Effects of implant angulation, impression material, and variation in arch curvature width on implant transfer model accuracy.

Purpose: The effects of implant angulation, impression material, and variation in width of the arch curvature on transfer models were evaluated.

Materials And Methods: Three edentulous maxillary epoxy resin models were fabricated, and six internal-connection implant analogs were placed in different locations and different angulations in each model. In the first model, implants were positioned in the canine, first premolar, and first molar regions, and all analogs were positioned parallel to each other and perpendicular to the horizontal crestal plane (parallel model).

Rehabilitation of maxillary anterior esthetics by alveolar distraction osteogenesis with immediate implant placement: a case report.

Esthetic reconstruction of severe soft and hard tissue deficiencies is the utmost challenge in implant dentistry. To prevent postoperative bone resorption and to control the amount of hard and soft tissue volume, distraction osteogenesis followed by immediate implant placement has been proven to be a promising combined technique. The aim of this report is to introduce a treatment strategy to maintain anterior esthetics and to control hard and soft tissue volume in a case, treated with the combined technique of vertical alveolar distraction and immediate implant placement.

Effects of Bartter's syndrome on dentition and dental treatment: a clinical report.

Bartter's syndrome is an autosomal recessive form of severe volume depletion due to renal salt wasting. This clinical report describes the prosthodontic treatment for a 24-year-old man who suffers from Bartter's syndrome. The treatment plan included endodontic treatment of the maxillary anterior incisors and placement of cast dowel-and-core restorations because of reduced crown height.
