Over the past 20 years, dental implant technology worldwide has come a long way. Today, implantation has become the most reliable and high-quality option for restoring a missing tooth or several teeth, allowing doctors to abandon the options for installing bridges based on healthy teeth.
More than 10 million implants are installed annually in the world. And data from long-term observations show that implants can serve an unlimited period if the immunity is in a satisfactory condition.
Nevertheless, the surgeon can only install an implant if the depth and width of the bone tissue make it possible to place the implant and position it correctly (i.e. set it in such a way that the surgeon can accurately install the crown on the implant without breaking the bite) and the fit of the future crown to adjacent teeth).
Unfortunately, if a patient does not have a tooth or a group of teeth for a long time, the bone tissue atrophies (becomes thinner) in this place. Depending on the actual bone amount (which can be accurately measured by 3D tomography directly in our clinic), the surgeon selects the optimal implant size. The first indicator is the diameter of the implant (usually from 3 mm to 6.5 mm). The second indicator is the length of the implant (usually from 8 mm to 21 mm).
The more massive (wider and longer) the implant - the more securely it would be fixed in the bone and the longer it would serve. BUT! The size of the implant is only 50% success, the remaining 50% is entirely in the hands of the implant dentist (planning, positioning, adherence to staging protocols, etc.)
Sometimes the patient's bones amount is not enough to place the implant. In such cases, there are separate solutions for the upper and lower jaw.
Sinus lifting (open or closed) is the most common option for increasing the bone tissue amount in the maxillary sinuses, where bone atrophy occurs most often. The operation is performed on an outpatient basis under local anesthesia, it takes 1 - 1.5 hours. After the procedure, in 80% of cases, it is necessary to wait 6 months for complete engraftment of bone material.
In approximately 20% of cases, patients might have a contraindication for the sinus lift which includes inflammatory processes in the maxillary sinuses (sinusitis, maxillary sinusitis), and cysts in the sinuses. In this case, the patient first undergoes treatment at the hospital base under the supervision of an ENT specialist or maxillofacial surgeon. Such treatment can be done in Minsk or any other big city. Typically, treatment of sinusitis takes from 6 to 15 months, and after that, the sinus lift is carried out.
If you carefully read the previous section on implantation in the upper jaw, then it will be easy for you to understand all the advantages of zygomatic implants:
Next, we will tell how and in what order our doctors apply these or other methods and at what stage the only choice is cheekbone implantation.
