The aim of this report is to highlight the efficiency of implant restoration of a shortened dental arch (SDA) for a partially edentulous patient.
The SDA refers to a dentition with loss of posterior teeth. The goal of dental care is the maintenance of a natural dentition with regard to esthetics, speech, chewing, and oral comfort. In order to achieve this goal several issues were examined in a SDA clinical scenario including masticatory ability, occlusal factors, the effect of removable partial dentures, oral comfort, and periodontal support.
A 62-year-old female with a SDA presented for treatment with concern about her compromised periodontal and restorative status. Following professional scaling and root planing and oral hygiene motivation, the bite was opened. Restorative treatment was rendered up to the second premolars with the issues associated with a SDA in mind.
A body of evidence in literature showed an arch extending to the second premolars is adequate for normal functional demands, oral hygiene, oral comfort, and possibly reduced costs on a dentition subjected to modern diet. The reported clinical outcomes of using implant supported crowns till the second premolar area using the concept of restoring only an existing SDA were highly satisfactory for the well-oriented patient.
本报告旨在强调为部分牙列缺损患者进行短牙弓（SDA）种植修复的有效性。
SDA是指后牙缺失的牙列。口腔护理的目标是在美观、言语、咀嚼和口腔舒适度方面维持天然牙列。为了实现这一目标，在SDA临床场景中研究了几个问题，包括咀嚼能力、咬合因素、可摘局部义齿的影响、口腔舒适度和牙周支持。
一名患有SDA的62岁女性因担心其牙周和修复状况受损前来治疗。在进行专业的龈上洁治和根面平整以及口腔卫生宣教后，打开咬合。在考虑到SDA相关问题的情况下，对第二前磨牙之前的牙齿进行了修复治疗。
文献中的大量证据表明，对于接受现代饮食的牙列，延伸至第二前磨牙的牙弓足以满足正常功能需求、口腔卫生、口腔舒适度，并可能降低成本。对于目标明确的患者，使用仅修复现有SDA的概念将种植支持冠修复至第二前磨牙区域的报告临床结果非常令人满意。
