Anatomy and Rationale
– Oral cavity has keratinized and nonkeratinized tissue
– Keratinized tissue surrounds teeth and is called gingiva
– Alveolar mucosa is nonkeratinized oral epithelium
– Nonkeratinized tissue lines cheeks, underside of tongue, and floor of mouth
– Lips contain both non-keratinized and keratinized 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 keratinized tissue to cover tooth roots and restore firm placement within the jaw
– Prevents further damage to bone and keratinized 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 keratinized 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

– 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

Gingival grafting (Wikipedia)

Gingival grafting, also called gum grafting or periodontal plastic surgery, is a generic term for the performance of any of a number of periodontal surgical procedures in which the gum tissue is grafted. The aim may be to cover exposed root surfaces or merely to augment the band of keratinized tissue.
