The occlusion of a complete dental arch is generally desirable but not necessary nor always achievable in many individuals. It is, however, relevant for dentists to consider what minimum number of teeth is required by individuals for oral function. This study investigated dentists' awareness and opinion of the shortened dental arch (SDA) concept in an Australian context.
A self-administered voluntary and anonymous questionnaire was mailed to a sample of 434 dentists, randomly selected from both rural and metropolitan locations in Victoria, Australia. The information collected included awareness of the SDA concept and its application as a treatment option.
More than half of the respondents (61%) were aware of the SDA concept. All respondents 'agreed' or 'strongly agreed' with the seven criteria of SDA proposed in this study based on Käyser (1989). The majority (78.4%) believed that the SDA concept is useful in clinical practice. Dentists with <20 years of experience expressed more awareness compared to others (χ(2) test, p = 0.004).
Most dentists who responded to this survey agreed that the SDA is a practical and useful treatment modality for older adults with limitations to complex restorative care. However, application of the SDA varied considerably among dentists.
完整牙弓的咬合通常是理想的，但在许多个体中并非必要，也并非总能实现。然而，对于牙医来说，考虑个体口腔功能所需的最少牙齿数量是很有必要的。本研究在澳大利亚背景下调查了牙医对短牙弓（SDA）概念的认识和看法。
向从澳大利亚维多利亚州农村和城市地区随机抽取的434名牙医样本邮寄了一份自我填写的自愿且匿名问卷。收集的信息包括对SDA概念的认识及其作为一种治疗选择的应用情况。
超过一半的受访者（61%）了解SDA概念。所有受访者“同意”或“强烈同意”本研究基于凯泽（1989年）提出的SDA的七条标准。大多数人（78.4%）认为SDA概念在临床实践中有用。与其他牙医相比，经验不足20年的牙医表现出更高的认知度（χ²检验，p = 0.004）。
参与本次调查的大多数牙医都认为，对于复杂修复治疗受限的老年人，SDA是一种实用且有效的治疗方式。然而，SDA在牙医中的应用差异很大。
