Comparison between an Acrylic Splint Herbst and an Acrylic Splint Miniscrew-Herbst for Mandibular Incisors Proclination Control

Table 1

Cephalometric variables analysed and their description.

(1) Maxillary bone base	A/Olp: distance from point A to the Olp line (mm)
(2) Mandibular bone base	Pg/Olp: distance from point Pg to the Olp line (mm)
(3) Mandibular length	Ar/Olp + Pg/Olp: condile plus mandibular base (mm)
(4) Skeletal discrepancy	A/Olp − Pg/Olp: maxillary bone base minus mandibular bone base (mm)
(5) Skeletal class	AN/NPg: angle formed by the lines AN and NPg (degrees)
(6) Skeletal divergence	SN/GoMe: angle formed by the lines SN and GoMe (degrees)
(7) Maxillary incisor	Is/Olp: distance from point Is to the Olp line (mm)
(8) Mandibular incisor	Ii: distance from point Ii to the Olp line (mm)
(9) Mandibular incisor proclination	Ii/GoMe: angle formed by the mandibular incisor axis and the mandibular plane (GoMe); (degrees)
(10) Overjet	Is/Olp − Ii/Olp: maxillary incisor minus mandibular incisor (mm)
(11) Maxillary molar	Ms/Olp; Ms: distance from point Ms to the Olp line (mm)
(12) Mandibular molar	Mi/Olp: distance from point Mi to the Olp line (mm)
(13) Molar relationship	Ms/Olp − Mi/Olp: maxillary molar minus mandibular molar (mm)
(14) Condyle position	Ar/Olp: distance from point Ar to the Olp line (mm)
