The role of angiogenesis in implant dentistry part II: the effect of bone-grafting and barrier membrane materials on angiogenesis

2016

Background : In implant dentistry, bone substitute materials and barrier membranes are used in different treatments including guided bone regeneration (GBR), socket preservation, alveolar ridge augmentation, maxillary sinus elevation, and filling bony defects around the inserted dental implant. One of the most important factors in prognosis of treatments using these materials is the growth of new blood vessels in applied areas. Present review was performed to evaluate the effect of the bone-grafting and barrier membrane materials on angiogenesis events. Material and Methods : An electronic search was performed in PubMed, MEDLINE, and EMBASE databases via OVID using the keywords mentioned in…

Intraoral onlay block bone grafts versus cortical tenting technique on alveolar ridge augmentations: a systematic review

2021

To review systematically the bone gain and superficial resorption rate of the onlay block bone grafts versus the cortical tenting technique, as well as secondarily study the postoperative complications, implant survival and success rates, and peri-implant marginal bone loss. Following the recommended methods for systematic reviews and meta-analyses (PRISMA), an electronic search was performed in the PubMed (MEDLINE), EMBASE and the Cochrane Library of the Cochrane Collaboration (CENTRAL) databases to identify all relevant articles published up to March 2021 on onlay block bone grafts and cortical tenting technique. Eighteen papers complied with the inclusion criteria. In onlay grafts, the v…

Indirect Osteotome Maxillary Sinus Floor Elevation: An Update

2012

The objective was to review publications on indirect osteotome maxillary sinus floor elevation (OMSFE) procedures. Studies published between 1999 and 2010 on patients with a minimum of 1 year of follow-up were analyzed. Fourteen studies were included. Indirect OMSFE is indicated for a bone height of 6–8 mm. More bone height was gained when graft material was used. Schneiderian membrane perforation was the most frequent complication. Survival rates varied between 93.5% and 100%. Osteotome sinus membrane elevation is a predictable and effective procedure for placing implants in areas of the posterior maxilla with low bone height.

Effect on osseointegration of two implant macro-designs:A histomorphometric analysis of bicortically installed implants in different topographic site…

2018

Background To evaluate the effect of two different implant macro-designs on the sequential osseointegration at bicortically installed implants in the rabbit tibia. A further aim is to compare the osseointegration at different topographic zones. Material and Methods 27 New Zealand rabbits were implemented. Two implants, one for each macro-design (Ticare Inhex® or Ticare Quattro®, Mozo-Grau, Valladolid, Spain), were randomly implanted in the diaphysis or metaphysis of each tibia. The flaps were sutured to allow a submerged healing. The animals were sacrificed after 2, 4 or 8 weeks. Ground sections were prepared and analyzed. Results No statistically significant differences were found between …

Immediate loading implants: Review of the critical aspects

2018

Purpose. Modern dentistry have witnessed, a rapid and continuing evolution. Concerning the implant-rehabilitation protocols, they have beenEdizioniredefined in order to satisfy patient’s increasing expectations in terms of comfort, aesthetic and shorter treatment period. The purpose of this review is to explore the concept of implant immediate loading and the indications for clinical practice. All the critical aspects that could influence the outcomes of this treatment will also be considered. Materials and methods. Three protocols for implant load timing have been classified: immediate loading implants (ILI); early loading implants (ELI); and conventional loading implants (CLI). Two subc…

Effects of locally applied Insulin-like Growth Factor-I on osseointegration.

2019

Background The aim of this study was to assess the effect of local application of IGF-I on osseointegration of dental implants placed in osteoporotic bones. Material and Methods 16 rabbits were randomly distributed into two groups: eight animals were ovariectomized and fed a low-calcium diet for six weeks, in order to induce experimental osteoporosis, and the others were sham-operated and fed a standard diet. A titanium implant was inserted into the tibiae in both groups. In half of the rabbits, 4 μg of IGF-I was applied into the ostectomy, prior to the implant insertion. A total of 32 implants were placed. Animals were sacrificed two weeks after surgery and decalcified samples were process…

Osseoconductivity of a Specific Streptavidin-Biotin-Fibronectin Surface Coating of Biotinylated Titanium Implants - A Rabbit Animal Study

2015

Background Biofunctionalized implant surfaces may accelerate bony integration and increase long-term stability. Purpose The aim of the study was to evaluate the osseous reaction toward biomimetic titanium implants surfaces coated with quasicovalent immobilized fibronectin in an in vivo animal model. Materials and Methods A total of 84 implants (uncoated [control 1, n = 36], streptavidin–biotin coated [test 1, n = 24], streptavidin–biotin–fibronectin coated [test 2, n = 24]) were inserted 1 mm supracortically in the proximal tibia of 12 rabbits. The samples were examined after 3 and 6 weeks. Total bone-implant contact (tBIC; %), bone-implant contact in the cortical (cBIC; %) and in the spong…

Although Roman inscriptions have attracted interest since the Renaissance, epigraphy was not acknowledged as a science in its own right, with its own ruleset and methods, until the mid-19th century. Henceforth every newly discovered inscription was duly documented and distributed across an ever-growing and influential network of European scholars, giving birth to an extensive system of scholarly correspondence connecting every individual researcher with the community, from the provincial antiquarian who, as a precursor to « field archaeology », would discover the inscriptions, to the Parisian scholar who would gather and examine every inscription sent his way. One such epistolary intercours…
