The stability of the alveolar-bone height and the density of the reformed bone show the success of the process. In research, bone healing is evaluated clinically and radiologically two months following tooth extraction.In analyzing alveolar bone height, geometric analysis via comparison of two roentgenograms was used. The roentgenogram before extractionwas used for measurement and calculation of the two-dimensional bonedefect following tooth extraction. On the second roentgenogram, which shows the alveolar ridge two months after tooth ex traction, the actual heightof the reformed bone was measured and compared with the height of bone failure immediately after extraction. The rate of the healing process was expressed as a percentage. The roentgenogram obtained after tooth extraction was scanned; the density of reformed bone was measured with the aid of a computer program and compared to that of the surrounding bone. The average height of bone healing was found to be 87.1%. The best healing process (97.5%)is seen in patients between 10 and 20 years; it decreases with age. Alveolar sockets with the lowest ability to heal (81.3%) were found in patients aged 61 to 70 years. The results of bone healing regarding the presence (or absence) of the surrounding teeth show the highest alveolar socket healing tendency in the presence of both surrounding teeth (97.4%), andthe lowest healing tendency in cases where the alveolar socket did not haveany surrounding teeth (82.2%). It was established that anterior maxillary teeth have the lowest bone healing tendency. The measurement of reformed bone density in healed alveolar sockets showed an average value of 82% and decreased with age with a high rate of statistical significance, the regression coefficient being 3.6 x 10-7.

Dobro zakostenevanje predstavlja čim bolj ohranjena višina alveolarne kostnine ter podobna gostota novonastale kostnine okolišnji kostnini. V raziskavi smo klinično in rentgenološko ocenili zakostenevanje zobne alveole dva meseca po puljenju. Za analizo višine zakostenevanja alveolesmo uporabili geometrijsko analizo za primerjavo dveh rentgenogramov Rentgenogram zoba pred puljenjem je omogočal merjenje in izračun dvodimenzionalne velikosti nastalega kostnega defekta po puljenju zoba. Na rentgenogramu alveolarnega grebena dva meseca po puljenju zoba smo izmerili dejansko višino novonastale alveolarne kostnine ter jo primerjali z velikostjopri puljenju nastalega kostnega defekta in zakostenevanje izrazili vodstotkih. Rentgenogram po puljenju smo skenirali in z računalniškim programom izmerili gostoto novonastale kostnine in jo primerjali z gostoto okolišnje kostnine. Povprečno zakostenevanje pri preiskovancih je bilo 87,1%. Zakostenevanje je najvišje v starosti od 10 do 20 let (97,5%) ter s starostjo upada. Najslabše zakostenevanje je pri preiskovancih, starih od 61 do 70 let (81,3%). Rezultati zakostenevanja alveole glede na prisotnost sosednjih zob kažejo najboljše zakostenevanje ob prisotnosti obeh sosednjih zob (97,4%) ter najslabše, ko alveola nima nobenega sosednjega zoba (82,2%). Glede na vrsto zob smo ugotovili najslabše zakostenevanje v interkaninem sektorju zgornje čeljustnice. Relativna gostota novonastale kostnine je v povprečju 82% in padas starostjo z visoko značilnostjo, regresijski količnik je 3,6 x 10-7. Rezultati raziskave kažejo značilnosti zakostenevanja alveole dva meseca po puljenju glede na višino in gostoto zakostenevanja.
