PURPOSE: To describe an unusual case of mandibular fracture after osseointegrated dental implant removal placed after inferior alveolar nerve transposition. REPORT OF CASE: The patient underwent inferior nerve transposition for implant placement due to lack of interarch space. Two months after metal-ceramic crowns installation, the patient began to complain of pain in the region of the implant. In an attempt to remove the implant, there was a fracture of the implant, and only two third of it was removed, leaving only the apical portion of the implant in the mandible...

PURPOSE: Investigating the effect of the combination of low-speed drilling and cooled irrigation fluid on intraosseous temperature rise during guided and freehand implant surgery. MATERIALS AND METHODS: Bovine ribs were used as bone specimens. Grouping determinants were as follows: drill diameter (2.0, 2.5, 3.0, and 3.5 mm), irrigation fluid temperature (10°C, 15°C, and 20°C), and surgical method (guided and freehand). Drilling speed was 800 rpm. Results were compared with previous ones using 1200 rpm...

BACKGROUND: Implant surgery in the mandible can cause serious complications that can be life threatening. The incidence and cause of iatrogenic trigeminal nerve injury (TNI) related to dental implant surgery was investigated in a survey of the opinion and experience of the UK dentists and reported by the authors in part 1 of this series of articles. Part 2 reported on the risk assessment and management of implant-related inferior alveolar nerve (IAN), mental nerve (MN), and lingual nerve (LN) injuries...

INTRODUCTION: Extremely atrophic maxillae can be considered the most important indication for three-dimensional maxillary reconstruction. Different bone-augmentation techniques have been suggested to accomplish this. This article illustrates a minimally invasive approach to rehabilitation of the extremely atrophic maxilla. MATERIAL AND METHODS: A 63-year-old male patient was referred for restoration of his totally edentulous maxilla with a fixed full-arch implant-prosthetic rehabilitation...

PURPOSE: Extensive bone defects in maxillofacial region can be corrected with autograft. However the disadvantages of this type of therapy lead to the search for new bone substitutes. Thus, we evaluated the biological behavior and osteoinductive platelet-derived growth factor type BB (PDGF-BB) associated with different carriers, by histological analysis and immunohistochemical histometric critical defects performed in rat calvaria. MATERIALS AND METHODS: Critical defects were created with 5-mm diameter calvaria of rats...

PURPOSE: To determine the effect of the cement type and abutment material on the tensile strength required to dislodge zirconia copings. MATERIALS AND METHODS: Two experimental groups of abutments were prepared: (1) titanium abutments (n = 30) and (2) zirconia abutments (n = 30). Sixty zirconia copings (custom designed) were fabricated using 3-dimensional computer-assisted design to have a 6-mm projection above the abutment to accommodate a hole, through which a wire was inserted to attach the zirconia coping to a universal testing machine...
