Frequently asked questions

How to value a dental practice in Nantes?

Standard: 30-60 % of average revenue (last 3 years), adjusting for: patient base age, demographic profile, equipment (CAD/CAM, panoramic, cone-beam scanner), commercial lease, staff, local competition. A shared-facility company with several practitioners is worth more.

Investment for an equipped practice?

160K €-530K € €: dental chair (15-50K), suction and compressor, autoclave, digital panoramic (15-35K), intraoral camera, optional cone-beam scanner (45-80K), CAD/CAM if prosthetics done in-house (60-150K), accessibility-compliant fit-out, furniture.

Which procedures are most profitable?

Off-schedule procedures with free pricing: implantology (1,200-2,800 €/implant), surgical periodontics, aesthetics (whitening 200-600, veneers 800-1,800/tooth), invisible orthodontics Invisalign (3,500-6,500). Account for 25-50 % of revenue in top practices.

Does the public-coverage package strongly impact profitability?

Yes: covered crowns and prosthetics have capped pricing, reduced margin 15-25 % vs 50-65 % on free-pricing class. Accounts for 30-50 % of prosthetic procedures. Offset by: aesthetics, implantology, adult orthodontics. Sharp product strategy and balanced patient mix preserve margin.
