Пациентам выполняли конусно-лучевую томографию зубочелюстной системы и панорамную
зонографию (ортопантомограмма, снимок височно-нижнечелюстных суставов). Обследования
выполнены на конусно-лучевом томографе PaxZenith 3D фирмы “Vatech”. Использовались основные методики конусно-лучевой томографии: двух челюстей в окклюзии, средней зоны лица,
придаточных пазух носа, височной кости. Исследования проводились на этапе планирования,
послеоперационного контроля дентальной имплантации в течение реабилитационного периода. Важными анатомическими образованиями при планировании дентальной имплантации являются нижнечелюстной канал, полость носа и полость гайморовой пазухи. Описаны результаты использования конусно-лучевой томографии и панорамной зонографии при планировании и
послеоперационном контроле результатов дентальной имплантации. Показаны преимущества
каждого рентгенологического метода. Обоснована перспективность комбинации конусно-лучевой томографии и панорамной зонографии в практике дентальной имплантации.
Patients were performed cone-beam tomography and panoramic dental
systems. Surveys were carried out on cone beam tomography PaxZenith 3D firm “Vatech”. Main methods
used cone-beam tomography: two jaws in occlusion of the midface, sinuses, temporal bone.
The studies were conducted at the planning stage, postoperative monitoring of dental implantation,
during the rehabilitation period. The important anatomical structures in the planning of dental implants
are the mandibular canal, nasal cavity and the maxillary sinus cavity.
There were examined 80 patients and divided into three groups. The first group (25 patients
were carried out planning of surgical interventions and post-operative monitoring only on the
basis of panoramic zonography data. In the second group (25 patients) there the data were evaluated
using 3D cone-beam computed tomography and panoramic zonography. The third group (30 patients) —
planning and monitoring of dental implant surgery was carried out using only the cone-beam tomography.
The first group of patients had incorrect placement of implants (5 persons). The main causes of which was distortion of the subject (upper and lower jaw) in size and shape, which led to the wrong
choice of size and diameter of the implant to the perforation of the maxillary sinus and the upper wall
of the mandibular canal. The second and third groups had not such complications, but the third group
patients had complications as osteointegrations disorder between implant and osseous tissue.
When performing the panoramic X-ray it was possible comprehensive assessment of
dental system as a whole, taking account of the temporomandibular joint, the adjacent parts of the
maxillary sinuses. The use of cone-beam tomography in all phases of dental implantation to avoid
errors due to incorrect installation of the implant helps to reveal the full dentition comorbidities and
upper respiratory tract, but is not sufficiently informative to monitor osseointegration before installing
the abutment. These cone-beam CT scanner, complemented by panoramic X-ray give an objective
evaluation of information in the planning stages and the stages of post-operative monitoring, avoid
complications.
