Reduced Epithelial Surface Activity is Related to a Higher Incidence of Facial Clefting in a/WySn Mice

22 Sep

Animal models of primary palate development have provided a great deal of information relative to both normal and abnormal development. The murine model has been particularly useful, because several strains have relatively high frequencies of spontaneous cleft lip with our without cleft palate, and other have no spontaneous frequency of CL(P).

The Morphologic and Biochemical Effects of Tensile Force Application

22 Sep

Studies of orthopedic expansion of cranial sutures have carefully documented that the biologic response is a widening of the suture followed by the production of connective tissue components (Hinrich- son and Storey, Storey, Cleall and associates, Murray and Cleall Ten Cate, Freeman, and Dickinson). By this remodeling activity, the suture re-establishes a configuration similar to […]

The Embryology of the Temporomandibular Joint

22 Sep

This study examined 63 human fetuses, ranging in size from 4.5 to 255 mm crown-rump, to follow the embryological development of the temporomandibular joint. Sagittal, coronal, and transverse sections of the joint region were prepared and stained either in Milligan’s trichrome, a connective tissue stain, or in hematoxylin and eosin. The results of the study […]

Repair of Surgical Clefts of the Hard Palate in Beagles from the Surgical Cleft Repair

22 Sep

The biological response to the repair of palatal clefts has been evaluated principally by monitoring craniofacial growth. Little is known about the regenerative ability of the repaired palate. In the present study, 18 Beagle pups (51 to 58 days old) were assigned to one of three groups: (1) control group, having no surgery; (2) cleft […]

Epithelial Bridging of the Primary Palate from the Journal of Craniofacial Genetics

22 Sep

Primary palatogenesis involves an intricate array of events. Cell migration, proliferation, differentiation, programmed death, and fusion occur. Prior to fusion, the morphology of the epithelium undergoes marked changes. Epithelial projections form and extend across the fusion site attaching by filopodia to the opposite prominenece. By appearance, the epithelium plays a critical role in facial development. In order […]

A Quantitative Approach from Effects of Force Magnitude on Sutural Model

22 Sep

Orthodontic tooth movement is dependent on the induction of a bony remodeling response by a mechanical force. Although sophisticated advances have been made in force delivery systems, relatively little is known to explain how changes in the applied forces affect the biologic system. For many years knowledge of the biologic response to an orthodontic force […]

Proper treatment planning is essential for successful outcomes, particularly with interdisciplinary dentofacial therapy (IDT) cases of skeletally mature patients who require orthodontic tooth movement. As such, pretreatment assessment of the periodontium is commonly evaluated by clinical measures and conventional two-dimensional radiog raphic review. In IDT cases, particularly those involving the worn or malposed dentition, positioning […]
