Successful management requires a robust diagnosis and treatment planning process. This case report highlights the use of 3D printing to aid the treatment planning of a patient with bilateral unerupted maxillary central incisors due to two supernumerary teeth acting as a physical obstruction. The preoperative cone beam computed tomography scan allowed for production of the printed model to the exact size and dimensions of the unerupted teeth and supernumeraries to facilitate the planning of the case and to aid in consenting the patient for treatment. <\/jats:p>","DOI":"10.1177\/1465312520978984","type":"journal-article","created":{"date-parts":[[2020,12,16]],"date-time":"2020-12-16T17:52:55Z","timestamp":1608141175000},"page":"183-189","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":3,"title":["Use of 3D printing in the planning of a patient with unerupted maxillary central incisors"],"prefix":"10.1177","volume":"48","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6011-8789","authenticated-orcid":false,"given":"Julian Ramesh","family":"Joseph","sequence":"first","affiliation":[{"name":"Cardiff and Vale University Health Board, Cardiff, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sarah","family":"Merrett","sequence":"additional","affiliation":[{"name":"Cardiff and Vale University Health Board, Cardiff, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sheelagh","family":"Rogers","sequence":"additional","affiliation":[{"name":"Cardiff and Vale University Health Board, Cardiff, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Paul","family":"Clark","sequence":"additional","affiliation":[{"name":"Cardiff and Vale University Health Board, Cardiff, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2020,12,16]]},"reference":[{"key":"bibr1-1465312520978984","doi-asserted-by":"publisher","DOI":"10.1177\/1465312519840035"},{"key":"bibr2-1465312520978984","doi-asserted-by":"publisher","DOI":"10.5005\/jp-journals-10005-1534"},{"key":"bibr3-1465312520978984","doi-asserted-by":"publisher","DOI":"10.1016\/j.ajodo.2016.04.018"},{"key":"bibr4-1465312520978984","doi-asserted-by":"publisher","DOI":"10.1016\/j.ajodo.2014.11.019"},{"key":"bibr5-1465312520978984","doi-asserted-by":"publisher","DOI":"10.1177\/1465312519891738"},{"key":"bibr6-1465312520978984","doi-asserted-by":"publisher","DOI":"10.1016\/j.dental.2015.07.005"},{"key":"bibr7-1465312520978984","doi-asserted-by":"publisher","DOI":"10.5114\/kitp.2016.62625"},{"key":"bibr8-1465312520978984","unstructured":"Horner K, Eaton K (2018) Selection Criteria for Dental Radiography.
