Impression matrix technique for cusp replacement using direct composite resin.

UNLABELLED: Placement of Class II composite resin restorations often presents unique challenges in achieving proper contour and contact. Although the use of sectional bands has provided solutions to these problems, their use typically is limited to more ideal cavity preparations. With more extensive loss of tooth structure, recreating the natural tooth contours and contacts with direct resin composite can be difficult. Typically an indirect restoration is the treatment of choice when a cusp is lost. However, situations may arise that require the use of direct resins for cusp replacement. This article describes the use of an impression matrix to facilitate the replacement of missing tooth structure and allow the dentist to use sectional bands in certain cusp loss situations. CLINICAL SIGNIFICANCE: When applicable, the impression matrix provides a significant saving in time and effort in cusp replacement with direct composite resins.

Shade-match perception of porcelain-fused-to-metal restorations: a comparison between dentist and patient.

BACKGROUND: Patient satisfaction with the shade match of restorations has not been appraised carefully in the dental literature. This study compared patients' and a prosthodontist's satisfaction with the shade o f existing porcelain-fused-to-metal, or PFM, restorations. METHODS: The authors selected a convenience sample of 212 patients for this study. Patients and a prosthodontist were asked independently, under standardized conditions, to express their satisfaction with the shade match of the patient's restoration. Kendall's tau-b statistic was used to measure the strength of the association between the shade satisfaction rating of the patient and that of the prosthodontist. The authors also examined patient satisfaction with respect to sex, treatment location and clinician. RESULTS: The prosthodontist was less satisfied than the patient with the shade match in a significant number of cases. The authors found no difference in patient satisfaction with respect to sex. They did find that patients were more satisfied with the shade match of restorations placed by a prosthodontist or placed under the supervision of a prosthodontist than they were with restorations placed by general practitioners. CONCLUSIONS: Patients were more satisfied with the shade match of their PFM restorations than was the prosthodontist. Patients also were more satisfied with restorations placed by a prosthodontist or placed under the supervision of a prosthodontist in a hospital or academic setting. Clinical Implications. Patient satisfaction with shade match is important when constructing or replacing a restoration, and the level of satisfaction might be different from that of the clinician. When selecting restoration shades, clinicians should take into consideration the opinions of their patients.

Evaluation of a glass-fiber-reinforced, bonded, inlay-supported fixed partial denture--4-year results.

Glass-fiber-reinforced composite resin systems may be used as conservative alternatives to conventional fixed partial dentures (FPDs) for the replacement of a single missing tooth. This article describes a clinical technique and 4-year evaluation of an inlay bonded FPD. The patient presented with a missing maxillary right second premolar. A high-caries risk and moderate-to-advanced attachment loss around the abutment teeth, which were clinically stable, were noted. The patient had a strong desire to maintain his remaining dentition. Advantages of supragingival margins and minimal tooth structure removal made the bonded inlay bridge a viable alternative to a conventional FPD for this compromised restorative situation. The clinical performance of this glass-fiber-reinforced resin inlay FPD at the 4-year follow-up is provided. The restoration has served satisfactorily for more than 4 years and holds promise as a conservative, esthetic alternative to the conventional FPD in certain clinical cases.

Restoring erosion associated with gastroesophageal reflux using direct resins: case report.

Gastroesophageal reflux disease (GERD) is a condition where stomach acids are chronically regurgitated into the esophagus and oral cavity, resulting in pathology, such as esophagitis, varices or ulcers. Continual exposure of the teeth to these acids can also cause severe dental erosion. This condition frequently is asymptomatic, and the only evident sign may be the irreversible erosion of tooth structure. The dentist often is the first health care professional to identify the affected dentition. Knowledge of this cause and effect relationship between GERD and dental erosion will better prepare the practitioner to refer patients for appropriate diagnosis and treatment of the underlying medical condition and provide treatment for the affected teeth. This article presents a case report where dental erosion was present due to GERD. After management of the disease with medication, dental treatment of the eroded dentition is described, including diagnosis, treatment planning and restorative reconstruction.
