Abstract Purpose To compare the flexural strength of different computer‐aided design/computer‐aided manufacturing (CAD/CAM) poly(methyl methacrylate)‐based (PMMA) polymers and conventional interim resin materials after thermocycling. Materials Methods Rectangular‐shaped specimens (n = 15, for each material) (25 × 2 mm 3 ) were fabricated from CAD/CAM PMMA‐based (Telio CAD [T]; M‐PM‐Disc [M]; Polident–PMMA [P]), 1 bis‐acrylate composite (Protemp 4 [PT]), PMMA (ArtConcept Artegral Dentine [C])...

Abstract Purpose To compare the amount of adherent Candida albicans to different CAD/CAM poly(methyl methacrylate) (PMMA)‐based polymers and conventional heat‐polymerized PMMA after long‐term thermal cycling. Materials Methods The specimens were subjected 10,000 cycles (5‐55°C) divided into two groups, uncoated pellicle‐coated. Surface roughness contact angles measured. surface morphology was observed with scanning electron microscopy (SEM). An adhesion test performed by incubating disk in...

To investigate the reliability and accuracy of cone beam CT (CBCT) images obtained at different fields view in detecting quantifying simulated buccal marginal alveolar peri-implant defects.Simulated defects were prepared 69 implants inserted into cadaver mandibles. CBCT three acquired: 40 × 40, 60 100 mm. The presence or absence was assessed on sets using a five-point scale by observers. Observers also measured depth, width volume images, which compared with physical measurements. kappa...

Since the introduction of cone-beam computed tomography (CBCT), several novel systems with different technical specifications and settings have become commercially available. Therefore, it is essential to evaluate CBCT for differences in subjective quality images obtained various dental procedures. We evaluated image cross-sectional scans from systems. Images three cadaver mandibles were four units: 1) Veraviewepocs 3D 40 × mm field view (FOV) (voxel size: 0.125 mm), 2) Iluma, low-resolution...

Abstract – Aim: To determine the effects of digital image enhancement on observer ability to detect experimentally induced vertical root fractures (VRF). Material and methods: A total 64 extracted human mandibular premolar teeth were used in this study. In 32 teeth, VRFs created bucco‐lingual planes by gently tapping with screw‐type root‐canal pins. The remaining intact served as a control group. Digital images obtained using charge coupled device sensor. Three observers separately examined...

Objectives: To compare limited cone beam computerized tomography (CBCT) units with different field of views (FOVs) and voxel sizes in detecting artificially created horizontal root fracture (HRF) extracted human teeth. Methods: Artificial HRF was the plane 40 Another intact teeth served as a control group. 80 were placed respective maxillary anterior sockets dry skull groups. Six image sets obtained: (1) Accuitomo 170, × mm FOV (0.080 mm3); (2) 60 (0.125 (3) Kodak 9000, 50 37 (0.076 (4)...

The majority of maxillary defects can be rehabilitated with conventional simple obturator prosthesis. However, inadequate retention, stability and support may associated the use an obturator. Precision attachments have been used to retain obturators for some time. precision in a dentate maxillectomy patient yield significant functional improvement while maintaining obturator's aesthetic advantages. This clinical report describes prosthetic rehabilitation two retained using extracoronal...

The aim of the present study was to assess intraoral images and two cone beam computed tomography (CBCT) systems for detection artificial buccal recurrent caries under restorations. Class V cavities were made composite (30 teeth) amalgam teeth). Full restorations with thermoplastic polymer nickel-chromium metal crown constructed. In 60 teeth, simulated; other teeth served as controls. Intraoral film, digital, Veraviewepocs 3D, Kodak 9000 scored twice. κ Coefficients calculated Az values...

This study aimed to investigate the effects of 16% carbamide peroxide (CP) on relative translucency parameter (RTP) and color stability thermally aged CAD-CAM glass-ceramics with glazing or polishing. Three different blocks-feldspathic (VM), lithium disilicate (IPS), zirconia-reinforced silicate ceramic (VS)-were used in this study. The specimens were divided into two groups (n=10) according surface treatments (glazing polishing). Bleaching treatment CP was applied specimens. A...

The present study compared the use of cone beam computerized tomography (CBCT) images and intra-oral radiographs in placement final implant drills terms nerve damage to cadaver mandibles. Twelve hemimandibles obtained from 6 cadavers were used. Right imaged using peri-apical radiography left CBCT, used treatment planning for (22 each modality, a total 44 drills). Specimens dissected, distances between apex drill inferior alveolar neurovascular bundle incisive measured digital calliper....

The aim of the present study was to measure accuracy cone-beam computerized tomography (CBCT)- aided StentCad Beyond surgical guidance system and compare bone-supported tooth/bone-supported by using this in dental implant placement ex vivo. Five cadaver mandibles were scanned an Iluma CBCT scanner. After scanning, DICOM slices transferred simulation software, which used for preoperative planning. Using system, 9 drills inserted a 11 system. Mandibles again these data software. Pre-...

This case study reports on the prosthetic rehabilitation of a patient with an unrepaired bilateral cleft lip and palate using osseointegrated implants, extracoronal resilient attachments, combination metal-ceramic cement-retained fixed partial restorations, removable prosthesis.
