Hocera Dental Solutions
Modern digital dentistry has brought new vitality to restorative dentistry worldwide. However, even with advanced CAD/CAM systems and digital workflows, some key clinical procedures still rely heavily on the precision and expertise of dentists and dental technicians. At Hocera, we understand that the success of crowns and bridges depends on both high-quality materials and careful clinical protocols. Below is a practical guide for crown and bridge try-in, common issues, and troubleshooting tips for dental professionals.
🦷 1. Pre-Try-In: Check the Prosthesis on the Model
Before placing the crown or bridge in the patient’s mouth, always examine the restoration on the working model. Key aspects to check include:
- Marginal fit and seal
- Contact points
- Occlusion accuracy
- Overall aesthetics
Common Issues and Solutions:
1️⃣ Tight Proximal Contacts
Often caused by inaccuracies in the die or wear at the cervical contact points.
✔️ Solution: Use articulating paper to identify tight spots, then carefully adjust and polish.
2️⃣ Small Nodules or Bubbles on the Tissue Surface
Usually appear due to air bubbles during the casting process.
✔️ Solution: Gently remove nodules using a small round bur.
3️⃣ Over-extended Margins
May result from poor impressions, excess wax, or untrimmed porcelain.
✔️ Solution: Adjust the external axial surface; if necessary, send it back to the lab for remaking.
4️⃣ Insufficient Margins
Often caused by unclear impression details or poor trimming of the die.
✔️ Solution: Take a new impression and remake the prosthesis.
5️⃣ Damaged Die
Caused by mishandling or air bubbles that wear down the margin area.
✔️ Solution: If minor, correct carefully; if seating remains impossible, return for lab remanufacture.
🦷 2. Try-In and Intraoral Adjustments
Once the model check is complete, remove any temporary crown or bridge and clean residual cement thoroughly, especially around the sulcus area.
Recommended Clinical Try-In Steps (Hocera Best Practices):
✅ Step 1: Ensure no residual cement or soft tissue interference remains.
✅ Step 2: Re-check tight contacts and adjust if needed. Inspect the working model for damage in the contact area.
✅ Step 3: Identify any production-related defects, such as bubbles, nodules, or margin irregularities; remove carefully using a bur.
✅ Step 4: If margins are over-extended, adjust only the outer surface — never reduce the inner surface to maintain a precise fit.
✅ Step 5: If the restoration does not seat fully, gently grind minimal areas, re-try, and repeat until fully seated.
🔍 Tip: Combine High-Quality Materials with Precise Protocols
At Hocera, we believe that using premium zirconia blocks and advanced multi-layer CAD/CAM solutions significantly reduces chairside adjustments and remakes. To achieve optimal results:
✔️ Use accurate intraoral scanning for precise digital models
✔️ Maintain open communication with your dental lab
✔️ Provide clear feedback on marginal fit and occlusion to refine workflows
By combining reliable digital workflows with well-trained clinical skills, you can deliver highly aesthetic, durable restorations that meet your patients’ expectations — every time.
