Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dental implant surgical guide design software lacks the ability to effectively recommend a suitable virtual abutment, which is crucial for achieving optimal mechanical fixation and aesthetic outcomes in dental implant surgery.
Innovation Solution
A method and device that recommends a virtual abutment by determining patient-specific or ready-made abutment specifications based on virtual crown and implant body placement, utilizing a prestored abutment library, and adjusting these specifications to ensure compatibility and functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If surgical guide design software is used to place implant body and fix abutment, then mechanical fixing force is improved, but the software lacks ability to recommend suitable virtual abutment which worsens design efficiency
Solution Approach 1:
The system automatically determines patient-specific abutment specifications (outer length of gingival portion, outer shape, diameter, crown insertion height) by analyzing the virtual crown and virtual implant body, then searches the abutment library to recommend matching abutments. This self-service approach eliminates manual abutment selection while maintaining mechanical fixing requirements.
Solution Approach 2:
The system performs preliminary determination of abutment specifications based on the designed virtual crown and implant body before final abutment selection. By pre-calculating required parameters such as gingival portion dimensions and crown insertion height, the system prepares abutment recommendations in advance, improving design workflow efficiency.
2Reliability
If patient-specific abutment is designed with customized specifications, then aesthetic and functional outcomes are improved, but design complexity and time consumption increase
Solution Approach 1:
The system determines patient-specific abutment specifications by calculating key parameters including outer length of gingival portion, outer shape, diameter, and crown insertion height (A/H). These parameter-based specifications enable customized abutment design while maintaining systematic control over design complexity through standardized measurement and comparison.
3Reliability
If abutment specifications are adjusted based on temporary prosthesis strength and final prosthesis material, then mechanical reliability is improved, but calculation and determination process becomes more complex
Solution Approach 1:
The system adjusts abutment crown insertion height (A/H) locally based on specific requirements of temporary prosthesis strength and final prosthesis material. This localized adjustment approach maintains mechanical reliability for different prosthesis types while avoiding complete redesign of entire abutment specifications, thus controlling calculation complexity.

AI summary
A method for recommending a virtual abutment for designing a surgical guide according to one embodiment of the present invention may comprise the steps in which: a design device arranges a virtual crown in dental image data; a virtual implant body is designed according to the arrangement of the virtual crown; when the virtual abutment is set as a patient-customized abutment, at least one of the outer length of a gum part of the patient-customized abutment, the outer shape of the gum part, the diameter of the patient-customized abutment, or the crown insertion height (abutment height, A/H) value of the patient-customized abutment is determined on the basis of the virtual crown and virtual implant body; and an abutment that matches the patient-customized abutment is searched for in a pre-stored abutment library on the basis of the determination.
