Thesis: It is shown that there are different types of removable partial dentures that are indicated in several cases in dentistry to restore missing teeth in order to avoid the harmful consequences on the oral tissues.
I- After teeth loss, several consequences occur if the teeth are not replaced.
A. Drift and Over eruption
B. Changes in muscle and joint function
C. Tooth wear
D. Loss of occlusion
II- Form and shape of partial dentures are actually a lot , so we need a classification to divide them and determine their types.
A. Kennedy classification
1. Class I Bilateral free-end
2. Class II Unilateral free-end
3. Class III Unilateral Bounded
4. Class IV Anterior (crossing Midline)
B. Classification by support
III- It is very important to know when a partial denture is indicated and when it isn’t.
A. Number of distribution of missing teeth
B. Status of potential abutment
C. Soft tissue Loss
D. Anterior tooth spacing
E. Restoration of occlusal face height
F. Patient preference and cost
IV- Partial dentures posses certain advantages for the patient.
V- Disadvantages of the removable partial dentures still exist.
VI- Conclusion
Restoration of the missing teeth occupies a major part in dentistry. Throughout the years several ways have been discovered to restore the

The act of chewing depends on the muscle and joint movements which occur subconsciously, however the loss of teeth can disturb the subconscious movements leading to disturbed chewing. Tooth wear and loss of occlusion are other consequences stated by Tyson et al. Tooth wear occurs rapidly in case of missing teeth as tooth loss concentrates the wear on the remaining tooth surfaces. Finally, loss of occlusion happens as the loss of several teeth disturbs the normal relationship between maxilla and mandible due to disturbing the normal intercuspal position.
Tooth surfaces are referred to by various names in dentistry, including mesial, distal, buccal, and lingual. If you drew a midline t...
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
This is done using the branch of dentistry called prosthodontics which establishes the goals of dentistry by replacing the missing teeth and oral and maxillofacial tissues with artificial substitutes. Prosthodontics is either removable prosthodontics or fixed prosthodontics. Fixed prosthodontics is the branch
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.
A partial denture is a removable appliance constructed by a dentist to replace missing teeth. Partial dentures are used in an area of the mouth where fixed, non-removable appliances are neither practical nor feasible. Constructing partial dentures takes approximately one to four visits depending on the type of appliance chosen. The dentist recommends the partial denture options best suited to his patient's aesthetic, functional and financial needs.
3) Describe the rationale and demonstrate how to chart existing restorations (amalgam, composite, gold, crowns, bridges, other), missing teeth, incipient caries and caries.
Two types of dentures exist today. The first are complete dentures. They’re used when you’re missing all of your teeth. The second is partial dentures,
To normalize the class III misalignments, the best treatment option is to retrocline mandibular incisors until a positive overlap maintains. The malocclusion was treated with pre-adjusted (0.022 slot) brackets and leveling and alignment using a round 0.014 and 0.016 inch nickel-titanium archwire and a rectangular 0.016 × 0.022 inch nickel-titanium archwire. To align mandibular incisors, 2.5 mm interproximal reduction was performed at 5 anterior contacts (0.5 mm/contact). A rectangular 0.016 x 0.022 inch stainless steel archwire with lingual crown torque on the mandibular incisors was used to retrocline mandibular incisors. To correct the unilateral posterior crossbite, the cross elastics were used to uncross a group of teeth. For finishing, a rectangular 0.019 x 0.025 inch stainless steel archwire was used. After the active treatment phase, wraparound retainer was used for the maxilla and 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...
Humans only get one set of adult teeth after losing all of their primary teeth therefore, it is important to take care of them. “Dental caries: Strategies to control this preventable disease” is an article written by Rugg-Gunn, Andrew presents several reasons why dental decay is a widespread disease. Rugg-Gunn cites that the main cause of dental decay is lack of fluoride, poor diet, bacteria from plaque, and sugars. Based on this evidence, Rugg-Gunn concludes that “dental caries can be prevented” (Rugg-Gunn128), but there is no evidence of stopping the disease from happening. While Rugg-Gunn raises a revolving problem around the world with human oral decay he however, does not have a good approach on what decay really is.
Stoll, Betke et al. (2005) In a retrospective study estimated that the survival according their apical extent. Flush fillings had a 94% survival estimation while short and long fillings estimated results were 80.9% and 74.0% respectively in 5 to 10 years.(Caplan and Weintraub 1997) in a case control study found similar results but it was insignificant. They also found that teeth which had long fillings were extracted rather than retained in contrast to short filling which were retained more often than extracted. The previous results show that RCT within 2 mm of the radiographic apex have the best outcomes.
The gum tissue begins pulling away from the teeth. This creates pockets that allow bacteria to build up, which leads to an infection. As your body fights the harmful bacteria, the bone and tissue holding the teeth in place begin breaking down. The pockets deepen and begin filling with pus. Once you reach this stage, you may need to have surgery to save your teeth. If not treated, the infection begins destroying the bone around the teeth. If the bones, tissue and gums supporting your teeth are destroyed, the teeth may begin to shift, loosen and/or fall out.
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
Getting a good oral health can show the condition of body and reduce the getting other diseases in our body. Some reports have shown that periodontal disease has a relationship with a stroke, heart disease. Pregnant with periodontal disease also get a higher chance having low birth weight babies. Oral infections are the symptoms of some of the diseases. (U.S. Department of Health and Human Services, 2000)Furthermore, a survey found that the dental decay and poor oral hygiene are the potential risk factors of having pneumonia. Also, a better oral health can reduce the occurrence of pneumonia. (Azarpazhooh & Leake, 2006) Maintaining oral health not only a matter of oral, but also related to our health of whole body. In addition, people with loss of tooth may not chew food enough, which may cause the digestive problems of digestive system. People may not underestimated the importance of maintaining good oral hygiene.
One last very severe effect of smoking is teeth decay. The reason for teeth decay is tobacco products which damage your gum tissue by affecting the attachment of bone and soft tissue to your teeth. An example of the effect is receding gums. A receding gum line exposes the tooth roots and increases your risk of developing a sensitivity to hot and cold, or tooth decay in these unprotected areas. Additionally, smoking can also contribute to bad breath, stains in the teeth and a build-up of tartar on the teeth.
