Dental Restoration Fastening Channel Angulation for Implant Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge of configuring a fastening channel through a dental restoration for retaining a dental implant is complicated by the variability in the relative position and orientation of the implant due to individual anatomical features, leading to potential issues with visibility, functionality, structural stability, and accessibility of the fastening mechanism.
Innovation Solution
A computer-implemented method adjusts the position and orientation of the fastening channel by angulating it relative to the implant's central longitudinal axis, ensuring it meets predefined positioning criteria such as material thickness, visibility, and accessibility, using 3D digital models and user inputs to optimize the channel's placement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the fastening channel is positioned according to the implant's central longitudinal axis, then the fastening mechanism is structurally stable, but the channel may be positioned in a visible area compromising aesthetic appeal
Solution Approach 1:
The patent introduces an angulation parameter to the fastening channel configuration, transforming it from a simple axial alignment problem to a three-dimensional spatial optimization problem. By allowing the channel to deviate from the implant's central longitudinal axis within controlled angular limits, the system achieves both structural stability and aesthetic appeal by positioning the channel in less visible areas.
2Ease of operation
If the fastening channel is angulated to improve aesthetic appeal and accessibility, then visibility and tool operation space are improved, but the channel position may violate material thickness requirements
Solution Approach 1:
The patent implements a dynamic evaluation process where the angulation of the fastening channel is adjusted and re-evaluated against multiple criteria including material thickness, aesthetic appeal, and accessibility. This dynamic optimization allows the system to find the optimal angulation that satisfies all constraints simultaneously, rather than using a fixed angular value.
3Adaptability or versatility
If the fastening channel position is manually configured, then flexibility in positioning is achieved, but the configuration process is time-consuming and complex
Solution Approach 1:
The patent implements an automated evaluation and adjustment system that performs the fastening channel configuration independently. The system automatically evaluates multiple candidate positions against predefined criteria (aesthetic appeal, accessibility, material thickness, neural structure avoidance) and selects the optimal position without requiring manual intervention, thereby reducing configuration time while maintaining flexibility.
4Strength
If the fastening channel is positioned to ensure material thickness, then structural integrity is maintained, but the channel may be positioned in areas with poor accessibility for tool operation
Solution Approach 1:
The patent changes the angular parameter of the fastening channel to simultaneously satisfy multiple constraints. By adjusting the angulation within specific ranges, the system can position the channel in areas that maintain sufficient material thickness for structural integrity while also providing adequate accessibility for tool operation during the fastening process.

AI summary
The invention relates to a method for a computer-implemented method for configuring a fastening channel through a dental restoration for fastening a retaining means retaining the dental restoration. The method comprises receiving a 3D digital restoration model of the dental restoration with an artificial tooth and a definition of an implant. A relative positioning of the dental restoration relative to the implant is determined. A position of the fastening channel extending from the implant through the artificial tooth is determined. In case the position of the fastening channel violating a set of one or more pre-defined positioning criteria. The position of the fastening channel is automatically adjusted by angulating the fastening channel such that the positioning criteria are satisfied.
