Mr Manolis Heliotis has been involved in researching tissue engineering techniques together with other colleagues in the international arena for many years. This background has allowed him to translate laboratory research into surgical practice, carrying out pioneering work in bone regeneration in patients. The bone grafting techniques that he uses for dental implant work, sinus lifts, periodontal structures and reconstruction of jaws, trauma and orthognathic surgery are therefore founded on the solid scientific knowledge that he has helped develop, as attested by the scientific peer-reviewed publications listed below. He has presented talks in many international medical and scientific conferences on tissue regeneration.
