“…Maló et al (2015) (28,37) reported distal implant placement at 30° degrees, though in some cases they reached an inclination of up to 45° degrees, depending on the situation and anatomical location - in coincidence with other authors (18-20,22,31). The insertion torque of the implants described in the studies varied between 25 and 50 Ncm.…”

“…Once incision and detachment were performed, and as a safety measure or as a way to orientate placement of the distal jaw implants, some authors made a window in the maxillary sinus, locating the mesial wall (5,20,25-27,37). The same procedure was used in the jaw until reaching the emergence of the mental nerve (21,26).…”

“…Regularization of the bone crest was performed if considered opportune by the operator in dentate patients undergoing tooth extraction in the same surgery (17,19,20,30,32-34). Regarding distal implant placement, we found similar inclinations among studies.…”

ObjectivesTo systematically review the literature on the “all-on-four” treatment concept regarding its indications, surgical procedures, prosthetic protocols and technical and biological complications after at least three years in function.Study DesignThe three major electronic databases were screened: MEDLINE (via PubMed), EMBASE, and the Cochrane Library of the Cochrane Collaboration (CENTRAL). In addition, electronic screening was made of the ‘grey literature’ using the System for Information on Grey Literature in Europe - Open Grey, covering the period from January 2005 up to and including April 2016.ResultsA total of 728 articles were obtained from the initial screening process. Of these articles, 24 fulfilled the inclusion criteria. Methodological quality assessment showed sample size calculation to be reported by only one study, and follow-up did not include a large number of participants - a fact that may introduce bias and lead to misleading interpretations of the study results.ConclusionsThe all-on-four treatment concept offers a predictable way to treat the atrophic jaw in patients that do not prefer regenerative procedures, which increase morbidity and the treatment fees. The results obtained indicate a survival rate for more than 24 months of 99.8%. However, current evidence is limited due the scarcity of information referred to methodological quality, a lack of adequate follow-up, and sample attrition. Biological complications (e.g., peri-implantitis) are reported in few patients after a mean follow-up of two years. Adequate definition of the success / survival criteria is thus necessary, due the high prevalence of peri-implant diseases. Key words:All-on-four, all-on-4, tilted implants, dental prostheses, immediate loading.

SUMMARY:The aim of this study was to examine the prevalence, location and morphology of maxillary sinus septa, and in particular sagittally orientated forms, which cannot be visualized by classic 2D x-rays. Thereby authors would like to provide information about the potential patient group, to be referred for the computed tomography scan before sinus lift procedure. The analysis was based on 216 computed tomography archival images. The exclusion criterion was occurrence of any suspected pathology in the maxillary region. The septa prevalence that was investigated in computed tomography was high (49%) with the mean height of 5.44 mm. The incidence of sagittally orientated septa as a challenge in 2D x-rays was 10%, with the second molar region as the most frequent location. Based on the obtained results and radiation safety principles, the authors suggest that orthopantomogram x-ray may be a sufficient ancillary radiological examination before beginning preimplant surgical procedure in the area of the maxillary sinus.

“…For two decades, the most significant aspects of implantology that were studied were related to osseointegration and the stability of marginal ridges. [1,2] These factors are still widely studied today, but biomechanics and function, [3] surface and anatomy of the implants, [4,5] esthetics, [6] and knowledge of risk factors, [7] are also studied. These features, in addition to increasing the quality of life for people [8] in need of dental implants, have delineated a new horizon in this promising area of research.…”

Background: The objective of this paper was to present a methodology for osseointegration in rat mandibles. Materials and Methods: A total of 16 Wistar male rats with 400 g were undergone to anesthesia, and then blunt instruments were used to expose the alveolar inferior nerve. Once the nerve canal was emptied, one implant (2.2 mm × 4 mm) was installed near the mandibular canal. The animals were sacrificed within the experimental period of 15 (n = 8) and 30 (n = 8) days. The histomorphometric analysis included both boneimplant contact and bone area. Results: In a comparison of the variables between 15 and 30 days, there were differences in bone maturation (Student's parametric test for independent samples -P < 0.05). In addition, the technique was shown to be reproducible and performed at a lower cost compared with histological studies involving other animals. Conclusion: This specific technique of placing implants into the mandibles of rats is a viable alternative in studies of this nature.
