Fixed partial denture (FPD) prostheses restore esthetics and function by connecting and fixing to adjacent teeth. Conventional FPDs require, for better retention and resistance, extensive preparations. Those preparations include buccal, palatal or lingual coverage, proximal guide planes, chamfers and /or grooves to optimize retention.1–4 The removing of such large amount of tooth structure increases the risk of periodontal complications and pulp exposure.1,3 In 1973, Rochette introduced resin bonded FPDs as a less invasive therapeutic option. He pioneered the use of lingual perforated cast alloy framework with acid etch composite for periodontal splinting of the anterior region.5 However, early Rochette bridges presented high failure rates. Since then, resin bonded FPDs have evolved with different framework materials and designs. Even though metal frameworks are highly resistant, they do have esthetical and mechanical limits such as the greyish appearance of the abutment teeth an
