Restoring Pink and White Esthetics | Case Type III
By Rita A. Tempel, DDS, AAACD

Finding just the right Case Type III (tooth replacement) for AACD Accreditation can be a challenge. When a difficult case presents itself, it is important to treatment plan, document, and treat the case with ideal principles of smile design. Collaboration between the restoring cosmetic dentist, master ceramist, implant surgeon, and patient is the key to success in transforming a smile. Most importantly, using provisionals or restoration prototypes with the appropriate emergence profiles and interproximal contact points will influence soft tissue contours, resulting in ideal pink and white esthetics.
In cosmetic dentistry, creating a harmonious smile begins with a well-thought-out plan. The AACD photographic series, diagnostic casts, a facebow, and a dentogingival or pink and white diagnostic wax-up are effective tools for analyzing as well as communicating smile design principles with a patient. Since gingival contours have a direct impact on pink and white esthetics, the wax-up is the first step in smile rehabilitation.

Esthetic Overlays | Patient visualization of esthetic procedures
By Matthew R. Roberts, CDT, AAACD and James Fondriest, DDS, FACD, FICD

Patient visualization of esthetic procedures is a fundamental step in the treatment communication process. Historically, the use of direct mockups has been the best way for patients to visualize outcomes prior to esthetic treatment, but that requires a great deal of chair time and artistic ability. More recently, digital photography and software programs have been employed, as have two-dimensional line drawings placed over photographs. A silicone matrix of a diagnostic wax-up using one of the liquid provisional materials can be tried over existing teeth, but is messy to clean up. Esthetic overlays, composed of milled polymethyl methacrylate and based on a facially generated digital design, fit over existing dentition quickly with no cleanup and are a quick and effective way of showing a patient what is possible with cosmetic treatment. This article discusses the process by which these overlays are fabricated and describes a clinical case in which their use helped a patient overcome his concerns about final treatment results.

Minimally Invasive Full-Mouth Reconstruction with V-Shaped Veneers | In Treatment of Bulimia-Induced Dental Erosion
By Dr. Łukasz Lassmann

The incidence of bulimia appears to be increasing, but diagnosing it can be difficult, especially because many patients are too embarrassed to admit to having it. This disorder should be differentiated from occlusive, nutritional, and gastrointestinal problems, as well as from numerous parafunctions. The correct diagnosis allows the dental clinician to choose a treatment that should solve all of the patientís esthetic and functional problems with a minimum number of procedures. With a minimally invasive approach in erosive patients, it is necessary to know the decision criteria for increasing the vertical dimension of occlusion and for selecting a preparation technique, type of prosthetic restoration, type of ceramic, and method of cementation.

Considering a Papilla Regeneration Technique | Closing a Diastema with Direct Composite
By David J. Clark, DDS

Many esthetic procedures we routinely provide can improve the tooth's structural integrity and facilitate better health of the surrounding gingiva. Diastema closure, at least in the anterior sextant, rarely gives either of these secondary benefits. Unfortunately, the esthetic diastema closure often results in significant compromises in the root/crown architecture and increased plaque retention with subsequent deterioration in periodontal health and poor ďpinkĒ esthetics.

The Successful Esthetic Rehabilitation Through Simulations
By Dr. Jeff Trembley

The most critical factor to communicate to the laboratory for managing control over an esthetic rehabilitation case is the dentofacial smile design. Imagine the predictable restorative success we all could attain in the esthetic zone if we provided the laboratory with the tooth arrangement and form; the ratio of tooth width to height; and illustrate how these relationships are perceived against the unique facial properties of each patient. If these metrics are truly what determines successful esthetic cases, then the burden to communicate those relationships to the ceramist would lie with the practitioner, without error.

Excessive Gingival Display Managed with Lip Repositioning, Esthetic Crown Lengthening, and Veneers
By Kenneth Valladares, DDS, CDT, and Paula Vargas, DDS, MBA

Excessive gingival display, also referred to as gummy smile, can be managed by a variety of treatment modalities, depending on the etiology. Mild and moderate gummy smiles can be successfully treated by periodontal plastic surgery. However, for excessive gingival display as in vertical maxillary excess (VME) II or III cases with 5 to 8 mm or more of gingival exposure, this procedure is not enough. Many patients decline the more invasive Le Fort surgery and opt for a less invasive surgical lip-repositioning procedure. Therefore, surgical lip repositioning combined with crown lengthening is suggested as an effective and predictable procedure to reduce gingival display.

A Histo-Anatomic Analysis of Color: Dentin Anatomy and the Principle of Scattering
by Javier Tapia Guadix, DDS

In order to create the most natural-looking restorations, a thorough understanding of the histo-anatomic structures and light interaction of the natural dentition is key. While we generally have a great understanding of the external anatomy of teeth, gaining that same level of understanding of the internal anatomy is still not easy for dental practitioners.

There are several techniques that allow us to analyze the relationship between the dentin anatomy and the enamel anatomy. Selective enamel dissolution allows enamel to dissolve in hydrochloric acid, giving us a true vision of the anatomy of the dentin. Becoming familiar with the relationship between convexity and concavity will assist us in creating the most natural-looking restorations.

The Split Centripetal Build-Up Technique for Large Class II Composite Restorations
by Gaetano Paolone, DDS,
Salvatore Scolavino, DDS,
Nitzan Bichacho DMD

There are several layering approaches for Class II restorations. The most commonly used are horizontal layering (HL) and the centripetal build-up technique (CBT).¬ The latter is a proven technique that, in order to simplify restorative and modeling procedures, converts a Class II cavity design to a Class I through the application of a thin composite interproximal wall. The CBT defines the perimeter of the restoration and, once it is completed, the clinician has the advantage of a Class I cavity design.

This short video presents a modified version (split CBT) for medium-to-large Class II cavities in which multiple thicker, separated interproximal increments are used to reduce the number of adhesive surfaces, minimize the shrinkage issues of resin-based restorative materials, and provide proper anatomical information for occlusal modeling.

Study & Practice: A Visual Essay on Pink Ceramics
By Jungo Endo, RDT

Creating lifelike restorations and gingiva requires a great deal of knowledge about tooth and gingiva morphology and color. It is necessary to study the different layers and structure of natural teeth and soft tissue and practice replicating them to achieve precise results.¬ Studying the forms and color of natural teeth and soft tissue will help all patients, including the many who have suffered trauma to the teeth and gingiva.

Patients who have suffered from trauma have been dealing with emotional and sometimes physical pain for years, with loss of bone and gingiva. The patient featured in this visual essay was unhappy with her existing restoration. The color of the restored gingiva did not match her natural soft tissue color. By harmonizing the pink and the white with her natural color, natural-looking and beautiful restorations were created.¬ Today's¬ patients have high esthetic demands, which requires us to push the envelope in creating periodontal tissues and teeth.

Gonçalo Bártolo Caramês, DDS, MSc
Ronaldo Hirata, DDS, MSc, PhD
João Caramês, DDS, PhD
A. Alper Comut, DMD, DMSc

The noninvasive trial restoration (NTR) serves as a diagnostic and communication tool that allows 3D information to be transferred from the diagnostic wax-up to the patient's mouth. If esthetic alterations are required or requested by the patient, the silicone index can be poured and the alterations produced over a new model, saving the original diagnostic wax-up design. Together with clinical photographic documentation, pouring the NTR index improves patient-clinician-laboratory communication, because a 3D record representing the evolution of the esthetic design is saved and can be revisited at any time during the treatment.

The incorporation of noninvasive trial restorations is a desirable step for elective restorative treatments. Achieving a high level of accuracy and precision should be a goal of all the steps, including those involved in fabrication of the NTRs themselves, as they will provide information when decisions are made regarding possible invasive adjunctive treatments.
