The width of the attached gingiva—Much ado about nothing?

The Effect of Keratinized Mucosa Width on Peri‐Implant Outcome under Supportive Postimplant Therapy

“…Regarding peri‐implant mucositis rates (positive BoP scores), some studies have revealed significantly higher mucositis rates around implants encircled with a KM width ≤2 mm . Other studies could not confirm this correlation . The overall mucositis rate in our study was 38.19%.…”

Evaluation of Interdental Spaces of the Mandibular Posterior Area for Orthodontic Mini-Implants with Cone-Beam Computed Tomography

“…Sample size was calculated using Altman's nomogram with consideration of alpha error of 0.05 and power of 80% [22], so 40 CBCT images (with 40 quadrants without tooth extraction) of a private Oral and Maxillofacial Radiology Center's archive were taken from January to June 2011 and included in the study. Ethical clearance was obtained from Ethical Council of University for this study.…”

Necessity of Keratinized Tissues for Dental Implants: A Clinical, Immunological, and Radiographic Study

“…Although controversies exist in the literature based on the results of the studies performed, it has been reported that wide KT band takes role in formation of a resistant barrier against mechanical trauma during oral hygiene procedures especially in patients with severe bone and soft tissue atrophies and helps in formation of peri‐implant tissues in which nonkeratinized epithelium may become ineffective. In addition, it has been reported that adequate KTW prevents tissue prolapses during the intervals between prosthetic procedures and by preserving the junctional epithelium during functional movements of the mucosa, precludes mucogingival stress, which aids in maintenance of peri‐implant tissue health …”

“…In addition, it has been reported that adequate KTW prevents tissue prolapses during the intervals between prosthetic procedures and by preserving the junctional epithelium during functional movements of the mucosa, precludes mucogingival stress, which aids in maintenance of peri-implant tissue health. 25,26 Based on these knowledge, the purposes of this longitudinal study were the following: (1) to evaluate the effects of KTW on peri-implant tissue health by clinical, immunological, and radiological parameters; (2) to compare the results of two treatment strategies [maintenance/free gingival grafts (FGGs) + maintenance] for peri-implant sites with inadequate KTW; and (3) to determine the optimal treatment and maintenance procedures for peri-implant sites with inadequate KTW.…”
