Anatomy and Rationale - Oral cavity has keratinised and nonkeratinised tissue - Keratinised tissue surrounds teeth and is called gingiva - Alveolar mucosa is nonkeratinised oral epithelium - Nonkeratinised tissue lines cheeks, underside of tongue, and floor of mouth - Lips contain both non-keratinised and keratinised tissue - Gum grafting is a surgical procedure to reverse gum recession - Gum recession exposes tooth roots, leading to sensitivity and increased risk of damage or disease - Gum graft aims to extend keratinised tissue to cover tooth roots and restore firm placement within the jaw - Prevents further damage to bone and keratinised tissue around the teeth - Helps prevent tooth loss and maintain oral health

Options in Gum Grafting - Traditional gum grafting harvests gums from the roof of the mouth - Allografting techniques use tissue from cadavers for larger cases - Considerations include limited quantity, morbidity, and risk of disease transmission - Various grafting techniques available, such as autograft, allograft, xenograft, or repositioning of native tissue - Benefits include decreased sensitivity and increased keratinised tissue

Advantages of APRF in Gum Grafting - APRF (autologous platelet-rich fibrin) uses blood-derived growth factors for tissue regeneration - Widely used in dentistry and oral surgery - Advantages include unlimited amount of harvested blood, no risk of rejection or disease transmission, and high-quality healing - Contains autogenous growth factors and stem cells - Promotes gum fabrication and eliminates the need for other grafting techniques

Technique - Small amount of blood is harvested and spun in a centrifuge - Fibrin clot with growth factors, extracellular matrix, and stem cells is fabricated - Clot is implanted into the gums above the area of gum recession - Platelet-rich fibrin promotes gum growth and eliminates the need for other grafting sources - Enhanced healing factors lead to improved recovery and reduced recovery time

Techniques for Guided Bone Reconstruction - Grafting techniques enhance bone growth by preventing soft tissue ingrowth - Resorbable and nonresorbable membranes are used in guided bone reconstruction - Metallic membranes and membranes supported by a titanium frame have been successful - The acellular dermal matrix has been used as a barrier membrane with bone allograft - Micro-surgical procedures have made these techniques more predictable and comfortable for patients
