Résumé
ABSTRACT Objective: To investigate the success of implants, the increase of bone integration, and the effect of nanostructure/nanoparticles as Titanium-based implant materials on the success of implants. The present study evaluated the implant success rate of Titanium-based implant materials. Material and Methods: PICO: Population (dental implant), intervention (coated titanium implant surface), comparison (uncoated titanium implant surface), and outcome (bone-implant contact) were considered as a search strategy tool and study inclusion criteria. Searches for systematic literature were conducted on databases from Scopus, Science Direct, PubMed, ISI, Web of Knowledge, and Embase until 12 December 2022. Modified CONSORT Criteria (Reporting guidelines for preclinical in vitro studies on dental materials) were used to evaluate the quality of studies. The fixed effect model and inverse-variance method were used to calculate the 95% confidence interval for mean differences. Stata/MP V. 17 software was used to conduct the meta-analysis. Results: After reviewing the abstracts of 97 articles, studies not related to the inclusion criteria were excluded, and ten studies were selected from the remaining 39 studies after reviewing the full text. The mean difference in boneimplant contact between coated and uncoated dental implants was 0.25 (MD, 0.25 95% CI 0.01, 0.49;p=0.04). Conclusion: The titanium implant surface with nano coating can increase bone-implant contact and cause bone integration.
Résumé
Abstract Objective: To evaluate the prevalence of temporomandibular disorders (TMDs) for those patients with dentofacial deformities, who underwent orthognathic surgery, and the control group. It also identified whether orthognathic surgery had a positive or negative impact on TMD symptoms by comparing TMD patients, who underwent orthognathic surgery, and people did not experience this surgery. Finally, this systematic review and meta-analysis aimed to evaluate the effectiveness of orthognathic surgery on the pre-existing TMDs in malocclusion patients. Material and Methods: MEDLINE, PubMed, Cochrane Library, Embase, ISI, google scholar have been utilized as the electronic databases for systematically reviewing the literature between 2001 and February 2019. Inclusion criteria were undergoing orthognathic surgery, patients with/without pre-existing TMDs, and physical disabilities. Results: A total of 669 abstracts and titles with potential relevance have been identified in the course of the manual and electronic searches. It has been found that five studies met our inclusion criteria for a systematic review. Temporomandibular disorders (TMDs) before orthognathic surgery in comparison to the controls (RR=0.02; 95% CI -0.08-0.13) and heterogeneity among the papers has been I2 = 42.86% (p=0.64). Conclusion: Malocclusion by orthognathic and orthodontics surgeries had a considerable rate of TMD compared to the controls.
