Influence of defect location on absolute and relative bone gain: anterior vs left posterior vs right posterior
ОглавлениеIn the maxilla, there were 12 anterior, 11 right posterior, and 6 left posterior defects. The mean vertical deficiency was 5.5 ± 2.9 mm on the right posterior side and 4.3 ± 0.8 on the left posterior side. There were no differences in absolute bone gain between maxillary left and right posterior sides per multiple linear regression (P = 0.726). Maxillary anterior defects showed less bone gain compared with left and right posterior defects (P = 0.05) (see Table 2-4 and Fig 2-3a).
In the mandible, there were 4 anterior, 15 right posterior, and 17 left posterior defects. The mean vertical defect size was 5.8 ± 3.2 mm on the right posterior side and 5.5 ± 2.6 on the left posterior side, with no significant differences between the sides (P = 0.72). A statistically significant difference in vertical bone gain was detected between the mandibular anterior, left posterior, and right posterior areas (P = 0.028) (see Table 2-4 and Fig 2-3b). The relative vertical gain was 98.3% for mandibular left posterior sites and 90.9% for right posterior sites (0.3 mm of absolute gain difference).
