Case of En Masse Retraction in lingual technique.

Contexts in source publication

Context 1

... Optimal Force notion in the en masse retraction approach depends on the ability to apply low forces slightly above the thresholds to retract the anterior teeth, simultaneously such forces are counteracted and dissipated in the posterior teeth without remarkable anchorage loss ( Figure 2). In short: The "optimal force" here: is the "minor force" which is slightly above the "threshold" force, (The threshold force: is least available force to move a tooth). ...

... short: The "optimal force" here: is the "minor force" which is slightly above the "threshold" force, (The threshold force: is least available force to move a tooth). Clinically, En masse retraction is an easy approach, as it is available to be applied when anchor units are the posterior teeth "2 nd premolars, 1st molars and second molars if included" ( Figure 2) [6][7][8][9][10][11][12]. In spite of the belief which most of orthodontists have regarding sequential retraction (as they think that it conservers more the anchorage units in extraction cases), the clinical views show sometimes-contradictory paradigms to such a notion ( Figure 5). ...
