The Functional and Esthetic Deficit Repiaced with an Acrylic Resin Gingival Veneer Esthetic Dentistry The functional and esthetic deficit repiaced with an acrylic resin gingival veneer Trakol Mekayarajjananonth, DDS, MS.

DDS" Periodontal attachment loss in the maxillary anterior region can often lead to esthetic and functional clinical problems including disproporiional and elongated clinical crowns, visible interdental embrasures, and altered linguoalveolar-labiodental consonant production. Assuming fixed prosthetic reconstructions will be chosen to treat these areas, it becomes a hygienic compromise to fill these areas in with porcelain. In the presence of these problems, an acrylic resin gingival veneer is an easily constructed, inexpensive, and practical device fo optimize the esthetic and functional outcome in these special situatons while permitting cleansibiiity of the prosthesis and supporting tissues.

  • Using the Erbium Laser to Remove Porcelain Veneers in 60 Seconds Minimally Invasive, Efficient, and Safe Glenn A
    SCIENTIFIC SESSION SEATTLE 2013 Using the Erbium Laser to Remove Porcelain Veneers in 60 Seconds Minimally Invasive, Efficient, and Safe Glenn A. van As, DMD Dr. van As will be speaking at the 29th Annual AACD Scientific Session in Seattle, Washington, on April 26, 2013. The title of his lecture is “You Light up My Life: Lasers in Contemporary Esthetic and Implant Dentistry.” In this article, Dr. van As discusses how erbium lasers have the ability to quickly and safely remove all porcelain restorations. Abstract For more than 30 years, porcelain veneers have provided clinicians with a method for changing a patient’s smile almost instantaneously. At times, however, veneers require replacement due to caries, fractures, or leakage or simply because the patient is unhappy with the esthetic outcome. Erbium hard tissue lasers can be used to efficiently, safely, and predictably remove all porcelain restorations while also keeping them in one piece. In doing so, this new tool for removing porcelain restorations provides clinicians with an alternative to high-speed handpieces while preventing further iatrogenic damage to underlying tooth structure.

  • The Cosmetic Challenge of the Class 2 Division 2 Patient
    The Cosmetic Challenge of the Class 2 Division 2 Patient Rick DePaul, Jr., DDS Author, Powerprox Six Month Braces Technique The class 2 division 2 malocclusion can be a difficult one to achieve a great cosmetic result on. One characteristic of this malocclu- sion is retroclined upper central incisors. These teeth are also supererupted leading to a deep bite and less than desirable gingival architecture. The lateral incisors are often labially displaced as well (Fig. 1). All of these factors make for a very challenging cosmetic case. Many patients want quick results. This is one of the great bene- fits of placing porcelain veneers. You can get a great smile very quickly. Unfortunately, you cannot simply place veneers on the teeth in a division 2 case and get a great result. In order to improve the gingival architecture significant crown lengthening must be per- formed prior to placing veneers. Many times intentional endodon- tics must be performed as well due to the labial-lingual discrepan- Figure 1 cies of the upper incisors (Fig. 2).

My preferred method to treat division 2 malocclusion. these cases is the Powerprox Six Month Braces™ technique. This method allows you to quickly and conservatively treat these difficult cases. Some of the advantages of performing orthodontics instead of porcelain veneers alone on division 2 cases are: • Orthodontics opens the bite. • Less need for crown lengthening since you can greatly improve the gingival architecture with orthodontics.

A smile makeover using porcelain veneers is a com- monly requested cosmetic dental procedure and for good reason. Veneers can be used to correct a myriad of cosmetic dental problems such as discolored, chipped, worn, crooked or spaced teeth. Porcelain veneers, sometimes called porcelain laminates, are thin layers of dental porcelain used to replicate the natural look of healthy teeth. They are used to cover the front and sometimes side surfaces of teeth im- proving their appearance and function. Their strength and resilience are comparable to natural tooth enamel and is the material of choice for smile makeovers. Porcelain veneers resist stains and can be made to www.SmileArkansas.com • 501.819.8071 2 When bonded or adhered to natural teeth, porcelain veneers can create an amazing smile transformation. Smile makeovers using porcelain veneers have become a collaborative process involving input from the patient, treating cosmetic dentist and dental technician. For the best results the cosmetic dentist will discover the pa- tient’s expectations and involve the patient in planning for their smile makeover. Porcelain Veneers are fabricated by a dental technician 10 porcelain veneers were used under the direction of to achieve an incredible smile the treating cosmetic dentist.

  • Minimal Preparation Veneer Case Selection Process
    MINIMAL PREPARATION VENEER CASE SELECTION PROCESS Fondriest J, Roberts M. Prepless Veneer Case Selection. Inside Dentistry. March 2010; 6: 36‐43. by James Fondriest, DDS; Matt Roberts, CDT No- or minimal-preparation veneers offer both benefits and limitations. No synthetic restorative material used to reproduce natural tooth structure can match the combination of ideal qualities of functional strength and optical or esthetic display that exists in nature. Maintaining as much natural tooth structure as possible is a goal when doing restorative dentistry, especially when done for elective purposes. While less tooth reduction is a desirable goal, there are times when more reduction better serves the overall restorative agenda. Evaluation Process for Minimum Preparation Veneer Candidates It is critical to carefully appraise the patient’s pre-existing condition, tooth position, and dentition color as well as Figure 1. This patient’s goals were to straighten functional envelope, phonetic components, and the patient’s his smile, close diastemas, and to make his teeth perceived goals of treatment before deciding the possible show more in his smile. There was interest in modalities of treatment.

Abstract The purpose of this comprehensive review was to evaluate and identify the performance of composite/ceramic onlays versus crowns. The strength of the evidence is based on published trials, systematic reviews and observational studies. Methods: The dental literature was reviewed for controlled clinical studies and retrospective cross-sectional studies from 1966 to 2013. Longevity of onlay or crown is dependent upon many different factors, including material, patient-and dentist-related. Principal reasons for failure were secondary caries fractures, marginal deficiencies, wear and postoperative sensitivity. Minimally invasive dentistry, in cases in which it is appropriate, is a concept that preserves dentition, supports structures and involves low cost therapy.

For the purpose of diastema restoration, a prefabricated sectional veneer provides the same benefits of a traditional ceramic sectional veneer (highly esthetic restoration with no need for tooth preparation) but involves a less technically demanding and time-consuming clinical procedure and a less delicate restoration with a reduced risk of accidental breakage and post-bonding crack formation. The technique presented in this case report bridges the gap between a direct and indirect technique for diastema restoration and introduces a new treatment option to close anterior spacing with a highly esthetic sectional veneer in a predictable and timely manner. Keywords: diastema; restoration; sectional veneer; ceramic veneer; composite veneer; prefabricated veneer 1. Introduction Thanks to the combination of excellent esthetic outcomes and no sacrifices related to healthy tooth structure, orthodontic treatment is frequently advocated to close anterior diastemas [1–3]. However, when a Bolton discrepancy is detected, orthodontic treatment alone cannot establish proximal contacts with proper vertical and horizontal overlaps and restorative treatment is indicated to close the residual spaces [4–6].

    Prospective Clinical Study of Press-Ceramic Overlap and Full Veneer Restorations: 7-Year Results Petra C. Guess, Dr Med Dent, PhDa/Christian F. Selz, Dr Med Dentb/Apostolos Voulgarakis, DDSb/ Susanne Stampf, Dr Rer Natc/Christian F.J. Stappert, MS, DDS, PhD, Dr Med Dent Habild The aim of this prospective clinical study was to investigate the long-term performance of all-ceramic veneers with overlap (OV) and full veneer (FV) preparation designs. Twenty-five patients were restored using 42 OV restorations (incisal/palatal butt-joint margin) and 24 FV restorations (palatal rounded shoulder margin). All restorations were leucite-reinforced glass-ceramic anterior veneers. The 7-year Kaplan-Meier survival rate was 100% for FV restorations and 97.6% for OV restorations. The all-ceramic veneers revealed significant deterioration over time according to United States Public Health Service criteria, irrespective of the preparation design. Based on the 7-year results of this study, both preparation designs can be considered reliable treatment options for anterior teeth with extended deficits.
