Every remake is quietly draining a chair hour off your P&L

<p>You are a general dentist or a small-DSO operations lead running the math after a bad month, and the number that keeps surfacing is remakes. Not the lab invoice (that part is visible), but the second appointment you cannot bill, the assistant time you already paid for, the patient who left the first visit with a temp and a slightly smaller reservoir of trust. The reason this query exists at all is that no one on the generic small-business finance SERP will do the dental-specific napkin math for you. Reddit threads, business school essays, and LinkedIn opinion posts show up for the words "cost" and "profit," but none of them price a single crown remake.</p><p>Here is what a single-unit posterior crown remake actually costs a restorative practice. Lab fee on the second unit (even if credited later, the cash cycle still hurts): roughly $110 to $180. Chair time on the reseat plus adjustment appointment: 45 to 60 minutes at a fully-loaded chair-hour cost most practices calculate between $400 and $650. Assistant and front-desk time to reschedule, sterilize, seat, and re-scan: another $60 to $110. Materials on the second try (impression material or scan time, temp cement, anesthetic if needed): $25 to $50. Patient-trust erosion: not on the invoice, but the reason single-unit remakes correlate with lower five-year retention in practices that track it. A single posterior remake lands somewhere between $595 and $990 of real cost against a crown you already billed at production.</p><p>Now multiply. A restorative practice delivering 60 units per month at an industry-typical 4 to 5 percent single-unit remake rate is absorbing roughly 2.4 to 3 remakes per month, or $1,400 to $2,970 of true cost that never shows up as a line item. A 12-office DSO at the same rate is absorbing $17,000 to $35,000 per month across the group. That is not a lab problem. That is a P&L problem your current lab is externalizing onto your schedule.</p><p>Prosthodontists reading this: the anterior aesthetic case remake is worse. Chair-time cost doubles because the try-in appointment matters. Shade-driven remakes on anterior cases run 8 to 12 percent at labs without a calibrated photography protocol, which is most of them.</p>

<p>Remakes are almost never a single-point failure. They are the compounding output of a lab process that has no design verification step before milling. The typical workflow at a high-volume commodity lab: your scan or impression arrives, a CAD technician you have never spoken to interprets the margin and the contact geometry, the design goes straight to the mill, sintering and finishing happen on schedule, the unit ships. If any one of those handoffs misreads the case (a slightly ambiguous margin, an unclear shade note, an occlusal record the CAD tech guessed at), the remake is baked in before the case ever left the lab. You just do not find out until delivery day.</p><p>The second root cause is the anonymous CAD pipeline. When you cannot name the technician who designed your crown, you cannot call that technician when the contact is open or the occlusion is high. The lab rep takes a message, routes it to a queue, and the root-cause conversation never happens. So the same failure repeats on the next case. Labs with a 6 to 8 percent single-unit remake rate almost always have this structure. Labs at 2 to 3 percent almost always do not.</p><p>The third cause is the cheap-unit-price trap. Lab A at $89 per unit with a 7 percent remake rate delivers a true cost per delivered restoration of roughly $89 plus 7 percent of a $600 to $900 remake burden, which lands the real per-unit cost at $131 to $152. Lab B at $129 per unit with a 2 percent remake rate lands at $141 to $147. The "cheap" lab is not cheaper. It is just moving the cost off its invoice and onto your schedule.</p>

<p>Dani Dental runs a design-verification-before-milling process on every case. Before your scan gets sent to the mill, the technician assigned to your case (named, direct phone line, on the traveler with the case) reviews the margin, the contact geometry, the occlusal clearance, and the shade documentation against the prescription. If anything is ambiguous, you get a call before the puck is cut, not after the crown is delivered. That single step is the largest driver of the sub-2.5 percent target remake rate Dani tracks and reports back to clients quarterly.</p><p>The second differentiator is in-house milling. Cases do not leave the Tempe facility for the milling step, which removes an entire category of fit-tolerance variance that outsourced-milling labs cannot control. Combined with three generations of Dobrikov bench experience (Sofia 1988, Arizona 1993, and the current lab floor), the finishing and sintering variables that produce delivery-day adjustments are calibrated case by case, not batched. And every case ships with a remake warranty in writing: free remake, expedited turnaround on the second attempt, and a root-cause report so the failure does not repeat on your next case.</p><p>For a 10-to-30-office DSO, Dani will build a remake-spend model from your last quarter of invoices and quantify the consolidation dividend before you sign anything. That is the audit, not a pitch: real numbers, your data, your P&L.</p>
