| Subperiosteal implants |
The name comes from the Latin sub - meaning "under" and periosteum - "periosteum", ie. below the periosteum. Indeed, these implants we place on the bone and below the peritoneum.
Please read this information carefully, which will help you better understand the treatment with subperiosteal implants that you may need.
The placement of dental implants allows the construction of fixed bridges, alternatives to removable dentures, or eventual their stabilization. Unlike intraosal / intraosseous / implants, subperiosteals do not require a particularly large amount of bone.
However, an X-ray examination, as well as an analysis of jaw models, is necessary to properly plan the surgical stage of implantation and evaluate prosthetic options.
Subperiosteal implants (SPIs) were the first dental implants used in modern implantology (the 1930s). We abandoned them for a long time due to the fact, that they gave inflammation to the bone with subsequent melting. This was due to the poor design of the SPI - a rough and thick construction with small open spaces. Subsequently, we developed a design with extended end bands and wide-open spaces in their construction, which allows the bone to feed properly and today the results when we use the SPIs as a clinical success are comparable to those of intraosal implants. SPIs are a good alternative to intraosal implants, which in many cases, due to insufficient bone volume, require bone grafting and a better alternative to mobile dentures.
Surgery for the placement of subperiosteal implants is performed in 2 phases; first - taking a bone imprint and second - placing the implant. The surgery is non-traumatic and we perform without any problem in the dentist's office. However, sometimes we perform the operation under antibiotic protection for security reasons. Simple local anesthesia is enough to provide perfect operational control.
Post-operative complications are minimal. The two mandatory day-to-day examinations for specific wound care also contribute to this.
A swelling can occur for several days, without pain or with mild soreness, which can be easily soothed with the painkiller.
We remove stitches after eight to ten days.
At these types of implants, we do not wait for a 6-month period to integrate into the bone, and prosthetics can begin days after the removal of the sutures. The periosteum (peritoneum) and the lining of the gums heal over on them for no more than 2 weeks.
We make SPIs from titanium alloy, but we can also make them from another alloy (most commonly chromium-cobalt) intended for dental purposes.
In principle, we do crowns and bridges over implants of metal- ceramics or photo polymer, and the metal base in both cases must be of the same alloy as the implant itself, in order to avoid electrical stress between the prosthesis and the implant, ie. n. "Bi / poly / metal".
At values of this electrical voltage above 100 mV, such as the natural electrical voltage of a living cell, bone cell damage occurs, which is detrimental to the implant. In cases where the implant is of another alloy, we do crowns and bridges of the same alloy for the same reasons. Sometimes, when the gum atrophy is so large that the face looks sunken / so-called „senile face“ / bridges cannot fill the space between the teeth, lips and cheeks, to restore the normal appearance of the face. In these cases, we put over SPIs etc. "Semi-movable prostheses" on spherical joints.
The supports created by the subperiosteal implants are perfectly stable and enable normal function and aesthetics to achieve. Your involvement in special care is also very important. We perform the hygiene of the prostheses over the implants with special interdental brushes and threads.
After prosthetics, we have to perform a series of examinations: namely after one month, three months, six months and one year. Then - twice a year until the third year, and then - once a year, unless the need arises.
Implantology is currently a reliable and routine technique in dentistry.
The subperiosteal implants we offer - our own patent - are some of the best implants in their class in Europe and the world. We guarantee 100% success rate. These results are lasting in the treatment with total subperiosteal implant (over 20 years). In the treatment with partial subperiosteal implants in area the molars, combined with natural teeth or intraosal implants in the frontal region, after 8 to 10 years, inflammatory processes begin around the neck of the implant, because the bone under it atrophies. Then the implant becomes movable, which is not healthy for him and the bridge. It is a good idea to remove and rebuild the corresponding subperiosteal implant with the first symptoms of this nature.
The metal-ceramic structures we are offering will be made of modern hi-grade fluorescent ceramics Ceramco III - USA, and the photo polymeric ones - from Megadenta - Germany, the latest generation of micro hybrid materials used in dental technology.
The method of subperiosteal implantation has long discouraged patients for several reasons. First of all, the unpopularity of the method and the suggestion of patients by not cognizant dentists that this is an old and unreliable method. Secondly, the two surgical interventions - one for bone imprinting and the other for implant placement.
Thirdly, the aggressive advertisement of the Korega adhesive denture. The advertisement, however, is silent on an overriding fact - the overdose of the microelement zinc contained in this cream. When overdose of zinc in the body cannot absorb iron and copper and develop anemia.
Therefore, subperiosteal implantation is an alternative to intra-bone and mobile dentures. Moreover, in many cases, subperiosteal implantation is the only treatment option available.
With the emergence and development of computer-assisted methods / CAD / CAM /, this method has entered a new stage of its development, which has led it to take its worthy place in implant science and practice.
New to the method, thanks to CAD / CAM technology, is the ability to shorten one surgery - the operation of taking a bone imprint to make the implant itself. We do this by designing a jawbone on the scanner data using specialized software and a computer-controlled machine. This is a revolution in the field, moreover, that this model is much more accurate than the bone imprint model, which in turn makes it possible to produce a much more accurate implant, which results in higher success rates.
Finally yet importantly, the method of subperiosteal implantation is also much cheaper than the method used in such cases of bone implantation.
These few clarifications are intend to inform you about the treatment we can provide. More information on subperiosteal implants you can find at pfhristov@yahoo.com. For a photo gallery of subperiosteal implants, see Book.
