Sammanfattning

ObjectiveThe present investigation was performed to determine some dimensional alterations that occur in the alveolar process of the incisor and premolar sites of the maxilla following tooth removal. Material and methodsComputer-assisted cone-beam computed tomography (CBCT) scans were obtained from the maxilla using an iCAT unit, and involved edentulous and contralateral tooth sites. For each site included in the study, parasagittal and axial reconstructions, 1mm apart, were made and measurements of different variables (cross-sectional area, height, and width) performed. ResultsThe study involved 69 subjects and disclosed that the cross-sectional area and the height and width of the alveolar process of the lateral incisor site were the smallest and those of the second premolar the largest. All parameters had been significantly reduced after the completion of the 1year of healing. Thus, the overall (i) cross-sectional area was reduced from 99.1 to 65.0mm(2), (ii) the height from 11.5 to 9.5mm, and (iii) the width from 8.5 to 3.2mm (marginal 1/3(rd)), 8.9 to 4.8mm (middle portion), and 9.0 to 5.7mm (apical portion). ConclusionThe removal of single tooth caused marked hard tissue diminution. The loss of hard tissue was most pronounced in the buccal and marginal portions of the edentulous ridge that in most sites had acquired a triangular shape.
