Background/Aim. Flapless implant surgery has become very important issue
during recent years, mostly thanks to computerization of dentistry and
software planning of dental implants placements. The aim of this study was to
compare flap and flapless surgical techniques for implant placement through
radiographic and radiofrequency analyses. Methods. The experiment was made in
five domestic pigs. Nine weeks following domestic pigs teeth extraction,
implants were placed, on the right side using surgical technique flap, and
flapless on the left side. Digital dental Xrays were applied to determine
primary dental implant stability quality (ISQ). At certain intervals, not
later than three months, the experimental animals were sacrificed, and just
before it, control X-rays were applied to measure dental implants stability.
Results. Radiographic analysis showed that peri-implant bone resorption in
the first 4 weeks following placement implants with flap and flapless
surgical techniques was negligible. After the 3 months, mean value of
peri-implant bone resorption of the implants placed using flap technique was
1.86 mm, and of those placed using flapless technique was 1.13 mm. In relation
to the primary dental implant stability in the first and second week there
was an expected decrease in ISQ values, but it was less expressed in the
dental implants placed using the flapless technique. In the third week the
ISQ values were increased in the dental implants placed by using both
techniques, but the increase in flapless implant placement was higher (7.4
ISQ) than in flap implant placement (1.5 ISQ). The upward trend continued in
a 4- week period, and after 3 months the dental implant stability values in
the implants placed using flap technique were higher than the primary
stability for 7.1 ISQ, and in the implants placed using flapless technique
were higher comparing to the primary stability for 10.1 ISQ units.
Conclusion. Based on the results of radiographic and resonance frequency
analyses it can be concluded that the flapless technique in surgical implants
placemat, leads to better results.
