Abstract

The primary reasons for splinting and stabilizing teeth are to connect them for the purpose of replacing missing teeth or as an adjunct to periodontal therapy. Although the restorations must be planned to withstand the functional requirements of occlusion and mastication, esthetic considerations must also be taken into account. The challenge in creating an esthetic result with fiber-reinforced composite splints is that there is limited space in the connector region to create the three-dimensional effect required to give teeth the appearance of individuality. Careful planning in the diagnosis and treatment of the fiber splint is essential to allow for adequate tooth preparation to give the illusion of nonsplinted teeth. When missing teeth are replaced with a fiber-reinforced, direct, fixed partial denture, the pontic must be created to achieve an esthetically pleasing result.

摘要

固定和稳定牙齿的主要原因是将它们连接起来，用于替代缺失的牙齿，或作为牙周治疗的辅助手段。尽管修复体的设计必须能够承受咬合和咀嚼的功能需求，但美学因素也必须加以考虑。使用纤维增强复合材料夹板获得美学效果面临的挑战在于，连接区域的空间有限，难以营造出使牙齿呈现出个性外观所需的三维效果。在纤维夹板的诊断和治疗中进行仔细规划，对于进行充分的牙齿预备以营造非夹板固定牙齿的假象至关重要。当用纤维增强的直接固定局部义齿替代缺失牙齿时，必须制作桥体以获得美观的效果。
