Repair vs. Replace: The Dental Equipment Decision Framework

The Question That Costs Practices Thousands — Answered Wrong The service tech just told you the repair is $2,200. The chair is 9 years old. Should you fix it or replace it? Most practice owners answer this question by feel. Below is the actual framework — so the answer is a calculation, not a guess. And at the bottom of this post: a free interactive calculator that runs the analysis for you in under 3 minutes. The Core Framework The repair-vs-replace decision comes down to four variables: Current Fair Market Value — what would this equipment sell for today? Repair cost — what does this specific repair cost? Remaining useful life — how much service life is left after the repair? Replacement cost — what would a suitable replacement cost, new or refurbished? The rule of thumb most equipment managers use: if repair cost exceeds 40% of current FMV, replace. If repair cost is under 20% of FMV and the equipment has significant remaining useful life, repair. To establish FMV for any piece of dental equipment, run it through DentalAssetIQ — the platform tracks real secondary market transactions for 3,500+ models across 230+ manufacturers.

For oil-free units: replace if the unit is over 10 years old or if repair exceeds 35% of FMV. See Dental Air Compressor Value on DentalAssetIQ for current market data. Panoramic X-Rays Detector failure is the primary repair scenario. A detector replacement at $4,000–$12,000 on a unit over 8 years old is usually a replace decision. See Dental Panoramic X-Ray Value for the full framework. Sterilizers Sterilizers hold value better than almost any other equipment category. A Midmark M9 UltraClave repair at under 40% of FMV is almost always worth doing. See Dental Sterilizer Value for secondary market data. Dental Chairs Hydraulic chairs can be repaired well into their second decade if the core platform is sound. Electromechanical chairs have shorter effective service lives (7–10 years).

Equipment you repair and maintain holds more value in a transaction than equipment at the edge of replacement. See What DSOs Actually Pay for Equipment at Acquisition for the buyer's perspective.
