Abstract: Objective To observe the clinical effect of all-ceramic resin-bonded bridge made of hot-pressed casting porcelain with improved tooth preparation in patients losing one or two mandibular anterior teeth. Methods 32 patients received the treatment. 32 two-retainers all-ceramic resin-bonded bridges were made. The integrity of the restorations, secondary caries of the abutments and the shade in the margin of the retainers were observed at 3 months, 6 months, 1 year and 2 years after the treatment. Result No loose and break of the bonded bridges were found after 3 months and 6 months. One prosthesis lost bond after 1 year, and two prostheses lost bond after 2 years, but they still could be used after being re-bonded. No secondary caries on the abutment and shade in margin of the retainers were observed after 2 years. Their color matched the adjacent teeth excellently. The success rate was 90.6%. Conclusion All-ceramic resin-bonded bridge made of hot-pressed casting porcelain with improved tooth preparation can obtain good restoration effect in patients losing one or two mandibular anterior teeth.
