Dental Implant Insert Adapter for Abutment Orientation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Off-the-shelf dental implant anchors with multi-position coupling interfaces pose challenges in ensuring correct orientation and positioning of customized abutments, as practitioners have a 1 in 6 chance of choosing the correct orientation, leading to potential mismatches and misalignment of individualized restorations.
Innovation Solution
A dental implant anchor insert adapter that converts a multi-position coupling platform into a single position one-way coupling platform, featuring a tubular body with an external surface matching the multi-position interface and an internal surface defining a single position one-way coupling, ensuring precise alignment and orientation of customized abutments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a multi-position coupling interface is used in off-the-shelf implant anchors, then practitioners have flexibility to position abutments in various orientations, but the probability of selecting the correct orientation decreases to 1 in 6
Solution Approach 1:
The patent introduces an intermediary component (the adaptator) that couples between the multi-position coupling interface of the implant anchor and the single-position coupling interface of the customized abutment. This adaptator has multiple positioning elements that can be selectively engaged to establish the correct orientation, thereby mediating between the conflicting requirements of versatility and reliability.
Solution Approach 2:
The coupling system is segmented into three distinct components: the implant anchor with multi-position interface, the adaptator with multiple positioning elements, and the customized abutment with single-position interface. This segmentation allows each component to have optimized functionality - the anchor provides versatility while the adaptator provides precise orientation control.
2Manufacturing precision
If customized abutments are designed and manufactured using CAD/CAM technology, then individualized fit and orientation are achieved, but compatibility with standard multi-position anchor interfaces cannot be ensured
Solution Approach 1:
The adaptator is designed with universal compatibility - its external interface can couple with standard multi-position anchor interfaces while its internal interface couples with customized abutments. This multi-functionality allows the same adaptator design to work with various anchor types and various customized abutments, bridging the compatibility gap.
3Ease of operation
If multiple abutment positions are allowed at the coupling interface, then practitioners have degrees of freedom for positioning, but there is no guarantee that the correct position will be selected
Solution Approach 1:
The adaptator includes multiple positioning elements that are pre-configured in specific orientations and positions. Before final abutment placement, the practitioner selects and engages the appropriate positioning element that corresponds to the desired abutment orientation. This preliminary selection and engagement action ensures that the correct position is established before the abutment is permanently secured.
