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.

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.

Peri-implant diseases are classified into t

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
