Fluid Motion Generator for Dental Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dental and endodontic procedures are painful and often incomplete, as they fail to remove all unhealthy material from teeth, leading to post-procedure complications such as infection, due to the use of mechanical instruments that can force organic material into periapical tissues and damage surrounding tissues.
Innovation Solution
An apparatus and method utilizing a chamber with a fluid motion generator to create rotational fluid motion within the tooth, allowing for the safe and efficient removal of unhealthy materials from both inside and outside the tooth, using a combination of pressure waves and fluid motion to clean and obturate the treatment region without damaging healthy dentin or enamel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mechanical instruments such as drills and files are used to clean teeth and root canals, then the treatment can be performed with conventional equipment, but unhealthy material may not be completely removed and organic material may be forced into periapical tissues causing infection and trauma
Solution Approach 1:
The patent replaces mechanical drilling and filing instruments with a fluid-based system that uses pressurized fluid jets to remove unhealthy material from teeth and root canals. The fluid motion generator creates high-velocity fluid streams that dissolve and flush out organic material without mechanical contact, eliminating the risk of forcing material into periapical tissues while achieving complete cleaning.
Solution Approach 2:
The invention employs hydraulic principles by using pressurized fluid delivery systems to transport cleaning agents through the tooth structure and flush out debris. The fluid-based approach uses hydrodynamic forces rather than mechanical forces to achieve material removal, preventing contamination of surrounding tissues.
2Productivity
If endodontic files are inserted into root canals to remove organic material, then the canal spaces can be opened, but the procedure may force organic material through the apical opening into periapical tissues
Solution Approach 1:
The patent replaces mechanical filing action with fluid dynamics-based material removal. High-velocity fluid jets dissolve organic material and use hydrodynamic pressure to flush debris out through controlled pathways, preventing the extrusion of organic material into periapical tissues that occurs with mechanical filing.
Solution Approach 2:
The invention introduces fluid as an intermediary medium between the cleaning action and the tooth structure. The fluid acts as a carrier that dissolves organic material and transports it out of the root canal system in a controlled manner, eliminating direct mechanical contact that causes material extrusion.
3Ease of operation
If conventional mechanical drilling is used to break up carious regions, then access can be obtained to the tooth interior, but the procedure is painful and may not remove all diseased material
Solution Approach 1:
The patent replaces painful mechanical drilling with non-contact fluid jet delivery. The fluid-based system accesses carious regions and dissolves diseased material through chemical and hydrodynamic action, eliminating drilling pain while achieving more complete removal of pathology through thorough flushing.
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
The solution effectively removes all unhealthy materials from the tooth, reducing the risk of infection and patient discomfort by using fluid motion and pressure waves to clean and fill the tooth without the need for mechanical instruments, thereby improving patient outcomes.
Implementation Method 1
a fluid motion generator being arranged to generate rotational fluid motion in the chamber
Implementation Method 2
a suction port configured to remove fluid from the treatment region and the chamber. The apparatus can be configured to draw outgoing fluid from the treatment region to the suction port in a path that flows inside the swirling influent fluid path with a suction force applied to the suction port

AI summary
Various systems, method, and compositions for treating a tooth are disclosed herein. For example, an apparatus for treating a tooth is disclosed. The apparatus can include a chamber having an access port which places the chamber in fluid communication with a treatment region of the tooth when the chamber is coupled to tooth. A fluid motion generator can be coupled to the chamber. The fluid motion generator can be configured to direct fluid across the access port to generate fluid motion in the chamber. In various embodiments, fluid motion (e.g., vortices, swirl, etc.) can be induced at or near treatment regions of the tooth, such as a root canal or carious region.
