SHORT-TERM AESTHETIC REHABILITATION WITH 3D PRINTED SNAP-ON SMILE DEVICES – LITERATURE REVIEW AND A CASE REPORT

Abstract

Aim of the study The main objective of this paper is to perform an up-to-date literature review of the application and implications of using Snap-On Smile devices for short-term aesthetic rehabilitation, as well as to showcase the 3D printing workflow in manufacturing these devices through a case study. Materials and methods The present systematic study was conducted following the PRISMA-P structure of a systematic review, by using three electronic databases (PubMed, Google Scholar, and EMBASE) to perform a literature search from 2000 to 2024 using the following MESH terms: snap on smile, aesthetic, removable, device. After discarding duplicates, out of 81 results, a total of 6 articles were eligible and included in the review. Results Constructed from durable materials like crystallized acetyl resin or PMMA, the Snap-On Smile offers up to five years of use. Manufactured through advanced techniques such as injection moulding, CAD/CAM milling, or 3D printing, it provides an aesthetic solution without necessitating tooth preparation. The case study of a 59-year-old female illustrates its efficacy in providing immediate aesthetic enhancement for a significant social event. Conclusions The Snap-On Smile has emerged as a significant advancement in aesthetic dentistry, balancing the desire for improved dental aesthetics with the need to preserve natural tooth structures. Its ease of application and non-invasive nature make it a suitable option for many patients, though its limitations necessitate careful consideration in complex cases.
