Probing depth (PD), clinical attachment level (CAL), and gingival recession (REC) were examined at baseline and 1 year post surgery. The distance between the base of the defect and the cementoenamel junction (BD\u2013CEJ) were measured on periapical radiographs. Gingival volume and thickness were assessed with digital intraoral scans. Linear regression identified factors influencing CAL gain, PD reduction, and bone gain (\u0394BD\u2013CEJ).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      One year post surgery, CAL increased by 2.48\u00a0\u00b1\u00a01.72\u00a0mm (\n                      <jats:italic>p\u00a0<\/jats:italic>\n                      &lt;\u00a00.001), PD reduced by 2.90\u00a0\u00b1\u00a01.40\u00a0mm (\n                      <jats:italic>p\u00a0<\/jats:italic>\n                      &lt;\u00a00.001), and bone gain was 2.46\u00a0\u00b1\u00a01.71\u00a0mm (\n                      <jats:italic>p\u00a0<\/jats:italic>\n                      &lt;\u00a00.001).

The treatment involved using a specially prepared bone graft material (CGF sticky bone) along with a collagen membrane and a CGF membrane. The researchers tracked the changes in gum and bone health in 13 patients with 31 shallow defects over 1 year. The results showed significant improvements: Gum attachment levels increased by an average of 2.48\u00a0mm, gum pockets reduced by 2.90\u00a0mm, and bone growth averaged 2.46\u00a0mm. Notably, gum recession and gingival contour remained stable, meaning the treatment did not compromise the appearance of the gums. The study also found that patients with worse gum or bone loss at the start of the treatment tended to experience the greatest improvements. These findings suggest that CGF sticky bone combined with GTR is a promising option for restoring shallow bone defects, particularly in cases where traditional therapy has left residual gum pockets.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1002\/jper.24-0728","type":"journal-article","created":{"date-parts":[[2025,5,19]],"date-time":"2025-05-19T11:04:54Z","timestamp":1747652694000},"page":"11-22","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Concentrated growth factor with guided tissue regeneration for shallow infrabony defects: A one\u2010year prospective study"],"prefix":"10.1002","volume":"97","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5004-4667","authenticated-orcid":false,"given":"Siniong","family":"Iao","sequence":"first","affiliation":[{"name":"Department of Periodontology Peking University School and Hospital of Stomatology &amp; National Center for Stomatology &amp; National Clinical Research Center for Oral Diseases &amp; National Engineering Research Center of Oral Biomaterials and Digital Medical Devices  Beijing China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3703-0847","authenticated-orcid":false,"given":"Xiangying","family":"Ouyang","sequence":"additional","affiliation":[{"name":"Department of Periodontology Peking University School and Hospital of Stomatology &amp; National Center for Stomatology &amp; National Clinical Research Center for Oral Diseases &amp; National Engineering Research Center of Oral Biomaterials and Digital Medical Devices  Beijing China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0003-9166-1225","authenticated-orcid":false,"given":"Yan","family":"Huang","sequence":"additional","affiliation":[{"name":"Department of Periodontology Peking University School and Hospital of Stomatology &amp; National Center for Stomatology &amp; National Clinical Research Center for Oral Diseases &amp; National Engineering Research Center of Oral Biomaterials and Digital Medical Devices  Beijing China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jianru","family":"Liu","sequence":"additional","affiliation":[{"name":"Department of Periodontology Peking University School and Hospital of Stomatology &amp; National Center for Stomatology &amp; National Clinical Research Center for Oral Diseases &amp; National Engineering Research Center of Oral Biomaterials and Digital Medical Devices  Beijing China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wenyi","family":"Liu","sequence":"additional","affiliation":[{"name":"Department of Periodontology Peking University School and Hospital of Stomatology &amp; National Center for Stomatology &amp; National Clinical Research Center for Oral Diseases &amp; National Engineering Research Center of Oral Biomaterials and Digital Medical Devices  Beijing China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2025,5,19]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-051X.1980.tb01962.x"},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.1902\/jop.1984.55.3.149"},{"key":"e_1_2_9_4_1","doi-asserted-by":"publisher","DOI":"10.1080\/00016357.2016.1265665"},{"key":"e_1_2_9_5_1","doi-asserted-by":"publisher","DOI":"10.1034\/j.1600-051X.29.s3.5.x"},{"key":"e_1_2_9_6_1","doi-asserted-by":"publisher","DOI":"10.1111\/idh.12688"},{"key":"e_1_2_9_7_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-051X.2008.01245.x"},{"key":"e_1_2_9_8_1","doi-asserted-by":"publisher","DOI":"10.1902\/jop.2015.130685"},{"key":"e_1_2_9_9_1","doi-asserted-by":"publisher","DOI":"10.1034\/j.1600-0757.2000.2220106.x"},{"key":"e_1_2_9_10_1","doi-asserted-by":"publisher","DOI":"10.1111\/jcpe.13281"},{"key":"e_1_2_9_11_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-051X.1998.tb02402.x"},{"key":"e_1_2_9_12_1","doi-asserted-by":"publisher","DOI":"10.1034\/j.1600-051X.1997.00833.x"},{"key":"e_1_2_9_13_1","doi-asserted-by":"publisher","DOI":"10.1902\/jop.2001.72.12.1639"},{"key":"e_1_2_9_14_1","doi-asserted-by":"publisher","DOI":"10.1902\/jop.2005.76.8.1354"},{"key":"e_1_2_9_15_1","doi-asserted-by":"publisher","DOI":"10.1111\/prd.12048"},{"key":"e_1_2_9_16_1","first-page":"740","article-title":"[Past and present of plasmatrix]","volume":"56","author":"Zhang YF","year":"2021","journal-title":"Zhonghua Kou Qiang Yi Xue Za Zhi"},{"key":"e_1_2_9_17_1","first-page":"255","article-title":"Do autologous platelet concentrates (APCs) have a role in intra\u2010oral bone regeneration?
