'anteroclusion' is formed from the combining prefix 'antero-' meaning 'front, forward' (from Latin/Neo-Latin usage of Latin 'ante' meaning 'before') and 'occlusion' from Latin 'occludere' meaning 'to shut' or 'to close'.

'anteroclusion' is a modern medical/technical coinage (Neo-Latin/English) combining 'antero-' + 'occlusion'. The elements derive from Latin roots used in medical terminology and were combined in English dental literature to denote a forward (anterior) occlusal relationship.

The formation originally described the idea of a 'front closure' or 'front contact.' In dental usage it has come to mean specifically a forward positioning of the upper teeth relative to the lower teeth (excessive overjet).
