Evaluation of New Bone Formation and Osseointegration Around Subperiosteal Titanium Implants with Histometry and Nanoindentation.

Purpose: To assess the quality and quantity of newly formed bone around rough-surfaced titanium subperiosteal implants stabilized with two different fixation techniques and to investigate nanoindentation as a method for measuring the elastic properties of the bone around these implants.

Materials And Methods: Ten 6-month-old white rabbits were used in this study. One femur received a subperiosteal implant fixed to the bone with screws.

The effect of permanent grafting materials on the preservation of the buccal bone plate after tooth extraction: an experimental study in the dog.

Objectives: The aim of the present study was to evaluate the effects of a novel bone substitute system (Natix(®)), consisting of porous titanium granules (PTG) and a bovine-derived xenograft (Bio-Oss(®)), on hard tissue remodelling following their placement into fresh extraction sockets in dogs.

Material And Methods: Six modalities were tested; Natix(®) granules with and without a covering double-layered Bio Gide(®) membrane; Bio-Oss(®) with and without a covering double-layered Bio Gide(®) membrane; and a socket left empty with and without a covering double-layered Bio Gide(®) membrane. Linear measurements, indicative of buccal bone height loss, and an area measurement indicative of buccal bulk bone loss were made.
