Abstract
The practical combination of the potential of bonding systems, composite materials and synthetic fibres opens up new possibilities for the restoration of qualitative and quantitative deficiencies. The use of a fibre filler significantly changes the mechanical properties of the composite material. This study presents the restoration of missing tooth 24 with a fibre-reinforced composite bridge. As a bridge pillars were used: tooth 23 – after endodontic treatment and tooth 25 – with preserved vitality and fixed filling covering the proximal wall and chewing surface. The work was carried out by direct modelling in the oral cavity. The restoration was made from two different types of composite material: a light-curing and a light-chemically-curing dual-activation polymerisation system. The materials use a different filler and matrix. The structure was reinforced with 16,000 glass fibres arranged in parallel. Systematic check-ups and periodic prophylactic treatments avoided complications and preserved function over a 15-year follow-up time. The methods and materials used allowed to achive permanent adhesion and functional-aesthetic restoration of the quantitative deficit of 24 and qualitative deficiencies of teeth 23 and 25. Fifteen years of observations confirmed the effectiveness and durability of the used solution.
