 The basic idea behind so-called bracket placement rules is that the position of the bracket relative to the crown in malocclusion is reproducibly specified by the vertical¹ incisal edge distance along the facial clinical crown axis FACC. This value can be fix or calculated variably from parameters such as crown heights, distance to other reference crowns or other measures. Among other things, distance rulers (e.g., the "Bantleon ruler") are used as placement aids.\\ The basic idea behind so-called bracket placement rules is that the position of the bracket relative to the crown in malocclusion is reproducibly specified by the vertical¹ incisal edge distance along the facial clinical crown axis FACC.

 In the [[fa_bonding|FA_Bonding]] module, various such placement rules can be selected and applied for the initial placement of the selected virtual bracket. In the [[fa_bonding|FA_Bonding]] module, various such placement rules can be selected and applied for the initial placement of the selected virtual bracket.

 When applying this widely used methodology, it is often ignored that the crown-centered measurement of the perpendicular¹ (projected) incisal edge distance is not unique, but depends on the direction of measurement (i.e., the angle between the slot-parallel distance ruler and the FACC).\\ When applying this widely used methodology, it is often ignored that the crown-centered measurement of the perpendicular¹ (projected) incisal edge distance is not unique, but depends on the direction of measurement (i.e., the angle between the slot-parallel distance ruler and the FACC).\\
 In der Praxis wird diese Winkel vor dem Hintergrund der unbewussten Validierung durch den erfahrenen Behandler meist so eingestellt, dass die finale Klebehöhe den Anforderungen der Straight-Wire-Technik bestmöglich entspricht.\\ In der Praxis wird diese Winkel vor dem Hintergrund der unbewussten Validierung durch den erfahrenen Behandler meist so eingestellt, dass die finale Klebehöhe den Anforderungen der Straight-Wire-Technik bestmöglich entspricht.\\
