A breakdown of how ownership structures differ, from independent practice to investor-owned networks, and what each one means for autonomy, equity, and support.
“Ownership” used to mean one of two things for an orthodontist: you owned your practice outright, or you sold it and became someone else’s employee. That binary has quietly disappeared. Today, an orthodontist deciding how to structure their career, whether fresh out of residency or three decades into a solo practice, is choosing among several distinct orthodontic practice ownership structures, each with a different answer to who holds equity, who makes decisions, and who ultimately profits when a practice does well.
Understanding the full range of orthodontic practice models matters more now than it did a decade ago, because the distance between the right fit and the wrong one has widened considerably. Below is a breakdown of the four main types of orthodontic practice ownership: independent, group, partnership OSO, and investor-owned, along with what each one means for autonomy, equity, and support.
Doctor-Owned / Independent Practice: Full Autonomy, Full Responsibility
The independent practice is orthodontics in its most traditional form.
One doctor owns 100 percent of the entity, makes every clinical and business decision, and keeps every dollar of profit after expenses. There is no partner to consult before changing a vendor, adjusting a fee schedule, or bringing on a new associate.
That autonomy comes bundled with responsibility.
Payroll, lease negotiations, equipment financing, marketing, HR compliance, and every operational headache in between rests with one person. Independent owners also carry the growth ceiling that comes with limited purchasing power and no built-in peer network: there is no group of colleagues down the hall to benchmark against or lean on when a hard case, a staffing crisis, or a succession question comes up.
This model tends to suit doctors who want total control and are equally comfortable running a business as they are treating patients. It is a less common ownership structure among orthodontists just beginning their careers, and the one most often reconsidered as an owner approaches retirement and starts thinking about transition.
Group Practice: Shared Resources Among Doctors, Without Giving Up Individual Ownership
A group practice brings multiple doctors together under one roof or one administrative structure.
They typically share overhead, including staff, equipment, leases, marketing spend, and on-call coverage. Ownership in a group can take a few forms. Doctors sometimes retain fully separate ownership of their own patient panels while splitting shared costs, and other times they hold partial ownership in a single group entity alongside their colleagues.
The appeal of independent orthodontic practice vs group practice comes down to leverage without dilution.
A group can negotiate better supplier pricing, cover for each other during vacations or emergencies, and offer newer doctors informal mentorship, all while each doctor keeps a meaningful ownership stake. What a group practice does not typically provide is outside capital or centralized, professional back-office support. Growth is still self-funded, and decisions that affect the whole group still require the whole group to agree, which can slow things down as the number of partners increases.
Partnership OSO Model: Doctor Equity Retained, Centralized Support Added
An orthodontic service organization, or OSO, sits between a group practice and a fully investor-owned network.
An OSO layers centralized administrative support, such as HR, marketing, purchasing, and back-office systems, on top of individual practices, while clinical decision-making and a substantial share of equity remain with the doctors themselves. The distinction that matters most in the partnership OSO model is degree: how much equity and governance authority doctors actually retain once they join.
Corus Orthodontists is one example of this model in practice.
Founded in 2019 by a group of 18 orthodontists,¹ Corus has grown into a network of 65+ Doctor-Partners across 55+ practices in 80+ locations spanning 13 U.S. states and 5 Canadian provinces.² Doctors who join become shareholders, not employees. They receive a cash component at the outset of partnership, retain equity in a diversified portfolio of practices across the network, and continue to lead their own patient care and, generally, their own practice for years after joining.¹
The positioning Corus uses for this is deliberate: buy in, not sell out.
Rather than trading a practice for a payout and stepping back, doctors in this model add a support layer while keeping a genuine ownership stake and a voice in how the organization is run, including doctor-led governance structures like board seats and doctor subcommittees.¹ Corus also works with newly joined practices to improve operations, often training and retaining existing staff on updated technology and processes rather than replacing the doctor’s clinical judgment or the team already in place.
That team-continuity piece is central to how this model is meant to function over time. Because the goal is long-term growth rather than a short ownership horizon, the incentive moves us toward investing in and hiring for a practice rather than trimming it to look maximally profitable ahead of a resale.
Investor-Owned Network (DSO/PE-Backed): What Changes When Outside Capital and Control Enter the Picture
An investor-owned orthodontic network, generally structured as a dental support organization backed by outside capital, works differently at its foundation.
Outside investors provide capital in exchange for ownership, and doctors who join often become employees or join a group of minority equity holders. Non-clinical decisions are set at the corporate level rather than in your office.
The advantage of this model is speed and scale.
External capital allows rapid expansion through acquisition, and it can offer a doctor a large portion of their practice’s value through liquidity, as well as relief from administrative burden. The tradeoff is reduced day-to-day autonomy and an equity position in the parent company (the buyer) that is usually smaller and less durable than what a founding or partnership-model doctor would hold.
Doctor-owned vs private equity orthodontics also differs in time horizon.
Investor ownership can come with a defined hold period before the business is sold again to the next investor, re-capitalized with new debt, or taken public, which means decisions about staffing, technology, and growth are shaped by that eventual exit rather than by a single doctor’s multi-decade view of their own practice. For a doctor who is ready to step back and who prioritizes liquidity over continued equity building, this can be a good fit.
For a doctor who wants to keep shaping the practice they built, it is worth understanding clearly before signing anything.
Comparing the Four: Autonomy, Equity, Support, and Who Ultimately Profits
Laid side by side, the four orthodontic practice models explained above sit along a spectrum, from total control and total risk on one end to total support and reduced ownership on the other.
| Model | Autonomy | Equity | Support & Who Profits |
|---|---|---|---|
| Independent | Full clinical and business control | 100 percent, undiversified | Minimal, self-managed; doctor keeps all profit and bears all risk |
| Group Practice | High, shared major decisions with partners | Individual or partial ownership retained | Shared overhead and coverage; profit split by group agreement |
| Partnership OSO | Clinical autonomy retained; admin and tech are centralized | Majority held by doctors, often diversified across the network | Back-office, marketing, HR, and peer network; doctors typically share practice-level profits with the network and convert their shares to cash over time |
| Investor-Owned | Reduced; corporate-level decisions | Minority or no ongoing equity for the doctor | High, centrally directed support; corporate sponsors usually see most of the upside and hold the highest class of shares |
The differences here are not only about who signs the checks. They are about where a doctor wants to sit between total control and total support, and how long they intend to be part of the practice’s story once the decision is made.
Finding the Right Fit
No single ownership structure is right for every orthodontist, or for the same orthodontist at every career stage. A newer graduate might value mentorship and reduced financial risk over full autonomy. A mid-career doctor might want operational support without giving up equity. An established owner nearing transition might prioritize preserving their legacy and keeping their team intact more than maximizing a sale price. The starting point is the same for all three: understanding what each model actually offers, and being honest about which tradeoffs matter most right now.
Corus Orthodontists: A Unique OSO Model
Corus is a partnership OSO built and led by orthodontists. Doctor-Partners join as shareholders, not employees, keeping clinical autonomy and a real equity stake while gaining centralized support and a peer network across the U.S. and Canada.
