Vertical or Shoulderless Preparations in Contemporary Prosthodontics

Description:
Tooth preparations without a defined finish line have been termed in several different ways, such as knife edge, feather edge, or shoulderless. With slight differences between each other, all this preparation types may be defined “vertical” as opposed to “horizontal” ones (shoulder, chamfers) and since the introduction of metal ceramic they have been almost abandoned, with limited exceptions (i.e.: periodontically involved abutments).

Vertical or Shoulderless Preparations in Contemporary Prosthodontics
Tooth preparations without a defined finish line have been termed in several different ways, such as knife edge, feather edge, or shoulderless. From a biological standpoint, preserving a maximum amount of sound tooth structure, as it is done in vertical preparations, might also offer a more conservative alternative to a horizontal margin design in other clinical conditions such as endodontically treated teeth, vital teeth in young individual, teeth affected by caries at the cervical third. Vertical margins on zirconia crowns have been tested in vitro and clinical reports have been published. A re-evaluation of possible advantages and shortcomings of vertical preparation design in contemporary prosthodontics will be presented in light of recently published literature.

Indications of In-Office Treatments: Topical Fluoride, Varnish, Foam and Gels Premium Member Content

Indications of In-Office Treatments: Topical Fluoride, Varnish, Foam and Gels
A study conducted in the 1990s, demonstrated a steady rate of decline of instances of coronal caries through the 1980s. This decline was attributed to an increase in oral health education regarding diet, oral hygiene and an increased awareness about the benefits of applying fluoride-containing topical treatments such as dental sealants varnishes, foams, or gels to the teeth of individuals of all ages in moderate-to-high risk groups for caries. This presentation reviews the history, efficacy, and indications. You will learn the history of all varnishes, differences in fluoride foams and gels as well as which fluorides work best for different patients and practices.

Surgical Management of the Full Arch Patient; Do's & Don'ts
The responsibility of the surgeon is even more critical when performing a Full Arch Implant treatment. A thorough review of the anatomy is critical prior to the day of surgery to precisely assess the quality and quantity of bone/soft tissues as well as the location of critical anatomical landmarks such as the mandibular nerve, mental nerve, mylohyoid concavity, genial tubercles, floor of the nose, sinus floor, nasopalatine canal, greater palatine canal and pterygoid, zygomatic buttress. A thorough medical review is also a key element to avoid bleeding issues and a poor healing outcome.

Complex Case Rehabilitation in Light of New Technologies
This case report describes a step-by-step full arch restoration (upper and lower), rehabilitated utilizing new technologies in dentistry. CAD/CAM technology has changed not only the technician's working process, but also the clinician's, offering new benefits to clinical workflow.For example the possibility of using zirconia and its characteristics as a restorative material. The clinician's and technician's professional backgrounds and relationships are critical to achieving optimal aesthetic and functional results; while prosthetic success depends upon an in-depth knowledge of the materials and their properties and on carefully performed clinical procedures, which are still of utmost importance to obtain satisfactory results.

Surface Roughness of Restroation Margin Preparations: A Comparative Analysis of Finishing Techniques

Surface Roughness of Restroation Margin Preparations: A Comparative Analysis of Finishing Techniques
This study compared the margin profile and surface roughness created by the tips of four different finishing instruments: fine diamond, dura white stone, tungsten carbide, and ultrasonic diamond-coated tips (UDTs). The aim was to determine which of these instruments produced the smoothest finish and created the most evenly contoured margin characteristics. It was hypothesized that UDTs would produce a rougher dentin surface than a fine diamond bur, that a tungsten carbide bur would provide a smoother finish than a fine diamond, and that the dura white stone would produce an intermediate finish.
