Obturator prostheses require anchoring elements in the partially resected maxilla to provide stability and oronasal separation. Anchoring elements are usually overstressed because of the lack of collateral support. Intraoral titanium implants can provide additional retention and avoid mechanical overstress of the anchoring elements in the residual maxilla. Treatment with intraoral implants into the zygoma for the support of an obturator prosthesis is reported.
闭孔义齿需要在部分切除的上颌骨中设置锚固元件,以提供稳定性并实现口鼻分隔。由于缺乏侧方支撑,锚固元件通常承受过大应力。口腔内钛植入物可以提供额外的固位力,并避免残余上颌骨中锚固元件出现机械性应力过大的情况。本文报道了通过在颧骨内植入口腔内种植体来支撑闭孔义齿的治疗方法。
