Immediate loading of variable-thread expanding tapered-body implants placed into maxillary post-extraction or healed sites using a guided surgery approach: An up-to-five-year retrospective analysis

Transitioning from failing dentition to complete-arch implant rehabilitation may involve temporarily rendering the patient edentulous. In order to avoid the use of a removable prosthesis, immediate implant placement and immediate loading with a fixed provisional prosthesis have been proposed.

Human pulps capped with PDGF: A pilot study

Growth factors have shown the potential to promote odontoblast-like cell di erentiation and induce the formation of reparative dentin. The aims of this pilot study were to develop a regenerative approach to pulp capping using platelet-derived growth factor (PDGF) BB and to describe histologically the pulp tissue response.

Impact of argon plasma treatment on microbiological surface receptivity of titanium implants: An in vitro study

Pretreatment of dental implants by argon plasma has been suggested to increase their surface energy and enhance integration of both hard and soft periimplant tissue. However, no data are available on the risk of implant sterility loss after this process. This study aimed to test whether the treatment of implant fixtures by argon plasma in conditions compatible with clinical use produced an increased risk of microbiological contami- nation.

Accelerated generation of human induced pluripotent stem cells from human oral mucosa using episomal plasmid vectors and maternal transcription factor Glis1

Induced pluripotent stem cells (iPSCs) possess high pluripotency and differentiation potential and may constitute a possible source of autologous stem cells for clinical applications. However, the lengthy reprogramming process (up to one month) remains one of the most significant challenges facing standard virus-mediated methodology. The Gli-like transcription factor Glis1 is highly expressed in unfertilized eggs and one-cell-stage embryos. In this study, iPSCs were generated using a combination of primary human oral mucosal fibroblasts (HOFs) and episomal plasmid vectors expressing transcription factors, including Glis1.

Three-year clinical and radiographic outcomes of patients treated according to the All-on-4 concept in the daily practice: A prospective observational study on implants and prosthesis survival rates and complications

All-on-4 treatment concept is widely applied for complete-arch rehabilitations. Nevertheless, minor technical and biological complications can occur. The objective of this study was to evaluate the three-year clinical and radiographic data of complete-arch fixed dental prostheses supported by four implants according to the All-on-4 protocol.
