Article Citation Count: 11Effects of hyperbaric oxygen treatment on implant osseointegration in experimental diabetes mellitus(Univ Sao Paulo Fac Odontologia Bauru, 2018) Erdoğan, Özgür; Tatli, Ufuk; Coskun, Abdullah Tugrul; Erdogan, Ozgur; Ozkan, Aydin; Sencimen, Metin; Kurkcu, Mehmet; Ağız,Diş ve Çene Cerrahisi / Oral, Dental and Maxillofacial SurgeryObjective: To evaluate whether hyperbaric oxygen (HBO) treatment has a favorable effect on implant osseointegration in diabetic rabbits. Material and Methods: An experimental diabetes model was induced in 32 New Zealand rabbits through IV injection of alloxan. After the state of diabetes had been confirmed, one dental implant was placed in the metaphysical region of each animal's tibia. After the implants' placements, the animals were divided into two groups. Half of the animals underwent HBO treatment, while the other group did not receive HBO treatment and served as the control group. The animals were euthanized at the 4th and 8th weeks. The osseointegration of the implants were compared by histomorphometry and resonance frequency analysis (RFA). Results: The Bone Implant Contact (BIC) values were significantly higher in the HBO group than in the control group at the 4th week. There was no difference in the BIC values between the groups at the 8th week. There was no significant difference in the RFA scores between the groups both at the 4th and 8th weeks after the operation. Conclusion: Histomorphometry findings suggest that HBO has positive effect on implant osseointegration in the early healing period in diabetic rabbits. However, implant stability is not affected by HBO treatment.Article Citation Count: 0Transoral endoscopic assisted reduction and internal fixation of mandibular condylar neck fractures with short condylar segment(Churchill Livingstone, 2024) Abdelazeem, Mohamed Hazem; Erdoğan, Özgür; Çakır, Merve; Ağız,Diş ve Çene Cerrahisi / Oral, Dental and Maxillofacial SurgeryThis study aimed to assess the reliability and safety of transoral endoscopic-assisted reduction internal fixation (TERIF) for treating short-segment condylar neck fractures (CNF), including hardware removal. Patients with displaced CNF and short condylar segments treated using TERIF were included in the study. Clinical evaluation covered dental occlusion, range of mouth opening, deviation during mouth opening, protrusion, laterotrusion, pain, and chewing. Radiological evaluation was used to assess fracture displacement, angulation, head dislocation, postoperative reduction, fixation stability, and bone healing. The same technique was used to treat 15 patients with 18 CNF and short condylar segments. Hardware removal was performed for nine fractures in eight patients after fracture healing using the same approach. All patients regained satisfactory, pain-free mouth opening with no deviation and complete bone healing. Computed tomographic images displayed adequate reduction and stable fixation during the follow-up period for all patients. No temporary or permanent facial nerve impairment occurred in any of the patients. TERIF is a reliable and safe treatment for CNF with short condylar segments, even in the presence of head dislocation, medial override, and malunited fractures; hardware can be safely removed after healing using the same approach.Article Citation Count: 1Implications of an Anatomical Variation of the Infraorbital Nerve in Orbital Floor Reconstruction(Lippincott Williams & Wilkins, 2022) Erdoğan, Özgür; Erdogan, Ozgur; Osman, Mohamed Fouad; Awad, Tarek Ahmed; Ağız,Diş ve Çene Cerrahisi / Oral, Dental and Maxillofacial SurgeryFractures involving the orbital floor such as blow-out fractures may cause damage to the infraorbital nerve (ION). The integrity and course of the nerve should be evaluated preoperatively in order to prevent from such nerve injuries. The anatomy of the ION can show variations in significant number of patients, which should be taken into account in treatment planning. In this report, the authors present a patient with an isolated fracture of the orbital floor, who had abnormal anatomy of his both IONs. Our treatment approach for this patient is presented along with relevant literature findings.Article Citation Count: 1Transoral Endoscopic-Assisted Reduction and Internal Fixation of Mandibular Condylar Fractures in Children(W B Saunders Co-elsevier inc, 2023) Erdoğan, Özgür; Aboelela, Salma; Erdogan, Ozgur; Ağız,Diş ve Çene Cerrahisi / Oral, Dental and Maxillofacial SurgeryPurpose: Extraoral approaches for open reduction and fixation of condylar fractures in children are associated with serious risks of complications, including facial nerve injury, facial scarring, parotid fistula, and auriculotemporal nerve injury. The purpose of this study was to retrospectively evaluate the outcomes of transoral endoscopic-assisted open reduction and internal fixation of condylar fractures and hardware removal in pediatric patients. Material and Methods: This study was designed as a retrospective case series. The study included pe-diatric patients admitted with condylar fractures that were indicated for treatment with open reduction and internal fixation. The patients were clinically and radiographically evaluated with regard to occlusion, mouth opening, lateral and protrusive movement of the mandible, pain, chewing and speech difficulties, and bone healing at the fracture site. Computed tomography images were used to assess the reduction of the fractured segment, the stability of fixation and progress of healing of the condylar fracture at follow-up visits. The same surgical treatment approach was applied to all patients. The data from the study were analyzed for a single group without any comparison to other groups. Results: The technique was used for the treatment of 14 condylar fractures in 12 patients between the ages of 3 to 11 years. A total of 28 transoral endoscopic-assisted approaches to the condylar region either for reduction and internal fixation or hardware removal were applied. The mean operating time was 53.1 (+/- 11.3) minutes for the fracture repair and 20 (+/- 2.6) minutes for hardware removal, respectively. The mean follow-up time of the patients was 17.8 (+/- 2.7) months (median: 18) months. All patients regained stable occlusion, satisfactory mandibular motion, stable fixation, and complete bone healing at the frac-ture site at the end of their follow-up period. There was no transient of permanent facial nerve or trigem-inal nerve injury in any of the patients. Conclusions: Endoscopically assisted transoral approach is a reliable technique for reduction and inter-nal fixation of condylar fracture and hardware removal in pediatric patients. The serious risks of extraoral approaches including facial nerve injury, facial scar, and parotid fistula can be eliminated by using this tech-nique. (c) 2023 American Association of Oral and Maxillofacial Surgeons J Oral Maxillofac Surg 81:566-574, 2023Article Citation Count: 1Comparison of the use of piezosurgery expander and conventional instruments on primary implant stability(Wolters Kluwer Medknow Publications, 2020) Erdoğan, Özgür; Erdogan, O.; Ağız,Diş ve Çene Cerrahisi / Oral, Dental and Maxillofacial SurgeryObjective: To compare the use of a piezosurgery expander and conventional chisel/osteotome on primary implant stability. Materials and Methods: Twenty fresh ribs were divided into two main groups; group P and group C. In group P, bone expansion was performed using piezosurgery. In group C, bone expansion was performed using conventional chisel osteotomy. In both groups, the implants were inserted into the ribs after bone expansion. After implant placement, primary stability values were evaluated from the bucco-lingual (B-L) and mesio-distal (M-D) sides of the implant. Results: The primary stability values on the B-L side of both implants in group P were significantly higher than in group C (P < 0.05). Conclusion: The use of piezo-expanders in the alveolar split technique has better effects on primary implant stability compared with the conventional technique.Article Citation Count: 5An In-vitro study on thermal changes during implant drilling with different irrigation volumes(Wolters Kluwer Medknow Publications, 2019) Erdoğan, Özgür; Sumer, M.; Kaya, O. A.; Keskiner, I.; Meral, D. G.; Erdogan, O.; Ağız,Diş ve Çene Cerrahisi / Oral, Dental and Maxillofacial SurgeryObjective: Irrigation with saline is one of the essential methods for reducing the heat generated during dental implant osteotomy. High irrigation volume impairs visibility of the surgical field, thus complicates the surgery. In this study, we aimed to determine the optimal irrigation volume for heat reduction during dental implant drilling. Materials and Methods: Thirty-two implant osteotomies were prepared on four fresh cow ribs. Heat generated during the final implant drilling was measured both with infrared thermography and thermocouple method. Initial and maximum temperatures were measured at four different irrigation volumes; 32, 44, 56, and 68 ml/min. Results: Both measurement methods showed that the amount of temperature rise is associated with the irrigation volume during implant drilling. There is no further decrease in temperature rise above irrigation volume of 56 ml/min. Conclusion: Saline irrigation with 56 ml/min provides sufficient heat reduction during dental implant drilling and higher irrigation volumes are not necessary.Article Citation Count: 1Endoscopically Assisted Transoral Gap Arthroplasty of the Temporomandibular joint Ankylosis in a Pediatric Patient(Lippincott Williams & Wilkins, 2018) Erdoğan, Özgür; Erdogan, Ozgur; Awad, Tarek Ahmed; Ağız,Diş ve Çene Cerrahisi / Oral, Dental and Maxillofacial SurgerySurgical management of temporomandibular joint (TMJ) ankylosis in children is often challenging and may result in various complications such as facial nerve injury and visible scar. In this clinical report, the authors present minimally invasive management of a 9-year-old boy with bilateral post-traumatic TMJ ankylosis. The ankylotic TMJs were addressed and gap arthoplasties were performed by endoscopically assisted transoral approach. The risk of facial nerve injury is minimized and facial scar was prevented by avoiding extraoral incision. Mandibular movements in 3 directions were satisfactory at 3rd postoperative month.Article Citation Count: 0Promax artefakt azaltma algoritmasının titanyum ve zirkonyum implantların oluşturduğu artefaktlar üzerine etkisi(2020) Erdoğan, Özgür; Buyuk, Cansu; Tamer Lütfi ERDEM; Belde ARSAN; Ağız,Diş ve Çene Cerrahisi / Oral, Dental and Maxillofacial Surgery; Ağız,Diş ve Çene Radyolojisi / Oral, Dental and Maxillofacial RadiologyAmaç: Artefaktlar görüntü kalitesini düşürürler.
