DENTAL IMPLANTS - A Short Note

By -

Dental implants are metal posts or frames that are surgically positioned into the jawbone beneath your gums. The dental implant acts as a replacement for the root of a missing tooth .Having a dental implant fused to the jawbone is the closest thing to mimicking a natural tooth because it stands on its own without affecting the nearby teeth and has great stability.The process of fusion between the dental implant and jawbone is called “osseointegration.
Most dental implants are made of titanium. The main reason why titanium is often used in the body is due to titanium’s biocompatibility and, with surface modifications, bioactive surface. Dental implants can be used to replace a single tooth, several teeth, or all of the teeth. The goal of teeth replacement in dentistry is to restore function as well as esthetics.
STRUCTURE OF DENTAL IMPLANTS

Implants are also threaded ; when they are screwed into the bone, they collect bone tissue so that the implant is as stable as possible when it integrates into the bone.Abutment support the implant.
Types of Dental Implants :
Endosteal implants — these are surgically implanted directly into the jawbone. These dental implants are the most commonly used for two-stage procedures. They are surgically implanted directly into the jaw bone and are an alternative to bridges or detachable dentures

Subperiosteal implants — these consist of a metal frame that is fitted onto the jawbone just below the gum tissue. As the gums heal, the frame becomes fixed to the jawbone. Posts, which are attached to the frame, protrude through the gums. As with endosteal implants, artificial teeth are then mounted to the posts.

The brackets are linked to each other with a thin archwire, which puts pressure on the teeth to cause them to move slowly into the correct position.The ties are also prone to collecting plaque, which can be unpleasant. They are durable and strong. Ceramic Braces  : Made of Ceramics instead of Metal, they have clear or tooth colored brackets so they are less noticeable than metal brace

DENTAL RADIOGRAPHY- A Short Note

By -

Radio graphs (X-rays) are necessary for the evaluation and diagnosis of many oral conditions and diseases. Dentists use radiographs for many reasons: to find hidden dental structures, malignant or benign masses, bone loss, and cavities. They are diagnostic, but they can also be preventative, by helping a dentist diagnose potential oral care issues in a patient’s mouth before they become a major problem. An x-ray is a type of energy that passes through soft tissues and is absorbed by dense tissue. Teeth and bone are very dense, so they absorb X-rays, while X-rays pass more easily through gums and cheeks.X-rays are divided into two main categories, intraoral and extraoral. Intraoral is an X-ray that is taken inside the mouth. An extraoral X-ray is taken outside of the mouth. Intraoral X-rays are the most common type of radiograph taken in dentistry. The benefits of X-rays are well known: They help dentists diagnose common problems, such as cavities, gum disease and some types

THUMB SUCKING AND DENTAL CARE

Thumb sucking  is a natural reflex for children. Kids suck their thumbs because it's comforting and calming. It can also be soothing, and many babies and toddlers use it as a coping mechanism when anxious or separated from their parents. The habit helps to induce sleep, and children may suck their thumbs in the evening before bedtime. After permanent teeth come in, sucking may cause problems with the proper growth of the mouth and alignment of the teeth. It can also cause changes in the roof of the mouth. The intensity of the sucking is a factor that determines whether or not dental problems may result. If children rest their thumbs passively in their mouths, they are less likely to have difficulty than those who vigorously suck their thumbs. Some aggressive thumb suckers may develop problems with their baby (primary) teeth. The best time to discourage thumb sucking is by age four. By this time, prolonged sucking could begin to affect your child's mouth and devel
