800x600 in order to determine the effect of intracorneal rings (intacs sk), when implanted in keratoconic patients, on corneal curvature, uncorrected visual acuity (ucva), best corrected visual acuity (bcva) and on the progression of the cone through three years follow-up period. in this prospective nonrandomized study 114 eyes of 71 keratoconic patients (38 females and 33 males) were implanted...

Augmentation of deficient and atrophic alveolar ridges is an important aspect of dental implant therapy with the goal of providing a functional restoration in harmony with adjacent natural dentition. Bone splitting technique is considered a distinguished augmentation method for treatment of deficient alveolar ridges. According to this procedure, the compromised alveolar ridge is opened from the...

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...

The increasing variety of breast implants has led to their classification into "profile" types to guide implant cataloguing and selection. Implant "profile" describes the overall silhouette of the implant. It represents a permutation of all 3 dimensions of the implant: base diameter, projection, and volume. Implant "profile" is not the same as implant projection. Implant projection is a quantif...

background and objectives: one of the simplest and cheapest attachments for overdentures, is the ball-type attachment, however, keeping it during the first year of prosthesis delivery and after that is one of the main concerns of dentists. the present study aimed to assess the wear of matrix in overdentures attachment supported by one, two and three implants in the mandible. materials and metho...

in recent years, more attention is paid to stainless steel 316l as fracture plate and fixation in human's body. present studies are focused on surface and metallurgical properties of this material. biocompatibelity of this material and its superior mechanical properties has made it the most demanded biomaterial. in this research, four different implants are investigated in three stages. four co...

conventional implant dentistry has been limited to healed edentulous ridges with adequate bone. predictable success rates resulted in using dental implants in compromised situations such as insertion into old infected sites or near to pathological areas. there is significant data about marginal bone loss and lack of osseointegration around the neck of implants. however, the data about peri apic...

Implant design refers to the three-dimensional structure of the implant, with all the elements and characteristics that compose it. Dental implants are subjected to various force magnitudes and directions during function. Because implants function to transfer occlusal loads to the surrounding biologic tissues, functional design objectives should aim to manage biomechanical loads to optimize the...

Nowadays total joint replacements are widely used in the world, so in average 800,000 joint surgeries are done yearly only in Europe and North America. However implant loosening is and remains as the major issue of all implant failures and therefore causes revision surgery procedures. Studies and experiments have identified poor fixation of implants most likely is the main cause of long term im...
