Abstract
In-house aligner systems (IHAs), alternatively known as in-office aligners (IOA),
in the strictest sense, refer to clear aligner systems wherein every aspect of the
aligner fabrication from digital treatment planning (DTP) to the delivery of the orthodontic
care is managed in the orthodontic office itself. Although still in its nascent stages,
increased accessibility to chairside intra-oral scanners and office-based 3D printers,
rapid advances in DTP software and aligner fabrication materials, have all helped
the cost-effective concept of fabricating aligners in orthodontic offices, take a
definite shape. The aim of this paper is to elaborate on the essential components
of an IHA system and elucidate a systematic workflow for seamless in-house clear aligner
fabrication with an emphasis on clinical reproducibility, along with a clinical illustration
of a patient treated with IHAs. The authors believe that the development of a standard
operating protocol for in-house clear aligner systems may help reduce the heterogeneity
associated with IHA fabrication and subsequently allow meaningful comparisons with
established commercial clear aligner systems of the day.
