Retrospective Clinical Study of 656 Cast Gold Inlays/Onlays in Posterior Teeth, in a 5 to 44-Year Period: Analysis of Results
Retrospective clinical study of 656 cast gold inlays/onlays in posterior teeth, in a 5 to 44-year period: Analysis of results Ernesto Borgia, DDS1, Rosario Barón, DDS2, José Luis Borgia, DDS3 DOI: 10.22592/ode2018n31a6 Abstract Objective. 1) To assess the clinical performance of 656 cast gold inlay/onlays in a 44-year period; 2) To analyze their indications and distribution regarding the evolution of scientific evidence. Materials and Methods. A total of 656 cast gold inlays/onlays had been placed in 100 patients. Out of 2552 registered patients, 210 fulfilled the inclusion criteria. The statistical representative sample was 136 patients; 140 were randomly selected and 138 were the patients studied. Twelve variables were analyzed. Data processing was done using Epidat 3.1 and SPPS software 13.0. Results. At the clinical examination, 536 (81.7%) were still in function and 120 (18.3%) had failed. According to Kaplan-Meier’s method, the estimated mean survival for the whole sample was 77.4% at 39 years and 10 months. Conclusions. Knowledge updating is an ethical responsibility of professionals, which will allow them to introduce conceptual and clinical changes that consider new scientific evidence. Keywords: inlays/onlays, molar, premolar, dental bonding restorations, scientific evidence-based, minimally invasive dentistry.

Changing Vertical Dimension: a Solution Or Problem? by Peter E
Continuing Education Changing Vertical Dimension: A Solution or Problem? by Peter E. Dawson, DDS Abstract Much of what dentists know about the vertical dimension of occlusion (VDO) has changed from the dogma of a few years ago. Dentists who understand the fundamental concepts of VDO can use those concepts to great advantage in treatment planning. Failure to understand can (and often does) lead to missed diagnoses, failed treatment outcomes, and serious examples of unnecessary overtreatment. This article explains some of the principles that make changes in VDO advantageous and predictable, and exposes some of the misconceptions that are problematical. Learning Objectives After reading this article, the reader should be able to: recognize the importance of vertical dimension as it applies to treatment planning for anterior teeth. discuss why posterior segmental bite-raising appliances are contraindicated. describe how changes in vertical dimension affect buccolingual relationships of posterior teeth. explain why the effect of changing vertical dimension is best studied on face-bow mounted diagnostic casts. The Concept of Balance The equilibrium of the entire masticatory system is dependent on balance.1 The mandible at rest is balanced between the resting lengths of the elevator muscles and the depressor muscles (Figure 1 View Figure). Anything that affects the resting length of either group of opposing muscles can affect the critical relationship of the mandible with the maxilla at the resting position. Because the teeth are not in contact at the rest position and the mandible-to-maxilla relationship is not consistent,2,3 the rest position is not an accurate determinant of the jaw-to-jaw relationship at maximum intercuspation. -
Opening Vertical Dimension: How Do You Do It? by Evelyn Shine, DDS
Opening vertical dimension: how do you do it? By Evelyn Shine, DDS Introduction Vertical dimension of occlusion is used to denote the superior inferior relationship between the maxilla and the mandible when teeth are in maximum intercuspation. When vertical dimension is decreased significantly, either via loss of teeth or parafunction, the result can be a collapsed bite. RELATED READING | Harmony in prosthodontics As vertical dimension is lost, the proportions of the face are altered; one’s chin becomes recessed, the lower half of the face may look short, and the angles of the mouth can develop chelitis. Loss of vertical dimension results in facial collapse, wrinkles by the nasolabial fold, and appearance of compressed and thin lips, which makes one appear older. RELATED READING | All-On-4 treatment option: a case report Dentures can be fabricated to correct a collapsed bite and increase vertical dimension in patients with missing teeth. Alternatively, vertical dimension can also be increased via an acrylic bite plate and/or fixed prosthodontic work. Case report A 60-year-old male patient presents to the dental office with the following chief complaint: “My lower teeth are getting shorter.” Upon visual extraoral examination, the patient had difficulty keeping his lower jaw still at all times; upon sitting still, the patient’s jaw tremors from side to side. It appears as though the patient may have Parkinson’s disease; however, the patient states that his medical conditions only include diabetes and hypertension. He is taking lisinopril to control his blood pressure. He denied tremors or Parkinson’s. Initial dental exam Fig. -

Chapter 2 Implants and Oral Anatomy
Chapter 2 Implants and oral anatomy Associate Professor of Maxillofacial Anatomy Section, Graduate School of Medical and Dental Sciences, Tokyo Medical and Dental University Tatsuo Terashima In recent years, the development of new materials and improvements in the operative methods used for implants have led to remarkable progress in the field of dental surgery. These methods have been applied widely in clinical practice. The development of computerized medical imaging technologies such as X-ray computed tomography have allowed detailed 3D-analysis of medical conditions, resulting in a dramatic improvement in the success rates of operative intervention. For treatment with a dental implant to be successful, it is however critical to have full knowledge and understanding of the fundamental anatomical structures of the oral and maxillofacial regions. In addition, it is necessary to understand variations in the topographic and anatomical structures among individuals, with age, and with pathological conditions. This chapter will discuss the basic structure of the oral cavity in relation to implant treatment. I. Osteology of the oral area The oral cavity is composed of the maxilla that is in contact with the cranial bone, palatine bone, the mobile mandible, and the hyoid bone. The maxilla and the palatine bones articulate with the cranial bone. The mandible articulates with the temporal bone through the temporomandibular joint (TMJ). The hyoid bone is suspended from the cranium and the mandible by the suprahyoid and infrahyoid muscles. The formation of the basis of the oral cavity by these bones and the associated muscles makes it possible for the oral cavity to perform its various functions. -

Computed Tomography of the Buccomasseteric Region: 1
605 Computed Tomography of the Buccomasseteric Region: 1. Anatomy Ira F. Braun 1 The differential diagnosis to consider in a patient presenting with a buccomasseteric James C. Hoffman, Jr. 1 region mass is rather lengthy. Precise preoperative localization of the mass and a determination of its extent and, it is hoped, histology will provide a most useful guide to the head and neck surgeon operating in this anatomically complex region. Part 1 of this article describes the computed tomographic anatomy of this region, while part 2 discusses pathologic changes. The clinical value of computed tomography as an imaging method for this region is emphasized. The differential diagnosis to consider in a patient with a mass in the buccomas seteric region, which may either be developmental, inflammatory, or neoplastic, comprises a rather lengthy list. The anatomic complexity of this region, defined arbitrarily by the soft tissue and bony structures including and surrounding the masseter muscle, excluding the parotid gland, makes the accurate anatomic diagnosis of masses in this region imperative if severe functional and cosmetic defects or even death are to be avoided during treatment. An initial crucial clinical pathoanatomic distinction is to classify the mass as extra- or intraparotid. Batsakis [1] recommends that every mass localized to the cheek region be considered a parotid tumor until proven otherwise. Precise clinical localization, however, is often exceedingly difficult. Obviously, further diagnosis and subsequent therapy is greatly facilitated once this differentiation is made. Computed tomography (CT), with its superior spatial and contrast resolution, has been shown to be an effective imaging method for the evaluation of disorders of the head and neck.
