Immediate loading with fixed full-arch prostheses in the maxilla: review of the literature
2014
Objectives: To critically review the evidence-based literature on immediate loading of implants with fixed full- arch prostheses in the maxilla to determine 1) currently recommended performance criteria and 2) the outcomes that can be expected with this procedure. Study Desing: Studies from 2001 to 2011 on immediate loading with fixed full-arch maxillary prostheses were reviewed. Clinical series with at least 5 patients and 12 months of follow-up were included. Case reports, studies with missing data and repeatedly published studies were excluded. In each study the following was assessed: type of study, implant type, number of patients, number of implants, number of implants per patient, us…
Volumetric variation of peri-implant soft tissues in convergent collar implants and crowns using the biologically oriented preparation technique (BOP…
2018
Background To evaluate the changes in the peri-implant soft tissues of convergent collar implants with biologically oriented preparation technique (BOPT) crowns, 10 months after loading. Material and Methods A pilot study was carried out from January 2016 to October 2017 involving 14 patients with one or two implants in the posterior mandibular sector. A total of 32 convergent collar implants were placed using a non-submerged protocol. Three months later the provisional cemented crowns were fitted using the BOPT approach with the finish line 1-1.5 mm below the gingival margin, simulating coronal emergence of a natural tooth. The soft tissue changes were measured with an intraoral scanner at…
Part I: Relationship among Training Load Management, Salivary Immunoglobulin A, and Upper Respiratory Tract Infection in Team Sport: A Systematic Rev…
2021
Immunoglobulin A (IgA), which is the first line of defense against upper respiratory tract viruses, has been related with training load management. This article aimed to systematically identify and summarize (1) the studies that have found a relationship between training load and salivary IgA in team sports, and (2) the studies that have highlighted a relationship between IgA and upper respiratory tract infection (URTI) in team sports. A systematic review of relevant articles was carried out using two electronic databases (PubMed and WoK) until 3 October 2020. From a total of 174 studies initially found, 24 were included in the qualitative synthesis. This systematic review confirmed that lo…
Transmission of human immunodeficiency virus Type-1 by fresh-frozen plasma treated with methylene blue and light
2015
BACKGROUND The risk of transfusion-transmitted infection (TTI) has been minimized by introduction of nucleic acid testing (NAT) and pathogen inactivation (PI). This case report describes transmission of human immunodeficiency virus Type 1 (HIV-1) to two recipients despite these measures. STUDY DESIGN AND METHODS In March 2009 a possible TTI of HIV-1 was identified in a patient that had received pooled buffy coat platelet concentrate (BC-PLT) in November 2005. The subsequent lookback study found two more patients who had received methylene blue (MB)-treated fresh-frozen plasma (FFP) and red blood cells (RBCs) from the same donation. In November 2005 the donor had tested negative for both HIV…
Immediate Loading with Fixed Full-Arch Prosthesis in the Edentulous Patient: Treatment Protocol
2019
Immediate loading is basically a prosthetic concept. However, the surgical implantological planning is very important to ensure a primary stability in the total edentulous patient. This characteristic is crucial to allow immediate loading in this type of patients. For the first time, the incisional design has allowed the clinician to overview about the surgical side. Later, maybe, the bone will need an osteoplasty to regularize possible bone defects. To ensure primary stability, it can use methods to enhance primary stability as undersized drilling technique and use of osteotomes and bi-cortical anchorage implants. There are two main protocols to obtain temporary immediate loading full-arch…
Introduction to Immediate Loading in Implantology
2019
Branemark traditional recommendation was to perform implant rehabilitation in two stages: the first entry was only for implant placement; after 3–6 months of undisturbed submerged healing for mandible and maxilla, respectively, a second surgical entry would have allowed loading of the implants. The rationale behind this approach was that implant micro-movements as consequence by an inadequate primary stability, caused by functional forces at the bone-implant interface in the early wound healing stages, could have induced fibrous tissue formation rather than new bone, eventually causing clinical failure. The main request was to reduce the overall rehabilitation time from surgery to final res…
Guided Surgery and Immediate Loading
2019
Computer-assisted implant dentistry can contribute for a better treatment planning, for the implementation of the implant placement, for capturing the intraoral situation, for processing data to design temporary and final prostheses, and for the manufacturing of prosthetic components.
Pedagogical experiments with MathCheck in university teaching
2019
MathCheck is a relatively new online tool that gives students feedback on their solutions to elementary university mathematics and theoretical computer science exercises. MathCheck was designed with constructivism learning theory in mind and it differs from other online tools as it checks the solutions step by step and shows a counter-example if the step is incorrect. It has been in student use since the autumn of 2015 and under design-based research from the first online day. The main research questions of this study are the following. 1) How can the usage of MathCheck support the aspects of conceptual understanding and procedural fluency of constructivism learning? 2) How can MathCheck em…
Addition reactions of heterocycles—IV
1973
Abstract The reactivity of indole derivatives towards nitrilimines has been studied. Substituents at positions 1, 2 and 3 of the indole ring greatly affect the course of the reaction. 1,3-Dipolar cycloaddition products (3a,8a,dihydropyrazole-[3,4-b]-indole derivatives) and non-cyclic addition products (3-indolyl derivatives) were obtained depending on these substituents. The structures reported were assigned on the basis of satisfactory analytical, spectroscopic and chemical data.
