Sažetak

Alveolar bone loss (RRR) is a continous process following tooth extraction, more pronounced
during the first few months after the tooth extraction than later. The RRR in
the mandible is twice that of the maxilla during a 1-year period and the mandibular:
maxillary resorption ratio increases further to 4:1. So far, the etiology of RRR has not
been elucidated. It has been speculated that both systemic and local factors contribute.
The aim of this study was to analyse the rate of RRR in five different regions of both
jaws on lateral cephalograms of 100 complete denture wearers during a one-year period
and to compare the rate of RRR between patients being edentulous over a different period
of time and between patients with different body mass index. The height of residual
ridges was measured on 5 different sites at the delivery of the dentures and a year later
using a calibrated grid. The results revealed significant RRR in a one year period. Body
mass index had no significant influence on the rate of RRR on any of the five examined
sites of the maxilla or the mandible (p>0.05), while the period of edentulousness had a
significantly higher rate of resorption in first 3 sites of measurement (anteriorly) in patients
being edentulous less than 1 year than in patients being edentulous for 1–10 years
or for over 10 years (ANOVA, p<0.05).
