An open contact crown is one of the most frustrating causes of remakes and patient complaints. While it can't always be prevented entirely, many open contacts happen because of small breakdowns somewhere along the way, in treatment planning, impression taking, communication, or seating. These practical tips can help reduce the risk of open contacts in dental crowns and improve the predictability of your crown and bridge cases.
Many contact issues can begin with inaccuracies in the impression or digital scan. A few things to watch for:
Even small inaccuracies here can translate directly into a contact that's too tight, too loose, or missing altogether once the restoration is seated. If you want a deeper look at where things commonly go wrong, our guide to common impression errors and our full breakdown of dental impressions both walk through the details step by step.
Lab communication is one of the easiest things to get right, and one of the most commonly overlooked. Make sure every case includes:
At PRO-Craft, dentists have direct access to experienced technicians who can review case details and help resolve questions before fabrication. That communication is especially valuable when a case involves unusual contacts, multiple units, implants, or other restorative complexities.
The more your lab knows about the specific mouth they're building for, the less guesswork goes into designing the contact and the less likely you are to see it come back off.
Teeth can shift between preparation and final seating, particularly if the provisional restoration does not adequately maintain proximal contacts. A few factors to keep in mind:
A temporary that's loose or does not maintain proper proximal contact can allow neighboring teeth to shift, potentially changing the space available for the final restoration.
Before you cement anything, take the extra minute to confirm the contact is right. This is where a crown with open contact often gets caught or missed. Steps worth building into your routine:
Catching an issue before cementation is far easier than addressing it afterward, when correction may require significantly more chair time or, in some cases, a remake.
Some cases carry more risk than others, and it's worth slowing down a little more when you're working with:
Implant cases deserve particular attention. Unlike natural teeth, osseointegrated implants do not undergo the same physiologic tooth movement. Changes in the position of adjacent natural teeth over time can therefore contribute to proximal contact loss next to an implant-supported crown. Accurate records and careful contact design at delivery are especially important in these cases.
When it comes to more involved cases, PRO-Craft Dental Lab also provides case-planning support so restorative details and potential challenges can be addressed before fabrication begins.
For more on managing these more involved cases, our guide to improving full-mouth dental restoration is a good place to start, and the team at our crown and bridge dental lab can walk through complex cases with you directly.
Even a strong clinical workflow depends on accurate fabrication and communication with your dental laboratory. PRO-Craft combines technician support, case planning, and a multi-step quality assurance process to help identify potential problems before a restoration reaches your practice.
Working with PRO-Craft Dental Laboratory gives your practice access to:

Preventing an open contact crown comes down to attention to detail throughout the entire restorative process, from accurate impressions and thorough communication to careful verification before seating. None of these steps are complicated on their own, but skipping even one can undo everything that came before it. Working with an experienced dental laboratory that catches issues early can help minimize adjustments, reduce remakes, and improve outcomes for both you and your patients.
