Implant stability and marginal bone level of microgrooved zirconia dental implants: A 3-month experimental study on dogs
Background/Aim. The modification of implant surfaces could affect mechanical implant stability as well as dynamics and quality of peri-implant bone healing. The aim of this 3-month experimental study in dogs was to investigate implant stability, marginal bone levels and bone tissue response...

| description | Background/Aim. The modification of implant surfaces could affect mechanical
implant stability as well as dynamics and quality of peri-implant bone
healing. The aim of this 3-month experimental study in dogs was to
investigate implant stability, marginal bone levels and bone tissue response
to zirconia dental implants with two laser-micro-grooved intraosseous
surfaces in comparison with nongrooved sandblasted zirconia and sandblasted,
high-temperature etched titanium implants. Methods. Implant surface
characterization was performed using optical interferometric profilometry and
energy dispersive X-ray spectroscopy. A total of 96 implants (4 mm in
diameter and 10 mm in length) were inserted randomly in both sides of the
lower jaw of 12 Fox Hound dogs divided into groups of 24 each: the control
(titanium), the group A (sandblasted zirconia), the group B (sandblasted
zirconia plus microgrooved neck) and the group C (sandblasted zirconia plus
all microgrooved). All the implants were immediately loaded. Insertion
torque, periotest values, radiographic crestal bone level and removal torque
were recorded during the 3-month follow-up. Qualitative scanning electon
micro-scope (SEM) analysis of the bone-implant interfaces of each group was
performed. Results. Insertion torque values were higher in the group C and
control implants (p < 0.05). Perio-test values increased in all the periods
in proportion to the ex-tent of microgrooving as follows: the group C > the
control > the group B > the group A (p < 0.05). Radiographic measurements
showed minimal crestal bone loss at 3 months for microgrooved zirconia
implants (groups C and B) and control implants compared with the group A
implants (p < 0.05). The removal torque values increased with time for all
the groups as follows: the group C > the control > the group B > the group A
(p < 0.05). SEM showed that implant surfaces of the groups B and C had an
extra bone growth inside the microgrooves that corresponded to the shape and
direction of the microgrooves. Conclusion. The addition of micro-grooves to
the entire intraosseous surface of zirconia dental implants enhances primary
and secondary implant stability, promotes bone tissue ingrowth and preserves
crestal bone levels. |
