Abstract
A dental floss device with a guide post for removing food debris and dental plaque during orthodontic treatment. The guide post includes a guide post of a uniform small diameter and a floss bonded thereto. The guide post has a semi-spherical tip for sensing position to ease insertion of the guide post between the clearance which is formed by teeth and the orthodontic appliance. The dental floss device is formed by injection molding.
Claims3
A method for producing a dental floss device comprising the steps of:
- a) providing a mould having a cavity defining two guide posts, with each guide post having a tail end portion, a curvilinear front end portion terminating in a semi-spherical tip and a substantially constant diameter from the front end portion to the tail end portion, the two guide posts being tangential to each other at curvatures of the front end portions and on a parting plane of the mould, and the tail end portions extending longitudinally along a straight line;
- b) disposing a floss in the cavity;
- and
- c) injecting an encapsulating material into the cavity to encapsulate the floss and produce two dental floss devices, with each device including a guide post and a floss having a first end securely fixed to the tail end portion so that the entire guide post may be threaded through a gap formed between an orthodontic appliance and teeth to which the appliance is fixed to position the floss for flossing between the teeth.
