Use of tooth implants is the most modern way of restoration of the lost teeth. False teeth on implants are almost indistinguishable from the presents.
The tooth implant represents the titanic screw which is twisted into a bone, and then is replanted – osteointegrated.
The implant consists of two parts: – actually an implant – that part which is immediately implanted into a bone tissue and an abutment – a structure which is fixed to an implant. To an abutment we attach this or that orthopedic design (a crown, a bridge, an attachment).
Installation of implants is absolutely painless as it is made under local anesthesia, and at desire under sedation (narcosis).
After installation of an implant 3-6 months are necessary for its osteointegration (engraftment) – a bone accretion around the implant.
When losing teeth the standard orthopedics offers installation of bridge-like prostheses on the basic, previously prepared remained teeth, and at implantation these teeth remain untouched.
Implantation begins with planning. At first the patient is sanified (setting of seals, tooth cleaning, treatment of teeth channels) at the therapist of the stomatology and undergoes computer and tomographic research for an assessment of the condition of a bone tissue for the installation of implants. If necessary the bone tissue is increased.
The computer tomography allows to tap a form, a structure and the sizes of various structures with absolute accuracy allowing to make the optimal solution for aftertreatment, considerably facilitates the operation course at installation of an implant, allows to estimate the size and a structure of a maxillary sinus when planning operation of a sine lifting – sinus wall thickenings.
The most widespread technique is a two-stage implantation. At the beginning of the implantation, and in 3-6 months, after osteointegration is established, a prosthetic repair is made. When clinical conditions allow, both stages are made at the same time.
Aftertreatment terms at implantation depend on many factors:
- features of a bone tissue and facial skeleton;
- hygiene of the mouth;
- quantities of implantation stages;
- need of carrying out extension of a bone tissue.
Sine – lifting.
In the field of the top jaw there is a natural cavity – a maxillary sinus (sine), the volume of which is enlarged with age, due to the decrease of a bone tissue. It has an individual structure and carries out drainage function. Teeth of the top jaw sometimes even get into a maxillary a sinus with the roots. After the loss of upper teeth the bottom of a sinus can become thinner up to 1 mm of a bone. For restoration of a wall of a maxillary sinus we enter a bone substitute. This procedure is called sine lifting which is made at the time of carrying out of implantation, or several months prior to it.
Implantation and fixed prosthetics at total absence of teeth.
The number of implants necessary for aftertreatment, as well as the choice of a prosthesis design is solved individually.
On the top jaw up to 10 implants prostheses can be set, on the lower up to 8.
The technique “all on the 4th” suits not all, but is possible under certain conditions.
If the prosthesis is fixed on implants by cement – it is a fixed prosthetic repair. When bracing by means of screws – it is a conditional and removable prosthetic repair.
At standard implantation at first do a gums cut, open a bone tissue, establish an implant and put in stitches. In 3-6 months, after engraftment of an implant, we do a gums cut again and establish an implant abutment with the gingival adapter or an individual abutment. In two weeks we start production of a prosthesis.
At express implantation the phase of engraftment is passed and the abutment is established with an implant at once, but this technique has many restrictions and demands, like detailed diagnostics and a wide experience of the implantologist.
At implantation and prosthetics we don’t release the patient without temporary designs, especially in esthetically important zones. It can be the adhesive bridges fastening on the remained teeth or on temporary implants or mini-implants.
Thus your aftertreatment will be carried out in comfortable conditions and won’t affect your way of life.
