Fig. 11 Suitability of potential miniscrew insertion sites in palate (green = optimal; yellow = restricted due to individual variability in bone thickness;
red = unsuitable because of thick mucosa or vascular bundles; blue dot = incisive foramen).
顎側骨釘在做植入時,需有輔助工具來操作,除了要注意安全外(避免器械掉入喉嚨),操作者也需眼明手快,務必時時演練
操作時一次到位,才不會有植入角度不佳導至穩定性不好,目前臨床上看的最多的以MARPE(miniscrew assisted rapid palatal expansion)
為最常見,主要是做上顎骨頭的擴開,以讓牙列能夠有足夠的空間排齊牙齒
骨釘在選擇位置時務必要避開神經孔神經出來的位置,以免造成損傷,
(MARPE)
