Implant Crown and Bridge

 

At ROE, we offer three distinct implant crown retention methods to address diverse clinical scenarios and patient requirements.

Cement-Retained Crowns
Cement-retained crowns provide superior aesthetics with seamless appearance by eliminating visible access holes, making them ideal for high-aesthetic anterior cases, though they require meticulous cement cleanup and present challenges for future retrievability.

Screw-Retained Crowns
Our screw-retained crowns represent our most popular posterior solution, featuring full-contour zirconia construction with precision titanium base interfaces that provide exceptional retrievability while eliminating cement-related complications at the implant margin, delivered in just five working days with model-free digital workflows.

Screwmentable Crowns
For cases requiring the advantages of both approaches, our innovative screwmentable crowns combine a custom-milled titanium abutment with a crown fabricated as separate components, allowing the abutment to be seated first for perfect fit verification, followed by independent crown adjustment for optimal contacts and occlusion before extraoral cementation and final screw retention—delivering the best of both worlds with screw retrievability and cement-like seating precision.

Cement-Retained Crown Overview

Clinical Benefits per
Implant Retention Technique

 

Cement-Retained

  • Superior Esthetics – No visible access holes create a seamless appearance that closely mimics natural tooth structure, ideal for high-smile-line patients
  • Optimal for Anterior Applications – Maximum esthetic results in high-aesthetic zones where screw access holes would create unacceptable cosmetic compromise
  • Accommodates Implant Angulation – Provides flexibility when implant positioning would place screw access hole on facial surface, allowing correction through abutment design
  • Familiar Clinical Workflow – Similar to traditional crown cementation on natural teeth, requiring no new techniques or specialized delivery protocols
  • Enhanced Porcelain Integrity – Higher resistance to porcelain fracture compared to screw-retained alternatives due to uninterrupted crown structure

Screw-Retained 

  • Complete Retrievability – Easy removal for maintenance, repairs, or component replacement without damaging restoration, providing long-term treatment flexibility
  • Eliminates Cement Complications – No cement washout, excess cement retention, or peri-implant tissue irritation that can lead to peri-implantitis and implant failure
  • Rapid Turnaround – Five working day delivery with streamlined digital workflows enables predictable treatment scheduling and efficient case completion
  • Enhanced Hygiene Access – Removable design allows thorough cleaning of implant components and surrounding tissues, supporting long-term implant health
  • Simplified Delivery Protocol – Straightforward seating procedure reduces chair time and clinical complexity compared to cement cleanup requirements

Screwmentable

  • Hybrid Seating Advantages – Two-stage process allows abutment verification first, then independent crown adjustment for optimal contacts and occlusion, like traditional crown and bridge procedures
  • Eliminates Intraoral Cement – Extraoral cementation removes cement from the oral environment while maintaining a precise crown-to-abutment connection
  • Superior Retrievability – Maintains screw-retained benefits for easy removal and maintenance while achieving cement-like precision in seating
  • Optimal Fit Verification – Abutment can be seated and confirmed for perfect implant connection before crown placement, ensuring passive fit and positive seating
  • Enhanced Clinical Control – Allows fine-tuning of contacts and occlusion with the same ease as cement-retained crowns while avoiding cement cleanup challenges

Implant Retention Decision Guide

Cement-Retained vs
Screw-Retained vs Screwmentable

Overview
The choice between screw-retained and cement-retained restorations depends on specific clinical factors, including implant positioning, available restorative space, aesthetic demands, and retrievability considerations. Both retention methods have similar complication rates of 3-5%, but each has distinct advantages for different clinical scenarios.

When to Use Cement-Retained Implants
Choose cement-retained restorations when working in high-aesthetic anterior cases where implant angulation would place the screw access hole on the facial surface, creating cosmetic compromise, or when maximum esthetic demands require seamless appearance. Cement-retained cases require careful cement cleanup to prevent bacterial colonization and tissue inflammation that can jeopardize implant success.

When to Use Screw-Retained Implants
Select screw-retained restorations when implant positioning allows the access channel to exit through the cingulum anteriorly or central groove posteriorly, when restorative space is limited (requiring less space than cement-retained options), or when retrievability is important for future maintenance and repairs. Screw-retained options are advantageous in posterior applications and eliminate the risk of residual cement complications that can lead to peri-implantitis and implant failure.

When to Use Screwmentable Crowns
Choose screwmentable crowns when you need precise seating control and occlusal adjustment capabilities of cement-retained restorations while maintaining the retrievability and hygiene benefits of screw retention. This hybrid approach is ideal for complex bite relationships, challenging implant angulation, or when you need to verify perfect abutment fit before crown placement, all while avoiding intraoral cement complications and their associated risks.

Conclusion
Successful implant restoration depends on careful case evaluation and selecting the retention method that best serves both immediate clinical needs and long-term patient outcomes. Consider the specific factors of each case when making retention method decisions.
