The placement of dental implants in the anterior maxilla is a challenge for clinicians because of patients’ exacting esthetic demands and difficult pre-existing anatomy. This article presents anatomic and surgical considerations for these demanding indications for implant therapy. First, potential causes of esthetic implant failures are reviewed, discussing anatomic factors such as horizontal o...

Ahsttaet Recent advances in the technology of casting chrome-cobalt alloys for partiat denture frameworks has resulted in a technic for fabricating a custom-made mandibular implant during a single surgical appointment. The fabricating procedures are performed during the initial surgery and therefore eliminates the necessity of the patient undergoing a second surgical procedure for attachment of...

Capsular contraction is a frequent complication following breast augmentation. On the other hand, capsular weakness, a not widely recognized complication, may occur around the implant. A weak capsule allows the migration of the prosthesis to the lateral region of the thoracic region or inferiorly, towards the abdomen, due to gravitational forces. The cause of capsular weakness remains unresolve...

Research has shown that tooth loss results in morphological changes in alveolar ridge that may influence the subsequent implant placement. Immediate implant placement was introduced as a possible means to limit bone resorption and reduce the number of surgical procedures following tooth extraction. Histological and clinical evidence from human clinical studies showing efficacy of immediate impl...

Traditionally, the procedure of implant placement requires a surgical periosteal flap to be raised. In a percentage of implant cases, there is no need for flap surgery for implant placement, or for a follow-up surgical procedure for abutment connection. In this clinical investigation, 20 maxillary and mandibular implants were placed in seven adult male patients. The sites for implant placement ...

The implant periapical lesion (IPL), a possible cause for implant failure, may occur from the presence of pre-existing microbial pathology such as endodontic/periodontal lesions. This case report presents a case history related to IPL, which was caused by a pre-existing endodontic lesion. In addition, other possible causes such as surgical trauma and the management strategies of IPL are suggest...

objective: predoctoral dental implant education is included in dental school teaching curricula in most of the developed and some developing countries; however, it was not introduced into undergraduate curriculum of some countries and iranian dental schools. our purpose was to investigate the status of the predoctoral dental implant education of dental schools in the world. materials and method...

STATEMENT OF PROBLEM Surgical guides may interfere with effective use of surgical instrumentation during implant placement in the posterior segments where interocclusal distance may be limited. PURPOSE The purpose of this study was to measure and compare the accuracy of posterior implant placement using 3 precision surgical guides with varying occlusogingival heights, and to evaluate the diff...
