Selection of luting agents, part 1.

The clinical success of indirect restorations is dependent on multiple factors that include preparation design, mechanical forces, restorative material selection, oral hygiene, and selection of a proper luting agent. The selection of the luting agent is dependent on the specific clinical situation, the type of restoration utilized and the physical, biologic, and handling properties of the luting agent. Although it is important to choose the best luting agent for each clinical situation, far greater variations in physical properties result from improper manipulation of a given luting agent than exist between different types of cements. One study listed loss of retention as the third-leading cause of prosthetic replacement, with failure occurring after only 5.8 years in service. The primary purpose of the luting procedure is to achieve a durable bond and to have good marginal adaptation of the luting material to the restoration and tooth. Conventional cements have always relied upon retention and resistance forms in tooth preparations; Adhesive-type luting agents offer the clinician an added advantage by bonding to the tooth structure. Three main types of conventional "cements" are commonly used, zinc phosphate and the polyelectrolyte cements polycarboxylate, and glass ionomer cements. Because of its long history of successful clinical use, zinc phosphate is considered the gold standard against which all other luting agents are compared because of its long clinical history of successful use. Currently, two additional types of luting agents have gained considerable popularity. These include the resin-modified glass ionomer cements and resin cements. The resin cement category includes light-cured, dual-cured and chemically cured agents. The purpose of this article is to discuss the ideal attributes of a luting agent and make clinical recommendations for their use.

Use of a removable partial denture in the management of chronic screw loosening.

Lack of posterior support can result in adverse occlusal forces being placed on anterior teeth. These forces may cause fremitus, splaying of the anterior teeth, and even accelerated wear. When implant-supported restorations are used, a common indicator of overload is screw loosening. This clinical report demonstrated conservative management of a patient who presented with multiple episodes of screw loosening of an implant-supported restoration replacing the maxillary left incisor secondary to developing reduced posterior support. Ideal treatment would be to re-establish posterior support by means of implant-supported restorations; however, this option was constrained by finances.

An interdisciplinary approach to treatment planning in implant dentistry.

The practice of implant dentistry requires an interdisciplinary approach that integrates the knowledge, skills, and experience of all the disciplines of dentistry into a comprehensive treatment plan. The team must examine the anticipated restorative site to determine the suitability of the existing hard and soft tissues for implant placement. Deficiencies in hard and soft tissue, which prevent ideal implant placement, must be recognized and addressed to ensure a more predictable esthetic outcome. This article outlines a comprehensive interdisciplinary treatment philosophy designed for developing the foundation of optimal esthetics in implant dentistry. Cases are presented to illustrate the utility of interdisciplinary treatment in which specialists are recruited to enhance and improve a patient's dental function and esthetics.

To extract or not to extract? Factors that affect individual tooth prognosis.

A dentist evaluates a natural tooth for its quality of health. Once this is accomplished, the clinician obtains an estimate of longevity and decides whether to extract or to treat and maintain the tooth. There often are questions and doubts involved in the decision-making process in regard to the prognosis of an individual tooth. Unfortunately in dentistry, as in all biologic sciences, there are no straightforward answers to questions. This article will look at the literature in this area to help the practitioner in the decision-making process with regard to the compromised tooth. The article will concentrate on the single tooth or implant restoration. Other factors, such as the strategic value of a tooth and financial limitations in relation to long-term prognosis, will also be discussed.

An interdisciplinary approach to treatment planning in the esthetic zone.

The practice of prosthodontics requires a multidisciplinary approach that integrates the knowledge, skills, and experience of all the disciplines of dentistry into a comprehensive treatment plan. This article outlines a comprehensive interdisciplinary treatment philosophy designed for developing the foundation for optimal esthetics in fixed prosthodontics. Cases are presented to illustrate the utility of interdisciplinary treatment in which specialists are recruited to enhance and improve a patient's dental function and esthetics.
