When does a general dentist refer to a prosthodontist?

General dentists refer to a prosthodontist when a case exceeds restorative scope: full-arch rehabilitation, complex implant prosthetics, severe tooth wear requiring full-mouth reconstruction, congenital conditions like ectodermal dysplasia, maxillofacial defects, or anterior esthetic cases where shade and contour to...

THE SHORT ANSWER

THE FULL PICTURE

Why it works this way

The referral triggers most general dentists recognize

The American College of Prosthodontists (ACP) published referral guidance in 2023 listing six categories that typically move a case from general restorative care to specialist prosthodontic care: full-arch rehabilitation, complex implant prosthetics (four or more units, zygomatic cases, or compromised bone), severe tooth wear with vertical dimension loss, congenital conditions, post-oncologic or trauma reconstruction, and high-stakes anterior esthetics. A 2022 Journal of Prosthodontics survey of 412 general dentists found that 68% refer at the treatment-planning stage rather than mid-case, citing prosthetic complexity and esthetic risk as the top two triggers.

What is the difference between a prosthodontist and a general dentist for a full-arch case?

Prosthodontists complete three additional years of ACP-accredited residency focused specifically on prosthetic reconstruction, occlusion, and implant prosthetics. On a full-arch case the prosthodontist typically owns the treatment plan, the provisional sequence, and the final prosthetic design, while the surgeon places implants and the lab fabricates the components. A general dentist can co-treat or refer entirely depending on case complexity, bone quality, and the patient's esthetic demands.

Does the lab change when the case moves to a prosthodontist?

Sometimes, but it does not have to. Many prosthodontists maintain working relationships with two or three labs and select per case based on the workflow required, monolithic zirconia, layered ceramic, or printed try-ins. If the referring general dentist's lab already handles full-arch and complex implant prosthetics with documented case planning, the prosthodontist will often continue with the same lab to preserve continuity on shade, contour, and provisional data.

How long does a typical prosthodontic full-mouth case take?

Full-mouth reconstruction with implants generally runs 6 to 12 months from initial consult to final delivery, per the 2023 ACP clinical guidance. The variation depends on whether bone grafting is required, healing intervals between surgical and prosthetic phases, and the number of provisional iterations needed to confirm vertical dimension and esthetics. Labs that batch full-arch cases and maintain dedicated technician assignment compress the prosthetic phase meaningfully.
