Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Dental implants often face challenges in optimizing the use of available bone material and space due to the limitations of standardized drill diameters, lengths, and conical angles, which can lead to suboptimal positioning and integration with the jawbone.
Innovation Solution
A method involving customized dental implant and tooling manufacturing using scan data to create virtual models, allowing for on-demand production of tailored drills and osteotomes through computer-aided manufacturing and 3D printing, enabling precise fit and optimal use of bone space for osseointegration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If standardized drills with fixed diameters, lengths, and conical angles are used, then manufacturing and inventory management are simplified, but the available bone space cannot be optimally utilized and implant positioning becomes suboptimal
Solution Approach 1:
The patent applies parameter changes by transitioning from fixed standardized drill parameters to variable customizable parameters. The system allows drill diameter, length, and conical angle to be adjusted based on individual patient anatomy and implant requirements, enabling optimal bone space utilization while maintaining manufacturing feasibility through computer-aided design and modern manufacturing processes
Solution Approach 2:
The patent implements local quality by customizing drill parameters for specific local conditions in each patient's jawbone. Rather than using universal standardized drills, the system tailors drill characteristics to match the local bone density, available space, and implant positioning requirements at each specific surgical site
2Manufacturing precision
If customized drills with variable diameters, lengths, and conical angles are manufactured, then optimal use of bone space and implant positioning is achieved, but manufacturing complexity and production time increase
Solution Approach 1:
The patent applies preliminary action by performing virtual planning and customization of drill parameters before actual manufacturing. The system uses computer-aided design to pre-determine optimal drill specifications based on patient anatomy, allowing for precise customization while streamlining the subsequent manufacturing process through digital modeling and preparation
Solution Approach 2:
The patent replaces traditional mechanical manufacturing systems with computer-aided manufacturing processes. By using digital modeling, virtual simulations, and computer-controlled manufacturing equipment, the system achieves complex customized drill geometries more efficiently, reducing the practical complexity despite the increased customization requirements
3Ease of operation
If multiple standardized drill sizes are maintained in inventory, then drill availability is improved, but storage space and inventory management complexity increase
Solution Approach 1:
The patent applies universality by creating a flexible manufacturing system that can produce various drill specifications from a single customizable platform. Rather than maintaining separate inventories for multiple standardized drill sizes, the system uses computer-aided manufacturing to produce the specific drill configuration needed for each patient, eliminating the need for extensive drill inventories while maintaining full availability of required specifications
