Digital tools such as facial and intraoral digitizers and additive manufacturing (AM) technologies assist restorative treatments. The objective of the present manuscript was to describe a workflow procedure for treatment planning and fabricating a fiber-reinforced composite fixed dental prosthesis (FDP) replacing an absent maxillary lateral incisor, using additively manufactured silicone indices to facilitate the clinical intervention.
The elaboration of a direct fiber-reinforced composite restoration is a technique sensitive procedure which might be time-consuming for the clinician. The digital waxing helped to determine the exact position and size of the lingual wings and connectors of the fiber-reinforced FDP and to design a three-piece index. And the AM of the index helped to transfer the information to the patient's dentition accurately.
The protocol minimizes the time of clinical intervention by facilitating the transference of the virtual diagnostic waxing teeth into the patient's mouth. The three-piece silicone index provides an individualized path of insertion of each index part while also providing a customized space and location of the lingual wings of the restoration.
The usage of AM silicone indices facilitates the clinical intervention by translating the size and position of the diagnostic wax-up teeth into the patient's mouth, minimizing clinical procedure's time.
面部和口内数字化仪以及增材制造 (AM) 技术等数字工具可辅助修复治疗。本研究旨在描述一种使用增材制造硅橡胶印模来辅助临床操作的治疗计划和制作纤维增强复合固定义齿 (FDP) 以替代上颌侧切牙的工作流程。
直接纤维增强型复合修复体的制作是一项对临床医生技术要求较高且耗时的技术。数字化蜡型有助于确定纤维增强 FDP 的舌侧翼和连接体的确切位置和大小,并设计三件式印模。硅橡胶印模的增材制造有助于将信息准确地转移到患者的牙列上。
该方案通过将虚拟诊断蜡型转移到患者口腔中,最大限度地减少了临床干预的时间。三件式硅橡胶印模为每个印模部分的插入提供了个体化的路径,同时还为修复体的舌侧翼提供了定制的空间和位置。
使用 AM 硅橡胶印模通过将诊断蜡型牙齿的大小和位置转化到患者口腔中,从而简化了临床操作,最大限度地减少了临床操作的时间。
