Mario Imburgia, Angelo Canale, Davide Cortellini, Marco Maneschi, Claudio Martucci, Marco Valenti
The esthetic treatment of anterior teeth has always presented a challenge in clinical practice. With the improvement of dental materials, many restorative options such as composite resins, all-ceramic crowns, and ceramic veneers have become available. The current challenge in reconstructive dentistry is to obtain excellent esthetic results while preserving the biological structures involved as much as possible. Thanks to the introduction of high-strength etchable dental ceramics, clinicians and technicians have materials and procedures at their disposal that allow them to restore esthetics and function through a minimally invasive approach...

Purpose. Recently, the request of patients is changed in terms of not only esthetic but also previsualization therapy planning. The aim of this study is to evaluate a new 3D-CAD-CAM digital planning technique that uses a total digital smile process. Materials and Methods. Study participants included 28 adult dental patients, aged 19 to 53 years, with no oral, periodontal, or systemic diseases. For each patient, 3 intra- and extraoral pictures and intraoral digital impressions were taken. The digital images improved from the 2D Digital Smile System software and the scanner stereolithographic (STL) file was matched into the 3D-Digital Smile System to obtain a virtual previsualization of teeth and smile design...

BACKGROUND: When treating children, a conservative and minimally invasive approach is mandatory. In dental traumas with partial coronal destruction, veneers represent the fastest and most effective method to rehabilitate front teeth of a young patient, since these no- or minimal-preparation restorations were proved to have predictable results without reducing the enamel layer. Indirect additive anterior composite restorations, besides being quick and minimally invasive, have to be considered a good treatment option for rehabilitating children, because they are inexpensive and repairable over time...

The target restoration space (TRS) is a required tooth space that should be occupied by an esthetically formed and optimally functioned crown, veneer, or other fixed restoration. It can be either internal of or external of a tooth. Since minimal invasive can't be achieved without a minimal TRS, a precise preparation of slightest damage should conform to the transfer guide based on TRS. This paper introduces the concept, design of TRS, explains how it can be applied in tooth preparation, and helps to better understand a precise and minimal invasive tooth preparation technique...

The standards of dentistry are being elevated, with a greater emphasis being placed on esthetics along with functionality. Minimally invasive dentistry has become an essential component in creating restorations that are functional and have increased longevity. In the case discussed in this article, the patient underwent 9 months of orthodontic therapy to correct her improper overbite and overjet, and the spacing of her dentition so the teeth could be positioned for future minimally invasive restorations. Orthodontic therapy was paramount in positioning the teeth so that the future restorations would have ideal axial inclinations and be as minimally invasive as possible...

STATEMENT OF PROBLEM: In some clinical conditions minimally invasive complete crown tooth preparations are indicated. This is especially true when gross removal of tooth structure would weaken the remaining tooth or violate the vitality of the dental pulp. OBJECTIVE: The purpose of this study was to investigate the influence of (1) exposed lingual zirconia with veneered zirconia crowns, and (2) reduced lingual thickness of monolithic lithium disilicate crowns on the fracture resistance of the crowns after cyclic loading...

No- or minimal-preparation veneers associated with enamel preservation offer predictable results in esthetic dentistry; indirect additive anterior composite restorations represent a quick, minimally invasive, inexpensive, and repairable option for a smile enhancement treatment plan. Current laboratory techniques associated with a strict clinical protocol satisfy patients' restorative and esthetic needs. The case report presented describes minimal invasive treatment of four upper incisors with laminate nanohybrid resin composite veneers...

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 of techniques and materials have allowed some safe parameters to be delineated for effectively performing dental preparations for ceramic veneers or even placing veneers without any preparation...

OBJECTIVE: Severely fluorosed and heavily discolored teeth that have large enamel defects give rise to esthetic concerns and require permanent treatment. In such cases, restorative techniques such as porcelain or composite laminate veneers or crowns are generally preferred, in which tooth preparation is inevitably required. MATERIALS AND METHODS: This clinical report describes a patient with severely fluorosed teeth who was successfully treated with a minimally invasive technique including enamel microabrasion (6...

This case report describes a minimally invasive step-by-step approach to treat a patient with amelogenesis imperfecta. This is a genetic developmental disorder of the dental enamel, which clinically manifests as white and dark discolorations of the teeth. The clinical examination did not reveal the true depth of the staining. Therefore, a step-wise treatment approach was chosen. The first step consisted of a home bleaching procedure, which led to a slight improvement of the esthetic appearance, but the stains were still clearly visible...

UNLABELLED: In case of severe dental erosion, the maxillary anterior teeth are often particularly affected. Restoring such teeth conventionally (ie, crowns) would frequently involve elective endodontic therapy and major additional loss of tooth structure. A novel, minimally invasive approach to restore eroded teeth has been developed and is currently being tested in the form of a prospective clinical trial, termed The Geneva Erosion Study. To avoid crowns, two separate veneers with different paths of insertion have been used to restore the affected anterior maxillary teeth, regardless of clinical crown length and amount of remaining enamel...

STATEMENT OF PROBLEM: Preparation designs and ceramic thicknesses are key factors for the long-term success of minimally invasive premolar partial coverage restorations. However, only limited information is presently available on this topic. PURPOSE: The purpose of this in vitro study was to evaluate the fracture resistance and failure modes of ceramic premolar partial coverage restorations with different preparation designs and ceramic thicknesses. MATERIAL AND METHODS: Caries-free human premolars (n=144) were divided into 9 groups...

In a historical pendulum of porcelain veneer preparation concepts, an oversimplified version of the so-called "no prep" approaches has resurfaced. A case from the USC student clinics is presented, which could be easily considered by many as a "no prep" veneer case. Moderate tooth preparations guided by natural morphology were used instead with a great benefit on the final outcome. While it is widely accepted that minimally invasive restorative approaches should be favored, a certain controversy exists regarding strictly noninvasive approaches...

OBJECTIVES: Adhesive resin composite technology enables dentists to add composite material to tooth surfaces to close gaps and reshape tooth form without cavity preparation. This option creates new possibilities for minimally invasive dentistry as the tooth shape, position and colour can be altered without loss of tooth substance. However, evidence-based data on direct composite buildups are rare. METHODS: The purpose of this study was to evaluate the outcome and to document the occurrence of unfavourable events and clinical findings of 176 direct composite buildups that had been performed in the Department of Conservative Dentistry, University Hospital Heidelberg, Germany, between 2002 and 2008...

A new type of material consisting of a ceramic substructure infiltrated with a composite material--referred to as a hybrid ceramic--is currently being introduced for dental CAD/CAM use. The characteristic brittleness of ceramic is thus replaced by an elasticity resembling that of natural human dentin. The material features a high fracture load value of 2980 N, and is straightforward to process in CAD/CAM milling machines. This article presents a case example describing the manufacture of a veneer restoration...

AIM: The present case report described the use of contact lens of thin porcelain veneers as a restorative therapy to solve anterior teeth disharmony. BACKGROUND: Fragments of thin veneers are minimally invasive restorations with little or no dental preparation and present thickness ranging from 0.2 to 0.5 mm. They are used in case of diastema closure, small changes of teeth, color and restoration of teeth with small fractures. CASE REPORT: A 25-year-old man was admitted at a dental clinic complaining about the diastema presence on the upper anterior teeth...

Porcelain laminate veneer restorations are much thinner than other types of restorations such as crowns or onlays. Within the range of 0.3 to 1.5 mm, it is not an easy task for the clinician to provide the appropriate clearance for the ideal restoration and, concurrently, for the dental technician to predictably create a piece of imitated nature. The advantages of enamel preservation and the principle of nil nocere imply removing as little tooth structure as possible for the purpose of maintaining tooth health, its mechanical strength and ensure the treatment's long-term predictability...
