Adjustable Dental Guide Fixation Pin for Variable Implant Depths
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dental surgical guides face issues with invasive fixation methods that cause trauma, require multiple models for different implant depths, and lack stability and ease of handling.
Innovation Solution
A dental guide fixator with a fixed pin and adjustable regulator that attaches to the internal thread of a dental implant, ensuring constant height and stability, allowing a single model to fit various implant depths and sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixation pin is inserted into the anchorage hole and the guide is fixed directly to the patient's gums, then the guide achieves fixation, but the gingival bone is traumatized requiring additional perforations
Solution Approach 1:
The patent introduces an intermediary fixation pin that engages with the implant's internal thread rather than directly piercing the gum tissue. This mediator approach allows the guide to be secured to the implant structure without causing trauma to the gingival bone, eliminating the need for additional perforations while maintaining reliable fixation.
2Reliability
If threaded pins are used to fix the guide to the implant, then the guide achieves stability, but the stability depends on the precise height of the fixation pin which depends on the implant depth
Solution Approach 1:
The patent implements a dynamic adjustment mechanism where the fixation pin includes an adjustable thread section that can be rotated to change its effective length. This allows the pin to adapt to different implant depths and configurations, providing stable guide fixation without requiring multiple specialized pin models for different clinical scenarios.
Solution Approach 2:
The fixation pin incorporates a variable length thread section that can be adjusted by rotating the pin within the implant's internal thread. This parameter change capability allows the same pin design to accommodate different implant depths and types, eliminating the need for multiple fixed-length pin models while maintaining consistent guide stability.
3Reliability
If different fixation pins are manufactured for different clinical cases, then each case receives optimal fixation, but the device complexity increases
Solution Approach 1:
The patent designs a universal fixation pin that can function across multiple clinical scenarios through its adjustable mechanism. The pin with its rotatable thread section can be adapted to various implant depths, diameters, and orientations, providing optimized fixation for different cases without requiring separate specialized pins for each clinical situation.
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
Provides stable, reliable, and easy-to-use fixation for surgical guides, compatible with sterilization, and adaptable to different clinical cases without requiring multiple models.
Implementation Method 1
the apical region of the body of the fixed pin has a diameter substantially smaller than the rest of said fixed pin, in order to allow the apical region to be fixed to the internal region of a dental implant
Implementation Method 2
said regulating element is threaded onto the fixed pin in order to compress the guide between the guide fixation region and the surface of the patient's tooth

AI summary
The invention refers to a dental guide fixator for guided surgical procedures fixed in an internal region of at least one implant comprising: —a fixed pin being inserted using a key or manually with an apical region comprising a fixation thread region comprising an adjustment thread and a regulating element comprising an internal thread configured to be threaded to the adjustment thread and having a guide fixation region; the regulating element is threaded onto the fixed pin being passed through a hole in a surgical guide and fixed to the internal thread of a dental implant through the fixation thread in the apical region, whereby the guide fixation region comes into contact with the guide and said regulating element is threaded onto the fixed pin in order to compress the guide between the guide fixation region and the surface of the patient's mouth.
