INTRODUCTION All-ceramic crowns may not be suitable for discoloured teeth or teeth with enamel defects, teeth with bilateral or unilateral decay. Tooth preparation is one of the important aspects ... are less brittle and therefore less likely to crack, or chip, than all-ceramic indirect fillings; they absorb the shock of chewing more like natural teeth, and more like resin or gold fillings, than do ceramic fillings; and at the same time more resistant to wear than all-resin indirect fillings. The supragingival position of the cervical margin preserves the marginal periodontium, facilitates impression taking and maintains the solid substance of the remaining tooth. The cavity preparation of a glass ionomer filling is the same as a composite resin. To be successful, an all-ceramic crown should have a relatively-even thickness circumferentially. Bonding Agent: The bonding material constitutes the critical interface between the restoration and the prepared tooth.21 In addition to its adhesive properties, its modulus of elasticity is important as it must be able to absorb pressure, just as the dentin enamel junction (DEJ) does.22 The interface includes all prepared surfaces. However, there is the risk of unwanted overcontour. Bernhart J, Bräuning A, Altenburger MJ, Wrbas KT. J Prosthet Dent 2002;87:503-509. This monolithic, ceramic adhesive restoration requires specific preparation techniques to satisfy criteria that are primarily biomechanical in nature: a cervical margin in the form of a butt joint and a preparation of the pulp chamber that does not extend into the root canals. DefinitionDefinition • Non metallic full coverage ceramic restoration . Slangen P, Corn S, Fages M, Cuisinier FJ. Glass-ceramic: Glass-ceramic has the advantages of biocompatibility and biomimicry,15 and its wear coefficient is close to that of the natural tooth.16 In addition, the single interface of a 1-piece restoration enhances cohesion. This simple and efficient concept is compatible with the philosophy of biointegrated prostheses. Messer RL, Lockwood PE, Wataha JC, Lewis JB, Norris S, Bouillaguet S.

The main objective is to dispense with metal and achieve an all-ceramic bonded reconstruction that is minimally invasive of root canals, as the use of root canals for anchoring has been cited as an important factor in weakening the tooth.8-11 Thus, the preparation for endocrowns is different from that for conventional complete crowns.12,13, The endocrown is described as a monolithic (one-piece) ceramic bonded construction14-18 characterized by a supra-cervical19 butt joint, retaining maximum enamel to improve adhesion. From a biomechanical standpoint, the restoration allows adaptation to strains at the bonded joint. Adhesives such as self-adhesive RelyX Unicem (3M, St. Paul, Minn.) or composites such as Multilink (Ivoclar, Schaan, Liechtenstein) are used for bonding the endocrown to the prepared tooth (Fig. Zaslansky P, Friesem AA, Weiner S.

Various studies suggested extending the concept to maxillary premolars6 and maxillary incisors,7 but these proposals remain controversial. A pressed endocrown, with sprue attached, positioned on a master mold (b). Mrazek WR. Its shape allows control of the orientation of the reduction and ensures a flat surface, which determines the position of the cervical margin or “cervical sidewalk.” The cervical margin should be supragingival; however, if clinical factors or esthetics require, the margin can follow the gingival margin. Root canals are not involved in the process, and the procedure is less traumatic than alternatives. Unfortunately, till now, few studies were conducted to understand three-dimensional morphology of Chinese teeth, … They concluded that endocrowns were more resistant to compressive forces than conventional crowns. Laboratory procedures for fabricating pressable all-ceramic restorations. The alternative to an all-ceramic would be a PFM crown, which has a longer track record of providing lasting, durable service. All-Ceramic Crown Prep – Bur Set (6 burs) $ 49.00 $ 45.00.
