How expensive is vole damage?

Vole species, especially Arvicola terrestris and Microtus arvalis cause significant economical damage in organic pomiculture by gnawing the root system of trees. The importance of voles as pest organisms is well known. Nevertheless, the estimation of financial loss caused by voles is difficult for German fruit growers. We conducted a survey among organic fruit growers to get data on kind and amount of annual damage. Using the available publications and official statistics we calculated economical values of organic apple trees for different types of orchard processing and tree ages. Furthermore we calculated the number of trees lost due to voles in one year

Migrationsbarrieren gegen Wühlmäuse – Erfahrungen aus 3 Jahren Praxiseinsatz

In der landwirtschaftlichen Praxis wird die Wühlmausbekämpfung vorrangig mit Fraßködern, Fallen und Begasungsgeräten durchgeführt. Um die Besiedlung wühlmausfreier Flächen zu verhindern werden seit 2002 Migrationsbarrieren in der obstbaulichen Praxis erfolgreich erprobt

Wie teuer sind Wühlmausschäden im ökologischen Obstbau?

Durch das Benagen von Baumwurzeln verursachen Schermäuse (Awicola terrestris) und Feldmäuse (Microtus awalis) bedeutende Schäden im Obstbau

Maxillary distraction osteogenesis: A method with skeletal anchorage

Maxillary distraction osteogenesis is a challenging technique to treat severe maxillary retrusion. Maxillary advancement by distraction has the advantage to provide new bone in combination with simultaneous expansion of the soft-tissue functional matrix. Cleft lip and palate patients can present with severe maxillary retrusion and Class III malocclusion. Two 13-year-old patients, born with nonsyndromic cleft lip and palate, underwent maxillary distraction - one had a bilateral, the other a unilateral complete cleft lip and palate. Maxillary advancement was performed using an external distraction device in combination with titanium miniplates as a skeletal maxillary anchorage. After a complete Lefort I osteotomy with pterygomaxillary disjunction, a latency period of 3 days was respected. On the fourth postoperative day, distraction was initiated at the rate of 1 mm/d. Preoperative clinical photographs, dental casts, lateral cephalograms, and panoramic radiographs were taken. Further lateral cephalograms were obtained after the latency period, after completion of the active period of distraction, at the completion of the consolidation period, and at 6 and 12 months postoperatively. The aesthetic outcome was excellent and skeletal advancement of 8 and 7 mm was measured without dentoalveolar compensations.SCOPUS: ar.jinfo:eu-repo/semantics/publishe

Use of an onplant as orthodontic anchorage

Considerable limitations in the clinical application of orthodontic treatment can result from the lack of teeth suitable for anchorage. If prosthetic rehabilitation is necessary, endosseous implants can be first used as orthodontic anchorage and then loaded by a prosthetic superstructure. However, in a plan of exclusive orthodontic treatment, alveolar bone is not always available, and an orthodontic osseointegrated anchorage system might be necessary. We report the use of an onplant for palatal anchorage to extrude the unerupted horizontal maxillary first molars in a 12-year-old white girl with tooth aplasia and secondary cleft palate. After a healing period of 5 months, the onplant remained stable under indirect elastic tension of approximately 160 g applied for 17 weeks, and the maxillary first molars were successfully extruded.

Neurosensory disturbances after immediate loading of implants in the anterior mandible: An initial questionnaire approach followed by a psychophysical assessment

The aim of the study was to assess past and present neurosensory disturbances using a questionnaire and a psychophysical approach in patients treated with immediate loaded implants in the edentulous anterior mandible. A group of 65 patients (age range 30-84 years, mean 58 years, 30 women) was enrolled. All were treated by means of three immediately loaded implants (Branemark Novum System®). A self-designed questionnaire was used for data collection. The response rate was 89%. Of the 58 responders, 33% (n =19) reported neurosensory disturbances after implant surgery. Nine of these patients (mean age 56 years, seven women) participated in an objective evaluation and were subjected to a psychological and several psychophysical tests. At the moment of the evaluation none of the nine patients still had clinical complaints. Psychological testing revealed no statistical differences between the patients, who had previously experienced subjective complaints, and the control group. Two-point discrimination and thermal sensation tests revealed no sensory lesions. The light touch sensation test at the lower lip indicated a more frequent reduction of tactility for the test group (p≤0.03). Neurosensory disturbances can occur in the anterior region of the mandible after implant surgery. © Springer-Verlag 2006.SCOPUS: ar.jinfo:eu-repo/semantics/publishe

Maxillary distraction in cleft lip palate patients: A review of six cases

Cleft lip and palate patients can present with a maxillary retrusion with tendency to Class III malocclusion after cleft repair. Maxillary distraction osteogenesis is a technique that provides simultaneous skeletal advancement and expansion of the soft tissues. Six nonsyndromic cleft lip and palate patients, ages 12 to 16 years (mean, 13.8 years), underwent maxillary distraction; four had a unilateral and two a bilateral cleft lip and palate. After an incomplete LeFort I osteotomy, a latency period of 3 days was respected. On Postoperative Day 4, distraction was initiated through anterior traction on a Delaire facial mask using distraction forces of 900 gm. Photographs and lateral cephalometric radiographs were obtained preoperatively and 4 months after distraction. A cephalometric analysis was performed to compare the sagittal dentocraniofacial morphology before and after distraction. The aesthetic improvement obtained by maxillary distraction osteogenesis during the permanent dentition to correct maxillary retrusion in our cleft lip and palate patients was impressive. Skeletal advancement varying from 1 to 3.5 mm (mean, 1.7 mm) was found. However, significant dentoalveolar compensations occurred in three patients. This was due to the dental anchorage of the distraction device and can be avoided only by the use of skeletal fixation.SCOPUS: ar.jinfo:eu-repo/semantics/publishe
