[Intermediate and longitudinal radiographic examinations of edentulous jaws with osseointegrated implants]

A previous paper summarized preoperative radiographic examinations, and the present paper is dealing with intermediate examinations following abutment operation as well as longitudinal examinations subsequent to prosthetic restoration. The difficulties in detecting incomplete fixture-abutment connection, and the need for identity of periodical radiographs are discussed. The operator is faced with great problems of film placement and projection angles when radiographing fixtures embedded in jaw bone. The main purposes of longitudinal examinations are to control marginal bone level changes and perifixtural bone quality. Radiography is also essential in diagnosing complications, e.g. loss of osseointegration and fixture fractures.
