1. What a full practice purchase looks like
You buy 100% of an existing practice (or a startup, though that's a different path entirely) and become the sole owner from day one. You control every decision — clinical, financial, staffing — immediately, and you take on the full purchase price and full risk.
This suits dentists who know exactly what they want to build, don't need a transition partner, and are ready to run a business solo from the start.
2. What an associate buy-in looks like
You join an existing practice as an associate first, then purchase a percentage of ownership over time — often 50% initially, sometimes structured in stages. The seller (or a senior partner) stays involved, which smooths the transition for patients and staff and lets you learn the practice's operations before taking on full control.
Buy-ins are common in multi-doctor and specialty practices where an ongoing partnership, not a clean handoff, is the goal.
3. Risk and control trade-offs
Full purchase: higher upfront risk, but full control and full upside from day one. You're not sharing decisions or profit with a partner.
Buy-in: risk is often spread out (you may finance a smaller initial stake), and you get a built-in mentor/transition period — but you share control and profit with the other owner(s) until (and sometimes after) you reach full ownership.
4. Financing differences
A full purchase is typically financed as a single acquisition loan against the whole practice's cash flow. A buy-in is usually financed against the value of the percentage being acquired, which often means a smaller loan and lower monthly payment initially — though total lifetime cost depends on how the later buy-in stages are priced.
Both are financeable through the same lender pool (SBA 7(a) or specialty dental lenders) — see our financing guide for how that works.
5. How the partnership terms get set (buy-in specifically)
A buy-in needs a clear partnership or shareholder agreement up front: how the remaining stake is valued and purchased later, how major decisions are made while ownership is split, and what happens if either partner wants out. These terms matter as much as the initial price — have your own attorney review them, not just the seller's.
6. Which path fits which dentist
A full purchase tends to suit dentists confident in running a solo practice immediately, often in a general practice with a straightforward transition. A buy-in tends to suit dentists entering a specialty or multi-doctor group, or who want a mentor relationship and a gradual on-ramp to ownership and management responsibility.
