CEPHALOMETRIC ASSESSMENT OF HYOID BONE POSITION IN NIGERIAN PATIENTS WITH BIMAXILLARY INCISOR PROCLINATION.

Background: Hyoid bone though constitute a small proportion of the human skeleton, its importance in relation to other facial structures cannot be overemphasized. Several studies have reported on hyoid bone position in relation to various types of malocclusion, however, to our knowledge, there has been no study on the relationship between the hyoid bone and bimaxillary incisor proclination.

Aim: The aim of this study was to assess the relative position of hyoid bone in individuals with and without bimaxillary incisor proclination as well as other related demographic factors.

A CEPHALOMETRIC ANALYSIS OF THE MORPHOLOGY AND SIZE OF SELLA TURCICA IN NIGERIANS WITH NORMAL AND BIMAXILLARY INCISOR PROTRUSION.

Background: It has been suggested that bimaxillary protruded anterior teeth may be related to the sella turcica anatomically and embryologically through their common progenitors.

Aim: This study assessed the morphological variations and linear dimensions of sella turcica in a Nigerian population with normal and bimaxillary protruded teeth.

Methodology: Lateral cephalometric radiographs of orthodontic patients were assessed.

Response of the oral tissues to prolonged uninterrupted coverage by a removable partial denture. Case report.

The response of hard and soft oral tissues to prolonged uninterrupted wearing of a removable partial prosthesis in a Nigerian patient is discussed. To our knowledge only one case has been reported in the literature. In this case additional mucosal changes to the reported caries-free pattern is discussed.
