The article provides a background for understanding the properties of soft liner materials, describing associated problems, and discussing clinical applications of soft liners in dental practice. Although not a panacea, soft liner materials provide the practitioner with a variable tool in providing excellent clinical care for patients.
The purpose of this article is to review and project treatment procedures for areas of esthetic concern. The authors were participants in a consensus conference sponsored by ITI and held in August 2003 in Gstaad, Switzerland. This article deals with the basic prosthetic/restorative aspects in implant esthetics. It is based on a literature review performed by 16 participants from Group 2 (Buser et al) in this section of the Journal.
An often-neglected aspect of fixed prosthodontics is the contour of the tooth adjacent to the cast restoration. The adjacent surfaces should be surveyed to reveal compatibility with the path of insertion of the restoration. Adjacent contacts may have to be altered to permit the placement of the fixed partial denture and to ensure proper contact size/shape and embrasure size. The need for guide planes on teeth adjacent to fixed partial denture abutments in fixed prosthodontics is described.
Pharmacy benefit managers (PBMs) use a variety of pricing strategies. When employers have a thorough knowledge of those strategies, they can use them to their advantage to help manage pharmacy benefits. This article discusses PBM strategies in terms of what employers need to know, the questions employers need to ask and goals employers must keep in mind in order to secure the affordable cost and quality prescription drug management programs that they and their employees need and deserve.
This review of selected articles has discussed the best evidence from clinical studies pertaining to removable prosthodontics. The goal was to correlate recent literature in context with what is clinically significant for the general dentist practicing removable prosthodontics. The focus of this limited review should encourage more interest in seeking valid literature to support and incorporate evidence-based practices into daily prosthodontic treatment decisions. Prosthodontic treatment planning is a complex process that involves a combination of diagnostic information, patient desires, evidence-based outcome data, and a thorough review of the treatment alternatives (1). With appropriate skills and the availability of software to conduct a literature search, evidence-based practice is a powerful means for general dentists to establish the effectiveness of patient treatment decisions and enhance clinical knowledge and skills over the course of a professional career (5).
The South Carolina Estuarine and Coastal Assessment Program (SCECAP) was initiated in 1999 to assess the condition of the state's coastal habitats using multiple measures of water quality, sediment quality, and biological condition. Sampling was subsequently expanded to include components required for the National Coastal Assessment (Coastal 2000) Program. Habitats are classified as either "tidal creeks" (< 100 meters in width) or larger "open water" bodies. Approximately 30 sites are sampled within each habitat during the summer months using a probability-based random sampling design. Results obtained from the first two years of sampling documented significant differences in several water quality parameters (DO, salinity, pH, turbidity, fecal coliform bacteria, total nitrogen, TKN, total phosphorus) and biological measures (chlorophyll-a, finfish and crustacean abundance and biomass and a number of benthic species) between the tidal creek and open water habitats. These differences highlight the value of partitioning shallow water habitats separately from the larger open water bodies traditionally sampled in estuarine monitoring programs, especially since tidal creeks serve as critical nursery areas for many species. Based on the differences observed, there is a clear need to identify different physical and biological thresholds for evaluating the condition of each habitat type.
