Where should the contact point be located on the distal surface of a maxillary first premolar?

Show Answers

At the middle third of the proximal surface, with the lingual embrasure larger than the facial embrasureAt the occlusal third of the proximal surface, with the lingual embrasure larger than the facial embrasureAt the occlusal third of the proximal surface, with the facial embrasure larger than the lingual embrasureAt the middle third of the proximal surface, with the facial embrasure larger than the lingual embrasure

Explanation

The correct location for the contact area on the distal surface of the maxillary first premolar is the middle third of the proximal surface, where the lingual embrasure is greater in size compared to the facial embrasure. This positioning helps maintain proper tooth alignment and embrasure form.
