Aim: The present in vitro study investigated the dimensional changes of 3D surgical guides printed in-house using Shining 3D surgical guide resin (SG01). Materials and methods: Five test bodies, varying in shape and dimensions, were designed using computer-aided design (CAD) software and manufactured using three different Light Crystal Display (LCD) 3D printers (AccuFab-L4D, Elegoo Mars Pro 3, and Zortrax Inspire). Specific printing and post-processing parameters for the SG01 resin were set to produce 25 test bodies (5 of each shape) from each of the three printers, resulting in a total of 75 samples. The dimensional changes were evaluated using a digital calliper at four different time points: immediately after printing (T0), one month after storage (T1), immediately after sterilization (T2), and one month after sterilization (T3). Results: All the test bodies showed deviations from the overall CAD reference value of 12.25 mm after printing and post-processing (T0) and following steam sterilization (T2). Similar trends were observed for the effect of storage times at T1 and T3. The AccuFab prints demonstrated a better dimensional stability than the Elegoo and Zortrax samples. Conclusions: The LCD 3D printers, sterilization, and storage times influenced the dimensional stability of the test bodies made with SGO1 resin.<\/jats:p>","DOI":"10.3390\/ma18030474","type":"journal-article","created":{"date-parts":[[2025,1,21]],"date-time":"2025-01-21T05:47:42Z","timestamp":1737438462000},"page":"474","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["The Effects of Light Crystal Display 3D Printers, Storage Time and Steam Sterilization on the Dimensional Stability of a Photopolymer Resin for Surgical Guides: An In Vitro Study"],"prefix":"10.3390","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4095-0900","authenticated-orcid":false,"given":"Nicola","family":"Pranno","sequence":"first","affiliation":[{"name":"Department of Oral and Maxillo-Facial Sciences, Sapienza, University of Rome, 6 Caserta Street, 00161 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7679-6776","authenticated-orcid":false,"given":"Alessio","family":"Franchina","sequence":"additional","affiliation":[{"name":"Indipendent Researcher, 44 Legione Gallieno Street, 36100 Vicenza, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7922-8870","authenticated-orcid":false,"given":"Francesca","family":"De Angelis","sequence":"additional","affiliation":[{"name":"Department of Oral and Maxillo-Facial Sciences, Sapienza, University of Rome, 6 Caserta Street, 00161 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maurizio","family":"Boss\u00f9","sequence":"additional","affiliation":[{"name":"Department of Oral and Maxillo-Facial Sciences, Sapienza, University of Rome, 6 Caserta Street, 00161 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alessandro","family":"Salucci","sequence":"additional","affiliation":[{"name":"Department of Oral and Maxillo-Facial Sciences, Sapienza, University of Rome, 6 Caserta Street, 00161 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7654-482X","authenticated-orcid":false,"given":"Edoardo","family":"Brauner","sequence":"additional","affiliation":[{"name":"Department of Oral and Maxillo-Facial Sciences, Sapienza, University of Rome, 6 Caserta Street, 00161 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7583-7030","authenticated-orcid":false,"given":"Maria Paola","family":"Cristalli","sequence":"additional","affiliation":[{"name":"Department of Oral and Maxillo-Facial Sciences, Sapienza, University of Rome, 6 Caserta Street, 00161 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6537-7050","authenticated-orcid":false,"given":"Gerardo","family":"La Monaca","sequence":"additional","affiliation":[{"name":"Department of Oral and Maxillo-Facial Sciences, Sapienza, University of Rome, 6 Caserta Street, 00161 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,1,21]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"121","DOI":"10.1111\/prd.12175","article-title":"Current state of the art of computer-guided implant surgery","volume":"73","author":"Ackhurst","year":"2017","journal-title":"Periodontol. 2000"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"416","DOI":"10.1111\/clr.13346","article-title":"The accuracy of static computer-aided implant surgery: A systematic review and meta-analysis","volume":"29","author":"Tahmaseb","year":"2018","journal-title":"Clin.
