Conditions

Gingival Recession Free Mucogingival Grafts Root Coverage Periodontal Plastic Surgery

Summary

The goal of this clinical trial is to to describe and evaluate an approach, free mucogingival graft (FMG), in periodontal plastic surgery for root coverage (RC) in lower incisor gingival recessions (GR) with mucogingival conditions and deformities (MCD) that might negatively influence the outcomes of conventional RC procedures.

Plain Language Summary

Simplified for easier understanding

This dental study investigates using a free mucogingival graft — tissue taken from the palate — to cover exposed root surfaces (gum recession) on lower front teeth. Gum recession is a common problem where the gum line pulls away from the tooth, exposing the root, causing sensitivity, aesthetic concerns, and increasing the risk of decay and tooth loss. The lower front teeth are particularly vulnerable due to their thin gum tissue. This study evaluates the effectiveness of this grafting technique specifically in patients with recession associated with a narrow band of attached gum tissue. Eligible patients are healthy adults with deep gum recession on lower incisors and low plaque and bleeding scores (meaning good oral hygiene). Patients who smoke 10 or more cigarettes a day, are pregnant, take medications contraindicating oral surgery, or have widespread gum recession across multiple areas are excluded. Gum recession can progress silently for years before patients notice sensitivity or aesthetic changes. Grafting procedures restore protective tissue around the tooth root, reduce sensitivity, and prevent further recession — but outcomes depend heavily on choosing the right technique for the right patient. This study's findings will help clinicians decide when this particular approach is most likely to succeed, improving long-term outcomes for patients with this very common dental condition.

Interventions

PROCEDUREBuccal muco-gingival tissue graft

Recipient Site Preparation. In the GR, a sulcular incision limited to the vestibular face will be made, which will continue until reaching the tip of the buccal papillae on each side of the GR. Two vertical incisions from the base of the two papillae to the bottom of the vestibule and one horizontal incision will connect the ends of both vertical incisions to remove the pedicle tissue. The exposed root surface will be cleaned and smoothed with mini-curettes. Donor site preparation. The incisions will be made in the same way as in the recipient area, including both papillae. The vertical incision will measure the distance from the cementoenamel junction (CEJ) to the bony dehiscence in the GR tooth, plus at least 2 mm. The tissue between the incisions will be elevated fjull or partial thickness close to the bone in the keratinized portion and superficially in the mucosal portion. A soft tissue substitute will be adapted and sutured to protect the donor site.

PROCEDUREPalatal connective tissue graft

Recipient Site Preparation. In the GR, a sulcular incision limited to the vestibular face will be made, which will continue until reaching the tip of the buccal papillae on each side of the GR. Two vertical incisions from the base of the two papillae to the bottom of the vestibule and one horizontal incision will connect the ends of both vertical incisions to remove the pedicle tissue. The exposed root surface will be cleaned and smoothed with mini-curettes. Donor site preparation A connective tissue graft will be taken from the palatal area, at the level of the premolars, which will include the two papillae. The size of the graft will be the same as that of the recipient area. A soft tissue substitute will be adapted and sutured to protect the donor site, especially if there is exposed bone.
