dc.description.abstracteng Purpose: In order to achieve good long-term results from dental implant therapy a sufficient amount of bone is needed around the correct implant position. Therefore, various procedures were introduced to augment the horizontally deficient mandibular ridge. The Upside Down Cylinder Technique makes use of localized autologous bone transfer in order to prevent the otherwise inevitable grafting procedure. In this retrospective study, clinical results and oral health related quality of life (OHRQoL) are being reported. Method: 44 Patients received horizontal bone augmentation and 29 Patients (22 female, seven male) with 43 implants could be followed up (dropout rate 34 %). The mean observation time was 93,6 +/- 36,3 months. Periimplant bone resorption (PBR), implant stability, periodontal probing depth (PPD), gingival recession (GR), implant survival, implant success and the state of OHRQoL were evaluated, respectively. Results: Within the observation period two implants were lost due to biological complications. This study shows an implant survival rate of 93 %. The implant success rate was 88,1 % according to Jahn/d’Hoedt criteria and 76,2 % according to Naert/Snauwaert criteria regarding patient level observation. Mean PBR was 2,57 +/- 1,93 mm, PPD accounted to 2,68 +/- 0,91 mm and GR was 0,75 +/- 1,26 mm. In order to assess patients OHRQOL, the Oral Health Impact Profile (OHIP) was used. Separated by prostetic indication classes, patients with installed FPD scored 9,2; patients with implant retained removable partial dentures and total prostheses scored 15,5 and 17,3; respectively. Corresponding scores were 30, 20 and 20 percentiles higher than median of reference values from non - treatment - seeking patients Conclusion: Upside Down Cylinder Technique delivers comparable implant long-term results compared to other autologous augmentation procedures without having to raise a flap for bone grafting. OHRQOL was high compared to reference values from non - treatment - seeking patients. Patients satisfaction and recommendation was also high. This study suggests a higher success rate in the posterior mandibular ridge. de
