Abstract Objective Microorganisms harboring the oral cavity, mainly those related to periodontal diseases, are most potential etiologic factor of failure in long‐term implant treatment. The material used for abutment components may influence adhesion and colonization microbial species. aim this vivo investigation was evaluate biofilm formation on machined ( MPT ) or cast titanium CPT zirconia abutments (Zc). Methods Six healthy subjects were enrolled randomized crossover clinical...
A mandibular implant-retained overdenture is considered a first-choice treatment for edentulism. However, some aspects limit the use of standard implants—for example, width edentulous ridges, chronic diseases, fear, or costs. This randomized trial compared overdentures retained by 2 4 mini-implants with implants, considering oral health–related quality life (OHRQoL), patient satisfaction, and complications such as lost implant. In sum, 120 men women (mean age, 59.5 ± 8.5 y) randomly received...
Abstract: Dental implants provide patients with restorative options for the edentulous maxilla. Both fixed and removable prostheses can be attached to maxilla, but efficacy of different designs has not been determined. In this two‐session within‐subject crossover trial we compared maxillary implant retained overdentures opposed by mandibular implant‐supported overdentures. Sixteen patients, who had previously received implants, entered study four six implants. After dropouts as a consequence...
Although maxillary implant overdentures are used in oral rehabilitation, different designs have not been compared previously clinical trials. This crossover trial was designed to measure differences patient satisfaction with long‐bar and without palatal coverage opposed by a fixed mandibular implant‐supported prosthesis. Data were also gathered on new conventional dentures prostheses. Sixteen participants selected from population wearing dentures. Fifteen received upper lower (1 drop‐out)....
The aim of this study was to validate an original portable device measure attachment retention implant overdentures both in the lab and clinical settings. built with a digital force measurement gauge (Imada) secured vertical wheel stand associated customized support hold position denture adjustable angulations. Sixteen matrix patrix cylindrical stud attachments (Locator) were randomly assigned as vitro test specimens. Attachment abutments analogue hung or load cell traction machine used gold...
Summary This study assessed the effect of simulated mastication on retention two stud attachment systems for 2-implants overdentures. Sixteen specimens, each simulating an edentulous ridge with implants and overdenture were divided into groups, according to system: Group I (Nobel Biocare ball-socket attachments) II (Locator attachments). Retention forces measured before after 400 000 masticatory loads in a customised device. Data compared by two-way anova followed Bonferroni test (α = 0·05)....
Bacterial penetration along the implant-abutment interface as a consequence of abutment screw loosening has been reported in number recent studies. The aim this vitro study was to investigate influence repeated tightening on leakage Streptococcus mutans between implants and pre-machined abutments.Twenty abutments with plastic sleeve were used. screws tightened 32 N cm group 1 (n=10 - control) cm, loosened re-tightened same torque twice 2 (n=10). assemblies completely immersed 5 ml Tryptic...
Summary The retention of removable dentures by mini‐implants is a relatively recent treatment modality and may lead to minimal post‐operative trauma. This study compared pain discomfort following the insertion (two or four) two standard‐size implants for mandibular overdentures. One hundred twenty edentulous participants (mean age 59·5 ± 8·5 years) were randomly allocated into three groups according received treatment: ( GI ) four mini‐implants, GII GIII standard implants. Seven days after...
To evaluate the checkerboard DNA-DNA hybridization method for detection and quantitation of bacteria from internal parts dental implants to compare bacterial leakage connected either cast or pre-machined abutments.Nine plastic abutments in a Ni-Cr alloy nine Co-Cr with sleeves were Branemark-compatible implants. A group was used as control. The inoculated 3 microl solution containing 10(8) cells/ml Streptococcus sobrinus. Bacterial samples immediately collected control while assemblies...
ABSTRACT Objectives Peri‐implantitis is mostly caused by a pathological biofilm that forms through complex processes, initiated the formation of salivary pellicle on implant surfaces. Understanding nature these pellicles and how to remove them important for preventing peri‐implant infections improving success dental implants. This study explores characteristics titanium surfaces assesses effectiveness different decontamination agents in eliminating related microbial contaminations. Materials...
The purpose of this study was to evaluate bacterial survival rate on toothbrushes after brushing and the efficacy their decontamination by spraying antimicrobial solutions. Thirty subjects were instructed spray solutions toothbrush bristles brushing. Each volunteer tested three sprays, one solution per week; sprays labeled 1 (cetylpyridinium chloride - CPC basic formulation), 2 (basic formulation only) 3 (control sterile tap water). At end each week, brushes collected sonicated in Letheen...
