Abstract
The aim of the study was to assess the rate of mandibular residual ridge resorption
in edentulous patients and to analyse the factors which determine this process.
A group of 35 edentulous patients aged between 51 and 89 years, with
a mean age of 74 (65-78) years, were included in the study. Individual factors
(age, gender and duration of edentulousness), local biochemical parameters (oral
hygiene and history of periodontal diseases) and systemic biochemical parameters
(calcium and phosphate metabolism, diet, smoking, alcohol intake and systemic
diseases), as well as physical factors involved in the process (the use of
prosthetic dentures), were analysed. The study was performed on the basis of
the results of dental examinations, assessment of panoramic radiograms, research
surveys and total calcium and phosphate serum levels, which were determined
using a calorimetric method. Bone resorption in the mandible affected all
the study patients to varying extents. More than half the edentulous patients
showed a high degree of mandibular residual ridge resorption. The duration of
mandibular edentulism was found to be closely associated with values of the
radiological IC/IM index, which is generally considered to reflect the degree of
mandibular resorption. Total calcium serum levels were shown to correlate positively
with the value of IC/IM index in these patients.
