'antero-occlusion' originates from Neo-Latin/Latin combining the prefix 'antero-' (from Latin 'anterior', meaning 'before, front') and 'occlusio' (from Latin 'occludere', meaning 'to shut, to close').

'antero-occlusion' changed from Neo-Latin formation such as 'antero-occlusio' (a combination of 'antero-' + 'occlusio') and was adopted into English medical/dental usage as 'antero-occlusion'.

Initially it literally meant 'front closing' (the act/condition of closing at the front); over time it came to be used specifically for the dental condition describing a forward relationship of the teeth (an anterior malocclusion).
