The expanded mesh free gingival graft: A novel approach to increase the width of keratinized mucosa

A modified geometric technique to increase peri-implant keratinized mucosa

OBJECTIVE

The free gingival graft (FGG) has been identified as the most effective method for increasing keratinized mucosa width (KMW). However, the challenge emerges in cases of extensive keratinized mucosa deficiency, where efficient utilization of the patient's limited keratinized tissue to achieve optimal results is crucial. This article introduces a modified geometric technique to address this clinical issue.

CLINICAL CONSIDERATIONS

Utilizing geometric principles, the modified technique involves dividing the rectangular graft into two triangular or trapezoidal sections, which are then reassembled to form an approximate diamond shape. Through strategic cut and splice, the graft is reshaped to suit the recipient site.

CONCLUSION

Preliminary observations in cases employing the modified geometric technique have increased the KMW around implants. This method enhances graft utilization and offers a viable clinical option for surgical plans aimed at widening keratinized mucosa in instances of large-area KMW deficiency.

CLINICAL SIGNIFICANCE

This article proposed a modified method to increase KMW, which may be an optimal choice for patients with insufficient KMW in large area, avoiding the waste of limited graft, decreasing patient morbidity, and effectively widening keratinized mucosa.

Modifications in the Free Gingival Graft Technique: A Systematic Review

Free gingival grafts (FGGs) have developed beyond covering exposed roots to improve the width and thickness of gingival tissue. While traditional FGGs have shown a high success rate and are easy to apply, they have some drawbacks, such as potential aesthetic concerns and bulky appearance. Recent advancements in FGGs have been explored, with different modifications proposed to overcome these limitations, including partly epithelialized FGGs (PE-FGG), gingival unit grafts, and epithelialized subepithelial connective tissue grafts. This systematic review aims to evaluate published case reports that discuss the utilization of modified approaches to FGG treatment and their outcome.
