“Steps to explain different types of extractions in orthodontics: Q&A guide”
Wilkinson advocated the extraction of all four first permanent molars between the ages of 8½ to 9½ years.
The basis for such extraction is the fact that the first permanent molars are highly susceptible to caries.
Wilkinson’s Extraction Advantages
- Their extraction provides additional space for the eruption of the third molars, thus impaction of third molars can be avoided.
- Crowding of the arch is minimized.
- The chances of dental caries are reduced because crowding is absent.
- Oral hygiene is effective.

Wilkinson’s Extraction Disadvantages
- Extraction of first molars offers limited space to relieve crowding.
- Second bicuspids and second molars rotate and may tip into the extraction space.
- Mesial tipping of the second molar occurs.
- Removal of the first molars deprives the orthodontist of adequate anchorage for any orthodontic appliance.
- Mesial tipping causes improper proximal contact, which leads to the accumulation of food, which causes periodontal problems.
