Subperiosteal dental implants

Sometimes there are situations when restoring a beautiful smile with the help of classical root-form implants is impossible, but it does not mean you have to refuse from the idea of dental implantation. Modern technologies of dental implant procedure allow to reduce the effect of relative contraindications and to avoid the absolute ones, considering all precautions. Because only in this way it is possible, after weighing all the risks and assessing the results of the examination,  to choose an alternative method and to help the patient, using no less effective implant of other type. Such implants will be subperiosteal in cases of contraindications to the root-form implant placement, yet they are called endo subperiosteal implants. What distinguishes these implants from others and why are they necessary in some cases?

Every bone in the human body is covered with periosteum – a layer of connective tissue, which is involved in the formation of new bone cells during the growth of bone in width and regeneration in case of fractures. Subperiosteal dental implants are integrated into the subperiosteal space between the periosteum and the bone, in such a way not to damage the periosteum, but also to fix the implant reliably. They are complex titanium or chrome-cobalt structures which have the shape of a saddle, expanded but thin, cover the gum as a frame and provide the same function as the implants. Such designs are necessary in case of the height deficiency of the alveolar part of the jaw and in case of bone atrophy. For producing  subperiosteal implant that is appropriate  in each individual case.  At first it is necessary to make an impression of jawbone for producing subperiosteal implant, suitable   in each individual case. The bone size of 5 mm in height is sufficient for this type of dental implant procedure.

As with other types of dental implant procedures, subperiosteal implants can be placed by using a one-stage or two-stage technique. The choice of technique depends, as in all other cases on many factors. Thus, one stage technique first involves computerized axial tomography for studying the structure and size of the jaw bone, after which the sectional image is processed, and based on findings, the implant of necessary parameters is produced. Then, it is placed and several stitches are put to close the recovery of soft tissue of the gum. Two-stage technique differs by the fact that at the beginning the surgery is performed in order to make an impression of the jawbone, and after it the whole process is similar to the one-stage technique. Thus, one stage technique is less traumatic due to modern medical methods of information visualization.

Taking into account all the indications and contraindications, your dental practitioner will recommend  you to placel the subperiosteal dental implants in the case when the size of the alveolar  process is small, and  there is no possibility to perform sinus lift for one reason or another or  the beginning of the lengthy  process of bone augmentation is not desirable.

Also a dental practitioner will give you instructions about oral hygiene and oral care after subperiosteal implants placement.
