Guided bone and tissue regeneration remains an integral treatment modality to regenerate bone surrounding teeth and dental implants. Barrier membranes have been developed and produced commercially to allow space for bone regeneration and prevent the migration of unwanted cells. Ideal membrane properties, including biocompatibility, sufficient structural integrity and suitable shelf life with easy clinical application, are important to ensure good clinical regenerative outcomes. Membranes have various types, and their clinical application depends on the origin, material, structure and properties. This narrative review aims to describe the currently available barrier membranes in terms of history, main features, types, indication and clinical application and classify them into various groups. Various membranes, including those which are resorbable and non-resorbable, synthetic, added with growth factors and composed of modern materials, such as high-grade polymer (Polyetheretherketone), are explored in this review.

This is a clinical case describing a hypertensive female patient with a drug-influenced gingival enlargement (DIGE) on the labial and lingual gingivae of the lower anterior dentition. DIGE is attributed to the prolonged use of medications in a susceptible individual. She had undergone non-surgical periodontal therapy prior to surgical intervention for the removal of gingival enlargement (GE) using diode laser therapy. A diode laser is a type of laser widely used in dentistry. This laser therapy is a less invasive technique for the removal of GE. After 6 months of follow-up, no recurrence of GE was observed, and regular supportive periodontal therapy was adopted to sustain the gingival health. The utilization of the diode laser showed excellent predictability and clinical outcomes.
