What this specialty covers
That branch of dentistry pertaining to the restoration and maintenance of oral functions, comfort, appearance and health of the patient by the restoration of natural teeth and/or the replacement of missing teeth and contiguous oral and maxillofacial tissues with artificial substitutes.
Reading the sole-proprietor share
For Prosthodontics, the 34.6% figure is the share of active primary-taxonomy records flagged as sole proprietors, not a direct count of private practices. The flag is a self-reported NPPES field and is an imperfect proxy because it does not by itself establish ownership, employment arrangement, practice size, or independent operation.

Data notes
- The sole-proprietor field is self-reported by the provider in NPPES and is an imperfect proxy for private practice.
- A sole-proprietor count shown as <11 is suppressed: the true value is below 11, which could include zero.
- NPI records are administrative identifiers and may not equal unique clinicians, practices, or current patient-facing availability.
- The primary taxonomy reflects the classification on the NPPES record and may not capture every clinician who provides prosthodontic services.
- Providers are counted once, by their primary taxonomy code only.
