Installation of an implant — difficult surgical intervention. During the procedure the doctor implants (screws in) in a bone an artificial titanic root to the place of the absent tooth. And the stomatologist has to be trained carefully for operation — depends on it, how successfully it will take place.
It is about exact diagnostics. It is necessary to estimate a condition of a bone tissue and as the implant will interact with surrounding fabrics, to define its positioning. The doctor has to have a full picture of an initial situation to recreate one tooth or a number. At a stage of diagnostics even the slightest error is inadmissible.
In medicine there is a method which provides the most exact result. It is a computer tomography, or 3D - diagnostics.
What is the computer tomography (CT)
It is a noninvasive method of a research by means of x-ray emission. It allows to estimate a condition of a dentoalveolar system — the parodont, area of the planned implantation — a bone tissue, the next teeth.
Some doctors are still limited to result of an ortopantogramma. But the panoramic exposure of jaws provides the two-dimensional flat image, less informative from the point of view of stomatologists: one object is blocked by another, it is impossible to determine thickness of bones and fangs.
Only 3D - a research will give a full and reliable picture. Any other method has no same accuracy, clearness and objectivity.
Method essence
Relevance of x-ray films in 3D for implantology
Muscles, bones and cavities differently pass X-ray — the effect of a X-ray analysis in general and a computer tomography in particular is based on it.
The beam passes through a body of the person and is caught by the tomograph detector. After completion of a research the device issues up to 600 consecutive pictures. They are processed and unite in one three-dimensional model. The doctor receives visualization of jaws, all bone structures of the patient in three planes — frontal, axial and sagittal. At the same time the real model — with preservation of all sizes turns out.
Advantages 3D - diagnostics
The research in three planes is irreplaceable at implantation. Here main advantages of approach:
Assessment of anatomic features. The stomatologist estimates jaws and a bone tissue, determines width and height of an alveolar shoot in the field of the planned implantation, estimates arrangement of fangs of rather Highmore's bosom, the mandibular channel and other anatomical structures.
Convenience. The stomatologist can increase and turn the picture that in details and from different foreshortenings and corners to consider it. It will help to define unmistakably the place of implantation, diameter, length and an inclination of a titanic root.
Implantation planning. Results of a tomography help to pick up optimum modification and the size of an implant, to predict the operation course, etc.
Advantages to patients. The procedure is painless, takes only 2-3 minutes. The patient sees at once how his teeth after implantologichesky treatment will look.
Guarantee of excellent result. 3D - the picture allows the stomatologist to plan treatment, to see and prevent any errors, complications and other consequences.
Important!
If the doctor does not ask the patient to pass a computer tomography before installation of an implant, such stomatologist should not trust the health. Effective implantologichesky treatment is impossible without preliminary KT.
What incidents can occur if not to carry out preliminary 3D - diagnostics?
Injury of the next teeth, soft tissues of a dentoalveolar system
Discrepancy of the sizes of an implant to depth of the drilled opening
Complications
Unsatisfactory result in general
Indications to 3D - diagnostics
Relevance of x-ray films in 3D for implantology
KT — one of widespread diagnostic methods in stomatology. But it is applied not only to implantation, but also in other cases. There are indications:
skull fracture — usually KT combine in this case with MRT to obtain information on damages of bone structures and a brain;
injury of jaws, for example, change;
anomalies of development of a dentoalveolar system — malocclusion, a sky crevice, a retention or an allotopia of teeth;
orthodontic treatment — its planning and stage-by-stage control (for example, installation of a breket-system);
identification of new growths of bone structures;
assessment of temporal and mandibular joints — their building, pathological changes (for example, dislocation, arthrosis).
Relevance of x-ray films in 3D for implantology
Thus, the computer tomography is shown for diagnostics, development of the scheme of treatment, control of results. Not only stomatologists, but also other doctors, for example, otolaryngologists can apply the last.
As the procedure is carried out
During inspection the patient sits or costs. Around his head the X-ray tube and the sensor rotates and takes pictures. The procedure lasts 2–3 minutes, takes place imperceptibly for the patient — she does not cause discomfort, pain and other feelings, does not demand special preparation.
