How to resolve fitting issues with zirconia crowns

The past ten years have seen an upsurge in using zirconia crowns. Because zirconia restorations offer robustness and realistic aesthetics, patients today prefer them to metal-based crowns. Furthermore, zirconia is strong and can survive repeated vigorous chewing and grinding. Are you looking for any labs that used the “dental crown labs near me” box? The “Managed Lab Services” solution from Cayster allows consumers more control, lowers error rates, and produces data to aid in decision-making. Expanding and PE-backed practice groups were able to Measure Outcomes while giving their practitioners Cognitive Autonomy thanks to Cayster’s enterprise, which offers dental labs NYC.

Zirconia restorations could last a patient their entire lifetime if kept up to date. Some dentists choose to refrain from utilizing zirconia crowns or developing the skills necessary to place them in their patients’ mouths because of the material’s recent development. This inexperience might occasionally result in crowns that need to fit correctly.

You should consider problems with the fit of your dental crown. You must understand how to place a crown properly and how to alter the suitability of the crown should issues emerge, considering zirconia crowns are made to help seal and safeguard your patient’s teeth from additional harm. For the patient’s safety, any problems with dental crowns should be fixed immediately.

Why might zirconia crowns not fit properly?

  • The dental crown had been made in a hurry. Crowns that are hurried can have inappropriate margins. The infiltration or leakages of saliva, as well as bacteria, into crowns that have open margins in the cement, can cause decay and periodontal problems.
  • The crown needed to be properly anchored. To prevent mistakes throughout cementation, including a hole in the crown, clinicians must carefully inspect the crown margins. Saliva and germs can enter the crown through this gap, causing tooth damage and infection.
  • It needed to be clarified what the impression was. The imprint quality will be impacted by air pockets, drag and pull marks, incomplete impression data, incorrect marginal impressions, and subpar impression material.
  • Preparation irregularities.

How to resolve issues with debonding

  • Try changing your cementation procedure if your zirconia crowns start debonding. Before polishing the tooth with pumice, most clinicians check the zirconia crown’s fit in the patient’s mouth.
  • If the zirconia crown doesn’t really come with a built-in primer, proceed by cleaning the intaglio area of the restoration before priming or adhering it.
  • The crown should then be cemented, the cure tacked, and any extra cement scraped off.

Despite these being all standard practices, therapists occasionally need to fully clean the intaglio surface, which leads to bonding failure. The phosphate groups must be carefully removed for the zirconium oxide sites to successfully bond in the patient’s mouth since they form a link with zirconium oxide.

Three strategies for eliminating phosphate groups

  1. Sandblasting. Most manufacturers advise lightly sandblasting the inside surface at low pressure, even if it’s occasionally recommended to use something other than aluminum oxide with a 50-micron diameter. Always read the manufacturer’s instructions before using this technique.
  2. Hypochlorite of sodium. The intaglio of either crown is cleaned using cotton soaked in sodium hypochlorite and full hydrogen peroxide at a 5% concentration. The cleaning solution is then removed, and the repair is allowed to air dry.
  3. Ivoclean. Use a specialized solution, such as Ivoclean. Before rinsing, let the solution sit on the crown for 20 seconds. After air drying, the crown is prepared for bonding.

Preventing facial-lingual lingual rocking in restorations

Do you think zirconia crowns rock facial-lingually, but the margins fit perfectly? Zirconia crowns for patients must be checked more carefully, and it takes longer to correct this issue than you might imagine.

Any imperfections are erased when the digital picture of the patient’s tooth is created since milled restorations possess smooth internal surfaces and cannot fit over them or undercuts. On conventional versions, a die-spacer is typically employed, which leaves a gap of about 50–100 microns. Have your clinician check that the computer program when creating zirconia restorations is set to provide well-fitting margins while defining the amount of space between the fit surface and the prep site. This easy procedure will keep zirconia crowns from swaying facial-lingually and serves as a functional equivalent of a traditional die-spacer.
