Purpose: To evaluate the efficacy and complications of simplified graded inferior oblique anterior transposition (IOAT) in treating at least 10 PD vertical deviation in the primary position and inferior oblique muscle overaction (IOOA).

Methods: This retrospective study reviewed the medical records of 65 patients treated with simplified graded IOAT procedures for both vertical deviation and IOOA. Patients were grouped according to vertical deviation in the primary position.

Objective: This case report presents the interdisciplinary retreatment of a patient with a worn full-mouth rehabilitation using defect-oriented restorations, horizontal preparations, and vertical dimension of occlusion (VDO) increase.

Clinical Considerations: A 58-year-old woman with a previous full-mouth rehabilitation presented with worn dentition, loss of VDO, and reduced posterior support. Examination revealed signs of parafunctional habits, tetracycline-stained teeth, and compromised aesthetics with exposed discolored teeth and open embrasure spaces.

Article Synopsis
  • A case report highlights the orthodontic treatment of a 26-year-old woman with severe scissor bite using temporary anchorage devices (TADs) and fixed braces.
  • TADs were utilized to intrude extruded molars, correct dental midline, control molar inclination, and enhance overall dental relationships.
  • The successful treatment not only resolved the scissor bite but also improved the patient's occlusal function and facial aesthetics, with CBCT imaging recommended for effective three-dimensional treatment planning.

Atmospheric refraction imposes a fundamental limitation on the accuracy and precision of geodetic measurements that utilize electromagnetic waves. For terrestrial observations at optical wavelengths recorded over flat terrain, the vertical temperature gradient controls the bending of the rays thus affecting mostly the vertical angle measurement. The rules of thumb for mitigating these effects (variation ranges and short-term fluctuations) are based on intuition and practitioner experience.

Background/purpose: Studies have indicated that 50%-55% of the population have malocclusion, and approximately 5%-10% require orthognathic surgery to correct this condition. Optimal placement of plates and screws significantly affects the success rate of the surgery and postoperative stability. This study evaluates the cortical thickness of the maxillary bone in the nasomaxillary and zygomaticomaxillary buttress regions in Taiwanese patients based on cone-beam computed tomography (CBCT) images.
