Background: Evidence shows lower chance for osseointegration of implants without sufficient primary stability. The present retrospective study observed bone level conical screw implants with textured surface without primary stability.

Methods: Twenty-six Stark conical screw implants, with V-Blast (Vanish Blast) surface treatment were placed with low primary stability, (insertion torque lower than 10 N/cm and visible mobility at lateral load of 250 g).

A doxycycline-treated hydroxyapatite implant surface attenuates the progression of peri-implantitis: A radiographic and histological study in mice.

Department of Oral Implantology and Regenerative Dental Medicine, Graduate School of Medical and Dental Sciences, Tokyo Medical and Dental University, Tokyo, Japan.

Background: Oral rehabilitation with dental implants has become increasingly common; however, the increase of peri-implantitis is a great concern. Doxycycline (DOX) is a widely used antibiotic that inhibits bacteria growth, inflammation, and bone resorption.

Objectives: To evaluate the progression of peri-implantitis of hydroxyapatite (HA)-coated implants with (5 mg/mL, DOX group) or without (HA group) DOX treatment on the surface.

Purpose: Application of endosseous implants in prosthetic orbital reconstruction seems to be very successful, but few reports have evaluated cumulative survival rates of orbital implants over a long period. The aim of this study was to analyze long-term survival rates and potential influencing factors of orbital implants.

Materials And Methods: A retrospective evaluation of patients treated with extraoral screw implants for retaining orbital prostheses from 1991 to 2014 was performed.

Trabecular deformations during screw pull-out: a micro-CT study of lapine bone.

Materials in Medicine Group, Division of Applied Materials Science, Department of Engineering Sciences, Uppsala University, Uppsala, Sweden.

The mechanical fixation of endosseous implants, such as screws, in trabecular bone is challenging because of the complex porous microstructure. Development of new screw designs to improve fracture fixation, especially in high-porosity osteoporotic bone, requires a profound understanding of how the structural system implant/trabeculae interacts when it is subjected to mechanical load. In this study, pull-out tests of screw implants were performed.
