Filter by:Purpose: The present study was aimed to evaluate the bone height changes around abutments with two different framework materials for extracoronal attachment mandibular bilateral distally extension removable partial denture (RPD) and compare patient satisfaction associated with its use. Materials and methods: Ten partially edentulous patients (long span kennedy class I) were selected, for all patients splinting of remaining abutment were done by porcelain fused to metal bridges, after cementation the RPD frameworks were digitally designed by CAD software and printed into 3-D resin pattern after intra-oral try in of these patterns, the patients were divided into two equalized groups, the patients in first group received extracoronal attachment (RPD)with from milled PEEK (Juvora) framework. While patients in second group received extracoronal attachment (RPD) with conventional metal framework by lost wax technique. Digital radiography was used for bone height assessment of distal abutment at time of prosthesis insertion, 6 and 12 months later. Patient satisfaction was measured using VAS scale.
Objectives: The objective of this study was to assess prospectively the effectiveness of ultrasonic denture hygiene interventions in improving denture cleanliness among community-dwelling elders. Methods: A randomized clinical trial was conducted among community-dwelling elders, in which a total of 66 subjects who received upper metal framework removable partial dentures in the past five years were recruited randomly from a computerized database. They were randomly allocated into three denture hygiene intervention groups: group 1 (mechanical cleaning with a toothbrush and ultrasonic cleaning with cetylpyridinium chloride mouthrinse), group 2 (mechanical cleaning with a toothbrush and ultrasonic cleaning with distilled water) and control (mechanical cleaning with a toothbrush only). Denture cleanliness was assessed at baseline and one month review using: i) Denture Cleanliness Index (DCI) scores; ii) plaque coverage percentage; and (iii) microbiological tests. Results: There were significantly greater reductions in mean DCI scores and mean percentage of plaque coverage area in group 1 and group 2 compared to the control group for both CoCr and acrylic fitting surfaces (p<0.001). Group 1 had significant reductions in the viable counts of bacteria (CoCr and acrylic) and yeast (CoCr only) (p<0.05), while only significant reductions in bacterial viable counts (CoCr and acrylic) (p<0.05) were documented in Group 2. No significant differences were detected between groups 1 and 2 with regards to all clinical and microbiological outcomes. When comparing these parameters for CoCr and acrylic surfaces, no significant differences were observed following the intervention period. Conclusions: The ultrasonic cleaner was significantly more effective than the control in the reduction of biofilm coverage on metal framework removable partial dentures during the one month intervention period. The adjunctive use of cetylpyridinium chloride with ultrasonic cleaning did not yield improved outcomes compared to water.
