M.A.C.® (Multiple Angle Connection) System - The international patent M.A.C.® (Multiple Angle Connection) System. In March 2015, DISPOTECH's close partnership with AMT led to an international patent for a world-first technology: the MAC® (Multiple Angle Connection) system. 

Technical specifications

M.A.C.® System (Multiple Angle Connection) is a system developed for arches and bridges created with CAD-CAM technology with angle discrepancies compared to the axis of the implant. It is therefore used where it is essential to change the entry position of the prosthetic fixing screw from the aesthetic area to the lingual or palatal surface.

The pillar is taken from the original modelling of the structure: this allows every single element to be personalised as much as possible.

• The laboratory procedure is standardised.
• No angle limit.
• Aesthetic shoulder with ideal emergency profile and required height.
• The shoulder can be covered with aesthetic material.
• There are no rotation limits and the ideal parallelism is calculated by the software.
• Structural morphology per the design.
• The connection is customised.
• The holes are very small in size and regular.
• Implant abutment and structure abutment coupling is very precise, with very small tolerances.
• Reduced possibility of infiltration.
• Standard attachment screws.
• Standard screwdriver.
• Ideal also for immediate loading.
• Positioning and removal are extremely fast and simple.
• All the advantages of a screw-retained prosthesis.
• All the advantages of a customised CAD-CAM prosthesis.
