An intraoral lift technique for refining porcelain margins

A method has been described by which a paste of shoulder porcelain and light-curing resin is used to correct deficient porcelain margins. The resin-bonded porcelain is fired in an oven for final hardening.     

Esthetic repair of porcelain in a complete-mouth reconstruction: a case report.

This paper presents a relatively simple method of repairing a large porcelain fracture in a porcelain-fused-to-metal crown that is part of a multi-unit fixed partial denture. The technique involves fitting a "modified" porcelain-fused-to-metal crown over the original damaged crown following some preparation of the original crown. This technique is of special value when a permanently cemented multi-unit restoration is involved, eliminating the need to replace the entire restoration and providing a durable esthetic result.     

An alternate method for establishing porcelain margins

The technique described is simple, safe, and requires no special training or expertise in its application. Hi-Temp special liquid is readily available and has an indefinite shelf life. The technique enables easy fabrication of ceramometal crowns with porcelain margins with fewer problems and greater accuracy.     

Esthetic management of perimolysis with porcelain laminate veneers

This report deals with the dental manifestations of bulimia nervosa. Differential diagnosis of perimolysis was identified and compared with other manifestations of systemic or exogenous causal factors. Conservative cosmetic dental management of the dental erosion that occurred as a result of bulimia nervosa was described and discussed in comparison with other currently accepted treatment modalities.     

Esthetic provisionalization for a combined porcelain veneer and anterior single crown case

This article presents a technique for the fabrication of provisional veneers when a single full-coverage anterior restoration is involved. A case that includes seven porcelain veneers and one all-ceramic crown is discussed.     

Esthetic alternatives for posterior teeth: porcelain and laboratory-processed composite resins.

Porcelain and laboratory-processed composite inlays and onlays are enjoying increasing popularity as a result of heightened patient concern over the esthetics and biocompatibility of restorative materials. This paper reviews current clinical concerns about porcelain and indirect composite restorations, focusing on indirect procedures, microleakage, technique sensitivity, long-term serviceability, finish and polish, abrasion, and wear resistance. The available data indicate that there are still significant limitations to the routine use of these esthetic alternatives for posterior restorations.     

Esthetic correction of gingival recession using a modified tunnel technique and an acellular dermal connective tissue allograft

Esthetic correction of gingival recession is an important goal of periodontal therapy. This article describes a surgical technique that combines a modified tunnel technique and an acellular dermal connective tissue allograft. With the aid of vertical incisions, a tunnel is created under the buccal mucosa of the affected tooth. These incisions enable easy access for graft placement and create mobility for gingival coronal positioning. The use of an acellular dermal connective tissue allograft eliminates the need for a surgical palatal donor site. This minimizes postsurgical complications.

CLINICAL SIGNIFICANCE

The combination of a modified tunnel technique and an acellular dermal connective tissue allograft permits esthetic root coverage in a manner that reduces postsurgical complications.     

Esthetic restorations of maxillary anterior teeth with orthodontic treatment and porcelain laminate veneers: a case report

If orthodontists and restorative dentists establish the interdisciplinary approach to esthetic dentistry, the esthetic and functional outcome of their combined efforts will be greatly enhanced. This article describes satisfying esthetic results obtained by the distribution of space for restoration by orthodontic treatment and porcelain laminate veneers in uneven space between maxillary anterior teeth. It is proposed that the use of orthodontic treatment for re-distribution of the space and the use of porcelain laminate veneers to alter crown anatomy provide maximum esthetic and functional correction for patients with irregular interdental spacing.     

Marginal adaptation of porcelain margins in metal ceramic restorations.

The purpose of this study was to evaluate the marginal adaptation of all-porcelain labial margin metal ceramic crowns using a porcelain shoulder material containing a light-polymerizing resin and one that used a direct-lift technique. Conventional metal margin restorations served as controls. Scanning electron micrographs were made of a 1-mm mesiodistal width of the margin at midfacial and midlingual reference marks. Image processing and analysis techniques were accomplished using a computer. Statistical evaluation indicated that the mean labial marginal discrepancy of the control group was significantly less than that of either of the two porcelain shoulder methods.
