Development of new technology in periodontal tissue engineering

The loss of periodontal support tissues might cause movement or finally loss of the teeth affected, impair furthermore the pronunciation and mastication functions, and even result in a series of physiological and psychological problems. Tissue engineering, as a technology to remodel missing tissues or organs and functional reconstruction, has achieved gratifying progress in regeneration of periodontal tissues. However, conventional construction methods have some deficiencies for functional periodontal reconstruction. In recent years, with the progress of tissue engineering technology, a series of new techniques and methods, such as cell sheet technology, decellular technology, electrospinning technology and three-dimensional printing, has been applied in tissue engineering bringing new hope for the regeneration of periodontal tissues. In this review article, the recent progress achieved in the field of periodontal tissue engineering and application of modern technology are summarized to make a brief exposition and to explore the future development of periodontal regeneration.
