Replacement of missing teeth in the posterior maxilla is always a challenge for the treating implant surgeon as the posterior maxilla has several obstacles in the form of quality, quantity, the anatomy of the maxillary sinus, and inaccessibility.
To overcome these deficiencies, several surgical procedures such as sinus lift, bone augmentation, tilted implants, short implants, and zygomatic implants were tried. Since these procedures have their own limitations, pterygomaxillary region provides us an excellent place for placement of implant and rehabilitation of posterior maxilla.
The reasons considered for difficulty in rehabilitating the posterior maxilla is mainly due to the anatomy of maxilla due to the presence of maxillary antrum, poor quality and quantity of bone. To overcome these difficulties sinus lift procedures is to be done. For doing sinus lift procedure bone graft is needed. after placing bone graft we have to wait for 3-4 months for bone formation in that area and then again wait for next 3-4 months after placing the implant in that region. Hence it’s a very delayed procedure and patient have to wait for a longer time. To prevent these problems, pterygoid implants are best option..@dr richa’s cosmodent cosmetic & dental clinic @dentist in mira road@affordable implants
