Solution Overview
Problem
Existing dental drills lack an efficient mechanism to direct irrigation fluid to the surgical site during dental procedures, leading to inadequate heat management and potential tissue damage.
Innovation Solution
A dental implement with a fluted guide body that directs irrigation fluid to the surgical site, reducing the need for external irrigation systems and allowing for single-handed operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a dental drill is used to form bores in jaw bone, then material and tissue removal is achieved, but heat is generated causing tissue damage
Solution Approach 1:
Irrigation fluid is introduced as an intermediary substance between the cutting tool and the jaw bone. This fluid serves as a heat transfer medium that carries thermal energy away from the surgical site, preventing direct heat transfer to surrounding tissues while allowing continuous cutting operation.
Solution Approach 2:
The patent employs hydraulic principles by utilizing liquid irrigation fluid to cool the cutting area. The fluid is delivered through a controlled system that maintains adequate flow rates to effectively remove heat generated during bone cutting, replacing purely mechanical cooling methods.
2Temperature
If external irrigation systems are used to supply irrigation fluid, then heat management is improved, but device complexity increases
Solution Approach 1:
The irrigation system is merged with the dental drill assembly, integrating the cooling function into the existing tool structure. The irrigation fluid delivery channels are incorporated within the drill body, eliminating the need for separate external irrigation equipment and reducing overall system complexity.
Solution Approach 2:
The dental drill assembly is designed to perform multiple functions: cutting bone material and simultaneously delivering irrigation fluid for cooling. This multi-functionality consolidates what would traditionally require separate devices into a single integrated tool, reducing the number of components needed during surgery.
3Temperature
If internal irrigation systems are developed, then heat generated during bore formation is reduced, but the volume of irrigation fluid communicated to the surgical site is limited
Solution Approach 1:
The irrigation delivery system is segmented into multiple channels and outlets distributed along the drill shaft. This segmentation allows the total irrigation fluid volume to be divided into multiple flow streams that reach the surgical site simultaneously, increasing the effective cooling coverage without requiring a single large fluid delivery system.
Solution Approach 2:
The irrigation fluid delivery is extended along the longitudinal dimension of the drill shaft, with multiple outlets positioned at different axial locations. This three-dimensional distribution of fluid delivery points maximizes the coverage area and volume of irrigation fluid reaching the surgical site compared to a single-point system.
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 fluted guide body effectively increases the volume of irrigation fluid communicated to the surgical site, enhancing heat management and reducing the risk of tissue damage during dental procedures.
Implementation Method 1
at least one longitudinal flute configured to facilitate communication of an irrigation fluid to a surgical site within a patient
Implementation Method 2
To reduce heat generated during formation of the bore(s), both internal and external irrigation systems have been developed that supply irrigation fluid to the surgical site

AI summary
A dental implement includes a cutting head and a guide body. The cutting head defines proximal and distal ends and includes at least one cutting surface, with all cutting surfaces of the implement being exclusively located on the cutting head. The guide body is positioned proximally of the cutting surfaces and includes at least one longitudinal flute that extends between proximal and distal ends of the guide body. The flute is configured to facilitate communication of irrigation fluid to a surgical site within a patient. A stop is formed integrally with the guide body and extends radially outward from its proximal end. The stop defines a maximum transverse cross-section of the implement extending orthogonally to the implement's longitudinal axis and is configured to contact a surgical guide to limit advancement of the implement during use.
