Conditions
Outcome Measures
Primary Outcomes (8)
Bleeding On Probing Index (BOP):
BOP was regarded as an indicator of inflammation of the periodontal and peri-implant tissues. Gentle probing of the orifice of the gingival crevice. If bleeding occurs within 10 seconds a positive finding is recorded.
at baseline, after 6 months, and after 12 months.
Peri- implant mucosal tissue index (MTI):
This index was proposed as part of the Toronto study in light of the significance of mucosal inflammation on peri-implant conditions during monitoring. It is based on the appearance, consistency, and texture of the peri- implant mucosa. The scores are listed below: Score 0: Normal mucosa. Score 1: Mild inflammation with slight color change and edema. Score 2: Moderate inflammation with redness, edema, and glazing. Score 3: Severe inflammation, redness, edema, and ulceration.
at baseline, after 6 months, and after 12 months.
Jemt papilla index:
Index 0: No interproximal papilla is present. Index 1: Less than half of the height of the papilla is present (less than half of the distance between the imaginary cervical line and the interdental contact point). Index 2: At least half of the height of the papilla is present (half or more than half of the distance between the imaginary cervical line and the interdental contact point, however without filling up all interdental space). Index 3: The papilla is present and fills up the entire interdental space. Index 4: The gingival papilla is hyperplastic and covers part of the crown of the adjacent tooth or denture.
at baseline, after 6 months, and after 12 months.
Probing Pocket Depth (PPD)
The distance recorded in mm from the mucosal margin to the base of the pocket. According to the peri- implant condition, the PPD is often deeper (≥6 mm) in disease or shallower (\< 6 mm) in health. It should be emphasized, however, that deep PPD may be identified in the absence of disease in scenarios exhibiting thick crestal mucosa.
at baseline, after 6 months, and after 12 months.
Modified plaque index (mPI):
Score 0: No plaque. Score 1: Plaque disclosed by running a probe around the smooth marginal surface. Score 2: Plaque can be seen by the naked eye. Score 3: Abundance of soft matter.
at baseline, after 6 months, and after 12 months.
Mucosal recession (MR)
The distance in mm from the implant- abutment connection as a steady mark and the mucosal margin. If the mucosal margin exceeds coronally the implant- abutment connection due to swelling, the MR is positive , while if it is due to implant malposition or loss of support, the margin is apical to the implant- abutment connection and the value is negative.
at baseline, after 6 months, and after 12 months.
Keratinized mucosa (KM)
The distance measured from the free mucosal margin to the mucogingival junction at the buccal position line angles and recorded to the nearest mm. Arbitrarily, a 2 mm height was set as a threshold to define sufficient/presence or insufficient/lack.
at baseline, after 6 months, and after 12 months.
Gingival thickness Measurement
Before transgingival measurements, a xylocaine spray (10% lidocaine) is applied topically to reduce pain. It is measured by transgingival method from the buccal region using a #20 endodontic file (20 K-files). The measurement is made by transgingival method after determining the point corresponding to the base of the gingival sulcus with a periodontal probe. Then, the transgingival method measurement is made 1 mm apical to this point. An endodontic file with an attached plastic stopper was inserted perpendicularly into the gingiva until it reached the tooth or the bone. The distance between the stopper and the tip of the caliper is measured using a periodontal probe or digital caliper.
at baseline, after 6 months, and after 12 months.
