Objectives
The purpose of this work is to provide a classification of bone density for mandibular and maxillary anatomical structural areas. A proper pre-implant diagnosis that takes this aspect into due account represents a prognostic factor of primary importance specifically with reference to immediate load procedures.
Materials and methods
The device used for this research allows a site-specific intraoperative evaluation of bone density. A total of 1254 implants were analyzed and the data pertaining to the detected bone type were reviewed in depth. Based on this research, a classification of the anatomical structural areas on a clinical statistical basis was suggested.
Results and conclusions
Knowing the qualitative and quantitative availability of an anatomical structural area in advance allows us to face even complex implant-prosthesis rehabilitation with a diagnostic datum that has been difficult to extrapolate so far from investigation techniques but with a high prognostic value. The new classification suggested by the authors allows for a quicker and more intuitive selection of applicable devices.

Objectives
The aim of this paper is to assess the risk factors that could influence the esthetic and long term results of implant placement in fresh extraction sockets.
Materials and methods
The immediate implant risk factors that could influence the final outcome are analyzed and could be summarized in: the peri-implant soft tissue biotype, the vestibular bone thickness, the alveolar host infected site, the residual peri-implant gap and the final implant position. Furthermore a diagnostic parameter that could influence the therapeutic approach is proposed.
Discussion
Several factors have been proposed as being important in determining the stability of the peri-implant mucosa, including implant shoulder position in the bucco-lingual and apico-coronal direction and tissue biotype. The initial thickness of the buccal crestal bone may be a factor in determining the extent of the vestibular bone resorption. Thick soft and hard peri-implant tissues could contribute to marginal stability. Infected alveolar site is not a contradiction to implant placement and the peri-implant gap should be grafted in order to minimize the horizontal resorption. The implant position and diameter should be carefully analyzed in order to preserve peri-implant soft tissue stability.
Conclusions
Marginal tissue recession, occurred at both thin and thick biotype sites. When implants are placed immediately after tooth extraction, the implant-vestibular plate distance is a critical parameter to evaluate, and can be a useful diagnostic parameter that guides the clinician in the choice of the most appropriate grafting procedure. Grafting the marginal defects may limit the horizontal resorption, however “overbuilding” the buccal aspect may be a suitable technique to compensate for the physiological alveolar bone changes.

Objectives
The aim of this systematic review was to investigate the correlation between periodontal disease and adverse pregnancy outcomes and to evaluate the effect of periodontal therapy during pregnancy in reducing the incidence of preterm birth and low birth weight.
Materials and methods
We searched electronic databases (MEDLINE, EMBASE, Cochrane Central Trials Registry) for case-control studies, prospective studies, and clinical trials and carried out a meta-analysis of data from selected randomized clinical trials.
Results
A total of 37 studies were included in the present analysis. Two hundred and one preterm births (10.2%) were reported in the experimental groups compared with 186 (9.4%) in control groups, for an odds ratio (OR) of 1.01 (95% CI: 0.74-1.38; p = 0.93). As for low birth weights, 164 (8.2%) of these events were reported in experimental groups and 153 (7.6%) in control groups for an OR of 1.08 (95% CI: 0.86-1.36; p = 0.53).
Conclusion
We found no clear evidence that periodontal disease is a major risk factor for adverse pregnancy outcomes, although it may exert a minor effect. Non-surgical periodontal therapy is safe during pregnancy, but we found no evidence of its efficacy in reducing the incidence of preterm birth or low birth weight.

Objectives
Aim of the paper was to make a revision on the bone microstructure adaptive mechanisms and function around dental implants and biomaterials.
Materials and methods
The bone architecture was compared on the basis of ten years of histological evaluations made in both human and animal models. The following were treated in detail: immediate loading effect on bone collagen fiber orientation; osseointegration of dental implants in presence of biomaterials simultaneously placed with implants; bone microstructure differences between humans and animal models usually used in dental research.
Results
Immediate loading procedure improves the peri-implant bone matrix organization. Likewise, the prevalent transverse collagen fibers orientation increases bone strength to compressive loads. Moreover, under an adequate mechanical stimulus the peri-implant bone became compact. A prevalent de novo bone formation around biomaterial's particles and a peri-implant “focal” osseintegration could be seen in the case of simultaneous placement of biomaterial and implants. Compared to humans, the bone microstructure and physiology of the most used animal models for in vivo studies appear to be significantly different.
Conclusions
In implants with an adequate primary stability, immediate loading procedure improves the quality of osseointegration. Progressive loading procedure should be used after the second stage surgery in implants simultaneously inserted with a biomaterial. In in vivo animal research, both objectives of the studies and ethical considerations should be considered to choose the animal model.
