I technique _ first part of an implant treatment _Introduction Faced by a missing lateral incisor, practitioners often consider a wide range of issues and are also faced by numerous treatment options: _in a young patient, faced with a unilateral or bilat- eral agenesis, he has to choose between an ortho- dontic treatment that either opens up the spaces or closes them. This decision, when taken early in the overall treatment, will affect both the patient and their caregiver for a long time (Fig. 1); _in an adult patient, this is a consequence of bone, physiological, traumatic or infectious resorption, whichwillresultinadecisionwhetherornottorec- ommend a bone reconstruction or a gingival aug- mentation. In every situation, the results will be judged by the patient and those around him. Since the lateral max- illary incisor is an integral part of the smile, aesthetic expectationsaregenerallyveryhighand,iftheresults donotmeettheexpectations,disappointmentcanbe powerfully felt. When describing the different treatment stages, anumberofpitfallsanddifficultieswillbehighlighted and advice and clinical protocols will be given, in or- der to ensure that the results of this implant/pros- thetic treatment are predictable and as aesthetically attractive as possible. This first article is concerned withtheseissuesasregardsthepreprostheticstages; the second will consider the most important aspects oftheprostheticstagesaswellasaestheticoutcomes and their evolution over the long term.
