As life expectancy increases, a larger number of elderly people require dental health care attention for implant-supported rehabilitation, with the aim of restoring the function and aesthetics of the oral cavity. Most of these patients have lost their teeth long time ago, causing a severe bone resorption and maxillary sinus pneumatization. Therefore, the current study aims to demonstrate, through the description of the clinical case, the treatment with zygomatic implants as an option for treating severely atrophic maxillas. In this clinical study, the patient presented, in the clinical and image evaluation, severe alveolar bone atrophy, with height and thickness loss, in addition to a high-level pneumatization of the maxillary sinus, bilaterally. The classical zygomatic fixation technique was suggested, with 2 anterior conventional implants and 2 zygomatic implants in the posterior region with the placement of implant-supported prosthesis with immediate loading. The patient was monitored for 7 years and did not present pain complaints, absence of infection, or implant loss. Based on this clinical case study, it was concluded that the zygomatic implants are satisfactory options to aid the implant-supported rehabilitation of atrophic maxillas.
随着预期寿命的增加，越来越多的老年人需要种植牙支持的修复治疗来关注口腔健康，目的是恢复口腔的功能和美观。这些患者大多早已失牙，导致严重的骨吸收和上颌窦气化。因此，本研究旨在通过临床病例描述，展示使用颧骨种植体治疗严重萎缩上颌骨的方法。在这项临床研究中，患者在临床和影像学评估中表现为严重的牙槽骨萎缩，高度和厚度均有丧失，此外双侧上颌窦气化程度较高。建议采用经典的颧骨固定技术，在前部植入2颗传统种植体，在后部植入2颗颧骨种植体，并立即加载种植体支持的假体。对患者进行了7年的监测，患者未出现疼痛主诉、感染或种植体丢失。基于该临床病例研究，得出结论：颧骨种植体是帮助萎缩上颌骨进行种植体支持修复的令人满意的选择。
