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...

Abstract The initial stability after implantology is paramount to the survival of dental implant, and surface roughness implant plays a vital role in this regard. characterisation topography complicated branch metrology, with huge range parameters available. Each parameter contributes significantly towards mechanical properties three-dimensional printed specimens. purpose paper experimentally i...

It has become generally accepted that the cement surrounding a proximal femoral implant should be not less than 2 mm thick and that it should be complete i.e. without any ‘windows’ in the mantle. The widely used Barrack grading for cementing included no comment on the thickness of the cement mantle on its introduction in 1992 [1]. The following year the ‘A’ grade was qualified by the addition o...

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...

STATEMENT OF PROBLEM The external contour of an implant and the magnitude of occlusal loading can have significant effects on the load transfer characteristics and may result in different bone failure rates for different implant systems. PURPOSE The goal of this study was to investigate the effects of external geometry and occlusal load magnitude on bone failure modes for 5 commercially avail...

Among 2528 patients operated on using pins, rods, bolts, and screws made of polyglycolic acid or polylactic acid, 108 (4.3%) were affected by a clinically significant local inflammatory, sterile tissue reaction. The three most common indications for the use of these fixation devices were a displaced malleolar fracture, a chevron osteotomy for hallux valgus, and a displaced fracture of the radia...
