If a patient is missing teeth #2 and #3, and #1 is in occlusion with #31 or #32, which treatment option is most appropriate?

The most appropriate treatment option in the scenario where the patient is missing teeth #2 and #3, and tooth #1 is in occlusion with #31 or #32 is a fixed partial denture, particularly for the configuration of #1-x-x-4-5. This option serves to replace the missing teeth while providing stability and a fixed solution for the patient.

A fixed partial denture, commonly known as a dental bridge, is ideal in this situation because it utilizes the existing tooth #1 as the abutment anchoring the missing teeth, thereby restoring function and aesthetics effectively. This approach allows for better maintenance of the dental arch and occlusion, distributes the forces of occlusion more evenly, and does not require invasive procedures such as extraction of functional teeth.

Moreover, it avoids the potential complications that can arise from the extraction of tooth #1 and subsequent efforts to replace the missing teeth with implants or removable prosthetics. A fixed bridge promotes better patient compliance, as it is a permanent solution, reduces the risk of loss of adjacent teeth, and tends to be more comfortable for the patient compared to removable options.

While other treatment options may offer viable solutions, they are either more invasive or might not serve the patient’s needs as effectively.
