  • Process of electro-eroding channels in multiple buccal tube device
    Patent number: 4184254
    Abstract: A buccal tube device has a body attached to a tooth band. The body contains at least one channel with a non-circular cross-section. The channel is formed in the body by an electroerosion process. In a preferred form, the channel cross-section is four cornered and is inclined. The invention also includes a process for forming such buccal tubes by providing an electroerosion electrode with a non-circular cross-section and using it to form a channel of corresponding cross-section. The electroerosion process may include flushing the channel thus formed during the electroerosion.
