Enxerto de tecido mole ceratinizado com ancoragem externa em região interforaminal em mandíbula

Abstract

The rehabilitation of the patient with severe resorption of the mandibular ridge is a challenging issue in surgical practice due to the present problems regarding retention and stability of the prosthesis. As it consequently presents a shallow lingual and buccal vestibule, muscle insertions closer to or at the level of the crest of the ridge together with the lack of adherent keratinized mucosa, which are considered risk factors for the long-term success of dental implants. For the elimination of these interferences, surgery is indicated, the objective of this study is to describe a modified surgical approach of grafting of the palatal mucosa accompanied by a vestibuloplasty and lingual sulcoplasty simultaneously with the repositioning of the ducts of the sublingual glands, to increase the depth of the lingual/buccal vestibule shallow, correcting the positioning of the ducts of the sublingual glands and gain of keratinized tissue around the previously installed dental implants. To this end, the methodology adopted was a review of the relevant updated literature and description of a clinical case report of a female patient, 60 years old, who underwent palatine mucosal graft surgery, followed by a vestibuloplasty and lingual sulcoplasty simultaneously with the repositioning of the ducts of the sublingual glands, with external anchorage in the interforaminal region of the mandible. Finishing the treatment with the delivery of the prostheses on the protocol-type implants in the lower region and a new upper removable total prosthesis. It was concluded that the graft of the palatal mucosa with external anchorage in the interforaminal region, simultaneous to vestibuloplasty and lingual sulcoplasty, is an effective approach to increase buccal and lingual depth, with gain of keratinized tissue around the implants, in severely affected mandibular ridges. reabsorbed. In addition, it provides repositioning of the ducts of the sublingual glands.
