13. Does traumatic occlusal forces lead to peri-implant bone loss? A systematic review
Abstract Observational studies have indicated that crestal bone level changes at implants are typically associated with clinical signs of inflammation, but still mechanical overload has been described as possible factor leading to hard–tissue deficiencies at implant sites without mucosal inflammation. The aim of this paper was systematically review the lit

14. Biomechanics of extra-alveolar mini-implants
RESUMO É inegável que a ancoragem com mini-implantes extra-alveolares revolucionou a nossa especialidade. No mesmo sentido, o correto entendimento da biomecânica com mini-implantes permitiu ampliar a gama de movimentos dentários como nunca visto na prática clínica. Deve-se, porém, atentar às diversas possibilidades dos sistemas de aplicação das for

15. Influence of Abutment Collar Height and Implant Length on Stress Distribution in Single Crowns
Resumo Este estudo avaliou a influência da altura da porção transmucosa do pilar protético com junção cone morse e do comprimento dos implantes no comportamento biomecânico coroas unitárias com diferentes proporção coroa-implante. Seis modelos virtuais (S11, M11, L11, S13, M13 e L13) foram construídos combinando pilares protéticos com transmucoso

16. On Estimation of Adhesive Strength of Implants Bioactive Coating with Titanium by Density Functional Theory and Molecular Dynamics Simulations
One of the ways to improve and accelerate osseointegration of a surgical implant with bone is application of biocompatible coatings, in particular, hydroxyapatite (HAp). Since the cases of delamination of the coating take place in dental practice, it is very important to estimate the adhesive strength of HAp with the implant. A measure of the coating-to-subs

17. Dental implant surfaces treated with phosphoric acid can modulate cytokine production by blood MN cells
Abstract: The study characterizes dental implant surfaces treated with phosphoric acid to assess the effects of acid treatment on blood cells and correlate them with cytokine levels. The implant surfaces examined were divided into untreated metal surface (US; n = 50), metal surface treated with phosphoric acid (ATS; n = 50) and cement surface (CS; n = 50) gr

18. Risk factors associated with short dental implant success: a long-term retrospective evaluation of patients followed up for up to 9 years
Abstract: This multicenter study aimed to identify the different implant- and patient-related risk factors for long-term short dental implant success. Through a retrospective chart review of three centers, patient information regarding demographic variables, smoking habits, history of periodontitis, systemic diseases, and medications in addition to the param

20. RADIOACTIVE CEMENT OF PMMA AND HAP-Sm-153, Ho-166, OR RE-188 FOR BONE METASTASIS TREATMENT
RESUMO Polymethylmetacrylte (PMMA) é um composto utilizado na indústria e desde os anos 80's também tem sido empregado nas áreas odontológica e biomédica como constituinte de cimentos ósseos. A hydroxyapatite (HAp) é uma biocerâmica produzida naturalmente nos ossos. Esses dois componentes são constituintes fundamentais no preparo de cimentos ósseo

21. Semi-solid Sintering of Ti6Al4V/CoCrMo Composites for Biomedical Applications
A composite of Ti6Al4V reinforced with CoCrMo particles is fabricated by conventional powder metallurgy and semi-solid sintering. Composites are fabricated by mixing 20% wt. of CoCrMo reinforcing particles into the Ti6Al4V matrix. Sintering is studied by dilatometry tests between 1050 and 1130 °C and compact characterization is performed by SEM and XRD. Mic

22. Can implant surfaces affect implant stability during osseointegration? A randomized clinical trial
Abstract This randomized clinical trial evaluated the insertion torque (IT), primary, and secondary stability of dental implants with different surface treatments during the osseointegration period. Nineteen patients with bilateral partial edentulism in the posterior mandibular region were randomly allocated to two implant brand groups and received implants

23. Short implants versus longer implants with maxillary sinus lift. A systematic review and meta-analysis
Abstract This study compared the survival rate of dental implants, amount of marginal bone loss, and rates of complications (biological and prosthetic) between short implants and long implants placed after maxillary sinus augmentation. This systematic review has been registered at PROSPERO under the number (CRD42017073929). Two reviewers searched the PubMed/

24. Estudio de los parámetros de proceso del anodizado por plasma químico en Ti-6Al-4V ELI para implantes dentales
ABSTRACT In order to study the variation effect of some parameters of micro-arc oxidation process (MAO) on Ti-6Al-4V samples for dental implants, several treatments were carried out under different conditions of current density, exposure time and electrolyte chemical composition. These processes resulted in generated bioactive titanium oxide surface coatings
