Overview examples – Before and after

Anatomic contour zirconia dental crowns were made in groups of 3-4 elements.

The patient referred for rehabilitation, mainly aesthetic, of the upper frontal area.

We were requested to improve the color and shape of the respective teeth.

Previous results following treatment with dental whitening and coronal facial fillings were unsatisfactory.

Among the alternatives proposed, the treatment plan using Anatomic Zirconia dental crowns was chosen.

Vital extractions, zirconia root-coronal restorations and an acrylate mask were performed during the prosthetic treatment.

The cement used was Ketac Cem Plus.

The possibilities for the use of cements in dentistry are vast and the dental products industry is constantly improving and innovating to increase their reliability and durability.

We can use dental cement:

  • To fill cavities from which decayed tooth extraction has been made,
  • To seal canals following endodontic treatment
  • To bond laboratory parts.

Depending on the indication, the cements have a structure adapted to each procedure to ensure maximum efficiency.

Cements used for fillings

There are two ways of filling a cavity, temporary and permanent, depending on the short and long-term prognosis of the teeth and the treatment plan. The most commonly used cements used for fillings are:

  • Zinc-phosphate cements: often used as a base under fillings, with a pulpal and dentin protective role in deep cavities.
  • Eugenol-based cements: these are those cements used in dental surgeries that have a strong eucalyptol odor, used as temporary materials. Occasionally, when the prognosis of the tooth is uncertain, temporary filling materials are used to observe the evolution of the tooth and to have easy access in case of modifications of the treatment plan.
  • Glass ionomers cements: their special feature is that after hardening they are able to release fluoride, which has a protective effect against cavities. Its bond is also highly unaffected by the presence of saliva, so it is frequently used as a filling material for areas in the immediate vicinity of the gum. It is also used as a permanent filling material for children’s primary teeth.
  • Composite materials: these are the most resistant to masticatory forces of those presented so far and have a longer life. They are used as permanent filling materials and come in many forms and consistencies. They also restore the natural color of the tooth with greater accuracy.

For all of the above materials, the major problem is bacterial penetration at the edges of the filling if they are not perfectly sealed.

Bacterial infiltration can lead to the development of carious processes under the filling.

Cements used for bonding laboratory parts

Like filling cements, the materials used for bonding prosthetic parts can be temporary or permanent.

Temporary cements, usually eugenol-based, are usually preferred for the initial bonding of prosthetic parts to observe the patient’s degree of accommodation and any interferences. Once the fitting is perfect and the surrounding tissues are healthy, the definitive cementing is continued, with zinc phosphate or glass ionomers-based materials commonly used.

Cements used in endodontic treatments

If we achieve full-length instrumentation of the root canals and no problems occur, they can be permanently filled. However, in case of uncontrollable secretions or any other circumstance requiring a delay in endodontic treatment, calcium hydroxide cements are used on a temporary basis.

The criteria for choosing a filling cement or cementing material are multiple and take into account factors such as the composition of the material, the age of the patient, the distance from the pulp chamber and the conditions found in the oral cavity.

The dentist will choose the optimal material after considering all these factors.
