Abstract:

BACKGROUND
The indirect inlay technique, within Dentistry, is a restorative technique that allows us to control the anatomy, occlusal characteristics color and optical effects of the teeth. Since the posterior zone requires a correct articulation and good adjustments on marginal zones in our daily practice, it is important for postgraduate students to be able to learn a technique that helps us to secure predictable and appraisable results.

OBJECTIVES
1. - To be able to realize a preclinical learning of a technique for indirect inlay with composite resins on posterior teeth to apply it over the patient later.

2. - To be able to evaluate all the students with the same objective parameters previously established.

MATERIAL AND METHOD
Over a typodont and with a hemiarch mounted with all teeth, every student will take an impression with silicone and make a model with stucco. Next the teacher will perform a cavity over a molar with the characteristics for an inlay with compound resin. All students will take a new impression with silicone of that model and again make a new model of stucco. Over the new model all the students will perform an indirect inlay of compound resin. The students will use the incremental technique and will have to reproduce all the anatomic details of the affected surfaces of the tooth. Once polymerized, the resin will be extracted from the model and will be inserted on typodont to check all the adjustments and evaluate it.
The previous model of stucco helps us as a reference to realize the occlusal anatomy of the tooth. All students will have the same model of reference and will be able to realize this technique as many times as necessary to learn it to apply it clinically.
The parameters: Anatomy, adjustments of contact points, adjustments of gingival margins, polish, color, and occlusal anatomy details will be evaluated.

RESULTS AND CONCLUSIONS
It is important in Restorative Dentistry to know and to practice with the material that we have in the dental office to realize an indirect inlay technique according to the structure and the physical properties that allow us to reproduce the own characteristics of the natural teeth.
This technique allows realizing the tooth in a reproducible form for all postgraduate students, so many times as necessary, and in addition it serves to establish an objective evaluation model in Dental Education.
