Titanium implants commonly used in orthopedics and dentistry integrate into host bone by a complex and coordinated process. Despite increasingly well illustrated molecular healing processes, mechanical modulation of implant bone ingrowth is poorly understood. The objective of the present study was to determine whether micromechanical forces applied axially to titanium implants modulate bone ing...

PURPOSE The aim of the present prospective cohort study was to report on an approach for maxillary reconstruction with autogenous bone grafts allowing implant placement for immediate function with fixed bridges after 6 months. MATERIALS AND METHODS A total of 35 bilateral bone grafting procedures were performed on 35 consecutive patients (mean age 54.5 years). The iliac crest was used as dono...

Early osseointegration of cementless implants is fundamental for the longevity of the implant. The discovery of the RGD peptide, as an important mediator of osteoblast adhesion to implants, has lead to a new approach in designing biomaterials for use in orthopedic surgery. Implants can be biologically modified by covalent immobilization of RGD peptide on the surface of the implant. Immobilized ...

Abstract Background Implants immediately loaded full-arch prosthesis in maxilla is always a challenge, especially when the zone 2 extremely defected. To achieve satisfying result, different therapeutic alternatives have been proposed, such as zygomatic implant, pterygoid implant; however, precise surgical skills limited its application. Case presentation This study reported case that an edentul...

Introduction Titanium and its alloys have excellent mechanical properties and biocompatibility. In the field of dentistry, smooth surfaced titanium implants inserted into the facial bones perform very well. After implantation, well-fixed dental implants, which are not subjected to weight loading during some period after implantation, exhibit direct contact with bone without intervening fibrous ...

AIM Evaluation of some morphological oral aspects perceived as decision factors in complete edentulism treatment by mini-implants overdenture. PATIENTS, MATERIAL AND METHODS An observational study was conducted on a sample of 24 patients (average age of 61 years), through clinical and imagistic methods. The variables taken into consideration were: age, gender, alveolar mucosa status, bone off...

PURPOSE A zygomatic implant can be an effective device for rehabilitation of the severely resorbed maxilla. If zygomatic implants are used, onlay bone grafting or sinus augmentation would likely not be necessary. Where an anterior onlay bone graft is required, extension of the graft in the posterior region could be reduced. The results of the application of zygomatic implants in 9 patients and ...

PURPOSE The purpose of this study was to evaluate the soft tissue and bone change around two adjacent implants in one-stage implant surgery. METHODS Eleven subjects (7 males, 4 females) who were needed placement of 2 adjacent implants in the molar area were included. The two implants were placed with the platform at the level of the alveolar crest. The interproximal bone between the 2 implant...

OBJECTIVE To determine the pattern of stability changes as a reflection of early healing around single-stage roughened-surface implants in humans utilizing resonance frequency analysis (RFA). MATERIALS AND METHODS Hundred twenty-five patients who demanded dental implants were treated with two different implant (Nobel Biocare Replace™ and Strumman™ ITI) systems. Bone type was classified into f...

The objectives of this study are to present a new concept of the bone anchorage using long implants in remote bone sites and to discuss four cases treated with this method. Our patients were treated with long implants with a distant anchorage in the skull bone. The planning procedure, the construction of the drill guide, and the surgical protocol are described. In the clinical cases described, ...
