Diabetes mellitus (DM) is considered one of the major chronic diseases in the world. Long-term hyperglycemia considerably affects the body tissues, and consequently, can lead to morbidity and mortality. Moreover, many oral complications have been observed with DM but little consideration in relation to the placement of dental implants has been investigated. Dental research has analyzed the relation of dental implants and bone osseointegration in diabetic patients. Theoretically, an impaired immune system and delayed wound healing of these patients might decrease the success rate of implant placement; however, with noticeable advances in evidence-based dentistry and statistically significant results, successful implant treatment could be achieved significantly in well-controlled diabetic patients...

Dental implant surgery has developed to a widely used procedure for dental rehabilitation and is a secure and predictable procedure. Local and systemic risk factors can result in higher failure rates. Diabetes mellitus is a chronic disease that goes in with hyperglycemia and causes multifarious side effects. Diabetes as a relative contraindication for implant surgery is controversially discussed. Because the number of patients suffering from diabetes increases, there are more diabetic patients demanding implant procedures...

Dental implants with their increasing success rates and predictability of final outcome are fast becoming the treatment of choice for replacing missing teeth. Considering the success of immediate implant placement in reducing tissue loss and achieving good esthetic results, is making it a more popular treatment modality in implant dentistry. Understanding the management of gingival tissues in relation to implants to obtain maximum esthetics is of utmost importance. The use of provisional abutments and immediate temporization has a proven track record of their ability to produce optimal esthetics and to guide the tissue response during the healing phase...

The dental implant is a predictable way of restoring fully and partially edentulous patients and has shown high success rate for managing a broad range of clinical conditions. Improving implant surfaces has revolutionized the osseointegration of implants and changed the focus of implant research from osseointegration more toward the risk factors associated with the failure of implants in the long-term.

PURPOSE: To report the outcome of graftless osteotome sinus floor elevation (OSFE) in order to evaluate whether apical bone gain depends on the initial residual bone height and whether the initial residual bone height has an influence on the amount of marginal bone loss. Furthermore the study aimed to assess if perforations of the Schneiderian membrane or residual bone height are potential predictors of implant survival. MATERIALS AND METHODS: In this retrospective study all patients were included who were treated between 2001 and 2010 and received dental implants in combination with OSFE in a private practice...

Osteoporotic patients have a high risk of dental and orthopedic implant failure. Lithium chloride (LiCl) has been reported to enhance bone formation. However, the role of LiCl in the success rate of dental and orthopedic implants in osteoporotic conditions is still unknown. We investigated whether LiCl enhances implant osseointegration, implant fixation, and bone formation in osteoporotic conditions. Sprague-Dawley female rats (n = 18) were ovariectomized (OVX) to induce osteoporosis, and another nine rats underwent sham surgery...

A sample of 24 patients with varied morphologic defects were treated with 34 titanium meshes and particulate bone and rehabilitated at least 8 to 9 months thereafter with the placement of 88 implants. Of the 34 meshes, 4 had to be removed before implant placement (11.76% total failure) and 20 were exposed due to soft tissue dehiscence (58.82% of complications): 4 (11.77%) prematurely (within 4 to 6 weeks) and 16 (47.05%) delayed (after 4 to 6 weeks), with no compromise in implant placement. None of the 88 implants was lost (100% implant survival), and 15 demonstrated increased bone loss, yielding a cumulative implant success rate of 82...

A central dental implant success criterion is the marginal bone response as measured longitudinally. Factors that influence marginal bone changes include osseous and soft tissue architecture, occlusal loading factors, implant position, implant design, and inflammatory processes. The evolution of implant design is multifactorial and includes the implant-abutment interface geometries. The primary objective of this study was to compare the proximal marginal bone changes following placement and loading of internal conus design implants (ICI) and external hex design implants (EXI) used in the treatment of posterior partial edentulism...
