At the Consensus Conference, one of the tasks of the researchers is periodically to reassess the criteria adopted for scientific experimentations. For this purpose the authors analysed a selection of publications concerning in vivo experiments and checked the quality of the protocols adopted and the experimental models used. Among the publications included in the review, one of the works by the ARDEC group on Premium implants (Caneva et al., 2010) obtained a very high score in the judgement of the quality of execution.

This publication gives the final data of the work anticipated at EAO Annual Scientific Meeting 2012. The clinical indication that may be drawn from the research is that a thickness of residual vestibular bone greater than 1 mm at the moment of implant insertion helps preserve the level of the bone crest and maintain a better aesthetic result over time.

The research compared the levels of healing of bone tissues and the quantity of soft tissues at the level of the buccal wall of implants positioned in sites with 1 mm (test) and with 2 mm (control) of vestibular bone. At three months, the vestibular bone was vertically reabsorbed by about 1 mm in both cases, while the horizontal resizing was greater in the control sites than in the test sites. On the other hand the soft tissues, initially thin, regained a biological width that was able to compensate the bone loss.

The deeper and more lingual positioning of post extraction implants allows better maintenance of the vestibular bone crest.

In immediate implants, the use of re-absorbable membranes in collagen helps preserve the vestibular bone profile.

In immediate extractions, the two surgical fl ap and fl apless surgical approaches do not have a signifi cantly different infl uence on the reabsorption of the buccal alveolar crest.

The authors used magnesium-enriched hydroxyapatite (MHA) to fi ll the peri-implant defects in immediate sockets and observed that the bone recovery in the presence of this fi ller helped to better preserve the profi le of the bone crest in the absence of biomaterials. The difference was not significant.

This experimental study confirms the validity of the concept of distance osteogenesis, which has already been discussed in literature. Without the use of grafting materials, the bone can regenerate itself and occupy empty spaces, increasing in the direction of the implant surface and from the bottom upwards, in times proportional to the size of the defect.

The authors histologically verified in dogs the success of implants installed in the lower jaw in connection with the procedure of vertical and horizontal crest lift with autologous bone (control) and deproteinized bovine bone mineral (DBBM test). After 3 months, all the implants were stable. Those installed in autologous bone were completely integrated with the bone, while those in DBBM presented greater integration in the section in contact with parental bone.

This work studied the dimensional changes of tissues around the implants. After insertion of post-extraction implants in dogs with the use of deproteinized bovine bone mineral (DBBM test sites) to fill the coronal bone defects around the implant without the use of grafting material (control sites), impressions were taken at baseline and at 4 months. The impressions were casted and the models at the two different periods were compared with the use of three-dimensional measuring software. The histomorphometric aspects at 4 months were also compared. The test sites filled with DBBM had a much greater capacity to maintain the vertical buccal dimension compared to the control sites.
