Evidence regarding the performance of digital dentures (DDs) fabricated using 3D printing is insufficient. This study aimed to evaluate patient satisfaction with conventional (CDs) and DDs printing.This randomized controlled trial was conducted between November 2017 May 2020. In CD-DD group, CDs were before DDs, while protocol reversed in DD-CD group. The primary outcome satisfaction, quantified a 100-mm visual analog scale, which assessed chewing efficiency, pain, stability, retention,...
Background This study characterized the changes in quality and quantity of saliva, salivary metabolomic profile, to understand effects masticatory stimulation. Methods Stimulated unstimulated saliva samples were collected from 55 subjects hydrophilic metabolites comprehensively quantified using capillary electrophoresis-time-of-flight mass spectrometry. Results In total, 137 identified quantified. The concentrations 44 stimulated significantly higher than those saliva. Pathway analysis...
This study examines the potential of computer-aided design (CAD) systems equipped with artificial intelligence (AI) in reducing workload dental technicians. We aimed to compare accuracy and time crowns designed using conventional CAD those AI-equipped CAD. Abutment tooth models a maxillary right second premolar (FDI classification #15) left first molar #26) were mounted on model form master model. Stereolithography data acquired an intraoral scanner, five technicians one crown each for #15...
Many reports show that denture adhesives improve the retention and stability of dentures. However, few randomized controlled trials have examined effects adhesives.This 10-center trial with parallel groups involving 200 edentulous patients wearing complete dentures aimed to evaluate short-term use cream powder adhesives.Patients were allocated into 2 cream- powder-type adhesive 1 control group. Intervention treated (1 each), group received saline solution. Adhesive or was applied...
We investigated whether surface roughness and control of electric charge a hydroxyapatite (HA)/titanium oxide (TiO2) hybrid coating could enhance biological responses associated with bone formation. After acid etching, titanium was modified HA TiO2 by the dual sputtering deposition technique using radiofrequency sputtering. These surfaces were analyzed for intensity. Rat marrow-derived osteoblast-like cells cultured on HA/TiO2 different charges. The attachment spreading behavior these...
Abstract Background Implant treatment using guided surgery is becoming widespread in clinical dental practice. Furthermore, the development of digital technology has enabled use intraoral scanners (IOSs) to fabricate surgical guide plates. The objective this study was compare accuracy silicone impression method with a three-dimensional (3D) scanner and IOS for one side mandibular free end. In addition, we compared tooth-supported vs tooth/mucosa-supported Results plate new instead obtaining...
Abstract Background The use of intraoral scanners (IOS) has facilitated the digital workflows for fabrication implant-supported prostheses not only single missing teeth, but also multiple teeth. However, clinical application IOS and computer-aided design/manufacturing (CAD/CAM) in prosthodontics remains unclear. This study aimed to compare accuracy silicone impressions single-tooth implants bounded edentulous spaces two-unit three-unit fixed dental free-end spaces. Methods enrolled 30...
This study aimed to determine the effects of denture adhesives on retention and occlusal force in complete wearers a multicenter, randomized, parallel-group controlled trial.Two hundred edentulous patients wearing dentures were allocated three groups: powder-type adhesive, cream-type control (saline solution). Denture saline solution applied for 4 days. The retentive measured using transducer meter at baseline after days intervention. In addition between-group comparisons, subgroup analyses...
The objective of this study was to investigate morphologically the progression periimplantitis around an ultraviolet (UV)-light-irradiated implant in dogs.Pure titanium implants (3.3 mm diameter and 8 long) were placed into dog jawbone bilaterally. Implants on one side irradiated with UV light for 15 minutes using a photodevice immediately before placement (UV group), whereas those other not (non-UV group). Osseointegration confirmed 90 days after by radiography. Experimental induced...
Purpose To investigate the difference in improvement of oral health-related quality life (OHR-QoL) depending on and denture conditions a complete wearer when using cream or powder type adhesive 10-center parallel randomized clinical trial.
Multi-directional forging (MDFing) of titanium drastically improved its mechanical properties due to the evolution an ultrafine-grained structure. Forging strain was repeatedly applied while changing axis during MDFing. Of note is decreased elastic modulus MDFed (MDF-Ti) as compared conventional coarse-grained pure Ti (Ti). In present study, we evaluated bone’s response toward surface-treated MDF-Ti after implantation into extraction sockets rat maxillary molars. As surface treatments, acid...
The purpose of this study is to investigate the effects denture adhesives on masticatory performance via a 10-center, parallel, randomized, controlled trial complete wearers in Japan.
Denture adhesives, characterized as medical products in 1935 by the American Dental Association, have been considered useful adjuncts for improving denture retention and stability. However, many dentists Japan are hesitant to acknowledge adhesives daily practice because of stereotype that dentures should be inherently stable, without aid adhesives. The aim this study is verify efficacy establish guidelines Japanese users. null hypothesis application including cream powder types, or a control...
Early detection of oral candidiasis is essential. However, most currently available methods are time-consuming and useful only for screening patients. Previous studies on the relationship between saliva have focused volume not its components. Therefore, to clarify effects salivary metabolites, components was investigated by comparing metabolites patients those previously diagnosed with candidiasis. Forty-five participants visiting our university hospital were included classified into two...
As our society ages, the number of people living with dementia also steadily increases. Some work has focused on masticatory behaviour as a form daily health care that could help prevent cognitive impairment and dementia. However, it is not yet clear how influences various functions. Therefore, purpose this study was to examine effect decline generalized attention, an important function.Participants were 35 healthy, dentulous individuals without stomatognathic abnormalities (24 men, 11...
The major causes of oral candidiasis include decreased salivary flow rate and the use ill-fitting dentures. However, relationships among prosthetic treatment, saliva, Candida albicans have not been elucidated. This study aimed to examine effects treatment changes in saliva (mainly rate) on symptoms. Participants requiring underwent testing for C. albicans, rate, intraoral symptoms, bite force at initial visit four months after evaluate pretreatment post-treatment changes. dentures, symptoms...
Titanium are often used as dental materials, pure titanium present low strength and alloy is reported poor biocompatibility, respectively. To overcome the problem, we fabricated high-strength multi-directional forged (MDF) with improved mechanical properties without changing chemical composition evaluated its applicability in prosthetic crowns. Cutting tests: average absolute value of difference before after cutting was calculated uncut amount. Surface evaluations: MDF titanium, Ti-6Al-4V...
Aim: In recent years, the number of patients complaining symptoms oral discomfort such as dry mouth, tongue pain, and burning sensation mouth has been increasing. This study aimed to determine whether denture treatment improved accompanying sticky sensations. Methods: Forty-eight partial and/or complete wearers were recruited from non-xerogenic with normal salivary flow after obtaining informed consent. Measurement outcomes were: 1) subjective evaluated by self-administered questionnaire,...
