 Pre-Clinical Removable Prosthodontics (Complete Denture)  Please; Mobile Phones should be silent & Take Notes  Terminology Prosthetics: It is the art and science of supplying, fitting and servicing artificial replacement for missing parts of the human body. Prosthesis: It is the replacement of a missing part of the human body by an artificial part e.g. eye, leg or arm prosthesis.  Prosthodontics or Prosthetic dentistry: It is that branch of dental art and science that is concerned with restoration and maintenance of oral function by replacement of missing teeth and surrounding structures by artificial devices Terminolo gy Dentulous: It is a condition in which all natural teeth are present in the oral cavity. Edentulous: It is a condition in which natural teeth are absent in the oral cavity. Partially edentulous: It is a condition in which some of the natural teeth are absent in the oral cavity. Completely edentulous: It is a condition in which all of the natural teeth are absent in the oral cavity.  Complete Denture: It is a dental prosthesis that replaces the entire natural dentition and its associated structures of the mandible and/or maxilla. Partial Denture: It is a dental prosthesis that replaces one or more, but not all, of the natural teeth and its supporting structures and is supported by teeth and/ or mucosa. It may be fixed or removable. Immediate denture: It is a dental prosthesis that is constructed before extraction of teeth and Complete Denture Partially edentulous Partial Denture Immediate Denture COMPLETE DENTURE Definitions : “A prosthesis that replaces the lost natural dentition and associated structures of the mandible and / or the maxilla “.  Complete Denture Component Parts 1- Denture Base 2- Artificial teeth Denture base: It is that part of the denture that rests on the tissue foundation and carries the artificial teeth. Denture base: A- Denture border: It is the margin of the denture base at the junction between the polished and the impression surface. B- Denture Flanges: The vertical parts of the denture base that extend from the cervical margin of the teeth to the borders of the denture are called denture flanges. They are named according to their location  Denture Flanges: Buccal flange: the portion of the denture that is related to the cheek and occupies the buccal vestibule. Labial flange: the portion of the denture that is related to the lip and occupies the labial vestibule. Lingual flange: the portion of the mandibular denture that is related to the tongue and occupies the lingual sulcus.  Denture Surfaces Polished Surface Occlusal Surface Fitting Surface  Denture surfaces: 1Polished surface: the denture surface that carries the artificial teeth. It includes the facial, lingual and palatal surfaces facing the cheeks, lips and tongue. 2Occlusal surface: the denture surface that makes contact with its antagonist. 3Fitting surface or impression surface: the denture surface that has its contour determined by the impression. 3 3  Denture border: It is the margin of the denture base at the junction between the polished and the impression surface. Objectives in complete denture construction: Steps of Complete Denture Constructiion Complete denture is the outcome of several steps. Some of these steps are clinical (i.e done in the clinic in the presence of the patient) and others are laboratory (i.e. done in the laboratory in the absence of the patient). CLINICAL AND LABORATORY STEPS FOR C.D.
