Lingual Keratinized Tissue in Fully Edentulous Patients and Its Impact on Implant Health

Lingual Keratinized Tissue in Fully Edentulous Patients and Its Impact on Implant Health

Cross-sectional study involving the measurement of the width of lingual keratinized tissue (in the implant locations) in fully edentulous patients restored with dental implants. The width of KT will be correlated with the primary outcome, diagnosis of peri-implantitis, defined as Probing depth (PPD)>= 6 mm, inflammation/ bleeding on probing (BOP) and bone loss >= 3 mm from the implant platform.

The study will be conducted with a cross-sectional design. All clinical parameters (width of buccal and lingual keratinized tissue, probing depth, bleeding on probing, plaque, crestal bone loss, gingival index, suppuration) will be collected in mandibular implants in fully edentulous lower arches. The width of lingual band of keratinized tissue (KT) will be be correlated with diagnosis of peri-implantitis or peri-implant mucositis.

• Full-arch implant-supported prostheses
• Removable full-arch prostheses
• Fixed full-arch prostheses

Exclusion Criteria:

• Implants loaded less than 12 months before examination
• Mobile (non integrated) implants
• Partially edentulous patients
