I could not disagree more.
While dentures are somewhat archaic and not sexy compared to fixed ceramo-metal restorations, denture therapy will have a significant place in any general dental or prosthodontic practice. Denture fabrication, treatment planning, and impression technique have a critical role in implant restoration.
It's not even a function of finances many times, what do you do if a patient has a severely resorbed anterior maxilla, high lip line, loss of facial & lip competence?
Sure you can prescribe fixed ceramo-metal restorations but what will you say when the patient says they don't like the look of how the pink porcelain and their own gingiva comes together? Maybe they don't like crowns that are 20mm in height? What are you going to do?
Everything else requires some sort of denture to transition to restoration. Hybrid prosthesis? Denture teeth are used and requires interim denture for diagnostic steps. Spark-erosion prosthesis... yup, denture. Nobel all-on-four prosthesis? yup, denture.
Overdentures are great, especially with 4 implants and removing a palate, but what's wrong with a maxillary CD w/o implants? Patients can get very comfortable with them and are very predictable. Maxillary CD or overdentures are excellent restorations of choice with the aformentioned patient.
Mandibular dentures, however, are terrible by themselves without retention... if your comment was directed to this type of prosthesis, maybe I could buy your statement.
