PURPOSE: Occlusal overload may cause implant biomechanical failures, marginal bone loss, or even complete loss of osseointegration. Thus, it is important for clinicians to understand the role of occlusion in implant long-term stability. This systematic review updates the understanding of occlusion on dental implants, the impact on the surrounding peri-implant tissues, and the effects of occlusal overload on implants. Additionally, recommendations of occlusal scheme for implant prostheses and designs were formulated...

An implant-supported fixed dental prosthesis is one of the treatment options for an individual with a completely edentulous maxilla. However, a screw-retained or cemented prosthesis can make oral hygiene difficult, especially for patients with a history of periodontal disease or disabilities. Compared with maxillary fixed dental prostheses, implant-supported overdentures offer similar retention and function and facilitate esthetics, phonetics, and hygiene. This report describes the prosthetic rehabilitation of a patient with an edentulous maxilla and a severe maxillomandibular discrepancy that involved the use of a novel prefabricated telescopic system to retain an implant-supported removable dental prosthesis...

OBJECTIVES: The aim of this study was to investigate the outcomes of the installation of two implant-supported overdentures until such treatment is complete. Although this treatment is well established in the literature, there are no studies comparing what happens to muscles and the quality of life (QoL) of patients during the treatment. METHODS: We selected 13 completely edentulous patients, according to inclusion and exclusion criteria, to rehabilitate with mandibular overdentures retained by two dental implants and a complete denture as antagonists...

OBJECTIVES: The goal of this meta-analysis was to evaluate how muscular activity, measured by electromyography (EMG), differs among edentulous patients treated with a complete denture (CD), removable implant overdentures (IO), implant-retained fixed dental prostheses (IFDP), and dentates. The differences during clenching and chewing were of particular interest. MATERIALS AND METHODS: An electronic literature review was carried out on MEDLINE (Pubmed) and the Cochrane Library covering the period January 1980 through September 2013...

OBJECTIVE: No controlled clinical study has evaluated Oral Health Related Quality of Life (OHRQOL) of immediately placed and loaded implants retaining mandibular overdentures. This pilot study evaluated the impact of immediate loading of delayed versus immediately placed dental implants on overdenture patients' OHRQOL. MATERIALS AND METHODS: Two patient treatment groups received a maxillary conventional complete denture, opposing a mandibular overdenture immediately loaded on implants with ball attachments; In group one a delayed implant placement surgical protocol was followed, whereas in group two, patients had mandibular teeth extracted and two implants immediately placed...

The oral handicap of complete edentulism is the terminal outcome of a multifactorial process involving biological factors and patient-related factors. Fully edentulous orally handicapped older adults have been neglected because removable acrylic dentures have been the classic therapy for complete edentulism but are only rehabilitative, not therapeutic. Not replacing missing teeth with stable dentures could prevent adequate food intake. Osseointegrated endosseous implants used as a therapeutic adjunct can reduce the problem of long-term bone resorption to less than 0...

With the increasing average life expectancy of human beings, the need to cater geriatric patients is ever increasing. Complete dentures are an indispensable tool in this regard. The loose and unstable lower complete denture owing to residual ridge resorption is one of the most common problems faced by edentulous patients. Dental implant retained overdentures have emerged as an efficient treatment modality for such patients. Though useful, not every patient is a suitable candidate to go for conventional implant-borne prosthesis, limitation being the available bone width...

INTRODUCTION: In the era of implant supported restorations, conventional complete denture (CD) for isolated edentulous maxilla still remains the first choice of treatment despite being its frequent mechanical failures. STATEMENT OF PROBLEM: Edentulous maxillary arch restored with polymethyl methacrylate (PMMA) based CDs when opposed by natural and/or restored dentition is biomechanically and functionally a compromised rehabilitation. MATERIALS AND METHODS: Seven patients (4 males, 3 females) in the age range of 55-75 years were treated for their frequent fracture of the single maxillary denture...

The need for treatment in cases of missing teeth may result from aesthetic demands or functional impairment, although tooth loss itself does not necessarily constitute a need for prosthetic replacement. In selected cases, restorative treatment can be replaced by tooth autotransplantation or substitution orthodontic treatment. The authors have tried to make an index based not on missing particular teeth, but on the presence of spacing requiring restoration. An attempt has been made to categorize the restorative treatment need...

Fabrication of dentures aided with implants has become a preferred treatment option for rehabilitation of completely and partially edentulous patients when durability is concerned. Simulation to natural teeth in terms of esthetics and to a greater extent in function can be considered as key elements in the raise of implant dentistry worldwide. Despite its high success rate, therapy with osseointegrated dental implants is not free of complications. Implant failure can occur for other reasons, with implant fracture being one of the major reasons for late failure...

Fabrication of implant-supported maxillary or mandibular overdentures can seem to be difficult procedures. Many things could go wrong and/or unnoticed until the fabrication has been completed. Implants must be correctly surgically placed in viable bone at the proper angulation and spacing within an arch. The type of attachment must be considered and future treatment of the appliance should be simple and efficient. The appliance must function not only initially but also for many years to come. The author has found the use of the GPS attachment to be an ideal tool to achieve the goals of retention and stability...

Ceria-stabilized zirconia/alumina nanocomposite (Ce-TZP/A) exhibits an elasticity equivalent to that of cobalt-chromium alloy and a flexural property that is superior to that of yttria-tetragonal zirconia polycrystal. Therefore, the use of Ce-TZP/A for the fabrication of removable dental prosthesis frameworks is being studied. However, the current English literature does not include any clinical report on the use of Ce-TZP/A for the fabrication of the entire framework. This clinical report describes the process and outcomes of fabricating a mandibular implant-supported overdenture and a maxillary complete denture with Ce-TZP/A as the framework material...
