Passively retained precision attachment removable partial dentures have been used successfully since the 1920s. Adult cleft palate patients and accident victims often have endured a lifetime of wearing awkward appliances to replace the missing structures that never formed intraorally or were lost in a traumatic accident. These patients tend to be poor candidates for dental implants, even with repeated grafting surgeries. The anterior double-tilt precision attachment case is a great treatment option for adults to restore the missing dental structures. Anterior precision partial dentures are stable appliances in the mouth that are worn 24 hours a day and only removed for hygiene. They can be custom designed for maximum esthetics. They do not require denture paste, and they extend minimally onto the palate. As a result, they do not interfere with musculature, tongue movements, speech and taste. Cleft palate patients and accident victims with poor or non-existent edentulous ridges will have difficulty retaining a denture, so preservation of the existing dentition is essential for comfort and function. Because these prostheses do not apply destructive forces to the abutment teeth, they can last decades with minimal maintenance.
自20世纪20年代以来，被动固位精密附着体可摘局部义齿就已成功应用。成年腭裂患者和事故受害者常常一生都佩戴着笨拙的矫治器，以替代口腔内从未形成或在创伤性事故中缺失的结构。即使经过多次植骨手术，这些患者往往也不是种植牙的理想人选。前牙双倾斜精密附着体病例是成年人修复缺失牙结构的极佳治疗选择。前牙精密局部义齿在口腔中是稳定的矫治器，每天佩戴24小时，仅为了保持口腔卫生才取下。它们可以定制设计以达到最大美观效果。它们不需要义齿膏，并且对上腭的覆盖极小。因此，它们不会干扰肌肉组织、舌头运动、言语和味觉。腭裂患者和无牙嵴状况不佳或不存在的事故受害者在固位义齿方面会有困难，所以保留现有的牙列对于舒适度和功能至关重要。由于这些修复体不会对基牙施加破坏力，它们只需极少的维护就能使用数十年。
