The Influence on Osseointegration of Immediate Functional Loading on Single Crowns: A Randomized, Double-Blind, Split-Mouth Controlled Clinical Trial with Histomorphometric Evaluation.

Purpose: To evaluate the influence of immediate loading on the osseointegration and bone density of implants placed in a healed alveolar bone crest and supporting single crowns.

Materials And Methods: Two solid titanium transmucosal miniimplants were placed in the distal regions of the mandible in 14 patients. One mini-implant was immediately functionally loaded, whereas the other was left unloaded.

Implant stability and marginal bone level of microgrooved zirconia dental implants: A 3-month experimental study on dogs.

Background/aim: The modification of implant surfaces could affect mechanical implant stability as well as dynamics and quality of peri-implant bone healing. The aim of this 3-month experimental study in dogs was to investigate implant stability, marginal bone levels and bone tissue response to zirconia dental implants with two laser-micro-grooved intraosseous surfaces in comparison with nongrooved sandblasted zirconia and sandblasted, high-temperature etched titanium implants.

Methods: Implant surface characterization was performed using optical interferometric profilometty and energy dispersive X-ray spectroscopy.
