Abstract
The aim of this study was to screen patients with fixed prosthodontic appliances that
were in oral cavity for a period of 5 years or more and to assess clinically and radiologically
root caries, gingival recession, pocket formation, alveolar ridge resorption, as well
as gingival (GI) and plaque index (PI). The aim also was to find out the differences between
materials and constructions, between abutment and non-abutment teeth, and to
find out the need for replacement. A total of 260 patients and their orthopantomograms
were examined, with a total of 2,265 teeth, 610 being bridge abutments and 246 being
crowns. The most frequent were metal+ acrylic veneer crowns or bridges. Root caries
was found under the abutments in 10–20%; however abutments with ceramic crowns
had the lowest percentage of caries (p<0.01). Alveolar ridge resorption, pocket formation
deeper than 3 mm and gingival recession of various degree was found in 50% of the
cases, again with the lowest percentage of ceramic-fused-to-metal appliances (p<0.01).
Pocket depth was registered in significantly higher percentage in metal-acrylic veneer
appliances compared to natural teeth (p<0.01), while there was no significant difference
between metal-ceramic appliances and natural teeth (p>0.05). Although the worst findings
were recorded for metal-+acrylic veneer crowns for PI, no significant difference existed
between crowns of different material or non-abutment teeth (p>0.05). There was
statistically significant difference between abutments with metal + acrylic veneer crowns,
full metal crowns, metal ceramic crowns and non-abutments for GI scores. Higher percentage
of scores 0 and 1 was recorded for metal ceramic crowns and non-abutments
and significantly higher percentage of scores 2 and 3 was recorded for metal + acrylic
veneer crowns and full metallic crowns. Almost 50% of metal-ceramic abutments had no
pathologic findings. Almost 30% of the patients needed replacement, or even some abutments
to be extracted and therefore a new prosthodontic appliance.
