Implant-supported, bar-retained maxillary overdenture and Mandibular Implant-supported, metal- acrylic resin, screw-retained, fixed complete denture on an edentulous patient: Case Report.

Most edentulous patients prefer fixed restoration or detachable prostheses over conventional complete dentures. The case report aims to address and discuss the clinical and laboratory steps of implant-supported, bar-retained maxillary overdenture and mandibular implant-supported, metal-acrylic resin, screw-retained, fixed complete denture. Impression techniques and laboratory steps are discussed and demonstrated to minimize the post-fabrication or insertion complication. It lets you achieve the passive fit of the prosthesis that maintains the osseointegration by reducing stress on implants and the surrounding bone.

Stroke and high-risk TIA outcomes with reduction of treatment duration when treatment initiated in emergency rooms (SHORTER-study).

BACKGROUND: Following transient ischemic attack (TIA) and minor stroke, the risk of recurrent stroke can be significantly reduced with short-duration dual antiplatelet therapy (DAPT). We wish to investigate whether 10 days of DAPT is as effective as 21 days' treatment. STUDY DESIGN: This is an open-label, randomized, parallel-group study comparing whether 10 days of DAPT treatment (ASA + clopidogrel) is non-inferior to 21 days of DAPT in patients with acute ischemic stroke (AIS) or high-risk TIA. In both groups, DAPT is started within 24 hours of symptom onset. This study is being conducted in approximately 15 study sites in the Kingdom of Saudi Arabia. The planned sample size is 1932. OUTCOMES: Non-inferiority of 10 days compared to 21 days of DAPT in the prevention of the composite endpoint of stroke and death at 90 days in AIS/TIA patients. The primary safety outcome is major intra-cranial and systemic hemorrhage. STUDY PERIOD: Enrolment started in the second quarter of 2023, and the completion of the study is expected in the fourth quarter of 2025. DISCUSSION: The trial is expected to show that 10 days of DAPT is non-inferior for the prevention of early recurrence of vascular events in patients with high-risk TIAs and minor strokes.

Association between gastric reflux, obesity and erosive tooth wear among psychiatric patients.

ABSTRACT: The prevalence of erosive tooth wear and obesity are high in psychiatric patients and soft drink consumption is a common risk factor associated with both diseases. This study aimed to assess the association between soft drink consumption, gastric reflux, erosive tooth wear, and obesity among resident patients at the Psychiatric Hospital, Taif, Saudi Arabia.This descriptive, cross-sectional study included 223 adult psychiatric inpatients (126 male, 97 female) with a mean age of 42.3 years (± 2.2). Dental erosion detection was performed according to World Health Organization criteria. The medical evaluation included assessment of the body mass index (BMI). With appropriate sample weighting, relationships between erosive tooth wear, gastric reflux, and obesity were assessed using multivariable logistic regression.Ninety eight patients (43.9%) presented with erosive tooth wear. The mean BMI for the entire study population was 27.7 ±â€Š6.3 kg/m2. Regression analysis showed a strong association between erosive tooth wear and chronic vomiting or bulimia (adjusted odds ratio = 2.11; 95% confidence interval [CI] = 1.98-5.07, P < .001), gastric reflux (adjusted odds ratio = 2.13; 95% CI = 1.34-6.23, P < .001), consumption of soft drinks (adjusted odds ratio = 2.14; 95% CI = 1.03-6.08, P < .001), and schizophrenia and delusional disorders (adjusted odds ratio = 2.07; 95% CI = 1.98-5.08, P < .001).This study demonstrates a significant association between erosive tooth wear prevalence and chronic vomiting or bulimia, consumption of soft drinks, and gastric reflux among resident patients at psychiatric hospital.

Effect of time period on biaxial strength for different Y-TZP veneering porcelains.

OBJECTIVE: To assess the influence of time period on strength for different conventional Y-TZP porcelains. MATERIALS AND METHODS: Four types of porcelain were used. Porcelain powders were pressed in a steel die and fired in a furnace as recommended by the manufacturer. The blocks were sectioned into 2 mm-thick discs. Seventy specimens were fabricated from each type of porcelain. Of six jars, three contained 40 mL of dH2 O and three were dry. Ten specimens were placed in each jar and stored in an incubator at 37°C. A biaxial flexural strength test was performed for all specimens at the baseline and each succeeding year for all groups, for 3 years, using an Instron with a crosshead speed of 0.5 mm/min. RESULTS: The data were analyzed by ANOVA and Tukey at α = .05. At the baseline, the biaxial flexural strength of VitaVM9 was significantly higher than that of NobelRondo; however, there were no significant differences among Vita VM9 and Noritake CZR or NobelRondo, Lava Ceram, and Noritake CZR. There were significant reductions in the biaxial flexural strengths of all porcelains. CONCLUSIONS: After 3 years, all porcelain groups showed a significant decrease in biaxial flexural strength. The medium used is found to have no significant effects on the mean biaxial flexural strength. CLINICAL SIGNIFICANCE: Certain commercially available Y-TZP porcelains are susceptible to decrease in strength over time, which might impact the integrity of veneered zirconia restorations. This reduction in strength is among the most common reasons for the failure of veneered zirconia as reported in several studies.

Effect of Multilayering Incremental Technique on the Microleakage of High-viscosity Bulk-fill Composite Restorations in Endodontically Treated Teeth.

AIM: The aim of this study is to evaluate the effect of multilayering incremental technique on the microleakage of high-viscosity bulk-fill composite restorations in endodontically treated teeth. MATERIALS AND METHODS: A total of 60 human mandibular premolar teeth were divided into four groups after standardized access preparation with a protaper technique followed by single-cone obturation to receive the following restorations for the access preparations. Group I (n = 20): bulk-fill composite (Filtek™ Bulk fill) using a bulk technique, group II (n = 20): bulk-fill composite (Filtek™ Bulk fill) using an incremental layering technique, group III (negative control) (n = 10): gutta-percha was kept intact at the access orifice and covered with a nail polish, and group IV (positive control) (n = 10): gutta-percha was kept intact at the orifice. The samples were thermocycled at 5°C and 55°C for 500 cycles followed by dye penetration with 2% methylene blue and then the scoring was done under a stereomicroscope at 10× magnification. The data so obtained were compared for microleakage using a Chi-square test. There was a significant difference among all the groups except groups II and III. RESULTS: Bulk-fill composites used with an incremental layering technique sealed significantly better than the other groups followed by bulk-fill composite in the bulk technique. CONCLUSION: Within the limitations of the present study, it can be concluded that the incremental layering technique with bulk-fill composites significantly decreases microleakage in the restored access preparations of endodontically treated teeth.
