Esthetic, biologic and restorative considerations in coronal segment reattachment for a fractured tooth: a clinical report.

Reattachment of a fractured clinical crown involving minimal invasion of the biologic width can be accomplished without conventional ostectomy and crown lengthening so that satisfactory esthetics can be achieved. Adhesive techniques sometimes in conjunction with traditional mechanical retention, such as a post, can be used to reattach the fractured segment. An esthetic result can be obtained with a minimal number of procedures and cost to the patient.

Ceramic inlay fabrication with three-dimensional copy milling technology--Celay.

Efforts to improve the physical properties of ceramic materials have resulted in the development of restorations that are machined from preformed ceramic blocks. Celay is a system that uses micromilling technology to prepare these ceramic blocks for fabrication of inlays, onlays, veneers, and crown restorations. Celay restorations can be luted, using advances in composite adhesive techniques. These restorations are exceptionally esthetic because of a "chameleon effect," and they exhibit a high degree of marginal accuracy. A clinical case, included in this article, illustrates the technology and use of this innovative restorative system.

Ceramic optimized polymer: the next generation of esthetic restorations--Part 1.

An abundance of new materials and techniques that challenge the clinician to recommend and provide the appropriate restoration for each clinical situation have been developed in the last decade. A new generation of materials, described by manufacturers as ceramic optimized polymers, have been recommended for a wide variety of restorations including inlays/onlays, crowns and bridges, and direct restorations. In this article, the appropriate preparation and luting technique for inlays/onlays are delineated. The use of ceromer inlays/onlays for teeth exhibiting symptoms of the partially fractured tooth is demonstrated.

Coronoradicular rehabilitation with a carbon-fiber post.

Endodontically treated teeth present a myriad of problems because of coronal destruction from caries, previous restorations, and coronal access. Previously, a post was considered necessary to strengthen a tooth and to resist intraoral forces. However, recent research has indicated that not all endodontically treated teeth require a post, core, and crown. Each clinical situation must be evaluated and the need for a post and/or the appropriate post determined. The recent introduction of a carbon-fiber post may reduce some of the problems inherent with metal posts. Proper placement, advantages, and disadvantages are discussed.

Microleakage of Class V composite, resin sandwich, and resin-modified glass ionomers.

PURPOSE: To evaluate in vitro the extent of microleakage of Class V cavities restored with composite, and resin-modified glass ionomers. MATERIALS AND METHODS: Class V cavities were prepared in 35 extracted teeth and randomly divided into seven groups of five teeth each (10 restorations in each group). Group 1: Scotchbond Multi-Purpose Adhesive (SMP) and restored with Z100 resin placed with an incremental technique, Group 2: Lined with GC Fuji lining LC and restored with SMP and Z100. Group 3: Based with Fuji II light-cured glass ionomer restorative and restored with SMP and Z100. Group 4: Lined with Vitrebond and restored with SMP and Z100. Group 5: Based with Vitremer and restored with SMP and Z100. Group 6: Restored with Fuji II LC. Group 7: Restored with Vitremer. The teeth were subjected to thermocycling, stained with silver nitrate, then longitudinally sectioned. Dye penetration at the tissue/restoration interface was scored based upon the extent and location of the precipitated silver. RESULTS: All groups demonstrated minimal or no microleakage at both the enamel and gingival sites.

Esthetic restoration of a single-tooth implant using a precision ceramic coping.

Previously, osseointegrated implants were used almost exclusively for edentulous arches. In recent years, the development of abutments has allowed more esthetic restorations of single and multiple abutments. The recent introduction of a precision ceramic coping for single-tooth implants has enabled the restorative dentist to achieve a highly esthetic result. Proper treatment planning, surgical-guide fabrication, and technique of placement for the various components are addressed in this article.

Replacement of congenitally missing lateral incisors with ceramic resin-bonded fixed partial dentures.

Congenital absence of teeth may accompany palatal clefts; various replacements are available and include conventional fixed partial dentures (FPDs), implant-supported artificial crowns, and resin-bonded FDPs. Orthodontic and restorative dentistry consultations are essential for appropriate treatment. The recent introduction of an all-ceramic resin-bonded FPD provides an esthetic prosthesis.
