context a key determinant for clinical success is the diagnosis of the bone density in a potential implant site. the percentage of bone-implant contact is related to bone density, and the axial stress contours around an implant are affected by the density of bone. evidence acquisition a number of reports have emphasized the importance of the quality of bone on the survival of dental implants. t...

Background: In the past few years, the occurrence of an oral lesion, called osteonecrosis of the jaw (ONJ), has been increasingly reported in patients undergoing treatment with bisphosphonates (BPs); however, few published histological studies of ONJ can be found in the literature. Purpose: The aim of the present case was to report an occurrence of ONJ after implant insertion. Materials and Met...

Peri-implantitis has been defined as an inflamematory condition involving dental implants, surrounding mucosa and bone, which lose supporting bone. Although high success rates for endosseous implants have been reported, failures occur, and some implants are lost or removed. At least 10% of the failures have been suggested to be the result of peri-implantitis. One of the major causes of the peri...

In this paper biomechanical interaction between osseointegrated dental implants and bone is numerically investigated through 3D linearly elastic finite-element analyses, when static functional loads occur. Influence of some mechanical and geometrical parameters on bone stress distribution is highlighted and risk indicators relevant to critical overloading of bone are introduced. Insertions both...

background and aims. because of compromised angulations of implants, the abutments are sometimes prepared. the purpose of this study was to investigate the effect of removing one wall of the implant abutment on the retention of cement-retained crowns. materials and methods. four prefabricated abutments were attached to analogues and embedded in acrylic resin blocks. the first abutment was left ...

Aim. Endosseous implants are widely used to replace missing teeth but mucositis and peri-implantitis are the most frequent long-term complications related with dental implants. Removing all bacterial deposits on contaminated implant surface is very difficult due to implant surface morphology. The aim of this study was to evaluate the bactericidal potential of photodynamic therapy by using a new...

PURPOSE Contact and distance osteogenesis occur around all endosseous dental implants. However, the mechanisms underlying these processes have not been fully elucidated. We hypothesized that these processes occur independently of each other. To test this, we used titanium (Ti) tubes to physically separate contact and distance osteogenesis, thus allowing contact osteogenesis to be measured in th...

Subperiosteal implants used to be prescribed to partially and fully edentulous patients to restore occlusion and esthetics prior to the emergence of the more successful endosseous implants that are used today. Because subperiosteal implants had a high incidence of failure, difficulty of placement, and post-operative complications, the use of subperiosteal implants declined significantly. Howeve...

A new computer software program that generates panoramic and oblique computed tomography scans was used to examine 205 patients who were being considered for endosseous dental implants in the mandibular or maxillary arches. This technique allowed recognition of the course of the inferior alveolar nerve canal and measurement of the alveolar ridge, which facilitated the design and placement of an...

With regards to their biological and physiochemical properties, titanium-based biomaterials have been successfully used in orthopaedic, dental and maxillo-facial surgery mainly as endosseous implants. The early osseointegration of titanium dental implants is an important factor for their clinical success. The implant loading to bone is influenced by various factors, including surface chemistry,...
