Dental Vibration Apparatus for Resin Bubble Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dental treatment instruments face challenges in attaching resins to teeth without forming air bubbles, which can cause pain and resin separation due to variations in resin viscosity and bubble formation during the multi-layer application process.
Innovation Solution
A vibration apparatus for dental care that controls the viscosity of resins by transmitting vibrations within a specific frequency range of 3 to 70 Hz, using a vibration motor, tip part, and controller to ensure uniform application and removal of air bubbles, thereby facilitating smooth resin attachment and shaping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If resin is repeatedly applied in multiple layers to suppress spaces or air bubbles, then the completeness of tooth restoration is improved, but air bubbles are generated inside the resin during the process
Solution Approach 1:
The patent applies mechanical vibration at a frequency of 20 Hz or more to the resin during and after application. This vibration causes air bubbles trapped within the resin to move and rise to the surface, where they can be removed. The vibration frequency is specifically set to resonate with the natural frequency of air bubbles in resin, maximizing the effect of bubble removal while maintaining complete tooth restoration.
2Stability of the object's composition
If resin viscosity is high for stable attachment, then the stability of resin attachment is improved, but air bubbles are difficult to remove and shaping becomes difficult
Solution Approach 1:
The patent employs periodic action by applying vibration at specific frequencies (20 Hz or more) during the resin application process and continuing it for a predetermined period after application. This periodic mechanical stimulus temporarily reduces resin viscosity during shaping, making bubble removal and contouring easier, while allowing the resin to regain its stable, high-viscosity state after the vibration stops, ensuring stable long-term attachment.
3Reliability
If vibration frequency is increased to remove air bubbles, then the effectiveness of bubble removal is improved, but the resin structure may be damaged
Solution Approach 1:
The patent carefully controls the vibration frequency parameter, setting it to 20 Hz or more but within a specific range that resonates with air bubbles without exceeding the threshold that would damage the resin structure. This parameter optimization allows effective bubble removal while preserving the integrity and strength of the resin restoration.

AI summary
Disclosed is a vibration apparatus for dental care including a body in which a vibrator is embedded; a tip part connected to the body to extend to an outside of the body and configured to transmit vibration energy of the vibrator to a resin applied to a tooth; and a controller configured to control a magnitude of vibration energy generated from the vibrator and transmitted to the tip part, wherein the controller controls a vibration frequency of the tip part within a range of 3 to 70 Hz. According to such configuration, the viscosity of resin attached to a tooth is lowered so that the resin can be easily formed into a desired shape and the tooth can be treated without generation of voids in the resin.
