Dental Aids TRIZ Cases

A removable activator and compact tensioner tighten and release a circumferential matrix band with less oral cavity intrusion and discomfort.

Thin butterfly wings and a central contact section let dentists fill two adjacent teeth at once while maintaining tight contacts and easier handling.

A pull-tab elastomeric wedge elongates between adjacent teeth to push and hold the matrix tightly for complete cavity fillings.

An inverted-V Mylar band follows tooth contours to stabilize filling material, improve gingival sealing, and reduce voids during curing.

A concave ridge creates broader, tighter contact with adjacent teeth, helping limit food entrapment and support stable dental restorations.

Merging a wedge and matrix band reduces parts from nine to three, improving tooth contact and preventing leakage.

A resilient body member with pivotally coupled lugs applies clamping force to secure a dental matrix band around a tooth.

A pivoting device uses mating male and female heads to form a broad, flat contact surface on matrix bands, preventing breakage from unstable rounded points.

An elastic matrix system with circular rims and a sleeve adjusts diameter to fit posterior teeth.

A hollow dental wedge uses translucent walls to transmit curing light while a collapsible tip absorbs insertion force.

Segmenting the tensioner from the retainer allows removal after tightening, reducing interference during restoration.

A flexible elastic matrix band with an internal ridge self-stabilizes around a tooth to isolate fluids and prevent bonding material adhesion.

A spring-tensioned dental separator device with angled tines and a contoured matrix band stabilizes the interdental space for restorative procedures.

A foldable dental dam frame uses a magnetic sensor holder to stabilize X-ray sensors intraorally without removing the isolation barrier.

A face mask shield device integrates a dental dam frame and membrane to provide comprehensive facial protection for dental procedures.

Segmented anatomic matrices eliminate manual conformation time while ensuring seamless adhesion and durable composite fillings.

Segmented wings on a dental wedge conform to interproxial spaces, resolving the trade-off between sealing capability and structural simplicity.

An optically transmissive dental matrix band resolves light blockage by transmitting curing light through coated slots and plates.

Nickel-titanium wedges expand in warm interproximal spaces, separating teeth and securing matrices without complex multi-device setups.

A dental matrix band uses a movable toggle to adjust its looped circumference for precise tooth fitting.

A dental dam membrane and clamp arrangement formed from shape memory polymer featuring a slidable guide formation for secure positioning.

Curved terminus ends on the occlusal ring allow arms to engage buccal and lingual surfaces, resolving interproximal space maintenance issues.

A dental matrix band features a three-dimensional contoured surface with a flattened region to provide stable contact against adjacent teeth.

Eight independent hands on a flexible ring adapt to varied tooth contours, ensuring effective separation and preventing unhygienic marginal ridges.

A dental matrix clamp features a rotatable head and removable implement for precise band shaping.

Movable tines adapt to tooth contours, resolving the trade-off between separation force and structural complexity in dental restorations.

An inflatable dental matrix seals tooth anatomy to retain restorative material, preventing gum irritation from rigid clamps.

A cervical matrix uses a light-absorbing outer layer to accelerate curing.

Wireless power transfer eliminates sterility-compromising wires while the integrated LED cures composite resin in inaccessible gingival areas.

An integrated spindle mechanism tightens the matrix band within a compact housing, eliminating external tensioners that restrict dental restoration procedures.
