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.
Study Type
OBSERVATIONAL
Enrollment
90
measurement of clinical parameters
Diagnosis of peri-implantitis (composite outcome made of different outcomes): yes or no (dichotomous)
dichotomous (yes or no) outcome composed by PPD (mm), BoP/SOP (yes or no dichotomous) and bone loss (mm, assessed on radiograph)
Time frame: Day 1
Mucosal recession
Distance (mm) between the prosthetic margin/ locator and the mucosal margin
Time frame: Day 1
Bleeding on probing (BOP)
dichotomous measure of mucosal inflammation detected via periodontal probe
Time frame: Day 1
Probing pocket depth (PPD)
distance between the mucosal margin and the bottom of the sulcus/ pocket (mm)
Time frame: Day 1
Self-assessed Brushing discomfort
Rated by patient on Visual analog score (100 mm) to define the amount of discomfort during brushing, with 0 being the minimum and 100 being maximum discomfort. The patient will be asked to rate their level of discomfort by placing an X over the line. The distance from 0 to the X will be measured and converted into a percentage of the entire length of the line.
Time frame: Day 1
Crestal bone loss (mm)
Measured on radiograph (in mm) between the implant shoulder and the most coronal location of the crestal bone
Time frame: Day 1
Suppuration on probing
measured dichotomously (yes/no) when probing an implant
Time frame: Day 1

Diagnosis of mucositis
dichotomous (yes/no) presence of mucosal peri-implant inflammation in the absence of crestal bone loss
Time frame: Day 1
