[Analysis of enamel thickness of anterior teeth and its relation to preparation for porcelain veneers].

The development of porcelain, acrylic and mixed crowns is not under discussion. In the same way, it should not be discussed now the evolution of silicate cements, the acrylics, the glass ionomer and the composite resins in their different techniques. We only want to analyze concisely the actual condition of the investigation and of the clinic, as regards the reconstruction with lamellas of the front part of the mouth. Lit can be deduce from the researches that the measurement of the vestibular thickness of y the enamel upon the incisives, laterals and canines specifies that: 1. As regards form, the most suitable elements for the laying of the porcelain laminate are the square, then the ovoid and finally the triangular ones. 2. The central incisives are the best; secondly the canines and then the laterals (this is directly related to the convexity of the fronts and to the amount of residual enamel). 3. It is advisable to finish the peripheric edge of the cavity 1 mm, above the anatomic neck to assure an adequate thickness of enamel in order to obtain a good adherence of the porcelain laminate veneers. 4. It is convenient to use appropriate techniques during the adamantine preparation in order to control its depth (for example diamond-like stones with ends).

[Study of traction and effect of bonding agents on etched porcelain].

Nowadays many authors suggest the use of porcelain laminate veneer that has come to play an important role in the solution of many esthetic and functional problems. At the moment, it is the alternative treatment to solve some cases with the least dental reduction, the highest fitting and a low cost. To evaluate the tractional resistance done on the porcelain veneer, in which acid etching and connecting agents were applied, I suggest: 1. The resistance of traction carried out on etched porcelain laminate to which an agent of silane join and a resin of connection were applied, was the one that had the best conduct. 2. The tractional resistance carried out on the laminate fronts where a treatment of only silane and resin of connection was applied, was greater where the treatment of silane was employed. 3. The etched with acid both in the adamantine surface and in that of well depurated porcelain, is an important factor to obtain a good retention.

[Different types of tooth preparation for placement of ceramic veneers].

Lately the porcelain laminate veneer in the fore-upper sector of the mouth, has gained popularity due to the multiple advantages that it has shown, therefrom the purpose of describing the different reduction techniques according to the function of the laminate restauration. We describe the instruments that will be used and the sequence that should be carried on during the different types of reduction, classifying them in three large groups according to the anomaly presented by the elements to be restored.

[Porcelain veneers: 4 application technics].

The present paper describes the different techniques currently employed for the use of porcelain laminate veneer, from the simplest stock teeth to the most complex casting system. Advantages and disadvantages of each are described herein.

[Ceramometal rehabilitation on gnathological principles].

We suggest a technique in which the rules of the Gnatology are strictly followed and an organic occlusion is entirely made of metal, it is checked its function, appropriate alignment, phonation, aesthetics, gingival adaptation, contact, relations, etc., as if it were a final rehabilitation. Then, on the original model, each crown, future ceramic carrier, is made and the necessary space for the porcelain and its adaptation is tested into the mouth. In the same way, the following steps are carried out till the biscuit and all the relations with the elements, that are to be imitated, are strictly established, when the biscuit has been finished, the whole is tested into the mouth. Finally, the crowns and bridges are made up and shade but this will not alter the function that has been obtained, due to the meticulous technique that has been suggested.

[Acid etching of prefabricated porcelain veneers].

The aim of the present work is to study on standard porcelain teeth the acid concentration to produce the micromechanic retention with the cemented resin and then to enamel. Teeth were beater-up following the described technique, the application of two different types of etch solutions: hydrochloric acid and fluorhidric acid, in a lack of application time between 10 to 20 minutes. With the purpose of determine the type of etch solution that produce the best amount of micropores in standed porcelain laminates veneers we can conclude that: to the internal etched of the standard porcelain laminates veneer, the utilization of fluorhidric acid is the most convenient, also is necessary the previons stand blaster with aluminum oxide of 25 um to increase the retentive capacity over the etch surface.
