ABSTRACT:
A method for reattaching to a first abutment tooth a detached crown of a dental bridge having at least one other crown fixed onto a second abutment tooth includes the steps of forming a vent hole through the detached crown, inserting the open tip of a syringe needle into the vent hole, preliminarily securing and sealing the needle in the vent hole and thereafter applying a flowable dental adhesive material such as an acrylic resin to securely reinforce the connection between the needle and crown and seal any gap therebetween. The void under the detached crown is then washed by ejecting fluids through the needle with a syringe barrel. A flowable dental cement is then ejected through the needle to fill the void between the crown and abutment tooth. Upon curing of the cement, the acrylic resin is dislodged from the surface of the crown enabling withdrawal of the needle from the vent hole which is then plugged.
The syringe apparatus of the invention includes a barrel and plunger coupled to a needle having exterior surface irregularities or prongs adjacent but spaced from the open tip of the needle so that they will be covered by the acrylic resin for securing the needle to the crown.
