Screw retained implant

The use of implant -supported single crowns has become a well-established and preferred approach to compensate missing single teeth. This will ultimately result in implant failure. When deciding between screw retained and cement retained implants, there are benefits and different techniques to using each metho often related to location and position of the implant.


The choice of method is usually based on the clinician’s preference and the position of the implant. The main advantage of the screw - retained crown is retrievability. The crown is not only recoverable, but no damage occurs upon removal of the crown.

Screw-retained Implant. In the event of loosening or fracture, the crown can easily be removed. Cleaning, screw replacement and assessment of surrounding tissue is also possible. Cementing implant retained full crowns is consistent with routine fixed dental prosthesis fabrication.


Cements for natural teeth may not be ideal for dental implants. Excess cement retention may lead to late implant failure. A fixed dental prosthesis can be secured to an endosseous implant via cementation (using a provisional or definitive cement) on an implant abutment that is screw retained to the implant or directly in the implant via screw retention.


The clinical decision as to which retention system best suits the individual patient depends on several factors.

The biggest obstacle from patients is esthetics. They feel like if they are going to pay so much to replace missing teeth, they better darn well look like a real tooth and not a tooth that just had a root canal through a crown. Professional training and continuing development in implant dentistry – for all areas of implant dentistry, on all skill levels. The advantages are the restoration can be unscrewed and repaire maintenance, cleaning and alterations can be done without damaging the substructure, restoration or implants. The resultant bone limitations in the anterior frequently call for implant angulation that must be corrected with a custom abutment.

These codes should not have the same definition. A few codes remain from the previous ADA CDT-2. The ideal planning objective for a zirconia screw - retained bridge is to project the access holes into the cingulum area of the anterior region or into the mid-occlusal lingual aspect of the posterior teeth.


Otherwise, angling the screw access hole toward the facial aspect of the anterior teeth causes esthetic problems. Often a loose screw can be a bit nerve racking for us dentists. To find out for sure we may need to drill through the crown and access the screw hole. If the implant is loose, it’s obviously a much bigger problem.

Esthetics tend to be the biggest obstacle, especially in anterior cases. In my own practice I have been increasing the number of screw-retained implant restorations for a variety of reasons but the main two are retrievability and eliminating the need for cement. This overview concludes that the choice of retention type ( screw retained or cement retained ) might not influence the overall survival of the implant-supported fixed dental prosthesis , but may be.

Its design is based on the latest technology and scientific know-how in implant dentistry. When you have lost your natural teeth, a variety of complications can arise that impact your physical and emotional health – beyond just your smile. The method employed to fill the screw access channel of implant abutmentscan have an effect on the retention of coronal restorations cemented with TempBond.
