The article discusses the non-parallel technique in restorative dentistry with the Vertical Splint Mate System. This technique eliminates the need for amalgam and provides retention and venting of the crown for cementation. Using pin inlays or onlays for periodontal splinting improves the retention of these restorations with minimum loss of tooth structure. A pin ledge preparation should be created with a bevel on mesial, distal and cingulum area for an anterior bridge. It is necessary to have mesial and distal pins under 45 degrees from one another.
