UittrekselImplant rehabilitation of the posterior maxilla has become a standard treatment in contemporary dentistry. However, in cases of extreme maxillary atrophy, bone augmentation by means of a lateral wall sinus floor augmentation prior to implant placement is necessary. Several graft materials are available, however, data regarding the long term stability of these grafts are scarce. Therefore, the first goal of this thesis was to evaluate the vertical and volumetric resorption of a bovine bone xenograft after sinus lifting. Other goals related to the implant survival and patient-reported outcome measures after this type of treatment.
A second part of the thesis relates to implant surgery itself, more specifically to the accuracy of implant placement. As the implant location is of the utmost importance in the prevention of aesthetic, biological or technical complications, the next objective was to evaluate 3 different surgery protocols in terms of accuracy: free-handed surgery, pilot-drill guided surgery and fully-guided surgery. Finally, a cost-effectiveness analysis was performed based on the accuracy.
