Precision of Fit

Maximize success by using only Authentic Components

The accepted requirements for achieving long-term maintenance and performance of implant treatments include:

  • properly matched implant system components
  • precise fit and connection between the abutment and implant
  • appropriate abutment screw preload

Expert insights

6:25 thru 9:18. Importance of properly matched/fitting components. Clinical example. Take-home message: Make sure that the prosthetic parts used are those of the [implant] manufacturer.
32:58 thru 35:40 & 49:12 thru end. Experience and examples of the problems that can present due to the use of 3rd party components.
15:35 thru 30:05. Implant and prosthetic components function together as a system and therefore impeccably fitting components are key for long-term success. Dr. Holst explains how small variations within the various components can add up to substantial loads and overloads of the system, risking component malfunction or fracture. He concludes that it is important to consider the system performance, not just individual components and that the implant-to-abutment interface quality determines the long-term performance of the system.
The advantages of CAD/CAM technology compared to cast procedures. Highlights CAD/CAM technology providing consistent and exceptional precision of fit, predictable results, significant time savings both in the laboratory and in the clinic, biocompatibility of typical CAD/CAM materials such as Titanium and Zirconia and reduced cost. CAD/CAM solutions can be used in fixed solutions with Titanium plus acrylic or ceramic veneered Zirconia, and fixed-removable solutions with a milled overdenture bar.
BARS and PIB. 15:31 thru end. Zirconia and titanium CAD/CAM frameworks have consistently higher accuracy with tested scanners. Cast frameworks are significantly less accurate. How does veneering and firing affect fit? Also, greater accuracy in the laboratory requires greater accuracy in clinics.
The Importance of Using Authentic Components on top of dental implants. What are the requirements for long term satisfactory performance of your implant restorations. Review properly matched components, precise fit and the proper preload on the screws. Look at the CC connection, tightness and quality of the fit. How do poorly fitting components affect the case.
