The goal of this study is to evaluate how effective a gum grafting procedure is in treating gum recession that affects several teeth. Gum recession happens when the gum tissue pulls away from the tooth, exposing the roots. The study will look at how the treatment improves gum health, appearance, and function.
A total of 32 patients will take part in the study. All patients will be treated with a modified coronally advanced tunnel. For half of them of contiguous graft will be used, for the other half a segmented graft.
Data collected will include medical history, dental and aesthetic information, clinical measurements, and a digital scan of the mouth.
The study will include the following steps:
Before the procedure: You will have a clinical and X-ray examination to determine how much your gums have receded. A digital impression of your teeth will also be taken.
Surgical procedure: You will receive a gum graft to cover the exposed roots. This involves moving gum tissue, often taken from the roof of your mouth, to the affected areas.
After the procedure: You will have several follow-up visits over a few months to check your healing and the results of the treatment.
Study timeline:
The surgery will be done once. Follow-up visits will take place 1, 3, 6, and 12 months after the surgery. The total duration of the study is about 12 months.
ASA I or ASA II
Good periodontal health
Able to undergo oral surgery
Must be 18 years old and older
Teeth showing recession associated with a carious lesion, restoration or cervical prosthesis involving CEJ
Teeth with recession depth >5mm
Molars with recessions will be treated but will not be taken into account for the measurements
Teeth with recession that have already undergone periodontal surgery
Parallel
Selective/Segmented graft
Procedure/SurgeryIn this group a segmented CTG will be used
Continuous graft
Procedure/SurgeryIn this group a continuous CTG will be used
Digital complete root coverage
defined as the presence/absence of complete coverage of the recession at the mid-buccal aspect. It will be evaluated by taking the CEJ as a reference line, at the different timepoints, analysed digitally using the digital impression
Complete Root Coverage
defined as the presence/absence of complete coverage of the recession at the mid-buccal aspect. It will be evaluated by taking the CEJ as a reference line, at the different timepoints.
Mean Root Coverage
defined as the percentage of root coverage in the mid-buccal aspect, taking baseline as a refer-ence. It equals to difference of the linear distance (in mm, using probe) between the mid-buccal point of the CEJ and the mid-buccal margin at baseline and different timepoints, divided by the distance between the mid buccal point of the CEJ and the mid buccal margin at baseline. The MRC will be measured as percentage (%).
Keratinized Tissue Height
Defined as the linear height of keratinized tissue, measured between the mid-buccal gingival mar-gin of the treated tooth and the muco-gingival junction (in mm using a probe). It will be measured at baseline and at the different timepoints.
Recession reduction
defined as the linear reduction in recession (in mm using a probe), at the mid buccal aspect, be-tween baseline and the different timepoints. It will be measured at the different timepoints.
