Dental Attachment Permanent Neodymium Magnets

Dental magnetic attachment is a device, utilizing magnetic force to fasten and stabilize false tooth to abutment or dental implant. It contains two parts: magnet and armature.

The first generation magnet used on dental attachment is samarium cobalt magnet. With the research and production of new super-strong permanent magnet, so in clinical practice at present, the main magnet for dental equipment is sintered neodymium iron boron magnets. There are alnico and ferrite magnet, why we don’t choose. That’s because the small dental attachment needs small magnet and this tiny magnet must have very strong magnetic force. However, the magnetic force of small alnico and ceramic is too weak to generate enough connecting force. Sintered NdFeB magnet has very high magnetic energy product and coercivity. Even if the size is very small, it can attract object several times heavier than itself. It is ideal accessories for dental apparatus.

Not only dental attachment need magnet, many other dental devices, such as articulator can use permanent ferrite magnet and rare earth magnet. China Magnets Source Material Ltd manufactures high quality permanent magnets for all kinds of dental devices. If you need custom dental magnet, please feel free to contact us.
