Figure 45. Radiographic height reduction
The mean crestal height change as assessed on the radiographs was 1.53 mm.
Figure 44. Mean height reduction
The mean reduction in height was approximately 1.7 mm.
Figure 43. Mean width reduction
The weighted means showed that the clinical loss in width is greater than the loss in height. The mean reduction in width of the alveolar ridge was calculated to be approximately 4 mm.
Figure 42. Dimensional change in alveolar bone
A recent systematic review evaluated the amount of change in height and width of the residual ridge after tooth extraction.
