    CAD/CAM Veneers and Crowns

     

    21. Case of the month Restoration of Anterior Ridge Deficiency with Block Allograft and Dental Implants: A Visual Case Report By Sammy S. Noumbissi

    The aim of this case report is to demonstrate an alternative technique for restoration of an anterior ridge deficiency to facilitate placement of dental implants. Traditionally, deficiencies of this magnitude have been restored with autografts such as ramus blocks, symphysis blocks, iliac crest bone, or tibial bone. These traditional regenerative techniques have the drawback of a secondary surgical site that creates additional patient morbidity. Utilization of block allografts, as described in this case report improves patient post-surgical recovery by elimination of the secondary surgical site for autograft harvest. The block and particulate allograft used in this case report healed uneventfully and allowed for placement of multiple dental implants which have been successfully restored and in function for more than 2 years.

    29. CAD/CAM Dentistry – Computerized Anterior Restorations Part 1: CAD/CAM Veneers and Crowns By Dean C. Vafiadis

    Recently, an influx of computer technologies and CAD/CAM designs have been introduced to the restorative dentist. These technologies have helped streamline our fabrication protocols, reduced clinical chair-time and reduced laboratory costs. In addition, the accuracy of these techniques have equaled our conventional techniques with high level of precision. Using a combination CAD/CAM and robotics, the technology of final implant abutment fabrication and final CAD/CAM restoration is predictable for the clinician. The aim of this article is to demonstrate cases in which CAD/CAM technology was utilized for esthetic anterior restorations.

    39. The Use of a Novel Nano-Crystalline Calcium Sulfate for Bone Regeneration in Extraction Socket By Ziv Mazor, Robert Horowitz, John Ricci, Harold Alexander, Ioana Chesnoiu-Matei. Sachin Mamidwar

    Adequate vital bone volume (BV) is essential for successful dental implant placement with satisfactory esthetic results. Calcium sulfate (CS) has osseoconductive, angiogenic, biocompatible and barrier properties. As CS dissolves it leads to formation of biological apatite and causes a local release of growth factors. NanoGen (nCS) is a granular material comprised of tightly compressed nanocrystalline CS that undergoes controlled degradation. This case report uses nCS for the regeneration of bone in an extraction socket.

    51. The Influence of Smoking on Moderately Rough-Surfaced Dental Implants: A Literature Review By Osama Noorwali, Hassan Ali Alremthi, Douglas Deporter

    Smoking cigarettes has been shown to be detrimental for dental implant health as it is for periodontal health. Most studies published to date relate to the risk of smoking in patients with machine-turned dental implant designs like the original Branemarktype implant. However, increasing implant surface roughness can have a profound effect on osteoconduction and early bone healing around implants, and this has been suggested to provide a benefit for smokers wishing to have implants. The aim of the present paper was to assess published information on any relationship between smoking cigarettes and rough-surfaced implant performance. An English literature search was done using PubMed & Ovid Medline to identify relevant papers published between 2000 and 2010. No consensus could be found possibly due to differing study designs and confounding factors such as a history of periodontal disease. Prospective, split-mouth studies comparing machineturned and moderately rough implant designs in smokers vs non-smokers are sadly lacking.
