“…Generally, surface treatment did not influence primary stability, as the implants behavior upon analysis was very similar among every substrate used. This shows the influence that the type of material into which an implant is placed may have on results, being, in this study, more prevalent than the influence of the presence of surface treatment and corroborating the systematic review by Marquezan et al 26 , who observed positive correlation between primary stability -assessed by several methods, including resonance frequency -and bone mineral density. This also corroborates the study by Kumar et al 11 who found that, in ex vivo bone samples with lower values of ultrasound transmission speed, a method used to assess bone quality, lower primary stability values were observed.…”

Objective The aim of this study was to analyze the primary stability of dental implants with and without surface treatment, by means of resonance frequency, using different materials as substitutes for human bone substrates for insertion. Methods Sixteen external hexagon, cylindrical RESUMO ObjetivoAnalisar a estabilidade primária de implantes odontológicos com tratamento e sem tratamento de superfície, por meio da frequência de ressonância, utilizando diferentes materiais como substratos substitutos do osso humano para sua inserção. MétodosForam utilizados 16 implantes de titânio Conexão ® , cilíndricos, hexágono externo, com 11,5 mm de comprimento e 3,75 mm de largura, sendo: 8 Master Porous, com tratamento de superfície; e 8 Master Screw, usinados. A instalação de implantes foi realizada nos seguintes substratos: osso de costela suína, madeira, osso artificial de poliuretana da marca Nacional ® (40, 20 e 15 PCF) e da marca Synbone ® . Foi avaliada a estabilidade primária através da frequência de ressonância utilizando o aparelho Osstell™ Mentor. Os dados obtidos foram submetidos a tratamento estatístico ANOVA e Teste de Tukey, com nível de significância a 5%. ResultadosFoi constatado que, apesar de Master Porous apresentar maior valor que Master Screw em todos os substratos, estes não apresentaram diferença estatística entre si (p>0,05), com exceção da poliuretana Nacional ® de 20 PCF. Quando inseridos no substrato madeira e na poliuretana Nacional ® 40 PCF, Master Porous e Master Screw tiveram maiores valores. Master Porous, quando inserido no osso suíno também foram iguais estatisticamente a estas interações. ConclusãoApesar de inovações nas características das superfícies de implantes serem desenvolvidas constantemente para contribuir no desempenho de implantes osseointegrados, e nosso estudo encontrar que não houve influência do tratamento de superfície na estabilidade primária aferida por frequência de ressonância; ainda há pouco conhecimento científico sobre esses efeitos.Termos de indexação: Densidade óssea.

The aim of this study was to evaluate the effect of pitch distance on the primary stability (PS) of orthodontic mini-implants (MIs) in artificial bone. Twenty experimental MIs were allocated to two groups, according to their geometric design: G 1 (30 o X 0.6 mm) and G 2 (45 o X 0.8 mm), and inserted into artificial bone of different densities: D 1 (0.32 g/cm ). The maximum insertion torque (IT) and removal torque (RT) values were recorded in N.cm. Loss of torque (LT) values were obtained by calculating the difference between the IT and RT. MI mobility was measured by means of a Periotest assessment. Normality and homogeneity were determined by means of the Kolmogorov-Smirnov and Shapiro-Wilk tests, respectively. A two-way ANOVA was used to detect differences between the mini-implant design and density factors. The ANOVA/ Tukey tests were used to determine the intergroup difference. Higher IT values were observed for G 2 (p ≤ 0.05) in D 2 . No statistical difference for RT was observed between the groups, whereas G 2 presented higher values only for LT (p ≤ 0.05). The Periotest values (PTV) were higher for G 1 , in comparison with G 2 , in D 1 . G 1 presented better PS in D 2 (IT, RT and LT), whereas G 2 was found to be more stable in D 1 , after evaluation with Periotest.

An overview of professional literature referring to the release of metal ions from fixed orthodontic appliances and their influence on oral mucosa in conditions of in vivo are presented, along with a detailed analysis of the exposure of the cells of cheek mucosa epithelium to metal ions. Electronic databases (PubMed, Elsevier, Ebsco) were searched with no language restrictions. The relevant orthodontic journals and reference lists were checked for all eligible studies. A total of 38 scientific articles were retrieved in the initial search. However, only 7 articles met the inclusion criteria. Statistically significant differences in the levels of the amount of nickel ions, cobalt ions and chromium ions were observed in cells of cheek mucosa. The most biocompatible material used in the production of fixed orthodontic appliances is titanium, and the least biocompatible material is steel, which releases the largest amount of nickel and chromium. Metal ions are released from fixed orthodontic appliances only in the first phase of treatment. It is recommended to conduct further, long-term research on a larger number of patients to define the influence of using fixed orthodontic appliances and biological effect they might have on tissues.

Does bone mineral density influence the primary stability of dental implants? A systematic review

Abstract: There is a positive association between implant primary stability and bone mineral density of the receptor site. However, the methodological quality and control of bias of the studies should be improved to produce stronger evidences.
