Complications of Removable Implant Supported Prostheses

Introduction The two main complications that result from removable implants are biological and mechanical/technical complications. There is need to assess and interpret data on the incidence of complications, both biological and technical with caution. Berglundh, Persson, and Klinge (2002), found that implant loss was the most common problem, while technical complications were observable in about 60-80% and biological complications – 40-60% of the studies they evaluated. According to Sadowsky (2007), there are no specifications on the length, distribution, and number of implants; however the suggestion for non-palatal coverage designs should be a minimum of 4 implants. In case of risk ...

With four treatment options, the patient must undergo a thorough consultation with the clinician, covering each restoration type. Each treatment presentation will include the benefits and drawbacks the that particular method, risks and/or impediments associated with placement, complications that can arise after placement and daily maintenance protocols. The presentations must be clear and concise and devoid of scientific terminology that may not be recognized by the patient. To enhance understanding, it is recommended that the presentations utilize models, photographs and/or drawings representing the final product; images of previous cases can be used if they comply with all patient confidentiality ...

GENERAL INFORMATION ON DENTAL IMPLANT TREATMENT

Objective of dental implants After losing teeth, the supporting bone segment is no longer essential and begins to gradually disappear (Misch, 2008). Once this begins, the missing portions can be replaced with removable dentures or fixed bridges; this process enhances visual appeal, corrects speech impediments and improves mastication. However, complications can occur when replacing living tissues with artificial apparatuses. Dentures have been shown to decrease the efficiency of the chewing process, initiate additional bone loss and often experience inadequate retention (Knowles, 1958). Furthermore, dentures may require additional support, which affects the healthy teeth that are ...

Introduction

Dental implants are increasingly becoming popular because a large section of clinicians believe that natural tooth restoration techniques are inferior to dental implants as implants have a longer life than natural tooth and are less susceptible to biological changes. There are various types of dental implants that support crown, bridges, and dentures, and act as orthodontic anchors and facial prosthesis. The basis of the modern dental implant is a biological process in which titanium forms a bond with bone. Dental fixture is first implanted and then a prosthetic is added. Over the years, various implant impression techniques, such as ...

Among the outstanding architectural masterpieces of the XX century the Guggenheim Museum at Bilbao definitely stands out. This is not only because of its blatant deconstruction, but also the value it is to the city, as a museum and an architectural piece. Frank Gehry made his masterpiece as contemporary as possible. To such extent that even critics lament about his novel style and vision of architecture. In Spain, hardly anyone can be surprised by whimsical architectural forms, bearing in mind the works of Antonio Gaudi in Barcelona. However, Frank Gehry seems to have outwitted the latter. What he created, ...

NITROGEN AND COPPER DOPED SOLAR LIGHT ACTIVE TIO2 PHOTOCATALYSTS FOR WATER DECONTAMINATION

Abstract: A new category of photocatalytic coating that can degrade chemical as well as bacterial contaminants under visible sunlight wavelengths was generated by the deposition of a stable photocatalytic TiO2 film over the internal lumen of glass bottles by means of a sol–gel technique. Such a coating was produced either in doped or undoped form. This coating used copper and/ or nitrogen for producing visible light-active TiO2 films that were normalized or annealed at 600 ◦C and were characterized by Raman and X-ray photoelectron spectroscopy. The degradation of methylene blue was seen to accelerate with doped and undoped TiO2 films ...

Activity-based costing focuses on the activities on specific items and not the products of a given firm. In addition, activity-based costing effectively identifies specific activities within a firm whilst assigning the associated costs on the basis of the levels of consumption. Notably, activity-based costing is different from conventional costing on the basis that the former categorizes overheads as direct costs. Theoretically, Competition Bikers merger should not adopt activity based costing as a replacement of the conventional accounting system but as a complimentary or additional accounting system. This will help to transform the company’s accounting process into an authentic state. There may ...
