STUDIUL CANTITĂŢII ŞI CALITĂŢII OSULUI DISPONIBIL ÎN ZONA PREMOLARĂ MAXILARĂ.

The purpose of this study was to evaluate the available bone of the maxillary premolar area. Materials and methods. 31 patients, 10 men and 21 women, aged 40-70 years, with edentulous maxillary premolar area were selected for the study. A qualitative and quantitative analyze was performed using cone beam computed tomography (CBCT) in this patients. Results. Regarding the bone quantity, the patients were divided as follows: 26 (83.87%) had (subantral class – SA) 1, and the remaining, 5 (16.13%), had (subantral class – SA) 2. Regarding the bone quality, D3 type was found in 46 cases (74.19%), D4 type was found in 12 cases (19.35%), and D2 type was found in 4 cases (6.46%). Conclusions. Accurate analysis regarding bone resorption and atrophy can be performed only by CBCT evaluation. [ABSTRACT FROM AUTHOR]
