Immediate Loading of Dental Implants Inserted in Edentulous Maxillas and Mandibles: 5-Year Results of a Clinical Study.

The aim of the present study was to evaluate the long-term outcome of immediately loaded full-arch, fixed, one-piece prostheses supported by dental implants inserted in completely edentulous maxillae and mandibles. Twenty-eight completely edentulous jaws in 27 patients were treated with screw-fixed provisional prostheses on the same day as implant insertion. A total of 189 implants were inserted into the jaws of the patients.

[Sedation during day surgery for oral implantation].

Background: Oral implantation surgery is performed under sedation without monitoring consciousness, but BIS monitor is useful for evaluation of sedation level. Therefore we investigated whether BIS monitor is useful for this surgery.

Methods: Sixty-four patients scheduled for oral implant surgery were analyzed retrospectively.

Morphohistological change and expression of HSP70, osteopontin and osteocalcin mRNAs in rat dental pulp cells with orthodontic tooth movement.

Morphological change and expression of osteopontin, osteocalcin, and HSP70 mRNAs in rat dental pulp cells with experimental orthodontic tooth movement were investigated. Elastic rubber blocks, 0.65 mm in thickness, were inserted between the maxillary first and second molars in rats.
