Silicone Rubber Dental Composition for Sensitivity Relief
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dental compositions for temporary tooth repair and sensitivity relief are complex to apply, require excessive wait times, and often cause discomfort due to their aqueous-based formulations, which can react prematurely and produce foul tastes or rough textures.
Innovation Solution
A non-aqueous delivery platform using a combination of uncured, uncrosslinked silicone high consistency rubber base material and dry powdered ingredients, including xanthan gum, arginine bicarbonate, and calcium carbonate, that can be easily applied to teeth without setting time, providing immediate relief and adherence.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If aqueous-based dental compositions are used for temporary tooth repair, then the composition can be easily formulated and applied, but it reacts prematurely, produces foul tastes, and creates rough textures
Solution Approach 1:
The patent changes the fundamental parameter of the base material from aqueous to non-aqueous (silicone rubber base). This parameter change eliminates the harmful reactions and sensory issues associated with aqueous formulations while maintaining ease of application. The silicone base does not react prematurely with calcium carbonate or other ingredients, preventing foul tastes and rough textures.
Solution Approach 2:
The patent creates a composite material system combining silicone rubber base with dry powdered ingredients (calcium carbonate, xanthan gum, arginine bicarbonate). This composite approach allows the non-aqueous base to prevent harmful reactions while the dry powders provide the necessary dental therapeutic functions, resolving the contradiction between ease of formulation and avoidance of harmful effects.
2Reliability
If traditional dental compositions are used, then they provide temporary repair functionality, but they require excessive wait times (1-3 hours) before eating
Solution Approach 1:
The patent changes the setting mechanism parameter from chemical curing (aqueous-based) to physical adhesion (silicone-based). The silicone rubber base material adheres to teeth through mechanical bonding and van der Waals forces without requiring chemical reactions that take hours to complete. This allows immediate use after application, eliminating the 1-3 hour wait time while maintaining reliable temporary repair functionality.
3Reliability
If complex instructions are provided for applying dental compositions, then the composition can be applied effectively, but the application process becomes difficult for laypersons
Solution Approach 1:
The patent segments the application process into a single simple step: apply the paste directly to the tooth. By eliminating the need for crown preparation, material manipulation, and multi-step procedures, the invention makes effective application achievable for laypersons while maintaining reliability through the superior adhesion properties of the silicone base.
Solution Approach 2:
The silicone-based composition is designed to be self-adhering without requiring complex preparation steps. The material automatically bonds to the tooth surface upon application, eliminating the need for users to perform delicate crown preparation or follow complex instructions, thereby enabling effective application by laypersons.
4Strength
If the composition is applied to a wet tooth, then the adhesion is improved, but the user must wait at least two hours before eating to allow the composition to set
Solution Approach 1:
The patent changes the adhesion mechanism parameter from chemical setting (aqueous-based) to physical bonding (silicone-based). The silicone rubber base material forms strong adhesion through mechanical interlocking and physical forces that are immediate upon contact with the wet tooth surface, eliminating the need for hours of chemical setting time while maintaining strong bond strength.

AI summary
A dental composition for the desensitization and covering of an area of a human tooth comprising a finger malleable base material made up of a product consisting of either: one or more hydrocarbon-based waxes, possibly with either or both of an organic filler and an inorganic filler, an uncured, uncross linked silicone high consistency rubber base; or a hydrophobic water insoluble solid material that is malleable at 37° C. or lower and safe for a human oral environment. The dental composition also includes a combination of dry, powdered materials dispersed on a tooth-engaging surface of the finger malleable base material. The combination of dry, powdered materials comprises a water-soluble polymeric adhesive and at least one dental tubule blocking agent or hypersensitivity desensitization ingredient.
