Complete edentulism often limits patients' ability to masticate and perform other oral functions, resulting in a reduction of oral-health-related quality of life. Although the two-implant mandibular overdenture may be considered as a minimum standard of treatment of complete edentulism, patients often prefer conventional complete dentures due to cost and surgical procedures related to implant supported dentures. Many complete denture patients may have limited access to dental care due to socioeconomic or health issues, hence there is a need in simplification of complete denture fabrication...

This study evaluated the effect of implant diameter on strain around implants retaining mandibular overdentures with Locator attachments. Three mandibular acrylic resin models were constructed with 2 implants inserted in canine areas and classified according to implant diameter into 3 groups: large (4.2 mm), medium (3.7 mm), and small (3.3 mm) diameter implants. Duplicate dentures were connected to the implants with Locator attachments. Four strain gauges were bonded to the acrylic resin at mesial, distal, buccal and lingual surfaces of each implant and strain was measured at loading and non-loading sides during 1st premolar and 1st molar loading...

PURPOSE: Maxillary implant overdentures are often designed without palatal coverage to maximize wearer comfort. Although palateless dentures have been reported to be less rigid than conventional dentures, and require reinforcement to prevent complications, there is little documentation about the effects of such reinforcement. The purpose of this study was to examine the effects of reinforcement on the strain on maxillary implant overdentures supported by implants in a variety of configurations...

A review in affected person's attitude in abstract care of edentulous patients has to be a priority in elderly individuals. The development of complete dentures (CDs) has been the selection of remedy retaining in mind the socioeconomic popularity, age, and nutritional elements. However, most of the patients complain of loss of retention in mandibular implant-supported overdentures (ODs), which compensated the downside of the loss of retention in complete dentures (CDs). Moreover, implant supported over dentures (ISOVDs) supplied accurate exceptional of lifestyles, esthetics, progressed nutritional deficiencies, and provided good patient satisfaction...

BACKGROUND: Dental implant-retained overdentures have been chosen as the treatment of choice for complete mandibular removable dentures. Dental implants, such as mini dental implants, and components for retaining overdentures, are commercially available. However, comparative clinical studies comparing mini dental implants and conventional dental implants using different attachment for implant-retained overdentures have not been well documented. PURPOSE: To compare the clinical outcomes of using two mini dental implants with Equator(®) attachments, four mini dental implants with Equator attachments, or two conventional dental implants with ball attachments, by means of a randomized clinical trial...

Extracellular DNA (eDNA) has been identified in the matrix of many different monospecies biofilms in vitro, including some of those produced by oral bacteria. In many cases, eDNA stabilizes the structure of monospecies biofilms. Here, the authors aimed to determine whether eDNA is an important component of natural, mixed-species oral biofilms, such as plaque on natural teeth or dental implants. To visualize eDNA in oral biofilms, approaches for fluorescently stained eDNA with either anti-DNA antibodies or an ultrasensitive cell-impermeant dye, YOYO-1, were first developed using Enterococcus faecalis, an organism that has previously been shown to produce extensive eDNA structures within biofilms...

Dental implants play an important role in postoperative rehabilitation after surgical treatment of oral cancer through the provision of prosthetic tooth replacement. Two major implant prosthesis designs are available: fixed implant-supported prostheses and implant-supported overdentures. We herein report a case of a 16-year-old female patient who underwent alveolar ridge resection for treatment of mandibular gingival carcinoma. Following surgery, oral rehabilitation was attempted using an implant-supported overdenture on a gold bar retainer splinting four implants...

BACKGROUND: There are many implant cases in which dental technicians take initiative with regard to the design of implant prostheses, and to a certain extent, this area of care is one in which dentists do not necessarily play the leading role. Moreover, inadequate communication between dental technicians and dentists and insufficient instructions for technicians has been highlighted as issues in the past. The purpose of this questionnaire is to improve the quality of implant prostheses and thereby contribute to patient service by clarifying, among other aspects of treatment, problem areas and considerations in the fabrication of implant prostheses, conceptual-level knowledge, and awareness of prosthodontics on the part of the dentists in charge of treatment and methods for preventing prosthetic complications...
