Pre-autotransplantation alveolar process augmentation and premolar autotransplantation as a treatment method for single tooth replacement in adolescents.

The treatment of young patients with missing teeth and an atrophied alveolar process after trauma or agenesis of a tooth can be challenging. The aim of this study was to evaluate autotransplantation of a premolar after pre-autotransplantation alveolar process augmentation (PAPA) as a treatment option for these patients. A retrospective cohort study was implemented to analyse the PAPA procedure and subsequent autotransplantation procedure.

[Incision of the third molar in the Netherlands. Incision tech-niques for the removal of impacted third molars in the mandible.].

Various incision techniques to remove impacted third molars in the mandible have been described, for example, the flap incision, the envelope incision, the distal incision and the modified envelope incision. The aim of this study was to record the incision techniques used by oral and maxillofacial surgeons in the Netherlands for the removal of impacted third molars in the mandible. All members of the Dutch Association of Oral and Maxillofacial Surgery (NVMKA) received a questionnaire.

[The 3D printed drilling template for bilateral sagittal osteotomy].

The bilateral sagittal osteotomy (BSSO) is a widely used surgical technique within orthognatic surgery. The specific osteotomy design may vary from clinic to clinic. The best position of the bone cuts in a BSSO continues to be a point of discussion and probably differs from patient to patient.

Bilateral sagittal split osteotomy in cadaveric pig mandibles: evaluation of the lingual fracture line based on the use of splitters and separators.

Objective: To analyze the splitting pathways of the (lingual) fracture lines during a bilateral sagittal split osteotomy (BSSO) in cadaveric pig mandibles.

Study Design: A BSSO was performed using splitters and separators. Special attention was paid to end the horizontal medial cut at the deepest point of the entrance of the mandibular foramen.

[Automutilation of the palate in a psychiatric patient].

A 46-year-old man with a history of alcohol abuse was referred to an oral and maxillofacial surgeon with a large necrotic wound with raised edges on the palate. After history taking, radiography and clinical assessment, together with a psychiatrist, the lesion was diagnosed as an automutilation resulting from a period of alcohol abstinence. After a period of care in a medical centre, the lesion improved quickly.
