By. HEAD OF DEPARTMENT. Dr. Rashid Hassan. Assistant professor. R.I.H.S. ISLAMABAD. 1. DENTURE BASE MATERIALS. Denture base materials can be divided into two types.. 1. METALLIC DENTURE BASE:. Gold alloys, cobalt chromium alloys.. Dr. lakshya kumar. Asstt. Professor. Deptt of Prosthodontics. Lecture-9 am to 10 am. 20/9/2014. PART 2, 3. Conventional heat cure acrylic resins. Conventional cold cure acrylic resins. High impact resistant acrylic resin. Dr. lakshya kumar. Asstt. Professor. Deptt of Prosthodontics. Lecture-9 am to 10 am. 20/9/2014. PART 2, 3. Conventional heat cure acrylic resins. Conventional cold cure acrylic resins. High impact resistant acrylic resin. Rola. M. . Shadid. , BDS, . MSc. The denture base supports the artificial teeth and consequently receives the functional forces from occlusion & transfers functional forces to supporting oral structures. SHOULD NOT EXCEED THE LEVEL OF PHYSIOLOGICAL TOLERANCE. BIOMECHANICS (GPT 7): . 1. : the application of mechanical laws to living structures, specifically the . locomotor. systems of the body. 2: the study of biology from the functional viewpoint . (stress equalizers). In the distal extension RPD support is derived from both the residual ridge and abutment teeth. The variation in consistency providing this support allows some rotational movements of the free-end base towards the soft tissues. Dr. . Sunit. . Jurel. . Assistant Professor. . Dept.Of. .

Denture stomatitis is a candidiasis (fungal infection) that occurs only beneath a denture. It can be asymptomatic or symptomatic causing a burning sensation, discomfort and bad taste. . Rola. M. .

The denture base supports the artificial teeth and consequently receives the functional forces from occlusion & transfers functional forces to supporting oral structures. 6-materials (metal and plastic) are verysatisfactory.There are two types of RPD denturebases: (1) metal, and (2) plastic.THE METAL DENTURE BASEThe metal denture base (Fig. 6-1) hasmetal in contact wi  . a) . methacrylate.  . b) . ethylmethacrylate. c) . metyl. ethyl . methacrylate. d) . polymethylmethacrylate. 2)If curing occurs at temperature more than 100 degree . celsius. porosity results in which are of denture.
