This study investigated the impact of orthodontic plaster models on orthodontic diagnosis and treatment planning decisions by orthodontists. Methods: Thirty-three orthodontists assessed six patients\u2019 records with different malocclusion cases. Each case was assessed twice by each orthodontist evaluating a case: the first evaluation with digital records without diagnostic casts and the second evaluation with the added diagnostic orthodontic plaster model. Diagnostic and treatment plan decisions for each malocclusion case were compared with and without the aid of the diagnostic orthodontic plaster models to assess the plaster model\u2019s impact on the treatment plan\u2019s soundness. Results: Statistically insignificant differences were found for the diagnoses and treatment plans with or without the aid of orthodontic plaster models. Intraclass correlation coefficients revealed agreement among orthodontists for both evaluated situations (0.685; p &lt; 0.0001). Plaster models were found to significantly influence orthodontists\u2019 decisions about the need for surgical intervention (p = 0.026), but they did not significantly impact the overall malocclusion diagnostic classification nor the decision regarding the extent of treatment, whether comprehensive or limited (p = 0.146) and extraction versus non-extraction approaches (p = 0.266). Conclusions: These findings support the idea that digital record alternatives may be viable for orthodontic recordkeeping purposes. Within the limitations of this study, it can be concluded that the presence or absence of orthodontic plaster models does not significantly impact the orthodontic diagnosis or treatment planning process.<\/jats:p>","DOI":"10.3390\/diagnostics14192124","type":"journal-article","created":{"date-parts":[[2024,9,25]],"date-time":"2024-09-25T04:01:24Z","timestamp":1727236884000},"page":"2124","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["The Efficacy of Diagnostic Plaster Models in Orthodontic Diagnosis and Treatment Planning"],"prefix":"10.3390","volume":"14","author":[{"given":"Abdullazez","family":"Almudhi","sequence":"first","affiliation":[{"name":"Department of Pediatric Dentistry and Orthodontics, College of Dentistry, King Saud University, Riyadh 11545, Saudi Arabia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Iman","family":"Almohammad","sequence":"additional","affiliation":[{"name":"College of Dentistry, King Saud University, Riyadh 11545, Saudi Arabia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sara","family":"Alswayyed","sequence":"additional","affiliation":[{"name":"College of Dentistry, King Saud University, Riyadh 11545, Saudi Arabia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3592-4177","authenticated-orcid":false,"given":"Elzahraa","family":"Eldwakhly","sequence":"additional","affiliation":[{"name":"Department of Clinical Dental Sciences, College of Dentistry, Princess Nourah bint Abdulrahman University, Riyadh 11671, Saudi Arabia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sarah","family":"Almugairin","sequence":"additional","affiliation":[{"name":"Department of Preventive Dental Sciences, College of Dentistry, Princess Nourah bint Abdulrahman University, Riyadh 11671, Saudi Arabia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,9,25]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"N\u00e9meth, O., Uhrin, E., Girasek, E., Boros, J., and Gy\u0151rffy, Z.
