Clinicians very often have seen marginal bone loss around dental implants at the crest level early on after implant placement and uncovering. Early clinical publications had suggested that this bone loss occurred during the first year of loading. Thus, numerous attempts have been made to minimize or eliminate such bone loss. However, the timing and reason for this bone loss are not always apparent. The objective of this study was to review the evidence regarding marginal bone loss around dental implants from the standpoint of biologic consequences to help understand marginal bone changes around dental implants...

Zirconia exhibits good tissue compatibility and nontoxicity, making it a widely used esthetic replacement material for implant abutments. To avoid abutment-fracture, the parts composed of zirconia with a bonded metal component connected to the implant can be used. The purpose of this study was to design titanium and zirconia components with high fracture resistance at the zirconia component's edge line. Three edge line designs of the titanium base and zirconia sleeve were made: chamfer, shoulder, and backtaper...

The prosthetic component of dental implant is attached on the abutment which is connected to the fixture with an abutment screw. The abutment screw fracture is not frequent; however, the retrieval of the fractured screw is not easy, and it poses complications. A retrieval kit was developed which utilizes screw removal drills to make a hole on the fractured screw that provides an engaging drill to unscrew it. To minimize this process, the abutment screw is modified with a prefabricated access hole for easy retrieval...

Existing root-analog dental implant systems have no standardized protocols relative to retentive design, surface manipulation, or prosthetic attachment design relative to the site's unique anatomy. Existing systems historically made these design choices arbitrarily. For this report, strategies were developed which deliberately reference the adjacent anatomy, implant and restorable path of draw, and bone density for the purposes of implant and retentive design. For proof-of-concept, dentate arches from human cadavers were scanned with cone-beam computed tomography and digitally modeled...

Dentin-pulp complex regeneration is a promising alternative treatment for the irreversible pulpitis caused by tooth trauma or dental caries. This process mainly relies on the recruitment of endogenous or the transplanted dental pulp stem cells (DPSCs) to guide dentin-pulp tissue formation. Platelet-derived growth factor (PDGF), a well-known potent mitogenic, angiogenic, and chemoattractive agent, has been widely used in tissue regeneration. However, the mechanisms underlying the therapeutic effects of PDGF on dentin-pulp complex regeneration are still unclear...

INTRODUCTION: The specialty of periodontology has changed dramatically in recent years. With the long-standing goal of retaining teeth in a functional and esthetical state, the periodontology has developed a high level of expertise in the regeneration of bone and connective tissues that support the teeth. However, periodontists have also joined maxillofacial surgeons as the primary providers of implant surgery. METHODS: The tremendous innovations of periodontists induced also by the marketplace resulted in predictable periodontal treatment outcomes for most patients by the implants led to a dramatically different marketplace in which many patients with periodontitis can be treated by the implants rather than the traditional periodontal treatment...

Connective tissue grafting is a means of developing stable and natural-looking soft-tissue architecture. The use of a subepithelial connective tissue graft (SCTG) has been successful in achieving root coverage and augmenting tissue thickness. Tunnel techniques enable root coverage with results that appear natural. These techniques can be applied to the treatment of dental implants with gingival recession. The purpose of this article is to demonstrate the use of a SCTG and a lateral access pouch in the treatment of multiple gingival recession defects affecting adjacent implants...

OBJECTIVES: The etiology of the reduced marginal bone loss observed around platform-switched implant-abutment connections is not clear but could be related to the release of variable amounts of corrosion products. The present study evaluated the effect of different concentrations of metal ions released from different implant abutment couples on osteoblastic cell viability, apoptosis and expression of genes related to bone resorption. METHODS: Osteoblastic cells were exposed to five conditions of culture media prepared containing metal ions (titanium, aluminum, vanadium, cobalt, chromium and molybdenum) in different concentrations representing the amounts released from platform-matched and platform-switched implant-abutment couples as a result of an earlier accelerated corrosion experiment...
