    Oral rehabilitation in fixed prosthesis treatments with metal-ceramic materials is widely used today, but these materials can fracture due to multiple factors. However, this situation does not always lead to replacement. Repairing porcelain with composite resin is an alternative with advantages such as easy handling and low cost. The main objective of this thesis was to determine the effectiveness of adhesion of three types of composite resins used as alternatives for repairing porcelain in fixed prostheses in Lima, 2019. This study was experimental, analytical, prospective, and cross-sectional. Feldspathic ceramic IPS CLASSIC V was used as the base material to evaluate the adhesion of three types of composite resins: Master Fill resin, Tetric N-Ceram resin, and Filtek Z350 XT resin. The microtensile bond strength (μTBS) was evaluated using a digital universal testing machine CMT-5L, LG, at a speed of 0.5 mm/min. The results showed that Filtek Z350 XT resin had the highest average adhesion level with 11.32% Mpa, Tetric N-Ceram resin achieved a regular level of 10.17%, and Master Fill resin showed the lowest level with 8.32% Mpa.
