Same-Day Crowns: Are They as Good as Lab Crowns?

A traditional crown takes two appointments spread over two to three weeks: prep and impressions on the first visit, a temporary crown to wear in between, and the final placement on the second. Same-day crowns collapse that into a single appointment — the tooth is scanned, the crown is milled in-office, and it is bonded the same day. The most common question dentists and patients ask before switching is simple: are same-day crowns as durable as lab crowns? The short answer, supported by long-term clinical research, is yes — in the right cases.

How do same-day crowns work?

Same-day crowns are produced chairside with a CEREC® system using a three-step digital workflow:

• Scan — an intraoral camera captures a 3D digital impression of the prepared tooth, replacing the conventional impression tray.
• Design — CAD software designs the restoration to match the patient's anatomy, shade, and bite.
• Mill — an in-office milling unit fabricates the crown from a ceramic block, ready to bond in the same session.

The entire process typically fits inside a single extended appointment, eliminating the temporary crown phase entirely.

Do same-day crowns last as long as lab crowns?

This is where the clinical evidence matters most. A 7-year study of 447 chairside CAD/CAM all-ceramic restorations reported a success rate of 98.66%, with only six failures across the whole group (prospective chairside ceramic crown research). A separate 15-year follow-up of chairside-fabricated monolithic lithium disilicate crowns found restorations still in clinical service more than a decade after placement (15-year survival study).

In other words, when indicated correctly, modern same-day ceramic crowns deliver longevity comparable to conventional lab crowns — the deciding factors are tooth preparation, occlusion, and oral hygiene, not whether the crown was milled in-office or at a lab.

Same-day crowns vs. traditional lab crowns

The clearest advantages of the single-visit workflow are time and patient comfort. In a clinical comparison of single-unit crowns, intraoral scanning took roughly 7.5 minutes versus about 12.7 minutes for conventional impressions, and the marginal and internal fit of the chairside crowns was statistically comparable to lab crowns (time-efficiency and fit-accuracy study).

The practical differences:

• Appointments: one extended visit vs. two visits over 2–3 weeks.
• Temporary crown: none vs. a provisional that can loosen or fracture.
• Impressions: digital scan vs. physical impression tray.
• Materials: ceramic blocks (e.g. lithium disilicate) vs. the full range of lab materials.
• Fit and longevity: clinically comparable for appropriate single-unit cases.

What same-day crowns mean for a practice

For a dental practice, every crown completed in-house is a crown that does not leave as a lab fee, and a patient who does not occupy a second appointment slot. Over a year, in-office milling recovers chair time, retains revenue that would otherwise go to the lab, and gives the practice a genuine differentiator: finished restorations in one visit. The historical barrier has been the cost of the equipment — which is exactly where certified pre-owned systems change the math.

CAD/CAM Center Miami offers certified pre-owned CEREC® systems from $39,900 — roughly half the price of new equipment — each backed by a 1-year bumper-to-bumper warranty, with white-glove installation & training available and CAD/CAM Care® available as an ongoing annual service plan. We have placed 300+ systems and served 800+ dentists.

Frequently asked questions

How long do same-day crowns last?

Clinical studies report high survival for chairside ceramic crowns over 7 to 15 years, comparable to lab-made crowns when the case is appropriate and oral hygiene is maintained.

Are same-day crowns as strong as lab crowns?

For single-unit restorations in suitable clinical situations, same-day ceramic crowns show comparable marginal fit and survival to conventional lab crowns in published research.

How long does a same-day crown appointment take?

The full scan-design-mill-bond workflow typically fits into a single extended appointment, removing the need for a second visit and a temporary crown.

What equipment makes same-day crowns possible?

A chairside CAD/CAM system such as CEREC® — combining an intraoral scanner, design software, and an in-office milling unit. Certified pre-owned systems make this technology accessible at roughly half the cost of new.
