TOOTH ARRANGEMENT
Grade A	Teeth are arranged with proper inclinations. Mandibular 1st and 2nd molars directly over ridge. Minimum of 1.5mm horizontal overlap of maxillary and mandibular molars. Buccal surfaces of premolars are on a line as drawn between buccal surface of 1st molar and cusped. Posterior teeth in occlusal contact. Zero degree teeth set to exactly a flat plane. Anatomic teeth set to a compensating curve in harmony with condylar and anterior guidance. Waxed areas are neat, clean, smooth, and properly festooned to stimulate the natural healthy dentition. Occlusal plane reasonably oriented to anatomic landmarks. No wax on occlusal surfaces of teeth or under record base. Articulator and casts clean.
Grade B	Minor discrepancies from above which do not compromise the quality of the clinical treatment. Teeth arranged correctly, but some minor contact discrepancies. Waxed areas correctly contoured, but some excess wax on teeth. No wax on occlusal surfaces.

Grade C	Tooth arrangement requires further alterations to be clinically acceptable. Buccal surfaces of premolars off line, as drawn between 1st molar and cuspid, by 2 mm. Inclinations of anterior teeth are unnatural. occlusal plane obviously too high or low. Wax between contact areas of anterior teeth. Moisture incorporated into wax. Evidence of wax on occlusal surfaces. Teeth loose in wax. No horizontal overlap between posterior teeth. Occlusal plane noticeably angled laterally or anterior-posteriorly.
Grade E	Tooth arrangement prevents clinically acceptable complete denture treatment. Tooth position forces upper member of articulator out of its terminal hinge position (ball element not against vertical wall of articulator). Wax is dirty. Teeth reversed. Cast damaged. Bases unstable. mandibular molars not centered over mandibular ridge. Teeth grossly out of normal position.
