Lateral view, much of the spongious part was removed so there was a gap between residual bone and graft. ticalaugmentation.Outofthese24blocks,twowere a failure due to soft tissue exposure and thus com- pletely removed. The remaining blocks were loaded with 38 implants at later stages and all implants achieved good primary stability. Contar et al.9 also published their paper in 2009. A total of 34 osseous allogenic blocks were used in 15 patients, one block hadanearlyexposure.Anumberof51implantswere placed into the grafted area with sufficient primary stability.Noneoftheimplantswerelostwithinanob- servation period between 24 to 35 months. Carinci et al.10 published a paper in 2010 where implants placed in the resorbed maxilla, which had been graftedwithosseousallogenicblocksandreporteda survival rate of 98.3 % over a mean follow-up of 26 months. This study showed results comparable to same areas augmented with autologous iliac crest bone.11 In 2015, Krasny et al.12 published an article in which21patientsweretreatedwith26grafts.Intwo grafts,therewerecomplicationswithsofttissue,and one augmentation had to be redone because of iat- rogenic causes. After three to six months of healing, 33implantswereplaced.Withinanaverageobserva- tiontimeof36months(28–50),noimplanthadbeen lost. Araujo et al.13 published a systematic review on the same matter in 2013, in which a total of 253 os- seous allogenic blocks were placed in 194 patients with a mean follow-up of twelve months (3–66). All studies showed good success from 95 % to 100 %. Materials and methods Atotalof15Patientsweretreatedbythesamesur- geon in Godt Smil Odense from November 2013 to March2015.NinePatientsweremale,sixwerefemale. The youngest patient is 26 and oldest patient is 78-years-old.These15patientsreceived19allogenic bone blocks to horizontally augment the atrophic al- veolarprocessbothinthemandibleandinthemaxilla prior to implant placement. All patients were in good general health, one was a smoker. All patients under- went periodontal therapy, if needed, before surgical intervention. Surgical procedure Premedication is 2,000 mg Imadrax (Amoxicillin), 1,000 mg Pinex (Paracetamol) and 400 mg Ibumetin (Ibuprofen)60minutesbeforetreatment.AllPatients were instructed to rinse their mouth with 0.05 % Chlorhexidine solution twice for one minute. The samestrengthofchlorhexidinesolutionwasusedfor the perioral skin using a chlorhexidine-impregnated gaze. Local anaesthesia was administered as infiltra- tionbuccallyandpalatally/lingually(Xyloplyin®den- tal adrenalin 20 mg/ml + 12.5 microgram/ml lidocain hydrochlorid + adrenalin, DENTSPLY). Venous blood was sampled with a so-called butterfly (Vacuette® Greiner bio-one). The blood was collected in 10 ml Fig. 6 Fig. 7 Fig. 8 Fig. 9 Fig. 10 Fig. 11 Fig. 12 Fig. 13 Fig. 14 Fig. 15 Fig. 16 Fig. 17 42016
