The interarch space is defined as the vertical space between the edentulous ridge and the occlusal or incisal aspect of the opposing arch. Measuring the interarch space in a patient requiring an implant-supported fixed prosthesis is crucial for determining the prostheses to be used in each clinical situation. Depending on the measurements and other factors, such as the need for lip support or pink esthetics issues, decisions about the most convenient type of implant-supported prosthesis can be taken. Analogic workflow to measure the interarch space can represent a time-consuming and expensive procedure that may lead to inaccuracies.
To describe a step-by-step protocol to measure the upper and lower interarch space with open-access software, starting from the digital scan of the patient's complete dentures obtained with an intraoral scanner.
An extraoral scan (using an intraoral scanner) of the existing complete removable prosthesis is required to assess the interarch space for making an implant-supported prosthesis treatment planning. If the existing complete denture does not fulfill the required functional and esthetic parameters, a complete interim denture, a wax trial denture, or a printed denture prototype should be previously fabricated. The antagonist arch and the intermaxillary record scan also need to be obtained. Finally, all STL files are imported into an open-access software for measuring the interarch space.
Open-source software can be used to measure the upper and lower interarch space from existing complete dentures following the step-by-step protocol outlined in this paper.
Interarch space of edentulous patients rehabilitated with complete dentures can be measured with a 360 degrees scanning of the existing complete denture and open-access software by applying the protocol outlined in this paper.
The clinician can assess and digitally measure the interarch space of edentulous patients requiring an implant-supported fixed prosthesis using an open access software.
牙弓间空间是指无牙颌牙槽嵴与对颌牙的咬合或切端之间的垂直空间。在需要种植体支持固定修复体的患者中测量牙弓间空间对于确定每个临床情况下使用的修复体至关重要。根据测量结果和其他因素，如唇支撑的需要或粉红色美学问题，可以决定最方便的种植体支持修复体类型。模拟工作流程来测量牙弓间空间可能是一个耗时且昂贵的过程，并且可能导致不准确。
描述一种使用开放获取软件从患者的全口义齿的数字扫描开始测量上下牙弓间空间的分步协议。
需要对现有的全口可摘义齿进行口外扫描（使用口内扫描仪），以评估用于制作种植体支持修复体治疗计划的牙弓间空间。如果现有的全口义齿不符合所需的功能和美学参数，则应事先制作完整的临时义齿、蜡试义齿或印刷义齿原型。还需要获得对颌弓和颌间记录扫描。最后，将所有 STL 文件导入到开放获取软件中以测量牙弓间空间。
可以使用开源软件按照本文概述的分步协议从现有的全口义齿测量上下牙弓间空间。
使用现有的全口义齿进行 360 度扫描并应用本文概述的协议，使用开放获取软件可以测量用全口义齿修复的无牙颌患者的牙弓间空间。
临床医生可以使用开放访问软件评估和数字测量需要种植体支持固定修复体的无牙颌患者的牙弓间空间。
