The Straumann® Mini Implant, thanks to its apically tapered shape offers good primary stability, allowing for under-preparation of the site.
Due to its apically tapered design, this implant offers adequate primary stability with minimum site preparation.
The implant body made of Roxolid®, an alloy of zirconium and titanium has excellent resistance properties. In addition to maintaining good bone preservation, the implant surface of the SLA® gives the implant a high bone integration.
It’s a monotype implant composed with an Optiloc® retention system, based on ADLC carbon giving the system an excellent wear resistance, able to remedy divergences or convergences between implants up 40 degrees.
64-year-old, non-smoker and healthy female wears a regular full arch prosthesis in the upper arch for 15 years and in the lower arch for 40 years (Fig.1, Fig. 2.a,b). The causes of edentulism are unknown but premature teeth loss due to periodontal disease and ethnic-cultural factors is assumed. The upper prosthesis needs to be relined and restored in some fracture points, while the lower prosthesis needs more stability.
For several years, the patient has no longer been able to tolerate the adhesive glue for the lower prosthesis and continuous direct and indirect relining have not yielded any positive results.
The amount of bone available in the lower arch is extremely low, with a very narrow and pointed ridge in the front part and an almost non-existent ridge in the posterior zone; moreover, the poor presence of keratinized epithelium is noted.
In the front of the lower jaw the shape of the alveolar processes is presented with a "knife-edged ridge form, adequate in height and inadequate in width" (IV-According Class to the Cawood and Howell's Classification), in the back it is a "depressed ridge form, with some basilar loss evident "(class VI).
