“…That study compared the shift of MGJ between the groups with/without primary flap closure, demonstrating 3.83 ± 2.68 and 1.21 ± 0.94 mm of shift, respectively. Despite controversy regarding keratinized mucosa around implants (Lim, Wiedemeier, Hammerle, & Thoma, ; Monje & Blasi, ; Schwarz, Derks, Monje, & Wang, ), a recent systematic review favoured the soft tissue grafting procedure for gaining keratinized mucosa in order to establish peri‐implant health (Thoma et al, ). Less change in the MGJ following ARP with the open‐healing approach may contribute to the stable mucosal situation around the implants without an additional soft tissue grafting procedure.…”

Aim To determine the effect of alveolar ridge preservation (ARP) in molar sites without primary flap closure. Materials and Methods Three groups were established: extraction sockets grafted with deproteinized bovine bone mineral containing 10% collagen (DBBM‐C) and covered by a native bilayer collagen membrane (NBCM) (test group 1), sockets grafted with DBBM‐C only (test group 2), and sockets that healed naturally (control group). Primary flap closure was not attempted. Conebeam computed tomography scans were obtained immediately and then 4 months after ARP. A biopsy was performed. The change of the marginal bone level was measured. Results There was significantly less horizontal resorption in test group 1 than in the control group at levels 1 mm (−1.02 ± 0.88 [mean ± SD] vs. −4.44 ± 3.71 mm) and 3 mm (−0.31 ± 1.51 vs. −2.27 ± 1.15 mm) below the crest, and significantly less vertical reduction in the midcrestal area in test group 1 than in test group 2 (−0.25 ± 0.95 vs. −1.15 ± 1.63 mm) (p < .05). There were no significant differences between test groups in clinical and histomorphometric measurements. All groups exhibited stable marginal bone levels after 1 year of loading. Conclusion Alveolar ridge preservation without primary flap closure in molar areas was effective in minimizing ridge resorption and facilitated implant treatment.

“…This lack of correlation may result from several factors, including tissue remodeling processes, implant type, implant orientation/position, and possible grafting procedures . Clinicians are advised to consider soft tissue grafting procedures when an undesirable implant outcome is foreseen …”

“…Recent studies have also investigated the influence of PhMT‐s to increase the amount of KTW using soft tissue grafting procedures. A systematic review by Thoma et al . concluded that PhMT may result in more favorable peri‐implant tissue health such as a gain of KTW, an improvement of bleeding indices, and a higher marginal bone levels.…”

Background This systematic review endeavored to investigate the effect of soft tissue phenotype modification therapy (PhMT‐s) at sites with a tooth or an implant supported fixed dental prosthesis. Methods A comprehensive literature search was conducted by two independent examiners to identify relevant studies reporting differences in clinical, esthetic, or radiographic outcomes of interest between sites underwent PhMT‐s and sites that remained untreated. Risk of bias assessment was calculated for all included studies. Meta‐analyses involving endpoints of interest were performed when feasible. Results No controlled studies pertaining to tooth sites were identified. A total of six articles reporting on the outcomes of buccal soft tissue phenotype modification around implants were selected, of which, five were included in the meta‐analyses. Quantitative analyses showed a weighted mean difference (WMD) of 0.98 mm (95% CI = 0.25 to 1.72 mm, P = 0.009) for change of tissue thickness; a WMD of −4.87% (95% CI = −34.27 to 24.53%, P = 0.75) for bleeding on probing (BOP); a WMD of 0.36 mm (95% CI = 0.12 to 0.59 mm, P = 0.003) for mucosal recession (MR); a WMD of 0.13 mm (95% CI = −0.11 to 0.36 mm, P = 0.30 for probing depth (PD); a WMD of 1.08 (95% CI = −0.39 to 2.55, P = 0.15) for pink esthetic score (PES), and a WMD of 0.40 mm (95% CI = −0.34 to 1.14 mm, P = 0.28) for marginal bone loss (MBL). Conclusions Surgical modification of peri‐implant soft tissue phenotype via PhMT‐s may decrease the amount of MR. Future clinical trials are needed to warrant the clinical benefits of modifying soft tissue phenotype around tooth‐supported restorations.

“…This is commonly performed in an attempt to attenuate or eliminate the effect of the shade of the abutment (e.g., titanium alloy, gold, or zirconia) on the buccal aspect of the mucosa 11–16 and/or to compensate for possible underlying bone deficiencies resulting from unfavorable osseous remodeling patterns, prior to or after functional loading 17–19 . Although the vast majority of studies conducted in this area have focused on the effect of MT augmentation for esthetic purposes, a recent systematic review reported that the performance of soft tissue grafting procedures for gain of MT resulted in significantly less interproximal marginal bone loss over time 20 . A consensus on the minimum MT required to achieve predictable long‐term functional and esthetic outcomes, and to minimize marginal bone loss and mucosal recession, has not been established 21 .…”
