    Comparison of Success Rate of Dental Implants Placed in Autogenous Bone Graft Regenerated Areas and Pristine Bone
    (2020) Altiparmak, Nur; Akdeniz, Sidika Sinem; Diker, Nurettin; Bayram, Burak; Uckan, Sina; 32282668
    Autogenous bone grafting still has been considered as the "gold standard" and wildly used in the case of alveolar bone reconstruction. The aim of the present study is to evaluate the success rate of implants placed in autogenous block augmented ridges and implants placed in pristine bone (PB). This study included 113 patients. Fifty-three patients were treated with autogenous block grafts and particulate bone, after 6 months of healing implant placements were performed in autogenous bone augmented (ABA) areas. In 60 patients implant placement was performed, with no need for grafting and implants were placed into the PB. Follow-up data (pain, mobility, exudation from peri-implant space, success rate, marginal bone resorption) were collected after 5 years of prosthetic loading. The cumulative implant success rate at the 5-year examination was 92.45% for the ABA group and 85% for PB group. There were 3 failed implants in the ABA group and 3 in PB group. Average marginal bone loss was 1.47 mm on ABA group and 1.58 mm on PB group. No statistically significant differences for pain, exudation from peri-implant space, implant mobility, implant success, peri-implant bone loss parameters, and patient satisfaction level were found between groups. The obtained data demonstrated that the success rate of implants placed in regenerated areas are very similar to the success rate of implants those placed in PB.

    Sagittal skeletal correction using symphyseal miniplate anchorage systems: Success rates and complications
    (2019) Cubuk, Secil; Kaya, Burcak; Sahinoglu, Zahire; Ates, Ufuk; Ozcirpici, Ayca Arman; Uckan, Sina; 30413832
    ObjectivesAim of this study is to evaluate success rates and complications related with symphyseal miniplate anchorage systems used for treatment of Class2 and Class3 deformities.MethodsAtotal of 58miniplates applied to 29growing patients were evaluated. The first group comprised 24symphyseal miniplates applied to 12patients and Forsus Fatigue Resistant Devices were attached to the head of the miniplates for mandibular advancement. The second group consisted of 34symphyseal miniplates applied to 17patients and intermaxillary elastics were applied between acrylic appliances placed on the maxillary dental arch and the symphyseal miniplates for maxillary protraction. Success rate and complications of the symphyseal plate-screw anchorage system were evaluated.ResultsThe overall success rate of symphseal miniplates was 87.9%. Six miniplates showed severe mobility and 2miniplates broke during orthodontic treatment. Infection, miniplate mobility and mucosal hypertrophy were statistically different between the two groups.ConclusionsSymphyseal miniplates were generally used as successful anchorage units in most patients. Infection, mobility, and mucosal hypertrophy occurred more frequently in Class2 deformity correction. However, the success rates regarding the two treatment modalities were comparable. ZusammenfassungZieleZiel der vorliegenden Studie ist es, Erfolgsraten und Komplikationen im Zusammenhang mit symphysealen Miniplattenverankerungssystemen zur Behandlung von Klasse-II- und -III-Anomalien zu bewerten.MethodenAusgewertet wurden insgesamt 58Miniplatten, die bei 29Patienten im Wachstum inseriert wurden. In der ersten Gruppe wurden 24symphyseale Miniplatten bei 12Patienten inseriert. Zur Korrektur der Unterkieferrucklage wurden Forsus-Apparaturen an den Miniplatten verankert. In der zweiten Gruppe wurden 34symphyseale Miniplatten bei 17Patienten inseriert. Zur Protraktion des Oberkiefers wurden intermaxillare Elastics verwendet, die zwischen Acrylgeraten im Oberkiefer und den symphysealen Miniplatten eingehangt wurden. Untersucht wurden Erfolgs- und Komplikationsraten des symphysealen Platten-Schrauben-Verankerungssystems.ErgebnisseDie Gesamterfolgsrate der symphsealen Miniplatten betrug 87,9%. Bei 6Miniplatten zeigte sich eine hohe Mobilitat, 2frakturierten wahrend der kieferorthopadischen Behandlung. Das Auftreten von Infektion, Miniplattenmobilitat und Schleimhauthypertrophie war zwischen den beiden Gruppen statistisch unterschiedlich.SchlussfolgerungenSymphyseale Miniplatten wurden in der Regel bei den meisten Patienten als erfolgreiche Verankerungseinheiten eingesetzt. Infektion, Mobilitat und Schleimhauthypertrophie traten haufiger bei Klasse-2-Korrekturen auf, die Ergebnisse beider Behandlungsmethoden unterschieden sich jedoch nur geringfugig.

    Comparison of Tunnel and Crestal Incision Techniques in Reconstruction of Localized Alveolar Defects
    (2017) Altiparmak, Nur; Uckan, Sina; Bayram, Burak; Soydan, Sidika; 28520823
    Purpose: The aim of this study was to compare the complication rates of recipient sites prepared using two incision techniques: crestal and tunnel. Materials and Methods: In this prospective study, patients underwent augmentation procedures (68 patients; 75 sites) by the same surgeon that were performed consecutively using the crestal incision technique (27 horizontal, 10 vertical; crestal group) or the tunnel incision technique (27 horizontal, 11 vertical; tunnel group). Autogenous bone block grafts were harvested with a piezoelectric surgical device, and the grafts were fixed at the recipient sites by two titanium screws in both groups. The authors evaluated minor exposure, transient paresthesia, major exposure, permanent paresthesia, gingival recession at adjacent teeth, surgery time, and visual analog scale pain scores. Results: Soft tissue dehiscence and graft failure were significantly lower in patients undergoing the tunnel technique. Conclusion: The tunnel incision technique significantly decreased soft tissue exposure, the most common complication of augmentation procedures with autogenous onlay bone grafts. This technique should be considered an alternative to the crestal incision technique for preparation of the recipient site.
