tip (108). The results of the step of generating a volume scan are provided for the purpose of manufacturing a custom surgical stent (110) having at least one surgical guide (112) for guiding placement of an ablation probe tip (108). The results comprise information representing said gingival tissue (126) and said hard tissue (126).
