A high quality implantation depends on the doctor’s qualifications, the quality of materials and the technology used.
Installation of implants is an opportunity to restore a lost tooth without affecting adjacent teeth. They are used as roots for individual crowns.
A tooth is a complex structure that can be disturbed by various diseases. The most common of these are caries and its complications, periodontal diseases. Entire complexes of preventive and therapeutic measures have been developed to prevent such conditions, and doctors are doing their best to preserve patients' natural teeth, but sometimes the removal is inevitable. In this case, the installation of dental implants can be one of the ways to solve the problem of the lack of one or more teeth.
It is important to restore the integrity of the dentition as soon as possible. And it's not just an aesthetic issue. Although the inability to smile broadly, the early appearance of wrinkles, the loss of the facial oval sharpness and the sunken cheeks also cause a lot of trouble, especially for women.
Tooth loss can also disturb physiological processes, such as digestion, which 90 % of people do not think about. In the oral cavity, mechanical processing of food and the formation of bolus occurs, and this is an important first stage of digestion. In addition, adjacent teeth can be displaced and destroyed, and the jaw can be deformed. As a result, it will be much more difficult to install a dental implant.
Indications for implantation
Modern prosthetics based on implants is possible in almost all cases, regardless of the location or extent of a dentition defect.
Dental implantation is indicated for:
- - the absence of one or more teeth,
- - bounded and free-end edentulous spaces,
- - complete absence of teeth.
Dental implants are especially necessary in cases, where there are no conditions for high-quality attachment of full or partial dentures, as well as intolerance to the materials of which removable prostheses are made.
STAGES OF TREATMENT
During a dental examination, the doctor assesses the condition of the oral cavity, dentition, mucous membrane, occlusion, conducts an x-ray examination, determines the possibility of implantation and its specific form.
In addition, in cases where the chronic diseases require monitoring, or the patient takes certain drugs, a number of examinations are conducted to evaluate the overall condition of the body. To do this, blood and urine tests, ECG, as well as a consultation with a therapist or a family doctor are performed.
Virtual model surgery with assessment of the structure and thickness of a bone, as well as the possibility of installing an implant. Implants are selected individually for each patient, depending on the clinical situation and task.
If there is a lack of bone tissue, the previous bone augmentation is carried out.
A bed for the implant (its intraosseous part) is formed in the bone tissue; a healing screw is placed above. If this is the lower jaw, the engraftment takes 3 months, on the upper jaw — 4 months.
Temporary crown installation to create the correct contour of soft tissues (gums).
The optimal material, shape and size of the crown are selected. Then it is installed on the abutment and the process is completed.
Contraindications for implant placing
Like other surgical interventions, dental implantation has a number of contraindications. They are divided into absolute and relative contraindications. The first ones include severe chronic diseases: tuberculosis, diseases of the skeletal system, in which the recovery of bones, nervous and cardiovascular systems with circulatory failure and oncological diseases are slowed down.
Relative contraindications include dental diseases, such as: stomatitis, periodontitis, malocclusion, diseases of the temporomandibular joint, bruxism, precancerous conditions of the oral mucosa, as well as thyroid pathology, high blood pressure, diabetes mellitus and others.
The installation of implants is also undesirable with poor oral hygiene, as this is a direct path to infection of the implant and surrounding tissues, and the development of peri-implantitis with subsequent rejection.
Complications of implantation
Complications are divided according to the time of occurrence:
- - during surgery: injury to adjacent mucous and bone structures, bleeding;
- - in the early stages: inflammation of the surrounding tissues, for the prevention of which anti-inflammatory and antibacterial agents are prescribed, oedema, pain, bleeding, discomfort;
- - in the long term after the end of prosthetics: complications associated with the fixation of the crown and its deformation, inflammation of the mucosa, the formation of pockets.
Specialists in the dental clinics of Kyiv and other cities of Ukraine monitor the development of dental implantology and take all measures to prevent complications, but much depends on the patient himself/herself.
Types of implants
Implants are distinguished by the material they are made of. It can be titanium, gold, zirconium, ceramics, glassy carbon and others. The most common of these is titanium. In shape, there are plate, screw, cylindrical, and tubular implants. Most of them have a porous coating, which contributes to its mechanical retention in the jaw bone and biocompatibility with it.
Implantation techniques are as follows:
- - one-stage implant placement: in this case, the implant is placed in the bone bed, its head protrudes into the oral cavity, and prosthetics begins immediately after the surgery;
- - two-stage implant placement: only the root part is placed in the bed, the mucous membrane is sutured above it, prosthetics begins 2-4-6 months (earlier on the lower jaw) after engraftment;
- - immediate implant placement: the implant is placed into the alveolar socket immediately after tooth extraction;
- - delayed implant placement is performed 2 or more months after tooth extraction, when the bone is completely rebuilt.
The cost of a dental implant is determined by many factors: the amount of bone tissue at the implant site and the need to perform additional procedures for its restoration or augmentation, the state of the gums, individual features, technology.
The price for dental implants is discussed with the doctor after initial dental examination, taking into account the number of teeth, which need to be restored.
Care for implants is the same as for natural teeth. Careful oral hygiene is needed to prevent infection and inflammation. Professional cleaning is recommended once every 6 months.
The main thing is not to take too long with implantation, and your health and smile will be safe.
During implantation, biologically compatible materials are implanted in the jawbone. This means that the process of implant integration is more successful.
The advantages of implants compared to traditional prosthetics:
- Reduction or complete elimination of injury to natural healthy teeth. They do not need to be milled for crowns.
- The ability to restore several teeth at once, including the posterior teeth from 6 to 8, on which the entire dentition rests, using fixed dentures.
- The ability to manufacture fixed dentures even in cases, where there are no teeth at all, as well as improved attachment and fixation of removable dentures.
- The implantation efficacy using modern technologies reaches 97 % and higher.

MYTHS AND QUESTIONS ANSWERS
1. Is it possible to remove a tooth and put an implant at the same time?
Yes, it is possible. According to the results of a CT scan, a surgeon can tell you about the possibility and details of the procedure.
2. What is the percentage of implant survival?
The implant undergoes a process called osteointegration. This is one type of implant integration into bone tissue. Under favorable conditions and compliance with the protocols, osteintegration is successful.
3. Which is better: bridges or implants?
Definitely, implants are better than bridges. Implant with a crown restores the missing tooth, while the adjacent teeth are not damaged unlike in the manufacture of the bridge.
