Apparently for a while there was also the technique of drilling 'retentive pins' into the tooth, then wires were attached and pulled on. The risk for pulpal damage, retired the technique when brackets came along.
However, the technique of drilling into the tooth is still active in Brazil today according to a paper (9). In this instance they drill a hole all the way through the tip of the tooth. A highly skilled surgeon is required, again, because of the risk to the pulp.

Old discarded techniques
I thought it was interesting to find this older article from 1981: 'Treatment of Impacted Cuspids -The Hazard Lasso' (sic! not even the 'hazard of'(8). The authors warn against a 'long used' technique of putting a wire all around the impacted canine instead of the, at the time, the newer technique of bonding some kind of bracket to pull on. The lasso method often caused ankylosis.
Additionally, the movement of an impacted tooth
involves risks of discoloration, devitalization, root
resorption, loss of cervical bone and long clinical
crown with lack of attached gingivae. The patient
and/or parents should be fully aware of these risk
factors.
