Juvenile Facial Growth and Mimicry: A Preliminary 3D Study.

Studies focused on facial development during childhood have been conducted by means of 3D technology to provide modifications of anthropometric parameters. Facial mobility was also considered. This study proposed a 3D approach to facial growth changes.

Facial Mobility after Maxilla-Mandibular Advancement in Patients with Severe Obstructive Sleep Apnea Syndrome: A Three-Dimensional Study.

The functional results of surgery in terms of facial mobility are key elements in the treatment of patients. Little is actually known about changes in facial mobility following surgical treatment with maxillomandibular advancement (MMA). The three-dimensional (3D) methods study of basic facial movements in typical OSAS patients treated with MMA was the topic of the present research.

Evaluation of plate-related complications and efficacy in fibula free flap mandibular reconstruction.

Aim: The objective of this study was to evaluate the incidence of plate-related complications after vascularized bony reconstruction of the mandible, comparing the plate type used.

Patients And Methods: Between 2004 and December 2012, a total of 41 free osteocutaneous fibula flaps have been used in an equal number of patients for reconstruction of the mandible, at the Division of Maxillofacial surgery, San Giovanni Battista Hospital, University of Turin. Malignant pathology was the most common indication for segmental mandibulectomy.

Quantification of facial movements by optical instruments: surface laser scanning and optoelectronic three-dimensional motion analyzer.

The objective of this study was to assess the accuracy of displacements of tracing landmarks in standardized facial movements. Forty healthy persons were evaluated in 2 different groups (20 men and 20 women, aged 18-30 years) with optoelectronic motion analyzer and surface laser scanning. The displacements of tracing landmarks in brow lift and smile were calculated, and the 2 methods (optoelectronic motion analyzer and surface laser scanning) were compared in healthy persons.

Facial mobility after bimaxillary surgery in class III patients: a three-dimensional study.

Quantifying soft tissue changes after orthognathic surgery is increasingly important in surgical planning, but little is actually known about the changes in facial mobility after surgery. In the current study, we investigated facial mimics in patients before and after orthognathic surgery. Eleven patients with jaw discrepancy requiring maxillary and/or mandibular surgery were considered.

Growth-associated protein-43 immunoreactivity in human oral mucosa in dentate subjects, in edentulous patients and after implant-anchored rehabilitation.

Objectives: This study investigates expression of the neural growth-associated protein 43 (GAP-43) in the oral mucosa of (A) normal dentate subjects, (B) edentulous patients rehabilitated with conventional denture and (C) those rehabilitated with mandibular implant-retained overdentures (MIR-OVD), in the long term. This study evaluates morphological changes in the distribution and representation of sensory terminations and corpuscles in the alveolar mucosa under the action of different masticatory or prosthetic loads, in the three clinical groups.

Material And Methods: GAP-43 immunoreactivity (-ir) was compared with the distribution of nerves fibres in the mucosa, as visualised using anti-protein gene product 9.
