Soft Tissue-Supported Provisional Denture for Accurate Bone Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional implant-supported denture fitting and bone reduction procedures are challenging due to the need for iterative grinding and test fitting, which can be painful and inaccurate, especially in cases where bone reduction is required and the patient's anatomy is not well-suited for traditional denture systems.
Innovation Solution
A removable system featuring a soft tissue-supported provisional denture with connectors that can be trimmed or broken off to stabilize and position the denture, and a cut or break-away section in the denture baseplate for bone reduction, allowing for accurate and rapid adjustment to individual anatomy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional denture baseplate is used as trimming guide, then bone reduction can be performed, but access to the area needing reduction is prohibited and accuracy is compromised
Solution Approach 1:
The denture baseplate is segmented into removable portions that can be detached to provide access to bone reduction areas. This allows the baseplate to serve as both a trimming guide and an access-enabling structure, resolving the contradiction between maintaining guidance accuracy and providing surgical access.
Solution Approach 2:
The baseplate transitions from a static conventional design to a dynamic structure with removable sections. This dynamic configuration allows the baseplate to adapt during surgery, providing both guidance and access as needed, thereby improving both accuracy and ease of operation.
2Manufacturing precision
If iterative grinding and test fitting is performed, then denture fitting can be adjusted, but patient pain is exacerbated and fitting time is prolonged
Solution Approach 1:
The denture baseplate is pre-configured with removable portions and attachment features that enable direct bone reduction and attachment without iterative adjustments. This preliminary preparation eliminates repeated grinding and test fitting cycles, reducing both time and patient discomfort while maintaining fitting accuracy.
Solution Approach 2:
The removable portions of the baseplate act as intermediaries that facilitate direct bone reduction and provide reference surfaces for accurate fitting. This intermediary structure eliminates the need for repeated trial fittings, thereby reducing fitting time and patient pain while preserving precision.
3Productivity
If conventional denture fitting is performed immediately after surgery, then healing process can begin, but overtrimming risk increases due to pain and urgency
Solution Approach 1:
The baseplate is pre-designed with removable portions and attachment features that enable accurate bone reduction and fitting in a single procedure. This preliminary configuration allows immediate post-surgical fitting without compromising accuracy, as the structure is already optimized for the specific patient anatomy and implant positions.
Solution Approach 2:
The baseplate's removable portions automatically provide access and guidance during fitting, enabling the procedure to be self-guiding without requiring repeated adjustments. This self-service mechanism maintains high trimming accuracy while enabling rapid fitting immediately after surgery.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Minimizes patient discomfort by facilitating precise and efficient fitting and bone reduction, reducing the risk of overtrimming and improving the accuracy of the denture fitting process during the healing period after surgery.
Implementation Method 1
adhesive is applied to the underside of the provisional denture, and implant connectors are seated on the implants. The implant connectors adhere to the adhesive and transfer the implant positions to the provisional denture

AI summary
A removable system and method for helping position and stabilize implant supported dentures during the healing process after surgery is provided, wherein a removable system comprises a soft tissue supported provisional denture structure configured to help position and stabilize the provisional denture during the transfer of the implant positions to the provisional denture. In the surgical process of providing implant-supported dentures, immediately after the implants are surgically implanted, adhesive is applied to the underside of the provisional denture, and implant connectors are seated on the implants. The provisional denture is seated in the patient's mouth wherein the soft tissue supported provisional denture structure helps stabilize and position the denture. The implant connectors adhere to the adhesive and transfer the implant positions to the provisional denture.
