Background: Treatment of tooth loss with osseointegrated oral implants has a high success rate.<br />

However, placement of implants is frequently comprised or impossible due to atrophy of the alveolar<br />

process. Autogenous bone is generally the preferred gr<strong>af</strong>t material for reconstruction of the alveolar<br />

process and is usually harvested from the mandibular ramus. However the use of autogenous bone<br />

gr<strong>af</strong>ts is associated with the risk of donor site morbidity and complications.<br />

Purpose: The aim of the present study was to evaluate the morbidity and complications <strong>af</strong>ter bone<br />

harvesting from the mandibular ramus.<br />

Material and methods: 374 surgical procedures performed at The Department of Oral and Maxillofacial<br />

Surgery in Aalborg from the year 2000 to 2010 were retrospectively analysed based on records and Xrays.<br />

Data from records and X-rays was conducted according to registration sheet.<br />

Results: The frequency of temporary change in sensitivity was 5,9 % (n=22). The frequency of<br />

permanent reduced sensitivity was 0,5% (n=2). Hematoma occurred in 20 cases. Infection was<br />

registered in one case.<br />

Conclusion: The results of this study showed that bone harvested from the mandibular ramus is a s<strong>af</strong>e<br />

surgical procedure with few complications.<br />

Abstract<br />

Deviation <strong>af</strong> næseseptum ved SARME<br />

Formål: At undersøge om løsning <strong>af</strong> næseseptum i forbindelse med SARME operationer har betydning<br />

for postoperativ deviation <strong>af</strong> næseseptum.<br />

Materiale og metode: I alt 20 patienter indgik i undersøgelsen (M=9, F=11) Patienterne blev vilkårligt<br />

grupperet i to grupper. Gruppe I (n=10) med løsning <strong>af</strong> næseseptum og gruppe II (n=10) uden løsning <strong>af</strong><br />

næseseptum. På alle patienterne blev der foretaget CBCT optagelser umiddelbart før<br />

distraktionsprocessen og ved <strong>af</strong>sluttet distraktion. Opmåling blev foretaget i Dolphin Imaging 11.0.<br />

Målemetoden blev testet ved at opmåle samme 10 patienter 2 gange med en uges mellemrum.<br />

Resultater: Gruppe I: 4 patienter viste en deviation på > 1,5 mm. efter distraktion. Gruppe II 1 patient<br />

havde deviation på > 1,5mm. Metode studie viste en maximalt SD på 0,46 mm og et konfidensniveau<br />

95 % på maximalt 0,33 mm.<br />

Diskussion/konklusion: Nærværende undersøgelse viser at løsning <strong>af</strong> næseseptum er nødvendig i<br />

forbindelse med SARME. Imidlertid er den kliniske betydning for den øgede risiko for deviation <strong>af</strong><br />

næseseptum stadig uklar, men formentlig uden betydning. Der er med baggrund heri grundlag for<br />

yderligere undersøgelse, involverende en klinisk vurdering <strong>af</strong> næseseptum<br />
