CBCT Assessment of Dental and Skeletal Changes Using the Damon versus Conventional (MBT) System

The evolution of the shape of the human dental arch is distinct when compared to other primates, while hominid evolution has demonstrated that the arch form in man is parabolic. For over 100 years the size and shape of the ideal dental arch has been used for diagnosis and treatment of malocclusions and two diverging methods of therapy: extraction versus non-extraction. Proponents of non-extraction treatment have indicated that extractions result in a detrimental result in profile and smile esthetics, large buccal corridors and faulty final occlusions. Recent reports indicate that extraction therapy does not negatively impact on soft tissue , nor does it negatively affect smile esthetics .

Damon versus Conventional (MBT) System
If the current state of evidence points in the direction that extraction therapy has no detrimental effect in facial esthetics and provides a superior occlusion to non-extraction treatment, one would expect a greater predominance of patients treated with the extraction of teeth to successfully resolve their malocclusions. However, with the advent of the Damon philosophy and through the use of self-ligation with low force, low friction arch wires, the pathway to non-extraction treatment has been resurrected and gaining favor in orthodontic therapy.

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>>>>>>
