In this section, you can buy plastic abutments. These are made of ashless plastic, which is used as the basis for the manufacture of individual abutments. The range includes both angled and straight plastic abutments. The essence of the method of manufacturing individual supporting elements consists in the fact that the dental technician refines the plastic blank of the castable abutment until it perfectly fits the anatomical features of the patient (receives an individual template for casting). At the processing stage, the castable abutment is cut off, and a layer of wax is applied to its surface from which the base for the future crown is formed. Then the template is placed in a plastic refractory composition (special gypsum with minimal thermal expansion). Thus, the plastic abutment forms an imprint in the refractory mass. After that, without removing the plastic part, molten metal is poured into the cavity. At the same time, plastic and wax burn out completely leaving no traces. After cooling and removing from the refractory material, a metal abutment castable according to an individual template is available to the specialist.
Benefits of custom abutments over standard abutments
In many cases, standard abutments are sufficient and are available in a wide range of heights according to the level of gum support. You can also buy angled and straight abutments. However, the supporting element of the prosthesis, made considering the individual characteristics of the patient, still has severaladvantages:
- Perfect anatomical compatibility of castable abutments, considering the position of the implant in the jaw. This will allow the crown or bridge to be fabricated with a good passive fit and evenly distribute the load on the dental implant.
- Good result in the aesthetic zone, especially if the abutment is cast in zirconia. Even if this is not the case, then the edge of the crown on the castable abutment is covered by the gum. Accurate fit in the gum line is achieved due to special wax. A plastic-based specialist forms an anatomically accurate shape, which is then cast in metal.
- The durability of the restoration on castable abutments is also higher. This is achieved through a more precise fit and soft tissue contact with the abutment neck.
- Gingival support and a more accurate fit into the natural contour of soft tissues.
- Safety – the risk of peri-implantitis is much lower compared to standard cement-retained abutments.
In addition to casting, there is another way to make custom abutments. This is a progressive CAD/CAM technology. There, the algorithm is somewhat different:
- Scanning the oral cavity. It is carried out after the engraftment of the implant. A special scan marker is placed in the implant during the scan.
- Based on the resulting digital file, you can print a physical 3D model of the jaw, but this is not necessary. It is possible to design a future crown or bridge structure on a computer bypassing the stage of a physical model. For individual abutments, it is also possible to design a digital model.
- An individual abutment is machined on a high-precision machine with digital program control.
However, it is much cheaper to get an individual abutment using polymer burn-out abutments.
Features of the use of castable abutments from Uniqa Dental
Burnt-out plastic blanks are very convenient and functional, although they require a high level of skill when forming the anatomical shape of an individual abutment. Through our website, you can order different options for injection molded support elements, and here are the nuances you should take into consideration:
- The shape and angle of the castable abutment. It is often necessary to install dental implants with a significant angle of deviation relative to the bone. Straight abutments will not allow you to install a full-fledged crown. For these cases it is necessary to buy angled abutments. 15° angled abutments are available on our website.
- Gingival height and shape. Each person’s soft tissues are unique. Moreover, the level of the gums can change over time or as a result of previous diseases. An ideal aesthetic result can only be achieved with a customized abutment. It is possible to buy castable abutments with several skirt heights from 1 to 4 mm enabling you to achieve the ideal height of the gums.
- Material Uniqa Dental burnout abutments are made of ashless polymer. The key advantage of ashless plastic is complete evaporation under the influence of high temperatures without traces and ash residue. This means that in the process of pouring the abutment model from metal, no fragments are left from the burnt plastic abutment, and no bubbles formed by gases during combustion will remain in the refractory mold. As a result, the part is monolithic and cast with the highest precision.
- Machinability. The quality of the bridge prosthesis directly depends on the support. These are abutments. Castable abutments allow you to make a group support for a bridge prosthesis. Correctly select the height and compensate for mismatches in the angles of inclination of adjacent supporting elements. Truth is limited. Due to this, it is possible to achieve maximum accuracy, which means that the fit will be ideal with a uniform distribution of the load. Ease of processing allows the manufacture of individual abutments for both cemented and screw-retained.
Why is it profitable to buy castable abutments from Uniqa Dental
Many companies produce similar products, but even in a competitive environment, the offer from Uniqa Dental is interesting. If you decide to work with Uniqa Dental, you will receive:
- Free shipping throughout the USA from as little as one piece. You can order any unit of production, regardless of the price.
- Excellent quality – not only for castable abutments. Although the highest quality ashless polymer is also used here. The remaining components, from implants to screws for fixing the abutment, are made of Grade 23 titanium alloy, which is almost equal in strength to Grade 5, but surpasses it in plasticity. And this is critical for small and thin-walled parts.
- A wide range of components for all popular platforms of dental prosthetics.
- Access to an electronic library with digital images of implants, abutments and other components. This is a necessary resource for the manufacture of prostheses in the CAD/CAM system.
