“…The positive association between KM and VD is of key importance, since it implies that a shallow VD could interfere with proper oral hygiene techniques, thus leading to more plaque accumulation. This finding is in agreement with a previous clinical study reporting the association between VD and a lack of KM, and also increased bone loss and mucosal recession around implants and natural dentition …”

Background Given the fact that most patients are not regular compliers in supportive peri‐implant maintenance programs, it is of interest to examine the significance of the peri‐implant soft tissue characteristics in relationship to the onset of peri‐implant diseases. Methods Based on an a priori statistical power calculation, a cross‐sectional study was conducted on erratic peri‐implant maintenance compliers (<2 times/year) to examine the significance of keratinized mucosa (KM) and gingival tissue (KT) on peri‐implant and adjacent periodontal conditions in implants restored ≥3 years. Seven clinical parameters were recorded around implants and the adjacent buccal sites. Radiographic assessment was performed using periapical X‐rays. In addition, a visual analog scale (VAS) was used to evaluate the impact of KM upon brushing comfort. The case definition used for peri‐implant diseases was in accordance with the 2017 World Workshop on the classification of periodontal and peri‐implant diseases and conditions. Results Overall, 37 patients with 45 edentulous gaps restored with 66 implants and 90 adjacent teeth were analyzed. On comparing a KM band of <2 mm versus ≥2 mm, with the exception of suppuration (P = 0.6), all the clinical and radiographic parameters were significantly increased when the KM band was <2 mm (P < 0.001). A significant correlation was observed between KM and KT (r = 0.55), though a lack of KM did not condition a lack of KT. In the presence of peri‐implantitis, only bleeding on probing at the adjacent dentate sites was identified to be increased. Conclusions The presence of <2 mm of KM around dental implants in erratic maintenance compliers seems to be associated with peri‐implant diseases. The lack of KM constitutes a site‐specific phenomenon independent of the keratinized tissue present in the adjacent dentition (NCT03501537).

“…Considering that sites with subgingival restorations showed higher probing depth and clinical attachment loss compared to healthy sites, it could expect that in some years a higher occurrence of disease may also be observed in these sites. Although several studies have investigated the effect of proximal restorations on the periodontal tissue (Ababnaeh, Al‐Omari, & Alawneh, ; Albandar, Buischi, & Axelsson, ; Broadbent, Williams, Thomson, & Williams, ; Halperin‐Sternfeld, Saminsky, Machtei, & Horwitz, ; Santos et al., ), this interaction is still not well established. A study in the same population at 24 years showed an association between the presence of proximal restorations and the occurrence of bleeding and dental calculus; however, the association with periodontal pocket was not observed (Demarco et al., ).…”

“…Alveolar bone resorption following tooth extraction can contribute to a reduction in vestibular depth . Shallow vestibules (≤4 mm) were associated with increased recession, greater attachment level and bleeding on probing as well as decreased keratinized tissue width around implants . Hence, its effect on keratinized tissue and vestibular depth can have a significant effect on esthetics, hygiene maintenance, and functionality of the final prosthesis.…”

Background The effect of different surgical techniques for ridge preservation on soft tissue parameters has seldom been investigated. The objective of this study was to compare the effect of two different ridge preservation techniques on soft and hard tissue dimensions. Methods Thirty patients requiring tooth extraction were randomly allocated to either control group C (allograft covered with a non‐crosslinked collagen membrane with primary closure) or experimental group E (allograft covered with cross‐linked collagen membrane left exposed). Sites were surgically re‐entered at 6 months. Soft and hard tissue measurements, cone beam computed tomography (CBCT), and cast measurements were taken at baseline and 6 months. Results Twenty‐eight patients were included in this analysis. When the two treatment groups were compared, the width of the buccal keratinized tissue in the E group showed an increase of 0.43 ± 0.42 mm compared to net loss of 1.57 ± 0.51 mm for the C (P = 0.006). Similarly, buccal tissue thickness has increased in the E group 0.46 ± 0.22 mm compared to a loss of 0.15 ± 0.23 mm in the C group (P = 0.068). Volumetric assessment of the changes in the alveolar ridge for the E group showed a slight decrease (68.3 ± 17 mm3) whereas the C group has experienced almost double this loss (107.5 ± 11 mm3; P = 0.07). Crestal width, measured on the CBCT scan, has shown significant reduction in the C group (4.18 ± 0.56 mm) compared to only 1.74 ± 0.4 mm in the E group (P = 0.003). Conclusion Crosslinked collagen membrane with allograft placed intentionally non‐submerged resulted in better preservation of the keratinized tissues (width and thickness) with similar and at times better osseous preservation following extraction.

The association between shallow vestibular depth and peri‐implant parameters: a retrospective 6 years longitudinal study

Abstract: Based on this study, inadequate vestibular depth around dental implants may be associated with increased peri-implant bone loss and mucosal recession. Further prospective and intervention studies will be required to fully understand this phenomenon.
