The influence of endosseous implant-supported metal-ceramic
and all-ceramic fixed dental
restorations on the salivation rate
According the data of number of
investigators the frequency of dental defects occurrence is about 70 % of
population of Ukraine , that causes expressed necessity in integrity of
dentition recovery. The non-removable dentures have wide application for
dentition defects replacement and for it production used non precious group of
metals and their alloys.
The significant progress
in development and improvement of implants,
methods of implantations and prosthesis allow to solve the most complicated dental problems.
Against the background of significant achievements in dental
implantation development, still observed complications of soft and hard tissues
of oral cavity, leading to inflammatory and atrophic processes, the main role of
which is material of prostheses and implants.
Therefore, the problem of
study the material for implants and suprastructures interaction in oral cavity,
it influence on human body still actual , and
was the the reason for our research.
The purpose of our
investigation is to estimate salivation rate of patients
with metal-ceramic and all-ceramic fixed dental restorations. For our
investigation were examined 86 patients: the first group included 62 patients,
which used metal-ceramic prothesis and
second group included 24 patients with
metal-free prosthesis. Also examined 15 almost
people as a control group. Each
group was subdivided into 2 subgroups :subgroup A(31 patients in first group
and 12 in second ) - the patients didnt
use preparation “Erbisol”, subgroup B(31 patients in first
group and 12 in second) – patients used the preparation.“Erbisol“ -
immunomodulator, reparant and adaptogen. For orthopedic patients of both group
of examination we produced orthopedic structures with implant-supported cement fixation : for first group produces
metal-ceramic prostheses based on cobalt-chromium alloy Duceralloy
*C, which were fixated on titanium implants. For second group produced
metal-free ceramic prostheses based on zirconium oxide and pressed ceramic IPS
Empress.
The analysis of results of
salivation rate has shown , that a 1 month after fixation of fixed restorations
on implants the change in salivation rate had statistically insignificant
character (p>0,05) relative to control.
By 2th month of observation
noticed statistically significant increase of saliva amounts in al groups, what estimated as a reaction
to orthopedic treatment.
By 3th month after
prosthetics in 1 group noticed the increase of volume of salivation:n subgroup
1A(with no using adaptogenic therapy) – it was 0,95±0,032 ml/min, that higher
than in control by 39,0%
(p<0,001).The situation in second group was different. By 3 month after
prosthetics in subgroup 2A the rate of salivation was 0,80±0,032 ml/min.,that
was by 17,6% higher than the control (p< 0,05),and in group 2B had
statistically insignificant characteristic relative to control and was
0,73±0,030 ml/min (p>0,05)
On the following dates of
investigation the indicators of salivation rate approached to the control , at
the same in 1 group of observation the
high indicators of salivation rate observed up to 4th month
after prosthetics and was the most
expressive in subgroup 1A, and it was 0,85±0,033 ml/min, that was by 25,0%
higher than the control (p<0,05)
Conclusions:
1.
During the
clinical observation estimated, that the carrying out of orthopedic treatment by implant-supported fixed restorations
has irritaion effect and leads to
inflammation of periimplantational soft tissues , as evidenced the increase of
saliva rate – by 20,95%.
2.
Estimated,
the time of adaptation to fixed metal-ceramic prothesis ,which fixated on dental implants , is 4-5
month, and all-ceramic – 3-4 month.
3.
Showed,
during the using preparation “Erbisol” in complex treatment of the
patients having implant-supported fixed restorations the
intensity of inflammatory processes decreased
by 23%, and the time of adaptation to ortopedic treatment reduces by 1-2
month, as evidenced the approximation of investigated markers to norm by 3-4
month in intergroup comparison
