Considerable effort has been directed towards replacing lost teeth using tissue-engineering methods such as titanium implants. A number of studies have tried to modify bioinert titanium surfaces by coating them with functionally bioactive molecules for faster and stronger osseointegration than pure titanium surfaces. A bone morphogenetic protein is known to be an osteoinductive molecule to promote local bone formation. Recently, peptides have been recognized as valuable scientific tools in the field of tissue engineering. A laminin-derived functional peptide, the DLTIDDSYWYRI motif, has been evaluated for bone cell adhesion and in vivo effects on osseointegration. Many findings indicate that such a protein or peptide may act as an effective osseointegration accelerator. This presentation contains author's studies showing the results of active responses at bone-implant interfaces.
