The Use of a Xenogeneic Collagen Matrix at the Time of Implant Placement to Increase the Volume of Buccal Soft Tissue

Xenogeneic collagen matrix versus connective tissue graft for buccal soft tissue augmentation at implant site. A randomized, controlled clinical trial

“…In the present RCT, both procedures resulted in a significant improvement of soft tissue thickness compared with baseline (1.2 mm for CTG and 0.9 mm for XCM); interestingly, 79% of XCM‐treated sites and 93% of CTG‐treated sites achieved final soft tissue thickness ≥2.5 mm. The magnitude of thickness increase was similar for that obtained with CTG (Wiesner et al., ) or XCM (Froum et al., ) in pilot studies testing soft tissue increase at implant site. Furthermore, in another pilot RCT, a similar effect in soft tissue augmentation was described comparing CTG to a stable collagen matrix prototype (Thoma et al., ).…”

The influence of different soft‐tissue grafting procedures at single implant placement on esthetics: A randomized controlled trial

“…21 The interpretation of their results, however, is limited by the retrospective study design and a small sample size. Froum et al, 33 evaluated the effect of a XCM in a randomized controlled clinical trial compared to no soft-tissue graft and reported an outcome comparable to ours regarding the change in height and thickness of the periimplant soft tissue. However, that study has limitations.…”

“…As far as we know, Froum et al . is the only study comparing the effect of applying a XCM with no soft tissue graft during implant placement.…”

“…In terms of recession reduction using a coronally advanced flap with either a CTG or XCM, both achieved comparable and stable results. 31,32 As far as we know, Froum et al 33 is the only study comparing the effect of applying a XCM with no soft tissue graft during implant placement. They found no differences between the groups, but intragroup comparisons revealed that, compared to baseline levels, patients receiving the XCM showed a significant thickening of the buccal keratinized tissue.…”

A 3-Year Prospective Study on a Porcine-Derived Acellular Collagen Matrix to Re-Establish Convexity at the Buccal Aspect of Single Implants in the Molar Area: A Volumetric Analysis

“…Several clinical studies have been published on alternative collagen matrices for peri-implant soft tissue augmentation. Four studies were found on Mucograft ® (Geistlich Pharma AG, Wolhusen, Switzerland) assessing soft tissue thickness changes by transmucosal probing [44][45][46] or ultrasound [39]. The mean increase in buccal soft tissue thickness in these studies ranged from 0.70 mm to 1.16 mm after 3 to 12 months of follow-up.…”
