The aim of this study was to examine the accuracy of selective laser melted PSIs (patient-specific implants) and navigation in primary orbital reconstruction. Ninety-six patients with orbital fractures were included in this study. Planned vs. achieved orbital volumes (a) and angles (b) were compared to the unaffected side (n = 96). The analysis included the overlay of post-treatment on planned images (iPlan 3.0.5, Brainlab\u00ae, Feldkirchen, Germany). The mean difference in orbital volume between the digitally planned orbit and the postoperative orbit was 29.16 cm3 (SD 3.54, presurgical) to 28.33 cm3 (SD 3.64, postsurgical, t = 5.00, df = 95.00; p &lt; 0.001), resulting in a mean volume difference (planned vs. postop) of less than 1 cm3. A 3D analysis of the color mapping showed minor deviations compared to the mirrored unaffected side. The results suggested that primary reconstruction in complex orbital wall fractures can be routinely achieved with a high degree of accuracy by using selective laser melted orbital PSIs.<\/jats:p>","DOI":"10.3390\/jcm11123361","type":"journal-article","created":{"date-parts":[[2022,6,12]],"date-time":"2022-06-12T09:26:48Z","timestamp":1655026008000},"page":"3361","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":16,"title":["Primary Orbital Reconstruction with Selective Laser Melting (SLM) of Patient-Specific Implants (PSIs): An Overview of 96 Surgically Treated Patients"],"prefix":"10.3390","volume":"11","author":[{"given":"Majeed","family":"Rana","sequence":"first","affiliation":[{"name":"Department of Oral and Maxillofacial Surgery, Heinrich Heine University Duesseldorf, Moorenstrasse 5, 40225 Duesseldorf, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1040-8814","authenticated-orcid":false,"given":"Henriette L.","family":"Moellmann","sequence":"additional","affiliation":[{"name":"Department of Oral and Maxillofacial Surgery, Heinrich Heine University Duesseldorf, Moorenstrasse 5, 40225 Duesseldorf, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4301-0693","authenticated-orcid":false,"given":"Lara","family":"Schorn","sequence":"additional","affiliation":[{"name":"Department of Oral and Maxillofacial Surgery, Heinrich Heine University Duesseldorf, Moorenstrasse 5, 40225 Duesseldorf, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8470-6478","authenticated-orcid":false,"given":"Julian","family":"Lommen","sequence":"additional","affiliation":[{"name":"Department of Oral and Maxillofacial Surgery, Heinrich Heine University Duesseldorf, Moorenstrasse 5, 40225 Duesseldorf, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Madiha","family":"Rana","sequence":"additional","affiliation":[{"name":"Department of Psychology, University of Applied Sciences, Doberaner Weg 20, 22143 Hamburg, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Max","family":"Wilkat","sequence":"additional","affiliation":[{"name":"Department of Oral and Maxillofacial Surgery, Heinrich Heine University Duesseldorf, Moorenstrasse 5, 40225 Duesseldorf, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3996-7844","authenticated-orcid":false,"given":"Karsten","family":"Hufendiek","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology, Hannover Medical School, Carl-Neuberg-Strasse 1, 30625 Hannover, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,6,11]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"726","DOI":"10.1097\/00001665-200211000-00002","article-title":"Classification and surgical management of orbital fractures: Experience with 111 orbital reconstructions","volume":"13","author":"Manolidis","year":"2002","journal-title":"J.
