Oral rehabilitation of edentulous jaws with one-piece implants: a case series

The popularity of one piece implants has increased considerably between patients and dentists. The advantages of one-piece immediate loading for rehabilitation of edentulous mandibles is to reduce the number of interventions and timing of prosthetic. These parameters can be better controlled with a one-piece implant. Twenty-one patients with one-piece implants inserted in totally edentulous mandibles were considered for this retrospective study. Inclusion criteria were: Good oral hygiene, absence of lesions of the oral mucosa, no smoking or smoking less than 20 cigarettes a day, drinking less than 2 glasses of wine a day, good general health no pregnancy. Twenty-one (12 females 9 males) patients were enrolled in this retrospective study. The mean follow-up was 1 years. A total 84 one-piece implants (Biohorizon, Italy) were inserted in edentulous mandible. Implants diameter was 3.0 mm in all fixtures. Implants length was equal and longer than 12 mm in 44 and 40 fixtures respectively. 48 were inserted in females 36 in males (range 33-67; mean age 58.3). One-piece immediate loading implants has no difference in survival rate respect to two-piece implant and delayed loading for rehabilitation of totally edentulous mandibles. In conclusion one-piece immediate loading implant is a reliable device for mandible rehabilitation.
