Horizontal ridge augmentation using autogenous block grafts and the guided bone regeneration technique with collagen membranes: a clinical study with 42 patients

OBJECTIVE: To analyze the clinical outcome of horizontal ridge augmentation using autogenous block grafts covered with an organic bovine bone mineral (ABBM) and a bioabsorbable collagen membrane. MATERIAL AND METHODS: In 42 patients with severe horizontal bone atrophy, a staged approach was chosen for implant placement following horizontal ridge augmentation. A block graft was harvested from the symphysis or retromolar area, and secured to the recipient site with fixation screws. The width of the ridge was measured before and after horizontal ridge augmentation. The block graft was subsequently covered with ABBM and a collagen membrane. Following a tension-free primary wound closure and a mean healing period of 5.8 months, the sites were re-entered, and the crest width was re-assessed prior to implant placement. RESULTS: Fifty-eight sites were augmented, including 41 sites located in the anterior maxilla. The mean initial crest width measured 3.06 mm. At re-entry, the mean width of the ridge was 7.66 mm, with a calculated mean gain of horizontal bone thickness of 4.6 mm (range 2-7 mm). Only minor surface resorption of 0.36 mm was observed from augmentation to re-entry. CONCLUSIONS: The presented technique of ridge augmentation using autogenous block grafts with ABBM filler and collagen membrane coverage demonstrated successful horizontal ridge augmentation with high predictability. The surgical method has been further simplified by using a resorbable membrane. The hydrophilic membrane was easy to apply, and did not cause wound infection in the rare instance of membrane exposure.

Monitoring eines Hundes mit traumatischem Hämoabdomen durch serielle Messung von abdominalem und peripher venösem Hämatokrit

Objective: This case report describes the use of serial measurements of peripheral venous and abdominal fluid hematocrits as a guide to treatment in a dog with traumatic hemoabdomen. Material and methods: An 18-month-old, female mixed-breed dog was presented with traumatic hemoabdomen. The dog was treated with intravenous fluids, and concurrent measurements of venous and abdominal fluid hematocrits were performed. Results: The initial hematocrit values were 39% in venous blood and 42% in abdominal fluid. Following fluid therapy, the venous hematocrit decreased to 20%, whereas the abdominal hematocrit remained stable at 40%. Based on this finding severe ongoing intra-abdominal hemorrhage was ruled out, and the dog was treated conservatively. Conclusion and clinical relevance: Comparison of serial abdominal and venous hematocrits may be useful in assessing the need for surgical management in patients with traumatic hemoabdomen.

42'195 Meter ins Rampenlicht - Standortmarketing durch Marathonevents in Schweizer Städten

Mit der Durchführung von Sportevents werden vielfältige Hoffnungen verbunden. Unter anderem können Events Informationen über eine Destination transportieren und dadurch das zukünftige Verhalten von relevanten Zielgruppen wie Touristen oder Investoren beeinflussen. Die vorliegende Studie untersucht anhand von drei Marathonevents die Wechselwirkung zwischen Event und Destination sowie die Strategien zur Optimierung der positiven Effekte. Dabei zeigt sich, dass die Passung der Eventthematik zu den Destinationsschwerpunkten sowie der frühzeitige Einbezug aller relevanten Stake Holder Schlüsselrollen spielen. Alle drei betrachteten Marathonevents nehmen im Standortmarketing der jeweiligen Destination keine zentrale Rolle ein, sondern leisten in moderatem Umfang einen Beitrag zum Destination Branding.
