Abstract
Background: The collapse of the alveolar ridge in an edentulous area in patients who will undergo oral rehabilitation impedes the harmonic relationship between pontic and ridge. To correct this type of defect there are several surgical techniques that aim to achieve soft tissue augmentation, allowing the conformation of an ideal profile with the use of a pontic. The aim was to demonstrate how the technique of tissue modification in an area with a class b defect of Allen allows the correction of aesthetics in the anterior dental sector. Case presentation: A 41-year-old Mexican woman. Extra and intraoral examination was performed, the dental treatment included connective tissue graft and rehabilitation with Zirconia. Conclusion: Surgery of residual alveolar ridge augmentation with connective tissue graft gives the patient favorable aesthetic results in the anterior area when it will be rehabilitated.

Reconstructive plastic surgery allows the hard and soft tissues of the alveolar ridge to be restored to their previous dimensions and gives the restorative dentist the opportunity to provide patients with fixed prostheses that are truly aesthetic and that will improve Dentofacial harmony [2]
It consists of three basic approaches: Placement of a gross and free mucosal autograft, type “onlay” in the defect of the ridge, placement of an autograft of fibrous connective tissue sub epithelial at the site of the defect and placement of sub periosteal hydroxyapatite in the deformity [4]
Summary
In aesthetic and restorative dentistry, before performing any treatment when the main objective is to correct an aesthetic defect or keratinized gingiva, the tissue volume required to eliminate the deformity of the alveolar ridge must be ana-. Reconstructive plastic surgery allows the hard and soft tissues of the alveolar ridge to be restored to their previous dimensions and gives the restorative dentist the opportunity to provide patients with fixed prostheses that are truly aesthetic and that will improve Dentofacial harmony [2] In the literature, they have been presented with several surgical modifications for the increase of the localized ridge. In tunnel graft procedures [5] [7], a sub-epithelial envelope is created in the area of the ridge deformity This preparation could be developed with three different incision techniques; First, the technique consists of a coronary incision made by palatal or lingual defect, called coronal-apical; a second technique that is based on a horizontal incision near the mucogingival junction through the vestibular area, called apical-coronal [5], or the third technique includes one or two vertical incisions with a large lateral load bevel on either side of the defect [7]. The objective of this case report was to demonstrate how the technique of tissue modification in an area with a class b defect of Allen allows the correction of aesthetics by using Zirconia crowns in the anterior sector
