Dental Tools TRIZ Cases

A dental drill tool channels desiccated gas through an annular passage to dry dentinal tubules during tooth removal.

A dental handpiece inner barrel enables 360-degree ultrasonic insert rotation via a dynamic seal system.

Longitudinal axial holes in the bur shank reduce rotational mass, increasing speed and cutting performance while extending handpiece lifetime.

A dental bur features an abrasive cutting section and a smooth rounded distal tip for bone preparation.

Alternating tooth sections on the milling head resolve the contradiction between rapid penetration and fine surface machining.

Grouping basic camera images into multiple phases and averaging them to suppress noise in phase-related images.

A subgingival safe end dental bur uses a spherical tip to trim composite resin margins below gum tissue.

Dimpled surfaces induce turbulence to prevent slurry separation, while a split housing wiper removes residue before ejection.

Angled fluid jets create helical flow patterns to rotate canal contents, removing tissue without damaging walls or forming smear layers.

Dynamic pulse width and frequency control enables selective caries removal without damaging soft tissues.

A surgical template positioning device uses three non-collinear spherical recesses and portions to define a spatial plane for accurate dental implant guidance.

A self-contained oral hygiene device combines a water pump with an abrasive powder supply system to deliver a pressurized cleaning mixture directly to teeth.

Raised polymeric fins scrub canal walls to eliminate the smear layer that inflexible files leave behind.

A movable air deflector delivers compressed air into a dental treatment reservoir to maintain abrasive fluid agitation.
