Overview: This guide outlines the various implant abutment types offered by Dandy and details the clinical processes for screw-retained, cement-retained, and screwmentable restorations.
Prerequisites
Before selecting an abutment or retention method, ensure you have identified the specific implant system and platform size used for the patient.
Implant Abutment Types
Dandy offers patient-specific and stock components to support various clinical needs and aesthetic requirements.
Custom Titanium Abutments
Custom titanium abutments are milled specifically for individual patients. These abutments allow clinicians to control marginal depth, angulation, parallelism, and tissue contour. Titanium is the most durable material and provides excellent support for the crown. Approximately 92% of Dandy implant cases utilize custom titanium abutments. Clinicians can use these abutments for screw-retained, cementable, and screwmentable restorations.
Custom Zirconia Hybrid Abutments
A custom zirconia hybrid abutment consists of a zirconia component with a titanium interface. Like the full titanium version, the custom design allows for precise control over marginal depth, angulation, and tissue contour. These abutments are the preferred choice for aesthetic areas because the zirconia eliminates the gray or gold tones often visible with standard titanium. Clinicians can use these abutments for screw-retained, cementable, and screwmentable restorations.
Titanium Base Components
A Titanium Base (Ti-Base) is a stock titanium component. The Ti-Base creates the necessary interface between the dental crown and the implant.
Restoration Retention Methods
Retention methods determine how the restoration is secured to the implant or abutment and how easily the clinician can remove it if necessary.
Screw-Retained Restorations
A screw-retained restoration is a one-piece unit adhered in the laboratory. Dandy custom-designs each restoration to create an ideal emergence profile.
Retrievability: The restoration features an access hole, allowing the clinician to remove the restoration easily.
Benefits: These restorations provide high aesthetics and durability without the need for cementation in the clinical setting.
Cement-Retained Restorations
In a cement-retained restoration, the crown and the abutment are delivered as separate components.
Clinical Process: The clinician cements the crown directly onto the abutment inside the patient’s mouth.
Visual Profile: The crown does not have an access hole, which provides a solid, continuous occlusal surface.
Retrievability: Clinicians do not consider cement-retained restorations to be retrievable.
Screwmentable Restorations
Screwmentable restorations combine the features of both cement and screw retention.
Clinical Process: The abutment and crown are delivered separately. The clinician cements the crown to the abutment in the patient’s mouth.
Retrievability: Unlike standard cement-retained options, the crown in a screwmentable restoration includes an access hole to maintain retrievability.

Screwmentable Restorations
Screwmentable restorations combine features of both cement and screw retention.
Clinical Process: The abutment and crown come separately, and the doctor cements the crown to the abutment in the patient’s mouth.
