Denture Socket Grooves for Adhesive Flow Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current denture manufacturing methods face challenges in achieving accurate fitting of artificial teeth to sockets due to adhesive leakage and uneven application, leading to labor-intensive adjustments and potential aesthetic and functional issues.
Innovation Solution
The method involves creating grooves on the artificial tooth and denture base surfaces to control adhesive flow and discharge, ensuring precise fitting and bonding by forming discharge holes that allow excess adhesive to be easily removed, thereby minimizing manual adjustments and enhancing the accuracy of occlusal contact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If adhesive is applied to the socket for bonding artificial teeth, then bonding strength is improved, but adhesive leakage occurs causing uneven distribution and requiring manual adjustments
Solution Approach 1:
The socket inner surface is divided into multiple grooves that segment the adhesive application areas. This segmentation allows controlled adhesive distribution in each groove while preventing uncontrolled leakage between grooves, thus maintaining bonding strength without compromising fitting accuracy
Solution Approach 2:
The grooves are strategically positioned at specific locations within the socket where adhesive application is most beneficial. This local quality approach ensures adhesive is concentrated where needed for bonding strength while avoiding areas where leakage would affect fitting accuracy
2Reliability
If adhesive is applied generously to ensure complete coverage, then bonding reliability is improved, but excess adhesive requires labor-intensive removal and adjustment
Solution Approach 1:
The grooves are pre-formed in the socket structure before adhesive application. This preliminary action creates predetermined pathways that guide adhesive flow, ensuring complete coverage for bonding reliability while automatically containing excess adhesive within the grooves, eliminating the need for labor-intensive removal
Solution Approach 2:
The grooves act as intermediary structures between the adhesive and the bonding interface. They mediate the adhesive flow by providing controlled pathways that ensure complete coverage without allowing uncontrolled excess adhesive to interfere with the fitting process
3Ease of manufacture
If the socket structure is simplified for ease of manufacture, then manufacturing complexity is reduced, but adhesive control and discharge capability are compromised
Solution Approach 1:
The grooves are designed as simple segmented features that can be easily manufactured using standard CAD/CAM processes. This segmentation provides effective adhesive control without significantly increasing manufacturing complexity, maintaining ease of manufacture while improving adhesive distribution control

AI summary
A method for manufacturing a denture includes: preparing an artificial tooth and a denture base with a concave socket; applying an adhesive to the concave socket; and embedding the artificial tooth in the concave socket to which the adhesive is applied. A socket groove is defined on an inner surface defining the concave socket. The socket groove extends from a concave bottom surface of the concave socket facing a basal surface of the artificial tooth to a lingual concave side surface of the concave socket. Embedding the artificial tooth in the concave socket includes: forming a discharge hole to discharge the adhesive, the discharge hole being defined at an end of the socket groove on a lingual outer surface of the denture base; and discharging the adhesive from the discharge hole.
