The rehabilitation of edentulous maxillae is a complex procedure due to the involvement of esthetic and functional requirements. A trial maxillary denture can be used to identify the need for adequate upper lip support when replacing removable complete dentures by implant-fixed dental prostheses. This clinical report describes the outcome of the rehabilitation of an edentulous atrophic maxilla with unfavorable maxillomandibular relationship and deficient upper lip support. A trial denture was fabricated and used to diagnose the need for a prosthesis capable of restoring the upper lip support. The reduced upper lip support was also confirmed by a lateral cephalogram. The patient was rehabilitated by an implant-fixed dental prosthesis associated with an attachment-retained gingival prosthesis. The case presented shows that when loss of upper lip support is detected and the patient does not wish to undergo further surgical reconstruction procedure, the retention of a gingival prosthesis using a ball attachment is a satisfactory treatment option.
由于涉及美观和功能需求，无牙上颌骨的修复是一个复杂的过程。当用种植固定义齿替代可摘全口义齿时，上颌试验义齿可用于确定对上唇适当支撑的需求。本临床报告描述了一位上颌骨萎缩、无牙且上下颌关系不良、上唇支撑不足患者的修复结果。制作了一副试验义齿并用于诊断是否需要一副能够恢复上唇支撑的义齿。头颅侧位片也证实了上唇支撑的减少。该患者通过与附着体固位的牙龈义齿相关联的种植固定义齿进行了修复。所呈现的病例表明，当检测到上唇支撑丧失且患者不希望接受进一步的手术重建程序时，使用球附着体保留牙龈义齿是一种令人满意的治疗选择。
