Angulated abutments shall be used, if the application of direct superstructure is impossible, difficult or unreasonable. Such situations include the following cases:
• anatomic and topographic features of the jaws, preventing parallel implants’ installation and requiring one of the angulated abutments’ application;
• all cases of impossible insertion of direct abutments or in cases of uncertainty of the safe functioning of orthopedic constructions based on such structures;
• when the insertion of a certain angulated superstructure ensures, to the fullest extent, the required aesthetics in the frontal dentition areas etc.
The set of angulated abutments, designed to satisfy the requirements to various prosthetics peculiarities, comprises a wide choice of abutments.
Due to this factor, it is possible to create superstructures with the following characteristics:
• hexagon platform diameters: 4.5, 5.0 and 5.5 mm;
• abutment vertical plane inclination: 15° and 25°;
• abutment horizontal plane rotation: ±30°;
• abutment height from gingival part: 5, 7 and 10 mm;
• abutment gingival part height: 1, 2, 3, 4, 5 and 6 mm
