The objective of the present article was to review the literature concerning the use of dental implants during the last decades. It is based on the excellent paper published by Dr. Roland Meffert in the Proceedings of the World Workshop in Clinical Periodontics of 1989. The following points were analyzed: 1) The current criteria of success for dental implants. 2) The histology of the perimucosal or transgingival area surrounding the dental implants. 3) The means of retention of the different types of dental implants. 4) Four basic forms of dental implants: a) Blade-Vent implants, b) Transosteal Implants, c) Osseointegrated Implants, and d) Subperiosteal Implants. 5) The steps for the construction of an osseointegrated prosthesis. 6) The maintenance of the case. 7) Indications and contraindications of the different types of implants. 8) Conclusions. 9) Bibliography.

The election of a investigation about craniofacial growing and development in Mexican children, was done due to a lack of national information in this rubric and as a fundamental part of the "growing and development in the scholastic" module of the Universidad Autónoma Metropolitana-Xochimilco, which work hypothesis was that "craniofacial growing and development in Mexican, 6 to 12 children in Xochimilco area are due to nutritional deficiency, second dentition eruption delay and dental maloclution "which was totality confirmed in a 100 Mexican facial characteristic children field work study, with cephalometric studies which permit to determine the craniofacial growing standard. This study was corroborated with a 40 children, 4 years later follow up.

Describing the technique for laying the implants in osseous defects or with esthetic purpose in anterior upper tooth. In this article we describe only the anterior tooth technique. Also the surgical procedure can be used in posterior area. In this technique the healing process occurred by primary intention, in case of graft have been use, this can not be exfoliative. The gingivals craters can not be developed, which is very common in periodontal flap, and this will be more comfortable for the patient to maintain better oral hygiene.

To our Knowledge, this is the first work in a number population (higher than 500 sample WHO) that is carried out in our country about lesions in the Oral Mucosa. The advantages in this Kind of studies are recognized particularly in the fields of academic, research and services. This work presents the first view of a permanent research project of Oral Mucosa Lesions at the admission clinic, School of Dentistry, Universidad del Bajío. The findings are from the evaluation of 7,297 patients, 15 years or older, that seek dental services between January 1982 and June 1989 (7.5 years). The lack of national data and the oldest population samples in other countries studies stopped wider evaluations, even though the study purpose was not affected, it was possible to offer qualitative data in the respect of prevalecence, variety and etiopathogenesis of those type of pathosis in the Oral Mucosa. The general prevalecence in the group was approximately 13%, identifying lesions more frequently in males, but higher variety in females. Report on 40 different entities, presented in general according to a descent order of prevalencece and reagrouped by sex and pathology. In half the lesions was possible to identify as the cause, acute and cronic traumatic agents; The infectious associations were also very frequent. Those last observations are of high relevance concerning the prevention of Oral Mucosa lesions.

The most important change in restaurative Dentistry, since the foundation of the Atneo Odontológico Mexicano, has been the popularity of the use of porcelain fused to metal restorations. The technique that is carried on with success is still the best choice, it is may times by technicians and Dentists altered in such a way that the final result is poorer than the things we use to do long time ago. The main problems in the technique are reviewed in this article.

As all we know in the most of schools do not teach color knowledges, neither the way to take it in dental office. This article attempt to help to student, dentist and ceramist to understand color, its origin, metamerism phenomenon, dimensions or cualities; so we can refer about color and communicate in proper way. Also we order concepts as rules that they can be useful for helping to resolve this complex problem.

The epidemiological characterization of the occlusion was made on basis of the classical Angle Classification through a statistical selection from a total of 4363 females and males children; which ages ranged between 7 to 14 years old. These were students registered in public federal schools located in the south of the metropolitan area. The results of the study were determined as follows: Class I, 84.7%; Class II, 10.9%, Class III 4.3%.

The bleaching of non vital teeth that is described in this article has demonstrated to give good clinical results, and because of its easy way to apply we believe that it is the option for the treatment of this teeth, as long as we have a good an realistic diagnostic considering the results we may obtain. One the selection has been made we proceed to the bleaching, the substances that we use are easily obtain, superoxol and sodium perborate. The preparation of the tooth began with the removal of any restauration or decayed tissue that is may present after this we remove the material from the pulp chamber 1 mm below the gingival margin, then clean perfectly the chamber, then we deshidrate the tubulae, then put a pellet of cotton on the vestibular wall of the chamber, put some superoxol in the cotton, heat it up, remove the cotton, put some sodium perborate and hidroge peroxide paste in the chamber and seal it with cavit, and wait from 3 to 7 days for results.

Description of a technique that allows the copy of the finishing line even when this line es deep in to the sulcus and without the need of gingival retraction which is very painful, bleeds easily and is limited to few teeth. The impression technique with acrylic tubes allows the operator to duplicate models if it is so desired, at the same time full arch impressions with multiple preparations can be taken in one attempt.

This monograph is focused on the role the study group (as an instrument for professional improvement) has played in the development of Mexican Odontology. Today, it still is the most factible alternative for the one who does not wish to be relegated with regards to odontological innovations. Since the first professional societies emerged last century, they had the nature of study groups. And although their aspirations were nationwide, they gave the profession one of the most valuable means of information to the dentist of that time: the scientific magazine. From these societies (study groups) the idea of forming the first Dental School in the Mexican Republic in 1904 originated and crystallized. In the 1930's, societies of specialties appeared in the Mexican Republic working from that moment on as study groups. They are responsible for directing scientific information to the dental population in general, even stepping out of the subject-matter pertaining to their own area. These Associations were: Orthodontics and Buccal Surgery. In 1945, the Dental Study Group U.S.C. of Mexico appeared as a formal study group. Since then, this group offers the dental profession a seminar that is the second oldest Dental Seminar worldwide. One of the merits of the group was to initiate this type of education which spread throughout the Mexican Republic giving rise to the formation of new study groups. In 1966, the Ateneo Odontológico Mexicano was created, and the mystic of its formation, politics and performance are described in this monograph.
