Recession defects received a CTG or GTR by random assignment. At baseline (immediately prior to surgery) and 6 and 120 \u00b1 12 months after surgery, clinical parameters were obtained.<\/jats:p><jats:p><jats:bold>Results:<\/jats:bold> Nine patients, who contributed 24 recession defects, were available for re\u2010examination at 120 \u00b1 12 months. Six and 120 \u00b1 12 months after receiving a CTG, statistically significant (<jats:italic>P<\/jats:italic> &lt;0.05) root coverage was observed compared to baseline root coverage (6 months: 3.07 \u00b1 1.74 mm; 120 \u00b1 12 months: 2.07 \u00b1 1.89 mm). The GTR therapy resulted in statistically significant root coverage compared to baseline root coverage only after 6 months (2.28 \u00b1 1.77 mm; <jats:italic>P<\/jats:italic> &lt;0.05). Both groups experienced a statistically significant loss of coverage from 6 to 120 \u00b1 12 months (CTG: \u22121.0 \u00b1 0.78 mm; GTR: \u22122.03 \u00b1 2.24 mm). At 120 \u00b1 12 months after CTG surgery, the stability of root coverage was statistically significantly better than 120 \u00b1 12 months after GTR surgery (<jats:italic>P<\/jats:italic> = 0.002). The CTG caused more post\u2010surgical discomfort (<jats:italic>P<\/jats:italic> &lt;0.05), but it resulted in a better treatment outcome (<jats:italic>P<\/jats:italic> &lt;0.05) than GTR as perceived by patients.<\/jats:p><jats:p><jats:bold>Conclusion:<\/jats:bold> The long\u2010term stability of root coverage (i.e., the reduction of recession depth) and esthetic results perceived by patients were significantly better 10 years after CTG surgery, statistically, than after GTR surgery using bioabsorbable barriers.<\/jats:p>","DOI":"10.1902\/jop.2010.090632","type":"journal-article","created":{"date-parts":[[2010,4,9]],"date-time":"2010-04-09T11:43:23Z","timestamp":1270813403000},"page":"827-836","source":"Crossref","is-referenced-by-count":45,"title":["Ten\u2010Year Results After Connective Tissue Grafts and Guided Tissue Regeneration for Root Coverage"],"prefix":"10.1002","volume":"81","author":[{"given":"Katrin","family":"Nickles","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Petra","family":"Ratka\u2010Kr\u00fcger","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eric","family":"Neukranz","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Peter","family":"Raetzke","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Peter","family":"Eickholz","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2010,6]]},"reference":[{"key":"e_1_2_7_2_1","first-page":"8","article-title":"A classification of marginal tissue recession","volume":"5","author":"Miller PD","year":"1985","journal-title":"Int J Periodontics Restorative Dent"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.1902\/annals.1999.4.1.1"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.1034\/j.1600-051X.29.s3.11.x"},{"key":"e_1_2_7_5_1","doi-asserted-by":"publisher","DOI":"10.1902\/annals.2003.8.1.303"},{"key":"e_1_2_7_6_1","doi-asserted-by":"publisher","DOI":"10.1902\/jop.1985.56.7.397"},{"key":"e_1_2_7_7_1","doi-asserted-by":"publisher","DOI":"10.1902\/jop.1985.56.12.715"},{"key":"e_1_2_7_8_1","doi-asserted-by":"publisher","DOI":"10.1902\/jop.1987.58.2.95"},{"key":"e_1_2_7_9_1","doi-asserted-by":"publisher","DOI":"10.1902\/jop.1992.63.11.919"},{"key":"e_1_2_7_10_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-051X.2008.01267.x"},{"key":"e_1_2_7_11_1","doi-asserted-by":"publisher","DOI":"10.1902\/jop.1996.67.1.7"},{"key":"e_1_2_7_12_1","doi-asserted-by":"publisher","DOI":"10.1902\/jop.1992.63.6.554"},{"key":"e_1_2_7_13_1","doi-asserted-by":"publisher","DOI":"10.1034\/j.1600-051x.2002.290106.x"},{"key":"e_1_2_7_14_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-0765.2007.00971.x"},{"key":"e_1_2_7_15_1","doi-asserted-by":"publisher","DOI":"10.1902\/jop.1997.68.8.779"},{"key":"e_1_2_7_16_1","doi-asserted-by":"publisher","DOI":"10.1902\/jop.2001.72.10.1301"},{"key":"e_1_2_7_17_1","doi-asserted-by":"publisher","DOI":"10.1902\/jop.1998.69.9.975"},{"key":"e_1_2_7_18_1","doi-asserted-by":"publisher","DOI":"10.1902\/jop.1996.67.11.1216"},{"key":"e_1_2_7_19_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-051X.1997.tb01184.x"},{"key":"e_1_2_7_20_1","first-page":"19","article-title":"Long\u2010term root coverage results with connective tissue in the envelope technique.
