Which situation indicates the need for prescribing fixed prosthodontics?

Prescribing fixed prosthodontics is indicated primarily when there are sufficient abutment teeth present. Abutment teeth serve as the supporting structures for a fixed prosthesis, such as crowns or bridges. These teeth need to be structurally sound and adequately positioned to support the prosthetic device effectively. If the abutment teeth are viable, this allows for the creation of a stable and functional restoration that can improve the patient's ability to chew, enhance aesthetics, and provide long-term success.

The presence of severe tooth sensitivity may warrant treatment, but it does not in itself necessitate fixed prosthodontics. Current periodontal disease could complicate treatment as it may compromise the health of both natural teeth and any prosthetic restorations. Similarly, excessive caries activity would need to be addressed first, as untreated decay can undermine the integrity of potential abutment teeth. Thus, while these conditions could direct treatment efforts, they do not specifically indicate the need for fixed prosthodontics, highlighting why sufficient abutment teeth are a vital prerequisite for this type of restorative procedure.
