Associated Ophthalmic Injuries in Patients With Fractures of the Midface.

Purpose: Concomitant ophthalmic injuries are common in patients with facial fractures, though frequency varies widely in the literature. Major ophthalmic injuries can have drastic consequences for patients, and permanent visual impairment cannot be prevented in all cases. This study analyzed the frequency and distribution pattern of associated ophthalmic injuries in patients who received operative treatment for fractures of the midface.

[Conduction anesthesia of the infraorbital nerve - A guide to intraoral nerve block anesthesia of the infraorbital nerv].

In order to be able to perform major oral surgery in the upper jaw, sufficient local analgesia is indispensable. While the inferior alveolar nerve is often blocked for dental treatments in the lower jaw, block anesthesia in the upper jaw is less common. This article gives pragmatic advice on how to block the infraorbital nerve.

Precision of 30 guided implants in complex tumour situations.

Implant born prosthetic rehabilitation of tumour patients can be difficult to perform. Challenges in treating such patients include disrupted anatomy with limited mouth opening due to previous ablative surgery as well as free-flaps or simple bone grafts, adjuvant therapy such as radiotherapy and, in general, poorer general health. Combining classical knowledge of ideal prosthesis placement and current virtual planning possibilities the positioning and in consequence the survival of dental implants can be optimised.

Accuracy of Computer-Guided Template-Based Implant Surgery: A Computed Tomography-Based Clinical Follow-Up Study.

Objective: The aim of this clinical study was to analyze the accuracy of computer-guided implant surgery.

Materials And Methods: Assisted by computed tomography (CT)-based planning software and navigational templates, 16 patients successfully received 26 dental implants. Each implant parameter (a-d) was calculated based on superimposed preoperative and postoperative cone beam CT scans: (a) deviation at entry point; (b) deviation at apex; (c) angular deviation; and (d) depth deviation.

Precision of Simultaneous Guided Dental Implantation in Microvascular Fibular Flap Reconstructions With and Without Additional Guiding Splints.

Purpose: Dental rehabilitation in patients receiving free flap reconstructive surgery on the mandible or maxilla is an important part of bringing patients back to normality in both a physical and psychological way. It is therefore important to be able to do this in the fastest way possible. Virtual preplanned reconstructions of jaws with implants placed simultaneously are a good way to expedite this process and have the advantage of allowing true backward planning to achieve bone placement where it prosthetically needs to be.
