CONSTANT DEVELOPMENT OF MODERN IMPLANTOLOGY ENABLES IMPLANT PLACEMENT EVEN IF THE PATIENT’S NATURAL BONE IS NOT SUFFICIENT IN A GIVEN SPOT.
It is estimated that in around 40% of cases of implant treatment bone restoration and regeneration is required. It is possible thanks to the use of bone substitute biomaterials, enabling the restoration of lost bone structures.
Guided bone regeneration allows for proliferation of bone tissue in the required location in order to appropriately place the implant with regard to future prosthetic restoration. The decision about the application of guided bone regeneration is made after a radiological analysis. Sometimes such necessity will only be revealed during the procedure, because routine X-ray will not always provide a full clinical image of the surgical site.
Bone loss occurs:
- after tooth extraction- with time the process of gradual loss of the denticle, both in the maxilla and the mandible (the optimal period for placing an implant is 3-6 months after tooth extraction);
- after tooth loss due to periodontitis or mechanical injury;
- after complex and traumatic extractions, when there is significant damage to the tissues surrounding the tooth;
- in case of long-term use of partial and full dentures (due to the pressure of the denture on the bonethrough the gum, causing its degeneration).
All cases described above require bone regeneration that helps achieve a satisfying functional and aesthetic effect.
Guided bone regeneration is usually carried out together with implantation. Sometimes, in case of particularly large bone void and a lack of potential stability, bone regeneration is performed as a separate procedure, and implants are placed only after the bone tissue is formed – usually after 6-8 months.
The procedure itself consist in fixing biomaterial in the space of the planned bone regeneration and shaping it in an appropriate way. Then, everything is covered with a collagen barrier membrane and stitched up. The application of a resorbable collagen barrier membrane prevents epithelial cell growth on biomaterials and enables bone tissue growth.
At Villa Nova Dental Clinic we only use effective biomaterials (Bio-Oss, Endobon) and membranes (Bio-Gide, Osseo-Guard), which have been studied in clinical trials. They guarantee a very high proportion of successful procedures with long-lasting results.
