PURPOSE: To evaluate the effect of different degrees of mesial implant inclinations on the retention and stability of two-implant mandibular overdentures retained with stud attachments. MATERIALS AND METHODS: Four experimental mandibular acrylic models were constructed. Two laboratory implants were inserted in the canine areas of each model with the following degrees of mesial inclinations: 0, 5, 10, and 20 degrees. Experimental overdentures were connected to the implants with Locator extra-light retention (Le), Locator light retention (Ll), and Locator medium retention (Lm)...

A standardized periapical radiograph is still the most suitable technique for monitoring peri-implant osseous destruction during long-term treatment. This article describes a new method for custom fabrication of an acrylic template with standardized reproducible assessment of implants retaining mandibular bar overdentures, without removal of the bar and regardless of the implant system used.

The aim of this study is to evaluate and compare the bone stress around implants in mandibular two-implant overdentures depending on the implant location and different loading conditions. Four three-dimensional finite element models simulating a mandibular two-implant overdenture and a Locator attachment system were designed. The implants were located at the lateral incisor, canine, second premolar and crossed-implant levels. A 150 N unilateral and bilateral vertical load of different location was applied, as was 40 N when combined with midline load...

This report describes the prosthetic management of a fractured Dolder bar on a transmandibular implant system. The patient declined surgical removal of the implants. Therefore, to repair the superstructure, a cast Dolder bar was fabricated and luted onto the existing transmandibular implants. An implant-retained bar overdenture was then fabricated to rehabilitate the mandibular arch.

STATEMENT OF PROBLEM: Studies have demonstrated the effectiveness of a single-implant-retained mandibular overdenture for elderly patients with edentulism. However, due to the high concentration of stress around the housing portion of the single implant, this prosthesis tends to fracture at the anterior region more than the 2-implant-retained mandibular overdenture. PURPOSE: The purpose of this finite-element analysis study was to evaluate the stress distribution in a single-implant-retained mandibular overdenture reinforced with a cobalt-chromium framework, to minimize the incidence of denture base fracture...

REVIEW
Faraj Edher, Caroline T Nguyen
STATEMENT OF PROBLEM: Dental implants can be essential in the rehabilitation of various cancer defects, but their ideal placement can be complicated by the limited dimensions of the available host bone. Surgical interventions developed to increase the amount of bone are not all predictable or successful and can sometimes be contraindicated. Short dental implants have been suggested as an alternative option in sites where longer implants are not possible. Whether they provide a successful treatment option is unclear...

PURPOSE: Limited information is currently available relative to the effect of masticatory loads on the retentive properties of Locator attachments. The aims of this in vitro study were to assess and compare the effect of simulated mastication on the retention of white, pink, and blue Locator inserts for overdentures retained by 2 implants. MATERIALS AND METHODS: Thirty specimens simulating a nonanatomic edentulous flat ridge with two implants and an overdenture were divided into 3 groups according to the color of the fitted insert: transparent clear group (n = 10), pink group (n = 10), and blue group (n = 10)...

BACKGROUND: The longitudinal clinical outcomes over decades contribute to know potential factors leading to implant failure or complications and help in the decision of treatment alternatives. METHODS: The cases of all patients who received dental implants treated with titanium plasma-sprayed surfaces and whose prostheses were set in the period 1984-1990 at seven private practices were retrospectively analyzed. The cumulative survival rate, the cumulative incidence of peri-implantitis, and the complication-free prosthesis rate were calculated with Kaplan-Meier survival curves, and the factors' influence on implant survival rate and the incidence of peri-implantitis were determined by a single factor in univariate analyses and multivariate analyses...

INTRODUCTION: Immediate implant-loading protocol has progressed because of various clinical advantages offered by this treatment approach. However, available studies on edentulous patients are still few compared to those in which delayed implant-loading protocol was applied. AIM: This prospective study was to evaluate the implant survival rate and the peri-implant tissue response in a group of patients who received two unsplinted immediately loaded dental implants in the mandibular anterior region to retain a complete overdenture using locator attachments...

BACKGROUND: As a consensus, the 2-implant supported overdentures (ODs) are considered as the first choice of treatment for the edentulous mandible. In the same context, there is increased evidence supporting the use of single-implant OD. The aim of any design is to preserve the remaining structures and allow the longevity of the treatment. OBJECTIVES: To evaluate the impact of single implant vs 2 implants on the peri-implant marginal bone loss (MBL) and number of implant failures in mandibular implant overdentures...

PURPOSE: To assess the 5-year treatment outcome of maxillary implant-retained overdentures opposed by natural antagonistic teeth. METHODS: 50 consecutive patients received maxillary overdentures supported by six dental implants. Implants were placed in the anterior region, if enough bone was present (n=25 patients) Implant were placed in the posterior region if implant placement in in the anterior region was not possible (n=25 patients). Variables assessed included survival of implants, condition of hard and soft peri-implant tissues, and patients' satisfaction...

Implant-overdenture supported by an interforaminal bar provides stability and is effective in an edentulous atrophic mandible. However, using this attachment requires precise planning from the restorative and surgical aspects to ensure a satisfying outcome. Consdering the feature and space requirements for bar attachment, this article establishes a clinical protocol for a two-implant-retained overdenture on the mandible. In this study, a case of mandibular edentulism was considered to illustrate this protocol and provide a reference for clinical practice...

Background Funding for implant-based treatment within secondary care is limited, and acceptance criteria are determined locally according to funding agreements with NHS England. Indefinite review of all patients in secondary care is unlikely to be feasible due to limitations on departmental capacity. The increasing number of patients provided with implant-based treatment in secondary care has resulted in a growing maintenance burden, raising the question of who should provide this care. Management of some complications within primary care would facilitate patients' access to treatment, although no specific provision for maintenance of implant-retained prostheses is made within the NHS Dental Charges Regulations...
