Barium Silicate Dental Cement Radiopacity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current dental cements lack sufficient radiopacity and require additional radiopaque compounds, which can introduce toxicity, corrosion, or reactivity issues when used in bone or teeth.
Innovation Solution
A dental cement utilizing barium silicate compounds, specifically mono-barium silicate, dibarium silicate, and tribarium silicate, to achieve radiopacity without the need for additional radiopaque additives, combined with an anhydrous organic carrier for syringe delivery and optional anti-microbial agents like zinc pyrithione.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If additional radiopaque compounds (tantalum, bismuth, zirconium) are added to current dental cements, then radiopacity is improved, but toxicity and reactivity issues worsen
Solution Approach 1:
The patent merges the radiopacity function with the base cement material by incorporating barium silicate compounds (monobarium silicate, dibarium silicate, and tribarium silicate) into the dental cement composition. This eliminates the need for separate radiopaque additives while providing both structural and radiographic properties in a single integrated material system.
Solution Approach 2:
Barium silicate compounds serve multiple functions simultaneously: they provide the necessary radiopacity for imaging, contribute to the mechanical strength of the cement, and offer biocompatibility without the toxic side effects associated with traditional radiopaque additives. This multi-functional approach resolves the contradiction between radiopacity and safety.
2Object-affected harmful factors
If barium silicate compounds are used to achieve radiopacity, then toxicity is reduced, but manufacturing complexity increases
Solution Approach 1:
The patent utilizes different polymorphic forms of barium silicate (monobarium, dibarium, and tribarium silicates) with varying degrees of reactivity and curing characteristics. By selecting and combining specific polymorphic forms, the formulation can be optimized to balance manufacturing ease, setting time, and final properties, thereby managing manufacturing complexity while maintaining safety benefits.

Implementation Method 2
Current dental cements are delivered in the form of an anhydrous paste that cures to a solid mass by reaction with water to form a mineral complex/hydrate
Implementation Method 3
reaction with water to form a mineral complex/hydrate
Implementation Method 4
optional anti-microbial agents like zinc pyrithione

AI summary
A dental cement with improved radiopacity and delivery methods may feature active barium silicate compounds such as mono-barium silicate, dibarium silicate, and tribarium silicate. The barium silicate compounds are manufactured and then mixed into a paste with an anhydrous carrier and stored in a syringe. Storage in the syringe maintains the paste in an anhydrous state until applied to a treatment site, when water and moisture may be naturally or artificially applied to the paste and begin the curing process. The cement may be use in both dental and orthopedic fields.
