Abutment Teeth

A bridge is considered radical treatment as adjacent tooth structure must be drastically reduced in this process. The bridge has been regarded as the standard of care for some time in the replacement of single and multiple missing teeth. However, in order to obtain optimal functional and aesthetic results for full-veneer bridges, a significant reduction in the amount of tooth structure is necessary, occasionally predisposing to endodontic, periodontal, and structural complications. The abutment teeth often become carious and thus have an increased rate of those individuals needing a root canal procedure. If one of the abutment teeth are lost a longer span bridge would be required. The implant procedure is more conservative and has a better prognosis. Implants have a high rate of success, do not require procedures on adjacent teeth and are not susceptible to caries.

In a study of 34 patients aged 75 years or over who depended on assistance for daily living activities, patients were randomly assigned to receive two mandibular implants to support an overdenture or a relined conventional mandibular denture. In the patients who received the mandibular implant overdenture treatment, an increased oral health-related quality of life was reported; however, chewing efficiency was no different between the groups. The insertion of the mandibular implant overdenture was noted as problematic for some patients and their caregivers due to the nature of the Locator attachments, and in two cases the attachments were replaced by attachments that permitted easier insertion . This is an important consideration for

Implant overdentures have contraindications, mainly in relative to the risks related to the surgical procedures, even if in specific cases it can be regarded as a minimally invasive one. Additionally, using this specific treatment concept is limited to cases with reduced prosthetic vertical space that makes it impossible to apply the attachment systems and also provide adequate prosthesis resistance (e.g., using Locators requires a minimum of 8.5mm vertical space and 9mm horizontal space; bar attachments require 10 to12 mm vertical space) .Implant overdentures are not recommended when there is a decreased D4 bone density, in bruxism and in severe oral hygiene deficiency.

This patient’s periodontal exam reveals probing depth for number 5 is 4mm. This could be sign of localized gingiva or inflammation of swollen gingiva can increase the probing depth. Furthermore, the possible reasons for her recurrent caries are incomplete removal of caries before endodontic treatment, improper marginal sealing of crown, improper sealing of root canal, and improper flossing between the teeth. Unfortunately, number 5 cannot be restored from the damage she has. Several options can be considered to resolve her chief complaints. The first option is the implant. The implant sounds like a great option for her. But, her dental cast reveals that her teeth space between 5 and 7(12mm)are too narrow to have the implant. (shah 2008) The second option is making the Pontiac bridges between numbers 4 to 7. But, This is not a good considerable option because her sound teeth must be damaged to build the bridge between numbers 4 to 7. The last option is the partial denture. The partial denture is a great option for her because it is affordable and able to maintain sound teeth. Therefore, partial denture is probably the best option to resolve her chief

Placement of a removable prosthesis in the oral cavity produces significant changes in the oral

Of course, when dealing with artificial teeth in complete dentures, many will be terrified of the idea of their future artificial appearance and will think restoring old natural appearance is impossible, but they have no idea that removable prosthodontics is the art branch of dentistry, and that it has in its dictionary what we call “ Denture esthetics: the cosmetic effect produced by a dental prosthesis which affects the desirable beauty, attractiveness, character, and dignity of the individual. “

Like most of my colleagues, I entered dental school unsure of specialty choice. It then motivated me to seek opportunities in various internship and externship programs to explore the many facets of dental medicine. Upon graduation from dental school, I attended the Eastman Institute for Oral Health of the University of Rochester, where my curiosity and interest in endodontics arose. Through various lectures and hands-on workshops on endodontics and microscopic dentistry, I was amazed and intrigued by the intricate and precise aspects required in the field of endodontics. I have also come to further appreciate the importance of preserving the integrity of a natural dentition.

Dental implants have evolved immensely over the past 20 years. However, the concept of a tooth replacement implant is not new. From the existence of societies, the importance of beauty and retaining of one’s teeth have been of upmost importance. Having a full set of nice teeth has been essential in appearance and the main contributor to being perceived attractive. This is because a person’s smile is one of the first things other people notice. The idea of permanently being able to replace teeth has been a desire of civilizations since the earliest days. Archaeological evidence shows that man has been trying to overcome periodontal problems and tooth loss for thousands of years. Fortnightly, our modern-day methods of dental implantation are much more successful and painless than the attempts from 4,000 years ago.

Chronic periodontitis is a complex disease that is mainly caused by intraoral biofilm harbouring periodontal pathogenic microorganisms. This results in progressive destruction of periodontal ligament and alveolar bone with pocket formation, recession or both. Hence the goal of periodontal therapy is to eliminate these pathogenic organisms in the subgingival biofilm to achieve homeostasis. Non-surgical periodontal therapy is the keystone and first mode of treatment recommended for most periodontal infections. However, this treatment protocol does have limitations. Although the bacteria are initiating agents in periodontitis, the host response to the pathogenic microorganisms is critical to disease progression. The adjunctive use of systemic

If you are living without teeth — or have been recently informed of your upcoming extraction procedure — dentures may be for you. Our traditional removable dentures are designed to completely replace an entire arch of teeth, or in many cases, an entire mouth. We craft beautiful, lifelike crowns that are set into a plastic, gum-colored mold. This mold sits directly over your gums and is designed to fit comfortably and securely. Our traditional dentures are a time-tested tooth replacement solution.

The dental implants have completely changed the foundation of the oral rehabilitation due to their well demonstrated success rates(95%) and high predictability (Esposito et al,2011).As an increasing number of people are receiving implants2,9,10,11,12,13,14 ,there has been ,simultaneously ,a growing interest in identifying the components that can predispose individuals to lower rates of success and cause a significant loss to both the dental practitioner and the patient14,17,18.Broadly ,these factors may be classified as ;patient, clinician or implant associated15,16.

-. Complete denture wearers often complain about decreased bite force, mobility, retention-stability problems and pain . In addition, masticatory performance, treatment success, patient satisfaction, and oral health related quality of life are significant features in prosthodontic treatment .

The primary reason for performing endodontic therapy is the preservation of teeth and preventing their loss. However, endodontic treatment renders them more susceptible than vital teeth to biomechanical failure because of the access preparation. (1; 2)

This essay will begin with a brief overview on chronic periodontitis to better facilitate the proper selection of abutment in patients with a history of the disease. Chronic periodontitis is a slowly progressive inflammatory disease that results in the destruction of periodontium, characterised by clinical attachment and alveolar bone loss (Armitage and Cullinan, 2010, Shaddox and Walker, 2010). For a patient with a history of chronic periodontitis,

There are two main theories relating to orthodontic tooth movement, which are crucial to understand the assessment of the ‘ideal’ force for tooth movement. The bone-bending theory, otherwise referred to as the biological electric theory, proposes that forces applied to teeth stimulate electron release, which are then involved in remodeling alveolar bone. Possibly more accepted, however, is the pressure-tension theory. This theory suggests that forces applied to a tooth result in compression of the periodontal ligament on one side of the root, and a tension force applied to the other. Compression for an extended time, exceeding approximately four hours, results in a release of chemical mediators, including prostaglandins and cytokines, in addition to decreased oxygen associated with reduced blood flow. These mediators act to directly, and indirectly through secondary messengers
