The Dental Implant

It is a root from an alloy of titanium which aims at replacing a tooth which was lost because of various reasons. The materials from which implants are made are biocompatible and bioinert, so that the body in which they are implanted cannot reject them. In order for an implant to have the longest life possible, it must be surrounded by bone tissue of at least 1,5 – 2 mm thickness. The jaw bones start getting resorped in a natural way after we lose teeth, so that in 6 months after extractions, the lost volume can reach even 60% from the initial one. That is why, when a tooth is extracted, the doctor should be minimally invasive so that the surgical trauma is reduced to a minimum. In the same session, the surgeon has to take all measures to prevent the bone loss or to start the recovery of the extraction area, whichever the case.

The duration in time of implant prosthetic restorations depends on the correct placement of the implants in the jaw bones. The chewing forces (functionality forces) have to act in the implant´s ax so that the bone in which the implant is placed suffers a minimum remodeling process.

Over 90% of the surgical interventions in our clinic imply bone and soft tissue augmentation in order to obtain optimum esthetical and functional long term results.

Guided tissue regeneration

When the height and thickness of the bone are limited, it is necessary to make a guided bone tissue regeneration. The bone augmentation techniques include the usage of a biomaterial which maintains the bone volume:

  • bone from the patient (autologous)
  • allograft bone (from another human)
  • bone derived from animal bone (cow or horse) (heterologous bone)
  • biocompatible synthetic materials
  • membranes for tissue regeneration (resorbing and non-resorbing).

Using materials for the regeneration of soft tissue:

  • membranes made of different biocompatible materials
  • tissue grafts obtained from the patient.

In some cases, bone regeneration can be done simultaneous with the insertion of the implants. In other cases, it needs to be done before the placing of the implants, so that bone can form before they are inserted. The patient needs to wait a certain period in which the added bone is formed as a natural biological process.

Sinus lifting

It is an operation done when there isn´t enough bone, but we want to add implants in the lateral sides of the upper jaw. This implies the partial filling of the sinus, resulting in the rise of the support area which can be used to create a biomechanical support for the implants which will be inserted. The loss of teeth implies the loss of alveolar bone which supports and contains their roots. This medical condition is usually associated with the increase of air in the sinuses. Moreover, an atrophy of this kind is also associated with an inadequate bone density for stabilizing the implants and having a good result in the long term.
