How to Avoid Open Contacts in Dental Crown and Bridge Cases

Written by Greg Schubert | September 24, 2026

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.

Capture Accurate Impressions or Digital Scans Every Time

Many contact issues can begin with inaccuracies in the impression or digital scan. A few things to watch for:

  • Complete margin capture, with no voids or drags near the proximal areas
  • Clear proximal anatomy so your lab can accurately reproduce contact points
  • Proper tissue management to avoid distortion around the prep
  • Avoiding scan errors or impression material issues that can affect the accuracy of the final model

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.

Give Your Laboratory Complete Case Information

Lab communication is one of the easiest things to get right, and one of the most commonly overlooked. Make sure every case includes:

  • A detailed prescription with clear restoration requests
  • Clinical photos, especially for anterior or high-visibility cases
  • Accurate bite records
  • Material selection
  • Notes on adjacent tooth considerations, such as recent restorations or existing contacts

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.

Minimize Tooth Movement Before Seating the Restoration

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:

  • Well-fitting temporaries that maintain space and prevent adjacent teeth from drifting
  • Realistic scheduling that doesn't leave too much time between prep and final seating
  • Understanding why delayed seating appointments increase the risk of an open contact between crowns

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.

Verify Proximal Contacts Before Final Cementation

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:

  • Floss testing at every proximal surface, not just the obvious ones
  • Visual inspection under good lighting and, when possible, magnification
  • Making contact adjustments before cementation rather than after
  • Confirming contacts on both sides of the restoration, not just the side facing the prep

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.

Take Extra Care With Complex Crown and Bridge Cases

Some cases carry more risk than others, and it's worth slowing down a little more when you're working with:

  • Multiple adjacent crowns in the same quadrant
  • Bridges spanning several units
  • Full-mouth rehabilitations
  • Implant-supported restorations

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.

The Answer to Crown Contact Issues? Work With a Dental Lab That Prioritizes Precision

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:

  • A 10-step quality assurance process for every case
  • Direct access to experienced dental technicians for technical support
  • Collaborative case planning for complex restorations
  • Digital and traditional workflows to accommodate your preferred case-submission process
  • Crown and bridge restorations fabricated in PRO-Craft's U.S.-based laboratory

Achieve Fewer Open Contacts: Start With a Stronger Process

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.
