Huckaba analysis /certified fixed orthodontic courses by Indian dental academy

  1. 1. Huckaba Analysis • Recommended by HUCKABA. G. W in 1964. • Compensates for radiographic enlargement of tooth image in periapical film. • It is based on the assumption that degree of magnification for a primary tooth will be the same as that of its underlying permanent successor on the same film. www.indiandentalacademy.com
  2. 2. Method • Measure• 1. Width of the primary teeth on the x-ray film y’ • 2. Width of its underlying permanent successor x’ on the x ray film • 3. Primary tooth on the cast y • 4. Width of unerupted permanent tooth is calculated by- x = x’y y’ www.indiandentalacademy.com
  3. 3. • The value obtained for the mandibular incisors on the cast and those for canines and premolars on the radiographs were added to provide the space required. • Space available is obtained by extending the brass wire from the mesio buccal of 1st permanent molar on one side, passing through the incisal edge of anterior teeth, and to the buccal cusps of 1st molar on the opposite side. • The difference in the value obtained for space required and space available is the amount of discrepancy. www.indiandentalacademy.com
  4. 4. Hixon & Oldfather Analysis • This procedures combines measuremnts from the dental casts and width measurements from the peri apical radiographs. • This method (1956); modified by Staley & Kerbers(1980) is restricted to the analysis of the supporting zone in the mandible. www.indiandentalacademy.com
  5. 5. Procedure • Measure the size of unerupted 1st & 2nd premolar in one mandibular quadrant from a peri apical radiograph. • Determination of mesio distal tooth width of the lower central and lateral incisors on the study cast to the side of the radiograph. www.indiandentalacademy.com
  6. 6. • After adding together both figures, the probable width of the permanent canine and 1st & 2nd premolars for the corresponding quadrant can be read off in the prediction graph under the column of the calculated sum total. www.indiandentalacademy.com
  7. 7. • X-axis : Mandibular incisor width measured on the dental cast + total width of 1st & 2nd premolar on the peri apical radiograph. • Y-axis : Predicted total width of permanent mandibular canine and 1st & 2nd premolar. • The formula for calculationΣ3+4+5=[(Σ 1+2+x4+x5) X 0.7158]+2.1267 www.indiandentalacademy.com
