Implant treatment should be restoratively driven, however at times, ideal implant positioning may be sacrificed for surgical convenience at the expense of restorative complexity. A prosthesis incorporating a novel design was constructed to restore two converging implants placed in close proximity utilizing standard implant impression componentry and simple clinical stages. As the use of angulated screw channel technology was not possible, a customized cast "rest" abutment and overlying telescopic crown was fabricated that facilitated access for oral hygiene and retrievability as required. The complexity of the case design was transferred to the laboratory phases of construction. The case presented a satisfactory clinical outcome for an initially challenging implant presentation and reinforced the need to work closely with the laboratory technician.
种植治疗应基于修复需求来驱动，然而有时，为了手术操作方便，可能会牺牲理想的种植体位置，从而增加修复的复杂性。利用标准的种植体印模组件和简单的临床步骤，制作了一个采用新颖设计的修复体，用于修复两颗紧邻且相互靠拢的种植体。由于无法使用角度螺丝通道技术，制作了一个定制的铸造“支托”基台和其上的套筒冠，以便于进行口腔卫生维护，并根据需要实现可取出性。该病例设计的复杂性转移到了制作的实验室阶段。对于最初具有挑战性的种植体情况，该病例呈现了令人满意的临床结果，并进一步强调了与实验室技术人员密切合作的必要性。
