The generally recommended treatment for patients with mandibular bone atrophy involves extensive bone reconstruction to enable the use of standard dental implants. In posterior areas with limited height and thickness, a combination of wide-short dental implants and long implants has also been recommended. This alternative treatment improves the biomechanical resistance to stress from occlusal forces during mastication and has achieved success rates comparable to those of standard implants. In most cases, this treatment option allows immediate loading, simplifying the oral rehabilitation and decreasing the morbidity rate. The purpose of this case report is to discuss clinical treatment of a patient with bilateral bone atrophy in the posterior regions of the mandible. Two wide-short implants splinted to 1 standard implant were used for rehabilitation on the right side. The mandibular left hemiarch had a greater amount of bone, and 3 standard implants were placed on the right side. One year after implant placement, the treatment outcomes were found to be similar on both sides. In this patient, the use of wide-short implants splinted to a standard implant improved mandibular occlusal stability in an area of reduced bone height.
下颌骨萎缩患者的一般推荐治疗方法包括进行广泛的骨重建,以便能够使用标准牙种植体。在高度和厚度有限的后部区域,也有人推荐使用宽短型牙种植体和长种植体相结合的方法。这种替代治疗方法提高了咀嚼过程中对咬合力应力的生物力学抵抗力,并且成功率与标准种植体相当。在大多数情况下,这种治疗方案允许即刻负重,简化了口腔修复过程并降低了发病率。本病例报告的目的是讨论一名下颌骨后部双侧骨萎缩患者的临床治疗情况。右侧使用了两个宽短型种植体与1个标准种植体进行夹板固定以进行修复。下颌左侧半侧牙弓的骨量较多,右侧植入了3个标准种植体。种植体植入一年后,发现两侧的治疗效果相似。在该患者中,使用与标准种植体进行夹板固定的宽短型种植体改善了骨高度降低区域的下颌咬合稳定性。
