The human body is composed of four basic kinds of tissue: nervous, muscular, epithelial, and connective tissue. Connective tissue is the most abundant type and serves as a connecting link for binding, supporting and strengthening all other body tissues. In this compilation, the authors explore connective tissue grafts, a promising and reliable method that provides a satisfactory esthetic outcome, making it a popular option for clinicians. The fundamentals of subepithelial connective tissue grafts, harvesting techniques, clinical success and possible postoperative complications is also discussed.
