Conclusions : Vitamin D deficiency in early implan...

To overcome the shortcomings of this case reports, prospective, multicenter, and controlled studies must follow to affirm a potential relationship between vitamin D deficiency, osteoimmunology, and the early failure of dental implants. Currently, a general recommendation for a standardized vitamin D screening in dental implantology cannot be stated due to lack of evidence.

Case presentation : Vitamin D deficiency in early ...

Nevertheless, the vitamin D deficiency prevalence in the European population indicates that a vitamin D deficiency is probably not a sole causative factor for early implant failure; otherwise, the early implant failure rate would be significantly higher. However, a synergistic effect with other factors is conceivable. Some authors stated that implant osseointegration is not simply a wound healing ...

Local and systemic factors can affect the survival rate of dental implants [30–33]. The causes of early implant failure are not fully clarified and an association between vitamin D and dental implant osseointegration has not been investigated properly [8, 13–16]. Some recent animal studies in rodents demonstrated a relationship between vitamin D supplementation and an increased bone to implant...

Within the limits of this systematic review, the chairside method to harvest BMAC is a viable option for maxillary sinus augmentation for implant site development. The implant survival of the BMAC group was similar to the laboratory FICOLL concentration of BMAC group, without the additional cost and time of laboratory cell isolation techniques. Single or double centrifugation of BMAC does not appe...

In addition, the parameters to evaluate new bone formation were variable. New bone formation and percentage of vital bone are different methods to measure bone formation, and the data from different methods could not be combined or analyzed together. Furthermore, the BMAC evaluated in test groups were prepared differently and were harvested from different sources (tibia or iliac). The control grou...

Although the variations of the materials and methods for BMAC preparation were discussed, this review was not aimed to compare materials and methods for BMAC preparation, but rather the end clinical result for new bone formation and implant survival. Although implant survival and new bone formation were not the only parameters to consider when evaluating sinus augmentation, these parameters were t...

It appears that BMAC offers no statistically significant advantage for regeneration of bone in the maxillary sinus for site preparation of dental implants. BMAC + bovine bone graft results in similar regeneration outcome measures histologically as alveolar bone alone at 3–4 months.

This reported observation indicating statistically more new bone regeneration in the BMAC + bovine bone graft group compared with ...

Sauerbier et al. [14] further compared BMAC + bovine bone grafts (test group) with alveolar bone, autologous + bovine bone grafts (control group) for maxillary sinus site preparation.

Mesenchymal stem cells (MSCs) in BMAC have the potential to renew, experience clonal expansion, and differentiate into musculoskeletal tissues [16]. MSCs are also known to have an immunoregulatory role and may enhance the normal healing response and angiogenesis [10]. BMAC has been used in bone, cartilage, and tendon injuries with encouraging results [16]. BMAC is a minimally invasive procedure, a...

Review : Maxillary sinus augmentation using chairs...

Maxillary sinus augmentation is indicated when there is an inadequate vertical alveolar bone height to effectively support surgically placed dental implants. The sinus elevation procedure requires grafting bone material onto the sinus floor to regenerate sufficient vertical alveolar bone height [1, 2]. The ideal bone grafting material should be biocompatible, possess no risk of disease transmissio...

Conclusions : Influence of exposing dental implant...

The current review showed that the exposure of dental implants in the sinus cavity without the augmentation procedure or graft materials shows a high survival rate of 95.6%, without statistically significant differences according to the level of penetration (lower or higher to 4 mm). Changes in maxillary sinuses in relation to protruding implants within the sinus cavity do not statically affect ...

Consequently, it seems that maxillary sinus changes in relation to protruded implants inside the sinus cavity and does not statically affect to implant survival rate neither to clinical nor radiographic complications. Several limitations could be described for the present review. Firstly, there is a lack of a control group in the included studies, to compare outcomes and complications, with impla...

Pneumatization of the maxillary sinus and resorption of the residual alveolar ridge following tooth extraction can compromise the dental implant placement. Similarly, extension of the dental implants inside the maxillary sinus cavity is not rare.

Materials and methods This systematic review and subsequent meta-analysis follow the guidelines of the PRISMA statement. Focus question The following focus question was developed: Is the intrusion of dental implants into the sinus cavity during implant drilling or implant placement, without regenerative procedure (lateral sinus lift or transalveolar technique) and graft material, has an effec...

Introduction ; Influence of exposing dental implan...

Introduction The edentulous posterior maxillary region often presents with unique challenging conditions in implant dentistry. Limited bone height secondary to pneumatization of the maxillary sinus and the resorption of the alveolar ridge preclude in many instances the installation of dental implants. To compensate for the lack of bone height, several treatment options have been proposed. The ...

Influence of exposing dental implants into the sinus cavity on survival and complications rate: a systematic review   Abstract Background After tooth loss, the posterior maxilla is usually characterized by limited bone height secondary to pneumatization of the maxillary sinus and/or collapse of the alveolar ridge that preclude in many instances the installation of dental implants. In order ...
