Rotary dental abrasive polishing applicator

A polishing applicator tool for power rotary dental handpieces for application of an abrasive polishing composition containing non-fixed abrasive particles to teeth and tooth restoration materials comprising;

• a) an integrally formed, one piece cylindrical shaft having a first polishing end portion for carrying said polishing compound and an opposing end portion conformed for cooperative demountable attachment to said rotary dental handpiece for rotation about the axis of said shaft, said shaft and said polishing end portion being formed of a plurality of fibers having a hardness value less than the materials to be polished and aligned in parallel relationship along their axial length and adhesively bound together, said polishing end being ground to a predetermined generally conical configuration including a microscopically porous surface configured to retain said polishing compound in operative relationship between said porous surface and the tooth materials being polished.

A method for abrasively polishing the surface of teeth and tooth restoration materials comprising forcing a diamond containing polishing composition against the surface of the tooth or tooth restoration material with an applicator having an outwardly extending polishing tip integrally formed in one piece on a generally cylindrical shaft portion with the opposing end of said shaft portion removably mounted to a rotary dental handpiece, while maintaining a rotational speed of said applicator relative to said surface of the tooth or tooth restoration material above about 1000 revolutions per minute and a loading pressure sufficient to remove materials from the surface of said tooth or tooth restoration material;

• said shaft and said polishing tip comprising a synthetic material formed from a multiplicity of elongated fibers aligned in parallel relationship to one another and adhesively fixed together in along their axial length and said polishing tip having a porous surface and an inherent capillary-type fluid transfer capability.

A polishing applicator tool for power rotary dental handpieces to apply a polishing composition containing non-fixed abrasive particles into polishing engagement with teeth and tooth restoration materials comprising, in combination;

• a) a generally cylindrical connecting portion having one end conformed for releasably fixed connection to said rotary dental handpiece for rotation about the axis thereof and an opposing end provided with a tubular socket portion;
• b) a polishing applicator tip removably inserted into said socket portion including a one piece integrally formed cylindrical shaft having a first polishing end portion for receiving said polishing composition and an opposing second end portion conformed to be disposed in a removably fixed relationship to said tubular socket for rotation with said connecting portion, said shaft being formed of a plurality of fibers having a hardness value less than the tooth materials being polished and aligned in parallel relationship to the axis of rotation of said shaft and adhesively bound together, said polishing end portion being ground to a predetermined configuration and including a microscopically porous surface configured to retain said polishing composition in operative polishing relationship upon rotational engagement with said materials being polished.
