Ablation of Prosthetic Work


Ablation of a prosthetic work

Prosthetic works are pieces designed to restore the morphology and functionality of the dental arches that deteriorate with tooth loss.

They are made through close collaboration between the dentist and the dental technician, resulting in dentures that meet the patient’s requirements.

Prosthetic work can be of several types and depending on the number of teeth present, at which level they are aggregated, we have, most commonly, the following types of prostheses:

  • Unidental dentures – their role is to aggregaate at the level of a tooth that has undergone changes.

These changes can be congenital defects (dwarfism, rotations), dyschromia (following endodontic treatment, following the consumption of chromogenic foods) or destruction (through caries or fractures).

The condition for a unidental prosthesis to be fitted is that the tooth must have a structure that allows the prosthesis to be inserted and retained.

The tooth must have sufficient strength so that the prosthetic work does not damage it further.

Once fitted, dentures faithfully imitate the natural tooth, giving the patient a feeling of well-being and comfort.

  • Dental bridges – this type of prosthetic work is applied when there is an edentulous gap in the dental arch, but it is bordered by healthy teeth capable of supporting the dental bridge.

The teeth that border the edentulous space are called abutment teeth and will be covered with dental crowns, while the teeth that will replace the lost ones are called bridgework.

The bridge bodies will have a tangential relationship with the gum to create the natural appearance.

  • Full dentures – are applied when the oral cavity has lost all of the teeth, on one or both arches.

In this case, as a first step it is checked that the bone and mucosal support are well conformed to allow the application of a full denture. If there are bone bumps in the oral cavity that may cause the denture to tip, the bone is regularized and then the denture is continued.

Prosthetic work has a varied prognosis of durability, which depends a lot on certain factors such as the hygiene of the patient, the condition of the remaining teeth, the number of teeth remaining in the arches and the material and technique used.

After a certain period of time, patients decide to replace their prosthetic work for personal reasons, whether for appearance (metal work, acrylic work that has deteriorated, ceramic that has come loose from the crowns) or functional reasons (unusability, decayed teeth under the work, periodontal problems).

In this case, ablation of dentures is performed.

Ablation of a prosthetic restoration is the removal of the restoration by cutting it with special cutters, called ablation cutters. This involves cutting the prosthetic crowns longitudinally and then removing them from the abutment teeth.

Through ablation the dentist will create longitudinal grooves in the teeth to which the denture is added. Once these are created, using a larger instrument (sometimes a lifter) the grooves are widened and the dentures are removed from the teeth.

It is painless for the patient and ablation is the most atraumatic method of removing prosthetic work.
