Aim of the study The purpose of this study is to conduct a rigorous analysis of the dental reconstruction methods based on the non-metallic vs. metallic register, in complete agreement with the type of dental destruction and the type of static or dynamic occlusion of the patient. Material and methods The study included 57 patients aged between 21-65 years, who reported to the dental cabinet to treat various coronary odontal lesions, extended in surface and depth, which triggered various functional disorders, especially related to physiognomy and mastication. For their morpho-functional rehabilitation the Reforpost Fiber Glass Kit (Angelus) fibrillated system was used (intra-radicular pivots) reinforced with fiberglass. Luxa Core Z was used for fixation, a nanohybrid composite with double polymerization. Results The results obtained indicate that this system shows multiple advantages: it ensures an excellent esthetic look, it shows very good retention (due to the parallel form, with slots), high radio-opaqueness that allows radiographic visualization, an elasticity that is similar to the dentine (low risk of root fracture), the conical shape translates into less tissue removed from the apical third of the radicular canal, the high percentage of fibers ensures excellent mechanical properties as, due to the longitudinal fibers, it can be easily removed and by the direct use (prefab) the working time and costs are reduced. Conclusions The choice of nano-fibrillar structures in odontal reconstructions with various types of composite materials is in complete agreement with a series of local factors, the clinical finality being characterized by the proper esthetic reconstruction and an optimum resistance, in compliance with the types of forces that act on this level.
