Prosthodontics is a branch of Dentistry pertaining to the restoration & maintenance of oral function, comfort, appearance & health of the patient by the restoration of lost teeth and or replacement of missing teeth & craniofacial structures with artificial substitutes.
The Department of prosthodontics at St. Joseph Dental College,teaches and trains undergraduate students about basic preclinical and clinical prosthodontic procedures involved in removable and fixed prosthodontics.Department also offers three years Postgraduate programme leading to a Master of Dental Surgery awarded by the Dr. NTR University of Health Sciences, Vijayawada, AP, approved and accredited by the Dental Council of India. MDS programme involves advanced training in all the preclinical and clinical aspects of prosthodontics with research orientation and adapting to latest developments and advancements in the field of prosthodontics.
The department of Prosthodontic deals with a wide array of problems encountered by patients such as complete and partial loss of teeth, Jaw joint problems, loss of craniofacial structures and are treated using modalities such as complete dentures, removable partial dentures, Fixed prosthesis, Maxillofacial Prosthesis and implant supported prosthesis. The current focus today is on preventive and digital prosthodontics and the research projects Carried out in our department are focused on the latest developments in the field of dental materials, dental implants and concepts and techniques involved in Prosthodontics.
Mission: To be centre of excellence in the field of prosthodontics and implantology and one of the leading department in the country imparting patient education and problem-solving skills to budding prosthodontists .
Vision: To provide high quality, affordable and advanced dental care to patients with high ethical standards. To provide continuous high quality value based education, advanced training facilities to students. To emerge as a center for digital laboratory facilities, advanced equipment and competent faculty for quest of excellence.
Goals of the Department
The goal of prosthodontics programme is to provide basic & advanced education in prosthodontics for an improved understanding of prosthetic rehabilitation & restoration of tooth structures.
- To increase cognitive skills in management of geriatric & general patients
- To transform the nature of dental education in a way that will dramatically improve the way we serve our students, our patients& the surrounding community.
Teaching Program
The educational programmes in Prosthodontics are extensive &involves various programmes for under graduate students, house surgeons& Post Graduate students.
Undergraduate Education in Prosthodontics for Dental Students
This program provides lectures and practicals for under graduate students. We teach dental materials and preclinical prosthodontics to 1st and 2nd year students where they learn about all preclinical procedures invoved in fabrication of removable and fixed prosthesis. 3rd year students will be trained on patients for fabrication of removable partial dentures and final year students will be trained on patients for fabrication of removable complete dentures. During internship we teach them basic clinical steps involved in fabrication of fixed partial dentures and overall management of patients.
Postgraduate MDS Program in Prosthdontics
The programme requires a minimum of three academic years for completion. The goal of Prosthodontics MDS programme is to provide advanced training in prosthodontics to qualified dental graduates.
The programme devotes a considerable portion of time to advanced basic science course specially organized to serve as a prerequisite to the thorough understanding of the clinical problem in prosthetic rehabilitation. Post graduate studentsare exposed to different & challenging maxillofacial & prosthetic rehabilitation cases through independent study demonstration & practice.
The course also involves development of technical skill involving handling of sophisticated & technique sensitive equipments
A series of seminars, lecture course and CDE programmesconducted to learn the latest developments in the field of prosthodontics.
Research work to improve the out come of prosthetic treatments will be taken up by the Post graduate students.

DENTAL MATERIALS
AIMS:
Aim of the course is to present basic chemical and physical properties of Dental materials as they are related to its manipulation to give a sound educational background so that the practice of the dentistry emerged from art to empirical status of science as more information through further research becomes available. It is also the aim of the course of Dental materials to provide with certain criteria of selection and which will enable to discriminate between facts and propaganda with regards to claims of manufactures.
OBJECTIVES:
- To understand the evolution and development of science of dental material.
- To explain purpose of course in dental materials to personnels concerned with the profession of the dentistry. Knowledge of physical and chemical properties. Knowledge of biomechanical requirements of particular-restorative procedure. An intelligent compromise of the conflicting as well as co-ordinating factors into the desired Ernest. Laying down standards or specifications of various materials to guide to manufacturers as well as to help professionals.
- Search for newer and better materials which may answer our requirements with greater satisfaction. To understand and evaluate the claims made by manufactures of dental materials
NEEDS FOR THE COURSE:
The profession has to rise from an art to a science, the need for the dentist to possess adequate knowledge of materials to exercises his best through knowledge of properties of different types of materials. The growing concern of health hazards due to mercury toxicity, inhalation of certain vapour or dust materials, irritations and allergic reaction to skin due to contact of materials. Materials causing irritation of oral tissues, pH of restorative materials causing inflammation and necrosis of pulp which is a cause for the dentist to possess wider knowledge of physical, chemical and biological properties of materials being used. For the protection for the patient and his own protection certain criteria of selection are provided that will enable the dentist to discriminate between facts and propaganda, which will make a material biologically accept.
SCOPE:
The dental materials is employed in mechanical procedures including restorative dentistry such as Prosthodontics, endodontics, periodontal, orthodontics and restorative materials. There is scarcely a dental procedure that does not make use of dental materials in one form or another and therefore the application of dental material is not limited to any one branch of dentistry. Branches such as minor surgery and periodontics require less use of materials but the physical and chemical characters of materials are important in these fields.
The toxic and tissue reaction of dental materials and their durability in the oral cavity where the temperature is between 32 & 37 degree centigrade, and the ingestion of hot or cold food ranges from 0- 70 degree centigrade. The acid an alkalinity of fluids shown pH varies from 4 to 8.5. The load on 1 sq. mm of tooth or restorative materials can reach to a level as high as many kilograms. Thus the biological properties of dental materials cannot be separated from their physical and chemical properties.
