I am not good in explaining..lemme try still..dentistforu said:thanks toothmail
i did study the kaplan notes but a doubt
july 89 ques no.7-9 dental anat
i did not get how we figure out it is a working movement not a protrusive
could someone explain that
thank u
Had it been a protrusive moment, there would have been a vertical 'scratch'. This is because, the mandile would have moved front. That means the maxillary teeth would have made a 'mesial-distal' direction mark.Now since the diagram shows it as a horizontal 'scratch', we can safely assume that it is a lateral moment and not protrusive
