Considerations preliminary to the application of early and immediate loading protocols in dental implantology.

In oral implantology, a 3-6 month stress-free healing period is presently accepted as a prerequisite to achieve bone apposition without interposition of a fibrous scar tissue. This protocol was introduced by Brånemark and co-workers in 1977. The aim of the present paper is to review the reasons that led Brånemark and collaborators to require long delayed loading periods.

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.

[Parietal grafts in maxillofacial and pre-implant surgery].

Due to the recent regulations generated by the diversity of infectious risks, autologous bone is the standard graft material in maxillofacial surgery. Although synthetic biomaterials can be useful, they remain insufficient in many situations. Among the many sites offering graft material, monocortical parietal bone which is accessible within the craniocephalic operative field has distinguishing characteristics due to its membranous embryological origin and its mode of direct ossification which does not include a cartilaginous stage.

Timing of loading and effect of micromotion on bone-dental implant interface: review of experimental literature.

A significant no-load healing period is the generally accepted prerequisite for osseointegration in dental implantology. The aim of this article was to examine whether this no-load healing period is validated by the experimental literature. In vivo histological data was scrutinized to identify the effect of early loading protocols on the bone-implant interface.

[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.
