Louis H. Bauer and the origins of civil aviation medicine.

With the passage of the Air Commerce Act in May 1926, civil aviation safety became a federal responsibility under the Department of Commerce (DoC). In November of that year, Louis Hopewell Bauer (1888-1964) became the DoC's first Aviation Medical Director. After earning his medical degree at the Harvard School of Medicine in 1912, Bauer joined the U.

Recontouring teeth and closing diastemas with direct composite buildups: a clinical evaluation of survival and quality parameters.

Objectives: Irregular tooth shape and position in the anterior maxilla and mandible are major aesthetic problems for patients. In recent years such conditions have increasingly been treated minimally or even non-invasively by recontouring teeth with direct composite resin buildups. Although clinical experience with this treatment option is promising, evidence-based data about longevity are limited.

Fiber-reinforced composite fixed dental prostheses: a retrospective clinical examination.

Purpose: To obtain survival data on 32 fiber-reinforced fixed dental prostheses which were inserted in our department and to rate the quality of these restorations on the basis of esthetic, biological, and functional parameters.

Materials And Methods: Thirty-two patients with fiber-reinforced fixed dental prostheses were included in the study. The fiber frameworks were made of a polymer-monomer-preimpregnated continuous unidirectional glass fiber material.
