The influence of acetylsalicylic acid on bone regeneration: systematic review and meta-analysis.

Acetylsalicylic acid (ASA) is commonly used as a non-steroidal anti-inflammatory drug that interferes with multiple biological pathways. ASA acts by stimulating osteogenesis and inhibiting osteoclastogenesis. Thus, the objective of this study was to perform a systematic review and meta-analysis to evaluate the effectiveness of the use of ASA in the bone regeneration in animal models.

Evaluation of the accuracy and stress distribution of 3-unit implant supported prostheses obtained by different manufacturing methods.

The purpose of this in vitro study was to measure the vertical, positive-horizontal, and negative-horizontal misfit (VM, PHM, and NHM, respectively) of the zirconia three-element prosthetic framework, fabricated using different methods, and compare them with conventional fabrication methods (lost-wax casting). Furthermore, this study aimed to evaluate the influence of the misfit values on the biomechanical behavior of the 3-unit fixed prosthetic frameworks using three-dimensional finite element analysis (3D-FEA). Forty frameworks (n = 10) were fabricated as follow: G1, Cerec Bluecam; G2, iTero; G3, 3Series; and G4, conventional method.

Sixteen 3D models of various configurations were simulated using InVesalius, Rhinoceros 3D 4.0, and SolidWorks 2011 software, and processed using Femap 11.

Analysis of vertical marginal discrepancy in feldspathic porcelain crowns manufactured with different CAD/CAM systems: Closed and open.

Objective: The objective of this study is to compare the marginal adaptation of feldspathic porcelain crowns using two computer-aided design/computer-aided manufacturing systems, one of them is open and the other is closed.

Materials And Methods: Twenty identical titanium abutments were divided into two groups: open system (OS), where ceramic crowns were created using varied equipment and software, and closed system (CS), where ceramic crowns were created using the CEREC system. Through optical microscopy analysis, we assess the marginal adaptation of the prosthetic interfaces.

Survival of dental implants placed in HIV-positive patients: a systematic review.

No consensus has been reached on the use of dental implants in human immunodeficiency virus (HIV)-positive patients. This systematic review evaluated dental implants in HIV-positive patients in terms of implant survival and success rates, marginal bone loss, and complications. The review was conducted according to the PRISMA checklist.

Self-ligating versus conventional metallic brackets on retention: A systematic review.

Objective: The present study aimed to review the literature systematically and assess comparatively whether self-ligating metallic brackets accumulate less biofilm than conventional metallic brackets.

Material And Methods: The systematic search was performed following PRISMA guidelines and registration in PROSPERO. Seven electronic databases (Google Scholar, LILACS, Open Grey, PubMed, SciELO, ScienceDirect, and Scopus) were consulted until April 2016, with no restriction of language and time of publication.

Comparison of external and internal implant-abutment connections for implant supported prostheses. A systematic review and meta-analysis.

Objective: The systematic review and meta-analysis aimed to answer the PICO question: "Do patients that received external connection implants show similar marginal bone loss, implant survival and complication rates as internal connection implants?".

Data: Meta-analyses of marginal bone loss, survival rates of implants and complications rates were performed for the included studies. Study eligibility criteria included (1) randomized controlled trials (RCTs) and/or prospective, (2) studies with at least 10 patients, (3) direct comparison between connection types and (4) publications in English language.

Management of Zygomatic Fixture Complication Case Using Extra-Short Implants.

The oral rehabilitation of a patient with atrophic maxilla is one of the main challenges in implant-supported rehabilitations. The implant placement in the posterior region of the maxilla is limited by a deficiency of bone quantity and quality, besides the anatomic restriction of the maxillary sinus. The use of zygoma fixtures, anchoraged in the zygomatic bone, is a useful technique to enable the full arch rehabilitation.

Finite element analysis of implant-supported prosthesis with pontic and cantilever in the posterior maxilla.

The aim of this study was to evaluate the influence of pontic and cantilever designs (mesial and distal) on 3-unit implant-retained prosthesis at maxillary posterior region verifying stress and strain distributions on bone tissue (cortical and trabecular bones) and stress distribution in abutments, implants and fixation screws, under axial and oblique loadings, by 3D finite element analysis. Each model was composed of a bone block presenting right first premolar to the first molar, with three or two external hexagon implants (4.0 × 10 mm), supporting a 3-unit splinted dental fixed dental prosthesis with the variations: M1 - three implants supporting splinted crowns; M2 - two implants supporting prosthesis with central pontic; M3 - two implants supporting prosthesis with mesial cantilever; M4 - two implants supporting prosthesis with distal cantilever.

Oral Health of Patients Hospitalized in the Intensive Care Unit.

Aim: Oral hygiene technique is an important factor in maintaining the health and comfort of hospitalized patients given the frequent presence of oral biofilm and pathogens brought on by mouth breathing. This is an important practice to assist patients in intensive care, in particular those who are intu-bated and under mechanical ventilation because the realization of oral hygiene reduces the patient's risk of complications and length of hospitalization. The objective of this research was to evaluate the oral health condition of patients hospitalized in an intensive care unit (ICU) and to clarify the importance of protocol standardization involving these patients' buccal hygiene.

Fibrovascularization and osteogenesis in high-density porous polyethylene implants.

High-density porous polyethylene (HDPP) has been extensively used in craniofacial reconstructions with high-level success and minimal complications. It is known for its biocompatibility and satisfactory stability in the receptor bone area, presenting only a few reports of mobility and infection. In the current study, attention was given to the interface area between HDPP and bone surface to analyze fibrous and bone tissue formation and ingrowth into the pores of the material placed in the mandible of rabbits.
