The placement of dental implants in atrophic jaws is a challenging procedure due to inadequate bone quantity. This anatomic limitation can be overcome by various treatment methods such as onlay bone graft, inlay bone graft (known as sandwich osteotomy), and distraction osteogenesis. Two female patients with complaints of atrophic mandible were included in this study.

Anterior mandibular zone safe for implants.

During implantology procedures, one of the most serious complications is damage of the inferior alveolar nerve (IAN). The mandibular incisive nerve is described as a terminal branch of the IAN and provides innervation to the lower anterior teeth and canines. The incisive nerve and canal are located in the interforaminal area.

Two case reports involving implants and fractured healing caps.

The widespread use of endosseous osseointegrated implants to replace missing natural teeth increases the chances of implant complications and failures, despite the high initial success rate reported in the literature. Implant and healing cap fracture are possible rare complications that can cause significant problems for both clinicians and patients. This article reports on 2 unique cases of implant and healing cap fracture, their possible causes, and how the cases were managed.

Maxillary sinus floor augmentation in patients with maxillary sinus pseudocyst: case report.

The maxillary sinus floor elevation procedure has gained popularity with predictable results, and is a safe, acceptable technique for bone augmentation, providing a base for dental implant treatment. Faint radiopaque lesions at the base of the maxillary sinus are frequent diagnoses on radiographs and must be identified during dental implant planning. Pseudocysts classically appear hemispheric, homogeneously opaque, and well delineated in panoramic and periapical radiographs.
