PURPOSE Studies of maxillary overdentures supported by endosseous implants often show a high implant failure rate. The aim of the present investigation was to evaluate clinically and radiographically non-submerged implants supporting an overdenture in the maxilla. MATERIALS AND METHODS Forty-one patients were consecutively admitted for treatment. The standard procedure was to place 4 implants...

In patients with early loss of teeth and protracted denture wear, the residual bony ridge undergoes atrophic changes. This resorption is exacerbated when natural teeth are still present in the opposing arch. The excessive force from the natural dentition causes severe bone loss, producing a so-called “combination syndrome.” As a result, the removable prosthesis becomes nonretentive and unstable...

Objective: To evaluate and compare the effect of lingualized occlusion monoplane on theperi-implant bone level mandibular overdenture retained by two splinted mini-implants using Cone BeamComputed Tomography(CBCT).Methodology: Fourteen completely edentulous patients were divided randomly into equal groups: GroupI received Mini-implant retaining overdentures with their occlusal scheme set accord...

Mandibular single denture opposed by maxillary natural dentition showed a great problem. However, mandibular implant overdenture treatment has gained considerable recognition. Ten male patients with complete mandibular edentulous arch and opposing arch have full natural dentition. Patients were divided into two groups. All patients received two endosseous titanium implants. In Group I, patients...

Edentulous patients with a severely resorbed mandible often experience problems with their dentures. Treatment concepts involving two to four implants for the support of an overdenture have been proposed. The aim of this study was to develop a treatment concept for mandibular overdentures supported by endosseous implants based on a review of the literature. It is proposed that two implants supp...

STATEMENT OF PROBLEM Little has been reported about the demographics of implant placement in the Irish population and the complications that occur. This is important in terms of service planning and providing patient information. PURPOSE The purpose of this study was to construct a database of patients who had implants placed in the Dublin Dental School et Hospital from 2000 to 2006. Also, we...

Background: Reconstruction of severely resorbed jaws requires different surgical procedures to restore the correct bone morphology. These procedures often involve the use of bone substitutes or the harvesting of autologous bone from a donor site. Autologous bone is still regarded as the “gold standard” for augmentation procedures because of its osteogenic potential, but this graft has limited a...

Purpose: To evaluate success rates and complications of implants placed with a flapless technique and immediately loaded in fully edentulous maxillae. Materials and Methods: Implants were placed in fully edentulous maxillae with a minimum insertion torque of 45 Ncm in underprepared sites to allow maximum stability at insertion using a flapless technique. Implants were immediately loaded. Outcom...

In completely edentulous patients it is comparatively easy to get retention in maxillary denture due to large surface area than mandibular denture.So conventional complete dentures usually fail to satisfy the expectation of patients because of compromised retention, especiallywith mandibulardentures. This createsnegative effects on thepatient’sbehavior towards prosthodontics treatment. So a reh...
