Additionally, we compared anodized WE43 implants with monolithic ones and clarified the effect of the anodization. WE43 cylindrical implants with and without anodization (length, 10 mm; diameter, 0.3 mm) were transplanted into the rat tibia. In both groups, the development of corrosion and the change in implant volume were evaluated by in vivo micro-computed tomography until 12 months, and the bone tissue reaction was observed histologically. In the monolithic WE43 implants, hydrogen gas was evident until 14 days and the volume loss was 36.3% after 12 months. In the anodized WE43 implants, the development of hydrogen gas was inhibited and the volume loss was 27.7% after 12 months. The anodized WE43 implants showed a significantly slower corrosion process in the early phase. Therefore, these implants may require a prolonged period to degrade completely and may even resist complete degradation. At one year post surgery, bone maturation progressed and lamellar bone structure developed around the implant in both groups. In conclusion, the WE43 implants showed good long-term stability and biocompatibility in bone tissue.<\/jats:p>","DOI":"10.1177\/0885328218822050","type":"journal-article","created":{"date-parts":[[2019,2,12]],"date-time":"2019-02-12T21:32:40Z","timestamp":1550007160000},"page":"1157-1167","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":32,"title":["Degradation and interaction with bone of magnesium alloy WE43 implants: A long-term follow-up in vivo rat tibia study"],"prefix":"10.1177","volume":"33","author":[{"given":"Narumi","family":"Oshibe","sequence":"first","affiliation":[{"name":"Maxillofacial surgery, Graduate School of Medical and Dental Sciences, Tokyo Medical and Dental University, Tokyo, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7319-8159","authenticated-orcid":false,"given":"Eriko","family":"Marukawa","sequence":"additional","affiliation":[{"name":"Oral and Maxillofacial Surgery, Graduate School of Medical and Dental Sciences, Tokyo Medical and Dental University, Tokyo, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tetsuya","family":"Yoda","sequence":"additional","affiliation":[{"name":"Maxillofacial surgery, Graduate School of Medical and Dental Sciences, Tokyo Medical and Dental University, Tokyo, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hiroyuki","family":"Harada","sequence":"additional","affiliation":[{"name":"Oral and Maxillofacial Surgery, Graduate School of Medical and Dental Sciences, Tokyo Medical and Dental University, Tokyo, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2019,2,7]]},"reference":[{"key":"bibr1-0885328218822050","doi-asserted-by":"publisher","DOI":"10.1016\/j.actbio.2010.02.028"},{"key":"bibr2-0885328218822050","doi-asserted-by":"publisher","DOI":"10.1159\/000339380"},{"key":"bibr3-0885328218822050","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(07)60853-8"},{"key":"bibr4-0885328218822050","doi-asserted-by":"publisher","DOI":"10.1583\/04-1349R.1"},{"key":"bibr5-0885328218822050","doi-asserted-by":"publisher","DOI":"10.1007\/s10439-014-1169-3"},{"key":"bibr6-0885328218822050","doi-asserted-by":"publisher","DOI":"10.2174\/1871529X14666140823121609"},{"key":"bibr7-0885328218822050","doi-asserted-by":"publisher","DOI":"10.1016\/j.carrev.2014.01.011"},{"key":"bibr8-0885328218822050","doi-asserted-by":"publisher","DOI":"10.1007\/s10853-012-6572-2"},{"key":"bibr9-0885328218822050","doi-asserted-by":"publisher","DOI":"10.1097\/00006534-199410000-00004"},{"key":"bibr10-0885328218822050","doi-asserted-by":"publisher","DOI":"10.1302\/0301-620X.80B2.8302"},{"key":"bibr11-0885328218822050","doi-asserted-by":"publisher","DOI":"10.1016\/0142-9612(95)91092-D"},{"key":"bibr12-0885328218822050","doi-asserted-by":"crossref","unstructured":"Marukawa E, Tamai M, Takahashi Y, et al.
