The purpose of this study was to evaluate the failure rates of porcelain laminate veneers (PLVs) and the influence of clinical parameters on these rates in a retrospective survey of up to 12 years. Five hundred eighty laminate veneers were bonded in 66 patients. The following parameters were analyzed: type of preparation (depth and margin), crown(More)
The Class III defect environment entails a vertical and horizontal deficiency in the edentulous ridge. Often, bone and soft tissue surgical procedures fall short of achieving a natural esthetic result. Alternative surgical and restorative protocols for these types of prosthetic gingival restorations are presented in this three-part series, which highlights(More)
This second article in a three-part series on the use of artificial gingiva in fixed partial restorations focuses on diagnosis and treatment planning. Often, traditional treatment of complicated situations can result in a definitive restoration that is less than esthetic. With appropriate planning that incorporates thorough clinical examinations,(More)
Part 1 of the present series presented a rationale for including prosthetic gingiva in the planning of a fixed restoration to ensure an esthetic result for patients with severe horizontal and vertical ridge deficiencies. The second part focused on the diagnostic and treatment planning aspects of the use of artificial gingiva. This third and final(More)
This article evaluates the long-term clinical performance of porcelain laminate veneers bonded to teeth prepared with the use of an additive mock-up and aesthetic pre-evaluative temporary (APT) technique over a 12-year period. Sixty-six patients were restored with 580 porcelain laminate veneers. The technique, used for diagnosis, esthetic design, tooth(More)
Various types of dental preparations for laminate veneers have been proposed,depending on factors such as the properties of the ceramic material, remaining dental structure color, need for altering the dental contour, laboratory fabrication technique, and occlusal relationships. Clinical observations of successes and failures associated with the development(More)
The objective of this narrative overview is to discuss several in vitro and in vivo studies regarding the performance of one-piece zirconia implants in combination with the description of two clinical scenarios where zirconia implant prototypes were utilized with emphasis on the possible scientific and clinical concerns that may affect the functional,(More)
Harmony among the teeth, lips, and facial components is the goal of prosthodontic treatment, whether performed by conventional or digital workflow methods. This clinical report describes a facial approach to planning computer-guided surgery and immediate computer-aided designed and computer-aided manufactured (CAD-CAM) interim complete-arch fixed dental(More)
Medical and dental histories, clinical examination, study models, and photographs provide the data for a proper diagnosis and the treatment plan for esthetic dentistry. However, they do not offer all the information necessary to analyze the smile and create harmony with the lips and face without excessive intraoral adjustments. Dentolabial parameters vary(More)
