Objectives: To present the survey questionnaire used for the medical assessment of patients requiring alveolar ridge reconstruction as well as the study of concomitant pathologies and their influence on the healing process. Material and methods: The study involved 173 patients aged between 18 and 69 years. All patients have been assessed according to the survey questionnaire developed to determine the patient’s general condition, life anamnesis, and medical history. Results: Out of the total of 173 patients, 72 (41.6%) had no concomitant pathologies, 8 patients (4.6%) had concomitant pathologies that did not interfere with the operation, 40 (23.1%) had pathologies that might affect the outcome of alveolar ridge reconstruction but still were admitted to surgery, and 53 patients (30.6%) had pathologies that could affect the outcome of the reconstruction procedure and were not admitted to bone grafting. Conclusions: Assessment of patients with alveolar ridge defects during preparation and planning of preimplantation bone reconstruction identified a number of concomitant pathologies, more or less noticed by the patient, which may remain unclear due to superficial study of the patient’s condition that is able to influence the surgical treatment outcome. These issues can be both intraoperative and postoperative and lead to failure of surgical treatment and further reoperation.

Abstract Objectives The aim of this study was to assess whether alveolar ridge preservation (ARP) can reduce the need of ridge augmentation at posterior tooth sites. Material and methods This study enrolled patients who received dental implants at posterior tooth sites during 2013–2019. Demographic data and dental treatment histories were collected. Based on healing patterns after tooth extraction, patients were divided into ARP and spontaneous healing (SH) groups. Three surgical treatment plans were devised according to the alveolar bone volume on cone-beam computed tomography (CBCT). The three treatment plans were to perform implant alone, simultaneous guided bone regeneration (GBR) and implantation, and staged GBR before implantation. Statistical analyses were performed to determine relationships. Results There were 92 implant records in the ARP group and 249 implant records in the SH group. A significant intergroup difference was observed regarding the frequency distribution of the treatment modality of staged GBR before implant (χ2 = 15.07, p = 0.0005). Based on the implant alone treatment modality and simple logistic regression, the SH pattern was related to staged GBR before implant (SH vs. ARP: crude odds ratio (OR) = 4.65, 95% confidence interval (CI) = 2.15–11.61, p = 0.0003). After adjusting confounding factors, the risk was still significant (adjusted OR = 5.02, 95% CI = 2.26–12.85, p = 0.0002). Conclusions The study results suggested that ARP is more likely to lead to the treatment modality of implant alone and reduce the need for staged GBR before implantation. Clinical relevance This study describes ARP capable of minimizing the need for staged GBR before implantation and shortening the treatment duration.

Aim: Today, dental implant applications have become the most preferred option in the treatment of tooth deficiencies. Long-term successful results in dental implant applications depend largely on the volume and quality of the hard and soft tissues in the relevant region. Insufficient soft tissues and alveolar crest resorption complicate implant applications. Grafts and additional surgical procedures are required to compensate for resorption and to provide bone augmentation. Shell technique, one of the augmentation methods used in the treatment of alveolar bone defects, is an important procedure for guided bone regeneration. The purpose of this case report is to describe the treatment of vertical and horizontal bone loss with the Shell technique using allogeneic cortical grafts. Methodology: A 58-year-old female patient without any systemic disease was admitted to our clinic with the complaint of tooth loss in the right posterior mandibular region. In the intraoral and radiological examinations, it was determined that the bone volume in the relevant region was not sufficient for dental implant. Two-stage surgical treatment was planned for the patient. First, vertical and horizontal bone defects were augmented with allogeneic cortical graft application under local anesthesia. After the healing process, dental implants were placed in the sufficient volume of the alveolar bone and the patient's treatment was completed. Conclusion: Allogeneic grafts in the treatment of alveolar crest defects; it is a good alternative to autogenous bone grafts,there is no need for a second surgical field and the resulting reduction in morbidity.   How to cite this article: Eriş Derkuş F, Yılmaz UN.

Antimicrobial Protection

Periodontal disease in the adult population is one of the most pressing problems of dentistry around the world. Thanks to the introduction of modern technologies in practice, it was possible to identify the main mechanisms of the development of this disease at the molecular and genetic level. The interaction of periodontal pathogens with immune factors of antimicrobial protection of the body is the basis of periodontal tissue inflammation and further leads to the destruction of the alveolar bone. Epithelial cells of the gum mucosa play a crucial role against periodontal pathogenic bacteria. Factors of innate immunity play a role not only in antimicrobial protection, but they also support the conditions necessary for the healing and regeneration of periodontal tissues. Therefore, various therapeutic approaches that affect the factors of innate immunity are considered as effective and promising. Clinical examination and determination of factors of innate immunity were performed in 115 patients. Healthy individuals made up a group of 30 people. Patients with chronic generalized periodontitis with varying degrees of severity were 85 people. Each patient underwent orthopantomography on the orthopantomograph Orthophosis XG DS/Ceph (SIRONA Dental System GmbH, Germany) in order to assess the state of the bone tissue of the jaws (the degree of destruction of the cortical layer, the degree of resorption of the interalveolar partitions). Targeted intraoral radiographs were used to assess the state of bone tissue and the quality of surgical treatment. Immunological methods of research were carried out in several stages. The findings of this article make the claim that the use of autologous complex immunopeptides in the surgical treatment of periodontitis reduces the time of achieving a therapeutic effect 2 times, resulting in the rapid relief of the symptoms of inflammation and acceleration of reparative processes.

Tibial fractures are very common injuries that require surgical management. For many cases, when the fracture involves the joint further complications occur, such as joint stiffness, osteoarthritis, aseptic necrosis of articular surfaces, ankylosis, infection complications, etc. To prevent joint stiffness open reduction and internal fracture fixation is used. That allows better positioning of fracture fragments forming joint surface and improve outcome. The article analyses results of surgical treatment of intraarticular fractures as well as biomechanical factors that are affecting the joint within the healing process and in later outcome period. Various treatment procedures are suggested to prevent development of osteoarthritis or to decrease its severity. The following options are used on all stages of treatment starting since the moment of injury, primary surgical procedures, rehabilitation period, and further non-surgical treatment in the internal medicine department. Important roles are assigned for use of chondroprotective drugs, intraarticular injections of Hyaluronic acid, physiotherapy and physical activity.

Abstract Objective: To examine the stability of mini-screws that invade a dental root by measuring the retention period/failure rate, and to illustrate their effects on paradental tissues. Materials and Methods: Three adult male beagle dogs received 48 orthodontic mini-screws. Half of the mini-screws were implanted to invade the roots, and the rest were placed in the middle of the alveolar bone. Half of the mini-screws were loaded immediately. The retention period of the mini-screws was documented. The dogs were euthanized after 8 weeks, and tissue samples were examined histologically. Results: The failure rate of the mini-screws that invaded the roots was 79.2%, and that of the mini-screws in the middle of the alveolar bone was 8.3%. The application of force had little effect on the failed mini-screws. Moderately injured roots were repaired with osteoid and/or cementoid tissues with normal periodontal ligaments, followed by recovery of the original configuration. Conclusion: Orthodontic mini-screws had a higher failure rate when placed to invade the dental roots. However, minimally damaged dental roots do not adversely affect the healing process.

Objective To evaluate the effectiveness of frozen cortical bone allografts (FCBA) in the treatment of severe radial and ulnar atrophic nonunion fractures. Animals Toy breed dogs with nonunion of radial and ulnar fractures (n = 15). Methods Severe atrophic nonunion fractures were treated with FCBA (eight infected and seven non-infected fractures). Radiographs obtained immediately after surgery, and 1, 2, 3, 6 and 12 months later were evaluated and scored for the periosteal reaction at the bone regeneration sites, the healing process in the bone connection areas at both the proximal and distal sites, and the bone remodelling process within the allografts. Results Improvements in the fracture-healing process and weight-bearing function were observed in all cases. Radiographic scores at the bone connection areas and within the allograft improved significantly over time (p < 0.05). There were not any significant differences in radiographic scores between the infected and non-infected groups. Clinical Significance Bone reconstruction with FCBA is effective in the treatment of radial and ulnar nonunion fractures associated with large bone defects, regardless of the infection status of the surgical site.

Tooth extraction is a dental treatment that is performed frequently in dentistry. This procedure will stimulate a sophisticated healing process involving a variety of biological factors although it takes a long time to complete. Three phases occur in this process i.e. the inflammatory phase, the proliferation phase, and the remodeling phase which aim to restore the tissue function. Several interventions can be used to accelerate bone formation after tooth extraction. Recently, hyaluronic acid (HA) has been commonly used in dentistry due to their essential physiological effects for the periodontal connective tissue, gingiva, and alveolar bone. Hyaluronic acidis a natural non-sulfate glycosaminoglycans compound that has high molecular weight consisting of D-glucuronic acid and N-acetylglucosamine. Hyaluronic acidis also a component of the extracellular matrix that plays an important role in morphogenesis and tissue healing. The mechanism of action of HA works in two ways, that is passive and active mechanism. The passive mechanism is depend on physical and chemical properties of HA that can change the molecular weight and concentration properties. The active mechanism of HA works by stimulating signal transduction pathway initiated by ligand binding with its receptors through autocrine or paracrine processes. The administration of HA can accelerate bone formation due to it can enhance bone morphogenetic protein (BMP) which belongs to the TGF- β superfamily that has high osteogenic capacity. The HA works through a passive mechanism that depends on its molecular weight and an active mechanism by increasing BMP activity.

Alveolar Ridge Preservation

Alveolar ridge preservation (ARP) therapy is indicated to attenuate the physiologic resorptive events that occur as a consequence of tooth extraction with the purpose of facilitating tooth replacement therapy. This randomized controlled trial was primarily aimed at testing the efficacy of ARP as compared with unassisted socket healing. A secondary objective was to evaluate the effect that local phenotypic factors play in the volumetric reduction of the alveolar bone. A total of 53 subjects completed the study. Subjects were randomized into either the control group, which involved only tooth extraction (EXT n = 27), or the experimental group, which received ARP using a combination of socket grafting with a particulate bone allograft and socket sealing with a nonabsorbable membrane (dPTFE) following tooth extraction (ARP n = 26). A set of clinical, linear, volumetric, implant-related, and patient-reported outcomes were assessed during a 14-wk healing period. All linear bone assessments (horizontal, midbuccal, and midlingual reduction) revealed that ARP is superior to EXT. Likewise, volumetric bone resorption was significantly higher in the control group (mean ± SD: EXT = −15.83% ± 4.48%, ARP = −8.36% ± 3.81%, P < 0.0001). Linear regression analyses revealed that baseline buccal bone thickness is a strong predictor of alveolar bone resorption in both groups. Interestingly, no significant differences in terms of soft tissue contour change were observed between groups. Additional bone augmentation to facilitate implant placement in a prosthetically acceptable position was deemed necessary in 48.1% of the EXT sites and only 11.5% of the ARP sites ( P < 0.004). Assessment of perceived postoperative discomfort at each follow-up visit revealed a progressive decrease over time, which was comparable between groups. Although some extent of alveolar ridge remodeling occurred in both groups, ARP therapy was superior to EXT as it was more efficacious in the maintenance of alveolar bone and reduced the estimated need for additional bone augmentation at the time of implant placement (ClinicalTrials.gov NCT01794806).
