Partial-thickness/Non-advanced vs. Full-thickness/MCAT Tunnelling for the Treatment of Multiple Gingival Recessions
Partial-thickness/Non-advanced vs. Full-thickness/MCAT Tunnelling for the Treatment of Multiple Gingival Recessions: a Multi-centre Randomized Clinical Trial
Universidad Complutense de Madrid
34 participants
Jan 5, 2023
INTERVENTIONAL
Conditions
Summary
Included patients will be randomly allocated to the test (split-thickness non-advanced tunnel - Zabalegui et al. 1999) or to the control group (full-thickness coronally-advanced tunnel - MCAT - Aroca et al. 2010).
Eligibility
Inclusion Criteria2
- Any patient having a minimum of two adjacent teeth with RT1 and/or RT2 gingival recessions (at least one with a depth >2 mm) with indication for root coverage treatment, being at least 18 years old and able and agreeing to sign a written informed consent form will be potentially eligible for this trial. RT2 gingival recessions will be considered not eligible when associated with interproximal exposure of the CEJ (interdental gingival recession).
- In case of multiple RT1/RT2 recessions involving 2 or 3 teeth, at least 2 or 1 more non-included adjacent teeth should respectively be present in order to guarantee a minimum of 4 adjacent teeth (including the included ones) in the region of interest (ROI) for digital scanning.
Exclusion Criteria12
- Compromised general health which contraindicates the study procedures (ASA IV-VI patients);
- Systemic diseases/medications which could influence the outcome of the therapy (e.g., uncontrolled diabetes mellitus);
- Current smokers (self-reported, any type of smoking), users of chewing tobacco, and drug/alcohol abusers;
- Pregnant or nursing women;
- History of previous periodontal surgery (mucogingival or other) on the teeth to be included;
- Patients having had surgical soft tissue augmentation procedures in the ROI within the previous 12 months;
- Furcation involvement in the teeth to be included;
- Presence of severe tooth malposition, rotation or clinically significant super-eruption in the teeth to be treated;
- Presence of fixed or removable prosthesis in the area to be treated;
- Presence of RT3 gingival recessions in the same surgical area of the treatment.
- Not able to achieve good oral hygiene and control gingivitis in the whole of the dentition (FMPS < 20% and FMBS < 20%);
- Persistence of uncorrected gingival trauma from toothbrushing.

Interventions
A split-thickness non-advanced tunnel will be performed according to Zabalegui et al. (1999).
A full-thickness coronally-advanced tunnel (Modified Coronally Advanced Tunnel - MCAT) will be performed according to Aroca et al. (2010).
