[Split crest to enlarge horizontal dimension of alveolar ridge. an overview of techniques and case demonstration].

Restoration of the edentulous alveolar ridge with dental implants often requires the ridge width to be augmented in order to allow its placement. Technique of splitting the alveolar ridge aimed to enlarge its horizontal dimension is achieved by using different osseous surgical tools to allow simultaneous or staged placement of dental implants. Treatment of the thin alveolar ridge can be carried out predictably using ridge expansion technique. Good esthetic and functional outcomes can be achieved predictably as long as the surgical principles and protocols are followed carefully. A short literature overview of split crest techniques and a case presentation is included in this article.
