Abstract Purpose While the incorporation of antimicrobial agents into soft denture liners has been suggested as a reliable alternative treatment for stomatitis, it may affect liner's properties. The effect addition stomatitis on surface roughness and Shore A hardness lining materials was evaluated. Materials Methods test groups comprised specimens (36 × 7 6 mm 3 ) (Softone Trusoft) without (control) or with drugs (nystatin, miconazole, ketoconazole, chlorhexidine diacetate, itraconazole)....

Microwave energy has been used as an alternative method for disinfection and sterilization of dental prostheses. This study evaluated the influence microwave treatment on dimensional accuracy along posterior palatal border maxillary acrylic resin denture bases processed by water-bath curing. Thirty (3-mm-thick) were made cast models with Clássico using routine technique. After polymerization cooling, sets deflasked stored in water 30 days. Thereafter, specimens assigned to 3 groups (n=10),...

To evaluate the effectiveness of three types abutments in maintenance screw joint preload before and after cyclic loading as well to observe possible microdamage structure components using a scanning electron microscope (SEM).Forty-five external-hex implants were embedded epoxy resin, received their respective abutments, randomly divided into experimental groups (n = 15): (1) machined titanium (Ti) abutments; (2) pre-machined gold (Au) (3) zirconia (ZrO(2)) abutments. The abutment screws...

Purpose : To evaluate the effects of disinfection treatments with chemical solutions (2% glutaraldehyde, 5% sodium hypochlorite, and chlorhexidine) microwave energy on hardness four long‐term soft denture liners. Materials Methods: Forty rectangular specimens lining materials (Molloplast‐B, Ufi Gel P, Eversoft, Mucopren soft) were made for each material. Ten samples material immersed in different disinfectant 10 minutes or placed a oven 3 at 500 W. The values obtained Shore A durometer,...

This study evaluated the in vitro adherence of pathogenic micro-organisms, Candida albicans, Staphylococcus aureus and Pseudomonas aeruginosa, to soft lining materials their inhibitory effect on these micro-organisms.To measure adherence, specimens Molloplast B Ufi Gel P were inoculated [10(7 )colony-forming units per millimetre (cfu/ml)] with TSB media containing micro-organisms. To determine number micro-organisms 10(-2)-10(-5) dilutions, 25 microl suspension transferred plates selective...

Denture fractures are common in daily practice, causing inconvenience to the patient and dentists. repairs should have adequate strength, dimensional stability color match, be easily quickly performed as well relatively inexpensive. OBJECTIVE: The aim of this study was evaluate flexural strength acrylic resin processed by different methods: warm water-bath, microwave energy, chemical polymerization. MATERIAL AND METHODS: Sixty rectangular specimens (31x10x2.5 mm) were made with water-bath...

There is a lack of clinical evidence on mandibular overdentures (MOD) supported by single implant. Objective: To compare patient satisfaction and masticatory performance in MOD one versus two implants two-group parallel randomized trial. Material Methods: Twenty-one patients wearing new maxillary complete dentures (CDs) were randomly divided to receive (GI, n = 11) or (GII, 10) the arch. Four months after implant placement, o-ring abutments installed implants, matrix attachments placed lower...

doi: 10.1111/j.1741‐2358.2011.00462.x Antimicrobial activity of disinfectant agents incorporated into type IV dental stone Purpose: This study evaluated the antimicrobial two agents, 2% chlorhexidine digluconate solution (CHX) and 98% hydrochloride powder (HYD), at time mixing. Material methods: Agar diffusion test was used for following microorganisms: Escherichia coli, Staphylococcus aureus, Bacillus subtilis Candida albicans . The specimens were grouped in: (1) mixed with sterile...

The assessment and reestablishment of the occlusal vertical dimension (OVD) are considered important factors in treatment complete denture wearers. long-time use a can result jaw displacement due to abrasion artificial teeth residual ridge resorption, causing esthetic complications. Most patients with old dentures incorrect OVD accept new dentures, even if they were used their dentures. present clinical report describes method gradual using diagnostic acrylic splint on before manufacture...

The literature is unclear about bite force (BF) and handgrip (HF) in a specific group of different ages dentate conditions, or even predictive model for each group, using BF HF as factors.To establish the correlation between female participants with distinct conditions; also create function HF.Participants were divided into three groups (GI: young natural women, n = 65; GII: adult 67; GIII: edentulous women users bimaxillary complete dentures, 67) subjected to an measurement test digital...

The literature is unclear about how the different attachment systems for overdentures impact maximum bite force, masticatory efficiency and this in oral health self-perception patients.

To evaluate the effectiveness of abutment screws coated with liquid Vaseline on screw-joint stability yttria-stabilized tetragonal zirconia (Y-TZP) systems.Forty Y-TZP prefabricated abutments, 20 Neodent and Bionnovation, were tightened to Ncm their respective external hexagon implants, divided into four groups (n = 10) according screws: or uncoated. The removal torque (RT) value screw was measured before after loading. A cyclic loading (0.5 × 106 cycles; 15 Hz) between 11 211 N applied....

Abstract Despite requiring dental crown preparation and possible root canal treatment, besides the difficulty of clinical laboratory repairs, financial burden, association between fixed (FPD) removable partial dentures (RPD) by means attachments is an important alternative for oral rehabilitation, particularly when use implants FPDs limited or not indicated. Among advantages attachment‐retained RPDs are improvements in esthetics biomechanics, as well correction buccal arrangement anterior...

During oral rehabilitation of an edentulous patient with implant-supported prosthesis, mandibular flexure must be considered important biomechanical factor when planning the metal framework design, especially if implants are installed posterior to interforaminal region. When mandible is restored a fixed prosthesis connected by full-arch framework, may cause needless stress in overall restorative system and lead screw loosening, poor fit loss implant, patient's discomfort due deformation...

Abstract Introduction Screw-retained restorations have a screw access hole (SAH) sealed with resin composite aiming at safe-guarding the aesthetic features of ceramic veneer. The loss or wear applied in sealing SAH is among most common complications implant prosthodontics, as fracture Objective Evaluate influence sealant materials on resistance screwed implants. Material and method samples were produced from UCLA abutments metallic NiCr alloy subsequent application ceramic. After...
