Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dental separator devices and matrix systems lack improved control over contact areas and embrasures, ease of placement, visualization, and patient comfort during dental restorations, particularly in the posterior region of the mouth.
Innovation Solution
A dental separator device with a spring-tensioned yoke and angled tines, combined with a contoured matrix band that hugs the teeth, providing better stabilization and control over the interdental space, allowing for improved visibility and reduced discomfort during restorative procedures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional dental separators and matrix systems are used, then basic tooth separation is achieved, but control over contact areas and embrasures is insufficient
Solution Approach 1:
The device is divided into distinct functional segments: a separator component with opposing arms for tooth separation, and a matrix band holding component with clamping arms. This segmentation allows each component to be optimized for its specific function while working together as an integrated system, improving control over contact areas and embrasures.
Solution Approach 2:
The matrix band is nested within the separator device structure, with the separator's clamping arms designed to hold and stabilize the matrix band in place. This nested configuration allows the matrix band to be securely positioned against the tooth while the separator maintains control over the contact areas and embrasures, achieving precise control without complicating the placement procedure.
2Illumination intensity
If conventional separators are used, then tooth separation is achieved, but visualization during the procedure is limited
Solution Approach 1:
The separator device and matrix band holding function are merged into a single integrated instrument. The separator's clamping arms are designed to simultaneously hold the matrix band and maintain separation, eliminating the need for multiple separate instruments and improving visualization by reducing clutter in the operative field.
3Object-affected harmful factors
If conventional matrix stabilization methods are used, then basic stabilization is achieved, but patient comfort is reduced
Solution Approach 1:
The clamping arms are designed with differentiated local qualities: the inner surfaces contacting the matrix band are smooth and contoured to distribute pressure evenly, while the outer surfaces have engagement features for secure holding. This localized optimization of surface properties provides reliable matrix stabilization while minimizing discomfort to the patient's soft tissues.

AI summary
A dental separator device for applying pressure against adjacent teeth to separate the teeth from one another so that a dental restoration can be made. The separator device increases the interproximal space between the adjacent teeth giving the dental clinician improved visibility and working space. The invention also encompasses a flexible matrix band used for making the restoration. The matrix band is wrapped around the tooth to define a desired mold or shape for the restoration.
