Is There Space for Resin Composite Restorations in a World of CAD-CAM and Digital Dentistry? Two-Year Follow-Up of Clinical Outcomes Using the Direct-Indirect Technique.

Objective: This clinical report seeks to elucidate the versatility and mid-term outcomes of the direct-indirect technique. It presents a comprehensive step-by-step protocol for restoring anterior dentition across various clinical scenarios in accordance with the principles of the polychromatic layering technique.

Clinical Considerations: This clinical report was divided into two phases.

The Impact of Modeling Liquids on Surface Roughness and Color Properties of Bulkfill Resin Composites After Simulated Tooth Brushing: An in Vitro Study. Part I.

Objective: To evaluate the effect of different modeling agents on color changes, surface roughness, and translucency parameters over time in Bulkfill resin composites.

Material And Methods: Sixty specimens were prepared using three Bulkfill resin composites (Tetric N-Ceram Bulkfill, Filtek One Bulkfill and Opus Bulkfill) and three modeling agents (Wetting Resin, Optibond FL and Ambar APS). All specimens were subjected to a simulated tooth-brushing (Baseline, 50.

Nature-mimicking layering with composite resins through a bio-inspired analysis: 25 years of the polychromatic technique.

Objectives: For decades, the dental community has discussed which materials would be the ideal substitutes for lost tooth structure. Initially, the biomimetic approach advocated that feldspathic ceramics would be the material of choice for enamel. However, given the complexity of obtaining excellent dental technicians and the financial cost, are composite resins a suitable replacement? The optical properties with opalescence and fluorescence effects, as well as this material's high fracture toughness, indicate it as a long-lasting restorative material.

Marginal and Internal Adaptation of Cervical Restorations Using Direct, Direct-indirect, and Indirect Techniques.

Objective: This study aimed to evaluate the external and internal adaptations of cervical restorations using different restorative techniques.

Methods: Forty extracted and intact human premolars received standardized cervical preparations to simulate non-carious cervical lesions. The teeth were randomly divided into four groups (n=10) according to the restorative technique: D, direct composite restoration without a base (Palfique LX5, Tokuyama Dental Corp Inc, Tokyo, Japan); DB, direct composite restoration with a flowable composite liner (Estelite Flow Quick -High Flow, Tokuyama Dental Corp Inc); DI, direct-indirect composite restoration bonded with flowable composite; and I, indirect restoration bonded with flowable composite.

The beyond the gap filling approach: Modeling facial and interproximal tissues and improving esthetics for anterior flapless immediate implant placement.

Objective: Maintenance of adequate interproximal tissue height between an implant and a natural tooth or between adjacent implants represents an esthetic challenge in implant dentistry. The aim of this case report is to describe a modified technique referred to as the beyond the gap filling (BGF) approach designed to improve the horizontal and vertical components of the facial aspect and particularly the height of interproximal bone peaks around immediately placed implants into fresh extraction sockets.

Clinical Considerations: Four patients (five teeth) requiring anterior tooth extraction were treated with the BGF approach that included: (a) minimally traumatic tooth extraction; (b) immediate implant placement without flap elevation; (c) installation of a narrow profile healing abutment to protect the implant during grafting; (d) grafting with a construct with 90% bovine bone granules and 10% porcine collagen packed coronally to the facial and interproximal bone walls above the level of the bone crest; and (e) delivery of an immediate restoration.

Composite veneers: The direct-indirect technique revisited.

Objective: This article provides an update on the direct-indirect composite veneer technique.

Clinical Considerations: Composite veneers have long been used as a conservative and esthetic treatment option for anterior teeth. While they are generally performed using a direct technique, there has been renewed interest in the direct-indirect composite veneer technique because of its advantages and broad indications for restoration of tooth color and morphology.

State of the Art of Dental Adhesive Systems.

Background: The large dependence on a dental substrate type to bond strength has leveraged the research on materials and techniques that perform different clinical behavior, promoting a stable bonding over time. Bonding to tooth structure has different clinical behaviors and is dependent on several factors.

Objective: The aim of this paper is to reflect on the state of the art of adhesive systems after the emergence of Buonocore's experiments in current days.

The Direct-Indirect Technique for Composite Restorations Revisited.

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.

Effect of thermocycling and varying polymerization techniques on the restorative interface of class V cavities restored with different composite resin systems.

Background: To evaluate marginal microleakage of two composite resins - a methacrylate- and a silorane-based submitted to different polymerization techniques and thermocycling.

Material And Methods: Ninety-six class V cavities were prepared in sound human molars and restored under different polymerization and thermocycling regimens. The adhesive systems employed were Adper Scotchbond Multipurpose and Filtek P-90 for cavities restored with Z250 and P-90.

Shading concepts and layering techniques to master direct anterior composite restorations: an update.

Creating perfect direct composite restorations has been for long time a strict challenge due to many materials' limitations impacting either shade integration or surface quality, and possibly colour stability. Next to technological drawbacks, a certain complexity and lack of predictability in clinical application was inherent to the technique and made it elitist for a long time. Shading and layering concepts then progressively evolved from a simplistic, non histo-anatomical, bilaminar technique to a multi-layering approach (3 to 4 or more layers), following the Vita Classic system.

Direct-Indirect Class V Restorations: A Novel Approach for Treating Noncarious Cervical Lesions.

Unlabelled: Noncarious cervical lesions are highly prevalent and may have different etiologies. Regardless of their origin, be it acid erosion, abrasion, or abfraction, restoring these lesions can pose clinical challenges, including access to the lesion, field control, material placement and handling, marginal finishing, patient discomfort, and chair time. This paper describes a novel technique for minimizing these challenges and optimizing the restoration of noncarious cervical lesions using a technique the author describes as the class V direct-indirect restoration.
