Atypical Implant Failure
Journal Title: Modern Approaches in Dentistry and Oral Health Care - Year 2018, Vol 1, Issue 1
Abstract
With an average survival rate of 95%, the endosseous dental implant is one of the most successful and predictable innovations in modern dentistry. The factors contributing to the success, and failure, of dental implants are now well-established [1-6] and include the oral and systemic health of the patient, patient age, implant type, implant surface, implant length, bone type, surgical site (mandible or maxilla), type of surgery (one- or two-stage) and immediate (fresh socket) or delayed implant placement. Other important aspects regarding the success of an implant include the skill, experience and, apparently gender, of the surgeon [7]. Early implant failures, a prevalence of about 5.6%, most often is observed in edentulous upper jaws, notably with implants having a turned surface. There is some controversy as to whether pre- and post-operative antibiotic coverage is needed, but overall antibiotic therapy can be helpful but apparently is only essential when infection is present. A healthy, well-nourished 76 year old man without systemic or oral diseases presented with missing teeth in tooth positions #18 and #19. The patient previously had successful implant surgery together with a sinus lift in the maxilla some years prior to the present surgery. The patient had no history of metal allergies and satisfied the selection criteria for successful implant surgery Pre-operative radiographs, Figure 1, showed that the bone at the surgical site was compact and well-vascularized. The satisfactory bone conditions at the implant sites were confirmed by CT scan. After fabrication of a placement template for the implants, sockets for the implants was prepared using the Nobel Biocare tapered osteotomy drill kit, utilizing the 2 mm twist drill, the 3.5 mm drill, the 4.3 mm drill and the 4.3 mm dense bone drill.
