Subpontic osseous proliferation
Abstract:
Nine patients, five women and four men, demonstrated bone growth in an edentulous region of the posterior mandible covered with a pontic. The reasons for this bone growth could include genetic predetermination, functional stresses, and chronic irritation. This bone growth has important clinical and basic science implications. The condition was seen only in adults, only in the mandibular posterior region, and with a variety of pontic designs. Subpontic osseous proliferation was documented in nine patients, but no conclusion about the etiology was made.

Compact Bone
Compact bone, also called cortical bone, is the denser, stronger of the two types of bone tissue. It is found under the periosteum and in the diaphyses of long bones, where it provides support and protection. The microscopic structural unit of compact bone is called an osteon, or haversian system. Each osteon is composed of concentric rings of calcified...

The process begins when mesenchymal cells in the embryonic skeleton gather together and differentiate into osteogenic cells, which then develop into...
Cranial Bones: Lateral View
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...
Spongy Bone
Spongy bone is more porous, and less dense compared to compact bone. It is composed of concentric lamellae that are arranged irregularly to form the trabecular network. In some bones, the spaces between trabeculae contain red marrow, where...
