Use of Buccal Fat Pad in the Treatment of Peri-Implant Mucosal Defect: A Case Report.

The present study describes a clinical case in which the buccal fat pad (BFP) was used to improve the contour of the peri-implant mucosa. To our knowledge, this is the first case report of such an application in the literature. A 58-year-old woman presented with teeth #2 and #3 missing and an indication for extraction of tooth #4. After clinical examination and CBCT analysis, immediate implants were placed in the region of the extracted tooth and that of tooth #2 for prosthetic rehabilitation using a three-unit fixed partial denture. There was an extensive mucosal defect in the region of tooth #3, with vertical and horizontal changes in the contour of the mucosa. As an alternative to the use of a subepithelial connective tissue graft, we opted for displacement of the BFP and its accommodation on the alveolar ridge of tooth #3 to improve the buccal tissue contour. After 5 years of follow-up, satisfactory gain and maintenance of mucosal volume were observed in the treated area, as well as improvement of buccal tissue contour. The use of BFP seems to be a feasible alternative for filling and treating peri-implant mucosal defects.

Evaluation of the impact of preoperative use of dexamethasone and cyclobenzaprine in surgical extraction of lower third molars on trismus by electromyographic analysis.

PURPOSE: The aim of this study was to evaluate the influence of cyclobenzaprine and dexamethasone on ​the electrical activity of the masticatory muscles in patients who had undergone lower third molar surgery. METHODS: Thirty bilateral impacted lower third molars with indication of extraction were randomised into three groups: the control group, the dexamethasone, and the cyclobenzaprine group. To obtain muscular electrical activity and mouth opening, an electromyographic device was used at mandibular rest and maximum voluntary contraction and compared pre- and post-operatively. RESULTS: During muscle contraction, no significant difference was observed in the electromyographic records on the non-operated side. On the operated side, there was a reduction in electrical activity for both drugs pre-operatively and immediately post-operatively compared to the control group. All pharmacological agents promoted a higher mouth opening compared to control group. CONCLUSION: The results suggest that dexamethasone and cyclobenzaprine may be useful as an adjuvant in the prevention of motor dysfunctions in third molar surgery.

A large dentigerous cyst treated with decompression and orthosurgical traction: a case report.

This article presents the case of an 8-year-old patient who presented with a large radiolucency associated with the maxillary left canine and a supernumerary tooth. A computed tomography scan showed the radiolucency was in close proximity to the roots of the anterior teeth, with no areas of root resorption, and expansion into the left maxillary sinus. The boundaries of the maxillary sinus floor were still preserved. After positive aspiration of intralesional liquid and due to the large size of the radiolucency, a decompression technique was selected to preserve the permanent canine. Surgery was performed to remove the supernumerary tooth, followed by orthodontic treatment and surgery to allow access for orthodontic traction of the permanent canine. More than 5 years post-treatment, no recurrence was observed and the therapeutic option to position and preserve the permanent canine was successful.
