    (Medicina Oral S L, 2019) Menziletoglu, Dilek; Tassoker, Melek; Kubilay-Isik, Bozkurt; Esen, Alparslan
    Background: Our purpose was to investigate the relationship between the angulation of mandibular third molars and the thickness of the lingual bone, which can affect the risk of lingual nerve damage during lower third molars surgical extraction. Material and Methods: This study consisted of 104 patients (42 males and 62 females). aged between 18-42 years (24.67 +/- 6.11 years). Cone Beam Computed Tomography (CBCT) images were taken for preoperative assessment. The teeth were divided into four groups according to their positions: mesioangular, distoangular, vertical and horizontal. Lingual bone thickness around impacted teeth were measured at three points: cementoenamel junction (CEJ) of the mandibular second molar, mid-root of the impacted third molar, and apex of the impacted third molar root. Two predisposing factors of lingual nerve damage were recorded: lingual bone perforated by the impacted tooth and lingual bone thinner than 1 mm. Additionally, buccolingual angulations of the teeth in each group were measured. Impacted mandibular third molars were removed in usual way. One week after surgery, the patients were evaluated regarding lingual nerve paresthesia. Results: None of the 104 patients experienced paresthesia. including the ones who had teeth with close proximity with lingual nerve. The mean thickness of bone was 1.21 +/- 0.63 mm at CEJ of the second molar; 1.25 +/- 1.02 mm at the mid-root; and 1.06 +/- 1.31 mm at the apex. Horizontally impacted teeth had thinner lingual bone at mid-root level (p=0.016). Buccolingual angulated teeth were more often associated with perforated lingual bone (p=0.002). Buccolingual and mesial/distal angulation had negative correlation with lingual bone thickness (p<0.05). Conclusions: As the buccolingual and mesiodistal angulations increase, lingual bone thickness decreases. Horizontally impacted teeth seemed to compromise the integrity of the lingual bone more than impacted teeth in other positions. During the surgery, thin or perforated lingual bone may result in displacement of the impacted tooth lingually.

    (Galenos Publ House, 2022) Esen, Cagri; Esen, Alparslan; Guler, Arif Yigit; Menziletoglu, Dilek; Soganci, Ahmet Ertan
    Objective: The aim of this retrospective study was to evaluate the changes in alveolar bone height (ABH) and buccal bone thickness (BBT) of the maxillary teeth after surgically assisted rapid maxillary expansion (SARME) using cone-beam computed tomography (CBCT). Materials and Methods: A total of 9 patients with preoperative and postoperative CBCT records were included in this study. All patients underwent SARME and all of them received a modified acrylic bonded appliance as a maxillary expander. CBCT images were taken before SARME (T1) and after a consolidation period of 3 to 4 months (T2). ABH was determined by measuring the distance from the cemento-enamel junction to the alveolar crest on CBCT images. To evaluate BBT, two different points were identified along the root surface. Results: Alveolar bone loss (ABL) detected between T1 and T2 ABH measurements was statistically significant at all sites of each tooth. There was a statistically significant decrease in BBT at all measured points of each tooth between the T1 and T2 measurements. Conclusion: SARME with modified acrylic-bonded appliances causes ABL and a decrease in BBT, which increases the risk of tooth loss and gingival recession.

    Biomechanical evaluation of different fixation systems after Le Fort I osteotomy in polyurethane models of unilateral clefts
    (Churchill Livingstone, 2016) Esen, Alparslan; Isik, Kubilay; Saglam, Haci; Ozdemir, Yusuf Bugra; Dolanmaz, Dogan
    We 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.

    Evaluation of strain values of critical anatomic regions for two different pterygomaxillary approaches in Le Fort I osteotomy: An experimental study
    (Medicina Oral S L, 2017) Ozdemir, Yusuf-Bugra; Dolanmaz, Dogan; Esen, Alparslan; Terzioglu, Hakan; Saglam, Haci
    Background: 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. Material and Methods: The prepared skull models were randomly divided into 2 groups of 7. In the first group (A), the pterygomaxillary area was left intact. In the second group (B), pterygomaxillary separation was performed with a fine bur. The stresses were measured by using strain gauges. These strain gauges were attached to 6 different anatomical sites. The skull models were mounted on a servo-hydraulic testing unit. Each model was then subjected to a continuous linear tension until a plastic deformation was seen. Results: The statistical analyses showed that there were no significant differences (p>.05) between the 2 groups regarding the strain values. Moreover, no statistical differences (p>.05) were found between the two groups in terms of maximum applied forces. Conclusions: Considering the clinical conditions, the present study shows that when Le Fort I osteotomy performed without pterygomaxillary separation, there is no significant stress on the skull base during the downfracture. Moreover, it is considered that there is no need for an excessive force applied to perform downfracture in Le Fort osteotomies without pterygomaxillary separation.

    Evaluation of stress distribution in critical anatomic regions following the Le Fort I osteotomy by three-dimensional finite element analysis
    (Churchill Livingstone, 2019) Esen, Alparslan; Dolanmaz, Elvan; Dolanmaz, Dogan
    In this study, we aimed to measure the stresses both on the pterygoid plates and the cranial base during the down-fracture and at the time of pterygomaxillary osteotomy by using the finite element analysis method to have an idea about the possible causes of complications. Three different surgical approaches were applied to the obtained models. In the Model 1, Le Fort I cuts without pterygomaxillary separation was applied. In the Model 2, same standard Le Fort I cuts were applied with pterygomaxillary separation. Then both models were subjected to a force of 150 N over the anterior spina nasalis to simulate down-fracture. In the third model, same standard Le Fort I cuts were applied. Following this procedure, a force of 50 N was applied with a sharp osteotome to the pterygomaxillary junction to simulate osteotomy. According to the results of this experimental study, the cranial base stress values decreased during the down-fracture in the Model 2. Moreover, it was found that the force transmitted to the base of the skull is less when the height of the pterygomaxillary osteotome is limited to 1 cm as we applied in Model 3.

    Histological evaluation of effectiveness of platelet-rich fibrin on healing of sinus membrane perforations: A preclinical animal study
    (Churchill Livingstone, 2017) Aricioglu, Ceyhun; Dolanmaz, Dogan; Esen, Alparslan; Isik, Kubilay; Avunduk, Mustafa Cihat
    The 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.

    How effective is a thick plate on stabilisation in 10 mm mandibular advancement?
    (Churchill Livingstone, 2022) Esen, Alparslan; Menziletoglu, Dilek; Erdur, Emire Aybuke; Akkulah, Sebnem
    We compared the stability and stress analysis of four different fixation methods after sagittal split ramus osteotomy (SSRO) in mandibular models. In the first model (1P1B) we adapted a four-hole, 2.0 mm standard miniplate on the osteotomy line with one bicortical screw at the top. In the second (2P) we placed two four-hole 2.0 mm standard miniplates above and below the osteotomy line. In the third (3B), we applied three inverted L-shaped bicortical screws, and in the last (1RP1B) we used a four-hole miniplate with increased thickness on the osteotomy line with one bicortical screw at the top. A static vertical load of 200 Newtons (N) was then applied to each model from the occlusal of the first molar. The maximum and minimum principal stresses on the bone were observed more in the proximal segment close to the osteotomy line in all groups. Maximum von Mises stresses were 2705.21 Megapascals (MPa), 1633.56 MPa, 1121.4 MPa, and 1734.44 MPa for the 1P1B, 2P, 3B, and 1RP1B groups, respectively. Displacement values were 1.92 mm, 1.15 mm, 0.79 mm, and 1.42 mm for the 1P1B, 2P, 3B, and 1RP1B groups, respectively. The reinforced plate contributed to the stabilisation, but it was not as effective as three bicortical screws and a double plate. (C) 2021 The British Association of Oral and Maxillofacial Surgeons.

    Management of central giant cell granuloma of the jaws with intralesional steroid injection and review of the literature
    (Springer Heidelberg, 2016) Dolanmaz, Dogan; Esen, Alparslan; Mihmanli, Ahmet; Isik, Kubilay
    We report the results of the intralesional steroid injections for the management of central giant cell granuloma (CGCG) of the jaws. Seven CGCGs were treated with intralesional injection of corticosteroids. To accomplish this, 3.5 mL of triamcinolone and 3.5 mL of 0.5 % marcaine with 1/200,000 epinephrine (total 7 mL) were mixed. An adequate amount of steroid was injected into different areas of the lesion. This procedure was repeated on a weekly basis for 6 weeks. Clinical and radiological examination showed complete resolution and ossification of the lesions in four patients. Partial recovery was achieved in two patients. One patient did not respond to the treatment and underwent surgical curettage. We suggest that intralesional steroid injection is safe and effective for the treatment of CGCG, especially in non-aggressive lesions.

    Management of Large Oroantral Fistulas Caused by Medication-Related Osteonecrosis with the Combined Sequestrectomy, Buccal Fat Pad Flap and Platelet-Rich Fibrin
    (Springer India, 2021) Esen, Alparslan; Akkulah, Sebnem
    Purpose The aim of this retrospective study was to describe the efficacy of management of bisphosphonate-related maxillary osteonecrosis, which had resulted in an oroantral fistula formation, by performing sequestrectomy, platelet-rich fibrin (PRF) and buccal fat pad (BFP) flap. Patient and Methods A total of 7 patients diagnosed with stage III maxillary medication-related osteonecrosis according to guidelines of the American Association of Oral and Maxillofacial Surgeons. All patients complained of persistent pain, swelling and purulent drainage with sinusitis. In order to keep the infection under control, the patients first received an antibiotic combination for 2 weeks. Then, sequestrectomy and bone debridement were performed under general anesthesia. After that, an antrectomy was performed via endoscopic sinus surgery in some cases. And the fistula was closed with BFP after or before the PRF application to the region depending on the size of the fistula. Results The fistula was successfully closed. After a mean follow-up of 16 months, no symptoms were seen in the patients. Conclusions The patients were successfully managed with a combined treatment consisted of sequestrectomy, PRF and BFP. We suggest that large defects arose from medication-related osteonecrosis of the jaw can be managed with such a combined approach in order to lessen the recurrence risk.

    A prospective split-mouth clinical study: comparison of piezosurgery and conventional rotary instruments in impacted third molar surgery
    (Springer Heidelberg, 2020) Menziletoglu, Dilek; Basturk, Funda; Isik, Bozkurt Kubilay; Esen, Alparslan
    Purpose Our purpose was to compare the effects of piezosurgery and conventional rotary instruments on postoperative pain, swelling, trismus, and patients' comfort after mandibular third molar surgery. Methods Thirty patients (27 women and 3 men) with bilateral impacted mandibular third molars were included in this split-mouth clinical study. Sixty impacted third molars were divided into a control group (n = 30), in which the osteotomies were performed using a conventional rotary handpiece technique and an experimental group (n = 30), in which the osteotomies were done by piezosurgery technique. Duration of the procedure was recorded. Postoperative pain was assessed using a visual analogue scale (VAS). All the patients were given a form containing verbal rating scale for evaluating the swelling. Trismus was evaluated using a caliper at maximum mouth opening (cm). In postoperative seventh day, patients were asked to fill a global quality of life (QoL) scale as well. Results There was no significant difference in postoperative pain, trismus, and swelling between control and experimental groups (p > 0.05). However, time of the procedure increased in control group (p < 0.05). Conclusion Piezosurgery is a safe way for performing the osteotomies during third molar surgery. However, regarding the postoperative morbidity, it does not have an advantage over conventional rotary instruments. Piezosurgery took longer to complete the osteotomy than the rotary handpiece technique.

    Spontaneous bone regeneration in resected non-continuous mandible due to medication-related osteonecrosis of the jaw
    (Korean Acad Oral & Maxillofacial Surgery, 2021) Esen, Alparslan; Gurses, Gokhan; Akkulah, Sebnem
    Few cases of spontaneous bone regeneration after extensive resection of the jaw bone have been reported, but it is more common in young adults or children. In this case, we report spontaneous bone healing in a 73-year-old female patient. On radiological examination, necrotic regions were seen in the right mandible. She was diagnosed with medication-related osteonecrosis of the jaw due to previous bisphosphonate use. After segmental resection, stabilization achieved using a reconstruction plate. The periosieum was preserved during the procedure. Twelve months later. panoramic radiography was taken and hone formation was seen both horizontally and vertically around the plate. If the periosteum is preserved and stabilization is achieved after resection in benign lesions, the bone may regenerate spontaneously regardless of age. Therefore, instead of simultaneous autogenous bone application, such patients may be followed to determine whether spontaneous bone healing will occur. This should improve patient comfort and reduce surgical cost.
