CRISTIAN BUDACU, ALEXANDRU NEMTOI, MIHAI CONSTANTIN, MARIUS CRISTIAN MARTU, DANISIA HABA BIOMATERIALS USED IN REDUCTION AND FIXATION OF UNSTABLE FRACTURES OF THE ZYGOMATICOMAXILLARY COMPLEX This study evaluated a series of cases of fracture in the zygomaticomaxillary complex with displacement of the fractured segment which were evaluated before and after treatment with cone beam CT. The treatment perfomed was represented by titanium micro-plates and screws. The study sample which consist of 25 patients of both genders with fractures in the zygomaticomaxillary bones. After clinical examination to arrive at correct diagnosis and treatment plan, each patient was subjected to 2D and 3D reconstruction using cone beam CT. Reffering to the type of treatment was evaluated the procces of bone remodelling and also the osseointegration process of the titanium micro-plates and screws used for reduction and fixation of the fractures. The treatment performed for all patients was reduction and fixation with titanium micro-plates which were osseointegrated partially in 45 % of patients and 3 screws were not osseointegrated.
