A 10-year-old Chinese girl with two accessory maxillae and bilateral Tessier no. 7 clefts is presented. Radiographic examination showed two accessory maxillae, each containing 5 or 6 supernumerary permanent teeth. The two accessory maxillae extended from the inside of the zygomatic arch to the maxillary tuberosity symmetrically. Duplication of the maxilla is always associated with Amniotic Band...

BACKGROUND The purpose of this study was to reveal the structural properties that need to be considered in dental implant treatment by investigating differences between dentulous and edentulous maxillae in the three-dimensional (3D) microstructure of the incisive canals (ICs) and their surrounding bone. METHODS A total of 40 maxillary bones comprising 20 dentulous maxillae and 20 edentulous m...

PURPOSE The purpose of this retrospective study was to determine the success of Brånemark System TiUnite implants (Nobel Biocare/Sweden) placed in partially or completely edentulous jaws restored with fixed or removable prostheses. PATIENTS AND METHODS A total of 131 jaws from 110 patients (64 maxillae and 67 mandibles) received 472 implants from July 2003 until March 2008. The patients inclu...

The external morphology of the heads of adult male and female Cixiopsis punctatus (Matsumura) (Hemiptera: Fulgoromorpha: Tropiduchidae) was studied using scanning electron microscopy. Eleven types of sensilla or sensory organs were identified: trichoid sensilla on the pedicel, scape, maxillae, and labium; campaniform sensilla on the antennal pedicel, antennal scape, maxillae, and labium; plate ...

This paper describes the file of the mandible, the apices of the maxillae, the rupturing device on the maxillae, and the internal structures of the mouthparts in sixty representatives of the nepomorphan families (Heteroptera), using scanning electron microscopy. Eight morphologically distinct types of files are identified on the mandibular tip, as well as six distinct types of the maxillary end...

a primary intraosseous carcinoma (pioc) is a squamous cell carcinoma arising within the  jawbone andshould be differentiated from a malignant ameloblastoma.  it  is not due to arising from an odontogenic cyst or tumor. the possibility of the lesion being  a metastasis fromanotherprimary site should be considered, and excluded by a careful history and examination. the diagnosis of a pioc is rare...

Although most retention problems of prostheses are concentrated in the mandible, patients have similar problems in the maxillae. Retention of prostheses can be improved by the use of two or four implants, either with retentive anchors or with a bar in the frontal part of the maxillae. The method of planning and placement of I.T.I. Bonefit implants is described.

In this chapter, two main treatment options for severely edentulous atrophic posterior maxillae—bone augmentation procedure and zygomatic implant application—are presented. Poor bone quality and insufficient bone volume due to critical jawbone atrophy in the posterior maxillae are addressed as the main factors contribute to the failure of dental implant system. The rationales behind the introdu...
