title: [A metal-free single sitting fibre-reinforced composite bridge for tooth replacement using the EOS-System].
abstract: This paper intends to introduce a technique for a one sitting fixed resin bridge with excellent aesthetics and longevity. Techniques using denture teeth or a crown portion of the patient's own teeth have already been presented by many authors. But they all have been unpredictable and their longevity could not be assured. The addition of resin fibre filament to create a flexible reinforcement at the pontic-abutment interface gives added strength to the acid etch bond between pontic and abutment. Reinforcing systems such as metal wires, woven screen, metal bars with retentive holes, glass fibres, silk and resin fibres have been used with varying results. The original composite reinforced bridge using resin fibres was done by the author with Kevlar 49 in February of 1981, replacing both upper central incisors using only the lateral incisors on a 22 year-old female. This four-unit-bridge is still in function (end of 1989) and has never been replaced or repaired. Since then improvements have been made and the following technique has evolved. 360 fibre reinforced "Belvedere bridges" have been placed to date with a success rate of 98%. One of the improvements is the use of another fibre, which has extremely high tensile strength: it is a polyethylene fibre, colourless and six times stronger than steel.
