Introduction: In the context of implant dentistry, dental implants represent about 1,000,000 procedures per year worldwide. Virtual implant planning systems integrate cone beam computed tomography (CT) data to assess the amount of bone and virtual models for the project of a dental implant. Objective: It presented, through a systematic review, the main considerations of guided surgery in implant dentistry through evidence from clinical studies and important systematic reviews on the subject. Methods: The research was carried out from May 2021 to June 2021 and developed based on Scopus, PubMed, Science Direct, Scielo, and Google Scholar, following the Systematic Review-PRISMA rules. The quality of the studies was based on the GRADE instrument and the risk of bias was analyzed according to the Cochrane instrument. Results: A total of 112 articles were found on guided surgery and implantology. Initially, duplication of articles was excluded. In total, 54 articles were fully evaluated and 23 were included and evaluated in this study. In the GS scenario, advances in technology have contributed to the improvement of models with favorable positioning of implants in aesthetic terms. This provides the predictability of techniques and difficulties that may be encountered during surgical intervention, reducing time and the possibility of errors, allowing for an overall reduction in the costs of oral rehabilitation. Conclusion: Guided surgery is considered accurate and reliable compared to free implant surgery. However, the learning curve is undeniable and a clinician with basic surgical skills, including conventional implant dentistry.

Introduction: In the landscape of new digital technologies, many dental treatments have benefited from this digital advance. The development of computed tomography (CT) dental scanners has enabled powerful imaging capabilities and software applications. The prosthetic plane and implanted drill guides with the placement of trajectories based on a drill according to the position of the CT 3-D Space markers. Objective: To present, through a systematic review, the main considerations of guided surgery in implant dentistry and its respective advantages, disadvantages, and limitations. Methods: Clinical studies with qualitative and/or quantitative analysis were included, following the rules of the systematic review-PRISMA. Results: Out of a total of 102 articles found, 82 articles were evaluated and 57 were rejected for not meeting the GRADE classification, and only 25 articles were used in this study to compose the textual part. Advances in technology have contributed to the improvement of implant models. 3D reconstructions make it possible to determine the quantity and quality of available bone and also enable the simulation of implant installation in a virtual environment, reducing time and the possibility of errors, allowing for an overall reduction in the costs of oral rehabilitation. Conclusion: Guided preoperative planning or project-guided dental surgery provides high implant and dental rehabilitation success rates, also benefiting prosthetic restorations supported by fixed implants. Furthermore, the concept of using personalized implants with the help of 3D virtual treatment planning improves mandibular restoration with a good facial profile, esthetics, and dental rehabilitation.

Study Design: Systematic review. Objectives: The primary objective of this systematic review was to define the change in impairment, disability, and pain following surgical intervention in patients with degenerative cervical myelopathy (DCM). Secondary objectives included to assess the impact of preoperative disease severity and duration of symptoms on outcomes and to summarize complications associated with surgery. Methods: A systematic literature search was conducted to identify prospective studies evaluating the effectiveness and safety of operative treatment in patients with DCM. Outcomes of interest were functional status, disability, pain, and complications. The quality of each study was evaluated using the Newcastle-Ottawa Scale, and the strength of the overall body of evidence was rated using guidelines outlined by the Grading of Recommendation Assessment, Development and Evaluation (GRADE) Working Group. Results: Of the 385 retrieved citations, 32 met inclusion criteria and are summarized in this review. Based on our results, pooled standard mean differences showed a large effect for improvement in Japanese Orthopaedic Association or modified Japanese Orthopaedic Association score from baseline at short-, medium-, and long-term follow-up: 6 to 12 months (1.92; 95% confidence interval [CI] = 1.41 to 2.43), 13 to 36 months (1.40; 95% CI = 1.12 to 1.67), and ≥36 months (1.92; 95% CI = 1.14 to 2.69) (moderate evidence). Surgery also resulted in significant improvements in Nurick, Neck Disability Index, and Visual Analogue Scale scores (low to very low evidence). The cumulative incidence of complications was low (14.1%; 95% CI = 10.1% to 18.2%). Conclusion: Surgical intervention for DCM results in significant improvements in functional impairment, disability, and pain and is associated with an acceptably low rate of complications.

The purpose of this review is to examine various assessment methods in order to compare the accuracy between the virtually planned and clinically achieved implant positions. In this review, comparison methods using pre- and post-operative computed topography (CT) data and digital impressions for definitive prosthesis will be described. The method for the displacement and strain for quantification of the error will also be explored. The difference between the planned and the actual implant placement position in guided implant surgery is expressed as an error. Assessing the accuracy of implant-guided surgery can play an important role as positive feedback in order to reduce errors. All of the assessment methods have their own inevitable errors and require careful interpretation in evaluation.

ObjectiveTo assess the benefit of arthroscopic partial meniscectomy (APM) in adults with a meniscal tear and knee pain in three defined populations (taking account of the comparison intervention): (A) all patients (any type of meniscal tear with or without radiographic osteoarthritis); (B) patients with any type of meniscal tear in a non-osteoarthritic knee; and (C) patients with an unstable meniscal tear in a non-osteoarthritic knee.DesignSystematic review and meta-analysis.DatasourcesA search of MEDLINE, Embase, CENTRAL, Scopus, Web of Science, Clinicaltrials.gov and ISRCTN was performed, unlimited by language or publication date (inception to 18 October 2018).EligibilitycriteriaRandomised controlled trials performed in adults with meniscal tears, comparing APM versus (1) non-surgical intervention; (2) pharmacological intervention; (3) surgical intervention; and (4) no intervention.ResultsTen trials were identified: seven compared with non-surgery, one pharmacological and two surgical. Findings were limited by small sample size, small number of trials and cross-over of participants to APM from comparator interventions. In group A (all patients) receiving APM versus non-surgical intervention (physiotherapy), at 6–12 months, there was a small mean improvement in knee pain (standardised mean difference [SMD] 0.22 [95% CI 0.03 to 0.40]; five trials, 943 patients; I248%; Grading of Recommendations Assessment, Development and Evaluation [GRADE]: low), knee-specific quality of life (SMD 0.43 [95% CI 0.10 to 0.75]; three trials, 350 patients; I256%; GRADE: low) and knee function (SMD 0.18 [95% CI 0.04 to 0.33]; six trials, 1050 patients; I227%; GRADE: low). When the analysis was restricted to people without osteoarthritis (group B), there was a small to moderate improvement in knee pain (SMD 0.35 [95% CI 0.04 to 0.66]; three trials, 402 patients; I258%; GRADE: very low), knee-specific quality of life (SMD 0.59 [95% CI 0.11 to 1.07]; two trials, 244 patients; I271%; GRADE: low) and knee function (SMD 0.30 [95% CI 0.06 to 0.53]; four trials, 507 patients; I244%; GRADE: very low). There was no improvement in knee pain, function or quality of life in patients receiving APM compared with placebo surgery at 6–12 months in group A or B (pain: SMD 0.08 [95% CI −0.24 to 0.41]; one trial, 146 patients; GRADE: low; function: SMD −0.08 [95% CI −0.41 to 0.24]; one trial, 146 patients; GRADE: high; quality of life: SMD 0.05 [95% CI −0.27 to 0.38]; one trial; 146 patients; GRADE: high). No trials were identified for people in group C.ConclusionPerforming APM in all patients with knee pain and a meniscal tear is not appropriate, and surgical treatment should not be considered the first-line intervention. There may, however, be a small-to-moderate benefit from APM compared with physiotherapy for patients without osteoarthritis. No trial has been limited to patients failing non-operative treatment or patients with an unstable meniscal tear in a non-arthritic joint; research is needed to establish the value of APM in this population.Protocol registration numberPROSPERO CRD42017056844.

OBJECTIVE: The aim of this study was to analyze the relationship between cognition and frailty in the elderly. METHODS: A systematic review on the currently existing literature concerning the subject was carried out. The search strategy included LILACS, SCOPUS, SciELO, PsycINFO, PubMed and Web of Science databases. RESULTS: A total of 19 studies were selected for review, from which 10 (52.6%) were cross-sectional and 9 (47.4%) longitudinal, and the majority Brazilian. All of the studies established a link between cognition and frailty. There was a relationship between components of frailty and the cognitive domains. Risk of Mild Cognitive Impairment (MCI), dementia and mortality were all evidenced in the relationship between frailty and cognitive impairment. CONCLUSION: The theory remains limited, but results show the variables that appear to be linked to cognition and frailty in elderly. This data can help in implementing actions to improve the quality of life among elderly.

Introduction. The aim of this study is to compare the quality of life (QoL) in partially edentulous osteoporotic women who have missing teeth restored with dental implant retained restorations with those who do not and, secondarily, to report the rate of osteonecrosis in this sample.Methods. 237 participants completed the Utian QoL survey, a 23-question document measuring across psychosocial domains of well-being including occupational, health, emotional, and sexual domains which together contribute to an overall score. The subset of participants having dental implant supported prosthesis (64) was compared to the subset having nonimplant supported fixed restorations (47), the subset having nonimplant supported removable restorations (60), and the subset having no restoration of missing teeth (66).Results. ANOVA showed significant difference in all QoL domains between the four subsets(p<0.05). Although 134 reported oral bisphosphonate and 51 reported IV bisphosphonate use, no signs of ONJ were identified in any participants.Conclusion. These findings show implant retained oral rehabilitation has a statistically significant impact over nonimplant and traditional fixed restorations, removable restorations, and no restoration of missing teeth in far reaching areas including occupational, health, emotional, sexual, and overall QoL. These findings also support future examination of psychosocial outcomes associated with oral rehabilitation and the incorporation of oral health into women’s health promotion.

Abstract Aim The use of augmented and mixed reality technology is a novel and rapidly developing field. This technology has generated significant interest in surgery, however the evidence supporting its proposed benefits is limited. This systematic review aims to critically appraise the intraoperative use of augmented and mixed reality technology to improve surgical outcomes in order to provide directions for future research. Method This systematic review is registered with PROSPERO (CRD42020205892) and was performed in adherence to PRISMA guidelines. Studies reporting primary data on surgical outcomes of the intraoperative use of augmented and mixed reality technology were included. A structured search of major literature databases was performed. Risk of bias was assessed following the guidance of the Cochrane Handbook. Results 68 studies met the inclusion criteria, with 63 reporting the intraoperative use of augmented reality technology and 5 reporting the use of mixed reality. The number and methodological quality of these studies is increasing. The intraoperative use of this technology has been demonstrated to reduce operative times, intraoperative blood loss and lengths of hospital admissions in specific settings. The widespread adoption of this technology faces the challenges of its cost, technical precision and integration into the surgical workflow. Conclusions The intraoperative use of augmented and mixed reality technology is an area of research still in its early stages, with an increasing number of methodologically robust studies on the subject. Current results suggest that the use of this technology is safe and, in certain applications, has the potential to significantly improve surgical and health-economic outcomes.
