Dental Tribune Cosmetic June - July 2016 Use of dental implants is one of the best treatment options for partial or total edentulous patients. The aesthetically and functionally inte- grated implants can be performed reliably and reproducibly in different clinical situations with optimal long-term results.This success is achieved through “osseointegration”, which can be defined as the stable integration of an alloplastic material in the bone ensuring intimate contact between bone and implant under the functional constraint. This concept is based on the use of a titanium im- plant, inserted atraumatically into the bone with a favorable volume and density. Loading can be performed after healing peri- od, followed by appropriate prosthetic treatment. These initial concepts have undergone changes over 30 years as a result of many advances in ma- terials science and surgical techniques, offering new therapeutic approaches optimizing the im- plant treatment. The main limitations linked to the use of alloyed or non-alloyed titanium metal implants or zirconia implants result primarily from the very great difference between their mechan- ical properties and those of the peri-implant al- veolar bone, inducing considerable stress at the bone/implant interface. Moreover, the risk of cor- rosion and degradation of the implant surface in contact with the highly corrosive biological envi- ronment may cause a release of ions or toxic and/ or immunogenic particles. In this context, it can be noted that, for the alloyed or non-alloyed titanium implants, only a thin layer (10 nm) of titanium oxides (TiO2,TiO3 or TiO) is responsible for the passivation and thus the biocompatibility and osseointegration properties. Zirconia ceramic is a candidate for replacing titanium as a reference material in implantology. However, despite its obvious qualities the lack of clinical experience coupled with the fact that zirconia has very differnet mechanical properties A New Era for future of Implant Dentistry, SmartPeek Implants Fig. 2 _ Flapless approach Fig. 3 _ Final hand drill Fig. 1 Fig. 2 Fig. 3 Fig. 4 Author: Maziar Shahzad Dowlatshahi, DDS, Periodontist, IRAN 69
