Dentsply Sirona · Dental Equipment · $30,000 – $55,000
A unit with <8,000 milling hours and current service contract runs $48k–$55k; <12,000 hours with a 1-year service gap drops to $32k–$38k. Every 2,000 milling hours past 10,000 costs you $3k–$5k in immediate parts replacement.
Pull the milling spindle cover and look for ceramic dust caking on the spindle bearing - that's $4,200 to replace. Check the optical window for etching or haze under LED backlight; replacement is $2,800 and affects scan accuracy. Run a test scan on their demo block and watch for milling chatter or grinding noise.
California and Texas are saturated with MC XL units because Aspen Dental and Pacific Dental Services rolled them out aggressively 2016–2019; expect $4k–$8k discounts in those regions. Florida and Arizona are tight - clinics buying now, not selling.

No. Dentsply mills are proprietary and locked to the unit via firmware. Generic blocks work but scans reject them 30–40% of the time. Buy OEM blocks; they cost $18–$24 each, not much more than knockoffs.
Dentsply wants $3,600–$4,200 per year for parts and labor coverage. Heartland Dental clinics self-insure and budget $2,200 in parts annually; if you hit spindle failure without coverage, you're at $8,500 downtime plus $4,200 parts. Math says buy the contract if you mill >400 units/year.
Milling handpiece: 4,000–6,000 hours before bearing play becomes visible. Rebuilds run $1,900–$2,400 through Dentsply service; aftermarket rebuilds are $1,100–$1,400 but void the machine's service history and clinics hate that when they resell. Not worth the $700 savings.

I can source OEM parts at 18–22% below list because I work direct with Dentsply distributor accounts; saves you $2,400–$3,100 annually on the usual replacements. I also have a 2-unit network in Irvine that tests machines before sale, so you skip the $1,500 remote diagnostic calls.
