As an alternative to a conventional fixed partial denture, a modification of the hybrid resin-bonded bridge was used to compensate for a spatial discrepancy accentuated by a missing tooth. The proximal margins of the restoration were extended onto the facial surfaces of the abutment teeth to create a partially veneered surface. The abutment teeth were widened by shifting the embrasure into the edentulous space, thus creating more esthetic proportions.
作为传统固定局部义齿的替代方案，采用改良的混合树脂粘结桥来补偿因牙齿缺失而加剧的空间差异。修复体的近中边缘延伸至基牙的颊面，以形成部分贴面的表面。通过将牙间隙移至无牙间隙来加宽基牙，从而创造出更美观的比例。
