The clinician may therefore have difficulties deciding which treatment option to choose to resolve complex situations of advanced tooth wear. A systematic review 5 of treatment options for tooth wear reports that the present evidence is not strong enough to form conclusions. Testing of the OVD increases with a removable appliance and the use of a provisional stage before definitive treatment is recommended. 1,2,4, The dental literature refers to Attrition, Abrasion and Erosion as terms to describe tooth wear, although these terms do not refer specifically to the descriptive process of tooth wear. Nasal Prosthesis 8. Retention and resistance forms require minimal clinical crown heights for full coverage restorations. Although there could be a dominant factor causing severe wear of a dentition, one can easily understand that a patient suffering from moderate gastric reflux in combination with para-functional bruxism would potentially suffer from a more rapid rate of wear than another patient that bruxes in the absence of any gastric reflux. The process involves a foreign object or substance repeatedly contacting the tooth. The Commission on Dental Accreditation of Canada (CDAC) reviews and accredits the education programs in the nine dental specialties in Canada. Support is the means by which occlusal forces are transferred to the teeth and denture bearing tissues for dissipation (Fig. 2000 Mar-Apr;13(2):101-7. A resistance arm is the part of a lever that moves against weight or resistance. Muts EJ, van Pelt H, Edelhoff D, Krejci I, Cune M. Tooth wear: a systematic review of treatment options. Treatment Planning Challenges Contemporary prosthodontic protocols integrate esthetic features of the smile and the face. It is critical to identify patients that are at risk or already showing signs of wear to initiate a discussion about the possible etiologies. The clinical outcome and presentation of the dentition describe the multifactorial underlying causes. Extensive tooth wear seems to have been the norm in ancient civilizations and the main attributed cause was coarse diet related. Prosthodontics) Reline : The procedures used to resurface the tissue side of a removable Dental Prosthesis with new base material, thus producing an accurate … As in complete denture therapy 11 where there is total loss of the dentition and periodontium, a comprehensive evaluation and treatment plan should include the role of tooth position, dimension, shape in relation to the facial appearance integrating symmetry, harmony and occlusal function. J Prosthet Dent. • Bacterial resistance to aminoglycosides aminoglycoside-modifying enzyme • β -lactam antibiotics β -lactamase 15. These older patients’ dentitions appear to have reached the “end” of their structural life span: a rather uncommon clinical presentation when life expectancy was merely 55 to 60 years. Early diagnosis, identification of the cause and regular monitoring enables initial prevention, management and timely initiation of adequate restorative treatment when required. Treatment sometimes requires an interdisciplinary approach including pre-prosthetic orthodontics, clinical crown lengthening, orthognathic surgery and programmed OVD increase. SUPPORT Resistance to vertical movement or displacement of the dentures towards the basal seat area 18. B. They typically include short teeth, lack of tooth display at rest and smile, darkened areas of exposed dentin on mandibular teeth, thin eroded enamel showing the underlying dentin and less frequently, altered irregular gingival margins. It is essential to choose material suitable for restoring the teeth of patients with gastroesophageal reflux in order to ensure longevity of the procedure, because contact with hydrochloric acid may be cause for superficial alteration in composite resin. Science of providing suitable substitutes for coronal portions of teeth, or for one or more lost or missing teeth and their associated parts, so that impaired function, appearance, and comfort, may be restored. There is no indication that permanent alteration in the OVD will produce long-lasting TMD symptoms. A Prosthodontist is a dentist specialized in the field of Prosthodontics, one of nine dental specialties recognized by the Canadian Dental Association (CDA) and the American Dental Association(ADA). Early stages of erosion affect enamel, resulting a shallow, smooth, glazed surface without ridges or stain lines. Implant Prosthodontics 7. This review presents a few guidelines and clinical implications. Category 3 patients are the most difficult because vertical space must be obtained to accommodate restorative materials. Fixed Prosthodontics - Tooth preparation guidelines for complete coverage metal crowns ... are made regarding preparation design for tilted teeth used as abutments for fixed partial dentures in order to enhance resistance form and retention form. Prevalence of Tooth Wear Sometimes called the architects of the smile, prosthodontists are highly trained specialists with a unique understanding of all the elements that go into a beautiful, functional and natural-looking smilenot just the teeth, but also the gums, lips, and facial features. When the entire dentition is severely worn requiring reconstruction of the occlusion with increased OVD in CR, a full mouth rehabilitation involving full coverage restorations would generally provide the most flexibility in achieving the predictable esthetics and function. Another important observation is the severity/rate of wear regardless of etiology. J Prosthet Dent. The composite restorations can eventually be replaced with porcelain restorations over time to complete treatment in a “segmented” fashion without compromising the ideal plane of occlusion, esthetics and function. Goodacre CJ. It is commonly assumed, without definitive evidence that extensive occlusal wear results in decreased OVD. See more. Support , is defined as the resistance to vertical f orces of mastication ,occlusal. Clinically, it is often difficult to clearly differentiate among erosion, abrasion, and attrition. Is Your Tongue Causing Your Health Problems? The design and preparation of a tooth for a cast… Prosthodontics deals with treatment and correction of defects by providing a pleasing appearance to the patient in addition to speech and mastication. 2004 Apr;48(2):v, 359-85. The Turkish Prosthodontics and Implantology Association e2 Volume 117 Issue 5S THE JOURNAL OF PROSTHETIC DENTISTRY. In today’s societies, it is extremely rare to find the severity of wear identified in historical remains. 1. There are situations where restoration of a worn dentition can only be accomplished predictably by increasing the OVD. Maxillary Central Incisal Edge position: this is evaluated at rest and in a full smile Comprehensive treatment planning should follow a well-sequenced approach that not only accounts for tooth wear but the overall esthetics and occlusion. In advanced erosion cases, restorations can project above the occlusal surfaces and the cusps/convexities/incisal edges show concavities know as “cupping.” Intrinsic causes (gstric acid reflux) of erosion affect the palatal surfaces of the maxillary teeth showing concave depressions. The esthetic concerns of patients are broad. Erosive lesions located on the palatal surfaces of the maxillary teeth as a result of chronic vomiting have been termed as perimolysis or perimylolysis.
