Abstract
Statement of problem
One of the most frequent complications in participants with fixed partial dentures
(FPDs) is the apical migration of the gingival margin, which may be associated with
factors such as fit, gingival margin location, or tooth preparation type. The prevalence
of the complication in participants restored with FPDs prepared by using the biologically
oriented preparation technique (BOPT) is unclear.
Purpose
The purpose of this prospective clinical trial was to evaluate the clinical and biologic outcomes
of FPDs on teeth prepared by using the BOPT, over a 6-year follow-up period.
Material and methods
Tooth-supported zirconia FPDs in the anterior region prepared by using the BOPT were
evaluated. Each participant was monitored annually for 6 years by evaluating plaque
index, probing depth, vestibular gingival thickness, and gingival margin stability.
Biologic and/or mechanical complications were also recorded. Patient satisfaction
was measured by using a visual analog scale (VAS).
Results
A total of 25 FPDs supported by 70 teeth in 24 participants were analyzed. Low plaque
index values and stable probing depths were observed, whereas the gingival index was
0 for most of the teeth. Teeth treated by using the BOPT presented significant increase
in gingival thickness, and the gingival margin was found to be stable in 100% of the
treatments. FPD survival was 100%.
Conclusion
Tooth supporting FPDs prepared by using the BOPT presented good periodontal health
and gingival margin stability, without recession and with a 100% survival rate during
a 6-year follow-up.
