1. Introduction

Presintered metal alloys are milled to larger size than final one using a soft-machining process, followed by sintering of the milled prosthesis [19]. Because the hardness is lower in the presintered alloys than in the fully sintered alloys, soft machining is more time- and cost-effective than hard machining for producing prostheses [18, 20].
