Evaluation of the inflammatory and osteogenic response induced by titanium particles released during implantoplasty of dental implants
(Scientific Reports, 2022)Implantoplasty is a mechanical decontamination technique that consists of removing the threads and polishing and smoothing the dental implant surface. During implantoplasty there is a large release of ... -
Factors affecting implant failure and marginal bone loss of implants placed by post-graduate students: a 1-year prospective cohort study
(Materials, 2020)Statement of the problem: Most of the clinical documentation of implant success and survival published in the literature have been issued by either experienced teams from university settings involving ... -
Fatigue of narrow dental implants: influence of the hardening method
(Materials, 2020)The use of narrow titanium dental implants (NDI) for small ridges, reduced interdental space, or missing lateral incisors can be a viable option when compared to the conventional wider dental implants. ... -
Finite element analysis relative to the crestal position of a 3.0-mm-diameter implant
(The International Journal of Periodontics & Restorative Dentistry, 2014)It has been shown that implant designs and different vertical positions have an influence on crestal bone. The purpose of this study was to use finite element (FE) analysis to biomechanically investigate ... -
Fracture and fatigue of titanium narrow dental implants: new trends in order to improve the mechanical response
(Materials, 2019-11-12)Sixty-four fractured commercially pure titanium (cp-Ti) narrow dental implants (NDIs) with similar macrogeometry and connection designs were studied after different implantation times in humans in order ... -
Immediate implant placement in molar extraction sockets: a systematic review and meta-analysis
(International Journal of Implant Dentistry, 2020)Background: Immediate implants are frequently employed in the anterior maxillary area. However, the installation of dental implants simultaneously with tooth extraction can also provide with benefits ... -
Immediate implants following tooth extraction. A systematic review
(Medicina Oral, Patologia Oral y Cirugia Bucal, 2012-03)Objectives: The aim of this article is to review the current state of immediate implants, with their pros and contras, and the clinical indications and contraindications. Material and Methods: An ... -
In vitro comparison of the accuracy of four intraoral scanners and three conventional impression methods for two neighboring implants
(PLoS ONE, 2020)Purpose: To determine whether the accuracy of two-implant model impressions taken with optical scanners was inferior to that of those taken with elastomeric materials. Materials and Methods: Impressions ... -
In vitro study of preload loss in different implant abutment connection designs
(Materials, 2022)The stability and integrity of the abutment-implant connection, by means of a screw, is fallible from the moment the prosthetic elements are joined and is dependent on the applied preload, wear of the ... -
In-vitro development of a temporal abutment screw to protect osseointegration in immediate loaded implants
(The Journal of Advanced Prosthodontics, 2015-04-23)Purpose: In this study, a temporal abutment fixation screw, designed to fracture in a controlled way upon application of an occlusal force sufficient to produce critical micromotion was developed. The ... -
Influence of bone-level dental implants placement and of cortical thickness on osseointegration: in silico and In vivo analyses
(Journal of Clinical Medicine, 2022)The purpose of this research is to study the biomechanical response of dental implants in bone-level type locations, 0.5 mm above and below the bone level. In addition, the influence of the thickness ... -
Influence of connection type and platform diameter on titanium dental implants fatigue: non-axial loading cyclic test analysis
(International Journal of Environmental Research and Public Health, 2020)Two-pieces dental implants must provide stability of the implant-abutment-interface. The connection type and platform diameter could influence the biomechanical resistance and stress distribution. This ... -
Influence of implant design and under-preparation of the implant site on implant primary stability: an In vitro study
(International Journal of Environmental Research and Public Health, 2020)The aim of this study was to evaluate the effects of different implant sites an under-preparation sequence associated with two different implant designs on implant primary stability measured by two ... -
Influence of the elastic modulus on the osseointegration of dental implants
(Materials, 2019-03-25)The load transfer from metallic prosthesis to tissue plays an important role in the success of a designed device. From a mechanical behavior point of view, the load transfer will be favored when the ... -
Influence of the titanium implant surface treatment on the surface roughness and chemical composition
(Materials, 2020)The implant surface features affect the osseointegration process. Different surface treatment methods have been applied to improve the surface topography and properties. Trace of different elements may ... -
Influence of titanium surface residual stresses on osteoblastic response and bacteria colonization
(Materials, 2024)Grit basting is the most common process applied to titanium dental implants to give them a roughness that favors bone colonization. There are numerous studies on the influence of roughness on osseointegration, ... -
Intra-osseous heat generation during implant bed preparation with static navigation: multi-factor in vitro study
