objectives: this study aimed to compare the diagnostic accuracy of inverted and unprocessed digitized periapical radiographs for detection of peri-implant defects. materials and methods: a total of 30 osteotomy sites were prepared in three groups of control, study group 1 with 0.425 mm defects and study group 2 with 0.725 mm defects using the sic and astra tech drill systems with 4.25mm and 4.8...

background: fracture load of implant-supported restorations is an important factor in clinical success. this study evaluated the effect of two techniques for screw access hole preparation on the fracture load of cement-screw retained implant-supported zirconia-based crowns. methods: thirty similar cement-screw retained implant-supported zirconia-based maxillary central incisor crowns were evalu...

OBJECTIVE This study determined the effect of metallic radial head arthroplasty on radiocapitellar joint contact area. DESIGN The contact area of eight intact radiocapitellar joints was assessed during simulated compressive loading. Subsequently, the same experiments were repeated after reconstruction with three different radial head implant sizes. BACKGROUND There has been an increasing us...

OBJECTIVES To determine the reliability of reformatted 2D-CT for pre-operative planning of implant placement. METHODS One hundred consecutive partially or fully edentate patients underwent 2-D reformatted CT pre-operative planning and subsequent implant placement. The number, site and size of the implants, the available bone height and anatomical complications were recorded. The pre-operative...

Abstract Introduction Peri-implant fluid more than 6 months from surgery is a known complication of breast surgery.Differential diagnosis includes infection, inflammation,implant rupture and haematoma.Other infection raised no concern until the identification Breast Implant Associated Anaplastic Large Cell Lymphoma(BIA-ALCL). Method Retrospective electronic data collection for women 18 years or...

OBJECTIVES To assess the satisfaction of men with their testicular implants after undergoing orchidectomy for testicular cancer, and to determine their reasons for accepting or declining a prosthesis. PATIENTS AND METHODS In all, 424 men who had undergone radical orchidectomy and were part of the testicular cancer follow-up programme were sent an anonymous questionnaire comprising 10 question...

Implant malposition without capsular contracture is a common problem that has received little attention. Malposition of the implant in the inferior, lateral, or medial direction can be corrected predictably and relatively simply with capsulorrhaphy and mirror-image selective capsulotomy. In addition, capsulorrhaphy can be used to create a smaller pocket to preserve anterior projection and preve...

The purpose of this study is to compare the stress of the bone around the mini-implant under the two kinds of force: the composite force which contains torque and traditional single force. There were 96 finite element models formed by the combination of mini-implant and bone, with diameters of 1.2 mm, 1.6 mm, 2.0 mm and corresponding length being 6 mm, 8 mm, 10 mm, 12 mm, respectively. Each siz...

This study's objective was to identify, in a statistically valid and efficient manner, the risk factors associated with dental implant failure. We hypothesize that factors exist which can be modified by clinicians to enhance outcome. A retrospective cohort study design was used. Cohort members had >or= one implant placed. Risk factors were classified as demographic, health status, implant-, ana...
