incisors and upper right ca- nine which he lost four years ago in a car accident. He was extremely disappointed with his acrylic denture and requested fixed prosthesis with life-like appearance. The patient rejected implants as being too expensive, however he stated it will remain his preferable option in future. At this stage we discussed minimally invasive bridges and the patient felt it was a right option for him. Our treatment plan consisted of traditional RBB to replace UR3 and a hybrid bridge to replace missing central incisors. Due to the small size of the UR3 pontic [width only six mm] we opted for cantilever design with full coverage of palatal cusp of UR4 to increase bond- ing area and rigidity. The preparation involved only light chamfer line. This bridge was fitted with Panavia [Kuraray Co], and no prepara- tion was made for UR2-UL2 bridge. Impressions, dyes and working casts were made using conventional methods and materials. The next step was to form a wax pattern with inner canal, which was filled with fibre-rein- forced composite core at the later stage. Small irregu- larities inside the canal will create additional mechanical anchorage. The wax pattern was converted to replicate in dental alloy using lost- wax technique and then por- celain was added and tried-in to ensure good aesthetic re- sult. Prior to glass fibre appli- cation Alloy primer [Kuraray Co] was applied to sandblast- ed metal surface to increase bonding strength of com- posite to dental alloy. At this stage we covered the labial wall of the inner canal with one mm of Gradia composite and light cured. Pre-cut single pre-impregnated fibre strip was inserted [Dentapreg PFU] and bonded to both ends with flowable composite [Filtek, 3M]. The outer layer of com- posite was built incrementally with Gradia. The strip must be com- pletely embedded in resin to protect glass fibres from oral exposure; the retainers were formed and light-cured using the same principle. Addition- ally, after shaping and finish- ing, the bridge can be placed into the light curing unit, eg.Dentacolor XS [Kultzer], for the final application of light to ‘At this stage we discussed minimally in- vasive bridges and the patient felt it was a right option for him’ 17ClinicalMarch 11-17, 2013United Kingdom Edition page 18DTà
