The loss of mandibular continuity leads to difficulty in swallowing, problems in mastication, altered mandibular movement, impaired speech articulation, and cosmetic disfigurement. Rehabilitation of such patients becomes more challenging in the case of complete edentulous maxillary and mandibular arches due to a lack of support and anchorage. This case report describes prosthetic rehabilitation of completely edentulous arches with segmental mandibulectomy. Hence, the anchorage was provided with the help of osseointegrated implants in both the maxillary and mandibular arches. Deviation of the mandible toward the unresected side during mastication and other functions was corrected using a palatal ramp. An attempt was made for prosthetic rehabilitation of mandibulectomy defect which required a multidisciplinary approach and which fulfilled the patient's requirement of mastication.
下颌连续性丧失会导致吞咽困难、咀嚼问题、下颌运动改变、言语清晰度受损以及容貌毁损。对于全口无牙的上颌和下颌牙弓患者,由于缺乏支持和固位,此类患者的康复变得更具挑战性。本病例报告描述了行节段性下颌骨切除术的全口无牙牙弓的修复。因此,通过在上颌和下颌牙弓中植入骨整合种植体来提供固位。使用腭隆突矫正咀嚼及其他功能时下颌向未切除侧的偏斜。尝试对下颌骨切除术缺损进行修复,这需要多学科方法并满足患者的咀嚼需求。
