Each side of the mandible was allocated to one of two healing periods (8 or 16 weeks). The histomorphometric analysis assessed the percentage of bone, soft tissue, and DBBM in the regenerate; the absolute area in square millimeters of the bone regenerate; and the distance in millimeters from the bottom of the defect to the highest point of the regenerate.<\/jats:p><jats:p><jats:bold>Results:<\/jats:bold> In the 8\u2010week healing group, two dehiscences occurred with CCM. After 8 weeks, all treatment modalities showed no significant differences in the percentage of bone regenerate. After 16 weeks, the percentage of bone had increased for all treatment modalities without significant differences. For all groups, the defect fill height increased between weeks 8 and 16. The CCM group showed a statistically significant (<jats:italic>P<\/jats:italic> = 0.0202) increase over time and the highest value of all treatment modalities after 16 weeks of healing.<\/jats:p><jats:p><jats:bold>Conclusions:<\/jats:bold> The CCM showed a limited beneficial effect on bone regeneration in membrane\u2010protected defects in dog mandibles when healing was uneventful. The observed premature membrane exposures resulted in severely compromised amounts of bone regenerate. This increased complication rate with CCM requires a more detailed preclinical and clinical examination before any clinical recommendations can be made.<\/jats:p>","DOI":"10.1902\/jop.2007.070102","type":"journal-article","created":{"date-parts":[[2007,10,4]],"date-time":"2007-10-04T08:25:09Z","timestamp":1191486309000},"page":"1943-1953","source":"Crossref","is-referenced-by-count":68,"title":["Effect of Two Different Bioabsorbable Collagen Membranes on Guided Bone Regeneration: A Comparative Histomorphometric Study in the Dog Mandible"],"prefix":"10.1002","volume":"78","author":[{"given":"Michael M.","family":"Bornstein","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dieter","family":"Bosshardt","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daniel","family":"Buser","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2007,10]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.1902\/jop.2001.72.2.215"},{"key":"e_1_2_8_3_1","doi-asserted-by":"publisher","DOI":"10.1046\/j.0906-6713.2003.03304.x"},{"key":"e_1_2_8_4_1","first-page":"29","article-title":"Localized ridge augmentation using guided bone regeneration.
