Abstract

The application of immediate loading of implants in the edentulous maxilla in multiple-risk patients is presented. Five partially edentulous patients attended with failing prostheses supported by hopeless teeth. An immediate-loading protocol was proposed because the patients rejected provisionalization with a removable prosthesis. Multiple teeth were extracted, and 44 immediately loaded implants were placed, most of them (55.5% to 88.9%) in fresh extraction sites, to support a cross-arch prosthesis that was loaded 3 to 4 days after surgery. The overall implant failure rate was 13.4%; in healed sites it was 20% (2/10) and in fresh extraction sites it was 8.82% (3/34). Prosthetic success was 100%. The overall failure rate was higher than is usually seen with the standard delayed-loading approach. Nevertheless, this immediate-loading protocol was satisfactory for the patients and the practitioner because prosthetic success was maintained during the provisionalization phase.

摘要

本文介绍了在多风险患者的无牙上颌中即刻加载种植体的应用情况。五名部分牙列缺失患者就诊时，其义齿因患牙预后无望而出现功能障碍。由于患者拒绝使用可摘义齿进行临时修复，因此提出了即刻加载方案。拔除了多颗牙齿，并植入了44颗即刻加载种植体，其中大部分（55.5%至88.9%）植入新鲜拔牙位点，以支持术后3至4天加载的跨牙弓义齿。种植体总体失败率为13.4%；在愈合位点为20%（2/10），在新鲜拔牙位点为8.82%（3/34）。修复成功率为100%。总体失败率高于标准延迟加载方法通常所见的情况。然而，这种即刻加载方案对患者和医生来说是令人满意的，因为在临时修复阶段保持了修复成功。
