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.

Anatomical characteristics of maxillary sinus septa visualized by cone beam computed tomography.

Proper implant positioning in the posterior region of the edentulous maxilla commonly requires sinus floor elevation. Maxillary sinus septa increase the risk of membrane perforation during sinus floor elevation. The purpose of this retrospective, cone beam computed tomography (CBCT)-based study was to examine the frequency, number, location, and orientation of antral septa in the maxillary sinus.

Total virtual workflow in CAD-CAM bony reconstruction with a single step free fibular graft and immediate dental implants.

The Surgical reconstruction of defects of the face is challenging. Local and regional flaps have an important part to play, but large defects of bone and soft tissue are a greater problem. Microvascular tissue transfer has become the standard for such patients, and preoperative planning of bony reconstructions is now common.

Outcome of Surgically Treated Fractures of the Condylar Process by an Endoscopic Assisted Transoral Approach.

Purpose: Fractures of the condylar process are frequent. Ideal management of these fractures, as discussed in the literature, is controversial. Some recent meta-analyses have favored open reduction and internal fixation using various approaches.

Cone Beam Computed Tomography Evaluation of the Artery in the Lateral Wall of the Maxillary Sinus: Retrospective Analysis of 602 Sinuses.

Purpose: This retrospective study evaluates the location of the arteries in the maxillary sinus, particularly in the middle portion, using cone beam computed tomography (CBCT) scans that can detect the lateral arteries with high reliability.

Methods: In this retrospective study, 2 experienced independent examiners evaluated 602 sinuses on CBCT scans.

Discussion: No significant correlation was found between the location of arteries and the patient's age, sex, or dentition.

[Therapeutic options to manage bleeding in a dentist’s office].

This manuscript provides an overview of therapeutic options for the problem of bleeding in a dentist’s office. Bleeding after tooth extraction is a very common finding in dental medicine and persistent blood in the mouth is obviously uncomfortable and sometimes terrifying for the patient. Most bleedings can be stopped simply with compression, in some cases a homeostatic therapy is necessary.

Intraoperative 3-dimensional cone beam computed tomographic imaging during reconstruction of the zygoma and orbit.

Objective: Fractures of the zygoma and orbit are common facial skeleton injuries. Inadequate reduction and internal fixation may result in functional and aesthetic impairment. The aim of this study was to assess the use of intraoperative 3-dimensional (3-D) cone beam computed tomography (CBCT) for determining the intraoperative revision rate and the need for additional reconstruction of the orbit.

3D-evaluation of the maxillary sinus in cone-beam computed tomography.

Background: There are few studies measuring the dimensions of the maxillary sinus, being mostly based on computed tomography imaging and rarely being based on cone-beam computed tomography (CBCT). The aim of this study was to measure the 3D osseous and soft tissue defined volume and surface area of the maxillary sinus. Further, possible associations with patient-specific and sinus-related variables were evaluated.

Retrospective analysis of 471 surgically treated zygomaticomaxillary complex fractures.

Purpose: Zygomaticomaxillary complex (ZMC) fractures are frequent in facial trauma; only fractures of the mandible are more common. Although the frequency of these fractures is geographically consistent, the aetiology differs widely among countries and even regions. Differences in socio-economic status and the ageing population seem to be two causes.

[The organ transplanted patient in the dental clinic].

Patients with solid organ transplants can be challenge to manage pre- and postoperatively. Dental care should be given to these patients prior to surgery in order to achieve healthy oral conditions. Periodontitis has to be treated, in- sufficient root canal treatments need to be revised, cavities shall be filled and teeth that cannot be salvaged should be extracted.

Use of a monopolar microneedle device in a transconjunctival, retroseptal approach.

Transconjunctival approach is a standard procedure to address fractures of orbit and the infraorbital rim. Modifications such as transcaruncular or lateral canthal widening allow for extended orbital wall exposure. Especially concerning aesthetics, the transconjunctival approach shows benefits compared to the transcutaneous incisions, such as the transciliary and infraorbital access.

Denosumab as a Treatment Alternative for Central Giant Cell Granuloma: A Long-Term Retrospective Cohort Study.

Purpose: Giant cell granuloma (GCG) of the jaw is a rare disease with high morbidity. Various treatment options have been discussed in the past. Since 2010, a pharmaceutical therapy with denosumab seems to have been successful for giant cell tumors of the femur.

[Amoxicillin with clavulanic acid - standard antibiotic in general dentistry].

This script gives a pragmatic advice for gen-eral dentists on accurate use of amoxicillin with clavulanic acid considering current liter-ature at acute inflammatory disease. In ab-sence of contraindications a twice daily for- mulation of 1g amoxicillin with clavulanic acid is the first choice for concomitant therapy after treating the cause of inflammation or prophy-laxis. Compared to clindamycin the concen-tration of amoxicillin in teeth and bone (Hallig 2014) is higher and has less gastrointestinal side-effects (Bax 2007).

Oral lichen planus is a relatively common T-cell mediated inflammatory disease with potential malignant transformation. It may present itself with pain and oral lesions such as ulcers and Wickham’s striae. Treatment includes topical corticosteroids, preferably Clobetasol, immunosuppressive drugs and retinoids.

[Not Available].

This script gives a pragmatic advice for dentists on pain control and anti-inflammation treatment considering current literature and state of the art of analgesic treatment. Naproxen seems to be the feasible anti-inflammatory painkiller as it has a lower cardio-vascular risk profile compared to other NSAID. The higher gastrointestinal bleeding risk can be mitigated using proton-pump inhibitors.

The Effects of Preoperative Radiotherapy on Head and Neck Free Flap Anastomosis Success.

Purpose: The long-term survival benefit of neoadjuvant radiotherapy for oropharyngeal tumors is controversially discussed in the literature. To bring more light into this important debate, we evaluated our cases.

Patients And Methods: In this retrospective study the main focus was the relationship between neoadjuvant irradiation and anastomosis failure.

Inferior alveolar nerve function after open reduction and internal fixation of mandibular fractures.

Purpose: Mandibular fractures are amongst the most common facial fractures and are usually treated by open reduction and internal fixation (ORIF). Inferior alveolar nerve (IAN) injuries are seen frequently in mandibular fractures as well as after ORIF of these fractures due to the exposition and the close proximity of the nerve during fracture reduction. Therefore the continuity of the IAN can be disrupted.
