Computer-aided design and manufacturing technology enables practitioners to create, in a single appointment, indirect restorations that are esthetic and functionally unique to the patient's situation. The popular effort to perform minimally invasive dentistry using digital techniques with chairside milling can lead dentists to novel individualized restorative treatment. This article demonstrates a conservative anterior partial coverage restoration, utilizing both digital technology and chairside ceramic characterization to achieve an optimal esthetic outcome while preserving healthy tooth structure...

The interest in repairing failed restorations has been growing; such a procedure may prolong the life span of defective direct and indirect dental restorations. The intraoral repair using resin-based composite materials has major benefits, as it preserves the main body of the restoration, avoids unnecessary removal of sound tooth structure, is an easy and fast treatment, avoids additional appointments, and is inexpensive. This case report demonstrates the use of nanohybrid Ormocer®, or organically modified ceramic, materials...

A modified polyetheretherketone (PEEK) framework material veneered with indirect light-polymerized composite resin was used as an alternative material for the fabrication of an endocrown restoration for an extensively damaged molar. The elastic modulus of the polyetheretherketone framework (4 GPa) veneered with indirect composite resin could dampen the occlusal forces protecting tooth structures better than ceramic materials. This is important in the restoration of extensively damaged molars with weak roots...

The muscle segment homeogenes Msx1 and Msx2 play a major role in tooth and bone formation. Periodontal osteoclast impairment also occurs in Msx2 null mutant mice, which is restored by overexpression of the receptor activator of NF-κB targeted in osteoclast lineage. Here, we investigated the role of Msx2 in dentinogenesis. Experiments were performed on Msx2(-/-) mice and the MDPC-23 odontoblastic cell line. After Msx2 gene silencing, real-time quantitative RT-PCR data showed significant overexpression of Runx2, Bglap, Dspp, and Alpl...

The resin-bonded fixed partial denture (RB-FPD) is the first restorative treatment option to be considered in cases where one or more teeth are missing. The indications for implants, conventional FPDs, and adhesive FPDs, considering the general and dental conditions of the patient, are discussed in this article. When the RB-FPD is the chosen option, a direct or indirect technique, a cantilever-type or fixed-fixed design, and materials to be used need to be selected. The choice will depend on a variety of factors, such as interproximal space at the connector area, anterior or posterior location, the skills of the dentist, esthetics, and the patient's wishes...

OBJECTIVE: The optical integration (OI) of monolithic CAD/CAM materials under 4 illuminations was evaluated using a standardized and clinically relevant method. MATERIALS AND METHODS: Eighteen inlays were manufactured and placed (glycerin gel). Standardized photos were taken under 4 illuminations (neutral white light direct and indirect illumination, cross-polarized light, fluorescent light). Six evaluators defined the optical integration score (OIS) as the "visibility" of the restoration (0 = worst OI, 4 = optimal OI)...

Restorative procedures are accompanied by a reduction of tooth stability, a decrease of fracture resistance, and an increase in deflection of weakened cusps. The choice between a direct or an indirect restorative technique, mainly in posterior areas, is a challenge, and involves biomechanical, anatomical, functional, esthetic, and financial considerations. In this article, the pros and cons of direct restorations are examined, as well as an analysis of indirect restorations and an overview of dental ceramics...

OBJECTIVE: Therapeutic options for dental trauma depend on the injuries' features. For patients with uncomplicated tooth fractures, adhesive materials and composite partial veneers may be a therapeutic solution that completely preserves healthy tooth structure. CLINICAL CONSIDERATIONS: An ultra-conservative approach, using indirect composite partial veneers to restore fractured anterior teeth is described in these case reports. CONCLUSION: Despite the position of the finish line in the middle of the clinical crown, this solution offers functional and esthetic outcomes using an indirect composite technique, and appears to be a suitable alternative to direct composite restorations or less conservative indirect veneers...

REVIEW
Andrew MacInnes, Andrew F Hall
Cuspal-coverage restorations are important to preserve the integrity of a weakened tooth against the forces of occlusion. This article discusses the clinical indications for both direct and indirect cuspal-coverage restorations and the evidence supporting their use. Factors that modify a tooth's ability to dissipate normal occlusal forces and the effect cuspal-coverage restorations have on force distribution are examined. Clinical criteria, choice of restorative material and methods for tooth preparation are also discussed...
