Fourier and fractal analysis of maxillary alveolar ridge repair using platelet rich plasma (PRP) and inorganic bovine bone.

This report concerns the regeneration of the maxillary alveolar process in a 17-year-old patient who had lost the upper central incisors together with alveolar bone as a result of a car accident. Three months later, GBR (guided bone regeneration) was started with the use of autogenic platelet rich plasma (PRP) and inorganic bovine bone. The regenerated bone was analysed after 10 months and compared with intact bone using Fourier analysis of radiograms.

[Haemorrhagic cyst of the masseter--case report].

Tumour-like changes in the masseter may be diagnosed as haemangiomas, lymphomas, lipomas, hernia of the muscle, benign hypertrophy or inflammatory or traumatic lesions. The authors describe a case of haemorrhagic cyst of rare location in the masseter and analysed the clinical features of this lesion.
