Dental implants are currently an excellent alternative to prosthetics.

On the dental market there are many models of implants, both from leading manufacturers and not well-known, which differ not only in quality but also in cost.

To decide which dental implants are the best, you need to know not only the advantages, but also the disadvantages of the proposed models.

A dental implant consists of an implant (artificial root) that is inserted into the jaw bone in place of the lost tooth and abutment - the structure connecting the implant to the denture.

It is worth noting that in case of any breakage, the abutment, like the crown, can always be replaced, while the implant is implanted in the jaw bone forever.

Kinds

Implants are of several types, which differ in shape, strength and technology of implantation:

• Root implants have a cylindrical shape with a thread applied to the surface. They are the most popular designs. They are used only if there is a sufficient volume of bone tissue.
• Laminar implants that allow maximum penetration into the bone tissue, which will add stability to the structure. They are used when it is impossible to implant a root implant.
• Combined designs are complex. They are a combination of the two previous varieties of implants. Used in the presence of tooth defects.
• Intra mucosal implants that do not require fixation in bone tissue. They are used to stabilize removable dentures.
• Endodontically stabilized, according to most dentists, are the most reliable. When installed, there is no risk of injury to the oral mucosa. Used to lengthen and strengthen the root of the tooth.
• Subperiosteal implants are used when the patient has very thin bone tissue. They are installed under the gum and are firmly fixed between the bone and periosteum.

Implant Selection Criteria

Despite the huge selection of implant systems, it is necessary to be guided by some basic criteria:

• The implant survival. Root-shaped structures made of titanium are biocompatible with the tissues of the human body.
• Simplicity of implantation of a design. The simpler the implants are in the installation, the easier the coordination of surgical and orthopedic actions.
• The possibility of implantation without bone grafting. In this case, the duration of treatment is reduced.
• The presence of a quality certificate for the implant and the official dealer of the company in Russia. Otherwise, the possibility of falsification of the structure is not excluded.
• Durability of the titanium root.
• The presence of a microporous surface of the implant contributes to faster osseointegration than if the surface of the structure is smooth.
• Features of the thread and the method of connecting the implant with the abutment. The best option is the presence of micro-threads without a polished neck.
• The presence of an aesthetic component. Wrong choice of implant can cause a defect such as translucency through the gum. In this regard, you will need to listen to the doctor's recommendations.
• The cost of construction. Some clinics are either dealers themselves or provide significant discounts on the products of the implant manufacturer.

What to look for

Materials

To date, titanium and its alloys are recognized as the best material for the manufacture of implants.

Its advantages are that it is not rejected by the body and has high resistance and anti-corrosion properties.

It is important that the design was made of high-quality titanium (at least Grad 5), since lower-grade titanium contains impurities that impede successful osseointegration.

Construction surface

• In order for the implant to grow together with the bone tissue faster, its surface is treated in such a way as to give it a microrelief repeating the structure of the bone.
• The surface of the structure is made porous due to plasma spraying, anodizing, sandblasting, acid etching or a combination of these techniques.
• To improve osseointegration, crystals of hydroxyappatite, phosphates, which allow bone tissue to grow into the pores of the surface of the titanium root, are applied to the surface of the implant.

Implants having a polished and smooth surface fuse with bone very poorly.

Available Sizes

Russian manufacturers of implants offer a choice of at least four sizes of diameters and lengths of structures from 6 to 16 mm, which allows you to choose the implant for various clinical conditions.

A small range of designs cannot guarantee the quality of treatment.

Implant shape

• High-quality implants must be conical or have a patented platform switching system.
• This type of structure has the fastest and highest quality engraftment.
• An important point is that on such titanium roots the chewing load is correctly distributed.

Thread

The presence of different densities in different areas of bone tissue was taken into account by manufacturers of high-quality implants.

Application of several types of thread on one implant allows to ensure high-quality fixation of the structure in bone tissue in various clinical situations.

If the implant has less than two or three types of cutting, then it is worth giving up.

Instruments and equipment

• During implantation, position or marker control should be carried out.
• Therefore, the clinic should be equipped with a computer tomograph or system for orthopantomography.
• An important component of successful implantation is the presence of a cooling system.
• In order to prevent burns of bone tissue, drills in the process of preparing the bed for the implant should be cooled with saline.

Type of internal connection

The implant with the crown is connected using an abutment.

This place is one of the most fragile in most implant systems.

Often there is a fracture of the abutment or loosening of the abutment and crown.

Some implant manufacturers have introduced innovative abutment attachment to the implant.

For example, a trihedral (three-channel) connection allows you to most accurately position the abutment and crown of the tooth, and also eliminates internal stress in the metal and fracture of the structure.

Manufacturer Reputation

It is better to give preference to implants manufactured in Europe or the USA, due to the fact that the products of these manufacturers fully comply with international quality standards.

Implantologist qualifications

According to Russian law, the installation of dental implants has the right to a dental surgeon, who must undergo specialization in dental implantology.

Here is a list of documents that a specialist should have:

• Graduation diploma in dentistry.
• Certificate giving the right to engage in surgical practice.
• The presence of a document confirming the qualifications of an implantologist.

Without the above documents, the doctor does not have the right to install implants and is obliged to present them to the patient upon request.

The best option - all the documentation for review by patients posted in the reception.

In addition, the implant dentist must have a specialist diploma in implanting exactly the implant system that the patient offers.

Specialists who are members of the European Association of Implantologists and the Russian Association of Dental Implantology deserve the greatest trust.

This confirms the recognition of the doctor in the professional community.

Clinic Status

The clinic in which the implants are installed must be licensed to perform such operations.

Implant rating

To determine which dental implants are better, you need to know their percentage of survival, the frequency of complications and the life of the structures.

This requires certain statistics.

This is quite difficult to do, because there are no two identical organisms, a similar structure of bone tissue.

Qualifications and experience of specialists may also vary.

Therefore, not an expensive model, installed by a professional, can take root and last a sufficient period, but a more expensive one in the hands of a novice dentist can cause complications.

The survival rate may also be affected by the immune response of a single person.

The data on the implants given in the table differ in their characteristics and cost.

The reliability of these manufacturers is time-tested, therefore, for the success of implantation, it is necessary to find a qualified implantologist.

A place	Company and country of origin	Cost (in rubles for 1 implant)
1	Straumann (Switzerland), Astra Tech (Sweden), Nobel Biocare (Switzerland)	35000 — 55000
2	Xive Friadent (Germany) and Ankylos (Germany)	30000 — 40000
3	Bicon (USA), BioHorizons (USA), Biomet (USA)	20000 — 35000
4	MIS (Israel), AlphaBio (Israel), Ards (Israel), Implantium (South Korea)	12000 — 25000
5	Russia, Ukraine, Belarus	8000 — 15000

 

As can be seen from the table:

• The first place in the ranking is occupied by premium class constructions. They are of high quality and have a lifetime warranty. Firms along with implant systems offer modern implantation technologies, as well as train specialists.
• Second-order dental implants were created with financial support from the German government. Unlike premium models, they are cheaper, but quite high quality.
• In third place are American implants, which have average prices. They quickly take root, are securely fixed and do not cause discomfort in patients.
• Budget implants, manufacturers of Israeli firms, as well as South Korean, rank fourth in the ranking. Despite the low cost, implants are of good quality and are in good demand. The percentage of engraftment of such structures is 98 - 99 %%.
• The last place belongs to the cheapest implants produced in Russia, Belarus, Ukraine.

Reviews

Doctors reviews:

• According to doctors, Nobel implants are the most technologically advanced in the world. They have a very high percentage of engraftment and a long service life. Atrophic changes around the implant are very slow.
• Dentists also recommend Astra implants for installation, as they consider them to be of very high quality. When installed, chewing load on the bone tissue is distributed in an optimal way, which helps prevent its atrophy. The disadvantage of such designs is their high price.
• Doctors put MIS implants in first place among the constructions of the economy class, which also include the implants of Russian, Ukrainian and Belarusian production.

Patient reviews:

• I needed to restore one tooth. A year ago, I installed an Alpha BIO implant. I paid inexpensively - less than 30,000. After implantation there was no inflammation, the sensations were comfortable, the crown was firmly fixed. As a result, I have a beautiful new tooth.
• Installed two years ago inexpensive implants BioHorizons (USA). The titanium root quickly took root, is convenient in operation. There was no discomfort.
• After a long search, I chose German implants, because I believe that in Germany there can be no products of poor quality. Although the implants are quite expensive, but in the clinic they made a good discount on the installation. The root engraftment went very quickly. The presence of implants is not felt at all in the mouth.
