Causes of Implant Failure and Subsequent Removal: A Retrospective Study in a Hospital setting.

Despite high rates of success for dental implants, implant failure due to several causes may require explantation. In the present retrospective study, implants removed between 2000 and 2022 have been registered and the cause of removal has been established. All implants were removed by a single operator (PPM) in the department of Oral Surgery of the George Eastman Dental Hospital in Rome, Italy.

Two-year prospective clinical comparison of immediate replacement vs. immediate restoration of single tooth in the esthetic zone.

Aim: To compare the immediate restoration of single implants in the esthetic zones performed on implants placed immediately after tooth extraction or 8 weeks later (immediate replacement vs. immediate restoration).

Methods: Sixteen patients (10 women and 6 men) with a mean age of 35 years (ranging from 21 to 49 years old) were treated from 2004 to 2005 for single-tooth replacement in the upper arch.

Maxillary sinus grafting with Bio-Oss or Straumann Bone Ceramic: histomorphometric results from a randomized controlled multicenter clinical trial.

Introduction: This investigation was designed to compare the histomorphometric results from sinus floor augmentation with anorganic bovine bone (ABB) and a new biphasic calcium phosphate, Straumann Bone Ceramic (BCP).

Materials And Methods: Forty-eight maxillary sinuses were treated in 37 patients. Residual bone width was > or =6 mm and height was > or =3 mm and <8 mm.

Dentin dysplasia type I. Report of case and ultrastructural study.

Radicular dentin dysplasia (DD-I) is a rare hereditary dental alteration. It is characterized clinically by almost normal looking crowns and severe hypermobility of the teeth. The radiographic analysis, on the other hand, discloses the obliteration of all pulp chambers, the short, malformed roots and plenty of periapical bone radiolucencies on noncarious teeth.
