Resin-Bonded Bridges − the Problem Or the Solution?: Part 1 Assessment and Design RestorativeDentistry Jasneet Singh Gulati Sara Tabiat-Pour, Sophie Watkins and Avijit Banerjee Resin-Bonded Bridges − the Problem or the Solution?: Part 1 Assessment and Design Abstract: Resin-bonded bridges (RBBs) have an important role to play in the minimally invasive prosthodontic replacement of missing teeth. This treatment modality is perceived to have a high clinical failure rate by some practitioners, which may be associated with poorly planned and executed designs and adhesive techniques. This paper, the first part of a two-part series, discusses the important planning stages in the successful provision of RBBs, including assessment, appropriate abutment selection and design considerations. The second part of this series will focus on the clinical stages of RBB provision.

TSL includes all forms of loss of tooth material not due to disease of bacterial origin (ie. caries) and is usually considered to be: Attrition Abrasion Erosion Fractures Developmental defects Dentistry should also be added to the list as we as a profession often cut bits off teeth! Always look for it at patient examination using loupes (eg 3x magnification), bright light and dry teeth. Establish a diagnosis then formulate a plan. The TSL can be monitored using photographs, study models, indices or charts. Check these are dated. The general plan is to apply prevention, monitor and avoid restorative treatment where possible. Active intervention should be non-invasive where possible to prevent further tooth loss. Principles of management: 1.

The treatment of the patient with extensive tooth wear presents complex challengesenges, due to diagnosis of often a multi-factorial etiology, and the definitive manaanagement of the patient. Patients may seekeek dentald care to improve their esthetic appearance, without fully comprehendinding theth complexity or problems associated with tooth wear. Typical symptoms that patientsp present with include poor esthetics, chipping/thinning of teeth, dentinaldentin hypersensitivity, reduced occlusal vertical dimension, and minimal toothoth heihe ght. Historically the management of patients presentiting withw extensive tooth wear was with conventional fixed prosthodontics. This would involve preparation with crowns on the teeth where tooth structures wereere alreadyal compromised. This would increase the biomechanical risk to the dentitiontition due to the reduction of tooth structures, which negatively impact the structural rigidity of the teeth. Edelhoff and Sorenssen [1] found that 62% to 73% of tooth structure can be removed undertaking the preparation to receiveceive either a full coverage all-ceramic crown or porcelain fuseded to metal crown. Additionally a conventional approach could result inn a losslo of pulpal vitality of the teeth. Teeth requiring fixed prosthesess havehav a 6-11% requirement for endodontic treatment. This approach is moremo invasive and is irreversible.

Abstract OBJECTIVE: The aim of this paper has been to review the past and current literature on the determinants and control of soft drinks-incited dental erosion. METHODS: The authors used Medline to find relevant literature published until March 2009. Abstracts and full articles were read to identify studies and reviews describing various modifying factors and determinants of dental erosion. Additional information was obtained using manual library search. RESULTS AND CONCLUSION: Excessive exposure to various acid sources can contribute to the chemical erosion of tooth surfaces. While these acid sources have the potential to erode teeth, various chemical, biological and behavioral factors determines the erosive action of the acids they contain. Several interceptive and preventive means have been proposed to minimize damage to the dentition. Keywords: Dental erosion. Acidic drinks. Modifying factors. Treatment. Resumo OBJETIVOS: O objetivo deste artigo foi revisar a literatura passada e atual sobre os determinantes e controle da erosão dentária induzida por refrigerantes.

  • Tooth Surface Loss (TSL)
    Tooth Surface Loss (TSL) Sumamry This lesson is intended to give an overview of what to consider when treating patients with TSL, including the causes and management. Tooth surface loss can be physiological or pathological. These are distinguished by taking into account the patient’s age and the severity of tooth wear e.g. in a young person with severe TSL would be pathological, whereas in an older person with moderate TSL this may be physiological from normal use over the years. Buzz words: Erosion Abrasion Attrition Abfraction Tooth Wear Index (TWI) Basic Erosive Wear Examination (BEWE) Occlusal Vertical Dimension (OVD) Centric Occlusion (CO) Retruded contact position (RCP) Intercuspal position (ICP) Dahl Effect Diagnostic wax up Mock upsReviseDental.com Conformative Reorganised Splints (Michigan and Tanner, soft and bilaminar) Epidemiology (1) 77% of the adult population have tooth wear of some degree. (2) 15% of dentate adults exhibited moderate tooth wear (exposing substantial dentine) 2% of adults suffered from severe tooth wear (exposing secondary dentine or pulp) More prevalent in men (70%) than women (61%) Causes: There are 4 causes of tooth surface loss: 1. Erosion 2. Abrasion (Think abrasion= brushing aka an object other than an opposing tooth) 3. Attrition (Think attrition = teeth) 4. Abfraction Tooth surface loss is often a multifactorial problem. The different causes often appear simultaneously which potentiate their effects. It is important to identify the etiological factors of tooth wear so that the patient can be advised of ways to manage it.
