Abstract

The dental implants in modern dentistry brought out a new era in everyday dental practice. Increasing of dental implants usage, various failures and complications has occurred. Failures and complications of dental implant treatments that can happen in implant surgery, in mechanical or prosthetic problem and in biological aspect. The aim of this study was to assess implant failures for 6 years as well as find out how to overcome implant failure. In Jeju National University hospital, 26 dental implants in 17 patients were removed by implant failure through 2013.1.1.―2018.12.31. Each implant failure case was analyzed in report form with various informations about failure retrospectively. The present study showed 26 failed dental implants of 17 patients were removed. 13 implants(50%) of 8 patients(47.06%) were failed before functional loading and 13 implants(50%) of 9 patients(52.94%) were failed after functional loading. 11 implants(42.31%) of 7 patients(41.18%) with medical disease were extracted. 6 implants(23.08%) of 5 patients(29.41%) with additive bone graft were failed. We discuss with 26 failed dental implants of 17 patients about their causes, solutions and prevention retrospectively for 6 past years. Precise diagnosis and treatment planning are needed. Medically compromised patients and patients with implants and additive bone grafts should be cautiously treated with high failing possibilities.

Abstract

In recent years, with the introduction of various restorative materials, restorations using CAD/CAM equipment have been increasing in the esthetic dentistry. The critical steps in the fabrication of indirect restorations with CAD/CAM equipment are proper cavity preparation and making accurate impressions. The process of tooth preparation for CAD/CAM restoration should include a mechanical understanding of milling. In addition, during tooth preparation, the clinician should be familiar with additional equipment and techniques for obtaining the convenience. In order to obtain an accurate oral scan, the clinician should understand the limitations of the oral scan and be skilled at techniques for obtaining a successful image when making oral scans. This article focused clinical guidelines for the preparation of CAD/CAM restorations and introduced clinical methods for making successful impression of oral scans in narrow and deep tooth cavity areas.

Abstract

The most important part of everyday root canal treatment is diagnosis about the morphology of tooth, root and root canal. Usually this procedure is performed by visual examination and radiographic (panoramic/periapical) examination. However, 2-dimentional radiography has several limitations such as imposition of anatomic structures including buccal/lingual root canals and distortion of images. Recently, owing to the increased interest in dental implant and affordable cost of CBCT equipment, CBCT has been introduced widely in local dental clinics. CBCT is characterized by their lower radiation dose and shorter exposure time than conventional CT scan, and ability of 3-dimentional reconstruction of the dento-alveolar structure. Also in endodontic field, the data from CBCT could be very helpful in diagnosing complex root canal anatomy, apical periodontitis, cause of failure and in determining treatment plan. However, there are some limitations such as radiation dose and artifact. Therefore, clinicians should know about indication, advantages and limitations of CBCT, and properly use it for successful root canal treatment to save the natural teeth.

Abstract

A cracked tooth is defined as an incomplete fracture initiated from the crown and extending subgingivally and usually directed mesiodistally. Cracked teeth were most frequently involved in mandibular and maxillary molars at the age of 50s. Cracks occurred mainly in nonbonded restorations such as gold and amalgam, and majority of cracks were found in intact teeth. A pulpal and periapical diagnosis is dependent on the extent of the crack and duration of the symptom. The pulp of a cracked tooth might become inflamed because of microleakage, which induces thermal sensitivity. Once the crack has extended and exposed the pulp, severe pulp and periapical pathosis will likely be present. In addition, the extended crack can cause a bony dehiscence with a resulting narrow and deep periodontal pocket. Therefore, early diagnosis of the cracked tooth and proper treatment planning are important for clinician.
