Higher electromyographic (EMG) activity levels of corrugator and zygomatic face muscles have been reported to be pretreatment predictors of better clinical outcome in depressed patients. We tested this possibility in 29 drug-free, rigorously diagnosed subjects by measuring low-level EMG activity of corrugator and zygomatic muscles during resting and three imagery states (happy, typical day, sad...

INTRODUCTION Zygomatic implants are a good rehabilitation alternative for upper maxilla with severe bone reabsorption. These implants reduce the need for onlay-type bone grafting in the posterior sectors and for maxillary sinus lift procedures - limiting the use of bone grafts to the anterior zone of the upper jaw in those cases where grafting is considered necessary. OBJECTIVE To evaluate th...

Introduction: Zygomatic implants are a good rehabilitation alternative for upper maxilla with severe bone reabsorption. These implants reduce the need for onlay-type bone grafting in the posterior sectors and for maxillary sinus lift procedures limiting the use of bone grafts to the anterior zone of the upper jaw in those cases where grafting is considered necessary. Objective: To evaluate the ...

The purpose of this study was to evaluate retrospectively, after a period of 6-48 months follow-up of prosthetic loading, the survival rate of 103 zygomatic implants inserted in 55 totally edentulous severely resorbed upper jaws. Fifty-five consecutive patients, 41 females and 14 males, with severe maxillary bone resorption were rehabilitated by means of a fixed prosthesis supported by either 1...

T o improve midfacial soft-tissue sagging, it is sometimes necessary to release the zygomatic and upper masseteric retaining ligaments in the sub-superficial musculoaponeu-rotic system (SMAS) plane. Release of these ligaments needs to be done carefully to avoid any injuries to the branches of the facial nerve. Some of the zygomatic branches run toward the zygomaticus major muscle and are locate...

PURPOSE The aim of the present cross-sectional study was to propose a classification system based on a cross-sectional survey of zygomatic implant cases. MATERIALS AND METHODS Cone beam computerised tomography (CBCT) postoperative images and clinical intra-surgery photographs of 200 sites corresponding to 100 patients, treated with a total of 198 zygomatic implants in the maxilla according to...

The aim of this study was to assess the use of buccal fat pad (BFP) technique as an option to close oroantral communications (OAC) after removing failed zygomatic implants in a patient with a severely resorbed maxilla, and to determine the degree of patient satisfaction. A 64-year-old woman presented recurrent sinusitis and permanent oroantral communication caused by bilateral failed zygomatic ...

OBJECTIVES Odontogenic chronic rhinosinusitis (CRS) is an epidemiologically important disease process due, in part, to the increasingly commonplace use of dental restorative procedures such as zygomatic implantation. Traditional management of this clinical entity typically entails extraction of the infected hardware via an open or endoscopic approach. We describe a novel management strategy of ...

To assess the effectiveness of a dental instrument for reduction of isolated zygomatic arch fractures. Two patients were admitted to our clinic representing isolated unilateral zygomatic arch fracture. The common presenting complaints were pain, swelling and difficulty in mouth opening. Fractures were confirmed with plain radiography and computerized tomography. The fractures were reduced with ...

This report describes the possibility of treating a patient affected by unilateral cleft palate and an extremely atrophied edentulous maxilla using zygomatic implants inserted in a conventional manner and maxillary implants inserted by means of a computer-assisted surgery. A cross-arch prosthesis supported by 4 maxillary and 2 zygomatic implants may be an ideal mode of prosthetic rehabilitation...
