NANCE CAREY’S ANALYSIS
•MEASURE THE MESIODISTAL WIDTH OF THE ERUPTED PERMANENT TEETH
•MEASURE THE WIDTH OF EACH UNERUPTED TOOTH,CUSPIDS AND BICUSPIDS FROM IOPA RADIOGRAPHS
•THE TOTAL MESIODISTAL WIDTH OF ALL TEETH IN EACH QUADRANT WILL INDICATE SPACE REQUIED TO ACCOMMODATE THE PERMANENT TEETH
•USING BRASS WIRE,MEASURE THE ARCH PERIMETER
•COMPARE THE SPACEREQUIRED AND SPACE AVAILABLE TO ARRIVE AT THE ARCH LENGTH DISCREPANCY

HUCKABA’S ANALYSIS
 HE USED BOTH STUDY CASTS AND RADIOGRAPHS FOR DETERMING THE WIDTH OF
UNERUPTED TOOTH
 TO COMPENSATE FOR ENLARGEMENT OF RADIOGRPAHIC IMAGES MEASURE AN
OBJECT THAT CAN BE SEEN BOTH IN RADIOGRAPH AND ON THE CAST SUCH AS
PRIMARY MOLAR TOOTH.ACCURACY OF THIS METHOD OF DETERMING THE WIDTH OF
THE UNERUPTED TOOTH IS FAIR TO GOOD ,DEPENDING UPON THE QUALITY OF THE
RADIOGRAPHS AND THEIR POSITION IN THE ARCH
 THIS TECHNIQUE CAN BE USED BOTH IN MAXILLARY AND MANDIBUALR ARCHES IN
ALL ETHNIC GROUPS
 THEN A SIMPLE PROPORTIONAL RELATIONSHIP CAN THEN BE ESTABLISHED AS

MOYERS MIXED DENTITION ANALYSIS
Kondapaka V,
Sesham VM, Neela
PK, Mamillapalli
PK,2015
Moyer's mixed dentition analysis was found to be the most reliable method
for both boys and girls of Nalgonda population .(13-16 YRS)
Durgekar Sujala
Ganapati, Naik
Vijay,2009
BELGAUM:The actual measurements were compared with the predicted
values obtained with the Moyers probability tables at the 35 th , 50 th , and
75th percentile confidence. Moyers prediction tables are not an accurate
method to estimate tooth dimension There is a variation in the mesiodistal
tooth dimensions among males and females
Galvão
M, Dominguez
GC, Tormin
ST, Akamine
A, Tortamano A, de
Fantini SM, 2013
Based on the literature available, we can conclude that Moyers mixed
dentition analysis must be carefully used, since the majority of the articles
analyzed showed that the probability of 75% was not as accurate as
expected, leading to the need of adapting the probability levels depending
on the study population

There was significant statistical difference between values of the present
study and Moyer's prediction values. (RAJASTHANI POPULATION)

Buwembo, Sam
Luboga,2004
Moyer’s method of prediction may have population variations. For one to
be sure of the accuracy while using Moyer’s method it may be safer to
develop prediction tables for specific populations.

TANAKA JHONSTON ANALYSIS
• FROM PERMANENT 1 ST MOLAR ON ONE SIDE ,MARK THE DISTANCES ON CASTS IN SEGMENTS TO THE PERMANENT 1 ST MOLAR ON THE OPPOSITE
SIDE.MEASURE THESE SEGMENTS OVER THE CONTACT POINTS
• ADD THE MEASUREMENT FORM STEP 1 TO DETERMINE THE TOTAL ARCH CIRCUMFERENCE
• MEASURE THE MESIODISTAL WIDTHS OF MANDIBULAR CENTRAL AND LATERAL INCISORS
• DIVIDE THE SUM OF THE WIDTHS OF THE MANDIBUALR INCISORS BY 2 AND ADD 10.5 MM FOR THE MANDIBULAR ARCH
• THIS TOTAL GIVES THE ESTIMATED SIZE OF THE MANDIBULAR CANINE AND THE PREMOLARS ON ONE QUADRANT
• DOUBLE THE TOTAL IN STEP 6 FOR CANINES AND FOUR PREMOLARS IN THE MANDIBULAR ARCH
• SUBTRACT THIS DIMENSION FROM THE REMAINING SPACE AVAILABLE IN THE ARCH TO GIVE A POSITIVE OR NEGATIVE TOTAL ARCH SPACE

 AVAIALBLE ARCH LENGTH=TOTAL ARCH LENGTH-SUM OF INCISORS+2
PREDICTED WIDTH
 +VALUE=SPACE SURPLUS
 -VALUE=SPACE DEFICIT
 TANAKA JHONSTON PREDICTION VALUES:
 ONE HALF M-D WIDTH OF FOUR LOWER INCISORS+10.5 mm=ESTIMATED OF
MANDIBULAR CANINE AND PREMOLAR ONE QUADRANT
 ONE HALF M-D WIDTH OF LOWER INCISORS+11 mm=ESTIMATED WIDTH OF
MAXILLARY CANINE AND PREMOLAR IN ONE QUADRANT

INFERENCE
 IF THE RESULT IS POSITIVE ,THERE IS MORE SPACE AVAILABLE IN THE ARCH THAN
IS NEEDED FOR UNERUPTED TEETH
 IF THE RESULT IS NEGATIVE ,THE UNERUPTED TEETH REQUIRE MORE SPACE IS
AVAILABLE TO ERUPT INTO IDEAL ALIGNMENT
 ADVANTAGE
 IMPROVING ON THE MOYER’S ANALYSIS ,IT IS RELATIVELY ACCURATE FOR
CHILDREN OF EUROPEAN ANCESTRY
 THE TECHNIQUE INVOLVES SIMPLE,EASILY REPEATED PROCEDURES AND
MINIMAL MATERIAL NEEDS
 IT DOES NOT USE PREDICTION CHART

MOYERS VS TANAKA JHONSTON
Shobha MB, Ajs
S, Manoj
E, Sridhar
G,2016
Overestimated values were noticed in males and females of both arches
with TJ equation; Males showed no significant difference at Moyers 50(th)
percentile (50/100), in both the arches where as females showed higher
values in mandibular arch and underestimated values in maxillary arch.
At Moyers 75(th) percentile, overestimated values were noticed in males
both the arches whereas in females lesser values were observed.

Tripathi AM, Jaiswal

Differences between the actual and predicted values of upper and lower
permanent canines and premolars were statistically significant in both

Tanaka and Johnston's method cannot accurately predict the m-d widths.
Moyers' prediction tables can be used to estimate the m-d widths of
unerupted canines and premolars closer to 50% probability level.

MOYERS VS TANAKA JHONSTON
BARUN
DASGUPTA,2012
Tanaka and Johnston regression equations under-estimated the
widths of permanent canines and premolars. On the other hand, there
no statistically significant differences between actual mesiodistal widths of
canines and premolars and the predicted widths from Moyers charts at
50% level for the lower and upper arches, among Bengali population.

PRIMARY DENTITION
 Gianelly in his personal communication, proposed a prediction method based on
the mesiodistal widths (MDWs) of primary mandibular canines and first molars with
an idea for early prediction of unerupted permanent mandibular teeth widths. This
was presented in Boston University (BU), and hence the method was named as BU
approach. Subsequently, two studies were carried out on this approach, one on
Iowa population and the other on Iraqi population.

 Limitation:using primary dentition analysis is that the changes in arch dimensions
as well as tooth position and inclination that maintain the balance among the
various functional and structural demands placed on the face and dentition are
difficult to predict in an early age
