OBJECTIVE To analyze the long-term effects of subcranial surgery for anterior skull base tumors on facial growth. STUDY DESIGN AND SETTING Retrospective study (1994 to 2004) in a university-affiliated hospital. Of 108 patients who underwent a subcranial surgical approach for anterior skull base tumors, six adolescents and five young adults fulfilled study entry criteria for age and follow-up ...

The purpose of this study was to compare side-by-side two different titanium screw-type implants in the maxillae of miniature pigs. The test implants had a machined and acid-etched surface (Osseotite) whereas the control implants were sandblasted and acid-etched (SLA). After 4, 8, and 12 weeks of healing, removal torque testing was performed to evaluate the shear strength of the bone-implant in...

Supernumerary teeth are additional teeth besides the normal series and can be found in any region of the dental arch. Supernumerary teeth can be classified according to their form and locations. Early diagnosis and treatment of patients with supernumerary teeth may prevent or minimize complications. The treatment options depend on the type and position of the supernumerary tooth and its effect ...

The purpose of this study was to evaluate retrospectively, after a period of 6-48 months follow-up of prosthetic loading, the survival rate of 103 zygomatic implants inserted in 55 totally edentulous severely resorbed upper jaws. Fifty-five consecutive patients, 41 females and 14 males, with severe maxillary bone resorption were rehabilitated by means of a fixed prosthesis supported by either 1...

Objective: This study investigated the frequency of anatomic variations in sinonasal region with septal deviation and relationship these developmental direction maxilla cone-beam computed tomography images. Material Methods: Forty-eight patients who underwent orthognathic surgery were included this study. These divided into 3 groups: normal (n=16), prognathic retrognathic (n=16) by determining ...

An ovigerous female of Argulus matuii Sikama, 1938 was collected from the body surface a yellowfin seabream Acanthopagrus latus (Houttuyn, 1782) in cove facing Bungo Channel off Ehime Prefecture, western Japan. This represents new host record for A. matuii, and is herein described. female, which fixed preserved 70% ethanol, showed prominent coloration, i.e., six streaks yellow fringed with dark...

Greater understanding and acceptance of the new concept "bone quality", which was proposed by the National Institutes of Health and is based on bone cells and collagen fibers, are required. The novel protein Semaphorin3A (Sema3A) is associated with osteoprotection by regulating bone cells. The aims of this study were to investigate the effects of mechanical loads on Sema3A production and bone q...
