The objective of this project is to evaluate 1-year outcomes of treatment of MAGRD using a modified coronally advanced tunnel technique (MCAT) with either conventional CTG (control group) or micro-CTG (test group).
age ≥18 years,
systemically healthy,
presenting with a minimum of 4 and a maximum of 6 adjacent RT1/RT2 recessions, located in the maxilla or mandible with an apico-coronal extension (i.e. recession depth) of ≥2 mm,
Full-Mouth Plaque Score (FMPS) <20%,
pregnancy or lactation,
tobacco smoking,
uncontrolled medical condition,
medication that can affect gingival conditions.
Parallel
Coronally Advanced Flap combined with a Connective Tissue Graft
Procedure/SurgeryMultiple adjacent gingival recession defects will be covered by coronally advanced flap combined with a connective tissue graft harvested from the palate.
Coronally Advanced Flap combined with micro Connective Tissue Graft
Procedure/SurgeryMultiple adjacent gingival recession defects will be covered by coronally advanced flap combined with multiple micro connective tissue graft harvested from the palate.
Division of the Connective Tissue Graft into multiple micro Connective Tissue Grafts
DeviceThe harvested connective tissue graft is divided in multiple micro connective tissue grafts with a scalpel blade before being placed on the recipient site.
Mean mid-facial recession coverage (mRC)
Percentage of the exposed tooth root covered after surgical intervention
Complete Root Coverage (CRC)
Frequency of complete root coverage
Changes of Keratinized Tissue Width (KTW)
Measured as the distance from the muco-gingival-junction to the gingival margin
Changes of Gingival Thickness (GT)
Measured 3 mm apically from the free gingival margin at the mid-buccal aspect of the tooth
Patient Morbidity
Measured with Visual Analogue Scale (VAS), which consists of a 10cm line, with two end points representing 0 ('no pain') and 10 ('pain as bad as it could possibly be')
