The vertical height of the alveolar bone and the amount of remaining bone are important factors in the long-term suc cess of implants. If the remaining bone is insufficient, procedures such as vertical alveolar ridge augmentation, like guided bone regeneration, are necessary for ideal implant surgery. Among the non-resorbable membranes that can be used in these procedures, titanium mesh offers advantages such as maintaining space for bone grafting, protecting the underlying graft material, and allowing adjustment to match the defect site for desired shaping. However, fixation of titanium mesh, which is crucial in determining the overall success of the surgery, requires the use of multiple screws and may result in membrane ex posure during the healing process. To overcome these problems, a recent development involves the use of fixture-supported titanium-mesh, which has demonstrated good results. This study suggests that vertical alveolar ridge augmentation using fixture-supported titanium mesh can resolve conventional problems and can be considered an effective and reasonable strat egy for achieving ideal implants.
Cemento osseous dysplasia (COD) is a lesion that occurs in the periapical and tooth-bearing area where normal bone tis sue is replaced by fibrous tissue and metaplastic bone. The cause is not clearly known. COD is often discovered incidentally without any symptoms. It is more common in females and mandibular molars. The involved tooth is vital. In radiological imaging, the lesion has a well defined border. The internal density of the lesion depends on the maturity of the lesion. Ra diolucent and mixed lesions of COD are sometimes mistaken for periapical lesions and root canal treatment is performed. Because COD has limited growth, no special treatment is required. Accordingly, The author reports cases of COD in man dibular teeth region referred from other clinics for accurate diagnosis or removal of the lesions and presents the cone beam computed tomography images of the cases to help clinicians make an accurate diagnosis.
Ultrasonography is the newest imaging modality used for the diagnosis and interventional procedures of oral and maxillofacial region in dentistry now. Although it is not the first and foremost imaging modality in the diag nosis of temporomandibular disorders, it can be the complementary and alternative one for arthrography, CBCT, CT, and MRI. Ultrasonography of temporomandibular joint (TMJ) does not show the anatomical structures easy to understand like CT or MRI, but it gives some useful diagnostic information on internal derangement, capsuli tis, and degenerative joint disease of TMJ. Ultrasound image-guided injection to TMJ can improve the accuracy and efficacy, and can minimize the potential damage to adjacent tissues including major vessles and nerves.
Headaches can often cause the symptoms from the pain of the spine to toothahe, which can spread along the neural segmentation. However, the reality is that we as dentists do not process any information in these pa tients, and in most cases, we prescribe pain medications or refer the patients to internal medicine or neurology department. In this review, we try to address some important issues that dentists can approach and be aware of headaches in dental clinics.
Temporomandibulr disorders(TMDs) is a comprehensive term that encompasses functional disorders affect ing the masticatory system, including the temporomandibular joint and masticatory muscles. This term contains various diseases, and the presence of multiple etiologies makes the diagnosis and treatment of TMDs more complex. Therefore, this paper aims to explore the classification and diagnosis of TMDs, with a focus on the DC/TMD. Additionally, this paper investigated the definitive treatment and supportive therapy for TMDs.
