What is maxillary tuberosity?
The maxillary tuberosity is the most hind-most (distal) aspect of the upper jaw (maxilla), housing the sockets of the upper wisdom teeth, with its back (posterior) border curving upward and distally.
Why is maxillary tuberosity important?
The maxillary tuberosity is especially important for the stability of maxillary denture. Large fractures of the maxillary tuberosity should be viewed as a grave complication. The major therapeutic goal of management is to salvage the fractured bone in place and to provide the best possible environment for healing.
Is maxillary tuberosity a bone?
Maxillary Tuberosity: An Overlooked Site for Block Grafts Rich in Cortical-Cancellous Bone. A well-known consequence of tooth loss is the concomitant loss of the supporting alveolus.
What is maxillary tuberosity fracture?
Fracture of the maxillary tuberosity is a potential sequela of removal of maxillary posterior teeth. Often, a small fragment of bone is able to be carefully dissected from its periosteum and delivered with the tooth.
How is maxillary tuberosity formed?
At the lower part of the infratemporal surface of the maxilla is a rounded eminence, the maxillary tuberosity, especially prominent after the growth of the wisdom tooth; it is rough on its lateral side for articulation with the pyramidal process of the palatine bone and in some cases articulates with the lateral …
What is tuberosity fracture?
The greater tuberosity is the prominent area of bone at the top of the humerus and is the attachment for the two large, powerful rotator cuff muscles – supraspinatus and infraspinatus. It is injured/fractured in a fall by either landing directly onto the side of your shoulder or landing with your arm outstretched.
What attaches to the maxillary tuberosity?
A smaller superficial head of medial pterygoid also arises from the maxillary tuberosity and the neighbouring part of the pyramidal process of the palatine bone immediately above the tuberosity.
Where is the maxillary tuberosity located?
Maxillary tuberosity – The maxillary tuberosity is the rounded end of the alveolar process of the maxilla. This radiopaque structure appears bilaterally on maxillary molar periapicals and often on maxillary premolar periapicals and molar bitewings.
What is a tuberosity made of?
The proximal tibia has two ossification centers, the proximal tibial epiphysis and the tibial tuberosity, which are separated by a cartilage bridge (see the image below). Before ossification, the tibial tuberosity is composed of fibrocartilage that has good tensile strength.
Where is the tuberosity?
The ischial tuberosity is a rounded bone that extends from the ischium — the curved bone that makes up the bottom of your pelvis. It’s located just below the ischial spine, which is a pointed bone that extends up the backside of your pelvis.
What is the function of the tuberosity?
In brief, tuberosity and tubercle are two types of protrusions or eminences in the bones of the human skeleton. And, their function is to serve as an attachment for skeletal muscles.
