In this article, we introduce some of the more extensively evaluated techno
logies using concepts of tissue engineering. We report on hard tissue engin
eering and soft tissue engineering and their utility for dental implant the
rapy. For hard tissue engineering, we evaluated human recombinant bone morp
hogenetic protein-2 and marrow mesenchymal stem cells using st model of sin
us augmentation procedure in rabbit. We also describe distraction osteogene
sis as another category for hard tissue engineering. In addition, we evalua
te soft tissue management using cultured epithelial grafting for soft tissu
e engineering. The results of our tissue regeneration materials and methods
in this study are positive. When the tissue engineering materials are used
in clinics in the future, implant surgery could be the leading field.
