Removable partial denture production in Scotland was studied by analyzing photographs taken of consecutive casts and dentures and reviewing prescriptions of 539 cases at a large dental laboratory. Of the casts, 70.4% were maxillary and 29.6% mandibular. The mean number of teeth present was 9.9 in the maxilla and 8.4 in the mandible. Of the partial dentures studied, 33.6% were acrylate dentures without any framework. None of these had occlusal rests, and 5.6% had clasps. Of the framework-retained maxillary dentures, the palatal strap (12.9%), horseshoe (15.8%), and anterior palatal bar (18.9%) designs were the most frequent. In the mandible, lingual bars (32.7%) and lingual plates (32.7%) predominated. Of the acrylic dentures, 89.3% were made without any instruction from the dentist. The corresponding figure for prostheses with cobalt-chromium frameworks was 15.0%.
通过分析连续模型和义齿的照片，并查阅一家大型牙科实验室539例病例的处方，对苏格兰可摘局部义齿的制作情况进行了研究。在模型中，70.4%为上颌模型，29.6%为下颌模型。上颌现存牙齿的平均数量为9.9颗，下颌为8.4颗。在所研究的局部义齿中，33.6%为无任何基托的丙烯酸树脂义齿。这些义齿均无支托，5.6%有卡环。在上颌基托固位的义齿中，腭杆（12.9%）、马蹄形（15.8%）和前腭杆（18.9%）设计最为常见。在下颌，舌杆（32.7%）和舌板（32.7%）占主导。在丙烯酸树脂义齿中，89.3%是在没有牙医任何指导的情况下制作的。钴铬合金基托修复体的相应比例为15.0%。
