A conventional dental implant is usually known as a “Two Piece” implant which consists of the root component and the tooth component in separate bits.
The root component ( implant ) is placed into the jaw bone and to it is connected the tooth component ( abutment ) usually using a tiny screw.
The abutment is then prepared or customized to take the final crown. Conventional dental implants are the main type of implants and are an extremely effective long-term solution for missing teeth.
In total 2 trips are needed over about 4-6 months. The first trip usually requires about 3-5 days and the second trip usually requires about a full week.
This type of implants are performed in dental clinics but the amount of time needed to complete the treatment is more.
How they are done ?
Extraction of the tooth is performed and the implant is placed all in one visit. Sometimes artificial powdered bone material is placed into the empty extraction site to ensure there is enough bone to support the implant. This is called a minor bone graft or a socket graft.
If there is not enough bone in the upper jaw molar or premolar implant to be placed bone material is placed in the extraction site and the sinus membrane moved upwards. This is called a sinus lift.
In most cases extractions, placement of implants and a socket graft or sinus lift can be done in one appointment. If major bone grafts ( block grafts ) are required it can entail an extra trip before the implants can be placed. This can be determined by looking at a panoramic x-ray or CT scan.
After the implant is screwed into the jaw bone the gums are then sealed over the implant. It then takes about 3-6 months for the implant to osseointegrate with your jaw bone before it is stable enough to support the abutment and crown.
The implant placement can take place in just one appointment but an initial consultation and diagnosis visit, follow up for suture removal and post operative check-up visits are required.
After the implants are stable you would return to have the abutment and crown fitted. During this visit, the gums are opened up and the abutments are attached to the implants and then impressions are taken of the abutments and surrounding teeth in order to send off the dental laboratory where the crowns are crafted.
It is important that good impression are taken so that when the crowns are fitted they fit properly align and match the bite of your other teeth and have a proper minimal margin at the gum line for best appearance.
It takes a few days for the lab to make the crowns and the whole process usually takes about 3 appointments over the course of a full week.
Benefits of conventional dental implants:
Provide an effective long-term solution for missing teeth.
Prevent bone degeneration which can often occur after tooth loss or when a person wears a denture for a number of years.
Creates a natural attractive smile as implant tooth will look exactly like a natural tooth
No risk of irritation to the gums or interference with neighbouring teeth.
Provides the highest standard of treatment.

Implants supported fix teeth in just 72 hours
The teeth are situated in less dense bone portions of the jaw bones called the alveolar bone. This is also known as the crestal bone of the jaw. This less dense alveolar or crestal bone gradually starts getting resorbed and recedes once the teeth are lost.
The bone which ultimately remains after regression of the alveolar bone following loss of teeth is the basal bone which lies below the alveolar bone. The basal bone is less prone to bone resorption and infections. It is highly dense, corticalized and offers excellent support to implants.
When all teeth are lost, the body recognizes that the portion of the jaw bones supporting the tooth roots is no longer necessary. Thus the body begins to re absorb the minerals in these areas to the rest of the body where they can be used. This process is called resorption. The jaw bone thus starts shrinking slowly. After 10 to 20 years, often there is very little jaw bone left to even support your dentures. This in turn leads to collapse of the face due to loss of vertical facial height and the soft tissues turn flabby as the jaw muscles do not have much work as it used to have earlier.
The significant advantage with dental implants is that the implants stimulate the bone like natural tooth roots do during the process of chewing. Thus, the crestal jaw bone which gets resorbed in the normal course after removal of teeth, is retained, thereby maintaining the facial contours. Though they are more expensive initially, in the long run, helps avoid major dental surgical procedures including bone grafting and the like. They also help reducing the requirement of new dentures or implants.
Conventional implants are placed in the crestal alveolar bone which comprises of bone of less quality and is more prone to resorption. The basal bone is less prone to bone resorption owing to its highly dense structure. The implants which take support from the basal bone offer excellent and long lasting solutions for tooth loss.

As the name suggests, a crown is a cap or covering for a tooth. It is used when your tooth is discoloured, cracked or broken, heavily filled or if fillings have been lost.
When would you need a crown?
Cover discoloured or worn teeth
If you feel that your teeth are becoming more transparent or becoming darker in colour, they may be wearing down. Your dentist will discuss the reasons behind this as it is important that they are addressed first. If your dentist recommends a crown restoration, then this crown will be fabricated to resemble the natural shape and strength of your existing tooth through the use of a ceramic material.
Replacement of a large filling
If your teeth are heavily filled, they may be at risk of fractures or de-bonding of fillings. Frequent replacement of fillings can lead to loss of precious tooth structure. Repeated dental treatment on the same tooth may lead to deepening of the filling and subsequent nerve inflammation. To avoid these complications, your dentist may recommend that a crown is constructed before the filling becomes too large and remaining tooth structure is too short to support a crown.
To stop a tooth from further cracking or fracturing
If your tooth is showing fine lines and cracks or you occasionally feel sensitivity when biting into sticky or hard foods, your tooth may have a deep crack or may be at risk of complete fracture. This is common for heavily filled teeth, especially where an amalgam filling is in place. Your dentist may recommend a crown to restore the tooth and protect its cusps from splitting apart and may suggest replacing any amalgam with a ceramic restoration.
To anchor a bridge replacing a missing tooth
If a tooth is missing or lost, your dentist will discuss the options for tooth replacement. This may involve the placement of an implant or tooth supported bridge. If two or more teeth directly adjacent to the lost or missing tooth are at risk of fracture or are discoloured and need crowns, a bridge may be a good option to replace the missing tooth. When the bridge is produced, a porcelain tooth (pontic) is fused to the two or more crowns on either side and once the crowns are fitted onto the adjoining teeth, the porcelain pontic appears to be emerging out of the gum. A bridge may be a suitable course of treatment for you if you are unable to have an implant due to issues with your overall health or dental health.
After root canal treatment
Root canal filled teeth are prone to fractures, due to the nature of root canal treatment and hollowing out of the tooth in the process. Dentists highly recommend crowning most root canal filled teeth to protect them from fractures and further bacterial infections.
A dental bridge is a ceramic structure, spanning the gap left by a missing or extracted tooth. A ceramic tooth (pontic) is fused between two or more porcelain crowns on either side of the missing tooth that serve as anchors. The anchor teeth are shaped to accommodate the crowns and then a bridge is bonded securely over these teeth. The pontic tooth and the crowns on either side are matched to the colour and the shape of your existing teeth to give it a more esthetic and natural appearence.
A denture is an appliance which is worn to replace lost or missing teeth to enable you to enjoy a healthy diet and smile with confidence. There are 2 types of dentures:
Complete denture (CD): A complete or full denture is one that replaces all of the natural teeth in either the upper or lower jaws.
Removable partial denture (RPD): A partial denture fills in the spaces created by lost or missing teeth and is attached to your natural teeth with metal clasps or devices called precision attachments
Complete denture may be ‘Conventional’ or ‘immediate’.
A conventional denture is made after the teeth have been removed and the gum tissue has healed, usually taking 4-6 weeks. During this time, the patient will go without teeth.
Immediate denture is made in advance and immediately placed after the teeth are removed, thus preventing the patient from having to be without teeth during the healing process. Once the tissues shrink and heal, adjustments need to be made.
Removable Partial Dentures may be any one of these types:
Traditional denture with a metal framework to make the denture strong, light and biocompatible
Flexible or unbreakable denture
Due to technological advances in dentistry, the denture can even be fixed to the jaw bone by using dental implants. This type of implant supported overdenture improves quality of life and also gives immense satisfcation.
