Introduction:
Restoration of teeth with subtotal or total destruction of the crown
part is one of the urgent problems of dentistry. One of the methods of solving this
problem is the preservation of the roots of teeth destroyed in bifurcation by
premolarization of molars (coronary-radicular separation). At the same time, defects
and deformations of the dentition, atrophy of the alveolar processes are prevented, and
the possibility of transmitting masticatory pressure naturally through the periodontium
is preserved.
In 99% of cases, in patients with destroyed bifurcation of the molars of the
mandibular teeth, 3.6, 4.6, 3.7, 4.7 teeth are removed, but under certain conditions, these
teeth can be preserved and their rational prosthetics can be carried out.
To preserve the teeth, namely the molars of the lower jaw, less often the upper
jaw, when the focus of bone destruction is located in the area of bifurcation or
trifurcation, surgical treatment is used, namely coronoradicular separation.
Keywords: subtotal and total destruction of dental crowns, cast stump pin inlays
and coronary-radicular separation (molar premolarization).
Study aim:
To evaluate the effectiveness of orthopedic treatment by using cast
stump pin inlays with total destruction of the crown part destroyed at the bifurcation of
the tooth by premolarization.
Methodologies:
We performed premolarization (coronary-radicular separation)
of molars in 6 patients with destroyed bifurcation of the tooth. The method of treatment
was carried out in middle-aged and elderly patients on the molars of the lower jaw.
Results:
The restoration of teeth was carried out in several stages. At the first
stage, the coronary-radicular separation of the roots was carried out with a diamond bur
along the bifurcation line, the molar was premolarized with the filling of the interroot
space with bone material.
At the second stage, after 7 days, an objective and X-ray assessment of the tooth
condition was performed.
In an objective study, two stumps of the tooth are located in the area of this tooth,
standing singly above the gum level. Percussion is painless, there is no mobility,
584
palpation is painless along the transitional fold.
On X-ray examination: on a sighting radiograph, the free-standing roots of the
tooth are visualized.
The periodontal gap is not expanded; the root canals are sealed to the tip.
At the next stage, the cast stump pin is manufactured, the pin is packed and fixed.
After that, we remove the impression and make crowns for the tooth.
At the control examination after 7 days objectively: the mucous membrane in the
root area is pale pink, moderately moistened, painless on palpation, tooth percussion is
painless.
A follow-up examination after 6 months showed good prognostic results.
On a targeted X-ray, there is no loss of bone tissue in the area of root bifurcation.
Conclusions:
The use of the premolarization method allows to preserve teeth
with a significant destroyed crown part and bifurcation. It makes it possible to
successfully use the preserved roots of destroyed teeth, restored by cast stump pin tabs,
both independently and as a support for bridge prostheses.
