Relevance. At the present time to resolve the complete and partial loss of teeth

in the dental practice are widely used dental implants. It is well known that from the

day of the installation of intraosseous screw implants to the final prosthetics, it will

take some time for the full course of the osteointegration process. For the onset of full-

fledged osteointegration, according to the standard clinical Protocol, it takes from 3 to

4 months, depending on which jaw the implant is placed on. If there is significant bone

atrophy in the jaws, additional surgical measures are performed to increase the volume

of bone tissue. In such cases, the osteointegration period can last up to a year, which is

a long process.

In this regard, reducing the time of orthopedic treatment of various defects of

the dentition using dental implants is of great interest among dentists. It should be noted

that according to the analysis of the literature in the world practice of dentistry, a

sufficient number of research works are being carried out in this direction. They are

mainly aimed at the possibility of immediate loading of implants after their installation

without waiting for the osteoitegration period. The development of new implant

surfaces and new clinical technologies has significantly reduced the duration of the

initial healing period up to the immediate, early loading of implants with high stability.

However, analysis of the literature data shows that clear objective indications for

immediate implant loading have not yet been determined.

Based on the above, we have set a goal to determine the indications for

immediate loading of implants according to new objective hardware research methods

that are available right at the dental chair.

To achieve this goal, the following tasks are defined:

1.

To study the indicators of torc testing of implant stability using a

dynamometer key.

2.

To study the stability of implants using the frequency-resonance method

using the MEGA ISQ device.

3.

Based on the results of testing the stability of the implants, determine the

indications for immediate loading of the implants.

M aterial and research methods:

In the world practice of dental implantology, several methods for assessing the

stability of implants are known:

* clinical (percussion, manual control of implant stability);

* pericentromere;

* TORK test (using a torque wrench);

* x-ray methods of research (including the method of densitometric assessment

of bone density);

* frequency-resonance analysis.

According to a number of authors the frequency-resonance method for

determining the stability of implants is the most modern and objective. In our work,

the torc testing method and the frequency - resonance method were used to determine

the stability of implants. For torc testing, a torque control key was used, which is a

device with a special graduated scale for wrapping implants, suprastructures and

additional accessories, allowing you to control the applied pressure. It is included in

the basic set of surgical tools of MEGAGEN for dental implantation surgery. Torc test

results using a dynamometer key were recorded during the operation of placing

implants in the corresponding artificially created bone wells after their final tightening.

The stability of implants was monitored using the frequency-resonance method

using the MEGA ISQ device from MEGAGEN (South Korea). The fourth-generation

MEGA ISQ contactless device for frequency resonance analysis is small in size,

battery-powered, and provides quick and simple measurements that can be interpreted

directly from the patient's chair. The device consists of an instrument block with a

computer analyzer, an emitter-receiver of the electromagnetic field. The method is

based on recording resonant electromagnetic vibrations of the implant and surrounding

bone when exposed to an electromagnetic field. Stability is expressed in units of the

implant stability Quotient (ISQ) on a scale from one to one hundred. Stability was

measured using this device after the final placement of the implants with a

dynamometer key. The test results according to this method were taken in the Medio-

distal and vestibular - oral directions after placing a special rod on the implants.

75 AnyRidge implants and 70 AnyOne implants from MEGAGEN (South

Korea) were subjected to stability studies. Measurements of implant stability were

performed directly at the chair at the first surgical stage and after 3-4 months.

Depending on the stability of the implants, operations were performed using a one-

stage or two-stage surgical Protocol. The immediate loading tactic was chosen taking

into account the high stability of the installed implants. According to the chosen tactic,

implants with torc test values greater than 45 n/cm and a frequency - resonance

coefficient greater than 65 units were subjected to immediate loading. As orthopedic

structures for the period of the osteointegration process, provision fixed prostheses

made of polymer materials were made. Only at the end of the period of osteointegration

were they replaced with metal-ceramic crowns or bridges. Bearing in mind that the

measurement of implant stability will be carried out after the onset of osteointegration,

preference was given to the screw method of fixing fixed prostheses.

Results obtained and their discussion

Of the 75 AnyRidge implants installed, 60 had torc test readings of more than

45 n / cm. torc test Scores of more than 45 n / cm among anyridge implants were noted

in 36 of the 70 installed ones (see table. 1).

When checking the stability of 75 AnyRidge implants with the MEGA ISQ

device, 62 of them showed a stability coefficient of more than 65 units, and 40 of the

70 anyridge implants with stability coefficient indicators of more than 65 units.

All Installed AnyRidge and AnyOne implants with high torc testing and

frequency-resonance control were subjected to immediate loading, and their number

was 145. Treatment of the remaining patients whose implants had low stability

indicators was performed according to a two-stage management Protocol. Implants

placed on the lower jaw showed higher stability values. This appears to be due to the

higher mineral density of the lower jaw bone than the upper jaw. AnyRidge implants

showed higher stability results than anyone implants. In our opinion, this is due to a

more improved design of the thread geometry and a special coating on the surface of

the AnyRidge implant. It should be noted that all implants (145 pieces) with high

stability indicators were successfully integrated and showed higher values of torc

testing and frequency-resonance control when re-measured (after 3 -4 months) than

when they were directly installed on the jaws.

Conclusions:

Thus, based on the data obtained, it can be concluded that immediate loading

of implants can be carried out in the presence of high indicators of the stability

coefficient (more than 65 units) of implants obtained using the MEGA ISQ device and

torc testing of more than 45 n / cm.
