The volume at which a general practice should stop referring implant cases and bring in a surgeon, the three models for doing it, what each costs and returns, the referral relationships worth keeping regardless, and the mistakes that turn a good associate hire into a bad year.
A general practice reaches a point where the implant cases it refers out add up to more than a full surgical day a month, and the owner starts to wonder whether that day should happen under their own roof. The options are to learn the surgery themselves, to bring in a surgeon part-time, to hire a full-time associate, or to keep referring and stop wondering. Each is right for some practices, and the volume, the owner's interests, and the practice's capacity decide which.
The mistake most practices make is treating this as a hiring decision when it is a capacity decision. An associate surgeon adds a salary, a surgical operatory, sedation, equipment, and a coordinator's workload, and produces a return only if the practice can feed them cases. A surgeon with an empty schedule is the most expensive employee in the building.
This guide lays out the models, the numbers, and the sequence.
At what volume should a practice stop referring implants out?
When the cases referred in a month would fill a surgical day, and when the practice is confident it can keep generating that volume. Below that, the fixed costs of bringing surgery in-house exceed the margin on the cases. Above it, the practice is sending its most valuable procedures to someone else and often losing the patient's restorative work along with them.
Counting the referrals
Most practices do not know how many implant cases they refer. Start by counting for three months: single implants, multiple implants, and full-arch consults, with the estimated fee for each. The total is the revenue the practice is choosing not to earn, and it is usually larger than the owner guessed.
What comes back
A single-implant referral usually returns to the general dentist for the crown. A full-arch referral often does not return at all, because the surgeon or a partner prosthodontist restores it. The patient-facing guide to what a prosthodontist does describes the restorative half from the patient's side, and a general practice referring full arches is usually losing both halves.
What are the three models for bringing surgery in-house?
The owner learns to place implants, a surgeon comes in part-time on a set schedule, or the practice hires a full-time associate surgeon. They differ in cost, in commitment, and in how much of the case the practice keeps.
The owner learns
The lowest fixed cost and the longest ramp. The guide to adding All-on-4 to a general practice covers the training, the mentored cases, and the equipment. It suits an owner who wants to do surgery and has years to build competence. It does not suit an owner who wants the revenue but not the work.
The traveling surgeon
An oral surgeon or periodontist who works in the practice one or two days a month, on a per-case or per-day arrangement, using the practice's operatory and staff. The practice keeps the patient and the restorative work, pays for surgery only when it happens, and takes no salary risk. It suits a practice with a surgical day a month of demand and no desire to hire. The limit is the surgeon's availability and the practice's dependence on one person's calendar.
The full-time associate
A salaried or production-based surgeon who works in the practice most days, builds the implant program, and often brings referral relationships with them. The highest return at high volume and the highest risk at low volume. It suits a practice with several surgical days a month of demand, or a plan and budget to generate it. The guide to the DSO decision describes the alternative many owners consider at this point, which is selling into a group that already has the surgical capacity.
What does an associate surgeon actually cost and return?
The cost is compensation, a surgical operatory with the instruments and sterilization capacity for implant surgery, a sedation plan, imaging and planning, malpractice, and a share of a treatment coordinator's time. The return is the contribution from every case the associate produces, less what the practice would have earned from the referred patient's restorative work anyway.
Compensation
Surgical associates are compensated on a percentage of production, a guaranteed base against production, or a salary. Percentage arrangements align the associate's income with volume and shift the risk of a slow start to the associate, which makes them harder to recruit. A base against production is the common compromise.
The operatory and equipment
A surgical operatory needs the instruments, the motor, the surgical kit for the practice's implant system, sterilization capacity, and often a cone-beam scanner. The CBCT and guided surgery guide prices the scanner; the rest is smaller but not trivial.
Sedation
Full-arch patients want it. The associate may hold an IV sedation permit, the practice may bring in a mobile anesthesiologist, or the practice may limit itself to oral sedation. The IV sedation certification guide covers the first option.
The return
The guide to the cost of a full-arch case gives the per-case contribution. Against the fixed costs above, a full-time associate needs a steady flow of arches and single implants to be worth more than the traveling-surgeon model, and the practice should model both before hiring.
What has to be in place before the associate starts?
Cases. A practice hires a surgeon and then discovers that the cases it referred out were the ones patients accepted from a specialist, and that generating full-arch consults for an unknown associate takes marketing the practice has not done. Before the start date the practice needs a treatment coordinator, a financing waterfall, a fee presentation, reviews that mention implants, and a plan for the first three months of consults.
The coordinator
The treatment coordinator role guide describes the job. An associate without a coordinator presents their own fees and follows up on their own consults, and the close rate shows it.
The marketing
The marketing fundamentals guide covers what has to exist before ads, and the guide to Google Ads for full-arch patients covers the campaign most practices run to fill a new surgeon's schedule. A directory listing with the associate's credentials puts them in front of patients already comparing providers in the city.
The referral relationships
Keep them. A practice that brings surgery in-house should still refer the cases outside its new associate's competence, and the specialists it has referred to for years are the ones who will take the zygomatic case or the medically complex patient. Burning those relationships to keep every case is a mistake that shows up in the first complication.
What mistakes turn a good hire into a bad year?
Hiring before the cases exist, compensating in a way that leaves the associate idle and resentful, skipping the coordinator, underbuilding the operatory, and letting the associate build a program the owner does not understand. The last is the subtle one: an owner who does not know how full-arch cases are planned, priced, and financed cannot manage a surgeon who does, and the program becomes the associate's rather than the practice's.
- Count referrals for three months before deciding anything.
- Model the traveling-surgeon and full-time models against that volume.
- Hire the coordinator and build the fee presentation and financing before the surgeon starts.
- Fund the first three months of marketing before the start date.
- Keep the referral relationships for the cases outside the associate's competence.
- Learn the full-arch economics well enough to manage the program.
When is continuing to refer the right answer?
When the volume is below a surgical day a month, when the owner has no interest in surgery and no budget for a hire, when the practice's specialists are excellent and return restorative work reliably, or when the practice is a year or two from selling. Referring is not failure. It is a choice to keep the practice focused, and a practice with strong referral relationships and a full restorative schedule is a good practice.
The Bottom Line
Stop referring implants out when the referred cases would fill a surgical day a month and the practice can keep generating that volume. Below that, keep referring. At that level, a traveling surgeon keeps the patient and the restorative work with no salary risk. Above several surgical days a month, a full-time associate returns more, provided the coordinator, the financing, the marketing, and the operatory exist before the start date. Keep the referral relationships for the cases the associate should not take, and learn the economics well enough to manage the program.
