The aim of the lecture is the presentation of the results of the investigations of the new obtained biological-engineering composite materials with microporous rigid titanium and titanium Ti6Al4V alloy skeletons manufactured by Selective Laser Sintering. The idea is to develop entirely innovative groups of materials for applications in the form of dental implants, mainly in dental implantology but also in other areas of regenerative medicine as craniofacial surgery. The details of the case studies from craniofacial surgery mainly of the operations of the undershot mouth and from the dental implantology are given. It is the explanation of the reasons for the introduction of the new constructions and materials and a new philosophy for osseointegration using new kinds of engineering materials. The synergic use of medical knowledge, tissue engineering and materials engineering methods to produce a functional replacement for damaged tissues leads to the development of hybrid technologies of biological-engineering composite materials and a comprehensive methodology for the design of personalised tissues including dental implants but also of bones mainly of a jaw. This lecture presents the outcomes and optimisation of manufacturing conditions with a laser technology a new generation of custom, original, hybrid, microporous high-strength biological-engineering materials with microporous titanium or titanium Ti6Al4V alloy skeletons.  In the pores of regulated size and on the surface of the biological-engineering composite materials, natural cells were grown. The chapter deals with the own work done so far in this field, including computer-aided design, computer-aided additive manufacturing with selective laser sintering to produce porous skeletons materials. On the inner surface of the pores in these skeletons, the thin coatings are generated using the atomic layer deposition or sol-gel dip coating methods. For improving the cells proliferation conditions ensured by fully compatible materials, internal coatings with TiO2 and Al2O3 oxides and Ca10(PO4)6(OH)2 hydroxyapatite of the surface of pores of a microporous skeleton was used. The results of the microbiological research are included in the lecture.
