Effect of three-dimensional print angle on integrity of interim crowns: A systematic review.

STATEMENT OF PROBLEM: Three-dimensional printing is a rapid and cost-effective method that eliminates material waste during the manufacture of indirect restorations. Parameters such as print angle significantly affect the physical properties of the printed material. Several manufacturers suggest using an angle of 45 degrees to perform printing; however, different angles have been used, and the optimum parameters are unclear. PURPOSE: The purpose of this systematic review was to compare the 45-degree print angle with other protocols and evaluate the effect of print angle on the physical and mechanical material properties. MATERIAL AND METHODS: Two researchers independently searched for relevant studies published up to June 2023 in the PubMed/MEDLINE, Scopus, Web of Science, and Lilacs electronic databases. The population, intervention, comparison, outcome (PICO) question was: "Does the 45-degree print angle promote better physical characteristics for 3-dimensionally printed interim crowns?" Studies that compared the properties of the different print angles of interim crowns were analyzed. RESULTS: Ten in vitro studies were selected for qualitative analysis. When evaluating marginal and internal fits, most studies selected the 45-degree angle, resulting in less discrepancy. The results of flexural strength analysis showed a high level of heterogeneity. The 0-degree print angle yielded better results in 3 studies, followed by the 90-degree print angle in 2 studies. The 45-degree angle yielded the highest fracture resistance value in 1 study and similar results to those of the control group (milled PMMA) in another study. CONCLUSIONS: The marginal and internal adaptation and resistance to flexure of printed interim crowns are satisfactory when a 45-degree print angle is used.

Is Muscle Pain in Temporomandibular Disorder a Hyperactivity Problem? A Clinical, Thermographic, and Electromyographic Analysis.

ABSTRACT: This study aimed to report clinical data on muscle pain in temporomandibular disorders using thermography, algometry, and surface electromyography (EMG). This was done to support or rule out the hypothesis that painful muscles are always related to muscular hyperactivity. This cross-sectional, analytical study included 50 participants who underwent clinical examination and evaluation of anterior temporal muscles and bilateral masseters using thermography, algometry, and EMG. The muscles with greater pain symptoms had hyporadiation and a lower temperature compared with both contralateral muscles and muscles in the asymptomatic group. There was no muscle hyperactivity at rest on EMG analysis; however, there was a greater capacity for muscle recruitment of these symptomatic muscles after a joint decompression test with cotton rolls, suggesting hypoactivity of the affected muscles in the symptomatic patient group. Muscle pain may be related to hypoactivity of the musculature when there is neurological inhibition of the recruitment of muscle fibers, and treatment must consider these neurophysiological alterations. LEVEL OF EVIDENCE: Level IV.

Profile of Facial Trauma Victims of Motorcycle Accidents: A Prospective Study.

OBJECTIVE: To outline the profile of patients with facial trauma, victims of motorcycle accidents, treated at the Hospital da Restauração, Recife/PE, Brazil, from December 2020 to July 2021. METHODS: The collection was carried out through questionnaire and analysis of medical records. Data were analyzed descriptively, as well as Pearson's chi-square test or Fisher's exact test. RESULTS: Among the patients, 88.6% were male, 47.5% were between 18 and 29 years old, and 59.6% lived in rural areas; 72.15% of the victims used the motorcycle for work and 43.52% were working at the time of the accident. Most victims did not have a national motorcycle license (62%) and were not wearing a helmet at the time of the accident (60%), with 37.6% wearing a full-face helmet, 16.5% an open helmet, and 5.9% an articulated full-face helmet. Soft tissue injuries were the most prevalent. Zygomatic complex fractures were the most common facial fractures and were significantly associated with helmet use and type. CONCLUSIONS: Most victims of motorcycle accidents are young adult men, without a regular driver's license and residing in rural areas. Preventive and educational actions and continuous traffic inspections are necessary to minimize these accidents.

Evaluation of Masticatory Function, Satisfaction, and Quality of Life Among Users of Complete Dentures Relined with Resilient Materials: A Systematic Review.

PURPOSE: To evaluate whether complete dentures (CDs) relined with long-term resilient liners (LTRLs) favor better masticatory function, satisfaction, and quality of life among completely edentulous patients compared to conventional CDs. MATERIALS AND METHODS: This review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) checklist and was registered in PROSPERO (the International Prospective Register of Systematic Reviews; CRD42021258700). The population, intervention, comparison, and outcome (PICO) purpose was to determine whether CDs relined with LTRLs favor better masticatory function, satisfaction, and quality of life among completely edentulous patients when compared to CDs. Searches were performed in the PubMed/MEDLINE, Embase, Scopus, Lilacs, BBO, and OpenGrey databases. Manual searches were also performed to identify additional primary studies. RESULTS: Overall, 3,953 articles were found. After removing duplicates, reading the articles, and applying the inclusion and exclusion criteria, 15 articles were selected for qualitative analysis, totaling 422 patients with follow-up periods ranging from 1 week to 3 years. Among these, 8 studies assessed masticatory function using different methods, 2 assessed satisfaction, 1 assessed quality of life, and 4 assessed more than one outcome. Through qualitative analysis, LTRLs showed satisfactory results in most studies when compared to CDs in relation to masticatory function, satisfaction, and quality of life. CONCLUSIONS: LTRLs favor better masticatory function, satisfaction, and quality of life among completely edentulous patients compared to CDs.

Clinical performance and patient-related outcome measures of digitally fabricated complete dentures: A systematic review and meta-analysis.

STATEMENT OF PROBLEM: The demand to streamline workflow while increasing patient comfort and satisfaction in the manufacturing of removable complete dentures (CDs) is growing, and computer-aided design and computer-aided manufacturing (CAD-CAM) technology has gained prominence. However, a systematic review and meta-analysis of the clinical performance and patient-related outcome measures (PROMs) of digitally fabricated complete dentures is lacking. PURPOSE: The purpose of this systematic review and meta-analysis was to determine whether digitally fabricated CDs improve the clinical performance and PROMs compared with conventionally fabricated CDs. MATERIAL AND METHODS: This systematic review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses and was registered at the International Prospective Register of Systematic Reviews (CRD42023433909). This review aimed to address the question "Do digitally fabricated CDs improve clinical performance and PROMs compared with conventional CDs?" Two independent authors conducted electronic searches up to September 2023. Denture base retention and patient satisfaction were analyzed through the continuous outcome evaluated by mean difference and standard deviation, with 95% confidence intervals. The risk of bias in each study was assessed using the Risk of Bias In Non-randomized Studies of Interventions and the Risk of Bias based on the Cochrane risk of bias tool for randomized trials. The certainty of evidence was assessed using Grading of Recommendations, Assessment, Development and Evaluation. RESULTS: A total of 1505 articles were found during the search, and 16 were included in this review. The main outcomes were grouped into clinical performance (retention, adaptation or fit, clinician's denture quality assessment, masticatory efficiency, and occlusal force) and PROMs (patient satisfaction, oral health related quality of life, final choice, and willingness-to-pay). In terms of denture base retention, between conventional CDs and printed CDs analyzes, conventional CDs exhibited better retention (P=.02), but no significant difference was found between the conventional CDs and milled CDs (P=.20). In terms of patient satisfaction, no statistically significant difference was found between the manufacturing methods of digitally fabricated CDs (printed CD, P=.55; milled CD, P=.08). CONCLUSIONS: Digitally fabricated CDs showed similar or better clinical performance than conventional CDs, and different types of digital manufacturing processes for complete dentures did not influence PROMs.

Effectiveness of Elastic Therapeutic Tape in Reducing Edema, Pain and Trismus following Surgery for Facial Fractures: A Systematic Review and Meta-Analysis.

Facial fractures cause postoperative morbidity, including edema, pain, and trismus. Elastic therapeutic tapes are used for optimizing recovery. Background: The aim of the present systematic review and meta-analysis was to evaluate the effectiveness of elastic tape Kinesio taping (KT) in reducing postoperative morbidity in facial fractures surgeries. Methods: A systematic review was conducted in accordance with the PRISMA guidelines. Searches were conducted in the Cochrane, Medline, Scopus, Embase and Web of Science databases using a pre-established search strategy. Results: A total of 811 studies were retrieved after the duplicates were removed, and only randomized clinical trials were included. Eight trials, involving 319 participants, were deemed eligible. One study solely investigated the effect on edema, while the others analyzed at least two of the variables of interest. Results from two RCTs, where qualitative analysis was applicable, suggest a potential reduction in edema in the KT group compared to the control group on the second (RR -0.55, 95% CI -0.89 to -0.22; p = 0.01; I2 = 0%) and third postoperative days (RR -0.71, 95% CI -1.01 to -0.40; p < 0.00001; I2 = 0%). Conclusions: KT is effective in controlling postoperative edema following surgery for facial fractures. However, the effects on pain and trismus should be explored further in studies with standardized methods.

Muscle activity between dentate and edentulous patients rehabilitated with dental prostheses: A systematic review.

BACKGROUND: Adequate muscle activity is important for the success of oral rehabilitation: it maintains the integrity of the stomatognathic system and is responsible for chewing movements needed to break, crush and grind food. OBJECTIVE: To compare muscle activity using electromyography (EMG) while clenching or chewing soft and/or hard foods among individuals with natural dentition (ND) and edentulous patients rehabilitated with dental prostheses. METHODS: This review was conducted until March, 2023, and the research question was "Is the muscle activity of edentulous patients rehabilitated with dental prostheses similar to that of dentate individuals?" A search strategy was conducted in PubMed/MEDLINE, The Cochrane Library, Web of Science, Lilacs, Embase and manual journal searches. RESULTS: Ten studies were included in the analysis. Most of them reported that individuals with ND had significant higher muscle activity (clenching or chewing) than complete dentures (CD) users. However, no difference was observed between patients with full mouth implant-supported fixed dental prosthesis (ISFDP) and ND. Additionally, two studies compared patients with mandibular ISFDP with maxillary CD and individuals with ND and found no differences; however, one study concluded that patients with ISFDP with CD (maxillary or mandibular) had lower muscle activity than individuals with ND. Only one study reported a higher muscle activity in patients with full-mouth ISFDP than in individuals with ND. CONCLUSIONS: Bimaxillary CD users had lower muscle activity than individuals with ND. During rehabilitation, the muscle activity of patients with full-mouth ISFDP and mandibular ISFDP with maxillary CD is similar to individuals with ND.
