The article discusses the role and importance of
phraseology in the development and enrichment of speech in
primary school students. The influence and special role of
phraseology in increasing the clarity and effectiveness of speech
was also analyzed because the speech of primary school
students was norrow.

One of the limiting factors for the
widespread implantation is the insufficient
volume of bone tissue for the installation of
the implant.[1] The process of dental
implantation into the frontal part of the
upper jaw, which is atrophied at a high
level or accompanied by a vertical fracture
of the teeth, requires additional bone
products and a long rehabilitation period,
the reason for this is, that the vestibular
plate of the frontal part of the upper jaw is
thin and it is characterized by a fracture
during tooth extraction.[2] Bone atrophy
after tooth extraction is one of the most
important issues of modern dentistry, since
significant atrophy of the bone tissue of the
jaws makes it impossible to perform
intraosseous implantation, and also creates
serious difficulties in the orthopedic
treatment of patients.[3]
The purpose of the study.
The study of
dental implantation using the "root
membrane" method in the upper jaw to
increase the efficiency of preservation of
the dental-alveolar segment.
Research objectives:
1. The study of dental implantation by the
“root membrane" method carried out due
to complications of caries or fracture of
teeth on the example of clinical,
radiological and laboratory parameters.
2. Comparison of the results of the
indicators of the traditional method and
the "root membrane" method, to improve
the efficiency of preserving the dental-
alveolar segment.
Materials and methods :
We treated 22
patients, aged 35 to 50 years, who came to
us for dental implantation with partial
dental adentia in the anterior part of the
upper
jaw,
with
chronic
apical
periodontitis and a tooth root fracture
when it was impossible to restore these
teeth with orthopedic structures.. There
are 12 men and 10 women among them.

Methods
: Clinical research methods,
Radiation research methods (CBCT),
Histological research methods.
Clinical example
The patient is 45 years old. Complaints:
pain in 21 teeth; fracture in the crown of
the tooth; the remainder of 1/3 of the
crown of the tooth. Diagnosis: Chronic
periodontitis of the 21st tooth.
Treatment plan: Traditional immediate
implantation

subject to endodontic treatment. After
antiseptic treatment in the oral cavity, local
infiltration anesthesia was performed.

The "root membrane" method
This method is also known as partial
extraction
therapy,
root
membrane
method, and partial root retention. It is
aimed at preserving two-thirds of the
buccal part of the root in the nest so that
the periodontium, along with the bundle
bone and the buccal bone, remains
intact.[4] The buccal bone has a bilateral
blood supply from the gum from above and
the periodontal from below. After tooth
extraction, the buccal bone is deprived of
blood supply from the orbit, and this leads
to the loss of part of the buccal bone. The
root section preserves the periodontal
attachment apparatus, which includes the
periodontal ligament (PDL)[5], attachment
fibers, vascularization, root cement, bundle
bone and alveolar bone. The root fragment
remains vital and intact and prevents the
expected remodeling of the nest after
extraction, as well as supports the
cheek/facial tissues.
A clinical example using the root
membrane method
The patient is aged 35 years. Complaints:
pain in the 12th tooth; fracture in the
crown of the tooth; aesthetic discomfort.
Diagnosis: Chronic periodontitis of the
12th tooth (entodontic treatment is
unprofitable).
Treatment plan: Implantation by Root
membrane method.

Research results:
In the postoperative period, the patients
underwent antibacterial therapy for 5-7
days, if possible taking into account the
sensitivity of the seeded microflora. The
patients
complained
only
of
a
postoperative wound, moderate pain and
swelling. Soreness in the area of the
surgical wound stopped for 2-3 days. The
skin and oral mucosa in the area of the
surgical field are clean, not hyperemic.
Moderate swelling of soft tissues was
observed in the wound area for 2-3 days.
The patients were given daily irrigation of
wounds. The stitches were removed on day
7-8.
When checking patients who were treated
by the traditional method, it was
determined that 2.6 ± 1.5 months were
spent for osseointegration. the methods are
set. In addition, osteoresorption was
observed in the vestibular plate, that is,
changes from 11.14± 1.2mm were
observed before surgery and up to 6.8±
1.5mm after surgery. At the same time,
changes in the interdental papillae and the
zenith of the gingival contour, changes in
the biotype of soft tissues, fixation of the
vestibular bone wall contributed to a
decrease in aesthetic results. At the same
time, when carrying out the established
methods of checking patients treated with
the root membrane method, it was
revealed that it took 1.8 ± 0.7 months for
osseointegration. In addition, noticeable
changes
were
detected
during
osteoresobtion of the vestibular plate, i.e.
before s
urgery 9.14 ± 0.8mm and after
surgery 8.6 ± 0.2mm.
Thus, it can be said that the operation leads
to
continuous
and
predictable
osseointegration by minimizing the loss of
cheek bones caused by the remodeling of
the socket, which occurs after extraction.
Conclusion:
As the study shows, the reason is that when
a fragment of the buccal root is
intentionally left, the blood supply will be
maintained
uninterrupted,
and,
consequently, the dimensions of the
alveolar process can be preserved. Based
on these data, we can conclude that the
root membrane method is a safe treatment
method that ensures a high percentage of
implantation success. In addition, this
unique technique can ensure the stability
of the size of facial and soft tissues around
the implantation site without the use of
additional biomaterials, such as bone
grafts. The dental fibers preserved in the
root fragment enhances the aesthetics of
soft tissues when they are in the process of
aesthetic immediate implant placement.
