Zirconium Crowns
Today, with the increase in aesthetic expectations and the development of technology in dentistry, zirconium is preferred more than metal-supported coatings. Zirconium is a lightweight, heat and electrically non-conductive, impact-resistant, and light-transmitting element.
Advantages:
Biocompatibility: It is a material that is not rejected by the human body, so there is no adverse reaction. It allows you to use it in your mouth for years without any concern.
No allergic reactions occur, making it preferred for patients with metal allergies.
Discoloration that is seen on the gums with metal-supported prostheses never occurs.
It reduces plaque adhesion and thus contributes to oral hygiene.
Due to its insulating property, it prevents sensitivity to cold and hot.
Disadvantages:
They are costly.
If there is any incompatibility during the production stage, it is not possible to repair it, and it needs to be remeasured and made again.
It is more fragile than metal-supported porcelain bridges in cases of a large number of missing teeth in the posterior region, as it does not have the property of flexing.
What are the treatment alternatives for aesthetically problematic cases?
Cases where implants are made instead of missing front teeth can be the most challenging cases for dentists who perform implants. There are many factors to consider for restorations to be aesthetic and functional for a long time. These include bone quality and quantity, gum symmetry, 3D position of the toothless areas and neighboring teeth, the presence of interdental papilla, and the position of the lips during speech and smiling, as well as in a resting position. Dentists and patients expect perfect aesthetic and functional results in the front teeth.
However, implant-supported restorations may not always be the most appropriate treatment option. Fixed prostheses (porcelain bridges) may be a more suitable treatment option in some cases for patients with missing front teeth. In cases where there is a large number of missing teeth, making a fixed prosthesis may be more appropriate, especially when bone grafting is necessary due to anatomical limitations and insufficient bone quantity. In cases where a large number of teeth are missing, and there is advanced bone loss in the alveolar bone, a movable partial prosthesis with an acrylic base that provides lip support can be the most appropriate treatment option for the patient.
To achieve aesthetic restorations, implants should be placed not only in places where there is sufficient bone but also in the most appropriate places. The position of the implant should be evaluated in three dimensions. Defective areas may need to be supported with bone and soft tissue grafts to place the implant in the proper position.
Restoration of toothless gaps in the aesthetic area with implants should not be performed by surgeons and prosthodontists who do not have sufficient experience. A detailed diagnosis and treatment plan should be made before starting such treatment in the anterior upper region (implant-supported restorations).
