Ecological explanations have been put forward to account for the precocious or delayed development of patency in ducts leading to the vomeronasal organ (VNO) in certain mammals. Perinatal function may be related, in part, to the patency or fusion of the vomeronasal and nasopalatine (NPD) ducts. However, few studies have focused on NPD development in primates, which generally have a prolonged pe...

The Nasopalatine duct cysts (NPDCs) are the most common developmental, epithelial and non-odontogenic of maxilla. They generally asymptomatic diagnosed on routine clinical or radiographic examination. should however be distinguished from large incisive fossae. On attaining a size, they may cause symptoms like pain itching, root resorption, teeth displacement bone perforation. We report case gia...

PURPOSE The purpose of this review was to highlight anatomic and biomechanical aspects of atrophic maxillae for implant possibilities. MATERIALS AND METHODS A MEDLINE electronic search of the years 1966 to 2009 was conducted with the keywords "atrophic,""resorbed,""edentulous," and "maxilla." RESULTS Twenty papers presented the following findings: (1) previous use of a removable prosthesis ...
