Strain Assessment Around Two Short Implants Retaining Mandibular Overdenture with Different Attachment Systems: In- Vitro Study.

Purpose: The purpose of this study was to examine and compare the strain distribution around long and short implant mandibular overdentures retained either by ball or self-aligning stud (Positioner) attachments.

Material And Methods: Two completely edentulous mandibular models made of epoxy resin were used with implants placed equidistantly in the canine region. In the first model, two long implants were inserted, while two short implants were inserted in the second model.

Enhanced transformation efficiency in Treponema denticola enabled by SyngenicDNA-based plasmids lacking restriction-modification target motifs.

Oral spirochetes are among a small group of keystone pathogens contributing to dysregulation of tissue homeostatic processes that leads to breakdown of the tissue and bone supporting the teeth in periodontal disease. Additionally, our group has recently demonstrated that Treponema are among the dominant microbial genera detected intracellularly in tumor specimens from patients with oral squamous cell carcinoma. While over 60 species and phylotypes of oral Treponema have been detected, T.

Rehabilitation of Atrophic Mandible with Ultrashort Implants Combined with Photobiomodulation Therapy: A Split-Mouth Design Study.

Background: Atrophic edentulous mandible is a challenging clinical condition. Studies assessing the use of ultrashort implants to support overdentures are scarce; the optimum photobiomodulation (PBM) dose for enhancing osseointegration is yet unknown.

Objective: This study aimed to evaluate and compare mandibular overdentures assisted by two versus four ultrashort implants with adjunctive PBM therapy using two doses.

Biofilm formation by Streptococcus mutans and its inhibition by green tea extracts.

Dental Caries is considered one of the most existing and worldwide common diseases related to the oral cavity affecting both children and adults. Streptococcus mutans is the main cariogenic microorganism involved in the dental caries progression. Natural products such as herbal plants were found to have less side effects and economic value than those of the chemically synthesized antibiofilm agents.

Outcomes of Mandibular Overdentures Supported by Four Short Implants Combined with Photobiomodulation Therapy.

Purpose: The aim of this study was to clinically and radiographically evaluate mandibular overdentures supported by four short implants combined with two different doses of photobiomodulation (PBM).

Materials And Methods: A split-mouth design was applied; six completely edentulous male subjects received four short implants in the canine and second premolar area. Short implants were inserted via a digital fully guided approach with a stereolithographic surgical guide.

Clinical Efficacy of Photobiomodulation on Dental Implant Osseointegration: A Systematic Review.

Background: Photobiomodulation (PBM) has been shown to have a positive effect on dental implant osseointegration and stability in and animal studies; however, its usefulness in dental implant clinical practice is yet unclear.

Objective: The objective was to assess the clinical effectiveness of PBM on dental implants' osseointegration.

Methods: Two reviewers independently conducted a comprehensive electronic search of articles published from inception up to January 10, 2020, in PubMed, Cochrane Library and Embase databases following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines.

Effect of surface treated silicon dioxide nanoparticles on some mechanical properties of maxillofacial silicone elastomer.

Current materials used for maxillofacial prostheses are far from ideal and there is a need for novel improved materials which mimic as close as possible the natural behavior of facial soft tissues. This study aimed to evaluate the effect of adding different concentrations of surface treated silicon dioxide nanoparticles (SiO2) on clinically important mechanical properties of a maxillofacial silicone elastomer. 147 specimens of the silicone elastomer were prepared and divided into seven groups (n = 21).
