Simplified impression technique for implant-supported crowns.

Dental implants have become a widely accepted method for replacing missing teeth. While many oral surgeons and periodontists are actively involved in the surgical placement of dental implants, many general dentists do not perform such placements because they are intimidated by the seeming complexity of the procedures and hardware. In response to perceived complexity, dental implant manufacturers have developed implant systems that facilitate and simplify impression taking. As such simplified protocols become more common, implant-borne restorations will become more widely used by the profession as a routine treatment modality. This article describes a simple technique for restoring a single-tooth posterior Straumann implant.

Oral rehabilitation of a young adult with hypoplastic amelogenesis imperfecta: a clinical report.

This clinical report describes the oral rehabilitation of a young adult patient diagnosed with hypoplastic amelogenesis imperfecta. The specific objectives of this treatment were to eliminate tooth sensitivity while enhancing esthetics and restoring masticatory function. Treatment included removal of several teeth, lengthening of the maxillary and mandibular clinical crowns, and placement of anterior and posterior metal-ceramic fixed partial dentures. The 2-year recall examination revealed no pathology associated with the rehabilitation, and the patient's esthetic and functional expectations were satisfied.

Did we push dental ceramics too far? A brief history of ceramic dental implants.

Humankind has developed and used ceramics throughout history. It currently has widespread industrial applications. Dental ceramics are used for fabricating highly esthetic prosthetic denture teeth, crowns, and inlays. However, ceramic's biocompatibility and compressive strength are offset by its hardness and brittleness. Nonetheless, a single crystal sapphire aluminum oxide endosseous implant was developed in 1972 as an alternative to metal. It was more esthetic than its metallic counterparts and was eventually produced in a variety of shapes and sizes. Clinical studies demonstrated its excellent soft and hard tissue biocompatibility, yet the range of problems included fractures during surgery, fractures after loading, mobility, infection, pain, bone loss, and lack of osseointegration. Ultimately, single crystal sapphire implants fell into irredeemable disfavor because of its poor impact strength, and dentists and surgeons eventually turned to other implant materials. However, bioactive ceramic coatings on metal implants have kept ceramics as a key component in dental implantology.

Perceptions of dental schools from within and outside the university.

Perceptions of dental schools held by high-level administrators of their parent institutions and officials in the local community have great potential to influence the future of dental education. The intent of this investigation was to gain a preliminary knowledge of such perceptions at seven institutions in the United States and to use this information to formulate hypotheses that can provide the basis for further targeted investigations that provide evidence useful in decision making and planning processes within dental schools. Interviews with university administrators, executive directors of state dental associations, and state government officials in seven areas of the United States were conducted. The hypotheses drawn from these interviews are: 1) dental schools are generally too insular and need to interact more with their parent institutions and external community; 2) dental schools need to systematically and continually get the message of the value of their services out to the public and political constituencies; and 3) multidisciplinarity and integration with other units are important to university administrators but largely outside the concerns of those external to the university. We suggest that these hypotheses form the basis of subsequent, more targeted, follow-up investigations with the intent of formulating specific recommendations for action.
