A novel technique to retrieve cold-welded implant abutment: A case series.

Abutment fracture is a complication of dental implant treatment. When an abutment breaks, the remaining part should be retrieved without damaging the implant hex. In many cases, the implant-abutment connection is cold-welded, which makes it difficult to remove the remaining part.

Rehabilitation of an Auricular Defect Using Surgical Stent.

Reconstruction of a facial defect is a complex modality either surgically or prosthetically, depending on the site, size, etiology, severity, age, and the patient's expectation. The loss of an auricle, in the presence of an auditory canal, affects hearing, because the auricle gathers sound and directs it into the canal. The auricle acts as a resonator to slightly amplify lower frequency sounds and helps to localize sounds, especially in conjunction with the other ear.

Comparative study of abutment screw loosening with or without adhesive material.

Purpose: The purpose of this study was to achieve more retention and stability and to delay or prevent screw loosening.

Materials And Methods: Twenty implants (Implantium 3.4 mm, Dentium, Seoul, Korea) were divided into 2 groups (n = 20).
