“ At 0.7 GHz, it's seen that strong electric fields are excited in slot 1, and
symmetric surface currents around the boundary of slot 1 are
additionally seen. 1997) and Bergendal & Engquist (1998)
who used implants with a machined surface (5-12 months implants survival 72.4-79%) and much like those reported by Mangano et al.
Mangano et al. (2011) reported that nearly all of complications have been related to the weakness
of the anchorage elements connecting bar and overdenture.
The mean marginal bone loss between baseline (placement of the overdenture) and the 5-12 months analysis was restricted in both
teams and again comparable to those reported by
Mangano et al. Rotational panoramic radiographs, lateral cephalograms and postero-anterior oblique radiographs have
been made to assess bone quantity and potential pathology.
Nevertheless, bone loss as a sign of peri-implantitis couldn't be reliably excluded in some patients earlier than the 5-yr analysis period.
On this research, the patient-stage incidence of peri-implant mucositis was
41.7% and of peri-implantitis was 8.3% within the four implants group.
Incidence of peri-implantitis after 5 years was 8.3% and
4.5% in the four and 6 implants teams respectively.
Additionally in fully edentulous patients, however for mandibular overdentures, 51.9% peri-implant mucositis and 16.9% peri-implantitis was reported after 5 years (Meijer et al. ”
