Antimicrobial Effect of a Single Dose of Amoxicillin on the Oral Microbiota
Amoxicillin is commonly used in oral surgery for antimicrobial prophylaxis against surgical-site infection and
bacteremia because of its effect on oral streptococci. The aim of this study was to determine whether amoxicillin reaches
the break-point concentrations in saliva and has any effect on the salivary microbiota, colonizing bacteria on mucosal
membranes and on the gingival crevice after a single dose of amoxicillin. A single dose given as prophylaxis to prevent a surgical-site infection results in a significant reducing effect on
the oral streptococcal microflora in the gingival crevice and may have an impact on bacteria spreading into tissues and the
bacteria of streptococci.
CAD/CAM Solutions for Minimally Invasive All-Ceramic Rehabilitation of Extended Erosive Lesions
Dental erosion is a global health problem that can lead to significant functional and esthetic impairments of the affected patients. Treatment of sever cases with augmented loss of the vertical dimension of occlusion (VDO) represents a challenge for both the dental team and the patient. CAD/CAM technology was used in the presented case to analyze the inter-occlusal space. The case report documents a practical, digital approach and discusses the advantages related to treatment time, ease of treatment, and predictability.
Updating Classifications of Ceramic Dental Materials
The indications for and composition of today’s dental ceramic materials serve as the basis
for determining the appropriate class of ceramics to use for a given case. By understanding
the classifications, composition, and characteristics of the latest all-ceramic materials,
which are presented in this article in order of most to least conservative, dentists and
laboratory technicians can best determine the ideal material for a given treatment.
Reconstruction of a Single-Tooth Traumatic Defect in the Anterior Maxilla Using the Khoury Bone Plate Graft
Trauma to teeth and the dentoalveolar process may result in a ridge defect that precludes straightforward implant
therapy of the patient. Typically bone and soft tissue augmentation of the area would first be needed to adequately
prepare the tissues for the implant and its restoration..Grafting of the site is substantially more difficult in cases where
the ridge also lacks adequate height, and techniques to recreate a bony envelope to apply guided bone regeneration
may be required. Moreover, defects in the anterior aesthetic zone that require both bone and soft tissue grafting and
a restoration that harmonizes the adjacent pink and white aesthetics may be an even more significant challenge to
the restorative team. Hereafter a case of trauma to an anterior maxillary tooth that saw destruction of the ridge is
presented, with the defect reconstructed to accommodate a functional and aesthetically pleasing implant supported
Retrospective Analysis of 26 Complete-Arch Implant-Supported Monolithic Zirconia Prostheses with Feldspathic Porcelain Veneering Limited to the Facial Surface
The purpose of this retrospective study was to evaluate the clinical performances of 26 implant-supported, complete-arch, monolithic zirconia restorations with facial feldspathic porcelain veneers for the rehabilitation of completely edentulous patients.
Eighteen patients were treated with a total of 26 complete-arch fixed prostheses. The mean follow-up time was 20.9 months. In total, 154 implants were placed supporting 309 retainers and pontics.
The results of this retrospective evaluation showed that monolithic zirconia restorations
with facial porcelain veneer provided satisfactory clinical performance and suggest that these
rehabilitations are a viable treatment option for completely edentulous patients.
