Autogenous Demineralized Dentin Graft for Third Molar Socket Regeneration

The management of the osseous defects distal to the second molars as a result of the surgical removal of impacted wisdom teeth can be a challenge. The reasons for third molar extraction are varied like pericoronitis, decay, risk of damage to adjacent teeth, cyst or tumor formation, or to facilitate orthodontic treatment. The postextraction bone loss, a physiological phenomenon will take place with alveolar resorption and the subsequent formation of bone within the socket follows osteoblastic differentiation of osteoprogenitor cells. This phenomenon continues for a period of weeks. However, studies have documentedthat the bone volume following extractions decreased by 50% within 12 months,and two-thirds of this resorption took place during the first 3 months afterextraction. Bone resorption will result in a loss of socket width three-dimensionally that subsequently hamper the native alveolar ridge contour. Therefore, maintaining 3-dimensional alveolar bone volume is required for ideal esthetic and functional restorations.
Autogenous Demineralized Dentin Graft
Bone grafting to augment skeletal healing has become one of the most common surgical techniques in recent years. Despite these essential properties drawbacks involving autogenous bone grafting include need for the second surgery, donor site morbidity and limited availability have led to the challenging study for alternative biomaterials with osteoinductive potential.

Harvesting Free Palatal Masticatory Mucosal Graft Using 3a Mucotome

Image
The technique of free autogenous gingival grafting (FGG) has undergone little modification since its introduction by Bjorn in Scandinavia in 1963 and by King and Pennel inthe United States in 1964. The technique is widely used to treat a variety of mucogingival problems such as insufficient or lack of attached gingiva, the presence of high frenum attachments, shallow fornix and denuded roots following gingival recession.  FGG can be procured from donor site using scalpels, gingivectomy knife or palatal shaving knife (Paquette knife). The donor site is frequently the palate, although the use of edentulous ridge areas, tuberosity and attached gingiva has also been described. Scalpel is most commonly used and conventional method for procuring gingival auto grafts. Gingivectomy knife, although not commonly used, also works on similar principle. Since the scalpel blade is straight and stiff and the palate is curved, repeated incisions to release the graft from underlying conn...

Indications for Orthognathic Surgery

Image
Orthognathic surgery (OS) is a surgical intervention that alters relationships of the jaws and dental arches. The treatment involves a combination of orthodontics and maxillofacial surgery.  Orthognathic Surgery It is used to correct dentofacial deformities that cannot be treated with acceptable results by conventional orthodontics. The first description of a surgical intervention to correct a malocclusion was by Hullihen in 1849. The most frequently used surgical procedures for correcting the relationship of the jaws are Le Fort I osteotomy and sagittal ramus split osteotomy. Also often used are vertical ramus osteotomy, inverted L osteotomy, and variations and combinations of the above. Read More>>>>>>

Dental Ailments may be risky for Cardiac Patients

Image
Patients that are suffering from cardiac t=disorders are susceptible to physical and mental stress. Dental ailments add to the stress further as these patients are unable to cope with the pain due to cardiac disorders. These patients may encounter medical emergencies in case of dental disorders and they may demand multi disciplinary approach to achieve the success. Additionally, the results of cardiac surgery may suffer if the oral cavity is not maintained well since there is always a fear of infection affecting the heart from the oral cavity. Hence, the cardiac surgeon has to refer surgical patients to a dentist for oral prophylaxis and to treat any oral infections before cardiac surgery to prevent infective endocarditis. PDF LINK
