Implant-Supported Removable Partial Denture: An Approach to Rehabilitate Maxillary Kennedy Class I.
The different resiliencies between the supporting structures of a distal extension removable partial denture can lead to horizontal and vertical forces that may have adverse effects during functional and para functional activities.
The continue resorption of the underlying residual alveolar ridges affect the retention, support and stability which induce changes in the occlusal condition, leading to overload of the anterior teeth.
However, the most difficult problem to solve would be the anterior retention induced by the low periodontal value of the incisors as well as the visibility of the vestibular arm of the clasp, which is unsightly in the anterior region.
Thanks to implantology, it is possible to improve the performance and the biomechanical behavior of the free end saddle. Placing plant in well-studied sites prevents bone resorption, increase the retention and the stability of the RPD, reduce the stress and the number of retainer on the anterior teeth, in addition to be
more comfortable and more accepted by patients.
According to this study, the advent of dental implants
made possible to substitute the missing teeth with fixed implant supported dentures as the first choice treatment to overcome inconveniences of RPD. However, this indication may not be suitable for all patients due to financial, anatomical or systemic health conditions.
