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.

This experimental study in dogs showed how the vertical height of buccal bone reabsorption in immediate post-extraction sites is greater if the vestibular bone theca is thin.

IMMEDIATE IMPLANTS AT EXTRACTION SOCKETS: CRITICAL FACTORS ON TISSUE HEALING

This extensive revision of the literature, which involved 4 studies on Sweden & Martina implants out of a total of 12, evaluated the critical factors of post-extraction implants. In order to limit the inevitable reabsorption of the buccal wall, the clinical results of the studies indicate the use of implants with a smaller diameter, which must be positioned more towards the lingual/palate side.

The authors histologically tested in dogs the effective behaviour of distance osteogenesis, artificially creating peri-implant gaps of different sizes around implants inserted 3 months after dental extraction. At one month from insertion, it was noted that the peri-implant defects were being filled with newly formed bone that grew from the bottom and from the walls of the defect towards the implant surface. The gap was more or less filled in relation to its initial size, no gap was completely reconstructed.

The authors verified bone behaviour at 3 months around experimental implants inserted in sites with a peri-implant gap of 1.2 mm, left to heal without biomaterials, only with coagulum (control) and filled with DBBM (test). They found that at 3 months the gap was largely occupied by connective tissue, the residual defect was significantly less in sites with coagulum (0.48 mm) compared to sites with DBBM (0.88 mm).

In the vestibular portion of immediate post-extraction implants, a graft of connective tissue obtained from the palate was positioned in vivo to test their capacity to preserve hard tissues (Test Group). At 4 months, bone reabsorption did not show any significant differences, with respect to the Control Group in which the graft had not been positioned, but there was a greater amount of mucous tissue in the Test Group. Clinically it is therefore useful to use a connective graft when there is a high aesthetic expectation.

The different positioning of immediate post-extraction implants was tested in vivo: in one group the implants were placed with the smooth portion of the neck at crestal level, in the other group 2 mm subcrestal. Within the limits of this study, the implants positioned at subcrestal level showed less bone reabsorption, as well as higher BIC values.

This study analyzed the different sequential healing phases of cortical bone vs bone marrow after 5, 10, 20 and 30 days. In cortical bone, the replacement of old bone with new bone was closely linked to remodelling of the individual BMUs, while in the bone marrow, new bone developed in very dense successive layers.
