Objectives: To review and assess the efficiency of different post extraction socket preservation techniques.

Material and methods: An electronic literature search was performed on the MEDLINE and Embase databases. The review included human studies published between from January 1st, 2007 to January 1st, 2018, in English. Outcome measures included dimensional changes and/or histological evaluation of alveolar bone.

Results: Twenty-six full text articles were reviewed, 16 of which met the inclusion criteria and were selected for the study. Autogenous tooth graft prevented vertical resorption the most: -0.28 (SD 0.13) mm, observation period (OP): 4 months, while the least effective approach was beta tri-calcium phosphate (β-TCP): -1.72 (SD 0.56) mm, OP: 4 months. Estimating horizontal resorption, the most effective technique was biphasic calcium sulphate (BCS) with β-TCP and hydroxyapatite (HA) - BCS + TCP + HA: 0.03 (SD 2.32) mm, OP: 4 months, while β-TCP was the least efficient: -1.45 (SD 0.4) mm, OP: 4 months. Evaluating residual graft particles (RG) and newly formed bone (NFB) ratio the best results were achieved with demineralized freeze-dried bone allograft: RG: 8.88%, NFB: 38.42%, OP: 5 months, whereas magnesium-enriched hydroxyapatite was least effective: RG: 40.82%, NFB: 31.85%, OP: 4 months.

Conclusions: This review revealed that even though there are numerous types of biomaterials for socket preservation none of them can completely stop alveolar bone loss after tooth extraction. Furthermore, lack of information about qualitative evaluation of bone was noticed indicating that further studies regarding this topic are needed.

目的:评价不同的拔牙后牙槽保存技术的有效性。材料和方法:在MEDLINE和Embase数据库中进行电子文献检索。该综述包括2007年1月1日至2018年1月1日期间发表的英文人类研究。结果测量包括牙槽骨的尺寸变化和/或组织学评价。结果:共审查了26篇全文文章,其中16篇符合纳入标准,入选本研究。自体植牙对垂直吸收的抑制效果最好:-0.28 (SD 0.13) mm,观察期(OP) 4个月;对-磷酸三钙(β-TCP)的抑制效果最差:-1.72 (SD 0.56) mm, OP 4个月。估计水平吸收,最有效的技术是双相硫酸钙(BCS) + β-TCP和羟基磷灰石(HA) - BCS + TCP + HA: 0.03 (SD 2.32) mm, OP: 4个月,而β-TCP效率最低:-1.45 (SD 0.4) mm, OP: 4个月。评价残骨颗粒(RG)和新生骨(NFB)比例,脱矿冻干同种异体骨移植效果最好,RG: 8.88%, NFB: 38.42%, OP: 5个月;富镁羟基磷灰石效果最差,RG: 40.82%, NFB: 31.85%, OP: 4个月。结论:本综述显示,尽管有许多类型的生物材料用于牙槽保存,但没有一种可以完全阻止拔牙后牙槽骨的丢失。此外,人们注意到缺乏关于骨定性评价的信息,这表明需要进一步研究这一主题。

Objectives: The aim of the present prospective study was to evaluate, by means of intraoral periapical radiographs and cone-beam computed tomography, hard tissue changes after ridge augmentation procedures in posterior extraction sockets with severe wall defects.

Material and methods: Twenty patients, with a non-restorable premolar/molar tooth and severe wall defect, were enrolled in the present study, and underwent single-tooth extraction. Extraction sites were grafted with porcine-derived bone covered by porcine-derived collagen membrane. Intraoral periapical radiographs and cone-beam computed tomography scans, obtained at enrolment, and 6 months after ridge augmentation procedures were analysed and compared.

Results: In the intraoral periapical radiographs, mean vertical bone gains detected at the distal, central and mesial aspects of the extraction sockets were 3.5 (SD 1.1) mm, 8.2 (SD 2.1) mm, and 3.9 (SD 1.7) mm, respectively. In the cone-beam computed tomography scans, the mean vertical bone gains detected at the more vestibular and more palatal aspects were 4.4 (SD 1.9) mm, and 3.3 (SD 2.8) mm, respectively. The mean horizontal bone gain was 3.5 (SD 1.6) mm. In all examined defects, mean vertical and horizontal bone levels showed a statistically significant increase (P < 0.05) at 6 months after extraction.

Conclusions: Within the limits of this study, the results suggest that porcine-derived bone graft covered by a collagen membrane can support significant vertical and horizontal bone gain at posterior post-extraction sockets with severe wall defects.

目的:本前瞻性研究的目的是通过口腔内根尖周x线片和锥形束计算机断层扫描来评估后牙槽嵴增强手术后严重牙槽壁缺损的硬组织变化。材料与方法:选取20例前磨牙/磨牙不可修复且牙壁严重缺损的患者,行单牙拔除术。提取部位用猪源性骨移植,并用猪源性胶原膜覆盖。在入组时和隆胸术后6个月获得的口腔内根尖周x线片和锥形束计算机断层扫描进行了分析和比较。结果:在口腔内根尖周x线片上,拔牙槽远端、中端和中端平均垂直骨增益分别为3.5 (SD 1.1) mm、8.2 (SD 2.1) mm和3.9 (SD 1.7) mm。在锥形束ct扫描中,在前庭和腭侧检测到的平均垂直骨增益分别为4.4 (SD 1.9) mm和3.3 (SD 2.8) mm。平均水平骨长高为3.5 (SD 1.6) mm。在所有检查的缺损中,拔牙后6个月,平均垂直和水平骨水平均有统计学意义(P < 0.05)升高。结论:在本研究范围内,结果表明,胶原膜覆盖的猪源性骨移植物可以在具有严重骨壁缺损的后牙臼处支持显著的垂直和水平骨增加。

Background: Digital revolution is here and becoming more and more influential in our daily lives by transforming several things such as our habits, interactions with other people and the practice of dentistry. In implant dentistry, the newer methods by using cone-beam computed tomography and computer-aided design and computer-aided manufacturing recently offer more predictable and aesthetics outcomes in a shorter period of treatment time when compared to the traditional prosthetic procedures.

Methods: A 66 year-old male patient with an edentulous mandible and several failing maxillary teeth presented to our clinic. After cone-beam computed-tomography scans and virtual implant placement by using three-dimensional software, a stereolithographic surgical guide was fabricated. The patient received two mandibular implants without any flap elevation by means of a computer-aided design and computer-aided manufacturing surgical guide and a maxillary complete denture in a day.

Results: The surgical and restorative procedures were performed without any issues. The patient was followed-up for three years and no major complications with the implants and prostheses were observed.

Conclusions: The technique illustrated in this report may be successfully used to restore edentulous arches in a day if it is executed by trained restorative dentists and if patient selection is appropriate.

Objectives: The purpose of this study was to determine the effects of strontium ranelate on ligature-induced periodontitis in rats and assess the putative involvement of heme oxygenase-1 (HO-1) pathway in these effects.

Material and methods: Male Wistar rats underwent nylon ligature placement around maxillary molars and were treated (v.o.) with strontium ranelate (20 or 100 mg/kg) for 7 days. After that, rats were euthanized and histomorphometric/histopathological analyses and RT-PCR for HO-1 expression were performed.

Results: Strontium ranelate (20 or 100 mg/kg) prevented bone resorption by 28% and 38%, respectively. Strontium ranelate treatment (100 mg/kg) up-regulated (P < 0.05) heme oxygenase-1 mRNA levels in the gingival tissues in comparison to control groups.

Conclusions: Strontium ranelate prevented periodontal bone loss in experimental periodontitis in rats while heme oxygenase-1 mRNA levels increased after treatment.

目的:本研究的目的是确定雷奈酸锶对大鼠结扎性牙周炎的作用,并评估血红素加氧酶-1 (HO-1)途径在这些作用中的可能参与。材料与方法:雄性Wistar大鼠上颌磨牙周围放置尼龙结扎,用雷奈酸锶(20或100 mg/kg)治疗7 d。然后对大鼠实施安乐死,进行组织形态学/组织病理学分析和HO-1表达的RT-PCR检测。结果:雷奈酸锶(20或100 mg/kg)对骨吸收的抑制作用分别为28%和38%。与对照组相比,雷奈酸锶处理(100 mg/kg)可上调牙龈组织血红素加氧酶-1 mRNA水平(P < 0.05)。结论:雷奈酸锶可预防实验性牙周炎大鼠牙周骨丢失,治疗后血红素加氧酶-1 mRNA水平升高。

Objectives: The purpose of the present study was to evaluate the effects of kinesio taping on pain and swelling after surgically assisted rapid palatal expansion.

Material and methods: A total of 21 (12 male and 9 female) patients with transverse maxillary deficiency were enrolled in the study. Kinesio taping (KT) was applied unilaterally in each patient, whereby sides of the face with KT application were included into the (a) KT group and the other sides were included into the (b) non-KT group. Changes in facial volume were evaluated on digital images using the 3dMD Face System. Pain scores were assessed at postoperative days 1, 2, 3, 4, 5, 6, and 7 using the visual analog scale (VAS). Two-way repeated measures analysis of variance and Mann Whitney U test were used for statistical analyses.

Results: Swelling was significantly lower in the KT group compared to the non-KT group from T0 to T1 (36.42 [SD 19.71] mm3 vs. 183.84 [SD 49.33] mm3) and was significantly greater in the non-KT group compared to the KT group from T0 to T2 (70.88 [SD 15.73] mm3 vs. 21.46 [SD 13.39] mm3) (P < 0.001 for both). The VAS scores were significantly lower in the KT group compared to the non-KT group at all time points (P < 0.05).

Conclusions: The application of kinesio taping after maxillofacial surgery reduced the pain and swelling in the postoperative period. Kinesio taping can be used as an alternative to other methods that are used for the reduction of postoperative complaints.

目的:本研究的目的是评估运动贴贴对手术辅助快速腭扩张后疼痛和肿胀的影响。材料与方法:21例上颌横向缺损患者(男12例,女9例)入组研究。每位患者单侧应用运动内肌贴敷(KT),其中应用KT的面部两侧被纳入(a) KT组,其他两侧被纳入(b)非KT组。使用3dMD面部系统在数字图像上评估面部体积的变化。术后第1、2、3、4、5、6、7天采用视觉模拟评分(VAS)评估疼痛评分。统计分析采用双向重复测量方差分析和Mann Whitney U检验。结果:T0至T1期间,KT组肿胀明显低于非KT组(36.42 [SD 19.71] mm3 vs. 183.84 [SD 49.33] mm3), T0至T2期间,非KT组肿胀明显高于KT组(70.88 [SD 15.73] mm3 vs. 21.46 [SD 13.39] mm3)(两者P < 0.001)。KT组VAS评分在各时间点均明显低于非KT组(P < 0.05)。结论:颌面部手术后应用运动贴可减轻术后疼痛和肿胀。肌内效贴敷可作为其他方法的替代方法,用于减少术后不适。

Objectives: The aim of this retrospective study is to investigate the prevalence, three-dimensional positions and supplementary findings of the presence of a mesiodens by using cone-beam computed tomography.

Material and methods: A total of 5000 cone-beam computed tomography (CBCT) scans, taken between December 2015 and March 2018, from the archive of Istanbul University Faculty of Dentistry Department of Oral and Maxillofacial Radiology, were screened. In sum, 2003 CBCT scans fulfilled inclusion criteria in this study. In addition to number of mesiodens, age and sex of the patients, shape, eruption status and direction, findings of the presence of a mesiodens were also recorded. Mesiodentes were classified according to their positions in frontal, sagittal and axial planes.

Results: In this study, the prevalence of mesiodens was found 5.04% and to be more frequent in males than in females with the ratio of 1.9 : 1. One hundred thirty maxillary mesiodentes were detected in 101 cases out of 2003 CBCT scans. In 77 cases (76.2%), single mesiodens; in 19 cases (18.8%), two mesiodentes; and in 5 cases (4.9%), three mesiodentes were found. According to our classification, mesiodentes were mostly found in between midlines of central incisors (both the crown and root of mesiodens) in frontal plane, impacted and in contact with central incisors in sagittal plane, anterior to nasopalatine canal and in contact with nasopalatine canal in axial plane.

Conclusions: Cone-beam computed tomography provides more detailed information about position, neighbouring anatomic structures, and local findings of the presence of mesiodentes in multiplanar sections.

Background: This case report shows an affected postmenopausal patient with medicaments related osteonecrosis of the jaw injury associated with increased use of bisphosphonates and Prolia® (denosumab) for the treatment of osteoporosis. The mechanism of action of the receptor activates the denosumab of the nuclear-kB factor binding and makes nuclear-kB Factor, reducing bone volume and reabsorption in the trabecular and cortical bones and, consequently, decreasing an incidence of fractures and maintaining a bone formation. The bone physiology regulated by the hormones calcitonin, parathormone and vitamin D also undergoes interference.

Methods: The injury was located around a dental implant in region #24 and #25 and the patient complained of pain, bleeding, oedema, and halitosis for more than two months, that the dental implant had been installed five years before. According to the clinical findings, the patient presented the exposed and necrotic bone in the region of #24 and #25 and with the radiographs found, it was observed as extensive bone destruction adjacent to the dental implant.

Results: Patient was referred to the maxillofacial surgeon that performed the removal of bone sequestration and dental implant in the region affected. After that, the patient has been accompanied for a year.

Conclusions: Patients taking medications for osteoporosis or cancer need to receive special attention from the dentist. Invasive procedures on the jaw bone of patients taking these medications may cause osteonecrosis of the jaw. When diagnosed, osteonecrosis of the jaw should be treated surgically in conjunction with antibiotic therapy and patients should be monitored.

背景:本病例报告显示了一个绝经后患者与药物相关的颌骨坏死损伤相关的使用增加双磷酸盐和Prolia®(denosumab)治疗骨质疏松症。受体的作用机制激活核- kb因子结合的去单抗,使核- kb因子产生,减少骨小梁和皮质骨的骨体积和重吸收,从而减少骨折的发生率,维持骨形成。由降钙素、甲状旁激素和维生素D调节的骨生理也受到干扰。方法:患者位于种植体的24区和25区,疼痛、出血、水肿、口臭超过2个月,患者为5年前安装的种植体。根据临床表现,患者在#24和#25区域出现骨暴露和坏死,x线片显示种植牙附近有广泛的骨破坏。结果:患者转诊至颌面外科,在患区进行骨隔离和种植体去除。在那之后,病人已经被陪伴了一年。结论:服用骨质疏松或癌症药物的患者需要得到牙医的特别关注。对服用这些药物的患者的颌骨进行侵入性手术可能会导致颌骨骨坏死。确诊后,颌骨骨坏死应手术治疗并结合抗生素治疗,并对患者进行监测。

Objectives: To determine the approximate location, shape and dimensions of the mental foramen in African subjects using panoramic radiographs.

Material and methods: This study analysed 320 orthopantomograms of subjects from two centres. The analysis was done using the radiographic software tools (SIDEXIS, Bensheim, Germany) which allowed for determination of the position, shape and dimensions of the foramen. Furthermore, the right and left mental foramina were compared to ascertain both shape and positional symmetry.

Results: Most of the foramina analysed were horizontally positioned between the mandibular first and second premolars (65.9%) and vertically positioned greater than 2 mm below the apex of the second mandibular premolars. The average vertical dimension and horizontal dimension of the foramen is 2.87 (SD 1) mm and 3.56 (SD 1.23) mm respectively with 55.2% of the foramen analysed being ovoid in shape. Asymmetrical mental foramina were seen in 164 subjects (51.3%) while 156 subjects had symmetrical mental foramina (48.7%).

Conclusions: The mental foramen is most commonly located between the mandibular premolars, greater than 2 mm below the apex of the second mandibular premolars. They are usually ovoid in shape with an almost equal distribution of asymmetry and symmetry.

目的:利用全景x线片确定非洲受试者精神孔的大致位置、形状和尺寸。材料和方法:本研究分析了来自两个中心的320名受试者的正位断层摄影。分析使用放射照相软件工具(SIDEXIS, Bensheim, Germany),可以确定孔的位置、形状和尺寸。此外,还比较了左右脑孔的形状和位置对称性。结果:65.9%的孔位于下颌第一、第二前磨牙之间,65.9%的孔位于下颌第二前磨牙尖下大于2mm的孔。孔的平均垂直尺寸为2.87 (sd1) mm,水平尺寸为3.56 (sd1.23) mm,其中卵圆形占55.2%。心理孔不对称者164例(51.3%),对称者156例(48.7%)。结论:颏孔最常位于下颌前磨牙之间,下颌第二前磨牙尖下大于2mm。它们通常呈卵形,对称和不对称的分布几乎相等。

Objectives: The review aims to study dental implant placement purposefulness for patients who have been treated or are on treatment with bisphosphonate medication.

Material and methods: Structured search strategy was applied on electronic databases: MEDLINE, PubMed, PubMed Central and ResearchGate. Scientific publications in English between 2006 and 2017 were identified in accordance with inclusion, exclusion criteria. Publication screening, data extraction, and quality assessment were performed. Outcome measures included implant failure or implant-related osteonecrosis of the jaw.

Results: In total, 32 literature sources were reviewed, and 9 of the most relevant articles that are suitable to the criteria were selected. Heterogeneity between the studies was found and no meta-analysis could be done. Five studies analysed intraoral bisphosphonate medication in relation with implant placement, three studies investigated intravenous bisphosphonate medication in relation with implant placement and one study evaluated both types of medication given in relation with implant placement. Patients with intraoral therapy appeared to have a better implant survival (5 implants failed out of 423) rate at 98.8% vs. patients treated intravenously (6 implants failed out of 68) at 91%; the control group compared with intraoral bisphosphonate group appeared with 97% success implant survival rate (27 implants failed out of 842), showing no significant difference in terms of success in implant placement.

Conclusions: Patients treated with intravenous bisphosphonates seemed to have a higher chance of developing implant-related osteonecrosis of the jaw. The intraorally treated patient group appeared to have more successful results. Implant placement in patients treated intraorally could be considered safe with precautions.

目的:本综述旨在研究已接受或正在接受双膦酸盐药物治疗的患者种植体放置的目的性。材料与方法:在MEDLINE、PubMed、PubMed Central和ResearchGate等电子数据库中采用结构化检索策略。根据纳入、排除标准对2006年至2017年的英文科学出版物进行筛选。进行出版物筛选、数据提取和质量评估。结果测量包括种植体失败或种植体相关的颌骨骨坏死。结果:共查阅文献32篇,筛选出符合标准的相关文献9篇。研究之间存在异质性,无法进行meta分析。五项研究分析了口服双膦酸盐药物与种植体放置的关系,三项研究调查了静脉注射双膦酸盐药物与种植体放置的关系,一项研究评估了两种类型的药物与种植体放置的关系。口腔内治疗的患者种植体存活率(423例中有5例种植体失败)为98.8%,而静脉内治疗的患者(68例中有6例种植体失败)为91%;对照组与口腔内双膦酸盐组相比,种植体成活率为97%(842颗种植体中有27颗失败),种植体放置成功率无显著差异。结论:静脉注射双膦酸盐治疗的患者似乎有更高的机会发生种植体相关性颌骨骨坏死。口服治疗组似乎有更成功的结果。经口内治疗的患者种植体放置可以被认为是安全的,但要注意预防。

Objectives: The purpose of this in vitro study was to evaluate effect of implant location on initial retention values of palateless complete overdentures retained by four o-rings at different inter-implant distances.

Material and methods: Two standard acrylic models representing completely edentulous maxillary arches were used. Four single piece ball type implants were placed in each model. Models were divided into two groups according to the distance between anterior and posterior implants. Two canine implants with 32 mm inter-implant distance were placed in both models. In one model (G1), two posterior implants were placed in second premolar region away from canine implants by 14 mm on both sides, while in the other model (G2), the two posterior implants were placed in first molar region away from canine implants by 22 mm on both sides. Eighteen palateless complete overdentures were constructed for each model. Overdentures were retained by four o-rings. Initial axial (central), and para-axial (anterior, posterior, and lateral) retention values of overdentures were estimated and compared using a universal testing machine.

Results: Independent t-test revealed that implant location has a significant role in palateless complete overdenture retention with a level of significance set at P < 0.05.

Conclusions: For in vitro simulated palateless implant overdentures retained by four o-rings, increasing the inter-implant distance between anterior and posterior implants is favourable for a more retentive prosthesis.

目的:本体外研究的目的是评估种植体位置对四个o型环固定的无腭全覆盖义齿在不同种植间距离上的初始固位值的影响。材料和方法:使用两个标准丙烯酸模型代表完全无牙颌弓。每个模型放置4个单片球型植入物。根据种植体前后距离将模型分为两组。两种模型均置入2枚犬种植体,种植体间距为32 mm。在一个模型(G1)中,两个后牙种植体放置在距离犬齿种植体两侧14 mm的第二前磨牙区域,在另一个模型(G2)中,两个后牙种植体放置在距离犬齿种植体两侧22 mm的第一磨牙区域。每个模型制作18个无腭全口覆盖义齿。覆盖义齿由4个o形环固定。使用通用试验机估计和比较覆盖义齿的初始轴向(中央)和轴向旁(前、后、外侧)固位值。结果:独立t检验显示种植体位置对无腭全覆盖义齿固位有显著影响,P < 0.05。结论:对于四o型环固位的体外模拟无腭覆盖义齿,增加前、后种植体之间的种植间距有利于获得更好的固位效果。
