Abstract

Diagnostic imaging acts as a distinctive method in analyzing and drawing in the appropriate treatment protocol for any procedure. Pertaining to immediate implant placement, determining the bone width and height plays a vital role in the success of the implant therapy. This visualization of the measurements done preoperatively will enhance the treatment by reducing the overall time span of the procedure. Currently, cone beam computed tomography (CBCT) plays a significant role in the preoperative determination of the measurements of the tooth and the bone. This case report is regarding, a 27-year-old male patient reporting to the Department of Oral and Maxillofacial Surgery at Madha Dental College and Hospital, with a chief complaint of fractured crown in relation to the upper left front tooth region. On clinical examination, there was the presence of an endodontically failed and fractured crown in relation to 22. With the interpretation of clinical and radiographic examination, the tooth was categorized under unfavorable prognosis. The patient was given a detailed description of the various treatment procedures available pertaining to that present condition, along with immediate implant placement procedure. Since the patient was young and conscious about his esthetics and accuracy, he opted for placement of immediate implant followed by extraction of the tooth. To accurately determine the length and width, the tooth and socket measurements were preoperatively measured by CBCT. This article evaluates the accuracy of CBCT by comparing the clinical quantity of bone and dimensions of tooth to be extracted and alveolar socket.

摘要

诊断成像在分析和制定任何手术的适当治疗方案方面是一种独特的方法。对于即刻种植体植入，确定骨宽度和高度在种植治疗的成功中起着至关重要的作用。术前进行测量的可视化将通过减少手术的总时间跨度来提高治疗效果。目前，锥形束计算机断层扫描（CBCT）在术前确定牙齿和骨的测量方面发挥着重要作用。本病例报告涉及一名27岁男性患者，他前往马达牙科学院和医院口腔颌面外科就诊，主要主诉是左上前牙区冠折。临床检查发现，22号牙存在牙髓治疗失败且冠折的情况。根据临床和影像学检查结果，该牙被归类为预后不良。医生向患者详细介绍了针对当前病情的各种治疗方法，包括即刻种植体植入手术。由于患者年轻且注重美观和精确性，他选择了即刻种植体植入，随后拔除患牙。为了准确确定长度和宽度，术前通过CBCT测量了牙齿和牙槽窝的尺寸。本文通过比较待拔除牙齿和牙槽窝的临床骨量及尺寸与CBCT测量结果，评估了CBCT的准确性。
