The purpose of this research is to perform and verify the “modified 50° preparation” suggested by the authors. This procedure was performed with a scrupulous standardization of the tooth’s preparation and then of the laboratory techniques to produce a metal-ceramic crown, and the same for the crown cementation technique of on the preparation of the original sample. After the esthetic evaluations, the obtained sample was included in EPON resin and sectioned in the lingual-vestibular sense. The sections were then observed with an optical microscope in different magnifications for the final evaluations...

Anterior crown fractures are a common form of traumatic dental injuries that mainly affect the maxillary incisors, especially in children and adolescents. Complicated crown fractures although less common, pose a challenge to the clinician. The main objective while treating such cases is successful pain management and immediate restoration of function, esthetics and phonetics. Since the development of the adhesive dentistry, the patient's own fragment can be used to restore the fractured tooth. Reattachment of fractured tooth fragments offers a viable restorative alternative...

Treatment of tooth wear has increased over the last two decades. However, the treatments involved have not been satisfactory to most patients, nor have they achieved the expected goal on some worn teeth. New approaches have emerged to reconstruct full arches in a minimally invasive way that take advantage of developments in the field of adhesive dentistry. These new concepts constitute a revolution in dentistry and their application requires adapted techniques and training. The purpose of this article is to suggest a precise and reproducible method that simplifies the treatment of worn dentition...

Recent years have seen increasing demand for treatments aimed at improving dental esthetics. In this context, both patients and dentists prefer to preserve dental structures as far as possible; thanks to technological advances, especially in adhesive dentistry, new materials and minimally invasive techniques such as "no-prep" (no preparation) veneers have made this possible. Nevertheless, no-prep veneers have specific indications and suffer certain disadvantages. OBJECTIVES: This clinical case describes the rehabilitation of the upper anterior region by means of no-prep veneers, with BOPT (Biologically Oriented Preparation Technique) cervical margins...

Achieving successful long-term esthetic outcomes in implant dentistry requires that the height and width of the facial or buccal alveolar bone wall and, subsequently, the peri-implant tissues be maintained. Partial extraction therapy (PET) can be used to reduce the risk of facio-lingual collapse after tooth loss and improve the preservation of alveolar bone height and blood supply. This article demonstrates the use of PET for treatment of a hopeless tooth in the esthetic zone. After removal of the fractured maxillary central incisor, an implant was placed and restored with excellent esthetic, functional, and periodontal results...

Since the first introduction of the Cerec system (Sirona) in the early 1980s, the use of computer-aided design/computer-aided manufacture (CAD/CAM) technology has spread widely in modern adhesive dentistry. Thanks to this innovative technology, it has been possible to carry out chairside restorations fully managed by the clinician, with the advantages of lower costs for the patient, more rapid execution of the restorations, and the exclusion of the provisional phase. With further improvements in chairside technologies and materials, specifically in the field of composite resin blocks, it is now possible to fabricate multiple ultrathin, minimally invasive or even noninvasive restorations in one single appointment...

Farhad Tabatabaian
Zirconia ceramic is a popular trend in esthetic and restorative dentistry. Computer-aided design/computer-aided manufacturing (CAD/CAM) systems have been well developed to fabricate zirconia frameworks and restorations with acceptable mechanical properties. Zirconia ceramics have excellent optical characteristics; however, achieving optimal esthetic outcomes with zirconia-based restorations is still challenging due to multiple effective factors on the final color. These factors are different layers of a zirconia-based restoration and its underlying structures including: dental substrate, cement, zirconia coping, veneering ceramic, and glaze...

The anatomical form of a tooth can undergo changes leading to loss of tooth form. The loss of tooth surface can be due to varying etiology. Dental caries, attrition, abrasion, erosion, involving any surface of the tooth can lead to loss of tooth structure. The rate of tooth destruction may proceed to such an extent that the esthetics, function and comfort may be lost. The role of a practioner lies in identification and screening of such case and motivate for oral rehabilitation that includes habit cessation...

Reattachment of the tooth fragment is an ultraconservative technique for managing coronal tooth fractures when the tooth fragment is available, and there is minimal violation of the biological width. The advances in adhesive dentistry have allowed dentists to use the patient's own fragment to restore the fractured tooth which provides fast and esthetically pleasing results. This article reports fragment reattachment technique and presents two clinical cases of complicated crown fracture.

The most common discrepancy concerning tooth size is the presence of peg-shaped lateral incisors, which can cause teeth with reduced size, anterior diastema, and consequently an unpleasant smile. The development of the adhesive dentistry and ceramic veneers allowed all ceramic-bonded restorations to become an esthetic and functional approach to reestablish the smile harmony. The purpose of this clinical report is to describe a conservative treatment approach to recover an esthetic disharmony caused by bilateral peg-shaped lateral incisors...

The aim of the study was to assess gender-related preferences in the choice of oral rehabilitation methods. The study involved 225 patients aged 16-75. The analysis included patients survey and the assessment of actual procedures received during one year follow-up. The study revealed women to be more attentive to oral health issues resulting in more regular appointments and better compliance. Dental treatment before planned pregnancy was, however, completed in only half of the patients. When choosing materials and constructions for oral rehabilitation the leading criteria for men were 'quality' and 'safety', while women chose 'esthetics' and 'quality'...

OBJECTIVE: Porcelain fused to zirconia (PFZ) restorations are widely used in prosthetic dentistry. However, their tendency to delaminate along the P/Z interface remains a practical problem so that assessing and improving the interfacial strength are important design aspects. This work examines the effect of modifying the zirconia veneering surface with an in-house felspathic glass on the interfacial fracture resistance of fused P/Z. METHODS: Three material systems are studied: porcelain fused to zirconia (control) and porcelain fused to glass-graded zirconia with and without the presence of a glass interlayer...

Today clinicians have a variety of treatment modalities available to address the increasing number of implant procedures performed each year. Single-stage implant surgery is now commonly used in implant dentistry. With patient demands for immediate restoration, the utilization of 1-piece implants is gaining acceptance. This article reports the results of tapered 1-piece implants (Zimmer Biomet) placed in a single practice over a 10-year period. A total of 33 1-piece dental implants were placed in 24 patients and provisionally restored out of occlusion at the time of surgery...

Due to improvements in esthetic dentistry, the number of patients seeking to obtain a more harmonious smile has increased. A 40-year-old woman was referred for treatment because she was dissatisfied with the effect that diastemas and a conoid tooth had on her smile. Her maxillary anterior teeth were relatively short, resulting in a compromised esthetic relationship between height and width. Orthodontic treatment for better distribution of her teeth was recommended to the patient, but she refused, wanting faster and less expensive treatment...
