Hong HR, et al. - A sum of 30 candidates were examined to analyze the influence of two different ridge preservation techniques on soft and hard tissue dimensions. Candidates wanting tooth extraction were randomly allotted to either control group C ie, allograft covered with a non-crosslinked collagen membrane with primary closure or experimental group E ie, allograft covered with cross-linked collagen membrane left exposed. An increase of 0.43 ± 0.42 mm in the width of the buccal keratinized tissue in the E group when compared to net loss of 1.57 ± 0.51 mm for the C was noted. A slight reduction (68.3 ± 17 mm3) in the volumetric assessment of the changes in the alveolar ridge for the E group was reported whereas the C group encountered almost double this loss (107.5 ± 11 mm3). They recorded a significant reduction in crestal width (measured on the CBCT scan) in the C group (4.18 ± 0.56 mm) vs 1.74 ± 0.4 mm in the E group. Better preservation of keratinized tissues (width and thickness) with comparable and at times greater osseous preservation was succeeded in crosslinked collagen membrane with allograft placed intentionally non-submerged following extraction.
