Jaw Relation Recording With Facial Scan for Digital Dentures
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing denture fabrication processes require multiple dental visits, causing inconvenience and burden to patients, and do not allow for simultaneous acquisition of jaw relation and esthetic positioning of anterior teeth during the first visit.
Innovation Solution
A jaw relation recording apparatus comprising upper and lower jaw plates with impression material and adjustable anterior handles for incisal position recording, and optional anterior guide members for esthetic positioning, enabling simultaneous recording of vertical dimension, centric relation, and occlusal plane at a single visit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional multi-visit denture fabrication process is used, then each step can be performed with dedicated equipment and materials, but the number of patient visits increases to five or more causing inconvenience and burden
Solution Approach 1:
The patent combines multiple denture fabrication steps (impression taking, jaw relation recording, vertical dimension recording, centric relation recording, and occlusal plane recording) into a single integrated apparatus that can be used simultaneously during the first dental visit, eliminating the need for separate visits for each procedure
Solution Approach 2:
The jaw relation recording apparatus is designed with multi-functional components that can perform multiple recording functions (vertical dimension, centric relation, occlusal plane) using a single device structure, allowing all procedures to be completed in one visit
2Measurement precision
If traditional separate procedure approach is used, then each recording can be performed with specialized equipment, but jaw relation and esthetic positioning cannot be determined simultaneously at the first visit
Solution Approach 1:
The patent integrates multiple recording functions (jaw relation, vertical dimension, centric relation, occlusal plane) into a single apparatus structure, where components like the anterior handle, horizontal bar, and recording screws work together in one device to perform all measurements simultaneously
Solution Approach 2:
The apparatus is designed as a universal device that can perform multiple recording functions through its various components, eliminating the need for separate specialized equipment for each procedure while maintaining measurement precision

AI summary
Disclosed is a jaw relation recording apparatus for manufacturing a digital denture, wherein the apparatus can determine an esthetic position of an anterior tooth part by using a facial scanner, as soon as completing acquisition of a jaw relation required for denture manufacture at the time of a patient' s first visit to a hospital, and can provide an accurately manufactured denture on the same day or at the time of second visit to the hospital. A jaw relation recording apparatus for manufacturing a digital denture according to an aspect of the present invention may include: an upper jaw plate having an impression material provided on an upper surface thereof so as to be able to acquire an impression of upper jaw gums; a lower jaw plate having an impression material provided on a lower surface thereof so as to be able to acquire an impression of lower jaw gums; and an anterior guide member which can be detachably coupled to a front end of the upper jaw plate, enables a lip index relation to be acquired after being coupled to the front end, and enables an esthetic position of anterior teeth to be reproduced through a facial scanner in a state of being coupled to the front end.
