OBJECTIVES
To evaluate the prevalence of proximal contact loss (PCL) between implant prostheses and natural teeth, and identify the risk factors and implications associated with PCL.
DATA/SOURCES
PubMed (MEDLINE), Google Scholar, Cochrane Library Database, Scopus, EMBASE, Open Grey, ScienceDirect, and Web of Science were electronically searched to retrieve clinical studies on PCL around implant prostheses up to September 2021.
STUDY SELECTION
A total of 19 studies were eligible. The short-term studies (less than 2 years) revealed a PCL prevalence of 11-30%, the medium-term studies (2-5 years) indicated a PCL prevalence of 13-65%, and the long-term studies (more than 5 years) showed a PCL prevalence of 29-83.3%. The likely influencing factors were the duration of service and the mesial location of proximal contacts. Other factors, such as occlusion, vitality of adjacent teeth, implant location, patient age and splinting had a less obvious relation to PCL. The reported implications of PCL were food impaction and patient dissatisfaction. Bone loss, peri-implant inflammation, bleeding on probing and pocket depth had a less clear association with PCL.
CONCLUSIONS
PCL development between implant prostheses and natural teeth is frequent, inevitable and progressive. While the review identified several influencing factors and implications of PCL, future research is needed to outline the influence of prosthesis design on PCL and food impaction.
CLINICAL SIGNIFICANCE
Patients with implant prostheses should be informed about PCL likelihood and the risk of food impaction around implant prostheses. The proximal contact quality and its implications should be monitored during the review visits.

The Journal of Prosthetic Dentistry Aug 2022Whether early loaded implants have similar clinical outcomes to delayed loaded implants is unclear. (Review)
Review
STATEMENT OF PROBLEM
Whether early loaded implants have similar clinical outcomes to delayed loaded implants is unclear.
PURPOSE
The purpose of this systematic review and meta-analysis was to compare the outcomes of early and delayed loading dental implants.
MATERIAL AND METHODS
Comprehensive searches of the MEDLINE, EMBASE, and Ovid databases were enriched by hand searches. Only human randomized controlled trials (RCTs) that compared the clinical efficacy of early and delayed loading were included. The survival rates and marginal bone level (MBL) changes were pooled and analyzed by risk ratios (RRs) and weighted mean differences (WMDs), respectively. The subgroup analyses, which were based on the Mantel-Haenszel and inverse-variance methods, included the types of prosthesis, implant time, occlusion, number of missing teeth, operation methods, dental position, healing methods, and type of first restoration. A funnel plot was used for heterogeneity analysis.
RESULTS
Eighteen trials were included from the initial 601 articles. The dental implant survival rates for the early and delayed loading were similar (P>.05). Regarding the marginal bone level changes, the 2 loading protocols also reached a comparable clinical outcome (P>.05).
CONCLUSIONS
Early implant loading should achieve the same clinical efficacy as the delayed loading method.

Review
OBJECTIVE
Bioactive glass and hydroxyapatite are biocompatible materials used as an adjunct to various dental materials. The present study aimed to evaluate the occlusion effects of bioactive glasses and hydroxyapatite on dental tubules.
MATERIALS AND METHODS
We searched the PubMed/Medline, Embase, and Web of Science databases for the relevant records. The methodological quality of the studies was assessed by an accepted quality assessment tool.
RESULTS
From the electronic databases, 372 articles were retrieved. After evaluating the records, 35 in vitro studies were included. The studies revealed a low risk of bias. The primary outcomes from bioactive glass studies demonstrated the potential efficacy of both bioactive glass and hydroxyapatite in dentin tubule occlusion compared to the control.
CONCLUSION
The current systematic review showed that bioactive glass and hydroxyapatite could effectively occlude the dentinal tubules. Thus, desensitizing agents containing bioactive glass and hydroxyapatite can be used to manage dentin hypersensitivity (DH). However, long-term follow-up clinical trials are required in the future before definitive recommendations can be made.
CLINICAL RELEVANCE
This work achieved a satisfactorily systematic review for assessing desensitizing agents containing bioactive glass and hydroxyapatite in dentine hypersensitivity treatments recommended for clinical practice and research.

Review
OBJECTIVES
To give an overview of the current evidence on the associations of general health conditions with masticatory performance and maximum bite force in older adults.
DATA/SOURCES
Three electronic databases (Medline via PubMed, Embase via Ovid and CINAHL Plus via EBSCOhost) were searched up to September 2021 for cross-sectional studies on general health conditions and masticatory performance or maximum bite force in older adults. Methodological quality of the included studies was independently evaluated based on Joanna Briggs Institute critical appraisal checklist for analytical cross-sectional studies. Data on the associations between general health conditions and masticatory performance or maximum bite force were extracted.
STUDY SELECTION
Of the 5133 records identified, 39 studies (43 articles) were included in this review. Significant negative associations were found between masticatory performance and stroke, sarcopenia, amyotrophic lateral sclerosis, chronic obstructive pulmonary disease, dyspepsia, dysphagia, anorexia, and carotid atherosclerosis. Significant negative association was found between maximum bite force and sarcopenia. There were equivocal results on the association between masticatory performance and diabetes mellitus, and between maximum bite force and stroke, and amyotrophic lateral sclerosis. There was no significant association between masticatory performance and metabolic syndrome, and between maximum bite force and progress of Parkinson's disease. Most studies revealed positive associations of physical function with masticatory performance and maximum bite force.
CONCLUSIONS
Negative associations between masticatory function of older adults and presence of several systemic diseases have been reported in a number of studies while there are positive associations between masticatory function and some physical function indicators.
CLINICAL SIGNIFICANCE
This study provides valuable information on the association of masticatory function with general health, which draws clinicians' attention to the masticatory function of older adults who suffer from certain systemic diseases or physical dysfunction, and to the need to improve their masticatory ability to achieve healthy aging.

The Journal of Contemporary Dental... Jan 2022To systematically evaluate the literature evidence regarding the suitability of the T-scan occlusal system for implant supported prostheses.
AIM
To systematically evaluate the literature evidence regarding the suitability of the T-scan occlusal system for implant supported prostheses.
MATERIALS AND METHODS
A thorough bibliographic search was conducted on PubMed, Google Scholar, Cochrane library, Web of Science, EMBASE, and Scopus to collect relevant articles published from January 1, 2008 to August 30, 2021, using a combination of the following words: "T-scan," "Implant supported prostheses," and "dental implant" according to the PRISMA guidelines for the focused research question constructed using the PICO criteria. Randomized control trials, prospective studies, retrospective studies on the use of T-scan system in implant-supported prostheses reported in English language were included in the study.
RESULTS
This review consisted of 17 studies and 359 patients rehabilitated with 1,126 implants. In 3 studies, removable types of prostheses were given over implants, and in 14 studies, fixed types of prostheses were given. Nine studies determined the percentage of occlusal force magnitude and occlusion time sequence. Three studies measured the localization of the occlusion center. T-scan was used in two studies to measure the amount of gingival crevicular fluid after occlusal adjustment. The follow-up period ranged from 6 months to 2 years or more.
CONCLUSION
T-scan proved with better results than other occlusal analysis indicators in terms of occlusion measurement, clinical execution, quantify the location and contact timing, and occlusion in 3D with more precision.
CLINICAL SIGNIFICANCE
T-scan occlusal analysis system is widely used in dentistry and there is an increase in the number of studies, so a systematic review evaluating and comparing results is warranted.

Review
OBJECTIVE
The aims of this systematic review were to evaluate the clinical masticatory performance of implant-supported restorations, observe the occlusal force changes in the distribution of the implant restoration and reveal the positive and negative contributing factors of implant design and components based on the outcomes of digital occlusal measurement.
MATERIAL AND METHODS
An extensive search was conducted through PubMed and CENTRAL to identify clinical trials on implant-retained restorations using digital occlusal analysis methods. Two researchers assessed the identified studies and data extraction independently, and the data synthesis strategies without meta-analysis that summarizes the effect estimates were adopted.
RESULTS
The search screened 3821 titles and abstracts, then full-text analysis for 26 articles was performed, and 14 studies were included in the quantitative synthesis. Four of six studies for implant-retained overdenture showed statistically significant improved bite force when immediate loading ( = .00045, .00005, .00055, and .00005, respectively), and no statistically significant results in the other two studies ( = .225, .371, respectively.) However, the results of the favoured intervention were not statistically significant ( = .104, .166, respectively) in two studies of single posterior implant restorations. In all three studies, the bite force distributed on the implant prostheses of partially fixed implant-retained restoration increased statistically significantly ( = .013, .001, .05, respectively).
CONCLUSIONS
The edentulous restoration supported by implants seems to significantly improves bite force and chewing efficiency compared with conventional dentures. Regular quantitative occlusal measurement is recommended to avoid the possible risk of overload. Smaller implants size and relatively small and flexible attachment designs may be more conducive to the stability and retention of the restoration of atrophy of alveolar bone.

Review
OBJECTIVES
The purpose of this systematic review and meta-analysis is to examine the success rate of osseointegrated dental implants placed secondarily in fibula free flaps using the Albrektsson and colleagues criteria.
MATERIAL AND METHODS
A computerized database search was performed using PubMed, Embase, Web of Science and Cochrane CENTRAL. Specific ascertainment criteria were applied for the inclusion of the eligible studies. This systematic review adhered to the Preferred Reporting Items for Systematic Reviews and Meta-analysis PRISMA checklist. Risk of bias was assessed for all the included studies.
RESULTS
The meta-analysis was carried using ten studies that met the inclusion criteria. The present review pooled data obtained from 242 patients (167 males and 75 females), with the age range of 13 to 79 years. A total of 848 dental implants were placed in the free fibula flaps. All dental implants were placed in a delayed fashion, ranging from 14 to 192 months. The estimated proportion of successful implants placed in fibula flaps used to reconstruct the maxillomandibular complex was 0.94 or 94% (95% CI [confidence interval] = 0.91 to 0.96]) with an insignificant heterogeneity of 37%, P = 0.12. Using a random effect model the annual implant failure rate was 0.02 with a 95% CI = 0.01 to 0.03.
CONCLUSIONS
The results of this systematic review and meta-analysis strongly indicate that using objective criteria, delayed implant placement in free fibula flaps is highly successful.

UNLABELLED
Some research has suggested that dental plaque and saliva could be reservoirs of () and be capable of infecting or re-infecting the gastric mucosa after eradication, with certain studies showing a significant association between PD and gastric infection by this bacterium. An electronic search was performed in PubMed, EMBASE, and Web of Science databases with the terms " AND periodontal diseases"; " AND gingivitis"; " AND chronic periodontitis"; " AND periodontitis"; " AND dental plaque", to identify articles up to September 2021. The Newcastle-Ottawa scale was used to assess study quality. A meta-analysis was performed using RevMan 2020 (Cochane Collaboration) software. A total of 1,315 studies were identified and 12 were included, analyzing 226,086 patients with mean age between 10.5 and 63.4 years. The prevalence of in the oral cavity ranged from 5.4 to 83.3%. A random-effects model was used to analyze the presence of and subgroups were made according to the method of evaluation (PCR or RUT). Statistical significance was found in the overall analysis ( = 0.01). There is no clear evidence that present in oral bacterial plaque causes gastric infection and vice versa.

Meta-Analysis Review
The aim of this systematic review was to find out if manual intraoperative control of occlusion is adequate for the reduction of mandibular fractures in comparison with intermaxillary fixation (IMF). We searched PubMed, Embase, the Cochrane Library and Clinical Trials Registry, and the references of included trials. Our primary outcomes of interest were the reduction of fracture anatomically and radiographically, occlusal disturbances, and the incidence of revision procedures due to poor occlusion or reduction. Our secondary outcomes of interest were operating time and infective complications. Of the 257 studies retrieved (manual reduction = 136, IMF = 121), four were included. The studies had an unclear risk of bias. Nevertheless, the overall effect was statistically significant and in favour of manual reduction, with a lower number of adverse events in the manual reduction group (n = 43) than in the IMF group (n = 78), odds ratio 0.42 (95% CI 0.27 to 0.64). An absolute reduction in adverse events was seen in occlusion disturbances (120 fewer/1000), revision procedures (164 fewer/1000), and infective complications (178 fewer/1000). The evidence to support manual reduction over IMF for the intraoperative control of fracture fragments and occlusion was derived from few studies with an unclear risk of bias, and the quality was low. The results were not different when condylar fractures were present. The overall certainty of evidence was moderate. Clinicians should select the appropriate technique based on the injury pattern, and the treating surgeon's experience and available resources.

Review
BACKGROUND
Bite is an important function of the human stomatognathic system. Despite this, it is commonly impaired in temporomandibular disorder (TMD) populations. The aim of this review is to evaluate the effectiveness of conservative interventions on self-reported and physical measures of bite function in individuals with TMD.
METHODS
This review was performed in compliance with PRISMA guidelines. An electronic search was performed on databases including PubMed, CINAHL, Embase, and Cochrane Central. Inclusion criteria were journal articles evaluating the effect of any non-pharmacological conservative interventions on bite function in participants diagnosed with TMD. Risk of bias for individual studies was assessed using the Cochrane risk-of-bias v2 tool, and the NIH NHLBI pre-post tool. Data was synthesised based on outcome measures of bite function, and the quality of evidence was assessed using the Grading of Recommendations Assessment, Development and Evaluation approach.
RESULTS
Eleven studies were eligible for this review. Interventions included splinting, photobiomodulation, needling, exercise, manual therapy, and patient education, which were evaluated using mastication-related pain, self-reported chewing difficulty, and bite force/endurance outcome measures. Findings suggested manual therapy, needling, oral splinting, exercise, and PBM interventions may improve bite function in TMD, although confidence in cumulative evidence ranged from moderate to very low. There was no evidence that patient education improved bite function.
CONCLUSION
Conservative interventions may be helpful to address bite-related impairments associated with TMD, although further research is needed to improve the quality of evidence and direct clinical guidelines.
