The cause of some peri-implant problems may be primarily attributable to the design of the prosthesis. A screw-retained interim implant may be advisable for reversibility and to avoid peri-implant cement, although screw retention may be difficult for maxillary anterior implants with a labial angulation. In the treatment described, a interim screw-retained crown was attached to a dynamic abutment with a lingual screw access hole to obtain a correctly fitting restoration.
一些种植体周围问题的原因可能主要归因于修复体的设计。对于可摘性和避免种植体周围粘固剂来说，螺丝固位的临时种植体可能是明智的选择，尽管对于唇侧倾斜的上颌前牙种植体来说，螺丝固位可能具有挑战性。在描述的治疗中，临时螺丝固位冠被连接到带有舌侧螺丝通道孔的动态基台上，以获得合适的修复体。
