Dental prosthetics
Prosthodontics is a branch of dentistry dealing with the reconstruction of lost teeth and the improvement of their aesthetics. It is often the culmination of a long process of comprehensive treatment, being at the same time its most spectacular element. The use of modern diagnostic and therapeutic methods allows for treatment with predictability that was completely unavailable until recently.

Dental prosthetics
Dental prosthetics focuses on restoring missing teeth after the loss of own teeth. It includes both removable dentures, crowns and bridges based on natural teeth, as well as prosthetic restorations supported on implants.
Prosthetics in a few steps:
- Consultation
- Planning the shape of work
- Treatment plan with cost estimate
- Proper prosthetic treatment
Digital treatment planning
Using specialized computer programs, we precisely plan and design prosthetic restorations. Digital technologies make it possible to simulate and visualize the final effects before starting treatment.
The type of restoration is selected individually, taking into account the needs and preferences of the patient. Prosthetic treatment is always the final stage of comprehensive treatment. For this reason, we always create a management plan in an interdisciplinary prosthetic-surgical-orthodontic team.
3D printing
The stage preceding the actual therapy is detailed planning of the final treatment effect using 3D simulations and diagnostic waxing on models. In the preparatory process for making crowns and bridges, there is often a need for surgical intervention in order to create optimal bone and mucosal conditions for the final restoration. In order to ensure a satisfactory final effect in terms of both functionality and aesthetics, we use temporary restorations for the time of healing. We print them on site from certified resins, based on previously made 3D scans of the patient’s teeth. This technology makes it possible to make a temporary restoration in a shape consistent with the design of the final work.
3D scanner
Intraoral scanner instead of traditional impressions with silicone masses significantly speeds up the process of making the final restoration. Immediately after taking the scan, it is possible to thoroughly analyze the ground tooth pillars and immediately make the necessary corrections. Then we send the scan electronically to the laboratory. This method is extremely helpful for patients with a strong gag reflex.
The processes taking place in the place of a lost tooth are very dynamic. There is a local atrophy of the alveolar bone and the displacement of the adjacent teeth aiming at “closing” the resulting gap. The strength of the chewing muscles is calculated on full dental arches. Reducing the number of teeth leads to overloading of the remaining ones, which results in their progressive wear, followed by loosening and finally loss. Postponing the decision to replace a lost tooth with a prosthetic bridge or dental implant may result in the need to perform orthodontic treatment and surgical restoration procedures. It is best to replace missing teeth immediately after tooth extraction or shortly after extraction (6-8 weeks). In the case of loss of permanent teeth by children, it is necessary for the orthodontist to make a ” space maintainer “, which prevents the mentioned changes.
A prosthetic bridge is a permanently cemented replacement of a missing tooth. A typical bridge consists of two crowns mounted on previously ground teeth (pillars) and a spanner replacing the missing tooth.
The decision on how to restore a missing tooth depends on two factors. Firstly, from the general health condition, secondly, from the condition of the adjacent teeth. If the teeth adjacent to the missing tooth have extensive fillings and it can be expected that in the near future it will be necessary to make prosthetic crowns on them, a reasonable solution is to make a prosthetic bridge. If the teeth are healthy or have small fillings, and the general condition does not disqualify from the implantation procedure, the best solution is an implant. It fills the gap without interfering with the tissues of the adjacent teeth, while grinding teeth for the bridge requires grinding about 70% of the hard tissues of the tooth crown.
Currently, zirconium oxide is the material of choice for prosthetic crowns and bridges. This material, due to its biocompatible properties, makes it possible to create a physical connection between the prosthetic crown and the gum. Thanks to this, the life of zirconium oxide works is much longer than that of “metal” works, i.e. made of chromium-cobalt alloys faced with porcelain. An additional advantage of works made of zirconium oxide are aesthetic values, which in the case of restorations in the anterior section cannot be overestimated.
A bridge is a restoration permanently cemented on natural teeth, unlike a denture, which is a removable restoration that requires frequent removal for hygiene purposes.
