SPHERICAL ABUTMENT NSKA - 1
1. Connection and safe fixing of removable prostheses on the implants are provided by means of two abutments of this construction:
• Direct abutment with spherical head and neck. This abutment shall be inserted into the implant by means of internal hexagon at the butt of spherical head and a hexagon 1.25 mm wrench. This superstructure, hereinafter – patrix, constitutes the implant part of the detachable connection.
• Prosthetic abutment, hereinafter – matrix, represents a titanium case with a dense nylon cap pressed therein. NSKA1 superstructures comprise different nylon caps of various densities. The titanium case is fixed firmly in the removable prosthesis.
• Safe functioning of the removable prosthetic construction based on NSKA-1 superstructure is provided by means of solid spherical interlock, of the nylon cap matrix with the patrix neck.
2. Main structural constituents of spherical abutments:
• 2.50 mm diameter spherical head with and a butt hexagon;
• Neck coupling with a nylon cap of prosthetic superstructure;
• Gingival part;
• Neck of direct superstructure within the implant;
• Thread segment;
• Leading cylinder.
3. Spherical abutments NSKA-1 differ in the size of the gingival parts:
• Three diameter sizes – 4 mm, 4.5 mm and 5.0 mm;
• Seven height sizes – 0.50 mm, 1.00 mm, 2.00 mm, 3.00 mm, 4.00 mm, 5.00 mm and 6.00 mm.
SPHERICAL ABUTMENT NSKA - 2
1. Spherical abutment NSKA - 2 is designed to build removable prostheses on the implants, ensuring the possibility of immediate loading of the prosthetic device after completion of the implantation procedure (on the same day).
2. Connection and safe fixing of removable labile prostheses on the implants are provided by means of two abutments of the NSKA-2 superstructure:
• Direct abutment with special spherical head and neck. This abutment, considered as patrix, constitutes the implant part of the detachable connection. The patrix shall be inserted into the implant by means of the specially assigned body square part under the neck.
• Prosthetic abutment – matrix, shall be considered as counterpart of the detachable connection. Structurally, such matrix represents a titanium case with a resilient rubber ring pressed therein. Superstructure NSKA-2 comprises rubber rings of various density and elasticity. The titanium case is firmly fixed in the removable prosthesis.
• Safe functioning of the removable prosthetic construction based on the NSKA-2 superstructures is provided by means of solid spherical interlock, of the rubber ring matrix with the patrix neck.
3. Main structural constituents of spherical abutments are the following:
• 1.8 mm diameter spherical head;
• Neck coupling with a resilient rubber ring of prosthetic abutment – matrix;
• Gingival part;
• Neck-seal of the spherical abutment within the implant;
• Thread segment;
• Leading cylinder
4. Spherical abutments of the construction NSKA-2 differ in their gingival parts size:
• Three diameter sizes – 4 mm, 4.5 mm and 5.0 mm;
• Seven height sizes – 0.50 mm, 1.00 mm, 2.00 mm, 3.00 mm, 4.00 mm, 5.00 mm and 6.00 mm.
The NANOPLANT HÖCHST System provides 2 types of impression taking transfers:
• monolithic transfer NAT-1+2;
• split two-component transfer, comprising an implant gingival part NAT-1 and impression parts NAT-2 and NAT-2a.
Based on these transfers, impressions can be taken in two ways:
• traditional
• innovative
The traditional method of taking impressions is performed by means of individual trays with perforation and monolithic transfer.
For the innovative method of taking impressions, less laborious and more operative, split transfer and traditional closed tray is used.
