A retrospective analysis of autotransplanted teeth including an evaluation of a novel surgical technique.

Objectives: To assess survival rates and frequency of complications for immature and mature autotransplanted teeth after at least 1 year in function.

Materials And Methods: All consecutive patients who had undergone tooth autotransplantation between 2000 and 2018 were invited to a clinical and radiographic follow-up examination. First, survival rates were calculated on the basis of a phone inquiry.

Analysis of trends in implant therapy at a surgical specialty clinic: Patient pool, indications, surgical procedures, and rate of early failures-A 15-year retrospective analysis.

Objectives: To evaluate the patient population over a 3-year period and to compare it to observations of the population at the same clinic over a period of 15 years.

Material And Methods: Records of patients receiving dental implants in the Department of Oral Surgery and Stomatology, University of Bern, between January 2014 and December 2016 were analyzed and then compared with data from patients treated between 2002 and 2004 and between 2008 and 2010. Patients were analyzed for demographics and for indications for therapy, as well as for presence or absence and type of complications.

Distances of root apices to adjacent anatomical structures in the anterior maxilla: an analysis using cone beam computed tomography.

Objectives: The aim was to assess the anatomical relationship of anterior maxillary teeth to the nasal floor in patients referred for apical surgery.

Materials And Methods: Cone beam computed tomographic images (CBCT) of 83 patients were analysed retrospectively to quantify the distances between the root apices of maxillary anterior teeth (canine to canine) to the nasal floor or maxillary sinus (whichever was closer). Secondary outcome variables were the distances of the periapical lesion to the nasal floor, distances of the apices to the labial and palatal bone plates as well as to the neighbouring teeth.

[Osseous dysplasia: an incidental radiological finding].

Osseous dysplasias (OD; formerly known as cemento-osseous dysplasias) are idiopathic changes in the area of the tooth-bearing alveolar process. The normal bone structure is replaced by fibroblasts and collagen fibres and later by mineralized tissue and bone. In the current WHO classification, ODs are categorized as bone-associated lesions or non-neoplastic, fibro-osseous lesions of the head and neck region.

Assessment of the nonoperated root after apical surgery of the other root in mandibular molars: a 5-year follow-up study.

Introduction: If a surgical approach is chosen to treat a multirooted tooth affected by persistent periapical pathosis, usually only the affected roots are operated on. The present study assessed the periapical status of the nonoperated root 5 years after apical surgery of the other root in mandibular molars.

Methods: Patients treated with apical surgery of mandibular molars with a follow-up of 5 years were selected.
