Cast-Based Guided Implant Placement and Prosthetic Rehabilitation of a Single Edentulous Space: Case Report and Systematic Analysis of Surgical Guides Used in Implant Dentistry.

This report discusses a clinical case of prosthetic rehabilitation of a single edentulous space using cast-based guided implant placement, a surgical protocol for correct implant installation. It also provides a rundown of various techniques used and surgical guides available in dental implantology. Correct and preplanned implant positioning and angulation are the adjuncts to a successful implant-supported restoration.

Development of a Fast SARS-CoV-2 IgG ELISA, Based on Receptor-Binding Domain, and Its Comparative Evaluation Using Temporally Segregated Samples From RT-PCR Positive Individuals.

SARS-CoV-2 antibody detection assays are crucial for gathering seroepidemiological information and monitoring the sustainability of antibody response against the virus. The SARS-CoV-2 Spike protein's receptor-binding domain (RBD) is a very specific target for anti-SARS-CoV-2 antibodies detection. Moreover, many neutralizing antibodies are mapped to this domain, linking antibody response to RBD with neutralizing potential.

Ultrasensitive and Robust Point-of-Care Immunoassay for the Detection of Malaria.

malaria is widespread in the tropical and subtropical regions of the world. There is ongoing effort to eliminate malaria from endemic regions, and sensitive point-of-care (POC) diagnostic tests are required to support this effort. However, current POC tests are not sufficiently sensitive to detect in asymptomatic individuals.

Prosthodontic rehabilitation of patient with flabby ridges with different impression techniques.

A fibrous or flabby ridge is a superficial area of mobile soft tissue affecting the maxillary or mandibular alveolar ridges. It can develop when hyperplastic soft tissue replaces the alveolar bone and is a common finding particularly in the upper anterior region of long term denture wearers. Masticatory forces can displace this mobile denture-bearing tissue, leading to altered denture positioning and loss of peripheral seal.

Effect of firing cycle and surface finishing on the sag resistance of long-span metal ceramic framework using base metal alloys-an in vitro study.

Background: The search for the ideal restorative material or combination of materials in dentistry is still the subject of modern dental research. In clinical practice, there are increased numbers of ceramo-metal restorations being fabricated which replace multiple missing teeth in a single framework. The literature is scanty with regard to investigations of the 'sag' resistance of base metal alloys commonly used for ceramo-metal restorations and specifically for long-span restorations.

An evaluation of fracture resistance of interim fixed partial denture fabricated using polymethylmethacrylate and reinforced by different fibres for its optimal placement: an in vitro study.

Background: Polymethylmethacrylate (PMMA) is the most common material used to fabricate interim fixed partial denture (FPD). Several attempts have been made to improve fracture strength of this material with various methods of reinforcement, but its effect on the fracture resistance of interim FPD was not evaluated.

Method: The study was designed in two stages.

Effect of water temperature and duration of immersion on the marginal accuracy of provisional crowns.

Background: Fabrication of fixed restorations is time consuming. It is vital that the prepared teeth be protected by means of an interim restoration till the time definitive prostheses can be delivered. Marginal adaptation is one of the most important requirements for an interim restoration.

Dimensional Accuracy of Castings Fabricated with Ring-less and Metal Ring Investment Systems for Implant Supported Fixed Dental Prosthesis: An In-vitro Comparative Study.

Background: The ring-less investment system is in use for dental casting, although there was no adequate scientific data to support its use either for conventional fixed dental prosthesis or implant retained fixed dental prosthesis.

Methods: An in-vitro study was undertaken to compare the vertical marginal accuracy of single full coverage metal restorations, between ring-less and metal ring investment techniques, using two different investment materials, for implant supported fixed dental prosthesis. Three groups were made of ten samples each.
