Bone Augmentation
Bone augmentation is a collective term used in dental surgery to refer to a number of reinforcement surgeries that are done for jaw defects. The Onlay augmentation or grafting is a unique bone augmentation method that can be used on both the upper and lower jaw. This is done when the alveolar ridge regression is uneven. The inlay surgery, also known as a sinus lift is done when there are no teeth remaining in the jaw and the alveolar ridges have receded evenly. Jaw bones are augmented by using bones from other parts of the patient’s body, bone from animals such as cattle or even synthetically manufactured bone. Transplanted human bones have the highest success rate as they heal best when compared to animal or synthetic bones. The bone size is another important factor that must be taken into consideration during transplantation as large bone chunks may not always suit the purpose. Sometimes, both inlay and outlay surgical methods are combined for better aesthetic results. Watch this video to know more about bone augmentation.

Dear Dr. Misch! In this video we talk about bone segments which aren't used in dental surgery. When segments beyond a particular size are not transplanted microvascularly a depletion syndrome kicks in, such as when, for example, half of the lower jaw is replaced in patients with tumours of the jaw. Since, in dental surgery, it is only small segments that are exclusively made use of for augmentation of the alveolar ridge, this syndrome doesn't occur at all - this will also be mentioned in the video. Many patients who need reconstructive surgery after tumour operations or severe injuries are surprised to learn that the reconstruction of the face isn't as simple as the bone-building operations they've heard of that are done by dentists. With this video clip we're trying to make things a bit clearer and we'll develop this point better in the revised version of this clip, so thanks for your feedback.

Where did you get the information on large bone blocks? Your "hypothesis" on large bone graft healing is entirely wrong and unfounded in the literature. Someone at checkdent needs to do their homework!
