Supportive Implant Therapy Protocol for the Patient with Single or Multiple Implants

by C. Fritz,123 L.M. Dakin,1 D.M. Lavoie,1 S.M. Sabo,1 C.P. Hamm,1

While the advent of implant dentistry has provided the option of a fixed prosthetic solution, the responsibility for the maintenance of implant dentistry often rests with the patient and the dental hygienist. Without supportive implant therapy, the possibility of peri-implantitis

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).
