Since the dawn of humanity, humans have always had issues with their teeth. Dentists have always worked hard to fix these problems and assure optimum dental health and esthetics. The science of dentistry has many divisions. Prosthodontics is a branch of dentistry which studies the replacement of missing teeth and its related structures by the use of artificial appliances to restore and bring back the normal esthetic and masticatory functions. Prosthodontics also has many subdivisions which are: fixed, removable and maxillofacial Prosthodontics. Removable Prosthodontics is divided into complete denture Prosthodontics dealing with completely edentulous patients who lost all their natural teeth and partial denture Prosthodontics dealing with partially …show more content…
Advanced technologies have been discovered for repairing the distorted metal framework of the removable partial denture such as the laser welding technology which has had an effective role in fixing the framework by soldering techniques. There are two types of welding which are conduction and spot welding, spot welding is the most commonly used type especially when it comes to the laboratory procedures. There are some conditions that must be done and taken into consideration to achieve efficient welding such as the area being welded, the depth of welding and the intimate contact between objects being welded together. There are different types of lasers, the type of alloy being welded determines the specific type of laser needed for welding this specific alloy.(6) In conclusion, the process of fabricating a removable partial denture from scratch is a long, complicated and detailed process. There must be complete harmony between the dentist and the technician to produce a perfect partial denture. Talbot (7) stated “The laboratory authorization requires detailed instructions. Framework evaluation and subsequent placement necessities adherence to basic prosthodontic principles”
Tooth surfaces are referred to by various names in dentistry, including mesial, distal, buccal, and lingual. If you drew a midline t...
Professionalism in the dental profession refers to our responsibilities and obligations that exists throughout our entire dental career. “Professional competence is the habitual and judicious use of communication, knowledge, technical skills, clinical reasoning, emotions, values and reflection in daily practice for the benefit of the individual and community being served (Kirk, 2007).” A health professional must be able to regulate their own behavior and comply with a code of ethics in professional practice. Fundamental principles of professionalism include primacy of patient welfare, social justice and patient autonomy (Kirk, 2007).
Our team offers removable dentures to patients needing to replace some or all of their natural teeth. Our dentures are custom-designed for a secure fit. We offer both complete denture and partial denture options to meet your specific
In each case they started by extracting the remaining teeth in one jaw and examined clinically and radiographically to make sure root canal treatment can be made and that there is periodontal support available for the denture. After root canal treatment was made, they were sealed with amalgam and topical fluoride, then the application of gold copings. Finally the process of gingivectomy takes place. After all these steps the denture is ready for construction. After construction, relief of the fitting surface of the denture is made. The dentures were delivered to the patients and were ready for use.
The biggest shortcoming of these archaic appliances was the fact that they were subject to decay in the wearer’s mouth. Thus, installed false teeth would have to be replaced on a regular basis, resulting in a very costly procedure. However, this problem was rectified in 1774 by Duchateau and Dubois de Chemant with their invention of the first full set of dentures that would not rot. This was due to their porcelain composition – a material that was much more conducive to the everyday wear and tear of one’s teeth. Although an incredible improvement, even the porcelain version had its difficulties. Unable to produce anything less than a full set of teeth (the surrounding porcelain was required to keep each tooth in place), patients who were missing only one or two teeth were out of luck, unless they were willing to have the rest of their teeth removed as well. And yet, in 1808, Giuseppangelo Fonzi developed the first individual appliance – a single porcelain tooth that could be held in place by a pin drilled into the jawbone. Finally, in 1845, Claudius Ash, known as the official “inventor of dentures”, produced the porcelain version that is now used today. His contributions included a suction method of adhesion for a full set of dentures, so that no form of attachment could be seen by an onlooker.
Adhesion of resin materials to tooth structure has been a challenge in the history of adhesive dentistry. Currently, bond durability is one of the main research topics in adhesive dentistry. Regardless of the improvements in bonding technology, resin dentin bonds show limited durability for both etch and rinse and self-etch adhesive systems.
Disease Incidence: The number of decayed, missing, and filled surfaces that occur over a given period of time. Two different examinations are required to determine incidence- one before, and one at the end of a selected time period.
Research on application of laser in dentistry began when Ralph H Stern & Reider F Sognnaes1(1963) of Los Angeles School of Dentistry, University of California studied thermal effect of ruby laser on dental hard tissues & restorative materials. Since then there had been attempts to utilize the benefits of laser in each and every field of dentistry. Laser may be used in dentistry effectively for their ability to incise, cut and ablate soft and hard tissues. In 1965, Leon Goldman first reported the case of laser exposure to a vital human tooth2.
After the treatment and procedure is complete, patients leave with healthier, more beautiful teeth, giving them the confidence to ask someone out on a date or the confidence to smile on an important job interview. Dentistry is and has been for centuries, an important aspect of people’s ...
Dentures are removable teeth. They’re used for replacing missing teeth and their surrounding tissue. Due to their important role in your mouth, understanding broken denture repairs is also important.
The contraction moulding method can be used to process an acrylic denture base. In this method, bite blocks are fabricated in the lab and sent to the clinic for patient trial. These are then received from the clinic and teeth are mounted onto the bite blocks. The wax is eliminated and teeth are pressurized and attached onto a gypsum mould. (McCabe and Walls. 2008.) Sodium alginate is applied onto the mould to act as a separator to prevent any monomer from the acrylic base seeping into the base and the mould. Acrylic PMMA is applied onto the mould and either heat-cured or auto-polymerized. Both of these curing methods form the...
Abnormal wear of tooth surfaces was an orthodontic problem early on, even ancient people wanted straight teeth! To close gaps, it has been construed that catgut did the work now done by today’s orthodontic wire. In 400-500 BC, Hippocrates and Aristotle both ruminated about ways to level teeth and fix many dental conditions. It should be noted that in Medieval times, expert barbers often performed dental “operations”, extractions, and procedures such as blood-letting. In seventeen twenty-eight, French Dentist Pierre Fauchard published a book called “The Surgeon Dentist” about ways to straighten and align teeth. He used a device called a “Bandeau,” a horse-shaped piece of precious metal which helped...
Impression materials are used to register or reproduce the form and relations of the teeth and the surrounding oral tissues (1). Making an impression represents a critical step in processing and fitting of a dental prosthesis (2). Several types of impression materials are produced. These include silicones, polyether, polysulfide and alginate which are available for crowns and fixed partial denture impressions. Silicone impression materials are considered to be suitable impression materials to use for fixed prostheses (3). Also, it has been reported that silicone has the ability to remain dimensionally stable through disinfection procedures (4). Among silicone impression materials, one type of them, called polyvinyl siloxane (PVS) is reported
Cosmetic dentistry is a specialized field that deals with improving the aesthetics of teeth and the human face. The teeth are an important part of human beauty. Even minor damage to the teeth, such as breakage or loss can drastically alter the overall appearance of the face. This is where cosmetic dentistry comes in to restore beauty. Cosmetic dentistry has become a highly specialized branch due to various advancements in surgical procedures and diagnostic techniques. Several new materials have also been discovered. These materials are very close to the natural enamel and bone from which teeth are made and are virtually indistinguishable. Cosmetic dentistry is an option in conditions such as teeth loss, gaps between teeth, cracked or chipped teeth, cavities and dental
In the past, diseased or damaged teeth could not be salvaged and in most cases, had to be pulled out. However, in the last three decades, endodontic dentistry has evolved to quite an extent and today, professionals trained in this specialty can help save teeth and repair any inherent damage. Common endodontic procedures include root canal therapy, fixing of broken teeth and repairing dental trauma.
