- PublicationMetadata onlyBiomechanical evaluation of malleable noncompression miniplates in mandibular angle fractures: an experimental study(2012-07-01) Esen, Alparslan; Dolanmaz, DOĞAN; Tuz, Hakan Hifzi; DOLANMAZ, DOĞANThe purpose of this experimental study was to test the reliability of a single malleable titanium miniplate using Champy-s method of fixing fractures of the mandibular angle. Eighteen sheep hemimandibles were used to evaluate 2 plating techniques. The groups were tested with either a single non-compression titanium miniplate or a single malleable titanium miniplate. A cantilever bending biomechanical test model was used for the samples. Each group was tested with vertical forces using a servohydraulic testing unit. The displacement values in each group at each 10 N stage up to 90 N were compared using 2-way analysis of variance (ANOVA). The displacement values for the 2 groups differed significantly (p < 0.01). The variance analyses showed that the biomechanical behaviour of a single non-compression miniplate was better than that of a single malleable miniplate. The non-compression miniplate fixed by screws had greater resistance to occlusal loads than the malleable plate fixed by screws, and the malleable plate alone was not sufficient to withstand the early postoperative bite force.

- PublicationMetadata onlyEffect of 2 flap designs on postoperative pain and swelling after impacted third molar surgery(2013-10-01) Dolanmaz, DOĞAN; Esen, Alparslan; Isik, Kubilay; Candirli, Celal; DOLANMAZ, DOĞANObjective. The aim of this study was to evaluate 2 flap designs (envelope and modified triangular flap) for postoperative pain and swelling after mandibular impacted third molar surgery.
- PublicationMetadata onlyHistological evaluation of effectiveness of platelet-rich fibrin on healing of sinus membrane perforations: A preclinical animal study(2017-08-01) Aricioglu, Ceyhun; Dolanmaz, DOĞAN; Esen, Alparslan; Isik, Kubilay; Avunduk, Mustafa Cihat; DOLANMAZ, DOĞANThe aim of this study was to evaluate the effectiveness of platelet-rich fibrin (PRF) in repairing of Schneiderian membrane perforations in rabbit maxillary sinus. A total of 42 female New Zealand rabbits were randomly divided into two groups. Symmetrical bony defects were created 1 cm in diameter and the sinus membranes were exposed. The Schneiderian membranes were elevated in both sinuses and each membrane was perforated with a 1 cm incision. No treatment was applied to the right perforations in both groups. Left-sided perforations were closed with collagen membrane in the first group and PRF membrane in the other group. Seven animals randomly selected from each group were sacrificed at weeks 1, 2 and 4 in order to be able to examine the amounts of lymphocytes, fibroblasts, veins, and collagen fibers in the area where the membranes were applied. Histological analyses showed that there were no statistically significant differences between the collagen membrane and the PRF membrane in the healing of sinus perforation area. PRF may be considered as an alternative application to collagen membrane in sinus membrane perforations. (C) 2017 European Association for Cranio-Maxillo-Facial Surgery. Published by Elsevier Ltd.

- PublicationMetadata onlyEvaluation of strain values of critical anatomic regions for two different pterygomaxillary approaches in Le Fort I osteotomy: An experimental study(2017-05-01) Ozdemir, Yusuf-Bugra; Dolanmaz, DOĞAN; Esen, Alparslan; Terzioglu, Hakan; Saglam, Haci; DOLANMAZ, DOĞANBackground: The purpose of this experimental study was to measure stresses both on the pterygoid plates and the skull base following two different pterygomaxillary approaches in Le Fort I osteotomy.
- PublicationMetadata onlyTreatment of localized langerhans- cell histiocytosis of the mandible with intralesional steroid injection: report of a case(2010-02-01) Esen, Alparslan; Dolanmaz, DOĞAN; Kalayci, Abdullah; Gunhan, Oemer; Avunduk, Mustafa Cihat; DOLANMAZ, DOĞANLocalized Langerhans cell histiocytosis (LLCH), formerly known as eosinophilic granuloma, mainly affects the skull, mandible, vertebrae, and ribs in children and the long bones of adults. Symptoms range from none to pain, swelling, and tenderness over the site of the lesion. General malaise and fever occasionally are present.
- PublicationMetadata onlyBiomechanical evaluation of different fixation systems after Le Fort I osteotomy in polyurethane models of unilateral clefts(2016-09-01) Esen, Alparslan; Isik, Kubilay; Saglam, Haci; Ozdemir, Yusuf Bugra; Dolanmaz, DOĞAN; DOLANMAZ, DOĞANWe compared the stability of three different titanium plate-and-screw fixation systems after Le Fort I osteotomy in polyurethane models of unilateral clefts. Thirty-six models were divided into 3 groups. In the first group, we adapted standard Plates 1 mm thick with 2.0 mm screws and placed them bilaterally on the zygomatic buttress and the piriform rim. In the second group, we did the same and added Plates 0.6 mm thick with 1.6 mm screws between the standard 2 mm miniplates on both sides. In the last group, we placed Plates 1.4 mm thick with 2.0 mm screws bilaterally on the maxillary zygomatic buttress and piriform rim. Each group was tested in the inferosuperior (IS) and anteroposterior (AP) directions with a servo-hydraulic testing unit. In the IS direction, displacement values were not significantly different up to 80 N, but between 80 and 210 N, those in the 2 x 1.4 mm group were better. In the AP direction, displacement values were not significantly different up to 40 N, but between 40 and 180 N, they were better in the standard with 1.6 x 0.6 mm group and the 2 x 1.4 mm group. When normal biting forces (90- 260 N) in the postoperative period are considered, the greatest resistance to occlusal loads was seen in the 2 x 1.4 mm group. In the others, the biomechanical properties were better in the AP direction. (C) 2016 The British Association of Oral and Maxillofacial Surgeons. Published by Elsevier Ltd. All rights reserved.
