“…In recent years, similar studies have been published in which implant stability is assessed with different implant designs or even with different implant concepts, such as bone level and tissue level. The purpose of this study was to evaluate the design modifications, mainly on the implant core, combining with under-preparation of the implant bed and its influence on the primary stability [42][43][44].…”

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 parameters: insertion torque (IT) and implant stability quotient (ISQ). It used two different implants: one cylindrical as a control and another one with a tapered design. The implants were inserted in type III fresh humid bovine bone and four drilling sequences were used: one control, the one proposed by the implant company (P1), and three different undersized (P2, P3 and P4). P2 was the same as P1 without the cortical drill, P3 was without the last pilot drill and P4 was without both of them. The sample size was n = 40 for each of the eight groups. Final IT was measured with a torquemeter and the ISQ was measured with Penguin resonance frequency analysis. Results showed that both ISQ and IT have a tendency to increase as the preparation technique reduces the implant site diameter when compared with the standard preparation, P1. The preparations without cortical drill, P2 and P4, showed the best results when compared with the ones with a cortical drill. Tapered implants always showed higher or the same ISQ and IT values when compared with the cylindrical implants. Giving the limitations of this study, it can be concluded that reducing implant preparation can increase IT and ISQ values. Removing the cortical drill and the use of a tapered design implant are also effective methods of increasing primary implant stability.

“…Primary stability was initially evaluated using invasive methods, such as assessing the insertion and disinsertion torque of the implant with a torque gauge or torque wrench during implant insertion [6]. Another noninvasive method, resonance frequency analysis (RFA), was also employed because of its reliably, repeatability and relation with micromovements [7][8][9][10]. However, both techniques were confirmed to analyze different mechanical aspects of the implant stability concept [11].…”

As immediate loading protocols are becoming more frequent, the primary stability of implants has become an essential criterion for the osseointegration of dental implants. Based on this, the objective of this study was to understand the influence of different undersized surgical preparation sites on the insertion torque (IT) and implant stability quotient (ISQ). Four different site-preparation protocols were performed on fresh humid type III bovine bone: one control, the standard protocol recommended by the manufacturer (P1), and three variations of undersized techniques (P2, P3 and P4). The implant used was VEGA by Klockner Implant System. The sample size was n = 40 for each of the four groups. A torquemeter was used to measure the IT, and the ISQ was measured with a Penguin RFA. Both variables showed a tendency to increase as the preparation technique was reduced, although not all the values were statistically significant (p < 0.05) when comparing with the standard preparation. The preparations without a cortical drill, P2 and P4, showed better results than those with a cortical drill. Given the limitations of this study, it can be concluded that reducing the implant preparation can increase both the IT and ISQ. Removing the cortical drill is an effective method for increasing implant stability, although it should be used carefully.

“…A estabilidade primária pode ser definida como a fixação inicial no momento de instalação do implante no osso obtida e mensurada de várias maneiras (Mantovani et al, 2018;Herrero-Climent et al, 2019), tornando-se assim importante para o sucesso da osseointegração e determinação de protocolos para reabilitações protéticas. A qualidade, a densidade e o volume ósseo são alguns dos fatores que influenciam diretamente, bem como, o desenho do implante e o torque de inserção dado ao implante.…”

“…Vários são os estudos que mostraram a utilização, a confiabilidade, a reprodutibilidade e repetibilidade dos resultados com o uso do Osstell ® ISQ para a verificação do quociente de estabilidade dos implantes, tanto primária como secundária (Andreotti et al, 2017;Becker et al, 2018;Buyukguclu et al, 2018;Herrero-Climent et al, 2019), alguns autores ainda relacionaram vários métodos de análise de frequência de ressonância dos implantes, relacionando-os e mostrando a eficácia e confiabilidade destes (Becker et al, 2018;Buyukguclu et al, 2018;Herrero-Climent et al, 2019).…”

“…Apesar de todas as vantagens e benefícios comprovados da utilização da PBMT na reparação dos tecidos e da confiabilidade da utilização do Osstell ® ISQ (Andreotti et al, 2017;Becker et al, 2018;Buyukguclu et al, 2018;Herrero-Climent et al, 2019), os nossos resultados estão de acordo com os resultados de vários autores que apresentaram respostas clínicas estatistamente não significantes, quando comparados de forma randomizada os diferentes lados no mesmo paciente, onde num lado foi aplicado a PBMT e o outro não (Barbosa et al, 2013;Manzano-Moreno et al, 2015;Kim et al, 2016;Becker et al, 2018), porém concordamos com os autores que sugerem que mais pesquisas semelhantes são necessárias para determinar um protocolo de análise de frequência de ressonância para a verificação da osseointegração dos implantes.…”

Grande amigo! ABSTRACT Sampaio RMF. Evaluation of the stability of osseointegrated implants in alveolus, with and without the application of Photobiomodulation Therapy, using Osstell® ISQ: clinical trial, double blind and randomized [thesis]. São Paulo: Universidade de São Paulo, Faculdade de Odontologia; 2020. Versão Corrigida.The primary stability of the implants is a very important step that can become a determining factor in the success of prosthetic rehabilitation. The integration between bone tissue and implants takes a certain amount of time to occur. Certain kinds of therapy can be used in order to decrease and accelerate this osseointegration time. In our study, 20 patients who required extraction on bilateral lower molars were selected.The extractions were performed at the same surgical moment, where one side was the control and the other received Photobiomodulation Therapy (PBMT) at different moments: immediately after surgery, after 24, 48, 72, 96 hours, and 7 and 15 days (the application of PBMT followed the blinding protocol). After 45 days of extractions, the implants were installed and their primary stability was assessed by the Resonance Frequency Analysis (RFA) using Osstell®️ (on the ISQ scale). After 90 days of implant placement, at the time of reopening, stability measurement was performed again with Osstell®️ ISQ. According to the figures obtained, statistical tests of mean, standard deviation, paired t-test on the control side and on the side where PBMT was applied, were performed at both times (when the implants were installed and after 90 days) of all the research patients. We concluded t...
