Abstract

Aim — to evaluate the results of treatment of patients with severe atrophy of the upper jaw (class VI atrophy according to the Cawood & Howell classification) using transnasal technique of implants placement in the immediate and long-term postoperative periods.
Materials and methods.
We observed 21 patients who were aged from 53 to 84 years with severe atrophy of the bone tissue of the alveolar process of the upper jaw to the basal level. The main causes of bone tissue deficiency in the upper jaw were: peri-implantitis (n=3); periapical leassures (n=10); long-term adentia and expereance of removable dentures (n=8). The method of 4—6 implants placement was chosen as a method of rehabilitation of patients, including two transnasal, two zygomatic and in some cases two pterygoid implants with immediate loading using temporary acrylic prosthesis reinforced with a titanium bar.
Results.
All patients show a positive effect of complex treatment using the transnasal technique of implant placement. We did not observe a single complication associated with the transnasal technique that resulted in loss or removal of the implant. All patients were rehabilitated and had positive treatment dynamics, including a long-term follow-up period from 12 to 36 months.
Conclusion.
The analysis of the treatment of patients with severe atrophy of the edentulous upper jaw using the transnasal dental implantation technique allows us to speak about its effectiveness and recommend it as a method of choice and as an alternative to the technique for four zygomatic implants placement. However, it is worth noting that this technique requires further long-term observation of patients due to the small accumulated world experience and the few publications on this topic. It would be interesting to conduct comparative studies of long-term treatment results using the technique of four zygomatic implants placement and a hybrid protocol for two zygomatic and two transnasal implants placement.
