S for duplication o facial and lingual contours because facial and lingual surfaces are slightly over/under contoured and facial/buccal and lingual contours require adjustment, shifting HOC to occlusal/incisal/cervical positions. Minor adaptation occurs at the cervical margin. S for duplication of occlusal surfaces and occlusal contacts because cebtric contacts exhibit minor absence or over-contouring, causing inefficiency in incisal/canine guidance, meeting only 2 out of 3 criteria. R for duplication of proximal contacts and embrassure spaces because nearly ideal shape, size, and location of proximal contact areas and four embrassure spaces facilitate smooth fit and function. R for overall tooth anatomy because the wax model presents an ideal shape.
