Abstract
Alveolar bone loss (RRR) is a continous process leading to a reduction of the morphological face height and counterclockwise rotation of the mandible. It has been speculated that both systemic and local factors contribute to RRR.
The aim of this study was to analyse the rate of RRR in five different regions of both jaws on lateral cephalograms.
The rate of RRR was analysed in five different regions of both jaws in lateral cephalograms of 50 complete denture wearers during a one year period and the contribution of some factors to the rate of RRR was also analysed. 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. Hierarchic regression analysis was made to reveal the contribution of different factors to RRR.
Hierarchic regression analysis was made (the factors included were: body, mass index, gender, age, time of edentulousness, number of previous dentures, night-time denture wearing, period od postmenopause in women, surface of denture bearing area and place of last extraction) and revealed that the only statistically significant factors contributing to RRR was the period od edentolousness and number of previous dentures (p < 0.05).
The period of edentulousness and number of previous dentures (p < 0.05) contributed significantly to the rate of RRR.
