Selection of teeth / fixed orthodontics courses

  1. 1. SELECTION OFSELECTION OF TEETH FORTEETH FOR COMPLETECOMPLETE DENTUREDENTURE PROSTHESISPROSTHESISINDIAN DENTAL ACADEMY Leader in continuing dental education www.indiandentalacademy.com www.indiandentalacademy.com
  2. 2. Teeth selection for complete denture is best understood if the anterior teeth are considered separately from the posterior teeth. The anterior teeth are primarily selected to satisfy esthetic requirements, whereas posterior teeth are selected to satisfy masticatory requirements. www.indiandentalacademy.com
  3. 3. ANTERIOR TEETH a.SIZE OF THE ANTERIOR TEETH Anatomic entities used as a guide for anterior teeth size: 1.Size of the face: Width of the central incisor = one sixteenth of the bi-zygomatic width of the face. Combined width of the six anterior teeth = slightly less than one third of the bizygomatic breadth of the face. www.indiandentalacademy.com
  4. 4. www.indiandentalacademy.com
  5. 5. 2. Size of the maxillary arch – the distance between the incisive papilla and the hamular notch on one side is added with the distance between two hamular notches. This gives a combined width of all anterior and posterior teeth of the maxillary arch. www.indiandentalacademy.com
  6. 6. 3. Incisive papilla and the canine eminence – the combined width of the six anterior teeth is equal to the length of a line drawn on the cast at the distal termination of one canine eminence to the other. Intra-orally, the patient is requested to relax with the lips touching. A mark is made at the corners of the lips. The distance between the two marks on either side is equal to the combined width of all the anterior teeth. www.indiandentalacademy.com
  7. 7. 4. Maxillo-Mandibular Relation – Any disproportion in the size between the maxillary and mandibular arches influences the length, width and position of the teeth. If mandible is protruded; anterior teeth are larger, if mandible is retruded; anterior teeth are smaller. 5. Contour of the residual ridge – teeth should be placed in relation to follow the contour of the residual ridges that existed when natual teeth were present. www.indiandentalacademy.com
  8. 8. 6. Vertical distance between the ridges – according to the available inter-arch space length of the teeth can be selected. Minimal of the denture base should be visible in the final prosthesis. 7. Lips – During relaxed state the labial surface of the maxillary anterior teeth support the upper lip. When the teeth are together the incisal edge of the maxillary incisors supports the superior border of the lower lip www.indiandentalacademy.com
  9. 9. FORM OF THE ANTERIOR TEETH Factors governing the form of the anterior teeth: 1.Form and contour of the face: from the frontal aspect the shape of the face can be classified as –  Square  Square tapering  Tapering  Ovoid www.indiandentalacademy.com
  10. 10. From the lateral aspect the facial profile can be classified as: Straight Concave Convex Form of the artificial anterior teeth should conform to the form of the face. www.indiandentalacademy.com
  11. 11. 2. Sex: Curved features are associated with feminity and square features are associated with masculanity. Teeth selected for females are more ovoid or tapering; whereas for males are more squarish, and sharp edged. 3. Age: Aging process affects the entire masticatory apparatus in general including the teeth. Teeth wear at the incisal edges, labial surface becomes more flatter and outline appears more squarish. www.indiandentalacademy.com
  12. 12. SELECTION OF POSTERIOR TEETH: Factors of selection – size, number, form and shade. 1. Form of the posterior teeth: The occlusal form of the posterior teeth is of primary concern. The proximal, buccal, lingual should be contoured so that they will feel natural, masitcate food, and arranged in suitable contact. Cusp form of teeth are used if balanced occlusion is being developed. If posterior teeth are expected to disocclude in eccentric jaw movements either the cusp form or monoplane teeth can be used. If the posterior teeth are to be arranged in neutrocentric occlusion monoplane teeth are selected.www.indiandentalacademy.com
  13. 13. SELECTION OF POSTERIOR TEETH: Factors of selection – size, number, form and shade. 1.Size and number of posterior teeth:  Must support the cheek, tongue during rest and function.  Buccolingual dimension of the artificial teeth should be less than the natural teeth  Anterioposterior dimension of posterior teeth is determined by the length of edentulous span extending from distal of the cuspid to the ascending ramus of the mandible (just short of the reteromolar papilla)www.indiandentalacademy.com
  14. 14. SELECTION OF POSTERIOR TEETH: (cont’d) 2. Form of the posterior teeth: The occlusal form of the posterior teeth is of primary concern. The proximal, buccal, lingual should be contoured so that they will feel natural, masitcate food, and arranged in suitable contact. Cusp form of teeth are used if balanced occlusion is being developed. If posterior teeth are expected to disocclude in eccentric jaw movements either the cusp form or monoplane teeth can be used. If the posterior teeth are to be arranged in neutrocentric occlusion monoplane teeth are selected. www.indiandentalacademy.com
  15. 15. Shade of the artificial teeth: Should be in harmony with surrounding structures – skin, hair, and eyes. Shade selection should be done under natural light, with the patient positioned in upright postion and atleast six to eight feet from the dentist. Canine usually is darker than the anteriors. Posterior teeth should be in harmony with the anterior teeth. Premolar tooth is critical for esthetics. If being arranged for esthetics premolar should be lighter than the remaining posterior teeth.www.indiandentalacademy.com
