Radiographic Journey Through Implant Treatment

Figure 16. (a) This cemented two-unit fixed prosthesis (splinted crowns) 36-37 was clinically mobile. A slight gap is present between the abutments and the implant platforms especially at the implant 37. Note the "absence" of the abutment screw within the implant 36. This observation is important because it implies that this fixed prosthesis may be removed by accessing the distal abutment screw only. This cemented prosthesis had to be cut off and a new screw-retained fixed prosthesis was fabricated as part of an overall treatment plan. (b) The new two-unit screw-retained fixed prosthesis. Note the presence of both abutment screws as well as the depth of their positions within the implants (screw chambers). In particular, note that depth of abutment screw position within the implant screw chamber of implant 37 between the old loose prosthesis (a) and the new one (b).

INTRODUCTIONExcellent theoretical knowledge and clinical skills provide a firm foundation for success in implant dentistry.

Radiographic prescription is often needed to provide a more complete picture of the current clinical situation and to guide further … Read more

A Microsurgical Approach for the Regeneration of Osseous Defects

INTRODUCTIONA major issue for the near future is the growing incidence of peri-implant osteitis (Fig. 1). Depending on the study, between 25-53% of patients with implants in Europe have peri-implant osteitis.1 It is not surprising that patients that did not take care of their natural teeth do not take better care of their implants. The … Read more
