[Position paper on medication-related osteonecrosis of the jaw (MRONJ)].

It is now 12 years since the first article on medication-related osteonecrosis of the jaw (MRONJ) was reported in 2003. The recognition of MRONJ is still inconsistent between physicians and dentists but it is without doubt a severe disease with impairment of oral health-related quality of life. This position paper was developed by three Austrian societies for dentists, oral surgeons and osteologists involved in this topic.

Case report: fusion of positron emission tomography (PET) and computed tomography (CT) images for image-guided endoscopic navigation in maxillofacial surgery: clinical application of a new technique.

Introduction: Surgery based on computed tomography (CT) data is becoming increasingly important in the head and neck region. The technique for hardware fusion between positron emission tomography (PET) and computed tomography (CT) has only been established commercially in the last 4 years. The advantages over CT alone are obvious.

[Effects of Le-Fort-I-Osteotomy on nasalance scores].

Background: Nasalance represents a measure of the relative amount of oral and nasal acoustic energy produced by a speaker. Literature shows changes in nasalance after surgery of the oropharynx. The aim of this prospective study was to evaluate the outcome of speech and nasalance scores after Le-Fort-I-Osteotomy.

Anterior transmandibular osteodistraction: clinical and model observations.

Introduction: The aim of this paper was to study the effect of transmandibular distraction on the periodontal and dental structures, and the initial movements of the mandibular halves, when using an axial plane non-rigid bone-borne distractor (TMD).

Material And Methods: Fourteen patients undergoing bimaxillary transverse osteodistraction had their six lower anterior teeth assessed for mobility, sensitivity, and pocket depth. Recordings were made pre-operatively, post-distraction, post-consolidation and at 1-year follow-up.
