Immediate dental implant placement and cantilever bridge
What is immediate dental implant placement? Immediate implant placement is when an implant is placed at the same time as the natural tooth is extracted. It was first reported in 1976. It has similar high success rate as traditional delayed implant placement. The main benefits of immediate implant placement are reduced treatment time and number of visits. If immediate loading is possible, tooth extraction , implant and temporary crown can be completed on the same day (same

Against all the odds, the dental implants have survived for 13 years.
Dental implants have revolutionized dentistry and the replacement of teeth since Dr. P. Brånemark first placed modern dental implants in his patients in 1965. Dental implants are very successful if they are placed following basic principles of dental implant surgery. One of these principles is regarding mesial-distal positioning of implants. There should be at least 1.5 mm of space between the implant and any adjacent teeth, and 3 mm of space between adjacent implants. O

Peri-implantitis
Peri-implantitis is a destructive inflammatory process affecting both soft and hard tissue surrounding an osseointegrated dental implant in function. Similar to a natural tooth, bacteria can build up on the base of the implant, below the gum line. Over time, the bacteria irritate the gum tissue, causing it to become inflamed, damaging the tissue and if not caught early, causing the bone structure below the implant to deteriorate. Peri-implant diseases are classified into t

Implant supported cantilever bridge
In this case, there are two front teeth missing with limited space. The gap is not wide enough for 2 implants and one implant supported cantilever bridge will be the best option. Computer guided implant surgery performed after 3D planning - flapless, minimal trauma and quick recovery. 3 months after implant surgery, showed complete osteo-integration. Cantilever bridge inserted. Now the patient can smile again and also it's easy to floss and maintain oral hygiene . #D

Multiple Dental Implants
When a number of teeth are missing, multiple dental implants are the best option to give you the feeling of real teeth and easy maintenance of oral hygiene. In this case, all the premolars and molars are missing, which means there is no back teeth to chew on. A lower partial denture was made but the patient couldn't stand it because of lack of stability and comfort. Eventually three implants resolved all the problems. Three months after implant surgery , the intergrated im

Sinus lift and immediate implant placement.
A patient with a missing upper first molar requested to replace the missing tooth. On examination, we found an upper left first molar missing and root caries on the second molar, which meant the second molar was unrestorable and a dental bridge would not be an option. The options left would be a removable denture or a dental implant . The patient chose the dental implant because he didn't like dentures. After the x-ray was taken, it showed that it would not be a simple and

Sinus Lift.
Sinus lift is also called sinus augmentation. It is surgery to add bone to upper jaw, specially in molar and premolar area. The sinus membrane will be "lifted" to make room for bone grafting. From CBCT , we can see the sinus floor was too low and the remaining bone was not enough for implant. In this case, lateral window technique was used. Sinus membrane lining was raised and granules of bone-graft material was packed into the space after a small, oval window was opened in
