ProsthodonticsExplanation: The combination of acrylic resin posterior teeth and porcelain anterior teeth can lead to differential wear and stress concentrations, which may cause resorption of the anterior residual ridge. Porcelain teeth are harder and can create more stress on the underlying bone compared to acrylic teeth, leading to potential resorption. Therefore, option 2 is the correct answer, as it highlights the negative impact on the anterior ridge.

Conservative DentistryExplanation: When dealing with adjacent Class III cavities, it is generally recommended to prepare the larger cavity first and fill it last. This approach allows the dentist to have better access and visibility when preparing the larger cavity, which can be more complex. Filling the larger cavity last helps to avoid contamination and ensures that the smaller cavity can be filled with precision without compromising the integrity of the larger restoration.
