Background The influence of using different insertion torque values on clinical and radiographic outcomes of implant therapy is unclear in the current literature. The aim of this systematic review and meta‐analysis was to evaluate the implant outcomes and complications rates using high insertion torque values compared with those using regular insertion torque value levels. Methods Randomized controlled trials (RCTs), nonrandomized controlled clinical trials (NRCCTs), prospective and retrospective cohorts were searched for in electronic databases and complemented by hand searching relevant dental journals. The risk of bias was assessed using the Cochrane Collaboration's Risk of Bias tool for randomized and nonrandomized studies. Data were analyzed using a statistical software. Results A total of 718 studies were identified, of which, nine studies were included with 1229 dental implants in 684 participants. The meta‐analysis of RCTs showed that the overall implant failure rate was not notably in favor of any insertion torque value and the difference between the two groups was not statistically significant (risk ratio 0.85; 95% confidence interval 0.07–10.52; P = 0.90). None of the RCTs was registered. The secondary analyses of non‐RCTs did not either show any statistically significant difference. Overall meta‐analysis did not show any significant differences in peri‐implant marginal bone loss or biological/technical complications between high (≥50 Ncm) and regular insertion torque (<50 Ncm). Conclusions There is insufficient evidence to support the use of high or regular insertion torque even with immediate implant restoration/loading. The short‐term implant failure rates, changes in marginal bone level and complication rates were comparable when high or regular insertion torques were used for implant placement. The wide confidence interval indicated that results cannot be interpreted with clinically meaningful benefit for using either high or regular insertion torque.

“…Osseointegration can be assessed through intraosseous implant stability using Xray [14,49]. In this study, the absence of radiolucency as a sign of bone resorption surrounding the implant demonstrates the stability of the intraosseous implant that was observed 6 months after placement.…”

In this study, the innovative dip-coating technique treated titanium (IDCT-Ti) implant with tetrapeptide Gly-Arg-Gly-Asp (GRGD) coating was investigated for its potential to enhance osseointegration. The L929 fibroblast cells were cultured in different concentrations of the GRGD (1%, 2%, and 5%). The cell viability was assessed through 3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyltetrazolium bromide (MTT) assay and live/dead staining. The surface topography and nano-indentation were analyzed by atomic force microscopy. The hemocompatibility was evaluated via field-emission scanning electron microscopy, while contact angle analysis was detected by a goniometer. Radiograph evaluation was determined by panoramic imaging. It was found that the cell growth increased and had a survival rate of more than 70% in 1% GRGD. The mortality of L929 increased with the higher concentration of GRGD. The IDCT-Ti coated with 1% GRGD showed a nano-surface with a Young’s modulus that was similar to human cortical bone, and it displayed greater red blood cell accumulations with abundant fibrin formation. As regards the wettability, the IDCT-Ti coated with 1% GRGD was lower than the SLA (sandblasted, large-grit, and acid-etched) treated implant. The X-ray image exhibited no bone loss around the implant at six months after placement. As a result, this study suggests that the IDCT-Ti implant, coated with 1% GRGD, has a tremendous likeliness to enhance osseointegration.

“…3 Recently, with the rapid progress that accompanied the implant and the improvements made to the implant surfaces, the practitioner became able to shorten the treatment period and restore functional and cosmetic aspects in less time, improving patient satisfaction and acceptance rate. 26 Thus, immediate and early loading has become a desirable target in most cases.…”

Aim The goal of this study was to evaluate how early loading of dental implants, both functional and non‐functional, can affect the stability of the implants, marginal bone resorption after 1 year of follow‐up. Material and Methods The research sample consisted of 24 implants placed on patients aged between 21 and 62 years (the mean age 51 years). Implants were placed at one surgical stage in the posterior area of the mandible. Then implants were loaded early after 6 weeks of implantation. The sample was divided randomly into two equal main groups according to loading types, 12 implants in the early functional loading (EFL) group and 12 implants in the early non‐functional loading (ENFL) group. The implant stability quotient was registered using Osstell Mentor at the implant placement procedure and after 6 and 12 weeks. The mean marginal bone loss around the implants was measured using the periapical radiographs after 3 and 12 months. The mean values were calculated and statistically analysed using the two‐sample t‐test with 95%confidenence interval p < 0.05). Result The mean values of implant stability quotient (ISQ) were 72.91–73.87–76.75 in the EFL and 71.91–73.91–76.66 in the ENFL, at the implant placement procedure and 6, 12 weeks respectively. There was no statistically significant difference (p < 0.05) between the two groups. At the 12‐month post‐loading follow‐up, the mean marginal bone loss was 0.698 for the EFL group and 0.683 for the ENFL group. There was no statistically significant difference (p < 0.05) between the two groups. The implant survival rate was 100% in both groups, and there was no complication during the follow‐up period. Conclusions This study showed that there is no difference in the implant stability quotient (ISQ) and bone loss between the early functional loading group and the early non‐functional loading group.
