Despite the high success rates and stability of dental implants, failures do occur. While surgical trauma together with bone volume and quality are generally believed to be the most important etiological factors for early implant failures, the etio logy of late failures is more controversial. Early detection and treatment of early progressive bone loss around dental implants by mechanical debri...

Aim. To investigate whether there is a correlation between early dental implant failure and low serum levels of vitamin D. Methods. All patients treated with dental implants in a single centre, in the period 2003-2015, were considered for enrollment in this study. The main outcome was early implant failure. The influence of patient-related variables on implant survival was calculated using the ...

Oral movement disorders may lead to prosthesis and implant failure due to excessive loading. We report on an edentulous patient suffering from drug-induced tardive dyskinesia (TD) and oral parafunction (OP) rehabilitated with implant-supported screw-retained prostheses. The frequency and intensity of the movements were high, and no pharmacological intervention was possible. Moreover, the patien...

This article reports the 4-year interim results of a multicenter study evaluating the clinical performance of the Osseotite dental implant. At 4 study centers, 485 Osseotite implants were consecutively placed in 181 patients (219 were placed in the mandible and 266 in the maxilla). A total of 355 implants were placed in posterior regions. Short implants (10 mm or less) represented 31.5% (n = 15...

Purpose: To evaluate long-term clinical performance of 1-stage dental implant prostheses at a single clinic, emphasizing clinical and demographic characteristics that affect implant survival. Materials and Methods: Dental records of all 308 patients (674 implants) treated with 1-stage implants at Mayo Clinic from October 1993 through May 2000 were reviewed from implant placement to last visit. ...

Although dental implants have become a predictable aspect of tooth replacement in prosthodontic treatment [1, 2, 3, 4, 5, 6], failures of up to 10% are still encountered. Furthermore these failures have been more associated with “soft” bone quality [7], 1985) such as encountered in the maxillary posterior area [8, 9, 10, 11, 12]. In a review article by Esposito et al [13], bone quality and volu...

The article demonstrates the factors of importance in the early and late failures of dental implants based on literature review. An implant location is one of many factors that can influence a success or failure of dental implants. The author identifies and describe four alveolar jaw regions--functional implant zones--with unique characteristics of anatomy, blood supply, pattern of bone resorpt...

BACKGROUND Few large-scale follow-up studies are reported on routine implant treatment. PURPOSE To report retrospective data on early inflammatory and early implant failures in a large number of routine patients at one private referral clinic. MATERIALS AND METHODS A total of 1017 patients were consecutively provided with 3082 implants with an anodized surface (Nobel Biocare AB) at 1592 imp...
