Maintenance of Segmental Maxillary Expansion: The Use of Custom, Virtually Designed, and Manufactured Palatal Appliances Without the Use of an Occlusal Splint.

Expansion of the maxilla using a segmental Le Fort I osteotomy is a routine and commonly used procedure in the treatment of dentofacial deformities. Although orthognathic surgery has seen tremendous advancement in technology, including virtual surgical planning and customized hardware, some room for advancement exists in the maintenance of surgical maxillary expansion. Traditionally, this has been accomplished with retention of a maxillary occlusal splint 4 to 8 weeks postoperatively.

Internal Maxillary Artery Preoperative Embolization Using n-Butyl Cyanoacrylate and Pushable Coils for Temporomandibular Joint Ankylosis Surgery.

Background: Temporomandibular joint (TMJ) ankylosis causes disability through impaired digestion, mastication, speech, and appearance. Surgical treatment increases range of motion with resultant functional improvement. However, substantial perioperative blood loss can occur (up to 3 L) if the internal maxillary artery (IMAX) is injured as it traverses the ankylotic mass.

Zoledronate, smoking, and obesity are strong risk factors for osteonecrosis of the jaw: a case-control study.

Purpose: Bisphosphonates (BPs) effectively treat metastatic bone disease, hypercalcemia, and osteoporosis. BP exposure, however, may be associated with osteonecrosis of the jaw (ONJ). The aim of the present study was to estimate the magnitude of the association between intravenous (IV) BP exposure and ONJ, and to identify potential confounders.

Active Raman sounding of the earth's water vapor field.

The typically weak cross-sections characteristic of Raman processes has historically limited their use in atmospheric remote sensing to nighttime application. However, with advances in instrumentation and techniques, it is now possible to apply Raman lidar to the monitoring of atmospheric water vapor, aerosols and clouds throughout the diurnal cycle. Upper tropospheric and lower stratospheric measurements of water vapor using Raman lidar are also possible but are limited to nighttime and require long integration times.
