Clinical
and radiographic evaluation of
efficiency the method of intraoperative prophylaxis of postextractive
alveolar bone atrophy using bioresorbable
membrans
One of the basic
problem of the first
stomatological aid provision is recovery of
integrity of the dentition , that achieved by use the orthopedic constructions with
fixation on alveolar bone , teeth , and
implants. But, because of
next atrophy and deformation of
alveolar bone , prosthetics ger
difficult – is deteriorates the quality of fixation and aesthetic characteristics of prostheses.
The applying direct tissue regeneration
by local use of bioresorbable membrans biological and synthetic origin allow to achieve satisfactory result
as optimization of conditions for processes of
bone formation in the hole tooth extraction.
The purpose of
investigation – is to prevent the developing of postextractive atrophy of
alveolar bone by intraoperational use of
bioresorbable membrans based on FRP.
Materials and methods
The
investigation included 36 patients with
chronic and aggravated chronic
peridontitis od teeth of frontal group. The patients were divided by the method
of closing hole tooth extraction . The patients of main group (12 people)
closed the alveole by membrabe based on
FRP. The patient of first control group
the alveole of extract tooth closed by synthetic membrane BioGide. In second control group
not used any foreign materilas – the
alveole healed on its own under blood clot. Results estimated by use
radiographic method
investigation .
Patients of main group
the alveole closed by membrane, performed from platelet rich plasma.
Results of
investigation and analysis
At the next day after opeation all patients
in all groups of comparation noticed
insignificant soreness of soft tissues in surgical injure. On 3rd day of treatment in 9 patients of second control
group observed expressive and moderate
posttraumatic edema, and hyperaemia of mucosa , soreness of soft tissues during palpation. Narrowing
of local inflammatory reactions in 9( 75 % ) patients in second control group
observed just on 6-7 day. In last 3 (25%)
of patients, at the background of developing alveolitis, the local
inflammamtory reactions decreased by
10 day of postoperative period.
In first control group ,
where the alveole of extracted tooth
closed by membrane Bio-Gide, on 3-5 days
after operation noticed moderate
posttraumatic edema in 5 patients ( 41,7 %), not significant hyperaemia of
mucosa in extracted tooth - in 7
patients (58,3 %) . The weakly expressive soreness during the palpation of soft
tissues in area of surgical injure was
oticed in all patients of this group.
In main group , where the
postextractive alveole closed by
membrane based on FRP, on 3-5 day after tooth extraction noticed the absence of
posttraumatic edema and hyperaemia of
mucosa in place of trauma.
The estimation of indexes
showed that the most formed bone determined in 3-6 month of observation.
We can make a conclusion,
that use the barrier membrane in
postextractive period optimizate rates of
bone formation by osteoinductive and osteoconductive properties and promotes the prophylaxis of atrophic
processes.
Conclusions:
1.
The dynamics
of the change of local clinical symptoms in groups of observation testified by
, that the less expressive local
inflammatory reactions to surgical
injure registrated in patients of main
group, where used membrane based on FRP.
The more expressive inflammatory processes in condition of use barrier
membrane Bio-Gide. The most expressive and prolonged effect characterised by
local inflammation in case of traditional conduct of postextractive alveole
under blood clot
2.
Radiographic indexes demonstates high
rates of osteogenesis in patients of
main group with use FRP-technology, with completion of processes of
mineralization of regenant after 6 month after tooth extraction. The healing of
alveole under blood slot accompained more slow osteogenesis. The first signs
of immature bone tissues formation appeared by 6 month.
