Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dental prosthetic solutions lack flexibility in adapting to patient-specific needs and often cause stress due to complex scanning processes, which complicates the transfer of the dental component's structure into a digital model.
Innovation Solution
A dental component comprising a gingiva former and a scan body, designed for connection to a dental implant, with features for secure fixation and scannability, allowing precise scanning and alignment, and facilitating easy transfer into a digital model.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a traditional multi-step impression taking process is used, then the dental implant environment can be conveyed to a technician, but the process is time-consuming and causes patient stress
Solution Approach 1:
The patent uses digital optical scanning to create a digital copy of the dental implant environment, replacing traditional physical plaster or resin impressions. The scan body with specific geometric features (polygonal projection unit, planar unit, oblique connecting unit) enables accurate digital reproduction of the implant position and orientation, significantly reducing treatment time while maintaining measurement precision
Solution Approach 2:
The patent replaces the mechanical impression-taking process with an optical scanning system. Instead of using physical materials like plaster or resin to capture the dental implant environment, an intraoral scanner with optical recording techniques (film or CCD chip) is used to digitally capture the scan body and convey the implant environment information, eliminating the time-consuming mechanical impression process
2Measurement precision
If a scan body with complex geometric features is used for accurate scanning, then the digital model precision is improved, but the device complexity increases
Solution Approach 1:
The scan body incorporates specific geometric features that create distinct optical signatures for accurate scanning. The polygonal projection unit with multiple planar units at different orientations, connected by oblique connecting units, creates unique light reflection patterns that enable precise digital recognition and orientation detection by the intraoral scanner, improving scanning accuracy through optical differentiation
Solution Approach 2:
The scan body uses specific geometric shapes including polygonal projections and planar surfaces with defined orientations. These curved and angular features create distinct optical signatures that facilitate accurate digital model reconstruction while maintaining a relatively simple overall structure that can be easily manufactured and attached to the dental implant
3Ease of operation
If the scan body and healing abutment are separated, then the procedural convenience is improved, but the transfer of structural information into digital model becomes more difficult
Solution Approach 1:
The scan body is designed as a separate component that can be attached to different types of healing abutments and dental implants. The standardized geometric features (polygonal projection unit with planar units and oblique connecting units) serve universal scanning purposes regardless of the specific healing abutment type, allowing procedural flexibility while maintaining consistent digital information transfer across different clinical scenarios
