[Ceramic implants to benefit complete lower dentures].

In our Department of implantology, 141 ceramic implants were put in place with the objective of stabilizing a complete mandibular prosthesis in 39 patients. Despite the small number of cases reported, statistical analysis was informative because of the homogeneity of the conditions: the same indication for a prosthesis; the same operator for the surgery as well as the prosthesis; The very good follow-up with all but 2 patients having been monitored regularly. In addition to the finding that our results are practically superposable on those obtained with titanium implants over the same period of time. We share our experience with ceramic materials; dispel their reputation of fragility, especially since the advent of zirconium; and emphasize the simplicity of these "artificial roots" that can be use without prefabricated and costly intermediate parts.

Evaluation of combinations of titanium, zirconia, and alumina implants with 2 bone fillers in the dog.

The quality of the tissue-implant interface was evaluated using light and scanning electron microscopy with morphometric analysis. Nine dogs were implanted with 3 types of dental implants (titanium, zirconia, or alumina). A total of 24 dental implants was placed in mandibular bone previously filled with coral carbonate calcium (corail) or hydroxyapatite. The study results in breaking the concept of osseointegration into 2 phases: "osseocoaptation," which concerns only the interface (physical contact between the implants and the bone without interpenetration process), and "osseocoalescence," which relies on an interpenetration of the bioactive material, which almost entirely disappears, being substituted by newly formed bone. There was no significant statistical difference between the 3 types of implants. Both fillings showed good ossecoalescence properties. However, hydroxyapatite led to fibrous encystment, preventing osseocoaptation of implants. In contrast with calcium carbonate filling.
