Teeth Filling TRIZ Cases

A dental file guide tip reduces contact area via non-uniform face surfaces, minimizing resistance and breakage risk during root canal shaping.

Dentine projections scatter light through the tooth structure, preventing a washed-out appearance while maintaining manufacturing simplicity.

A unit dose package with a rotatable discharge conduit manages fluid flow communication between storage compartments and orifices.

A composite liquid agent package joins separate pouches using extruded sealants that fuse into a binding portion.

Water-impermeable sealing prevents water-soluble selenite from dissolving in oral fluids while maintaining structural integrity.

A frustoconical spacer with a cylindrical recess secures an endodontic instrument stopper to fix penetration depth.

A custom mouthpiece uses a connector and shim system to align incisor edges precisely.

An electric linear actuator replaces hand actuation in a composite extraction pen, eliminating operator shake and improving delivery precision.

Clear tips transmit curing light while holding restorations, preventing shift during polymerization.

A single-use packaging system with a rigid housing and separating membranes stores multi-component materials in isolated regions until activation.

A dental image display device overlays two-dimensional visible light images with three-dimensional root canal data on a single monitor.

A flexible circuit board supports UV LED arrays in an intra-oral mouthpiece to deliver targeted light for teeth whitening.

Nested ultrasonic tip assembly delivers multi-planar vibrations to agitate irrigants and remove debris, resolving limited insertion depth in root canal therapy.

A universal dental arch frame adjusts jaw position via a flexible tension element, reducing laboratory time loss while treating snoring.

Variable taper threads and cut sections remove dentin debris efficiently, reducing blockage and instrument breakage risks.

A root canal marker uses spring-biased jaws to grip soft gutta percha points, allowing a sliding shaft to move an applicator for precise length marking.

Optical alignment devices project reference lines to guide sensor positioning, resolving inconsistent perspectives that hinder accurate dental change analysis.

Segmenting the retractor and illuminator into separate modules reduces sterilization costs and prevents thermal damage to oral tissue during dental procedures.

Segmented barrel and tip design minimizes waste and cross-contamination by supporting extruded material on a platform.

Coating fillers with a silica heteropolycondensate prevents ion diffusion and insoluble salt formation, maintaining storage stability.

Heat treatment at 400 to 430 degrees Celsius tempers nickel-titanium alloy working areas, resolving flexibility and mechanical stability trade-offs.

A tapered ovate saliva ejector uses arced passages to remove fluid along the buccal mucosa.

A dental capsule uses a separable valve and piston to mix materials.

Ball pivots in recessed seats replace external snap-fits, resolving discomfort and mobility limits while enabling user-adjustable link lengths.

An adjustable bifurcated pad assembly provides isotonic resistance training for facial muscles.

A radially emitting laser fiber delivers electromagnetic radiation to disinfect root canal tissues and dentinal tubules.

Projected ribs support a cylindrical tube member to minimize remaining drug amount while maintaining mold durability and sufficient neck strength.

Offset light arrays on the mouthpiece direct illumination onto specific tooth rows, resolving uneven coverage caused by varying dental arch dimensions.

A three-layer mouthguard uses air cushions between a rigid base and soft outer layer to dissipate impact forces.

A conical dental bur with a tapered shank enables precise pulp chamber access.

A frangible mixing container uses a stepped compression zone to control plunger movement, preventing uncontrolled extrusion of low viscosity dental materials.

A dental clamp retractor integrates buccal and lingual gauze holders via flexible arms to retract soft tissue.

A radio-opaque identification tag bonded directly to a tooth surface enables rapid visual detection via standard radiographic imaging.

An implantable structure stabilizes tongue orientation to maintain airway patency, avoiding CPAP discomfort.

Segmented anchoring members and nested tubes deliver controlled saliva flow, resolving comfort trade-offs in oral replenishment devices.

Concentric cylinders protect the applicator while a frangible film seal prevents material splashing during opening.

A multilayer planar antenna integrates with the contra-angle head to enable contactless RFID data exchange between the dental tool and handpiece.
