Medicament Tooth Covering With Water-Activated Sustained Release

Solution Overview

Problem

Conventional methods for delivering dental medicaments, such as strips, braces, or trays, require frequent recoating and cannot provide long-lasting, uninterrupted dental care due to their temporary effectiveness.

Innovation Solution

A medicament delivery tooth covering with a carrier layer that carries dental care agents, allowing medicaments to be directly applied to teeth via contact with water, utilizing a gel, sintered material, or porous film to release active ingredients like calcium ions for remineralization, whitening, and desensitization.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Duration of action of moving object

If conventional strips, braces, or trays are used to deliver medicament, then the medicament can be delivered to teeth, but the function can only be maintained for a short period of time and requires frequent recoating

Engineering Contradiction:

Improveduration of medicament deliveryVSAvoidconvenience of use

Core Design Contradiction:

Duration of action of moving objectVSEase of operation

Solution Approach 1:

The medicament is pre-loaded into the reservoir of the tooth covering in a ready-to-use form. The reservoir is prepared in advance with the medicament contained within, eliminating the need for frequent recoating operations. Users simply need to activate the reservoir by introducing water, which automatically releases the pre-positioned medicament to the teeth.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The tooth covering maintains continuous medicament delivery through a reservoir system that can be activated on demand. Once activated by water introduction, the reservoir continuously releases medicament over an extended period, providing uninterrupted dental care effect without requiring removal and recoating between applications.

Inventive Principle:

Principle #20Continuity of useful action

2Reliability

If conventional strips, braces, or trays are used to deliver medicament, then the medicament can be delivered to teeth, but frequent removal and recoating is required

Engineering Contradiction:

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The medicament is pre-loaded into the reservoir of the tooth covering in a ready-to-use form. The reservoir is prepared in advance with the medicament contained within, eliminating the need for frequent recoating operations. Users simply need to activate the reservoir by introducing water, which automatically releases the pre-positioned medicament to the teeth.

3Duration of action of moving object

If powder particles with core-shell structure are used, then controlled release of calcium ions is achieved, but the complexity of medicament formulation increases

Engineering Contradiction:

Improvesustained release of medicamentVSAvoidcomplexity of powder particle structure

Core Design Contradiction:

Duration of action of moving objectVSDevice complexity

Solution Approach 1:

The powder particles utilize a core-shell structure where the shell contains porous characteristics that allow controlled diffusion of calcium ions. This porous structure enables sustained release by regulating the transport of active ingredients from the core through the shell to the external environment, achieving extended medicament delivery without requiring complex mechanical or electronic release mechanisms.

Inventive Principle:

Principle #31Porous materials

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

The tooth covering provides sustained dental care effects by continuously delivering medicaments, enhancing remineralization, whitening, and desensitization through a controlled release of calcium ions from dual-structured powder particles.

Implementation Method 1

When water is introduced to an inner side of the at least one attachment surface of the tooth covering, the water is allowed to pass through the carrier layer, so that the medicament contacts the water

Methodology Applied

Scientific EffectPermeation: Permeation

Implementation Method 2

the carrier layer is a gel layer that is coated on the at least one attachment surface, and the medicament is mixed in the gel layer

Methodology Applied

Scientific EffectAbsorption: Absorption (physical)

Implementation Method 3

the carrier layer is a porous sintered material layer that is formed by sintering a particle material, and the medicament is mixed in the particle material

Methodology Applied

Scientific EffectPorosity: Porosity

AI summary

A medicament delivery tooth covering is provided. The medicament delivery tooth covering includes a tooth covering and a carrier layer. The tooth covering has at least one attachment surface that covers a surface of teeth of a user. The carrier layer is arranged on the at least one attachment surface. The carrier layer carries a medicament, and the medicament contains powder particles. When water is introduced to an inner side of the at least one attachment surface of the tooth covering, the water is allowed to pass through the carrier layer, so that the medicament contacts the water. The powder particles are dual-structured powder particles that have a core structure and an outer layer structure that encloses an outer side of the core structure.
