## Abstract Achieving solid skeletal attachment is a requirement for the clinical success of orthopedic implants. Porous or roughened surfaces and coatings have been developed and used with mixed success to achieve attachment due to bone ingrowth. Silicon nitride is a high performance ceramic whose

Abstract
Experiments have been devised to study the rate of ingrowth of bone into porous metal with pore sizes up to 100 ΞΌ and to study the significance of a gap between the porous metal surface and bone.
When the porous coat was in direct apposition with bone, the implant was firmly locked in place after a three week period and the plateau value of implanttissue shear strength was reached at four weeks. A gap of 1.5 mm between the bone and the implant was bridged by new bone wihtin four weeks.

## Abstract A preliminary investigation has been performed (a) to determine the kinetics of bone ingrowth into porous materials and to determine if this ingrowth could be catalyzed by the presence of a foreign substrate; and (b) to measure the bonding capability of bone with a porousβsurfaced metal
## Abstract Research to determine whether porousβcoated Vitallium intramedullary rods could be used to bridge segmental defects in long bones was performed using rabbit tibias as a suitable model for human bone growth. Oneβcentimeter segments of the midshaft of tibias of mature rabbits were removed
Porous hydroxyapatite, converted hydrothermally from the calcium carbon exoskeleton of the coral genus Goniopora (CHAG), has been shown to be effective as a scaffold for bone ingrowth (2,3,(5)(6)(7)9). However, the large pores in the material resulted in low compressive strengths. In a previous stud
This study sought to quantify bone ingrowth from a single bone-implant surface into porous block hydroxyapatite used in maxillofacial applications. Seventeen maxillary hydroxyapatite implants (implant time of 4-138 months, 39-month mean) were harvested for analysis from 14 patients. The implants had
## Abstract Previous investigations have shown that both the early biological response and the mechanical properties of a porous hydroxyapatite bone graft substitute are highly sensitive to its pore structure. The objective of this study was to evaluate whether the pore structure continued to influ
