Dental Implants TRIZ Cases

Undercut dual-helical threads create bone interlocking spaces that resist multi-axial loading, improve load sharing, and reduce loosening.

A spherical grooved fastener head enables secure multi-angle driving in tight spaces while reducing stripping, corrosion, and removal issues.

Laser-formed trunk and branch pores help titanium-based implants precipitate calcium phosphate and achieve denser bone adhesion.

Enlarged abutment holes and a predesigned positioning guide let immediate dental prostheses fit implant shifts while preserving occlusion.

A ribbed lobular driver and tapered screw socket maintain friction attachment up to 25° while reducing edge stress and wear.

A lobular rib-and-core drive transmits torque up to 25° while reducing edge wear and retaining non-magnetic screws by friction.

An additive implant placement approach uses a guiding instrument and bone-implantable material to preserve bone strength and improve positioning accuracy.

Parabolic flute geometry increases bone chip space during drilling, cutting friction and thermal damage while preserving drill bit strength.

Web grooves remove dead metal at the drill tip, helping titanium dental drills cut bone while preserving biocompatibility and corrosion resistance.

A provisional prosthesis and 3D tomography guide implant drilling, enabling immediate permanent denture placement with high positioning accuracy.

Custom CAT scan-based implant guides and additive site preparation improve bone implant accuracy while minimizing tissue damage and graft use.

Functional bite mapping captures opposing arch motion to build an interference model for dental restorations with more accurate occlusal fit.

Pins, rotation stoppers, and a fitted reference recess orient denture abutment stock accurately before cutting to avoid misalignment.

Ultrashort polarized laser pulses form periodic zirconia surface microstructures that improve adhesion while avoiding phase change and cracking.

An intermediate layer joins porous prosthesis surfaces to the substrate, improving resistance welding while preserving scaffold integrity and bone ingrowth.

A 3D-modeled trimming guide converts patient anatomy into a flat membrane template, improving fit while limiting fibrous tissue ingrowth.

A single plate with shaped recesses and rotational locking positions different dental abutments precisely while cutting setup time and waste.

Femtosecond-laser nano-protrusions replace biofilm coatings on implant fixtures, improving bone bonding while reducing inflammation risk.

A molybdenum-rhenium alloy improves orthodontic device strength, radiopacity, fatigue life, and biocompatibility without added bulk.

A 3D-modeled trimming guide shapes PTFE regeneration membranes to fit bone defects, improving handling while limiting fibrous tissue ingrowth.

Built-in mounting features let additively manufactured parts be fixtured accurately for finish machining, cutting probing time and material waste.

A pin-and-engagement holding attachment fixes denture abutment material orientation before cutting, reducing misalignment and improving machining accuracy.

A form-fitting retainer holds the abutment blank away from the implant interface to reduce machining vibration and preserve seating accuracy.

An awl drill lance and end mill blade flatten thin ridge alveolar bone before hole formation, reducing slip and improving implant placement accuracy.

A hexalobular screw profile raises dental implant screwing angles to 35° while reducing driver decoupling, wear, and misalignment.

Angled recesses and a tapered polygonal driver let dental screws be inserted and rotated through angulated implant channels with less slippage.

A parabolic cross-section and fast helix angle open more flute space for bone chip removal, cutting friction and drilling heat.

Optical reference marks and laser targets locate the AM building platform within scanner coordinates for sub-50 µm alignment and repeatable reuse.

Pre-alloyed NiTiHf powder and post-build aging raise AM medical component strength while keeping residual set below 2% after 6% strain.

Built-in kinematic mounting features let additively made parts be fixtured accurately for subtractive finishing of supported surfaces.
