Background:
Implant surgery in the edentulous premaxilla is often challenging because of esthetic, phonetic, and biomechanical considerations. A number of bone augmentation methods have been developed specifically for implant placement in the severely resorbed maxilla. These include split ridge augmentation, distraction osteogenesis, ridge augmentation using guided bone regeneration with various kinds of graft materials, and sinus augmentation. An alternate method is the placement of an implant in the incisive canal (IC) to support the anterior maxilla for fully edentulous implant-supported prostheses.
Aim/Hypothesis:
The purpose of this retrospective study is to present a case series describing an alternative treatment concept for the rehabilitation of the atrophic maxilla that utilized the incisive canal as an implant site for dental implant insertion. Indications and limitations of the procedure will be discussed.
Material and Methods:
A total of 7 subjects had received 7 implants placed in the incisive canal to support fixed restorations with severe maxillary atrophic ridges.
Results:
Patients were followed for one year. All patients did not report any loss of sensation. One implant was failed before loading providing a success rate of 85 % of implants placed in the IC.
Conclusions and clinical implications:
Within the limits of this retrospective study, incisive canal implants placement should be considered as a treatment option in patients with severely resorbed ridges, they provide sufficient anterior support to enhance the biomechanics of an implant supported prostheses.
