Dental Hand Piece Drill Angle Correction System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dental hand pieces lack the accuracy to achieve the optimal three-dimensional space-angle necessary for precise dental surgical procedures, leading to suboptimal convergence angles in metal-ceramic crown abutments and dental implant placements, which results in reduced retention force and increased complications.
Innovation Solution
An apparatus and method that includes a housing with real-time angle sensing units for the dental hand piece and the patient's head, an operating unit for correcting the drill angle, and a display unit to alert the operator of deviations from a predetermined reference angle, allowing for precise adjustment without the need for bulky tracking systems or additional cameras.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If existing dental hand piece is used relying on operator's motion skill and space perception ability, then the device complexity is low, but the manufacturing precision of the drill angle is insufficient
Solution Approach 1:
The patent replaces the mechanical system of manual angle control with an electronic sensing and feedback system. Gyro sensors and acceleration sensors detect the actual drill angle in real-time, and the operating unit automatically corrects the angle by controlling the dental hand piece's movement, substituting operator skill with electronic measurement and control.
Solution Approach 2:
The patent implements a closed-loop feedback system where sensors continuously measure the drill's three-dimensional space angle, the operating unit compares it with the target angle, and automatically adjusts the drill position to correct any deviation, ensuring precise angle control throughout the surgical procedure.
2Measurement precision
If computer guided navigation system with bulky tracking systems and additional cameras is used, then the measurement precision is improved, but the device complexity and ease of operation deteriorate
Solution Approach 1:
The patent merges the angle measurement and correction functions into a single integrated apparatus attached to the dental hand piece itself. The sensing units, operating unit, and display unit are combined in one compact system, eliminating the need for separate tracking systems and cameras while maintaining measurement precision and improving ease of operation.
3Measurement precision
If computer guided navigation system is used, then the measurement precision is improved, but the productivity decreases due to increased operation time
Solution Approach 1:
The patent enables continuous real-time measurement and correction of the drill angle throughout the entire surgical procedure. The sensing units continuously monitor the angle, and the operating unit continuously makes adjustments, ensuring precision is maintained without interruption or additional setup time, thereby maintaining high surgical productivity.
