Clinical Evaluation of Implant Suprastructures Depending on the Biomechanical Characteristics of the Materials Used

The choice of an appropriate implant suprastructure, which should be made according to the individual characteristics each patient, is a leading factor in achieving good aesthetic results. aim this study was assess clinical behavior suprastructures functional, biological, and criteria. Methods: enrolled 23 patients with total 27 implants different areas oral cavity. following groups were studied for period 1 year: Group A, control group (monolithic crowns zirconium dioxide on titanium base); B lithium disilicate individualized (custom) alloy abutment); C (implant abutment). functional criteria included suprastructure fracture, crown fracture or chipping, screw loosening, faceting wearing occlusal surface crown, articulation relations, fracture. biological indicators probing pocket depth (PPD) Mombelli et al.’s plaque index bleeding probing. bone loss level measured radiographically.
