Resumo
Background: The importance of primary stability in implant
placement for long-term success is well known in the literature.
The resonance frequency analysis technique has extensively
been used in experimental and clinical research for the last 10
years, for assessing primary stability. The benefits of low-level
laser therapy in bone tissue are already consolidated in the
literature, however, little is known about its benefits on improvement
of stability of dental implants.
Aim: The aim of this randomdouble blind clinical study was to
investigate whether stability of titanium implants can be enhanced
by low-level laser therapy during the osseointegration
process when measured by means of resonance frequency
analysis. Methods: Thirty implants (n¼30) were placed in the posterior
region of partially edentulous mandible of eight adult patients,
after following several inclusion criteria and were distributed
bilaterally in agreement with the prosthetic requirement. The
implants on the experimental side were randomly submitted to
low-level laser therapy (830 nm, 86mW, 92.1 J/cm2, 2.57 J, 3 s/
point, at 20 points), and on the control side the laser irradiation
was only simulated. The first irradiation was performed in the
immediate postoperative period, and it was repeated every 48 h
in the first 14 days. The initial implant stability quotient of the
implants was measured by means of resonance frequency analyzer
(Osstells). New implant stability quotient measurements
were made after 10 days, 3, 6, 9 and 12 weeks. ANOVA for
repeated measurements and Bonferroni test were used to assess
statistically significant differences. Results: The initial implant stability quotient values ranged
from 65 to 84, with a mean of 76. The irradiated side showed
significant drop in stability from the 10th day until the sixth
week only (P¼0.028), and presenting a gradual increase from
the sixth to the 12th week. In the control side, the mean implant
stability quotient increased up to the third week, decreased in
the sixth week, and then began to grow again. The highest
stability values were observed in the 10th day in the irradiated
group, and the lowest in the sixth week in both groups. No
statistical differences were detected among the ISQ means in
the two groups for each of the six times observation.
Conclusions and clinical implications: No evidence was found of
any effect of low-level laser therapy on implants’ stability when
measured by resonance frequency analysis. Because high primary
stability and good bone quality are of major relevancy for a
rigid bone–implant interface, additional low-level laser therapy under these conditions may have little impact macroscopically.
Further researches under different bone conditions are necessary
for a better understanding of the occurrences at bone/implant
interface.
