Forensic Dentistry..
With the many good things brought in this new millennium new challenges of terrorism, natural disasters and high rate of crime have also arisen. Dental hard tissues being extremely resistant to fire, are usually the only remains after an extended period of burial. Since the late 1890s, forensic dentistry has gradually established itself as important, often indispensable, in medico legal cases, in particular for identification of the dead.

"Forensic dentistry is the study and practice of aspects of dentistry that are relevant to legal problems."Forensic odontologists are highly experienced, specially trained dentists who use their expertise to help identify unknown remains and trace bite marks to a specific individual. Forensic odontologists or forensic dentists are typically called in to:

 

 

  • Identify human remains that cannot be identified using fingerprints or other means
  • Identify bodies in mass fatalities, such as plane crashes and natural disasters
  • Determine the source of bite mark injuries, in cases of assault or suspected abuse
  • Estimate the age of skeletal remains

 


Recent tragedies and past and present situations have increased awareness concerning the importance of forensic dentistry in identification of victims. Hundreds of cases are seen every year in India relating to identification problems and bite mark analysis yet Forensic dentistry is not yet fully introduced into the dental curriculum as a subject and the growth from the ancient, past to present has not been uniform.

 

 

 

IMPLANT PROTECTED OCCLUSION

Clinically, natural occlusal concepts can be applied to implant prostheses. However, a natural tooth has a support design that reduces the forces to the surrounding crest of bone compared to the same region around an implant. Due to lack of the periodontal ligament, osseointegrated implants, unlike natural teeth, react biomechanically in a different way to occlusal force. It is therefore believed that dental implants may be more prone to occlusal overloading, which is often regarded as one of the potential causes for peri-implant bone loss and failure of the implant/implant prosthesis. Thus if a clinical condition is likely to increase biomechanical stresses, dentists should implement occlusal mechanisms to decrease the stresses and develop an occlusal scheme that minimizes risk factors and allows the restoration to function in harmony with the rest of the stomatognathic system.

Implant-Protected Occlusion is that occlusal scheme which reduces the forces at the crestal bone/implant interface. Implant-protected occlusion can be accomplished by increasing the surface area of implants, decreasing the width of the occlusal table, improving the force direction, and reducing the magnification of the force. By doing these things, we can minimize overload on bone-implant interfaces and implant prostheses, to maintain an implant load within the physiological limits of individualized occlusion, and ultimately provide long-term stability of implants and implant prostheses.

DENTAL IMPLANTS - A JOURNEY...


PART- II

The evolution in the field of implantology continues as dental implant technology moves from traditional implants and components with traditional results to the next level of technology that has industry leaders turning their heads. The most critical advancement for implant dentistry saw a philosophical reversal. In the yester years, surgeons based implant positioning on the location or availability of the bone, for osseous grafting techniques were in their infancy. Today, this is not the case. The high predictability of current augmentation methods allows for implantation based on prosthetic desires instead of biologic limitations. Thus the modern implantology is prosthetic-driven, dictating the recent innovations of the design, ease and aesthetics.

In recent years, a new technology of computer-assisted surgery for oral implantology application have been developed and introduced clinically. Computerized navigation system offers intraoperative guidance of the surgical instruments based on a presurgical plan. Computer assistance provides three dimensional (3D) orientations of surgical instrument position and trajectory, displayed on a monitor in real-time within patient’s 3D imaging data.

The field of dental robotics though still in its infancy, is a new area of research full of opportunities with many applications. Some of its popular applications include haptic guided dental implants, user controlled implant surgery using a virtual environment, and preoperative planning. However, none of these applications involve total automation of the dental process. The area of automatic robotic dentistry is very new and there is much to learn.

With time, some of these innovations may become conventions; others will end up historical side-notes. As always, we rely on biologic principles as well as longer-term clinical investigation to guide our judgment. Clinicians, as individuals and as a collective, must be able to discriminate between a fad and a breakthrough, to separate the wheat from the chaff as implant dentistry is no longer considered experimental or exotic, but is a mainstream dentistry.

Eagle Syndrome

Symptoms like orofacial pain, joint noise, restricted jaw function, headaches, earaches, neck and shoulder pain though commonly associated with temporomandibular disorders, may be present in other diseases as well, thus making a precise diagnosis difficult and time-consuming for many clinicians. The styloid process and associated structures have been implicated in a variety of craniomandibular dysfunctions and pain complaints. Eagle’s syndrome, a rare condition is an aggregate of symptoms that are the direct result of an elongated styloid process (greater than 3 cm) or a calcified stylohyoid ligament.

Patients with this syndrome tend to be between 20 and 50 years of age but it has been recorded in teenagers and in patients > 75 years old. It is more common in women with a male:female ratio of 1:3. There are 2 possible clinical expressions attributable to elongated styloid process. Patients with the “Classic Eagle Syndrome” can present with unilateral sore throat, dysphagia, tinnitus, unilateral facial and neck pain, otalgia and a sensation of foreign body in the throat. In patients with the “Vascular form of Eagle syndrome”, the elongated styloid process is in contact with the extracranial external or internal carotid artery. This can cause a compression or a dissection of the carotid artery causing pain along the distribution pattern of the artery which is provoked and exacerbated by rotation and compression of the neck.

Patients with vague head and neck pain symptoms can lead to an extensive differential diagnosis. Medical history is the main guide for the diagnosis of Eagle’s syndrome. Palpation of the tonsillar fossa is then necessary to feel the elongated styloid process, which may elicit the same pain and symptoms as experienced by the patient. Imaging is important and is diagnostic. The enlarged styloid may be visible on an orthopantogram or a lateral soft tissue X-ray of the neck. Visualizing the styloid process on a CT scan with 3D reconstruction is the suggested imaging technique. For both the classic and vascular form, the treatment is surgical. A partial styloidectomy is the preferred approach.

Dental Implants - a Journey...


Part- I


The key to success is often the ability to adapt to the new. Implant is the most exciting idea in modern dentistry. It is the herald of a new era that can benefit esthetically, psychologically, and physically most of the partially and many of the totally edentulous patients.

The history of implants is as old as the history of dentistry. Dentistry was more of an art than a science, in the early years. The history of implant dentistry spans not only decades, but millennia. The ancient cultures of the world—in Egypt, Honduras, China, and Turkey, among others—substituted missing dentition with shells, stones, ivory, and other human or animal teeth. Later on, dentists used to drill holes into the gums to snap removable dentures. But the cause of failure of these early attempts of implant placement was their unscientific basis.

Dr. Branemark introduced modern implant techniques and the notion of osseointegration around 1980s. At the time, techniques were focused on the fully edentulous patient or dental arch. Dental implants and the restorative abutments were designed for attachment of removable dentures or modified fixed dentures. Adaptation to support bridge-like prostheses followed, but only after a few years. Today, implant dentistry has expanded into every aspect of tooth replacement, starting from replacing a missing single tooth, multiple teeth to full mouth rehabilitation.

The use of dental implants as the preferred method of tooth replacement continues to escalate worldwide and with the introduction of innovative technologies and techniques, the ability to replace missing teeth with the function and beauty of a natural tooth is now possible.
