Single-Unit Crown Workflow - Opportunities to Optimise Efficiency in Dental Practice

Optimising patient care and efficiency for the dental office has never been more important. Here, we’ll discuss current workflow challenges in the fabrication and delivery of single-unit crowns, common areas of inefficiency and the financial implications. We’ll also look at ways to address these challenges, create more positive experiences and grow your practice.  

Reasons for structural failures include:

• Using a crown material with insufficient strength for the clinical situation
• Insufficient clearance created while preparing the tooth or, when further occlusal reduction is not possible, failing to use a material that could be milled with a reduced wall thickness
• Selecting the incorrect cement or technique for the case (e.g., failure to use an adhesive technique or to condition the inner surface (intaglio) of CAD/CAM block materials). 

Common areas of inefficiency in the Single-Unit Crown Workflow

Common sources of inefficiency in the single-unit crown workflow include impression taking and the delivery of provisional restorations.

The number one source of inefficiency is excess trimming and adjusting of the final crown, which an accurate final impression and well-fitting provisional can help to avoid.¹ Accurate impressions require good soft tissue management, yet poor haemostasis is a problem that more than half of dentists report² and obtaining adequate haemostasis is regarded as the #1 challenge in final impression procedures.^1,5 In examining more than 1100 impressions from 3 large and 1 small dental laboratories, evaluators detected errors in 86% of them – more than half were critical errors affecting the finish line, such as impression voids, preparation margins obscured by soft tissue, or blood over the finish lines.⁵  

Final impressions are not the only contributor to inefficiency in the single-unit crown workflow. Let’s now explore the efficiency challenges for provisionals:

• 1 in 3 offices report spending ‘too much time’ fabricating provisionals¹
• 97% of clinicians say they ‘often’ need to repair or replace provisionals¹
  • 75% of issues were attributed to the preliminary impression
  • Other causes include selecting the wrong tray or using a weak provisional material.  

Dentsply Sirona Single-Unit Crown Workflow Solution

Here at Dentsply Sirona, we want to support you with a single-unit crown workflow solution that will improve efficiency each step of the way. 

Our Final Impression Solution includes Dentsply Sirona’s Aquasil^® Ultra+ Smart Wetting Impression Material formulated to help you optimise the accuracy of your conventional final impressions. This VPS material offers leading intraoral performance for both hydrophilicity and tear strength, adding an extra layer of confidence in challenging intraoral environments. Alternatively, digital impressions are fast, accurate and improve communication with the patient and the lab with Dentsply Sirona’s intraoral scanner CEREC Primescan^®.

Our Provisional Solution includes Dentsply Sirona’s Algin-X^™ Ultra, an alginate alternative that delivers predictable accuracy with dimensional stability. Our Integrity^® Multi•Cure Temporary Crown & Bridge Material delivers strength where and when you need it, with on-demand light curing to allow for immediate and precise trimming. It also finishes smoothly to help maintain tissue health. Cementation of the provisional is simplified with Dentsply Sirona’s Integrity^® TempGrip^® Temporary Crown & Bridge Cement which is moisture tolerant, and provides for sufficient retention of the provisional yet stays in the provisional during removal, making clean-up easy. 

Our CAD/CAM Restorative solution includes CEREC MTL^® Zirconia, a multi-transitional layer zirconia that offers high strength (>850 MPa) and excellent aesthetics. CEREC Tessera^™ is also available, an advanced lithium disilicate that also offers excellent strength and aesthetics for CAD/CAM restorations, whether in the laboratory or chairside. The Chairside Solution with CEREC Primemill^® and CEREC SpeedFire^® is designed for speed, accuracy and convenience, enabling the practice team to create and fit a restoration in just one patient visit.

Lastly, Dentsply Sirona’s Crown Cementation Solution offers efficient, and reliable cementation with easy clean-up. Calibra^® Ceram is an adhesive resin cement formulated for maximum strength, making it ideal for glass ceramics like CEREC Tessera^™ blocks. Simplified, reliable cementation is designed in, and when used with Dentsply Sirona’s Prime&Bond active^® adhesive, no primer is needed, and excellent strength is obtained. Dentsply Sirona’s Calibra^® Universal cement is ideal for zirconia like CEREC MTL^™ Zirconia blocks. This cement combines aesthetic shading with a self-etching adhesive. It is the simple choice for successful results and no need for additional etchant or adhesive.
