DIAGNOSTIC SETUP
H.D. Kesling (1956) Supplemental diagnostic aid Practical aid in treatment planning Derive maximum clinical information A set of trimmed & polished casts
![Page 7: Kesling dagnostic setup](https://reader030.vdocuments.net/reader030/viewer/2022012819/554b4e64b4c905793d8b4582/html5/thumbnails/7.jpg)
DIAGNOSTIC SETUP
Individual teeth & associated alveolar processes- sectioned off & replaced in desired positions
Simulate the various planned tooth movements
Not necessary to coordinate with cephalometric tracing
Allowance for inevitable anchorage loss
![Page 8: Kesling dagnostic setup](https://reader030.vdocuments.net/reader030/viewer/2022012819/554b4e64b4c905793d8b4582/html5/thumbnails/8.jpg)
REQUIREMENTS
Well trimmed casts Fret saw with blades Modelling wax Wax knife Alcohol torch/ Spirit lamp

PROCEDURE
Maxillary & mandibular study casts prepared
Bases trimmed parallel to the occlusal plane
Horizontal cuts made in the mandibular cast 3mm below the gingival margin using
Fretsaw blade

PROCEDURE
Vertical cuts are made to separate individual teeth
All teeth except second & third molars are removed
Mesial & distal ends of roots of teeth are trimmed – seating in new position

PROCEDURE
Wax blocks placed in the slits formed while cutting the teeth away
Mandibular incisors arranged on the study cast at an angle of 65 degrees to the Frankfort Horizontal plane
Canines & premolars are placed in the correct contact relationships

PROCEDURE
If the remaining space is inadequate to receive the first molars extraction indicated
Eliminate 1st premolars from the setup & place 2nd premolars in contact with canine or perform incisor or proximal stripping
Maxillary teeth cut & repositioned in the wax setup articulating them with the mandibular setup

Borderline cases: Extraction / non extraction 1st premolar or 2nd premolar
Possible types of occlusal arrangement in abnormal occlusal problems
Patient can be motivated- simulating various corrective procedures
