The finishing stage is the final stage of orthodontic treatment, of which the primary goal is to improve inerdigitation with minor adjustment before debonding. Here are some tips to address open bite in different parts of the arch in the finishing stage.
First, in order to improve molar occlusion, choose the better leveled and aligned arch as a reference to start setting molar occlusion. Cut down the main wire of the opposite arch and ligate together the teeth adjacent to the extraction site to prevent space reopening. Apply short vertical elastics to molars for interdigitation enhancement. Monitor closely individual tooth progression and discontinue wearing elastics once occlusal contact is established, or it may lead to an undesired side-effect of anterior open bite.
Second, if open bite is found in the middle of the arch, for example, from the distal of central incisors to the premolars in this case, a number of treatment modalities can be considered: 1. bend the rigid stainless steal main wire; 2. rebond; 3. change into a lighter arch wire and apply elastics. Never use short vertical elastics on heavy and stiff archwires which has little elasticity in order to improve interdigitation.
摘要
精緻完工是矯正的最後階段,主要目標為讓咬合更緊密,並進行拆矯正器之前的微調。在此分享一些技巧來處理此階段不同位置的開咬問題。
第一點,為提升後牙咬合緊密度,即可選擇排列較好的上排或下排牙齒當成依據,將另一排牙齒的主線截斷,拔牙區的前後牙用細鋼絲紮緊避免開縫,並以短的垂直橡皮筋拉密上下對咬。由於每顆牙的移動速度不同,每次回診都要觀察,一旦有咬合接觸該齒就不能繼續拉橡皮筋,以免過度extrude造成前牙開咬。
第二點:如果開咬區在牙弓中段,例如本案例從正中門齒遠心到小臼齒,則有三種選擇:1) 直接在粗且剛硬的主線上做bending;2) 重黏矯正器到更適當的位置;3) 換成稍微軟一點,能被橡皮筋輕微形變的主線,配合拉橡皮筋;切勿在極剛硬的主線上,如.016x.025 不鏽鋼線,拉垂直橡皮筋以增進咬合,此時的主線太硬,效果不彰。
