Decontamination of SAE Surface: An In Vitro Study

Titanium is the preferred material for dental implants because of its mechanical strength and protective oxide layer, which is naturally formed and regenerated immediately in presence of air and/or aqueous media, providing protection against corrosion. Due to these characteristics, in terms of roughness and porosity in the microscopic range (depending on the treatment surface), commercially pure titanium (CP Ti) or the alloy TiAl4V are unique for osteointegration providing stability of the implant to survive the mechanical requirements of the oral environment.

Decontamination of SAE Surface
Although, maintenance has been suggested after placement of the implant to ensure a favorable environment for osteointegration to occur and continue. Such procedures are designed to diagnose and treat inflammatory responses as known as peri-implantitis, an inflammatory process around an implant, characterized by soft tissue inflammation and loss of supporting bone in the peri-implant area. The presence of bacterial biofilm and its metabolic activity alters the oxide layer properties in terms of roughness and chemical composition. The infection progressively spreads among the implant surface and lead to a failing implant. Thus, the clinician has the option to either remove the infected implant or perform debridement and decontamination of the implant surface to remove such biofilms to claim a further reosseointegration process.  Read more.............

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 connecti

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

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>>>>>>
