“…During further healing, remodeling processes of soft tissue transplants and soft tissue substitutes are common and were described in previous preclinical and clinical experiments [16,20,27,28]. Moreover, it has also been observed that the tissues underlying the soft tissue grafts undergo remodeling processes as well [18].…”

“…Compared to the volume after surgery, a decrease of 15% was documented during the first three weeks (Rotenberg & Tatakis, 2014), a further decrease of 11% was recorded between 1 month and 3.5 months (Studer et al, 2000). In contrast, tissue stability was reported in a clinical study 4-6 weeks following surgery (Allen et al, 1985).…”

Objective To evaluate volumetric changes of soft tissues at pontic sites in patients treated with or without soft tissue grafting over an observation period of 10 years. Materials and Methods A total of 17 patients receiving a tooth‐borne fixed dental prosthesis (FDP) were enrolled in this study. Nine patients received a subepithelial connective tissue graft (SCTG) at the pontic site (test). Eight patients continued without soft tissue grafting (control). Baseline impressions were taken after delivery of the final FDP and at 10 years. Casts were scanned and digital images were superimposed for volumetric and linear measurements: the mean distance (MD) between the surfaces at the mid‐buccal area, the pontic height (PH) and the ridge width (RW). All comparisons were performed applying the Wilcoxon–Mann–Whitney test. Results The median follow‐up time was 123 months. Median MD between baseline and 10 years was −0.64 mm (Min: −2.39; Max: −0.02) (test) and −0.22 mm (Min: −1.07; Max: 0.06) (control). The change of PH (recession) was −0.33 mm (Min: −0.82; Max: 0.06) (test) and −0.17 mm (Min: −0.8; Max: 0.23) (control). The median differences in RW 1 mm below the crest were −0.62 mm (Min: −1.17; Max: 0.22) (test) and −0.2 mm (Min: −1.9; Max: 0.28) (control). None of the differences between the groups were significant (p > 0.05). Conclusions Limited by a retrospective study design, pontic sites with or without soft tissue augmentation by means of a SCTG underlie minimal changes over an observation period of 10 years.

“…It is indicated in partially and fully edentulous patients to increase the soft tissue volume around dental implants predominantly for esthetic reason (Kinsel and Capoferri 2008, Bichacho 1998, Price & Price 1999). In addition, autogenous soft tissue grafting procedures have also been proposed to surgically correct localized alveolar defects, as pre-prosthetic site-development, and as ridge preservation procedures (Jung et al 2004, Prato et al 2004, Seibert 1983, Studer et al 2000, Fickl et al 2009b). …”

Thoma DS, Jung RE, Schneider D, Cochran DL, Ender A, Jones AA, Görlach C, Uebersax L, Graf‐Hausner U, Hämmerle CHF. Soft tissue volume augmentation by the use of collagen‐based matrices: a volumetric analysis. J Clin Peridontol 2010; 37: 659–666. doi: 10.1111/j.1600‐051X.2010.01581.x. Abstract Objectives: The aim was to test whether or not soft tissue augmentation with a newly developed collagen matrix (CM) leads to volume gain in chronic ridge defects similar to those obtained by an autogenous subepithelial connective tissue graft (SCTG). Material and Methods: In six dogs, soft tissue volume augmentation was performed by randomly allocating three treatment modalities to chronic ridge defects (CM, SCTG, sham‐operated control). Impressions were taken before augmentation (baseline), at 28, and 84 days. The obtained casts were optically scanned and the images were digitally analysed. A defined region of interest was measured in all sites and the volume differences between the time points were calculated. Results: The mean volume differences per area between baseline and 28 days amounted to a gain of 1.6 mm (CM; SD±0.9), 1.5 mm (SCTG; ±0.1), and a loss of 0.003 mm (control; ±0.3). At 84 days, the mean volume differences per area to baseline measured a gain of 1.4 mm (CM; ±1.1), 1.4 mm (SCTG; ±0.4), and a loss of 0.3 mm (control; ±0.3). The differences between CM and SCTG were statistically significant compared with control at 28 and 84 days (p<0.001). Conclusion: Within the limits of this animal study, the CM may serve as a replacement for autogenous connective tissue.
