The double arch impression technique: a solution to prevent supraocclusion in the indirect restoration.
The literature relating to inaccuracies in the mounting of casts of semi-adjustable articulators and other factors that influence the fabrication of indirect restorations is reviewed. The effects of such discrepancies often result in "high" cast restorations which require considerable adjustment clinically before definitive placement. Some solutions to "high" cast restorations are offered with indications and contraindications for their use.

A combined direct dowel and indirect core technique.
The dowel-and-core restoration is indicated when inadequate tooth structure remains to retain an extracoronal restoration. A modified technique for fabricating the dowel and core combines the direct technique of forming the dowel in the actual channel with the indirect technique of creating an ideal core contour in the laboratory. This technique allows the operator to create an accurate and passive fit of the dowel pattern in the canal preparation. The technique also introduces the option of retrieving the dowel portion by utilizing a polyvinyl siloxane cast or liner. Further advantages of the technique are reduced chairside time and the ability to capitalize on the preparation of multiple teeth. The technique focuses efforts on achieving an accurate and passive fit of the dowel clinically while delegating the formation of the core to the laboratory.
A modified indirect working die technique for fabricating provisional restorations for multiple teeth.
The "modified" indirect working die technique is introduced. The technique expands the capabilities of the indirect working die technique, which features flexible removable dies for fabricating provisional restorations. The modified technique is distinguished by its potential for restoring multiple teeth, up to and including the complete arch, by utilizing a complete-arch impression tray to which a simple modification is made. It is an accurate, timesaving, and laborsaving method for fabricating provisional restorations.

Case report: impression and maxillo-mandibular relationship recording for construction of obturator prostheses.
The present case report describes a procedure for obtaining the master impression and the maxillo-mandibular relationship for the definitive prosthesis in a maxillectomy patient. After casting the metal framework, a visible-light-cured tray resin was spread over the resin retention grid and gradually cured. Modelling compound was extended over the resin with functional movements, and finally the margins of the defect were sealed with a dental impression wax. A column of light-cured resin was constructed from the lower face of the resin/compound/wax structure to the opposing dental arch. This column permitted recording of the maxillo-mandibular relationship.

A simplified impression technique for dental implants.
Dental implants have been considered an acceptable form of dental treatment since the early 1980s. A number of studies have been published describing impression techniques for dental implants. Many of the techniques described are so complex that they may seem daunting to the average restorative dentist. Most general practitioners do not wish to attempt to restore dental implants. This article describes a very simple, yet extremely accurate, technique for making impressions of dental implant fixtures.
Predictable fixed prosthodontics: technique is the key to success.
This article reviews step-by-step clinical procedures for fixed prosthodontics that include a discussion of the following case parameters: (1) proper diagnosis and case selection; (2) tooth preparation; (3) soft tissue management; (4) impression making; (5) provisionalization; (6) additional laboratory diagnostic information; (7) case try in; and (8) case delivery. When the clinical principles of these procedures are faithfully followed, the success and predictability of any restorative endeavor will be greatly enhanced.

The injection-molded technique for anterior maxillary provisional restorations: a clinical case.
Provisional restorations provide valuable clinical information for the definitive restorations. In the provisionalization phase, they guide the healing of the gingival tissues and allow the clinician to determine any necessary phonetic or aesthetic adjustments; provisional restorations also assuage patients' psychological concerns regarding their appearance. This article highlights the development of provisionalization procedures and describes disadvantages that have furthered the quest for improvements. An alternative technique for fabricating provisional restorations through an injection-molding process is demonstrated for the anterior maxilla.
Important factors for accurate impressions.
A great preparation is only as good as the impression and die made of it. Attention to every detail is necessary for a successful clinical result. By observing the clinical results, each individual dentist's experience will show the observant operator which technique works best. By combining experience, attention to detail, and patience, it is possible to achieve great fitting, adjustment-free esthetic dentistry.
Selection and modification of prefabricated implant abutments according to the desired restoration contour: a case report.
Implant restorations must fulfill the functional and esthetic demands of the patient. The discrepancy in the diameters of an implant and a natural tooth often leads to compromise. The use of prefabricated abutments that can be individually modified offers certain advantages. Selection and modification of the abutment are simpler when a waxup of the restoration is used as a guideline. This article describes a laboratory technique in which the implant abutment is selected and modified according to the waxup of the restoration.
