- BACKGROUND The consumption of simple carbohydrates, smoking, the diffusion of systemic diseases such as diabetes, which negatively impact on dentoperiodontal health, have contributed to increase the prevalence of edentulous subjects in theworld’s populationin the last years. Considering also the lengthening life expectancy we can affirm that universities, research institutes, industries and dental professionals will be involved to develop new rehabilitation techniques that meet geriatricpatient’s expectations, and than minimally invasive, easy to realized, affordable and versatile. The aim of the present study is to offer a critical re-evaluation of implant supported CAM-CAD bar retained overdenture in patients with edentulous maxilla.
- MATERIALS AND METHODS Three geriatic patients with edentulous maxilla were treated with 4 two-steps cylindrical,internal connection, sandblasted and threaded surface titanium implants, length 9,5 to 13 mm and diameter 3,4 to 3,8 mm. The two distal implants were placed in 1.5 area while the two central in 1.2-2.2 area. After an healing period of 2 months the implant were exposed, was taken an implant impression with pick-up technique and developed an implant-supported CAM-CAD titanium bar. Thus, it was made a bar overdenture.
- DISCUSSION The CAM-CADtitanium bar offers a passive and tension-free fit and a micrometer precision lower than 10μm. It can be used on any implant interface with an excellent predictability of results. The CAM-CAD overdenture bar allows a simplified and aesthetically advantageous rehabilitation and helps correct pronunciation. It is a semi-fixed solution and then permits the patient to maintain a good house hygiene. It is a complete implant-supported solution, than it reduces the edentulous ridge bone reabsorption and removes palate resin from prosthetic design with greater comfort and minimal emetic reflex.
- CONCLUSIONS The maxillary CAM-CAD bar overdenture is indicated for patients who need more retention and stability of the prosthesis. It also offers a cheaper solution than a fixed rehabilitation. Thanks to its versatility, the overdenture can be used even on severely reabsorbed maxilla, avoiding more invasive procedures like GBR and great sinus lift.
