Filter by:This study will be conducted to: Evaluate and compare the clinical success, periodontal changes, and wear of antagonist teeth for three types of prefabricated crowns in primary molars: BioFlx crowns, Zirconia crowns, and Stainless Steel crowns.
To compare biological, technical, radiographic, and patient-reported outcomes of two types of monolithic zirconia crowns screw-retained to implant. To assess whether the new form of multilayered zirconia crowns will show similar survival and success rate to conventional monolithic Zirconia screw-retained to implants in molar and premolar regions. First Null Hypothesis: Multilayered monolithic zirconia crowns would have similar survival, success rate compared to conventional monolithic zirconia implant supported crowns. Second Null hypothesis: There would be no difference in clinical and patients related outcomes between multilayered and conventional monolithic zirconia implant supported crowns.
Title: Evaluation of the impact on general functionality of the application of an immediate prosthetic functionalization protocol, in patients with deficient removable prostheses, compared with the conventional treatment that is delivered at the secondary level of the health system, to people over 70 years of age. Introduction: Sarcopenia and malnutrition are closely involved in frailty. To prevent them it is important to assess oral function. "Oral fragility" manifests with specific signs or symptoms, among which are loss of occlusion due to tooth loss and chewing difficulty. To recover from it, it is important to restore function by placing a dental prosthesis in the event of tooth loss. In Chile, a large percentage of patients who are referred to secondary care to perform new prosthetic treatment, lives in conditions of less oral functionality and enters waiting lists that can take years, with a silent impact on general functionality. Falls are a public health problem with a significant economic cost, being the second cause of death worldwide. One of the causes is sarcopenia and it has been studied that the decrease in the number of teeth and the occlusal posterior support region may be risk factors for decreased gait speed, an objective measurement of fall risk. It has been studied that the decrease in the number of teeth causes a reduction in: total muscle mass, walking speed and lower quality of life. Hypothesis: The recovery of immediate functionality in deficient prostheses in patients 70 years of age and older will have a positive and rapid impact on general functionality and on their assessment of oral health related quality of life. General objective: To evaluate the impact on general functionality of the application of an immediate prosthetic functionalization protocol in patients with deficient removable prostheses, compared with conventional treatment, at the secondary level of the health system, in patients over 70 years of age. Methodology: randomized, double-blind clinical trial with two groups of 62 patients each: experimental and control. The intervention will consist of recovering prosthetic function in one session, before conventional rehabilitation vs. the control group that will receive conventional rehabilitation. Measurements will include manual grip strength measurements, made with a Jamar dynamometer, timed up and go test, before and after prosthetic treatments and quality of life related to oral health through Ohip 7sp. Descriptive statistics will be applied, through the registration of frequency and contingency tables. To compare hand grip strength, the Pearson's Correlation will be used; for risk of pre and post fall, the t-test will be applied for 2 related samples; for quality of life before and after intervention, Chi2 will be used; changes in grip strength, fall risk and quality of life, between the different groups according to the Eichner index, one-way ANOVA will be applied, for related samples. Results: A short-term improvement is expected in patients whose functionality will be recovered, which, being a simple technique of competence of the general dentist, could be applied in primary care, without loss of valuable time before attention is achieved, at the secondary level for rehabilitation with new prostheses.
This is in vivo study aimed to evaluate the color stability of the newly introduced resin ceramic matrix (cerasmart )& (vita-enamic ) after a one year
A multicenter prospective observational study aims to illustrate the clinical outcome of dental implants "Kontact MB" and the effects of its Mono Block design on the peri implant bone tissue recession and soft tissue conservation. All the enrolled patients will be eligible for one or multiple implant-supported fixed restoration(s) according to the routine clinical practice and the manufacturer's instruction for use.
Objective: To evaluate the immediate clinical performance using FDI criteria in occlusal and proximal lesions restored with dual polymerization bulkfill composite resin. Materials and methods: Experimental, clinical, controlled, randomized, double-blind study. For the evaluation of Fill-up! (FU) will be clinically compared to the control groups of a conventional Tetric N-Ceram (TB) RBK and Filtek z350 (z350) conventional composite resin. The adhesive process will be carried out under absolute isolation, of selective etching of 37% orthophosphoric acid enamel before applying the respective adhesive according to the trademark of the composite resins. The evaluation will be to 30 days, 6, 12, 18 and 24 months using the modified FDI criteria of postoperative sensitivity, marginal staining, color, marginal adaptation and anatomy, being 1: Excellent, 2: Good, 3: Fair, 4: unsatisfactory and 5: unacceptable. The non-parametric Kruskal Wallis test and Friedman (95% significance) used to compare the criteria.
One of the main difficulties encountered in esthetic dentistry is the complexity associated with shade matching and layering technique to achieve optimal esthetic outcomes. To ensure an esthetic outcome, an imperceptible match of the color of the restorative material to that of the tooth is of utmost importance. Recently, a new shade matching composite that utilizes "smart chromatic technology", developed by Tokuyama was claimed to be able to capture the structural color of its surroundings teeth. Our main objective is to assess the blending capacity of OMNICHROMA composite material in anterior restorations of patients attending the Jordan University Hospital. Both visual and instrumental measurements will be performed and the differences between the shade of the composite resin and the tooth structure will be measured. In addition, multi chroma composite restorations will be placed for the purpose of comparison (control).
A multicenter prospective observational study in which aim is to illustrate the clinical outcome of dental implants "Kontact N"; and the effects of its nanostructured surface on the osseointegration and secondary stability without increasing the rate of peri-implantitis. All the enrolled patients will be eligible for one or multiple implant-supported fixed restoration(s) according to the routine clinical practice and the manufacturer's instruction for use.
The primary objective of this study is to evaluate long-term clinical performance of a glass hybrid restorative system (glass-ionomer) vs. composite resin material over a period of five years. The secondary objective is to evaluate the suitability of intraoral impressions for the assessment of wear of teeth and restorative materials over five years. For that purpose the replica method and scanning 3-D laser equipment and matching software will be used. The first null hypothesis is that there would be no difference in clinical performance between restorative materials after five years. The second null hypothesis is that wear between the restorative materials will be the same after five years. This is a multicentre, controlled clinical study conducted in Croatia, Italy, Turkey and Serbia. Eligible participants are all adults aged 18 or over with indication of restorative treatment on vital teeth in posterior molar region, limited to two surface in a healthy subjects. Exclusion criteria are presence of full dentures or crowns and bridges in occlusal contact with teeth indicated for restorative treatment, severe bruxing and unstable physiological or medical health, pregnancy and lactation, radiation therapy or using drugs. Each patient is receiving two restorative treatment (GIC-EQUIA Forte and composite resin material Tetric EvoCeram) each of which will be localized on molar teeth on either side of the mouth. Two independent examiners will evaluate the restorations at each site one week after placement and at one, two, three, four and five years according to the FDI criteria. After, three and five years recall, impressions of both restorations is taken and the casts is analysed by a 3D laser scanner.
The main objective of this entire research project is to develop a miniature atmospheric cold plasma brush (m-ACPB) for dental clinical applications. The objective of the clinical trial portion of the study is to compare the longevity and durability of dental composite restorations created using the plasma brush, to that of the standard care in dentistry for treating dental cavities, and effects on caries prevention.
