This case study introduces two protocols for multidisciplinary CEJ reconstruction prior to the root coverage therapy (RCT).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Two patients with GR and NCCLs were treated using two CEJ reconstruction techniques: both, analogically and digitally guided. For each case, the position of the therapeutic CEJ was predetermined using a combination of the methods described by Zucchelli and Cairo. Then, an analog or digital diagnostic wax\u2010up was performed accordingly. In the analogically guided technique, a transparent silicone guide matrix was used to transfer information from the dental wax\u2010up. In contrast, the digitally guided technique employed a rigid, translucent resin prosthetic guide matrix that was designed and printed. Restorations were fabricated using direct composite resin and RCT was performed 1 week later in both techniques.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>At 6 months, both cases demonstrated complete root coverage and effective healing of the soft tissues surrounding the restorations.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Dimensional changes in materials and precise guide adjustment in the analog technique are operator\u2010dependent and can affect the outcomes.

The usage of these two CEJ reconstruction techniques enhances communication within the multidisciplinary team and ensures optimal aesthetic outcomes and precise placement of the gingival margin.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Key points<\/jats:title>\n                    <jats:p>\n                      <jats:list list-type=\"bullet\">\n                        <jats:list-item>\n                          <jats:p>There are no established clinical protocols described in the literature for reconstructing the cemento\u2010enamel junction (CEJ) once the position of a therapeutic CEJ has been predetermined and prior root coverage therapy (RCT).<\/jats:p>\n                        <\/jats:list-item>\n                        <jats:list-item>\n                          <jats:p>Performing a diagnostic wax\u2010up (analogically or digitally) to reconstruct the therapeutic CEJ is crucial and facilitates the creation of a prosthetic guide that accurately reproduces the defined CEJ position.<\/jats:p>\n                        <\/jats:list-item>\n                        <jats:list-item>\n                          <jats:p>The reconstruction of the CEJ may improve the prognosis of RCT.<\/jats:p>\n                        <\/jats:list-item>\n                      <\/jats:list>\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Plain language summary<\/jats:title>\n                    <jats:p>This study looked at a dental issue called non\u2010carious cervical lesions, which happens when the hard tissue near the gum line of a tooth wears away, making it harder to treat gum recession. Two different approaches were tested to rebuild the lost tissue in the gum area before performing a procedure to cover the exposed roots. One approach used traditional methods with physical guides to help place the new tissue, while the other used advanced digital techniques to create a precise guide using 3D printing. After 6 months, both methods successfully covered the exposed roots and helped the gums heal properly. However, the traditional method's results can vary depending on the dentist's skill, while the digital method, although more accurate, can be expensive. Using these methods can improve teamwork among dental specialists and lead to better\u2010looking results by ensuring the gum line is placed exactly where it should be.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1002\/cap.10315","type":"journal-article","created":{"date-parts":[[2024,9,28]],"date-time":"2024-09-28T07:14:14Z","timestamp":1727507654000},"page":"299-311","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Digital and analog techniques for cemento\u2010enamel junction reconstruction: A case study"],"prefix":"10.1002","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8837-2540","authenticated-orcid":false,"given":"Juan Carlos","family":"Dur\u00e1n","sequence":"first","affiliation":[{"name":"Escuela de Odontolog\u00eda Facultad de Medicina Cl\u00ednica Alemana Universidad del Desarrollo  Santiago Chile"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0001-6450-7412","authenticated-orcid":false,"given":"Valeria","family":"G\u00f3mez","sequence":"additional","affiliation":[{"name":"Escuela de Odontolog\u00eda Facultad de Medicina Cl\u00ednica Alemana Universidad del Desarrollo  Santiago Chile"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0003-5504-2419","authenticated-orcid":false,"given":"Cristian","family":"Aguilera","sequence":"additional","affiliation":[{"name":"Escuela de Odontolog\u00eda Facultad de Medicina Cl\u00ednica Alemana Universidad del Desarrollo  Santiago Chile"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0005-6626-1064","authenticated-orcid":false,"given":"Rodrigo","family":"Pino","sequence":"additional","affiliation":[{"name":"Private Practice"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0008-4543-612X","authenticated-orcid":false,"given":"Vasco","family":"S\u00e1iz","sequence":"additional","affiliation":[{"name":"Escuela de Odontolog\u00eda Facultad de Medicina Cl\u00ednica Alemana Universidad del Desarrollo  Santiago Chile"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0005-3120-027X","authenticated-orcid":false,"given":"Nicol\u00e1s","family":"Gonz\u00e1lez","sequence":"additional","affiliation":[{"name":"Escuela de Odontolog\u00eda Facultad de Medicina Cl\u00ednica Alemana Universidad del Desarrollo  Santiago Chile"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0001-1878-8313","authenticated-orcid":false,"given":"Yuri","family":"Cataldo","sequence":"additional","affiliation":[{"name":"Escuela de Odontolog\u00eda Facultad de Medicina Cl\u00ednica Alemana Universidad del Desarrollo  Santiago Chile"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0004-4000-0432","authenticated-orcid":false,"given":"Murir","family":"Gauro","sequence":"additional","affiliation":[{"name":"Escuela de Odontolog\u00eda Facultad de Medicina Cl\u00ednica Alemana Universidad del Desarrollo  Santiago Chile"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6367-0592","authenticated-orcid":false,"given":"Iv\u00e1n","family":"Urz\u00faa","sequence":"additional","affiliation":[{"name":"Escuela de Odontolog\u00eda Facultad de Medicina Cl\u00ednica Alemana Universidad del Desarrollo  Santiago Chile"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1557-4846","authenticated-orcid":false,"given":"Fernando","family":"Solanes","sequence":"additional","affiliation":[{"name":"Private Practice"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0005-8614-6784","authenticated-orcid":false,"given":"Catalina","family":"Madariaga","sequence":"additional","affiliation":[{"name":"Private Practice"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2024,9,28]]},"reference":[{"key":"e_1_2_10_2_1","doi-asserted-by":"publisher","DOI":"10.1111\/jopr.13585"},{"key":"e_1_2_10_3_1","doi-asserted-by":"publisher","DOI":"10.1902\/jop.2010.090631"},{"key":"e_1_2_10_4_1","doi-asserted-by":"publisher","DOI":"10.1902\/jop.2006.050038"},{"issue":"5","key":"e_1_2_10_5_1","first-page":"16","article-title":"Interdisciplinary treatment of cervical lesions","volume":"32","author":"Allen EP","year":"2011","journal-title":"Compend Contin Educ Dent"},{"issue":"6","key":"e_1_2_10_6_1","first-page":"573","article-title":"A technique to identify and reconstruct the cementoenamel junction level using combined periodontal and restorative treatment of gingival recession.
