This paper presents jaw movement data for the coronal consonants of Central Arrernte. It compares jaw movement for stops with jaw movement for nasals and laterals, across dental, alveolar, retroflex and alveo-palatal places of articulation. Results suggest that when there is a clear spectral peak for the release burst, as is the case primarily for the palatal, but also for the alveolar and retr...

This study aimed to evaluate the effectiveness of fluorescence-based methods (DIAGNOdent, LF; DIAGNOdent pen, LFpen, and VistaProof fluorescence camera, FC) in detecting demineralization and remineralization on smooth surfaces in situ. Ten volunteers wore acrylic palatal appliances, each containing 6 enamel blocks that were demineralized for 14 days by exposure to a 20% sucrose solution and 3 o...

BACKGROUND AND AIM: Maxillofacial defects due to malignant or benign tumors or congenital defects often result in complications such as the impairment of facial aesthetic, mastication, speech, and swallowing. Remedy of these defects, especially in a dentate patient is an important challenge in prosthodontics. Maxillectomy can lead to severe anatomical changes f...

Introduction: Prosthodontic management of palatal defects has been employed for many years. Palatal defects of any extent cause multiple problems in speech, mastication and aesthetics. Obturator prosthesis for an edentulous patient is more critical in terms of its movements as there is no mechanical retention available. Obturators and facial prostheses are important not only for rehabilitation ...

BACKGROUND Maxillary defects are managed by prosthodontic rehabilitation using obturators. This rehabilitation goes through various stages, which invariably affects the quality-of-life of the patients. AIM This study aims to analyze the types and design of obturators used in the rehabilitation of maxillary defects at a tertiary health institution in Nigeria. MATERIALS AND METHODS This is a ...

Most patients who have undergone resection of the maxillae due to benign or malignant tumors in the palatomaxillary region present with speech and swallowing disorders. Coupling of the oral and nasal cavities increases nasal resonance, resulting in hypernasality and unintelligible speech. Prosthodontic rehabilitation of maxillary resections with effective separation of the oral and nasal caviti...

The study evaluated the effects of obturators on respiratory function by analyzing the changes in nasal anatomic structures and physiologic function in maxillectomy patients with and without obturators. Twenty-six patients who underwent maxillectomy were chosen and rehabilitated with obturators by a single maxillofacial prosthodontist. The geometric shape of the nasal cavity, the nasal airway r...

BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/bcr-2013010450 DESCRIPTION A 28-year-old woman with a history of snorting heroin and cocaine was admitted with facial cellulitis secondary to a dental phlegmon. She reported rhinolalia, occasional nasal regurgitation of food and a burning sensation in her nose and throat while eating. She ...

The use of photoelastic analysis contributes to the rehabilitation of patients with oral-sinus-nasal sequelae, which in turn affect important functions such as chewing, swallowing, and speech. The prosthetic rehabilitation with implant-retained dentures is a suitable treatment option. The purpose of this study was to verify, by using a photoelastic analysis, the stress distribution in implant-r...

Maxillary resection results in a discontinuity of the oral nasal and maxillary sinus cavities. Defect of any extent results in significant disabilities experienced by the patient. This may be manifested as difficulties in speech, mastication and esthetics.Prosthetic rehabilitation in the form of a palatal obturator is usually required to cover the defect and restore normal functions. In the cas...
