When fabricating a removable dental prosthesis, it is unclear if the information received by the dental laboratory technician is clear and sufficient.
The purpose of this survey study was to evaluate the dentist's work authorizations for removable prostheses as well as determine common practices used by laboratories during the fabrication of removable prostheses.
A 24-item questionnaire was developed based on previously published questionnaires and incorporating new topics. A public uniform resource locator (URL) survey link was generated and sent to the office of the Oregon Association of Dental Laboratories (OADL). The executive director of the board then sent out the link to 163 participants that included members and nonmembers of the OADL who were still active in the state of Oregon. Two reminder e-mails were sent 2 weeks apart. Study data were collected and managed by using the Research Electronic Data Capture (REDCap) software program. Descriptive statistics were tabulated, and responses displayed as a percentage of the total.
From the 163 invited participants, 26 responded to the survey representing a 15.9% response rate. Only 11% of the laboratories stated that they routinely receive work authorizations with clear instructions. All participants stated that they always (62.5%) or frequently (37.5%) design the partial prostheses frameworks. Only 37.5% of the laboratories stated that they usually receive adequately extended and accurate definitive casts to fabricate the framework. Fifty percent of the laboratories stated that they very rarely perform altered cast procedures and 50% indicated that half or more of the removable partial prostheses they fabricate were entirely made of acrylic resin. Most laboratories stated that thermoplastic resin partial dentures were less than 25% of their produced volume of removable prostheses. Only 22% of respondents stated that they usually receive adequate information to complete a denture tooth arrangement and most (78%) dentists do not routinely specify the type of occlusal scheme desired for their complete denture tooth arrangements. In most prostheses (77%), posterior palatal seal was marked by the prescribing dentists rarely or very rarely.
Work authorizations provided by the dentists were less than adequate and left much decision-making to the dental laboratory technician.
在制作可摘义齿时，不清楚牙医提供给牙科技师的信息是否清晰、充分。
本调查研究的目的是评估牙医对可摘义齿的工作授权，并确定实验室在制作可摘义齿时的常见做法。
根据之前发表的调查问卷和新纳入的主题制定了 24 项调查问卷。生成一个公共统一资源定位符（URL）调查链接，并发送到俄勒冈州牙科实验室协会（OADL）的办公室。董事会的执行董事随后向俄勒冈州仍活跃的 163 名参与者（包括 OADL 的成员和非成员）发送了链接。两周后发送了两封提醒电子邮件。通过使用 Research Electronic Data Capture（REDCap）软件程序收集和管理研究数据。将描述性统计数据制成表格，并以总回答的百分比形式显示。
在 163 名受邀参与者中，有 26 名回应了调查，回应率为 15.9%。只有 11%的实验室表示他们经常收到有明确说明的工作授权。所有参与者都表示，他们总是（62.5%）或经常（37.5%）设计部分义齿框架。只有 37.5%的实验室表示，他们通常会收到足够延伸和准确的最终模型来制作框架。50%的实验室表示，他们很少进行修改模型的程序，50%表示他们制作的可摘局部义齿有一半或更多是由丙烯酸树脂制成的。大多数实验室表示，热塑性树脂局部义齿占他们制作的可摘义齿体积的不到 25%。只有 22%的受访者表示，他们通常会收到足够的信息来完成义齿牙列排列，并且大多数（78%）牙医不会常规指定他们的全口义齿牙列排列所需的咬合方案类型。在大多数义齿中（77%），后腭部封条很少或几乎不被处方医生标记。
牙医提供的工作授权不足，留给牙科技师很多决策空间。
