Article Synopsis
- A 50-year-old man with significant dental misalignment sought a complete oral rehabilitation to address issues like a deep bite, gummy smile, and crossbite.
- He underwent a thorough treatment plan that included orthodontics, orthognathic surgery, and dental implants, aimed at correcting jaw deformities and augmenting the alveolar ridge.
- After two years of treatment, he experienced notable improvements in appearance, stability, and functionality of his teeth and jaw.
Background: Immediate restoration during implant placement in the premaxillary area can achieve a favorable esthetic result. However, the treatment always poses a great challenge to clinicians, especially for patients with preexisting soft and hard tissue deficiencies. The aim of this clinical report was to present a protocol for a multidisciplinary approach to provide an immediate implant restoration for patients with ridge deficiency.

Introduction: Stress-induced martensite formation with stress hysteresis that changes the elasticity and stiffness of nickel-titanium (Ni-Ti) wire influences the sliding mechanics of archwire-guided tooth movement. This in-vitro study investigated the frictional behavior of an improved superelastic Ni-Ti wire with low-stress hysteresis.
Methods: Improved superelastic Ni-Ti alloy wires (L & H Titan, Tomy International, Tokyo, Japan) with low-stress hysteresis were examined by using 3-point bending and frictional resistance tests with a universal test machine at a constant temperature of 35 degrees C, and compared with the former conventional austenitic-active superelastic Ni-Ti wires (Sentalloy, Tomy International).
