Background:
The aim of this investigation is to evaluate the feasibility of digital workflow for lingual fixed retainer based on digital intraoral scan and appliance production from Polyetheretherketone (PEEK) material for clinical consideration.
Material And Methods:
Fully virtual lingual retainer with bilateral missing lateral incisors was designed using inlab software (Dentsply Sirona, Pennsylvania, USA). The designed retainer was produced in PEEK material and clinically adhered to lingual surfaces of the lower front teeth.
Results:
Lingual retainer was successfully fabricated by full digital workflow and produced from PEEK material for clinical usage.
Conclusions:
Although full digital workflow can be clinically used for production of prefabricated lingual retainer, however further software adaptions are required for improvement of the orthodontic workflow. Key words:PEEK, CAD/CAM, digital orthodontics, lingual retainer.
