Lingualised occlusion in a nutshell

With its occlusal surfaces specially designed for lingualisation and characteristic abrasion facets as well as low cusp inclination, the DeltaForm® is the contemporary, semi-anatomical alternative to ABC-contact support. Developed for those who like semi-anatomical posteriors with lines of force centered on the alveolar ridge, avoidance of horizontal impulses and a self-finding "gentler" centric for their prosthetics.


  • Complex layering
  • Upper anteriors according to the traditional concept: triangular, rectangular, oval and square
  • Especially for patients with extensive denture history, narrow and rather flat front teeth design to maximise tongue space


  • Spacious, self-finding centric
  • Mortar and pestle concept with tooth-to-tooth relationship
  • Joint-adequate low cusp inclination
  • Patented large-area mortar (recess) for self-regulating occlusion
  • Reduction of the risk of hyperbalance due to abrasion facets during balancing
  • Set-up with and without A-contact without loss of stability or statics
  • Thanks to the special occlusion form, the lingualised occlusion concept directs the masticating force towards palatal onto the ridge
  • Basal groove, Preventive Shift Groove (PSG®) prevents twisting and tilting during wax-up
  • The reduced contour of the tooth base makes it easier to adapt to the alveolar ridge contour


  • Anteriors and posteriors made of highly cross-linked, filler- and fibre-free, abrasion-resistant OMP-N®
  • Posteriors, especially for secondary and tertiary structures, also available in highly modified polymer network - HMP-N®
  • Tissue-friendly, plaque-resistant
  • Chemically resistant, colour stable
  • Very easy to process and to polish
