Versatility of transmucosal implants with zirconium ring. Case report.

Utiling zirconium characteristics, a biomaterial with high affinity with bone and gum, we have positioned in the same patient 2 transmucosal implants in titanium with a coronal ring in zirconium in 2 different manners. The first fixture was positioned with the ring in zirconium at the same level of the gum in order to obtain a good periodontal healing and esthetic without metallic transparencies. The second postestractive implant was positioned with the zirconium ring at the level of the crestal bone in order to reduce the gap between the fixture and the alveolar bone and to avoid the use of a resorbable barrier relying on the osteointegrative properties of zirconium.
