In this section, you can buy the Multi-Unit Abutment System—a prosthetic system with screw fixation of crowns and splint constructions to the abutment without the use of cement. The Multi-Unit prosthetics system is indispensable for complex reconstructions when a large part of the tooth row must be restored. While the Multi-Unit system is not designed for single restorations, it offers numerous advantages in cases of multiple restorations:
Advantages of the Multi-Unit System
- Cement Rejection at the Soft-Tissue Level: The abutment and implant are connected with a screw, eliminating cement at the interface between the implant and abutment. The crown or splint bridge structure is attached to the abutment with another screw. There is an intermediate component—the connection sleeve (see illustration below)—which is rigidly glued into the structure of crowns or splint bridges. Adhesive cement is used here, but all operations occur outside the patient’s oral cavity. After manufacturing and fitting, the prosthesis is fixed to the abutment, and the point where the screw enters the crown is sealed.This is the key difference between the Multi-Unit system and cemented abutments. All adhesives and cementitious compositions are used outside the patient’s oral cavity, which is beneficial because cement residues can cause irritation and inflammation of the gingiva. Although the cement residue at the junction of the crown and abutment is removed, the dentist can’t always reach tricky areas between the teeth, especially in splinted designs with complex configurations. For single implants, cemented crown fixation is still used.
- Permanent Abutment Fixation: The abutment is screwed in once and for all. Crowns and bridges can be changed from temporary to permanent or from a paired implant to a bridge structure for three or four teeth if additional teeth are lost over time. Throughout these manipulations, the implant remains completely protected and immobilized.
- Better Lateral Load Distribution: Compared to cement fixation, prosthetics on the Multi-Unit platform load the top of the implant less, as proven by studies. This is especially important if implants with a diameter of less than 4 mm are used. These models have a relatively thin wall in the coronal part, and there is a high risk of implant failure if the Ti-base platform is used. Additionally, the Multi-Unit system abutment not only distributes the load better but also acts as a mechanical safety guard. In the event of extreme stress, the abutment screw will break first, not the implant. Removing the broken screw is relatively easy, after which the restoration can be repaired. To prevent recurrence, it is recommended to adjust the problematic crown out of the bite.
- Reduced Micromovement at the Implant/Abutment Level: In Multi-Unit systems, micromovement is significantly lower than when using cement-retained crowns. This is crucial because there is always a micro-gap between the implant and the abutment. If the connection is movable, a “pump effect” occurs—pumping fluid with bacteria through the gingival cuff into the internal structures of soft tissues. If microflora from the oral cavity penetrates into the sterile environment of soft tissues and alveolar bone, it can cause inflammation, potentially resulting in the loss of the implant.
- Easier Achievement of Passive Fit: With screw fixation, achieving a passive fit (no internal stresses) is much simpler. This reduces the risk of loosening and breaking of the screws. The prosthesis on the Multi-Unit can be removed, adjusted, or replaced without internal stresses. Even if local overstresses remain, they are transferred to the area between the abutment and the removable sleeve, where they are easier to manage. Any micromotion that remains is located above the level of soft tissues and will not cause the pump effect or gum inflammation. All operations are straightforward and can be performed quickly and almost painlessly. In contrast, removing cemented restorations is difficult and very traumatic, which is harmful to both soft tissues and bone, as the implant can move, causing additional bone injury.
- Ideal for Complex Cases: Screw fixation of crowns works well in challenging situations with bone deficiency and the inability to line up implants along the dentition. The Multi-Unit system allows implants to be placed at different angles and even in a staggered pattern. Placing the implants at angles to each other is beneficial and recommended, as it allows for even load distribution and reduces the risk of loosening and breaking of the screws. With the Multi-Unit system, achieving a high-quality restoration of the dentition is easier (see the photo below).
- Suitable for Low Crown Heights: If the crown height is 3–4 mm, you also need to buy Multi-Unit screw-retained abutments. Cementation will not hold such a crown in the long term, and the risk of crown loss is very high.
- Easy Removal of Crowns and Bridges: When using Multi-Unit screw abutments, it is necessary to drill through the crown to reach the screw and remove the bridge structure from the abutment. With the cement fixation technique, the crown has to be physically dislodged from the abutment—a traumatic procedure with a real risk of bone damage. The impact is transmitted to the jawbone like a lever.
- Economic and Reputational Benefits for Dentists: Despite the components of the Multi-Unit system being noticeably more expensive, their use is beneficial in the long run. Complex structures on the Ti-base platform often have internal overstresses, contributing to the unscrewing of screws or the destruction of the cement layer (crowns become separated). Such problems frequently occur within a few months after the restoration is installed. There are two possible scenarios:
- The patient goes to another specialist who remakes the prosthesis. The new dentist often switches from Ti-base to Multi-Unit; the prosthesis works better, the patient is satisfied, and remains a client of the new specialist.
- You have to redo the restoration and fix problems at your own expense. These problems arise in difficult cases, and the amount of work is substantial. In any case, this negatively affects your income, although your reputation can be maintained.
List of Multi-Unit Components Available for Purchase Online
Multi-Unit D-type abutments (MUA) provide better functionality and freedom of action for the dentist, resulting in better outcomes for patients. We have already mentioned the main advantages of the screw fixation system earlier. You can buy both angled Multi-Unit abutments and straight Multi-Unit abutments from us. Please note that we offer different types of Multi-Unit abutments: integrated with a screw and two-component, where the abutment and fixation screw are separate items.
You can also choose and buy straight and angled abutments with different interface heights above the implant level. This allows us to solve the most complex prosthetic problems. For example, when there is local bone deficiency and it is necessary to install dental implants at significant angles relative to the dentition. This approach enables the avoidance of complex operations for vertical bone augmentation or open sinus lift, where the risk of complications can reach 20% or more.
Combinations of straight and angled abutments are most commonly used for full-arch restorations, including in combination with zygomatic dental implants. Multi-Unit abutments are great for conditionally removable dentures, where the dentist removes the denture once a year to clean it and treat the gums if necessary. Also, the screw-retained system with angled abutments is well-suited for cases of immediate installation of a complete reconstruction—situations where the denture begins to function within a few hours after implantation.
Multi-Unit abutments are also suitable in all cases where All-on-4 or All-on-6 implants are required. This is because it is possible to place the implants at angles to overcome anatomical limitations and distribute the masticatory load evenly in all planes. We offer Multi-Unit angled abutments with 17 and 30-degree angles. A 17-degree Multi-Unit angled abutment allows compensation for deviation angles up to 74 degrees, and the 30-degree variant can compensate for angles up to 100 degrees.
Uniqa Dental straight and angled abutments are made of Grade 23 titanium alloy, which has high strength (comparable to Grade 5 alloy) but superior plasticity. This is especially important for angular structures where the load is unevenly distributed. The screw-retained system also allows the connection between the root implant and the abutment to be brought to gingival level. This minimizes soft tissue trauma when the restoration must be removed and reinstalled, which is extremely important because soft tissue health is a crucial factor in a patient’s quality of life.
Additional Components Available:
- Healing Caps (Gingiva Formers): For the formation of the gingival socket.
- Sleeves for Straight and Angled Multi-Units: Available for both temporary and permanent dentures.
- Screws: For attaching Multi-Unit abutments to the implant as well as for attaching the prosthesis (bridge) to the Multi-Unit abutment.
