Clinical evaluation of screw-vent implant versus IMZ implant in natural tooth-implant fixed restorations

Abstract

The current study comprised of 20 implants inserts m 20 healthy patients. All patients shared in this study have no contrainindication for

the surgical intervention. In all cases the implant fixtures were inserted into the posterior free-end saddle situation of the mandible. Cases were classified equally into 2 groups (A and B)

Screw-vent implant fixtures were inserted in patients •of group

(A) and IMZ implant fixtures were inserted in patients of group (B).

The selected fixtures was inserted in the jaw bone according to the Branemark osseointegrated protocol. All the patients were followed-up and the success of the implantation procedures was assessed during the pre-loading (healing) period at 2, 4, 8 and 12 weeks post-operatively. Assessment was also made at 1, 3, 6 and 12 months after loading with the super structure. The clinical parameters included Mobility Index (MI), Probing

Depth (PD), Gingival Index (GI) and Bleeding Index (BI)

The radiographs comprised intra-oral radiographs and panoramic X-rays. The electrophoretic analysis depend on the glycosaminoglycns (GAG) profile of gingival crevicular fluid (GCF) to detect possible detrimental bony changes that could not be clinically evaluated. According to the clinically and radiographic assessment fixtures

were defined as "osseointegrated" as there was no mobility detected
