M B Blatz, M Vonderheide, J Conejo
Digital manufacturing, all-ceramics, and adhesive dentistry are currently the trendiest topics in clinical restorative dentistry. Tooth- and implant-supported fixed restorations from computer-aided design (CAD)/computer-aided manufacturing (CAM)-fabricated high-strength ceramics-namely, alumina and zirconia-are widely accepted as reliable alternatives to traditional metal-ceramic restorations. Most recent developments have focused on high-translucent monolithic full-contour zirconia restorations, which have become extremely popular in a short period of time, due to physical strength, CAD/CAM fabrication, and low cost...

The objective of this follow-up study was to examine the performance of Cerec 1 inlays and onlays in terms of clinical quality over a mean functional period of 25 years. Out of 200 Cerec 1 inlays and onlays placed consecutively in 108 patients in a private practice between 1989 and early 1991, 141 restorations could be reevaluated in 65 patients after up to 26 years and 10 months. All ceramic inlays and onlays had been generated chairside using the Cerec 1 method, and had been seated adhesively using bonding composite...

Marco Veneziani
The aim of this article is to identify the indications for adhesively cemented restorations and to provide a correct step-by-step protocol for clinicians. New cavity preparation principles are based on morphological considerations in terms of geometry (maximum profile line and inclination of cusp lines), and structure (dentin concavity and enamel convexity). In this article, we discuss previous preparation concepts that were not designed purely for adhesive restorations and were therefore not conservative enough or suitable for adhesive procedures...

In the direct-indirect composite technique, composite is applied to a nonretentive tooth preparation (eg, a noncarious cervical lesion or a veneer/inlay/onlay preparation) without any bonding agent, sculpted to a primary anatomic form, and light-cured. The partially polymerized restoration is then removed from the preparation and finished and tempered extraorally chairside. The finished inlay is bonded to the preparation using a resin-based luting agent. Advantages of this technique include enhanced physical and mechanical properties afforded by the extraoral chairside tempering process because of increased monomer conversion, and greater operator control over the final marginal adaptation, surface finishing and polishing, and anatomy of the restoration, given that these elements are defined outside of the patient's mouth...

To examine the bonding state of metal-free CAD/CAM onlay restorations made from two popular resin composite blocks and a typical glass-ceramic block after cyclic loading, with and without immediate dentin sealing (IDS). Standardized mesial-distal-occlusalbuccal (MODB) cavities in 24 extracted human molars were prepared. The intra-cavity dentin surfaces of half of the cavities were immediately sealed with all-in-one adhesive and flowable composite, while those of the other half were not. All cavities were scanned, from which CAD/CAM onlays were fabricated from three types of block and cemented with an adhesive resin cement system...

A significant number of patients undergo mastectomies and breast reconstructions every year using many surgical-based techniques to reconstruct the nipple-areolar complex (NAC). Described herein is a tissue engineering approach that may permit a human NAC onlay graft during breast reconstruction procedures. By applying decellularization, which is the removal of cellular components from tissue, to an intact whole donor NAC, the extracellular matrix (ECM) structure of the NAC is preserved. This creates a biologically derived scaffold for cells to repopulate and regenerate the NAC...

Neourethral diverticulum secondary to distal neourethral stenosis is not uncommon after proximal hypospadias repair. We describe a technique using the neo urethral diverticular roof and overlying skin as a composite flap to reconstruct the urethral stenosis distal to the diverticulum. The composite flap is advanced distally for reconstruction of the stenosed urethra either as a tube or as an onlay. Urethra at the diverticular bed is tubularized to reduce its caliber. This technique has yielded excellent results in three children...

Zirconia has become one of the most popular materials in dentistry. New high-translucent zirconia ceramics have favorable optical properties and can be applied as monolithic full-contour restorations in various clinical indications for posterior and anterior teeth. However, having reliable cementation protocols is fundamental for clinical success of indirect ceramic dental restorations, including those made from zirconia materials. Resin bonding supports ceramic restorations and is necessary for onlays, laminate veneers, and resinbonded fixed dental prostheses...

BACKGROUND: Because of the many possibilities for endodontically restoring the posterior teeth and the high prevalence of restoration failures, this topic continues to be of major concern. A composite resin (CR) restoration reinforced by a horizontal fiberglass post may improve the fracture resistance of endodontically treated teeth. The authors investigated this possibility by comparing the fracture resistance of molars restored with direct techniques with that of molars restored with indirect techniques...

When patients are constrained financially to receive dental work, a staged approach can be an effective way for enabling treatment to proceed. In this case, a patient who had been in the practice for about 10 years and had a severely worn and eroded dentition finally opted to receive treatment in stages. A systematic approach was used to determine the proper postoperative position of the teeth. The subsequent treatment plan included the use of porcelain onlays and full-coverage crowns in the mandibular posterior along with provisional direct composite restorations in the maxillary dentition; the composites would be transitioned to porcelain crowns as the patient's finances would allow...

To date, treating vertical food impaction with open contact effectively, especially with an atraumatic therapy, remains a challenge. In this study, we developed a simple, atraumatic, and economic therapeutic measure to treat vertical food impaction. The scientific rationale of our therapeutic technique is to restore an intact and firm proximal contact with proper location and form relationships to prevent forceful interproximal wedging of food, which in turn protects interdental papilla. We performed the procedure using flowable composite resin or composite resin cement with the aid of a cerclage wire under tension to rebuild the contact area...
