An angled narrow-diameter implant has been introduced for use in cases where the atrophic edentulous ridge is wide enough to accommodate narrow-diameter implants but the necessary implant angulations would make it impossible to fabricate an esthetically acceptable overdenture. A case is described in which such implants were placed and restored.

This case report described a new technique for immediately loading an implant-supported fixed screw-retained bridge that has flat abutments to achieve a superior passive fit. The definitive prosthetic bridge was placed within 72 hours from surgery and follow-up data over a 5-year period are presented. Good aesthetic results were achieved, and at the end of the follow-up period neither biological nor biomechanical complications were observed.

This study compares the convergence angle of preparations for posterior gold crowns made by fourth/ fifth year undergraduate dental students, clinical teaching staff and general dental practitioners. Sixty dies were cast from impressions previously taken of clinical preparations by clinicians within each of the four groups. Each die was trimmed and sectioned in both mesio-distal and bucco-lingual planes before being projected using an overhead projector, thereby enabling the convergence angle silhouette to be measured. The results show the greatest convergence angle range to be produced by the least experienced students (10 degrees - 82 degrees). However, no significant difference (p > 0.05) was found when students with one further year of experience were compared to experienced staff. The degree of conformity to the ideal taper (4 degrees - 14 degrees) was no greater than 50% for any of the groups.
