Introduction: The survival of an implant system is affected by the choice of antirotational design, which can include an external or internal hex. Implant success also is affected by the maintenance of the crestal bone around implants. The aim of present study was to evaluate the crestal bone loss and clinical parameters related to bone loss in patients loaded with an external or internal hex 3...

This work presents a numerical approach in order to predict the influence of implant material stiffness in a femoral component design when submitted in compression. The implant success depends on the transferred load to the neighboring bone. The finite element method can be used to analysis the stress and strain distribution in the femoral component allowing to improve the implant selection. Fo...

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...

peri-implantitis is a site-specifi c infectious disease that causes an infl ammatory process in soft tissues, and bone loss around an osseointegrated implant in function. the etiology of the implant infection is conditioned by the status of the tissue surrounding the implant, implant design, degree of roughness, external morphology, and excessive mechanical load. the microorganisms most commonl...

objectives: implant primary stability is one of the important factors in achieving implant success. the osteotome technique may improve primary stability in patients with poor bone quality. the aim of this study was to compare implant stability using two different techniques namely osteotome versus conventional drilling in the posterior maxilla. materials and methods: in this controlled randomi...

Abstract This clinical report presents a case of abutment fracture, due to occlusal overload, occurred with an implant-supported restoration on right mandibular first molar of a female patient. After 6 months of prosthetic reconstruction implants, the patient returned to the clinic due to the loss of implant crown. The fractured fragment of the abutment with the screw protec...

providing an esthetic restoration in the anterior region of the mouth has been the basis of peri-implant esthetics. to achieve optimal esthetics, in implant supported restorations, various patient and tooth related factors have to be taken into consideration. peri-implant plastic surgery has been adopted to improve the soft tissue and hard tissue profi les, during and after implant placement. t...
