The DynaForm Intraoral
Distractor developed by Guerrero and Bell is an example of a distraction
appliance that can be universally adapted based on the clinical
application (lengthening or widening) and anatomical location of the mandible (symphysis,
corpus, or ramus). The device consists of a universal distractor frame connected to four
flexible arms. The appliance includes two types of arm ends – screw forks and screw
rings, allowing further adaptation of the appliance based on the type of fixation
(bone-borne, tooth-borne, or hybrid).
