A block of wax corresponding to the position of the maxillary left central incisor is removed from the occlusal rim
The wax surrounding this area is softened with a hot spatula
Sometimes the base plate may interfere with proper placement of the teeth. When this occurs a portion of the base plate is removed
The maxillary central incisor is placed so that the long axis shows a slight distal inclination to the perpendicular
The incisal edge is on the occlusal plane
The neck of the tooth should be slightly depressed
The facial surface of the tooth is nearly perpendicular to the occlusal plane
The maxillary lateral incisor has slightly more distal inclination than the central incisor
The incisal edge is usually 0,5 to 1 mm above the occlusal plane
The neck of the maxillary lateral incisor is depressed more than the central incisor, Although the labial surface will be nearly in line with the central incisor this occurs a portion of the base
The maxillary canine is placed so that the long axis is almost vertical
It may have a slight distal inclination but should not lean mesially
The neck of the maxillary canine is prominent
The maxillary canine tooth is an important tooth in any tooth arrangement because it forms the corner of the dental arch
The maxillary canine has two planes on the facial surface, the mesial plane should follow the contour of the anterior teeth while the distal plane will be in line with the posterior teeth
The neck of the tooth is predominant as it supports the corner of the patient’s mouth
The labiolingual position of the maxillary central incisors should be judged by the evaluation of the location of the incisive papilla
The maxillary central incisors should be located approximately 8 to 10 mm labially apart from the incisive papilla
The mandibular central incisors are set with the long axis perpendicular to the occlusal plane with the neck depressed
The mandibular lateral incisors are set with a slight distal inclination and with the facial surface at a right angle to the occlusal plane
The mandibular canines have more distal inclination than the lateral incisors and the neck is set prominently
