Teeth Arrangement

Maxillary Central IncisorsFront : long axis parallel to the vertical axis.

Side :slopes labially at about 14◦.

Occlusal plane : incisal edge is in contact with occlusal plane.

Maxillary lateral incisorsWhen viewed from

Front : long axis slopes towards midline at incisal edge.

Side :slopes labially at about 20◦.

Occlusal plane : incisal edge is 1mm short of Occlusal plane.

Maxillary canineFront : long axis parallel to the vertical axis.

Side :long axis parallel to the vertical axis.

Occlusal plane : cuspid tip is in contact with occlusal plane.

Mandibular central incisors When viewed from

• Front : long axis inclines slightly towards the vertical axis.

• Side : slopes labially.

• Occlusal plane : incisal edge is 0.5-1 mm above the occlusal plane.

Mandibular lateral incisorsWhen viewed from

• Front : long axis inclines towards the vertical axis.

• Side : slopes labially less than central incisor.

• Occlusal plane : incisal edge is 0.5-1mm above occlusal plane.

Mandibular canineWhen viewed from

Front : long axis inclines towards the midline.

Side : slopes lingually.

Occlusal plane : cuspid tip is 0.5-1mm above occlusal plane.

Class 1 canine relationship

Overjet overbiteOverjet horizontal overlap is 0.5-1mm.Overbite is the vertical overlap and it of about 1-2mm.

Posteriors

Maxillary 1st premolarWhen viewed from

• Front : long axis parallel towards the vertical axis.

• Side : long axis parallel towards the vertical axis.

• Occlusal plane :buccal cusp is in contact with occlusal plane and palatal cusp is 1mm short of occlusal plane

Maxillary 2nd premolarWhen viewed from

• Front : long axis parallel towards the vertical axis.

• Side : long axis parallel towards the vertical axis.

• Occlusal plane : Both buccal cusp and palatal cusp are in contact with occlusal plane.

Maxillary 1st molar

When viewed from

• Front : long axis slopes buccaly.

• Side : long axis slopes distally.

• Occlusal plane : only mesiopalatal cusp in contact with occlusal plane.

Maxillary 2nd molarWhen viewed from

• Front : long axis slopes buccaly and more steeply than the 1st molar.

• Side : long axis slopes distally more steeply than the 1st molar..

• Occlusal plane : only mesiopalatal cusp is nearest to occlusal plane.

Maxillary teeth set, checked on a glass plate

Mandibular 1st molar Front : long axis leans lingually.

Side : long axis lean mesially.

Occlusal plane : all cusps are at higher level than n 2nd premolar, buccal and distal cusps higher than the other two.

Occlusal contact : the mesiobuccal cusp occludes n the fossa between upper 2nd premolar ant 1st molar.

Mandibular 1st premolarFront : long axis parallel towards the vertical axis.

Side : long axis parallel towards the vertical axis.

Occlusal plane : lingual cusp below the horizontal plane, buccal cusp is 2mm above the occlusal plane.

Occlusal contact : buccal cusp contacts the mesial marginal ridge of upper first premolar.

Mandibular 2nd premolarWhen viewed from

• Front : long axis parallel towards the vertical axis.

• Side : long axis parallel towards the vertical axis.

• Occlusal plane : both cusp are 2mm above the occlusal plane.

• Occlusal contact : buccal cusp contacts the fossa between the two upper premolars.

Mandibular 2nd molar• Front : long axis leans more lingually.

• Side : long axis lean more mesially.

• Occlusal plane : all cusps are at higher level than 1st molar, buccal and distal cusps higher than the other two.

• Occlusal contact : the mesiobuccal cusp occludes n the fossa between the two upper molars.

Carving and polishing.1. Adapt the softened roll of

baseplate wax on the facial surface and extend.

2. Seal the baseplate wax around the neck of each tooth with a wax spatula.

3. Carve the gingival margins of anterior teeth with a carver held approximately at 60◦

4. Carve the gingival margins of posterior teeth by a carver held approximately at 45◦.

5. Use a gas touch to flame the wax surface taking care not to over heat the gingival contours. The maxirally waxed denture shows the gingival contour and the root forms.

6. Adapt the baseplate wax on lingual surface of the trial denture and carve.

Completed Teeth

Compensatory curves

The Anteroposterior and lateral curvatures in the alignment of the occluding surfaces and the incisal edges of the artificial teeth that are

used to develop a balanced occlusion.

Curve of spee.

The anatomic curve established by the occlusal alignment of the teeth, as projected onto the median plane, beginning with the cusp tip of mandibular canine and following the buccal cusp tips of the premolars and molars and continuing with the anterior border of the mandibular ramus and ending with the anterior most portion of the mandibular condyle.

Curve of wilsonIt is used to arrange the molarsThe lower teeth are inclined lingually, giving prominence to the buccal cusps and brining them into heavy occlusal contact with the upper buccal cusp during lateral movements on working side

Curve of monsoon

Curve of occlusion in which each cusp and incisal edge touches a segment of a surface of a sphere 8 inches in diameter with its centre in the region of the glabella

A smile never goes out of style.significant dental innovation specially for the

older generation…!!
