Bailey Jean Fisher, Angela Spencer, Van Haywood, Gayathri Konchady
It is estimated that 30% of people older than 60 years suffer from hyposalivation or dry mouth. Drinking water frequently has been recommended as a safe, non-pharmacologic way to combat hyposalivation. The saliva in patients with dry mouth is acidic. Beverages consumed daily may have an erosive potential on teeth. The pH and the mineral content of the beverage determine its erosive potential. An acidic beverage, therefore, may have harmful effects on mineralized tooth structures, causing erosion of enamel, dentin, and cementum...

Immediate implant placement can pose challenges surgically and, ultimately, restoratively. Yet immediate placement has become the standard when adequate bone is present to achieve primary stability and site infection is minimal. To avoid prosthetic complications and ensure the implant is encased in bone after healing, proper planning must consider that implant placement does not necessarily need to follow the trajectory of the root socket. As discussed in this article, maxillary anterior sites have potential issues related to the "triangle of bone" that are not encountered in molar sites and demand different approaches to ensure treatment success...

Naif Sinada
Although many approaches to the restoration of edentulous maxillae and mandibles have been developed, these treatments can be costly and time-consuming, and involve extensive grafting of the edentulous ridges. The All-on-4® treatment concept has been shown to be a viable alternative, with limited grafting required, using at least four regular-platform implants to support an acrylic, screw-retained provisional prosthesis before the fabrication of a definitive prosthesis. This case presentation will discuss the use of narrow-platform (3...

Paramolars are relatively uncommon supernumerary molars. Limited cases of bilateral maxillary or mandibular paramolars have been reported. This case report describes bilateral maxillary premolars and their management in a 15-year-old girl, whose chief complaint was food lodgment in these regions. After a diagnosis of bilateral maxillary premolars was made and confirmed by orthopantomogram, both of the paramolars were extracted.

This study examined the influence of finishing procedures on the surface roughness of different formulations of resin-modified glass ionomers (RMGIs) available in capsules compared with standard resin composites (RCs). Disc samples of three RMGIs and two RCs were fabricated using a metal mold (5 mm x 1.5 mm). Samples were randomly divided into seven groups (N = 10) and subjected to finishing and polishing procedures using a combination of carbide or diamond burs, followed by either rubber points or aluminum-oxide discs...

Stephen J Chu, Adam J Mieleszko
With implant-supported reconstructions, gingiva-shaded pink-colored restorative materials serve as an option for replacing both hard and soft tissues cosmetically. This article presents a case report describing restorative treatment for a patient who requested individual crowns and veneers after she had had multiple surgical interventions to replace a failing implant tooth No. 9. In addition to replacement of the implant prosthesis, this case involved restorative papillae reconstruction that was performed to treat interdental recession that had occurred after the surgeries...

Dennis P Tarnow, Stephen J Chu
Type 3 extraction sockets present a unique challenge in that they possess gingival recession indicative of facial hard- and soft-tissue loss. When teeth present with prior disease requiring removal and implant replacement, the treatment strategy incorporates palatal implant positioning as well as proper restorative contour management to compensate for the recession defect, thereby allowing the gingival tissues to heal in the correct 3-dimensional position. This article describes the case of a patient with a nonrestorable maxillary right central incisor with internal resorption...

Xavier Rodríguez, Xavier Vela, Maribel Segalà
Soft-tissue recession around an implant rehabilitation over time has been considered a physiologic phenomenon. The divergent profile of the abutment and the abutment's dis/reconnections are the most critical predisposing and precipitating factors regarding such gingival recession. Recent publications have discussed how tapered and marginless abutments that allow no disconnections and increase soft-tissue thickness could prevent implant rehabilitations from experiencing gingival recession. The objective of this article is to demonstrate the biologic rationale of tissue behavior surrounding tapered abutments and their clinical application...

Anatomical constraints at implant sites often precipitate a conflict between surgical and prosthodontic prerequisites for screw retention of implantsupported prostheses. This article discusses use of a dual-axis implant designed to help clinicians overcome these challenges by facilitating accuracy of surgical placement and prosthetic simplicity, as well as improving biomechanics and enhancing esthetics.

Ernesto A Lee
As the use of dental implants has become more common, so has the frequency of complications and unforeseen outcomes. This article describes the treatment of a complex iatrogenic defect secondary to a failed implant (No. 7) and multiple bone-grafting attempts in the maxillary anterior region. The patient's revealing smile line and high-risk circumstances demanded the use of an interdisciplinary treatment approach with high potential for predictable esthetic results. Forced eruption was performed to restore the alveolar height deficit and develop the compromised hard and soft tissues around teeth Nos...

Achieving a long-term esthetic implant restoration in the maxillary anterior area is sometimes unpredictable. This article reviews several risk indicators of implant mucosal recession and loss of interproximal papillae, and how to prevent these risks. Results obtained from the literature suggest that the following factors are strongly related to implant soft-tissue complications: buccally positioned implant placement, a thin gingival biotype, lack of an adequate amount of keratinized mucosa, implant placement after ridge augmentation procedures, an increased distance of tooth bone peak to the contact point, and an inadequate horizontal implant-tooth distance...

Edward A McLaren, Nathaniel Lawson, James Choi, Juan Kang, Carlos Trujillo
Fabricating all-ceramic restorations with minimal or no application of a secondary phase while maintaining esthetics has been a sought-after goal of the dental profession. The objective has been development of a monolithic material with optical properties similar to the natural tooth without the need for layering porcelain. This article examines some of the newer cubic zirconia materials used in a monolithic form. The authors discuss laboratory-processing issues that affect esthetics, including evaluation of colorizing, sintering, finishing, and polishing, and assess initial translucency testing of several materials while evaluating the effect of air abrasion on flexural strength of these cubic zirconias...

André V Ritter, Newton Fahl, Marcos Vargas, Rodrigo R Maia
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...

Pain from local anesthesia injections can be reduced by distraction and counter-stimulation techniques. This study investigated the DentalVibe® Injection Comfort System (third-generation, DV3), developed to lessen anesthesia pain through pulsed vibration, a form of counter-stimulation. The aim of the study was to evaluate both the efficacy of DV3 in reducing pain and discomfort from intraoral long buccal (LB) and inferior alveolar nerve (IAN) injections and the time needed to achieve complete anesthesia during an IAN block...

#16
Amna Adam Ibrahim, Mohammed Nasser Alhajj, Nadia Khalifa, Magdi Wadie Gilada
Alginate impression (irreversible hydrocolloid) material is commonly used in dental practice because it is easy to mix, low in cost, and well tolerated by patients. The material is not dimensionally stable, however; thus, it is necessary to pour the impression immediately after the molding is accomplished, or within 60 minutes if the impression is kept in 100% humidity. Excessive contact of the alginate impression with the cast model over time may affect the model's properties. In this study, the authors tested the effect of contact time between an alginate impression and type III dental stone on cast model properties...

Andrew Spath, Colby Smith
With the overwhelming acceptance of lithium disilicate and zirconia, the frequency with which dentists have to remove these materials is increasing, and this can be difficult. Proper cement usage for full-coverage crowns with preparations that have retention and resistance can be helpful if in the future the restoration needs to be removed. When removing these modern materials, bur and laser techniques are both effective means, with each having specific benefits. Materials selection and preparation design are vital when considering areas of risk each patient exhibits and the potential need for removal...

Paul S Petrungaro
Dental implants have become a suitable treatment option for patients experiencing tooth loss and a popular choice among clinicians for immediate tooth replacement. Because of modifications in implant designs and development in immediate restoration and loading protocols, dental implant treatment can be reduced to a single procedure instead of multiple processes, hence providing the patient with a streamlined treatment that is typically much less invasive with immediate-tooth replacement. The purpose of this paper is to review the immediate restoration of dental implant(s) procedure and validate its position in treatment protocols by presenting success rates documented for more than 15 years and with 5000 implants...

The "medical model" is a term coined for a set of procedures in which American physicians are trained. For dentistry, the sequentially ordered set of procedures includes: (1) immediate concerns; (2) medical/ dental histories; (3) physical examination findings; (4) ancillary tests, if needed; (5) diagnosis; (6) risk assessment; (7) prognosis without treatment; (8) treatment-plan options/informed consent; (9) treatment; (10) post-treatment assessment and verification. This case report demonstrates a diagnostic system using the medical model via linear thinking-ie, step-by-step progression-to diagnose and conservatively treat a patient with a constricted chewing pattern...
